Statutory Disallowance of Deductions for Certain Qualified 
Conservation Contributions Made by Partnerships and S Corporations

AGENCY: Internal Revenue Service (IRS), Treasury.

ACTION: Final regulations.

-----------------------------------------------------------------------

SUMMARY: This document contains final regulations concerning the 
statutory disallowance rule enacted by the SECURE 2.0 Act of 2022 to 
disallow a Federal income tax deduction for a qualified conservation 
contribution made by a partnership or an S corporation after December 
29, 2022, if the amount of the contribution exceeds 2.5 times the sum 
of each partner's or S corporation shareholder's relevant basis. These 
final regulations provide guidance regarding this statutory 
disallowance rule, including definitions, appropriate methods to 
calculate the relevant basis of a partner or an S corporation 
shareholder, the three statutory exceptions to the statutory 
disallowance rule, and related reporting requirements. In addition, 
these final regulations provide reporting requirements for partners and 
S corporation shareholders that receive a distributive share or pro 
rata share of any noncash charitable contribution made by a partnership 
or S corporation, regardless of whether the contribution is a qualified 
conservation contribution (and regardless of whether the contribution 
is of real property or other noncash property). These final regulations 
affect partnerships and S corporations that claim qualified 
conservation contributions, and partners and S corporation shareholders 
that receive a distributive share or pro rata share, as applicable, of 
a noncash charitable contribution.

DATES: 
    Effective date: These regulations are effective on June 28, 2024.
    Applicability date: For dates of applicability, see Sec. Sec.  
1.170A-14(o)(1), 1.170A-16(g)(2), 1.706-3(e), and 1.706-4(e)(2)(xiii) 
and (e)(3)(ii).

SUPPLEMENTARY INFORMATION: 

Background

    This document contains final regulations amending the Income Tax 
Regulations (26 CFR part 1) under sections 170 and 706 of the Internal 
Revenue Code (Code) to implement the provisions of section 605(a) and 
(b) of the SECURE 2.0 Act of 2022 (SECURE 2.0 Act), enacted as Division 
T of the Consolidated Appropriations Act, 2023, Public Law 117-328, 136 
Stat. 4459, 5393 (December 29, 2022), which apply to contributions of 
property made after December 29, 2022.

I. Overview of Qualified Conservation Contributions

    Section 170(a) provides, subject to certain limitations and 
requirements, a deduction for any charitable contribution, as defined 
in section 170(c), of cash or other property the payment of which is 
made within the taxable year. Section 170(f) disallows charitable 
contribution deductions in certain cases and provides special rules. 
Section 170(f)(3)(A) provides that, in the case of a contribution (not 
made by a transfer in trust) of an interest in property that consists 
of less than the taxpayer's entire interest in such property, a 
deduction will be allowed only to the extent that the value of the 
interest contributed would be allowable as a deduction under section 
170 if such interest had been transferred in trust. Section 
170(f)(3)(B)(iii) provides that section 170(f)(3)(A) does not apply to 
a qualified conservation contribution.

II. Enactment of Section 170(f)(19) and (h)(7)

    Section 170(h)(7) was added to the Code by section 605(a)(1) of the 
SECURE 2.0 Act. Section 170(h)(7)(A) states that a contribution by a 
partnership (whether directly or as a distributive share of a 
contribution of another partnership) is not treated as a qualified 
conservation contribution for purposes of section 170 if the amount of 
such contribution exceeds 2.5 times the sum of each partner's relevant 
basis in such partnership (Disallowance Rule). Thus, a contribution of 
a qualified real property interest to a qualified organization 
exclusively for conservation purposes is not a qualified conservation 
contribution if the Disallowance Rule applies.
    Section 170(h)(7)(B)(i) provides that, for purposes of section 
170(h)(7), the term ``relevant basis'' means, with respect to any 
partner, the portion of such partner's modified basis in the 
partnership that is allocable (under rules similar to the rules of 
section 755 of the Code) to the portion of the real property with 
respect to which the contribution described in section 170(h)(7)(A) is 
made. Section 170(h)(7)(B)(ii) provides that, for purposes of section 
170(h)(7), the term ``modified basis'' means, with respect to any 
partner, such partner's adjusted basis in the partnership as 
determined: (1) immediately before the contribution described in 
section 170(h)(7)(A), (2) without regard to section 752 of the Code, 
and (3) by the partnership after taking into account these first two 
adjustments and such other adjustments as the Secretary of the Treasury 
or her delegate (Secretary) may provide.
    Section 170(h)(7)(F) provides that the rules of section 170(h)(7) 
``apply to S corporations and other pass-through entities in the same 
manner as such rules apply to partnerships,'' except as the Secretary 
otherwise provides.
    Section 170(h)(7)(C) provides an exception to the Disallowance Rule 
for contributions that satisfy a three-year holding period. Section 
170(h)(7)(D) provides an exception to the Disallowance Rule for 
contributions from family pass-through entities. Section 170(h)(7)(E) 
provides an exception to the Disallowance Rule for qualified 
conservation contributions the conservation purpose of which is the 
preservation of a certified historic structure.
    Section 170(h)(7)(G) provides a specific grant of regulatory 
authority to the Secretary to issue regulations or other guidance as 
the Secretary determines are necessary or appropriate to carry out the 
purposes of the Disallowance Rule, including reporting requirements and 
rules to prevent the avoidance of the Disallowance Rule.
    Section 605(b) of the SECURE 2.0 Act added section 170(f)(19) to 
the Code, which provides that, in the case of a partnership or S 
corporation claiming a qualified conservation contribution for the 
preservation of a building that is a certified historic structure (as 
defined in section 170(h)(4)(C)) in an amount that exceeds 2.5 times 
the sum of each partner's or S corporation shareholder's relevant basis 
(as defined in section 170(h)(7)), no deduction under section 170 is 
allowed unless, as provided in section 170(f)(19)(A)(i) and (ii), the 
partnership or S corporation includes on its return for the taxable 
year a statement that such contribution was

[[Page 54285]]

made and any other information as the Secretary may require. A 
contribution to preserve a certified historic structure is one of the 
three exceptions to the Disallowance Rule.
    Section 605(c) of the SECURE 2.0 Act provides that the amendments 
made by section 605 of the SECURE 2.0 Act apply to contributions made 
after December 29, 2022, and that no inference is intended as to the 
appropriate treatment of contributions made in taxable years ending on 
or before that date, or as to any contribution for which a deduction is 
not disallowed by reason of section 170(h)(7).

III. The Proposed Regulations

    On November 20, 2023, the Department of the Treasury (Treasury 
Department) and the IRS published a notice of proposed rulemaking (REG-
112916-23) (the proposed regulations) in the Federal Register (88 FR 
80910) to provide guidance under section 170(f)(19) and (h)(7). The 
proposed regulations would make changes to existing Sec.  1.170A-14, 
including modifying paragraph (a) to reference the Disallowance Rule 
and adding new paragraphs (j) through (n) to Sec.  1.170A-14 to provide 
guidance on the application of the Disallowance Rule (and its 
exceptions) to partnerships and S corporations. In addition, the 
proposed regulations would make changes to the reporting requirements 
in Sec.  1.170A-16. Finally, the proposed regulations would make 
changes to Sec. Sec.  1.706-3 and 1.706-4 to facilitate the operation 
of the Disallowance Rule in the case of a qualified conservation 
contribution made by a partnership. The provisions of the proposed 
regulations are explained in greater detail in the preamble to the 
proposed regulations.
    Pursuant to section 7805(b)(2) of the Code, regulations issued 
under section 170(f)(19) and (h)(7) within 18 months of the December 
29, 2022, date of enactment of section 605 of the SECURE 2.0 Act are 
permitted to apply to periods ending before the dates provided under 
section 7805(b)(1) (generally, the dates of the issuance of proposed or 
final regulations or a notice describing the regulations). Accordingly, 
the proposed regulations under Sec. Sec.  1.170A-14(j) through (n), 
1.706-3, and 1.706-4 were proposed to apply to contributions made after 
December 29, 2022. To align the reporting requirements under Sec.  
1.170A-16 with the publication of the revised Form 8283, Noncash 
Charitable Contributions, and its instructions, the proposed 
regulations under Sec.  1.170A-16 were proposed to apply to 
contributions made in taxable years ending on or after November 20, 
2023 (the date the proposed regulations were published in the Federal 
Register).

Summary of Comments and Explanation of Revisions

    This Summary of Comments and Explanation of Revisions summarizes 
the proposed regulations and all the substantive comments submitted in 
response to the proposed regulations. The Treasury Department and the 
IRS received eight written comments in response to the proposed 
regulations. The comments are available for public inspection at 
https://www.regulations.gov or upon request. There were no requests to 
speak at the scheduled public hearing. Consequently, the public hearing 
was cancelled (89 FR 39). After full consideration of the comments 
received, these final regulations adopt the proposed regulations with 
modifications as described in this Summary of Comments and Explanation 
of Revisions.
    The comments can be grouped into the following categories: (1) 
definitions, (2) the computation of relevant basis, (3) requests for 
guidance under the partnership allocation rules, (4) the exceptions to 
the Disallowance Rule, (5) reporting requirements, and (6) other 
comments. Each category is discussed in turn in the remainder of this 
Summary of Comments and Explanation of Revisions.

I. Definitions

    Proposed Sec.  1.170A-14(j)(3) contained definitions of terms, 
including ``allocated portion,'' ``amount of qualified conservation 
contribution,'' ``contributing partnership,'' ``contributing S 
corporation,'' ``direct interest,'' ``directly,'' ``disallowed 
qualified conservation contribution,'' ``indirect interest,'' 
``indirectly,'' ``ultimate member,'' ``upper-tier partnership,'' and 
``upper-tier S corporation.'' Commenters generally provided no comments 
on these definitions, except with respect to the definition of the 
amount of qualified conservation contribution. Thus, the final 
regulations adopt the definitions as proposed, except with respect to 
the definition of the amount of qualified conservation contribution.
    Proposed Sec.  1.170A-14(j)(3)(ii) defined ``amount of qualified 
conservation contribution'' as the amount claimed as a qualified 
conservation contribution on the return of the contributing partnership 
or contributing S corporation for the taxable year in which the 
contribution is made. No comments addressed the first sentence of 
proposed Sec.  1.170A-14(j)(3)(ii), so the final regulations adopt that 
sentence as proposed.
    Proposed Sec.  1.170A-14(j)(3)(ii) further provided, ``[i]f the 
contributing partnership or contributing S corporation files an amended 
return or administrative adjustment request under section 6227 of the 
Code claiming a different amount with respect to the qualified 
conservation contribution, the rules of [Sec.  1.170A-14] must be re-
applied with respect to such different amount to determine the 
application of section 170(h)(7) and [Sec.  1.170A-14.]'' One commenter 
stated that this sentence would seem to inappropriately allow 
partnerships or S corporations to file administrative adjustment 
requests or amended returns after they had been notified of an IRS 
examination. The commenter recommended that the regulations be changed 
to refer only to an amended return or administrative adjustment request 
that is a ``qualified amended return'' for purposes of the substantial 
underpayment rules.
    The Treasury Department and the IRS understand the commenter's 
reference to ``qualified amended return'' to be a reference to Sec.  
1.6664-2(c)(3). Under Sec.  1.6664-2(c)(3), a qualified amended return 
is an amended return or a timely request for an administrative 
adjustment under section 6227, filed after the due date of the return 
for the taxable year and before the earliest of several dates, 
including the date the taxpayer is first contacted by the IRS 
concerning any examination with respect to the return. Under section 
6227(a), a partnership may file an administrative adjustment request 
for the amount of a partnership-related item for any partnership 
taxable year. However, under section 6227(c), a partnership may not 
file an administrative adjustment request after a notice of an 
administrative proceeding with respect to the taxable year is mailed 
under section 6231 of the Code.
    The Treasury Department and the IRS did not intend the proposed 
regulations to allow for the filing of an amended return or 
administrative adjustment request in situations in which the 
partnership or S corporation would not otherwise be allowed to file an 
amended return or administrative adjustment request. Moreover, the 
Treasury Department and the IRS agree that the re-application provision 
in Sec.  1.170A-14(j)(3)(ii) should not be understood to allow a 
partnership or S corporation to avoid the Disallowance Rule by filing 
an amended return or administrative adjustment request claiming a lower 
amount with respect to a qualified conservation contribution after 
being contacted by the IRS concerning an

[[Page 54286]]

examination regarding the return. For example, under an inappropriate 
interpretation of the language in the proposed regulations, a 
contributing S corporation could violate the Disallowance Rule by 
claiming an amount of a qualified conservation contribution on its 
original return that exceeds 2.5 times the sum of the relevant bases. 
Then, after its return has been selected for examination by the IRS, 
the contributing S corporation could attempt to file an amended return 
on which it reduces the amount of its claimed qualified conservation 
contribution to an amount not exceeding 2.5 times the sum of the 
relevant bases. The contributing S corporation could then argue that 
the re-application provision in Sec.  1.170A-14(j)(3)(ii) allows the 
Disallowance Rule to be re-tested, and that, therefore, its qualified 
conservation contribution is not disallowed, but instead is allowed to 
the extent of the amount claimed on the amended return. In order to 
balance the need for a mechanism to timely fix errors made in good-
faith with the risk of circumvention of the Disallowance Rule, these 
final regulations limit the re-application provision by providing that, 
if the contributing partnership or contributing S corporation files an 
amended return or timely administrative adjustment request under 
section 6227 of the Code claiming a lower amount with respect to the 
qualified conservation contribution, the rules of Sec.  1.170A-14 will 
be re-applied with respect to such lower amount to determine the 
application of section 170(h)(7) and Sec.  1.170A-14 if and only if the 
amended return or timely administrative adjustment request is filed 
before the contributing partnership or contributing S corporation is 
put on notice of an IRS examination relating to the qualified 
conservation contribution. The final regulations provide that a 
contributing partnership or contributing S corporation is considered to 
be on notice after the earlier of: (1) the date the contributing 
partnership or contributing S corporation is first contacted by the IRS 
in connection with any examination of a return that relates to the 
qualified conservation contribution, or (2) the date any person is 
first contacted by the IRS concerning an examination of that person 
under section 6700 (relating to the penalty for promoting abusive tax 
shelters) for an activity that relates to the qualified conservation 
contribution. These regulations do not incorporate the full definition 
of qualified amended returns within the meaning of Sec.  1.6664-2(c)(3) 
as requested by the commenter, because a definition tailored to the 
context of this regulation is sufficient to prevent abusive 
circumventions of the Disallowance Rule without being overbroad and 
preventing a contributing partnership or contributing S corporation 
from being able to use the re-application provision in non-abusive 
situations.
    In addition, the Treasury Department and the IRS remain concerned 
about situations in which a contributing partnership or contributing S 
corporation files an amended return or administrative adjustment 
request that claims a higher amount with respect to a qualified 
conservation contribution. In that situation, the Treasury Department 
and the IRS have concluded that the rules of Sec.  1.170A-14 should be 
re-applied with respect to such higher amount to determine the 
application of section 170(h)(7) and Sec.  1.170A-14 regardless of 
whether the amended return or administrative adjustment request 
constitutes a qualified amended return. This rule is necessary to 
ensure that the Disallowance Rule is not avoided simply by filing an 
original return claiming an amount with respect to a qualified 
conservation contribution that does not exceed 2.5 times the sum of the 
relevant bases, followed by an amended return or administrative 
adjustment request claiming an amount with respect to the qualified 
conservation contribution that does exceed 2.5 times the sum of the 
relevant bases. Accordingly, these final regulations modify the second 
sentence of Sec.  1.170A-14(j)(3)(ii) to clarify that, if the 
contributing partnership or contributing S corporation files an amended 
return or administrative adjustment request under section 6227 of the 
Code claiming a higher amount with respect to the qualified 
conservation contribution, the rules of Sec.  1.170A-14 must be re-
applied with respect to such higher amount to determine the application 
of section 170(h)(7) and Sec.  1.170A-14; for example, if a 
contributing S corporation's original return claims a qualified 
conservation contribution that does not exceed 2.5 times the sum of the 
relevant bases, and the S corporation subsequently files an amended 
return claiming a higher amount with respect to the qualified 
conservation contribution that does exceed 2.5 times the sum of the 
relevant bases, then the entire amount of the qualified conservation 
contribution is a disallowed qualified conservation contribution 
(unless one of the exceptions in Sec.  1.170A-14(n) applies).

II. Computation of Relevant Basis

    As noted earlier, section 170(h)(7)(B)(i) provides that, for 
purposes of section 170(h)(7), the term ``relevant basis'' means, with 
respect to any partner, the portion of such partner's modified basis in 
the partnership that is allocable (under rules similar to the rules of 
section 755 of the Code) to the portion of the real property with 
respect to which the contribution described in section 170(h)(7)(A) is 
made. Proposed Sec.  1.170A-14(l) provided guidance on the 
determination of modified basis. Proposed Sec.  1.170A-14(m) provided 
guidance on the allocation of modified basis, which results in the 
determination of relevant basis.
    The Treasury Department and the IRS received several comments on 
the computation of modified basis and relevant basis, which can be 
divided into the following two topics: (1) the determination of 
modified basis, and (2) the allocation of modified basis to determine 
relevant basis.
A. Determination of Modified Basis
    As noted earlier, section 170(h)(7)(B)(ii) provides that, for 
purposes of section 170(h)(7), the term ``modified basis'' means, with 
respect to any partner, such partner's adjusted basis in the 
partnership as determined: (1) immediately before the contribution 
described in section 170(h)(7)(A), (2) without regard to section 752, 
and (3) by the partnership after taking into account those adjustments 
and such other adjustments as the Secretary may provide. Section 
170(h)(7)(F) provides that the rules of section 170(h)(7) ``apply to S 
corporations and other pass-through entities in the same manner as such 
rules apply to partnerships'' except as the Secretary may otherwise 
provide. This section of the preamble discusses: (1) the proposed 
regulations, comments, and final regulations for the determination of a 
partner's modified basis, and (2) the proposed regulations, comments, 
and final regulations for the determination of an S corporation 
shareholder's modified basis.
1. Determination of a Partner's Modified Basis
a. Proposed Rules for the Determination of a Partner's Modified Basis
    Proposed Sec.  1.170A-14(l)(2)(i) defined the term ``modified 
basis'' to mean, with respect to any ultimate member that is a direct 
partner in either a contributing partnership or an upper-tier 
partnership, such ultimate member's adjusted basis in its interest in 
the partnership in which the ultimate

[[Page 54287]]

member holds a direct interest as of the beginning of the first day of 
the partnership's taxable year in which the qualified conservation 
contribution is made, with adjustments as determined under proposed 
Sec.  1.170A-14(l)(2)(ii) through (v). However, if the ultimate member 
was not a partner as of the beginning of the first day of the 
partnership's taxable year in which the qualified conservation 
contribution is made, then the term ``modified basis'' means such 
ultimate member's adjusted basis in its interest in the partnership 
immediately after the transaction that resulted in the ultimate member 
becoming a partner, with adjustments as determined under proposed Sec.  
1.170A-14(l)(2)(ii) through (v).
    The proposed regulations provided that the following four 
adjustments must be made in the order in which they are listed. First, 
proposed Sec.  1.170A-14(l)(2)(ii) required an increase for any 
contributions made by the ultimate member to the partnership during the 
portion of the year commencing with the beginning of the taxable year 
of the partnership and ending immediately prior to the time of day at 
which the qualified conservation contribution is made as provided in 
section 722 of the Code.
    Second, proposed Sec.  1.170A-14(l)(2)(iii) required an adjustment, 
as provided in section 705 of the Code, by the ultimate member's 
hypothetical distributive share of partnership items attributable to 
the portion of the year commencing with the beginning of the taxable 
year of the partnership and ending immediately prior to the time of day 
at which the qualified conservation contribution is made. In making 
this determination, the partnership would be required to apply the 
rules of Sec.  1.706-4 and apply a hypothetical interim closing method 
to allocate the partnership's items attributable to the portion of the 
year commencing with the beginning of the taxable year of the 
partnership and ending immediately prior to the time of day at which 
the qualified conservation contribution is made. The proposed 
regulations provided that the partnership cannot apply any convention 
in Sec.  1.706-4(c) to the hypothetical determination of the partners' 
distributive shares, but rather must perform the calculation as though 
the determination occurred immediately prior to the time of day at 
which the qualified conservation contribution is made. The proposed 
regulations clarified that this hypothetical determination of the 
partners' distributive shares is only for purposes of calculating 
modified basis. Proposed Sec.  1.170A-14(l)(2)(iii) did not require the 
partnership to use the interim closing method with respect to the 
determination of its partners' actual distributive shares of 
partnership items of income, gain, loss, deduction, and credit for the 
taxable year in which the qualified conservation contribution is made 
or otherwise.
    Third, proposed Sec.  1.170A-14(l)(2)(iv) required a reduction (but 
not below zero) for any distributions made by the partnership to the 
ultimate member during the portion of the year commencing with the 
beginning of the taxable year of the partnership and ending immediately 
prior to the time of day at which the qualified conservation 
contribution is made as provided in section 733 of the Code.
    Fourth, proposed Sec.  1.170A-14(l)(2)(v) required a reduction for 
the full amount of the ultimate member's share of Sec.  1.752-1 
liabilities of any partnership (including a lower-tier partnership). 
The remaining amount would be such ultimate member's modified basis.
    The proposed regulations contained two examples illustrating these 
rules.
b. Comments Concerning a Partner's Modified Basis
    The comments on the determination of modified basis can be grouped 
into the following three categories: (1) inclusion of section 752 
liabilities in modified basis, (2) determining modified basis 
immediately prior to the qualified conservation contribution, and (3) 
the complexity of the computations.
i. Inclusion of Section 752 Liabilities in Modified Basis
    Section 170(h)(7)(B)(ii)(II) provides that modified basis is 
determined without regard to section 752. Section 752(a) provides that 
any increase in a partner's share of the liabilities of a partnership, 
or any increase in a partner's individual liabilities by reason of the 
assumption by such partner of partnership liabilities, is considered as 
a contribution of money by such partner to the partnership. Section 
752(b) provides that any decrease in a partner's share of the 
liabilities of a partnership, or any decrease in a partner's individual 
liabilities by reason of the assumption by the partnership of such 
individual liabilities, is considered as a distribution of money to the 
partner by the partnership. Existing Sec.  1.752-1 provides guidance 
under section 752, including a definition of liabilities. Generally, 
under the rules of subchapter K of chapter 1 of the Code (subchapter 
K), if a partnership borrows money, the aggregate bases of its 
partners' interests in the partnership will increase by the amount of 
the borrowing. Consistent with section 170(h)(7)(B)(ii)(II), proposed 
Sec.  1.170A-14(l)(2)(v) required subtracting the full amount of the 
partner's share of Sec.  1.752-1 liabilities of any partnership 
(including a lower-tier partnership) for purposes of calculating 
modified basis.
    One commenter expressed concern that the relevant basis calculation 
ignores section 752 liabilities generally. The commenter offered an 
example of a partnership with $200,000 in cash that borrows an 
additional $800,000 and purchases a building for $1,000,000. The 
commenter stated that the proposed regulations would ignore the 
$800,000 as a section 752 liability and that any conservation 
contribution for historic preservation of the building would be capped 
at $500,000.
    Section 170(h)(7)(B)(ii)(II) provides that a partner's modified 
basis (and thus, relevant basis) is determined without regard to 
section 752. The approach in the proposed regulations appropriately 
effectuates this statutory directive. Thus, in the commenter's example, 
although the partnership's $800,000 liability will increase the 
partners' aggregate bases in their partnership interests by $800,000, 
none of that $800,000 will be reflected in any partner's modified basis 
or relevant basis.
    The commenter's assumption that the Disallowance Rule would cap the 
amount of the partnership's qualified conservation contribution at 
$500,000 misunderstands the rule. Several other considerations must be 
taken into account to determine the extent of any allowable qualified 
conservation contribution. First, the Disallowance Rule is not a cap--
as explained in the preamble to the proposed regulations and as 
provided in proposed Sec.  1.170A-14(j)(1), if the amount of a 
qualified conservation contribution claimed by a partnership or an S 
corporation exceeds 2.5 times the sum of the relevant bases, no 
deduction is allowed at all for the contribution unless one of the 
three statutory exceptions applies. Second, application of the 
Disallowance Rule is not based on the difference between the amount of 
the contribution and the partnership's basis in the donated property; 
it is based on whether the contribution exceeds 2.5 times the sum of 
the ultimate members' relevant bases. The facts presented in the 
commenter's example are insufficient to determine whether 2.5 times the 
sum of the relevant bases is $500,000.\1\
---------------------------------------------------------------------------

    \1\ Moreover, the commenter's example seems to involve a 
qualified conservation contribution the conservation purpose of 
which is the preservation of a historic structure. If so, the 
Disallowance Rule would not apply under section 170(h)(7)(E) and 
proposed Sec.  1.170A-14(n)(4), provided that, if the amount of the 
contribution exceeds 2.5 times the sum of the relevant bases, the 
partnership or S corporation complies with the reporting 
requirements of section 170(f)(19) and proposed Sec.  1.170A-
16(f)(6).

---------------------------------------------------------------------------

[[Page 54288]]

    The same commenter also expressed concerns that the proposed 
regulations appear to treat the ultimate member's share of liabilities 
under Sec.  1.752-1(b) as ``flowing only in one direction'' because the 
proposed regulations provided that modified basis must be reduced by 
the full amount of the ultimate member's share of Sec.  1.752-1 
liabilities of any partnership. The commenter stated that this language 
ignores that a partner's share of liabilities may increase the 
partner's basis.
    It is true that a partner's share of the partnership's liabilities 
increases the partner's basis in its interest in the partnership. 
However, this basis is not included for purposes of the Disallowance 
Rule pursuant to section 170(h)(7)(B)(ii)(II), which requires modified 
basis to be determined without regard to a partner's share of the 
partnership's liabilities. Thus, these regulations finalize Sec.  
1.170A-14(l)(2)(v) without change.
ii. Determining Modified Basis Immediately Prior to the Qualified 
Conservation Contribution
    One commenter stated that the proposed regulations appear to time 
the calculation of modified basis as of the time of the qualified 
conservation contribution. The commenter stated that this ``artificial 
cutoff'' ignores any basis allocable to the ultimate members following 
the contribution, such as from capital contributions or increases in 
the ultimate members' share of section 752 liabilities.
    The Treasury Department and the IRS confirm that the rules in the 
proposed regulations require the calculation of modified basis (and 
thus, relevant basis) as of the time of the qualified conservation 
contribution. As explained earlier, the proposed regulations were 
intended to effectuate section 170(h)(7)(B)(ii)(I), which provides that 
modified basis is the partner's adjusted basis in the partnership as 
determined ``immediately before'' the qualified conservation 
contribution. The Treasury Department and the IRS do not agree with the 
commenter's suggestion that modified basis include amounts that were 
reflected in the ultimate member's adjusted basis in its interest in 
the partnership only after the contribution because inclusion of such 
amounts would contradict the statute. Thus, the proposed regulations 
are adopted without change as to this issue.
    As a clarification to the statutory rule that modified basis is 
determined immediately before a qualified conservation contribution is 
made, the final regulations add a new step to the list of steps in 
proposed Sec.  1.170A-14(l)(2). As described in the preamble to the 
proposed regulations, the proposed regulations were designed to 
facilitate the computation of a partner's ``adjusted basis'' in its 
partnership interest immediately prior to the qualified conservation 
contribution. As also described in the preamble to the proposed 
regulations, adjusted basis is typically computed as of the beginning 
or end of a taxable year, and generally, not as of the time of a 
particular event, such as the making of a qualified conservation 
contribution. Accordingly, the approach in the proposed regulations 
started with a calculation of adjusted basis that partners are familiar 
with computing, and then made adjustments designed to arrive at an 
amount that reflects the partner's adjusted basis immediately before 
the qualified conservation contribution. The proposed regulations did 
not, however, take into account acquisitions of additional partnership 
interests or partial dispositions of partnership interests that 
occurred after the beginning of the taxable year and prior to the 
qualified conservation contribution. In those situations, an additional 
step is necessary to effectuate the rule in section 170(h)(7)(B)(ii) 
that modified basis is adjusted basis immediately before the qualified 
conservation contribution without regard to section 752. The new step, 
in Sec.  1.170A-14(l)(2)(iii), provides that if, between the beginning 
of the partnership's taxable year and the time of day at which the 
qualified conservation contribution is made, the ultimate member 
acquired additional interests in the partnership, modified basis must 
be increased by the ultimate member's initial basis in those additional 
interests. Similarly, Sec.  1.170A-14(l)(2)(iii) provides that if, 
between the beginning of the partnership's taxable year and the time of 
day at which the qualified conservation contribution is made, the 
ultimate member partially disposed of its interest in the partnership, 
modified basis must be decreased by the ultimate member's basis in the 
interests disposed of. The final regulations add Sec.  1.170A-
14(l)(4)(iv) (Example 4) to illustrate this step.
iii. Complexity of the Determination of Modified Basis
    Multiple commenters stated that the proposed regulations' 
calculations, including the calculation of modified basis, were too 
complex.\2\ One commenter stated that the proposed regulations are well 
drafted and that the mechanical rules work, but that the computations 
are too complex. Another commenter stated that the calculations were 
complex and would be difficult for taxpayers, land trusts, and even the 
IRS to administer. Another commenter stated that the proposed rules are 
unnecessarily complex and will likely discourage many partnerships from 
making conservation contributions even if, after performing the 
calculations, the contribution would not be disallowed by the 
Disallowance Rule. Finally, another commenter found the regulations to 
be a ``complex labyrinth'' in which one misstep leads to the 
disallowance of the charitable deduction and imposition of the gross 
overvaluation penalty under section 6662(h) and also places a 
significant burden on the IRS and the Independent Office of Appeals. 
This commenter suggested that, under Executive Order 12866, 58 FR 190 
(October 4, 1993), and Internal Revenue Manual provision 
32.1.4.1.1(1)(a), the Treasury Department and the IRS are required to 
draft regulations to minimize litigation, but that the proposed 
regulations likely will increase litigation as the regulations are 
overly complex and burdensome for the average taxpayer.
---------------------------------------------------------------------------

    \2\ It is unclear from the comments whether some commenters were 
objecting to the complexity of the determination of modified basis, 
the determination of relevant basis (once modified basis is 
determined), or both. Comments addressing the complexity of 
determining relative basis once modified basis is determined are 
discussed in Parts II.B.1.a, II.B.2, II.B.3.a, and II.B.4.a of this 
Summary of Comments and Explanation of Revisions.
---------------------------------------------------------------------------

    As an alternative to the complexity in the proposed regulations, 
one commenter suggested that the IRS develop simplified safe harbor 
calculations. Another commenter suggested applying pure aggregate rules 
to the contributing partnership and any upper-tier partnerships to 
determine modified basis and relevant basis and adding an anti-abuse 
rule that the transaction does not work if a principal purpose is to 
avoid the limitations of section 170(h)(7). This commenter noted, 
however, that this suggestion was less precise and subject to potential 
abuse, but stated that it is a rule that even small practitioners could 
apply.
    These suggested approaches are not specific or accurate enough to 
comply with the statutory directive of section

[[Page 54289]]

170(h)(7). Section 170(h)(7)(B)(ii)(I) through (III) provides that 
modified basis is the partner's adjusted basis in the partnership 
immediately before the qualified conservation contribution, without 
regard to section 752. Partners generally do not track their bases in 
their partnership interests on a daily basis. Instead, such 
determinations are typically made at year end. Thus, a partnership 
generally will not know each partner's basis in its partnership 
interest as of a particular point during the year, such as the moment 
at which the partnership makes a qualified conservation contribution. A 
partnership required by section 170(h)(7)(B)(ii)(III) to compute 
modified basis would generally have to start with each partner's 
adjusted basis in its partnership interest as of the beginning of the 
year \3\ and make certain adjustments for items or events occurring in 
the portion of the year ending with the qualified conservation 
contribution that affect basis. These are the very steps that were 
prescribed by the proposed regulations. Each of the steps from the 
proposed regulations is necessary to carry out the statutory directive 
that a partner's modified basis is the partner's adjusted basis in its 
partnership interest immediately before the time of the qualified 
conservation contribution, as computed by the partnership, and without 
regard to section 752 liabilities. Instead of simply repeating the 
statutory mandate, the proposed regulations provided a clear, 
administrable, step-by-step approach for taxpayers to reach the result 
required by the statute. To assist with performing the computations 
required by this step-by-step approach, the proposed regulations 
included several illustrative examples. Accordingly, proposed Sec.  
1.170A-14(l)(2) is finalized with the changes described in this Part 
II.A.1 of this Summary of Comments and Explanation of Revisions.
---------------------------------------------------------------------------

    \3\ In the case of a partner who was not a partner at the 
beginning of the year, but acquired an interest sometime later, the 
partnership would generally have to start with the partner's 
adjusted basis in its partnership interest as of the time of the 
acquisition of that interest. This is the process that these 
regulations provide.
---------------------------------------------------------------------------

2. Determination of an S Corporation Shareholder's Modified Basis
a. Proposed Rules for the Determination of an S Corporation 
Shareholder's Modified Basis
    Proposed Sec.  1.170A-14(l)(3)(i) provided that the term ``modified 
basis'' means, with respect to any ultimate member that is a 
shareholder in an S corporation, such ultimate member's adjusted basis 
in its shares in the S corporation as of the end of the S corporation's 
taxable year in which the qualified conservation contribution is made 
with adjustments as determined under proposed Sec.  1.170A-14(l)(3)(ii) 
and (iii). However, if the ultimate member was not a shareholder at the 
end of the S corporation's taxable year in which the qualified 
conservation contribution is made, then the term ``modified basis'' was 
defined to mean such ultimate member's adjusted basis in its shares in 
the S corporation immediately prior to the transaction that terminated 
its interest in the S corporation, with adjustments as determined under 
proposed Sec.  1.170A-14(l)(3)(ii) and (iii). Consistent with the 
exclusion of section 752 liabilities under section 
170(h)(7)(B)(ii)(II), proposed Sec.  1.170A-14(l)(3)(i) clarified that 
modified basis does not include the ultimate member's adjusted basis in 
any indebtedness of the S corporation to the ultimate member.
    Because the calculation of modified basis for an S corporation 
begins at the end of the year, proposed Sec.  1.170A-14(l)(3)(ii) 
required the computation of modified basis to be increased by the 
amount of any decrease to the adjusted basis as a result of the 
qualified conservation contribution. Thus, the ultimate member's 
modified basis with respect to a qualified conservation contribution 
would not reflect any reduction for the ultimate member's pro rata 
share of the S corporation's basis in the conservation easement or 
other property contributed in the qualified conservation contribution.
    Proposed Sec.  1.170A-14(l)(3)(iii) provided that the amount 
determined under Sec.  1.170A-14(l)(3)(ii) must be multiplied by the 
number of days during the S corporation's taxable year in which the 
ultimate member was a shareholder and divided by the total number of 
days during the S corporation's taxable year. The resulting amount 
would be such ultimate member's modified basis.
    The proposed regulations contained an example illustrating these 
rules.
b. Comments Concerning Modified Basis for S Corporation Shareholders
    Commenters did not provide specific comments concerning the rules 
for S corporation shareholders; however, as described in Part II.A.1.b 
of this Summary of Comments and Explanation of Revisions, certain 
commenters discussed complexity concerns with respect to modified basis 
without specifically identifying partnerships, so those comments may 
also apply to S corporations. The Treasury Department and the IRS have 
determined that the rules for determining modified basis for S 
corporation shareholders are not unduly complex. In particular, any of 
the information required to determine modified basis should be readily 
known by a contributing S corporation and its ultimate members. The 
regulations provide clear, administrable rules that are illustrated 
with computational examples. This clarity will help decrease disputes 
about the computation of modified basis. Accordingly, these final 
regulations do not make changes to the rules for the determination of 
modified basis in response to the commenters' concerns about complexity 
and proposed Sec.  1.170A-14(l)(3) is finalized without change.

B. Allocation of Modified Basis To Determine Relevant Basis

    Proposed Sec.  1.170A-14(m) provided rules for determining relevant 
basis, which is the portion of modified basis that is allocable to the 
portion of the real property with respect to which the qualified 
conservation contribution is made. In general, the proposed regulations 
provided that relevant basis is modified basis multiplied by a 
fraction, the numerator of which is the ultimate member's portion of 
the basis in the real property with respect to which the qualified 
conservation contribution is made, and the denominator of which is the 
ultimate member's portion of the basis in all properties held by the 
partnership or S corporation. For example, if an ultimate member's 
share of the basis in the real property is half of the ultimate 
member's share of the basis in the other properties of the partnership 
or S corporation, the ultimate member's relevant basis would be half of 
the ultimate member's modified basis. The proposed regulations 
contained rules for these computations, including rules for the 
computation of relevant basis in tiered entities. The proposed 
regulations also contained additional details and several examples of 
the computation of relevant basis.
    The proposed regulations provided separate rules for the 
determination of relevant basis for ultimate members who are: (1) 
partners in contributing partnerships, (2) shareholders in contributing 
S corporations, (3) partners in upper-tier partnerships, and (4) 
shareholders in upper-tier S corporations. The following portion of 
this Summary of Comments and Explanation of Revisions will discuss each 
set of rules in turn.

[[Page 54290]]

1. Determination of Relevant Basis for Partners in Contributing 
Partnerships
    Proposed Sec.  1.170A-14(m)(2)(i) through (iii) provided that the 
relevant basis of an ultimate member holding a direct interest in a 
contributing partnership is equal to the ultimate member's modified 
basis as determined under proposed Sec.  1.170A-14(l)(2) multiplied by 
a fraction: (1) the numerator of which is the ultimate member's share 
of the contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made as determined under proposed Sec.  1.170A-
14(m)(2)(ii); and (2) the denominator of which is the ultimate member's 
portion of the adjusted basis in all the contributing partnership's 
properties as determined under proposed Sec.  1.170A-14(m)(2)(iii).
    For purposes of this computation, proposed Sec.  1.170A-
14(m)(2)(ii) provided that an ultimate member's share of the 
contributing partnership's adjusted basis in the portion of the real 
property with respect to which the qualified conservation contribution 
is made equals the contributing partnership's adjusted basis in the 
portion of the real property with respect to which the qualified 
conservation contribution is made (determined as of the time of day of 
the contribution) multiplied by a fraction: (1) the numerator of which 
is the ultimate member's distributive share of the qualified 
conservation contribution; and (2) the denominator of which is the 
total amount of the contributing partnership's qualified conservation 
contribution.
    Proposed Sec.  1.170A-14(m)(2)(iii) provided that an ultimate 
member's portion of the adjusted basis in all the contributing 
partnership's properties is equal to the sum of: (1) the ultimate 
member's share of the contributing partnership's adjusted basis in the 
portion of the real property with respect to which the qualified 
conservation contribution is made as determined under proposed Sec.  
1.170A-14(m)(2)(ii), and (2) the ultimate member's portion of the 
adjusted basis in all the contributing partnership's properties other 
than the portion of the real property with respect to which the 
qualified conservation contribution is made. To determine an ultimate 
member's share of the adjusted basis in all the contributing 
partnership's properties, the proposed regulations provided that a 
contributing partnership must apportion among each of its partners in 
accordance with their interests in the partnership under section 704(b) 
of the Code the partnership's adjusted basis in each of its properties 
(except the portion of the real property with respect to which the 
qualified conservation contribution is made), using the adjusted bases 
immediately before the qualified conservation contribution, without 
duplication or omission of any property, and by treating the adjusted 
basis in each property as not less than zero.
    Proposed Sec.  1.170A-14(m)(2)(iv) provided the following formula 
incorporating these rules:

R = M x (T / (D + T))

Where:

R = Relevant basis.
M = Modified basis as determined under proposed Sec.  1.170A-14(l).
D = Ultimate member's portion of the adjusted basis in all the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made), determined by apportioning among the partners 
of the contributing partnership in accordance with their interests 
in the partnership under section 704(b) its adjusted basis in each 
of its properties (other than the portion of the real property with 
respect to which the qualified conservation contribution is made), 
using the adjusted bases immediately before the qualified 
conservation contribution, without duplication or omission of any 
property, and by treating the adjusted basis in each property as not 
less than zero.
T = Ultimate member's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made, determined 
according to the following formula: A x (B / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
B = Ultimate member's distributive share of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    The comments received on the allocation of modified basis can be 
grouped into the following two categories: (a) complexity, and (b) the 
effect of section 704(c) property. Each category is discussed in turn.
a. Complexity of the Proposed Rules for the Allocation of Modified 
Basis
    As noted in Part II.A.1.b.iii. of this Summary of Comments and 
Explanation of Revisions, multiple commenters stated that the 
calculations in the proposed regulations were too complex. One 
commenter stated that the Treasury Department and the IRS should 
reconsider the computational proposals and develop ``simplified safe 
harbor calculations'' to give taxpayers the assurance that they have 
done the math correctly and will not unintentionally incur additional 
tax and significant penalties. As mentioned previously, one commenter 
who objected to the complexity of the calculations proposed an 
alternative method of applying pure aggregate rules to the contributing 
partnership and any upper-tier partnerships to determine modified basis 
and relevant basis. The commenter described this alternative as 
``simple'' and suggested adding an anti-abuse rule if a principal 
purpose is to avoid the limitations of section 170(h)(7), but also 
acknowledged that this approach was ``[l]ess precise and subject to 
potential abuse.'' Other commenters, while stating that the proposed 
regulations were complex, did not express any alternative suggestions.
    The rules in the proposed regulations for the allocation of 
modified basis to determine relevant basis are not inappropriately 
complex in light of the statute which they administer. Section 
170(h)(7)(B)(i) directs that modified basis be allocated to the portion 
of the real property with respect to which the qualified conservation 
contribution is made under rules similar to the rules of section 755. 
As mentioned in the preamble to the proposed regulations, the section 
755 regulations involve several different methods for allocating basis 
adjustments among the partnership's properties, including allocating in 
proportion to the partner's share of the adjusted bases in the 
partnership's properties. See Sec.  1.755-1(b)(5)(iii)(B). The section 
755 regulations contain mathematical examples illustrating these rules, 
formulas, and computations and also additional rules and exceptions.
    As explained in the preamble to the proposed regulations, the 
Treasury Department and the IRS considered simply cross-referencing the 
rules under section 755. However, allocations under section 755 are 
sometimes made in a way to reduce or eliminate built-in gain or built-
in loss in partnership property. The relevant basis rule of section 
170(h)(7)(B)(i) is designed to determine the portion of a partner's 
modified basis that is allocable to the portion of the real property 
with respect to which the contribution is made, which is a broader and, 
generally, different concept than determining the partner's share of 
built-in gain or built-in loss in that property. Thus, applying an 
approach based solely on the existing section 755 regulations would not 
be consistent with the purpose of the Disallowance Rule. Moreover, 
these regulations for the allocation of modified basis are similar

[[Page 54291]]

to, and not more complex than, the rules of section 755.
    Section 170(h)(7) is computational in nature. Although the statute 
is relatively short and does not list any formulas, complying with 
section 170(h)(7)(B)(i) necessarily involves computations involving 
every asset owned by the partnership or S corporation and any lower-
tier partnerships. The proposed regulations acknowledged this 
complexity and, if possible, sought to simplify the requirements and 
provide clear guidance. Thus, the proposed regulations are not more 
complex than the statutory language already requires.
    Furthermore, partnerships and S corporations making qualified 
conservation contributions are required by existing rules to track each 
partner's and shareholder's share of the entity's basis in the 
contributed property. See sections 704(d)(3), 705(a)(2), 1366(d)(4), 
and 1367(a)(2) of the Code; Rev. Rul. 96-11, 1996-1 C.B. 140; Rev. Rul. 
2008-16, 2008-1 C.B. 585. Additionally, in certain circumstances the 
rules under section 755 require a partnership to calculate a partner's 
share of the partnership's basis in its properties. Thus, the approach 
taken by the proposed regulations is consistent with existing rules and 
principles.
    The Treasury Department and the IRS have considered the commenter's 
recommendation of determining relevant basis based on a ``pure 
aggregate'' approach, subject to an anti-abuse rule or some type of 
safe harbor. The Treasury Department and the IRS agree with the 
commenter's assessment that such an approach would be less clear and 
more subject to abuse. As explained in the preamble to the proposed 
regulations, Congress enacted the Disallowance Rule because of abusive 
syndicated conservation easement transactions. It would not be 
appropriate to deviate from the computational requirements of the 
statute. Congress intended that partnerships and S corporations that 
make qualified conservation contributions perform several calculations 
to substantiate that the contribution is not disallowed by the 
Disallowance Rule. Allowing for shortcuts to such calculations that 
lead to less accurate results would be inconsistent with Congress's 
purpose in enacting the Disallowance Rule. Moreover, the computational 
step-by-step approach in the proposed regulations will minimize 
litigation by providing clear, administrable guidance. A shorter, more 
conceptually-based rule such as ``safe harbor'' calculations or ``pure 
aggregate treatment'' would be less clear and would lead to additional 
disputes over the proper computation of relevant basis.
    In sum, the Treasury Department and the IRS have determined that 
the approach in the proposed regulations is similar to the rules of 
section 755, consistent with the rule of section 170(h)(7)(B)(i), and 
consistent with the purposes of the Disallowance Rule. Accordingly, the 
Treasury Department and the IRS do not adopt the approaches suggested 
by commenters.
b. Effect of Section 704(c) on the Allocation of Modified Basis
    As noted earlier, the proposed regulations allocate modified basis 
by reference, in part, to the partners' interests in the partnership, 
which is a concept under section 704(b). Specifically, under proposed 
Sec.  1.170A-14(m)(2)(iii)(B), to determine a partner's portion of the 
adjusted basis in all the contributing partnership's properties, the 
contributing partnership would apportion among its partners in 
accordance with their interests in the partnership under section 704(b) 
its adjusted basis in each of its properties (except the portion of the 
real property with respect to which the qualified conservation 
contribution is made), using the adjusted bases immediately before the 
qualified conservation contribution, without duplication or omission of 
any property, and by treating the adjusted basis in each property as 
not less than zero.
    The proposed regulations did not explicitly address the impact of 
section 704(c) amounts. One commenter stated that, to promote 
transparency, the final regulations should discuss what impact, if any, 
section 704(c) may have with respect to conservation easement 
transactions in the context of section 170(h)(7).
    In part, section 704(c) provides rules for partnership allocations 
with respect to property that has built-in gain (that is, fair market 
value in excess of adjusted basis) or built-in loss (that is, adjusted 
basis in excess of fair market value) at the time the property is 
contributed by a partner to the partnership (section 704(c) property). 
Section 704(c)(1)(A) provides that, under regulations prescribed by the 
Secretary, income, gain, loss, and deduction with respect to property 
contributed to the partnership by a partner is shared among the 
partners so as to take account of the variation between the basis of 
the property to the partnership and its fair market value at the time 
of contribution. If a partner contributes property with built-in gain 
or built-in loss to a partnership, and the partnership subsequently 
sells the property and recognizes that gain or loss, the regulations 
under section 704(c)(1)(A) generally require the partnership to 
allocate that gain or loss to the contributing partner.
    The Treasury Department and the IRS agree that it may be unclear 
how the presence of section 704(c) property affects the partnership's 
apportionment of its basis in its properties among its partners for 
purposes of the computation of relevant basis, and that the final 
regulations should provide additional guidance on how section 704(c) 
property affects the computation of relevant basis. Thus, Sec.  1.170A-
14(m)(2)(iii)(B) as finalized in this Treasury Decision provides that 
to determine a partner's portion of the adjusted basis in all of a 
contributing partnership's properties, the contributing partnership 
must apportion among its partners its adjusted basis in each of its 
properties (except the portion of the real property with respect to 
which the qualified conservation contribution is made), using the 
adjusted basis immediately before the qualified conservation 
contribution, without duplication or omission of any property, and by 
treating the adjusted basis in each property as not less than zero. 
Consistent with the proposed regulations, these final regulations 
provide that this apportionment must be done under principles similar 
to the determination of the partners' interests in the partnership 
under section 704(b), but add a cross reference to Sec.  1.704-
1(b)(3)(ii), which provides factors to consider in determining a 
partner's interest in a partnership. These factors include: the 
partners' relative contributions to the partnership, the interests of 
the partners in economic profits and losses (if different than that in 
taxable income or loss), the interests of the partners in cash flow and 
other non-liquidating distributions, and the rights of the partners to 
distributions of capital upon liquidation. In addition, Sec.  1.170A-
14(m)(2)(iii)(B) as finalized provides that the apportionment must 
reflect section 704(c) principles. For example, if a partnership 
property has built-in loss (the adjusted basis of the property exceeds 
its fair market value), and section 704(c) would require that built-in 
loss to be allocated to a certain partner if that property were sold, 
all of the basis in the property that exceeds the property's fair 
market value must be apportioned to the partner to whom the loss would 
be allocated if the property was sold.
    The final regulations contain two examples illustrating the effect 
of section 704(c) property upon the computation of relevant basis. In 
the

[[Page 54292]]

first example (Sec.  1.170A-14(m)(7)(iv) (Example 4)), one partner 
contributes property with built-in gain to the partnership. The 
partnership later makes a qualified conservation contribution with 
respect to other property. The example shows how the partnership's 
basis in the built-in gain property is apportioned among the partners 
for the purposes of determining relevant basis.
    The second example (Sec.  1.170A-14(m)(7)(v) (Example 5)) involves 
the same facts, except that the property contributed to the partnership 
has built-in loss instead of built-in gain. The example shows how the 
basis in the built-in-loss property is apportioned among the partners 
for the purposes of determining relevant basis.
    The change to Sec.  1.170A-14(m)(2)(iii)(B) is also reflected in 
the formulaic version of the rule in Sec.  1.170A-14(m)(2)(iv) in these 
final regulations. Specifically, item D is modified to read:

D = Ultimate member's portion of the adjusted basis in all the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made) as determined under Sec.  1.170A-
14(m)(2)(iii)(B).
2. Determination of Relevant Basis for Ultimate Members That Are 
Shareholders in a Contributing S Corporation
    Proposed Sec.  1.170A-14(m)(3)(i) provided that relevant basis for 
an ultimate member holding a direct interest in a contributing S 
corporation would equal the ultimate member's modified basis multiplied 
by a fraction: (1) the numerator of which is the ultimate member's pro 
rata portion of the contributing S corporation's adjusted basis in the 
portion of the real property with respect to which the qualified 
conservation contribution is made; and (2) the denominator of which is 
the ultimate member's pro rata portion of the adjusted basis in all the 
contributing S corporation's properties (including the portion of the 
real property with respect to which the qualified conservation 
contribution is made). Proposed Sec.  1.170A-14(m)(3)(ii) provided the 
following formulaic version of this rule:

R = M x (E / F)

Where:

R = Relevant basis.
M = Modified basis as determined under Sec.  1.170A-14(l).
E = Ultimate member's pro rata portion of the contributing S 
corporation's adjusted basis in the portion of the real property 
with respect to which the qualified conservation contribution is 
made.
F = Ultimate member's pro rata portion of the adjusted basis in all 
the contributing S corporation's properties (including the portion 
of the real property with respect to which the qualified 
conservation contribution is made).

    Commenters did not raise issues specifically concerning the formula 
for S corporations but did express concerns regarding the complexity of 
proposed Sec.  1.170A-14(m) in general. In the view of the Treasury 
Department and the IRS, this formula accurately accounts for modified 
basis as a portion of the real property by simply taking the pro rata 
allocation of adjusted basis in the contributed property over the pro 
rata allocation of adjusted basis in all the S corporation's properties 
and is not more complex than necessary to carry out the purposes of the 
Disallowance Rule.
    The Treasury Department and the IRS considered several alternatives 
to this rule. One method would be to require a determination of a 
portion of relevant basis for every day during the S corporation's 
taxable year, because S corporations generally allocate the 
contribution on a pro rata basis among the shareholders on each day of 
the taxable year. These final regulations do not take that approach 
because such an approach, although technically accurate and consistent 
with the purposes of the Disallowance Rule, would be too burdensome for 
taxpayers and difficult for the IRS to administer.
    Accordingly, these final regulations finalize proposed Sec.  
1.170A-14(m)(3) without change.
3. Determination of Relevant Basis for Partners in Upper-Tier 
Partnerships
    Proposed Sec.  1.170A-14(m)(4) provided rules for determining the 
relevant basis of an ultimate member holding a direct interest in an 
upper-tier partnership. Proposed Sec.  1.170A-14(m)(4)(i) provided that 
each such ultimate member's modified basis must be traced through all 
upper-tier partnerships to the contributing partnership, and the 
contributing partnership must determine the relevant basis. This would 
involve a multi-step process under which, beginning with the upper-tier 
partnership in which the ultimate member holds a direct interest, each 
upper-tier partnership would be required to perform calculations, and 
then finally the contributing partnership would be required to use 
those calculations to compute the ultimate member's relevant basis.
    Proposed Sec.  1.170A-14(m)(4)(ii)(A) provided that the upper-tier 
partnership must determine the portion of each ultimate member's 
modified basis that is allocable to the upper-tier partnership's 
interest in the partnership in which it holds a direct interest (in a 
situation involving only two tiers of partnerships, that will be the 
contributing partnership). This determination must be done in 
accordance with the principles of proposed Sec.  1.170A-14(m)(2) and 
the formula provided in proposed Sec.  1.170A-14(m)(4)(ii)(B). In other 
words, the formula provided in proposed Sec.  1.170A-14(m)(4)(ii)(B) is 
similar to the formula provided in proposed Sec.  1.170A-14(m)(2)(iv), 
except that, instead of determining the portion of modified basis that 
is allocable to the portion of the real property with respect to which 
the qualified conservation contribution is made, the formula in 
proposed Sec.  1.170A-14(m)(4)(ii)(B) determines the portion of 
modified basis that is allocable to the upper-tier partnership's 
interest in the next lower-tier partnership. As explained in proposed 
Sec.  1.170A-14(m)(4)(iii), the contributing partnership will then use 
the amount determined under the formula in proposed Sec.  1.170A-
14(m)(4)(ii)(B) to compute the portion of modified basis that is 
allocable to the portion of the real property with respect to which the 
qualified conservation contribution is made.
    Proposed Sec.  1.170A-14(m)(4)(ii)(B) provided the following 
formula:

G = M x (U / (J + U))

Where:

G = The portion of the ultimate member's modified basis that is 
allocable to the upper-tier partnership's interest in the 
contributing partnership.
M = Modified basis as determined under Sec.  1.170A-14(l).
J = Ultimate member's portion of the adjusted basis in all the 
upper-tier partnership's properties (other than the upper-tier 
partnership's interest in the contributing partnership), determined 
by apportioning among the partners of the upper-tier partnership in 
accordance with their interests in the partnership under section 
704(b) its adjusted basis in each of its properties (other than the 
upper-tier partnership's interest in the contributing partnership), 
using the adjusted bases immediately before the qualified 
conservation contribution, without duplication or omission of any 
property, and by treating the adjusted basis in each property as not 
less than zero.
U = Ultimate member's share of the upper-tier partnership's adjusted 
basis in its interest in the contributing partnership, determined 
according to the following formula: H x (B / K).
H = Upper-tier partnership's adjusted basis in its interest in the 
contributing partnership.
B = Ultimate member's distributive share of the qualified 
conservation contribution.

[[Page 54293]]

K = Upper-tier partnership's allocated portion of the qualified 
conservation contribution.

    Proposed Sec.  1.170A-14(m)(4)(iii) provided that, after completion 
of these computations, the contributing partnership must determine the 
portion of the amount determined under item G with respect to each 
ultimate member that is allocable to the portion of the real property 
with respect to which the qualified conservation contribution is made. 
This determination must be done in accordance with the principles of 
Sec.  1.170A-14(m)(2), and the following formula:

R = G x (V / (L + V))

Where:

R = Relevant basis.
G = Amount determined with respect to item G as described under 
Sec.  1.170A-14(m)(4)(ii)(B).
L = Upper-tier partnership's portion of adjusted basis in all the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made), determined by apportioning among the partners 
of the contributing partnership in accordance with their interests 
in the partnership under section 704(b) its adjusted basis in each 
of its properties (except the interest in the contributing 
partnership), using the adjusted bases immediately before the 
qualified conservation contribution, without duplication or omission 
of any property, and by treating the adjusted basis in each property 
as not less than zero.
V = Upper-tier partnership's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made, determined 
according to the following formula: A x (K / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
K = Upper-tier partnership's allocated portion of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.
a. Complexity of the Determination of Relevant Basis for Ultimate 
Members That are Partners in an Upper-Tier Partnership
    Several commenters criticized the complexity of the proposed 
regulations' method for determining relevant basis in tiered entity 
arrangements. For example, one commenter stated that the proposed 
regulations use ``difficult multivariable mathematical formulae'' like 
G = M x (U / (J + U)) and R = G x (V / (L + V)). The commenter stated 
that these calculations ``are appropriate for launching rockets or 
building bridges, but not for claiming Congressionally-encouraged tax 
incentives for land conservation.'' Another commenter stated that the 
complexity of the proposed regulations places a significant burden on 
the IRS and the Independent Office of Appeals to determine compliance 
at the level of an ``indeterminable number'' of upper-tier 
partnerships. The commenter stated that the proposed regulations 
provide an ``unclear legal standard with respect to the application of 
the Disallowance Rule to tiered partnership structures and thus do not 
promote simplification and taxpayer burden reduction.''
    Another commenter stated that, of the conservation easement 
contributions made by partnerships, very few are made by tiered 
partnerships. The commenter stated that, after enactment of the 
Disallowance Rule, there will be even fewer, noting that many of those 
structures were created to facilitate transactions that are now banned.
    The Treasury Department and the IRS have determined that the 
proposed computations are not more complex than necessary to effectuate 
the Disallowance Rule. In the context of tiered entities, section 
170(h)(7)(A) requires the Disallowance Rule to be tested at each tier 
and requires relevant basis to be determined by looking through all 
tiers of pass-through entities to determine the portion of modified 
basis that is attributable to the portion of the real property with 
respect to which the qualified conservation contribution is made. For 
example, if an individual is a partner in an upper-tier partnership, 
and a lower-tier partnership makes a qualified conservation 
contribution, section 170(h)(7)(A) requires each partnership to 
determine if the amount of the contribution exceeds 2.5 times the sum 
of the relevant bases. Section 170(h)(7)(B)(i) provides that the 
individual's relevant basis is the portion of the individual's modified 
basis in the upper-tier partnership that is allocable (under rules 
similar to the rules of section 755) to the portion of the real 
property held by the lower-tier partnership with respect to which the 
qualified conservation contribution is made.
    Applying the rules of section 755 to tiered entities involves 
computations at each tier, which can be complex. Revenue Ruling 87-115, 
1987-2 C.B. 163, Situation 1, describes the sale of an interest in an 
upper-tier partnership that holds an interest in a lower-tier 
partnership. The upper-tier partnership and the lower-tier partnership 
both have elections in effect under section 754 of the Code. Rev. Rul. 
87-115 concludes that, in addition to the upper-tier partnership 
computing section 743(b) adjustments and allocating them among its 
properties under section 755, an interest in the lower-tier partnership 
will be deemed to have been transferred for purposes of the lower-tier 
partnership computing section 743(b) adjustments and allocating them 
among the lower-tier partnership's properties under section 755. Thus, 
the rules of section 755 will have to be applied at each tier. 
Similarly, Revenue Ruling 92-15, 1992-1 C.B. 215, Situation 1, provides 
that if an upper-tier partnership makes an adjustment under section 
734(b) that is allocated under the rules of section 755 to the basis of 
an interest it holds in a lower-tier partnership that has an election 
under section 754 in effect, the lower-tier partnership must make 
section 734(b) adjustments to the upper-tier partnership's share of the 
lower-tier partnership's assets and allocate those adjustments among 
the lower-tier partnership's property under the rules of section 755. 
Thus, the rules of section 755 will have to be applied at each tier to 
determine the allocation of the section 734(b) adjustments.
    As explained earlier, the proposed regulations are similar to, and 
not more complex than, the rules of section 755. In addition, the 
proposed regulations are more consistent with the purposes of the 
Disallowance Rule than a rule that simply cross-references section 755. 
Both of these statements are also true with respect to tiered 
partnership arrangements. The computational step-by-step approach in 
the proposed regulations provides a clear, administrable standard, and 
protects the purposes of the Disallowance Rule in situations involving 
tiered partnerships.
    The Treasury Department and the IRS disagree with the commenter who 
stated that the proposed regulations apply to an ``indeterminate'' 
number of tiers. The number of tiers is determinable, and within the 
control of the taxpayers creating those tiers. The proposed regulations 
provide a flexible approach to accommodate any number of tiers created 
by taxpayers. This flexibility is necessary to prevent the avoidance of 
the purposes of the Disallowance Rule. If the regulations stopped at 
two tiers, taxpayers could create structures with additional tiers and 
assert that they are not required to properly trace relevant basis 
through all the tiers. In addition, one commenter reported that many 
tiered partnership arrangements were created to engage in the very 
types of abusive transactions which led Congress to enact the 
Disallowance Rule.

[[Page 54294]]

Accordingly, these final regulations do not make changes in response to 
the comments regarding the complexity of the relevant basis 
computations in tiered partnership situations.
b. Effect of Section 704(c) on the Allocation of Modified Basis
    As discussed in Part II.B.1.b of this Summary of Comments and 
Explanation of Revisions, these final regulations amend Sec.  1.170A-
14(m)(2)(iii)(B) and item D in the formula in Sec.  1.170A-
14(m)(2)(iv), which address the apportionment of a contributing 
partnership's adjusted bases in its properties. To provide a parallel 
rule for an upper-tier partnership's apportionment of its adjusted 
bases in its properties, Sec.  1.170A-14(m)(4)(ii)(A)(2) in these final 
regulations provides that to determine a partner's portion of the 
adjusted basis in all of an upper-tier partnership's properties, the 
upper-tier partnership must apportion among its partners its adjusted 
basis in each of its properties (except its interest in the lower-tier 
partnership), using the adjusted basis immediately before the qualified 
conservation contribution, without duplication or omission of any 
property, and by treating the adjusted basis in each property as not 
less than zero. This apportionment must be done under principles 
similar to the determination of the partners' interests in the 
partnership under section 704(b), including the factors in Sec.  1.704-
1(b)(3)(ii). In addition, the apportionment must reflect section 704(c) 
principles. For example, if a partnership property has built-in loss 
(the adjusted basis of the property exceeds its fair market value), and 
section 704(c) would require all of that built-in loss to be allocated 
to a certain partner if that property was sold, all of the basis in the 
property that exceeds the property's fair market value must be 
apportioned to the partner to whom the loss would be allocated if the 
property was sold.
    To effectuate this change, these final regulations modify the 
definition of item J in Sec.  1.170A-14(m)(4)(ii)(B) to be:

    J = Ultimate member's portion of the adjusted basis in all the 
upper-tier partnership's properties (other than the upper-tier 
partnership's interest in the contributing partnership) as 
determined under Sec.  1.170A-14(m)(4)(ii)(A)(2).
    To be consistent with the changes to Sec.  1.170A-
14(m)(2)(iii)(B), these final regulations modify the definition of 
item L in Sec.  1.170A-14(m)(4)(ii)(B) to be:
    L = Upper-tier partnership's portion of adjusted basis in all 
the contributing partnership's properties (other than the portion of 
the real property with respect to which the qualified conservation 
contribution is made) as determined under Sec.  1.170A-
14(m)(2)(iii)(B).
4. Determination of Relevant Basis for Shareholders in Upper-Tier S 
Corporations
    Proposed Sec.  1.170A-14(m)(5) provided rules for determining 
relevant basis for an ultimate member holding a direct interest in an 
upper-tier S corporation. Proposed Sec.  1.170A-14(m)(5)(i) provided 
that the ultimate member's modified basis must be traced through the 
upper-tier S corporation and any upper-tier partnerships to the 
contributing partnership, and the contributing partnership must 
determine the relevant basis. This involves a multi-step process under 
which, beginning with the upper-tier S corporation, the upper-tier S 
corporation and any upper-tier partnerships would be required to 
perform calculations, and then finally the contributing partnership 
would be required to use those calculations to compute the ultimate 
member's relevant basis.
    Proposed Sec.  1.170A-14(m)(5)(ii)(A) provided a narrative rule for 
the upper-tier S corporation. Under proposed Sec.  1.170A-
14(m)(5)(ii)(A), the upper-tier S corporation must determine the 
portion of each ultimate member's modified basis that is allocable to 
the upper-tier S corporation's interest in the partnership in which it 
holds a direct interest (in a situation involving only two tiers, that 
will be the contributing partnership). This determination must be done 
in accordance with the principles of Sec.  1.170A-14(m)(3) and the 
formula provided in Sec.  1.170A-14(m)(5)(ii)(B). In other words, the 
formula provided in Sec.  1.170A-14(m)(5)(ii)(B) is similar to the 
formula provided in Sec.  1.170A-14(m)(3), except that, instead of 
determining the portion of modified basis that is allocable to the 
portion of the real property with respect to which the qualified 
conservation contribution is made, the formula in Sec.  1.170A-
14(m)(5)(ii)(B) determines the portion of modified basis that is 
allocable to the upper-tier S corporation's interest in the next lower-
tier partnership. As explained in Sec.  1.170A-14(m)(5)(iii), the 
contributing partnership will then use the amount determined under the 
formula in Sec.  1.170A-14(m)(5)(ii)(B) to compute the portion of 
modified basis that is allocable to the portion of the real property 
with respect to which the qualified conservation contribution is made.
    Proposed Sec.  1.170A-14(m)(5)(ii)(B) provided the following 
formula:

N = M x (P / Q)

Where:

N = Portion of the ultimate member's modified basis that is 
allocable to the upper-tier S corporation's interest in the 
contributing partnership.
M = Modified basis as determined under Sec.  1.170A-14(l).
P = Ultimate member's pro rata portion of the upper-tier S 
corporation's adjusted basis in its interest in the contributing 
partnership.
Q = Ultimate member's pro rata portion of the adjusted basis in all 
the upper-tier S corporation's properties (including the upper-tier 
S corporation's adjusted basis in its interest in the contributing 
partnership).

    Proposed Sec.  1.170A-14(m)(5)(iii) provided that, after completion 
of these computations, the contributing partnership must determine the 
portion of the amount determined under item N with respect to each 
ultimate member that is allocable to the portion of the real property 
with respect to which the qualified conservation contribution is made. 
This determination must be done in accordance with the principles of 
Sec.  1.170A-14(m)(2), and the following formula:

R = N x (W / (S + W))

Where:

R = Relevant basis.
N = Amount determined with respect to item N as described under 
Sec.  1.170A-14(m)(5)(ii)(B).
S = Upper-tier S corporation's portion of the adjusted basis in all 
the contributing partnership's properties (other than the portion of 
the real property with respect to which the qualified conservation 
contribution is made), determined by apportioning among the partners 
of the contributing partnership in accordance with their interests 
in the partnership under section 704(b) its adjusted basis in each 
of its properties (other than the portion of the real property with 
respect to which the qualified conservation contribution is made), 
using the adjusted bases immediately before the qualified 
conservation contribution, without duplication or omission of any 
property, and by treating the adjusted basis in each property as not 
less than zero.
W = Upper-tier S corporation's share of the contributing 
partnership's adjusted basis in the portion of the real property 
with respect to which the qualified conservation contribution is 
made, determined according to the following formula: A x (Y / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
Y = Upper-tier S corporation's allocated portion of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

[[Page 54295]]

a. Complexity of the Determination of Relevant Basis for Ultimate 
Members That are Shareholders in an Upper-Tier S Corporation
    Commenters did not provide comments specific to S corporations, but 
an upper-tier S corporation would necessarily hold an interest in a 
partnership, so the rules applicable to partnerships would apply to any 
partnership owned by the S corporation. For the reasons described in 
Part II.B.3.a of this Summary of Comments and Explanation of Revisions 
(relating to the complexity of the determination of relevant basis for 
ultimate members that are partners in an upper-tier partnership), the 
Treasury Department and the IRS have determined that these computations 
should be retained. Accordingly, these final regulations do not make 
changes in response to the comments regarding the complexity of the 
relevant basis computations in situations involving an S corporation 
owning an interest in a lower-tier partnership.
b. Effect of Section 704(c) on the Allocation of Modified Basis
    As discussed in Part II.B.1.b of this Summary of Comments and 
Explanation of Revisions, these final regulations amend Sec.  1.170A-
14(m)(2)(iii)(B) and item D in the formula in Sec.  1.170A-
14(m)(2)(iv). To be consistent with those revisions, these final 
regulations modify the definition of item S in Sec.  1.170A-
14(m)(5)(iii)(B) to be:
    S = Upper-tier S corporation's portion of the adjusted basis in all 
the contributing partnership's properties (other than the portion of 
the real property with respect to which the qualified conservation 
contribution is made) as determined under Sec.  1.170A-
14(m)(2)(iii)(B).

III. Requests for Guidance on Partnership Allocations

    Subchapter K and the regulations thereunder provide rules on how a 
partnership may allocate its items among its partners. Several 
commenters requested that the final regulations provide guidance on 
partnership allocations of qualified conservation contributions. These 
comments are grouped into the following categories: (A) requests for 
guidance under section 704(b), (B) requests for guidance under section 
704(c), and (C) requests for additional guidance on the application of 
the proposed regulations under Sec.  1.706-3.
A. Requests for Guidance Under Section 704(b)
    Section 704(b) provides that a partner's distributive share of 
income, gain, loss, deduction, or credit is determined in accordance 
with the partner's interest in the partnership if the partnership 
agreement does not provide as to the partner's distributive share of 
these items or the allocation to a partner of these items under the 
agreement does not have substantial economic effect. The existing 
regulations under section 704(b) provide guidance, including 
definitions of substantial economic effect, capital account provisions, 
and guidance on the determination of a partner's interest in the 
partnership.
    The proposed regulations did not address section 704(b) allocation 
issues. The examples in the proposed regulations tell the reader to 
assume that the partnership allocations comply with the rules of 
subchapter K. Commenters requested guidance on the following issues 
involving section 704(b): (1) allocations of qualified conservation 
contributions under section 704(b), and (2) section 704(b) capital 
accounting for qualified conservation contributions.
1. Allocations of Qualified Conservation Contributions Under Section 
704(b)
    One commenter stated that the proposed regulations suggest that a 
partnership can allocate qualified conservation contributions in any 
manner it chooses irrespective of the rules under subchapter K. The 
commenter stated that a partnership's allocation of a qualified 
conservation contribution must reflect either the partners' interests 
in the partnership or qualify as a special allocation that satisfies 
the substantial economic effect rules. The commenter recommended that 
the final regulations qualify any suggestion that special allocations 
may be used in allocating qualified conservation contributions. Without 
that, the commenter stated that the examples in the proposed 
regulations may be taken as permission from the IRS to create a new 
situation in which an investor receives more than 2.5 times its basis 
in tax deductions.
    The proposed regulations do not suggest that a partnership's 
allocation of a qualified conservation contribution is not subject to 
the rules of subchapter K. As noted, the examples in the proposed 
regulations tell the reader to assume that the partnership allocations 
comply with the rules of subchapter K. The focus of these regulations 
is the implementation of section 170(f)(19) and (h)(7), which generally 
do not change the rules for how a partnership may allocate a qualified 
conservation contribution among its partners under section 704(b). 
Accordingly, guidance on the application of section 704(b) to a 
partnership's allocations of qualified conservation contributions is 
outside the scope of these regulations.
    The Treasury Department and the IRS note that the Disallowance Rule 
does not prevent all situations in which an investor receives more than 
2.5 times its basis in tax-deductible qualified conservation 
contributions. See Sec.  1.170A-14(j)(6)(ii) (Example 2) for a 
situation in which the amount of a partnership's qualified conservation 
contribution does not exceed 2.5 times the sum of the partners' 
relevant bases, even though one partner's share of the contribution 
exceeds 2.5 times that partner's relevant basis. Such transactions may, 
however, constitute a listed transaction.
2. Section 704(b) Capital Accounting for Qualified Conservation 
Contributions
    Regulations under section 704(b) provide rules for maintenance of a 
partner's capital account. In general terms, a partner's capital 
account is increased by the amount of money the partner contributes to 
the partnership, the fair market value of property the partner 
contributes to the partnership, and allocations to the partner of 
partnership income and gain. In general terms, a partner's capital 
account is decreased by the amount of money distributed to the partner 
by the partnership, the fair market value of any property distributed 
to the partner, allocations of section 705(a)(2)(B) expenditures of the 
partnership, and allocations of partnership loss and deduction. See 
Sec.  1.704-1(b)(2)(iv). Section 705(a)(2)(B) expenditures are 
expenditures of a partnership that are not deductible in computing its 
taxable income and not properly chargeable to its capital accounts. 
Revenue Ruling 96-11, 1996-1 C.B. 140, provides that a noncash 
charitable contribution by a partnership is a section 705(a)(2)(B) 
expenditure.
    Two commenters requested guidance on how a disallowed qualified 
conservation contribution would affect capital accounts. They stated 
that the proposed regulations provide rules for determining whether a 
qualified conservation contribution runs afoul of section 170(h)(7) but 
fail to provide capital accounting guidance under section 704(b) to the 
extent that a contribution is disallowed. One commenter stated that, 
under the current section 704(b) regulations, it is unclear what impact 
a disallowed

[[Page 54296]]

qualified conservation contribution would have on book capital 
accounts. Another commenter stated that, in the event that a 
contributing partnership continues to conduct business following a 
disallowed qualified conservation contribution, the lack of section 
704(b) guidance will create confusion among tax practitioners, increase 
the reporting burden on taxpayers, and require further guidance from 
the Treasury Department and the IRS. These two commenters recommend 
that the final regulations include book capital account guidance under 
section 704(b) with respect to the Disallowance Rule.
    The Treasury Department and the IRS have concluded that guidance on 
capital account maintenance under section 704(b) is outside the scope 
of these regulations. There are several situations in which the Code 
limits or disallows a deduction for a partnership's charitable 
contribution, including other provisions of section 170. As a result of 
these long-standing rules, a partnership's allowed charitable 
contribution may be less than the fair market value of the donated 
property. The Disallowance Rule simply adds another situation in which 
a deduction for a partnership's charitable contribution will be 
disallowed. Thus, this issue is broader than contributions subject to 
the Disallowance Rule. Accordingly, these final regulations do not 
address partnership capital accounting.
B. Requests for Guidance Under Section 704(c)
    In part, section 704(c) provides rules for partnership allocations 
with respect to property that had built-in gain or built-in loss at the 
time the property was contributed by a partner to the partnership. Two 
commenters sought guidance on whether: (1) section 704(c)(1)(A) applies 
to qualified conservation contributions, and (2) section 704(c)(1)(B) 
applies to qualified conservation contributions.
1. Application of Section 704(c)(1)(A) to Charitable Contributions
    Two commenters requested guidance on whether section 704(c)(1)(A) 
applies to the definition of distributive share in the context of 
proposed Sec.  1.170A-14. The commenters stated that the proposed 
regulations do not define the term ``distributive share.'' The 
commenters stated that, as a result, it is unclear whether section 
704(c) may apply to determine each partner's distributive share of a 
qualified conservation contribution. One commenter stated that, to 
promote transparency, the final regulations should define the term 
``distributive share'' and further discuss what impact, if any, section 
704(c) may have with respect to conservation easement transactions in 
the context of section 170(h).
    Another commenter stated that none of the examples in the proposed 
regulations involve a qualified conservation contribution with respect 
to property that had been contributed to the partnership by a partner, 
and that the application of section 704(c) to allocations of charitable 
contributions should be addressed. The commenter hypothesized that the 
proposed regulations will create an inference that the rules of section 
704(c) do not apply in the context of a contributed property that is 
later the subject of a charitable contribution because it is unclear 
under the existing section 704(c) regulations whether charitable 
contributions of contributed property are subject to section 704(c). 
The commenter also attached or referenced several articles addressing 
whether Congress intended for section 704(c) to apply to charitable 
contributions.
    The focus of these regulations is implementation of section 
170(f)(19) and (h)(7). Thus, the application of section 704(c)(1)(A) to 
charitable contributions by a partnership is outside the scope of these 
regulations. However, the Treasury Department and the IRS will continue 
to study the issue.
2. Application of Section 704(c)(1)(B) to Charitable Contributions
    Section 704(c)(1)(B) provides in part that, if a partner 
contributes property with built-in gain or built-in loss to a 
partnership, and the partnership distributes the property (directly or 
indirectly) to someone other than the contributing partner within seven 
years of the partner's contribution, the contributing partner is 
treated as recognizing gain or loss (as the case may be) from the sale 
of such property in an amount equal to the gain or loss which would 
have been allocated to such partner under section 704(c)(1)(A) if the 
property had been sold at its fair market value at the time of the 
distribution.
    One commenter requested guidance on whether section 704(c)(1)(B) 
would apply if a partner contributes real property to a partnership and 
within seven years the partnership makes a qualified conservation 
contribution with respect to that property. The commenter stated that a 
partnership's charitable contribution is substantively equivalent to a 
partnership distribution followed by a charitable contribution by the 
partners.
    The focus of these regulations is implementation of section 
170(f)(19) and (h)(7). Thus, the application of section 704(c)(1)(B) to 
charitable contributions by a partnership is outside the scope of these 
regulations. However, the Treasury Department and the IRS will continue 
to study the issue.
C. Proposed Regulations Under Sec.  1.706-3
    Section 706(d)(3) of the Code provides rules for an upper-tier 
partnership's allocation of items to its partners attributable to an 
interest in a lower-tier partnership. It provides that if, during any 
taxable year of the upper-tier partnership, there is a change in any 
partner's interest in the upper-tier partnership, then (except to the 
extent provided in regulations) each partner's distributive share of 
any item of the upper-tier partnership attributable to the lower-tier 
partnership must be determined by assigning the appropriate portion 
(determined by applying principles similar to the principles of section 
706(d)(2)(C) and (D)) of each such item to the appropriate days during 
which the upper-tier partnership is a partner in the lower-tier 
partnership and by allocating the portion assigned to any such day 
among the partners in proportion to their interests in the upper-tier 
partnership at the close of such day.
    To facilitate the computation of a partner's relevant basis 
immediately before the contribution, proposed Sec.  1.706-3(a) provided 
that, for purposes of section 706(d)(3), in the case of a qualified 
conservation contribution (without regard to whether such contribution 
is a disallowed qualified conservation contribution within the meaning 
of proposed Sec.  1.170A-14(j)(3)(vii)) by a partnership that is 
allocated to an upper-tier partnership, the upper-tier partnership must 
allocate the contribution among its partners in proportion to their 
interests in the upper-tier partnership at the time of day at which the 
contribution was made, regardless of the method (interim closing or 
proration) and convention (daily, semi-monthly, or monthly) otherwise 
used by the upper-tier partnership under Sec.  1.706-4.
    The following sections of this Summary of Comments and Explanation 
of Revisions address two issues under proposed Sec.  1.706-3(a): (1) 
whether proposed Sec.  1.706-3(a) requires pro rata allocations, and 
(2) whether proposed Sec.  1.706-3(a) withdraws the 2015 proposed 
regulations under Sec.  1.706-3.
1. Whether Proposed Sec.  1.706-3(a) Requires Pro Rata Allocations
    The Treasury Department and the IRS understand that there are 
questions

[[Page 54297]]

whether the language in proposed Sec.  1.706-3(a) stating that the 
upper-tier partnership must allocate the qualified conservation 
contribution among its partners ``in proportion to their interests in 
the upper-tier partnership'' requires the upper-tier partnership to 
allocate the contribution among its partners pro rata, with no special 
allocations.
    The Treasury Department and the IRS did not intend for proposed 
Sec.  1.706-3(a) to require an upper-tier partnership to allocate a 
qualified conservation contribution pro rata among its partners. 
Accordingly, the final regulations modify Sec.  1.706-3(a) to provide 
that the upper-tier partnership must allocate the contribution among 
its partners in accordance with their interests in the qualified 
conservation contribution at the time of day at which the qualified 
conservation contribution was made, rather than providing that the 
upper-tier partnership must allocate the contribution among its 
partners ``in proportion to their interests in the upper-tier 
partnership'' at the time of day at which the contribution was made.
2. Whether Proposed Sec.  1.706-3(a) and (b) Withdraw the 2015 Proposed 
Regulations Under Sec.  1.706-3
    One commenter asked about the effect of the proposed regulations on 
proposed regulations under Sec.  1.706-3 published August 3, 2015, REG-
109370-10 (80 FR 45905) (the 2015 proposed regulations). The 2015 
proposed regulations proposed guidance under the general rule of 
section 706(d)(3).
    The proposed regulations did not withdraw, nor did they intend to 
withdraw, the 2015 proposed regulations. Instead, the proposed 
regulations under Sec.  1.706-3 are a regulatory exception to the 
general rule in section 706(d)(3), to which the 2015 proposed 
regulations relate. To avoid confusion, these regulations renumber the 
guidance under Sec.  1.706-3 to follow the numbering in the 2015 
proposed regulations. Thus, proposed Sec.  1.706-3(a) and (b) are 
finalized as Sec.  1.706-3(d) and (e), incorporating the changes 
described in this section of the preamble. Section 1.706-3(a) through 
(c) are reserved for the 2015 proposed regulations.
    In addition, the Treasury Department and the IRS have determined 
that the language in proposed Sec.  1.706-3 might cause confusion 
because it states that the upper-tier partnership must allocate the 
qualified conservation contribution as described in Sec.  1.706-3 
regardless of the method (interim closing or proration) and convention 
(daily, semi-monthly, or monthly) otherwise used by the upper-tier 
partnership under Sec.  1.706-4. This reference to Sec.  1.706-4 might 
cause confusion because Sec.  1.706-4(a)(2) provides in part that items 
subject to allocation under section 706(d)(3) are not subject to the 
rules of Sec.  1.706-4. Thus, although proposed Sec.  1.706-3 is 
correct to state that the upper-tier partnership's allocation of the 
qualified conservation contribution must be done without regard to the 
rules of Sec.  1.706-4, the reference to Sec.  1.706-4 may be read to 
imply that the rules of Sec.  1.706-4 would otherwise apply to an 
upper-tier partnership's allocation of items attributable to a lower-
tier partnership.
    To avoid confusion, these final regulations modify proposed Sec.  
1.706-3(a) to provide that, for purposes of section 706(d)(3), in the 
case of a qualified conservation contribution (as defined in section 
170(h)(1) and Sec.  1.170A-14(a) without regard to whether such 
contribution is a disallowed qualified conservation contribution within 
the meaning of Sec.  1.170A-14(j)(3)(vii)) by a partnership that is 
allocated to an upper-tier partnership, the upper-tier partnership must 
allocate the contribution among its partners in accordance with their 
interests in the qualified conservation contribution at the time of day 
at which the qualified conservation contribution was made, regardless 
of the general rule of section 706(d)(3). The final regulations provide 
that, pursuant to Sec.  1.706-4(a)(2), the rules of Sec.  1.706-4 do 
not apply to allocations subject to Sec.  1.706-3.

IV. Exceptions to the Disallowance Rule

    Section 170(h)(7) contains three exceptions to the Disallowance 
Rule: the three-year holding period exception, the family pass-through 
entity exception, and the certified historic structure exception. The 
proposed regulations included each exception and provided additional 
guidance. Commenters addressed each of these exceptions, requested an 
exception for de minimis overages, and requested a more explicit 
statement of the taxpayers to whom the Disallowance Rule does not 
apply. Each category of comments is discussed in turn in the following 
sections of this preamble.
A. Exception for Contributions Outside Three-Year Holding Period
    Section 170(h)(7)(C) provides that the Disallowance Rule does not 
apply to any contribution made at least three years after the latest 
of: (1) the last date on which the pass-through entity that made such 
contribution acquired any portion of the real property with respect to 
which such contribution is made, (2) the last date on which any owner 
of the pass-through entity that made such contribution acquired any 
interest in such pass-through entity, and (3) if the interest in the 
pass-through entity that made such contribution is held through one or 
more pass-through entities, the last date on which any such pass-
through entity acquired any interest in any other such pass-through 
entity, and the last date on which any owner in any such pass-through 
entity acquired any interest in such pass-through entity.\4\ Neither 
section 605 of the SECURE 2.0 Act nor section 170 defines the phrase 
``acquired any interest.''
---------------------------------------------------------------------------

    \4\ The Treasury Department and the IRS note that section 
170(h)(7)(C) and Sec.  1.170A-14(n)(2) are based upon dates of 
acquisition, not ``holding periods,'' and therefore, although this 
exception is colloquially referred to as the ``three-year holding 
period exception,'' the tacked holding period rules of section 1223 
of the Code do not apply in determining the application of section 
170(h)(7)(C) and Sec.  1.170A-14(n)(2).
---------------------------------------------------------------------------

    Proposed Sec.  1.170A-14(n)(2)(ii) and (iii) defined the phrase 
``acquired any interest'' for partnerships and S corporations, 
respectively. Proposed Sec.  1.170A-14(n)(2)(iv) also clarified that, 
if the contributing partnership or contributing S corporation does not 
satisfy the requirements of proposed Sec.  1.170A-14(n)(2), then 
proposed Sec.  1.170A-14(n)(2) would not apply to any person who 
receives a distributive share or pro rata share of the qualified 
conservation contribution (including an upper-tier partnership or 
upper-tier S corporation), regardless of whether the person receiving 
such distributive share or pro rata share would have satisfied the 
requirements of proposed Sec.  1.170A-14(n)(2) if the person had been 
the one to make the qualified conservation contribution. The proposed 
regulations contained two examples illustrating these rules. The 
preamble to the proposed regulations requested comments on whether any 
additional rules or examples should be provided for the three-year 
holding period exception.
    The only comment received on proposed Sec.  1.170A-14(n)(2) 
supported the three-year holding period exception and stated that no 
further guidance is needed on the topic. Accordingly, these regulations 
finalize the proposed regulations under Sec.  1.170A-14(n)(2) without 
change.
B. Exception for Family Pass-Through Entities
    Section 170(h)(7)(D)(i) provides that the Disallowance Rule does 
not apply to any contribution made by any pass-through entity if 
substantially all of the interests in such pass-through entity are

[[Page 54298]]

held, directly or indirectly, by an individual and members of the 
family of such individual. Section 170(h)(7)(D)(ii) provides that, for 
purposes of section 170(h)(7)(D), the term ``members of the family'' 
means, with respect to any individual: (1) the spouse of such 
individual, and (2) any individual who bears a relationship to such 
individual that is described in section 152(d)(2)(A) through (G) of the 
Code for purposes of determining whether an individual is a qualifying 
relative.
    Proposed Sec.  1.170A-14(n)(3) provided guidance under the family 
pass-through entity exception for partnerships and S corporations, 
including: (1) defining ``substantially all of the interests,'' (2) 
providing that ``members of the family'' are limited to individuals, 
and (3) imposing two anti-abuse rules for the family pass-through 
entity exception.
    In addition, proposed Sec.  1.170A-14(n)(3)(v) provided that, if 
the contributing partnership or contributing S corporation does not 
satisfy the requirements of proposed Sec.  1.170A-14(n)(3), then the 
exception in proposed Sec.  1.170A-14(n)(3) would not apply to any 
person who receives a distributive share or pro rata share of the 
qualified conservation contribution (including an upper-tier 
partnership or upper-tier S corporation), regardless of whether the 
person receiving such distributive share or pro rata share would have 
satisfied the requirements of proposed Sec.  1.170A-14(n)(3) if the 
person had been the one to make the contribution. No comments were 
received on the rule in proposed Sec.  1.170A-14(n)(3)(v). Accordingly, 
the rule in proposed Sec.  1.170A-14(n)(3)(v) is finalized without 
change.
    One commenter expressed support for the family pass-through entity 
exception and stated that further guidance was not needed. Other 
commenters requested modifications on: (1) the definition of 
``substantially all of the interests,'' (2) the limitation of ``members 
of the family'' to individuals, and (3) the two anti-abuse rules for 
the family pass-through entity exception.
1. Defining ``Substantially All of the Interests''
    Section 170(h)(7) does not contain a definition of ``substantially 
all.'' The preamble to the proposed regulations mentioned that, for 
purposes of applying different provisions of the Code that also use 
that term, various Income Tax Regulations define the term 
``substantially all'' as comprising different percentages, including: 
70 percent (Sec.  1.1400Z2(d)-2(d)(4)); 80 percent (Sec. Sec.  1.41-
2(d)(2), 1.41-4(a)(6)); 85 percent (Sec. Sec.  1.45D-1(c)(5), 1.72(e)-
1T, Q&A 3, 1.528-4(b) and (c)); 90 percent (Sec. Sec.  1.103-
8(a)(1)(i), 1.103-16(c), 1.731-2(c)(3)(i), 1.1400Z2(d)-2(d)(3)); and 95 
percent (Sec. Sec.  1.448-1T(e)(4)(i) and (e)(5)(i), 1.460-
6(d)(4)(i)(D)(1)).
    The preamble to the proposed regulations stated that it is 
appropriate to select a percentage at the higher end of this range to 
carry out the purpose of the Disallowance Rule, which is to prevent 
abusive syndications of qualified conservation contributions. Thus, 
proposed Sec.  1.170A-14(n)(3)(i) provided that the family pass-through 
entity exception applied if at least ninety percent of the interests in 
the contributing partnership or contributing S corporation are held by 
an individual and members of the family of such individual and the 
contributing partnership or contributing S corporation meets the 
requirements of proposed Sec.  1.170A-14(n)(3).
    Proposed Sec.  1.170A-14(n)(3)(ii)(A) provided that, in the case of 
a contributing partnership, at least ninety percent of the interests in 
the contributing partnership are held by an individual and members of 
the family of such individual if, at the time of the qualified 
conservation contribution, at least ninety percent of the interests in 
capital and profits in such partnership are held, directly or 
indirectly, by an individual and members of the family of such 
individual. Proposed Sec.  1.170A-14(n)(3)(ii)(B) provided that, in the 
case of a contributing S corporation, at least ninety percent of the 
interests in the contributing S corporation are held by an individual 
and members of the family of such individual if, at the time of the 
qualified conservation contribution, at least ninety percent of the 
total value and at least ninety percent of the total voting power of 
the outstanding stock in such S corporation are held by an individual 
and members of the family of such individual.
    One commenter agreed that ninety percent was a reasonable number to 
define substantially all, noting that interests held by persons who are 
not members of the family should be ``extremely limited.'' Another 
commenter stated that ninety percent was too high and would 
unnecessarily restrict the application of the family pass-through 
entity exception; however, that commenter did not provide any examples 
of unnecessary restrictions or recommend a different percentage. A 
third commenter recommended lowering the percentage to eighty-five 
percent, citing the eighty-five percent standard in Rev. Rul. 73-248, 
1973-1 C.B. 295, and the fact that this Revenue Ruling relates to the 
percentage of ownership in a legal entity, as opposed to the percentage 
of cash, percentage of assets, or percentage of time. This commenter 
also noted that eighty-five percent was closest to the average of the 
various percentages used to define ``substantially all'' discussed in 
the preamble to the proposed regulations.
    The Treasury Department and the IRS agree with the commenter 
stating that interests held by persons who are not members of the 
family should be extremely limited and that that ninety percent is a 
reasonable number to define ``substantially all.'' In the view of the 
Treasury Department and the IRS, the intent of not requiring one-
hundred percent of a contributing entity to be owned by family members 
was to allow non-family members to make small, non-material investments 
in contributing entities, such as when a family partnership issues 
profits interests to service providers. The two commenters who stated 
that ninety percent is too high did not elaborate or give examples in 
which a family partnership or family S corporation needed to provide 
more than ten percent of its interests to persons who are not members 
of the family but still should meet the family pass-through entity 
exception to the Disallowance Rule. Further, the average of percentages 
used to define ``substantially all'' in guidance is not relevant to the 
definition that makes sense in the context of section 170(h)(7). Thus, 
these final regulations adopt the definition of ``substantially all'' 
as proposed.
2. Defining ``Members of the Family''
    Consistent with section 170(h)(7)(D)(ii), proposed Sec.  1.170A-
14(n)(3)(iii) provided that, for purposes of Sec.  1.170A-14(n)(3), the 
term ``members of the family'' means, with respect to any individual: 
(1) the spouse of such individual, and (2) any individual who bears a 
relationship to such individual that is described in section 
152(d)(2)(A) through (G). The preamble to the proposed regulations 
stated that, under this rule, members of the family would be limited to 
individuals and requested comments on whether certain estates or trusts 
should be treated as members of the family for purposes of the family 
pass-through entity exception. The preamble also noted that, under 
existing Sec.  1.1361-1(e)(3)(ii), certain estates and trusts of 
deceased members of the family are treated as members of the family for 
purposes of the limitation on the number of shareholders in an S 
corporation.
    One commenter requested that estates and trusts of deceased 
individuals be included in the definition of ``members of the family'' 
to address the fact that

[[Page 54299]]

the interests of deceased individuals may be included in conservation 
contributions.
    In the view of the Treasury Department and the IRS, if a family 
member dies and the member's interest in the pass-through entity has 
been transferred to the decedent's estate, the interest still should be 
considered to be held by a member of the family. Otherwise, the pass-
through entity might have to wait until final disposition of the estate 
(which may take years) to make a deductible qualified conservation 
contribution, even if the beneficiaries of the estate are all 
themselves individual members of the family. In addition, allowing a 
decedent's estate to be treated as a member of the family if the 
decedent was a member of the family at the time of death is 
administrable because determining whether the estate qualified as a 
member of the family involves the same determination as whether the 
decedent qualified as a member of the family before death. Accordingly, 
these final regulations modify Sec.  1.170A-14(n)(3)(iii) to provide 
that a decedent's estate is treated as a member of the family for 
purposes of Sec.  1.170A-14(n)(3) if the decedent was a member of the 
family at the time of death.
    In addition, as noted by the commenter, certain trusts may raise 
similar issues. Trusts may be partners or S corporation shareholders, 
or may become partners or shareholders as a result of the death of an 
individual member of the family. For example, if a family member holds 
a partnership interest through a grantor trust, that individual would 
meet the requirements under these regulations of holding a direct 
interest in the partnership under Sec.  1.170A-14(j)(3)(v). If that 
family member dies and the trust is no longer a grantor trust, the 
trust should not automatically cause the partnership to no longer be a 
family partnership. If only family members are potential beneficiaries 
of a trust, then the trust should be treated as being a member of the 
family. Including such a trust would serve the purpose of the statute 
to maintain an exception for partnerships and S corporations owned and 
controlled by a family. A contributing partnership or contributing S 
corporation that would otherwise satisfy the requirements of the family 
pass-through entity exception should not be excluded from the exception 
merely because interests are held through a family trust. Accordingly, 
these final regulations modify Sec.  1.170A-14(n)(3)(iii) to provide 
that a trust, all of the beneficiaries of which are individuals 
described in Sec.  1.170A-14(n)(3)(iii)(A) or (B), is treated as a 
member of the family. For this purpose, the term ``beneficiaries'' 
refers to those persons who currently must or may receive income or 
principal from the trust and those persons who would succeed to the 
property of the trust if the trust were to terminate immediately before 
the qualified conservation contribution.
3. Anti-Abuse Rules for the Family Pass-Through Entity Exception
    The Disallowance Rule and its exceptions in section 170(h)(7) are 
generally mechanical. However, Congress recognized that additional 
guidance may be needed to prevent situations in which those mechanical 
rules are used to avoid the purposes of the Disallowance Rule. Section 
170(h)(7)(G)(ii) provides the Secretary with authority to issue 
regulations or other guidance to prevent the avoidance of the purposes 
of section 170(h)(7). Accordingly, to ensure that the family pass-
through entity exception in proposed Sec.  1.170A-14(n)(3) would not be 
used inappropriately to circumvent the Disallowance Rule, the proposed 
regulations contained two anti-abuse rules: (1) a one-year holding 
period, and (2) a ninety-percent allocation rule.
a. One-Year Holding Period
    Proposed Sec.  1.170A-14(n)(3)(iv)(A) provided that the family 
pass-through entity exception does not apply unless at least ninety 
percent of the interests in the property with respect to which the 
qualified conservation contribution was made were owned, directly or 
indirectly, by one individual and members of the family of that 
individual for at least one year prior to the date of the contribution.
    The preamble to the proposed regulations explained that the need 
for such a rule is the concern that, in the absence of a requirement 
that the members of the family hold the contributed property for a 
certain period before the contribution, promoters could structure 
transactions to inappropriately take advantage of certain tacked-
holding-period transactions together with the family pass-through 
entity exception. The proposed regulations provided an example of such 
a situation, in which a lower-tier partnership that is not a family 
pass-through entity distributes its real property to an S corporation 
and an upper-tier partnership. The S corporation and the upper-tier 
partnership each separately qualify as a family pass-through entity, 
but the shareholders of the S corporation are not related to the 
partners of the upper-tier partnership. Within one year of the 
distribution, the S corporation makes a qualified conservation 
contribution. The example concludes that, even though at the time of 
the qualified conservation contribution the S corporation is completely 
owned by an individual and members of the family, the family pass-
through entity exception does not apply because the one-year holding 
period requirement was not met.
    Two commenters disagreed with the one-year holding period. These 
commenters claimed that the inclusion of a three-year holding period 
under section 170(h)(7)(C) and the absence of a one-year holding period 
under the family pass-through entity exception evidenced a 
congressional intent not to include a one-year holding period for the 
family pass-through entity exception under section 170(h)(7)(D). One of 
these commenters opined that the proposed one-year holding period 
requirement violated due process by retroactively binding taxpayers who 
had already made contributions that did not satisfy the one-year 
holding period. The other commenter stated that the Treasury Department 
and the IRS had offered no evidence in support of the statement in the 
preamble to the proposed regulations that reliance on a tacked holding 
period raises serious concerns that the family pass-through entity 
exception is being used inappropriately to circumvent the Disallowance 
Rule.
    The Treasury Department and the IRS disagree that the Treasury 
Department and the IRS lack authority to promulgate an anti-abuse rule. 
Section 170(h)(7)(G) is a specific grant of authority to the Secretary 
to prescribe such regulations or other guidance as may be necessary or 
appropriate to carry out the purposes of section 170(h)(7), including 
regulations or other guidance to prevent the avoidance of the purposes 
of section 170(h)(7). In addition, section 7805(a) authorizes the 
Secretary to prescribe all needful rules and regulations for the 
enforcement of title 26, including all rules and regulations as may be 
necessary by reason of any alteration of law in relation to internal 
revenue. As noted above, section 7805(b)(2) permits regulations issued 
within 18 months of December 29, 2022 (the date SECURE 2.0 Act was 
enacted), to apply to contributions after December 29, 2022. Section 
7805(b)(3) provides that the Secretary may provide that any regulation 
may take effect or apply retroactively to prevent abuse. Section 
170(h)(7)(G) and section 7805(a), (b)(2), and (b)(3) provide ample 
authority for an anti-abuse rule applicable to contributions after 
December 29, 2022.

    The holding period anti-abuse rule is necessary to address the 
potential for taxpayers to inappropriately take advantage of certain 
tacked-holding-period transactions to utilize the family pass-through 
entity exception. In particular, the example in the proposed 
regulations illustrates inappropriate avoidance of the purposes of the 
Disallowance Rule. As described, the example shows a distribution from 
a partnership that is not a family pass-through entity to two separate 
upper-tier entities, each of which is a family pass-through entity, 
followed by a qualified conservation contribution within one year of 
the distribution. This situation should not qualify for the family 
pass-through entity exception because the distributing partnership was 
not a family pass-through entity. If such a situation qualified for the 
family pass-through entity exception, then partnerships that fail to 
qualify as family pass-through entities could simply distribute land to 
upper-tier entities, each of which would be a family pass-through 
entity (such as single-member S corporations or partnerships wholly-
owned by spouses) and thus each upper-tier entity could inappropriately 
avail itself of the family pass-through entity exception. Without an 
anti-abuse rule, similar inappropriate results could be obtained 
through other tacked-holding-period transactions, including 
contributions to family pass-through entities by persons who are not 
members of the family.
    However, after consideration of the comments, the Treasury 
Department and the IRS have decided to finalize the one-year holding 
period rule with two changes. First, the final regulations clarify 
that, solely for purposes of Sec.  1.170A-14(n)(3)(iv)(A), section 
1223(1) and (2) of the Code do not apply in determining whether at 
least ninety percent of the interests in the property with respect to 
which the qualified conservation contribution was made were owned, 
directly or indirectly, by one individual and members of the family of 
that individual for at least one year prior to the date of the 
contribution. This clarification is only for purposes of the anti-abuse 
rule in Sec.  1.170A-14(n)(3)(iv)(A) and does not affect the holding 
period of the property for any other purpose, including section 170(e). 
The Treasury Department and the IRS note that this rule was already 
implicit in the proposed regulations; in fact, proposed Sec.  1.170A-
14(n)(3)(vi)(B) (Example 2) described a situation in which an S 
corporation failed the one-year holding period requirement even though 
it would have had a tacked holding period under section 1223 that 
exceeded one year.
    Second, the final regulations provide that the one-year holding 
period rule does not apply if the entire amount of the qualified 
conservation contribution is limited by section 170(e) to the 
contributing partnership's or contributing S corporation's adjusted 
basis in the qualified conservation contribution. For example, if 
section 170(e) limits a qualified conservation contribution to the 
contributing partnership's adjusted basis because the property with 
respect to which the qualified conservation contribution is made was 
purchased within one year of the qualified conservation contribution, 
the anti-abuse rule in Sec.  1.170A-14(n)(3)(iv)(A) does not apply. 
This change limits the one-year holding requirement to transactions 
that inappropriately take advantage of tacked holding periods to 
utilize the family pass-through entity exception.
b. Ninety Percent Allocation Rule
    Proposed Sec.  1.170A-14(n)(3)(iv)(B) provided that the exception 
in proposed Sec.  1.170A-14(n)(3) does not apply unless at least ninety 
percent of the qualified conservation contribution is allocated to the 
individual and all members of the individual's family who own at least 
ninety percent of all the interests in the contributing partnership or 
contributing S corporation. Commenters did not comment on this anti-
abuse rule. Therefore, these regulations maintain the ninety percent 
allocation rule.
C. Certified Historic Structure Exception
    Section 170(h)(7)(E) provides that the Disallowance Rule does not 
apply to any qualified conservation contribution the conservation 
purpose of which is the preservation of any building that is a 
certified historic structure (as defined in section 170(h)(4)(C)). 
Proposed Sec.  1.170A-14(n)(4) simply repeated this statutory language 
and did not provide further guidance regarding the cases to which this 
exception would apply. No comments were received on proposed Sec.  
1.170A-14(n)(4), which these regulations finalize without change.
    Proposed Sec.  1.170A-14(n)(4) also contained a cross-reference to 
the special reporting requirements in proposed Sec.  1.170A-16(f)(6) 
for a contribution that meets the certified historic structure 
exception. Several commenters addressed these special reporting 
requirements. Those comments are discussed in Part V.D of this Summary 
of Comments and Explanation of Revisions,
D. The Request for a De Minimis Overage Exception
    Section 170(h)(7)(A) states that a contribution by a partnership 
(whether directly or as a distributive share of a contribution of 
another partnership) ``shall not be treated as'' a qualified 
conservation contribution for purposes of section 170 if the amount of 
such contribution exceeds 2.5 times the sum of each partner's relevant 
basis in such partnership. One commenter stated that there is a ``cliff 
effect'' to the statute and the proposed regulations in that a 
contribution of one dollar more than 2.5 times the sum of the relevant 
bases results in disallowance of any deduction for any of the 
contribution. The commenter stated that there should be some regulatory 
leniency if the taxpayer was acting in good faith and there is de 
minimis overage.
    The Treasury Department and the IRS agree with the commenter that 
the statutory language imposes a ``cliff effect,'' but do not agree 
that a de minimis exception is necessary or desirable. As explained in 
Part I of this Summary of Comments and Explanation of Revisions, the 
first sentence of proposed Sec.  1.170A-14(j)(3)(ii), which these 
regulations finalize without change, provides that the amount of a 
contributing partnership's or contributing S corporation's qualified 
conservation contribution is the amount claimed as a qualified 
conservation contribution on the return of the contributing partnership 
or contributing S corporation for the taxable year in which the 
contribution is made. By focusing on the amount claimed by the 
contributing partnership or contributing S corporation, rather than the 
fair market value of the contribution, this rule provides greater 
certainty to both taxpayers and the IRS. The regulations do not require 
the contributing partnership or contributing S corporation to claim the 
full amount of the contribution that it might otherwise claim in the 
absence of the Disallowance Rule. Therefore, a contributing partnership 
or contributing S corporation making a contribution that would 
otherwise be disallowed by the Disallowance Rule could avoid the 
Disallowance Rule by claiming an amount of qualified conservation 
contribution that is less than or equal to 2.5 times the sum of the 
relevant bases, assuming that the claimed amount is not more than the 
fair market value of the contribution. Thus, taxpayers may be able to 
mitigate the ``cliff effect'' noted by the commenter.
    In accordance with section 170(h)(7)(G), which provides authority

[[Page 54301]]

for the Secretary to prescribe such regulations or other guidance as 
may be necessary or appropriate to carry out the purposes of section 
170(h)(7), including to prevent the avoidance of the purposes of 
section 170(h)(7), these final regulations also provide that, if a 
partner or S corporation shareholder claims an amount of qualified 
conservation contribution that is inconsistent with and greater than 
the amount of the partner's distributive share or S corporation 
shareholder's pro rata share of qualified conservation contribution 
reported to the partner or S corporation shareholder by the partnership 
or S corporation, predicated on a position that the partnership's or S 
corporation's qualified conservation contribution was a greater amount 
than the amount claimed by the partnership or S corporation, and the 
qualified conservation contribution would have been a disallowed 
qualified conservation contribution if the partnership or S corporation 
had actually claimed that greater amount, then the partner's or S 
corporation shareholder's claimed qualified conservation contribution 
is a disallowed qualified conservation contribution. This rule is 
necessary to avoid situations in which a partner or an S corporation 
shareholder seeks to avoid the application of section 170(h)(7) by 
claiming an amount with respect to a qualified conservation 
contribution that is more than the amount allocated to the partner or 
shareholder and reported by the partnership or S corporation.
E. Statement Regarding Taxpayers to Whom the Disallowance Rule Does Not 
Apply
    One commenter stated that the proposed regulations lacked clarity 
as to which provisions apply to every contributing partnership or 
contributing S corporation and requested that the final regulations 
include a preliminary explanation of scope. The commenter recommended 
that, if different provisions have different scopes, then that should 
be made clear. The commenter recommended that the final regulations 
explicitly state that Sec.  1.170A-14(j) through (n) does not apply to 
qualified conservation contributions made by individuals, joint 
tenancies, tenancies in common, or C corporations. The commenter also 
recommended that the final regulations explicitly state that Sec.  
1.170A-14(j) through (n) does not apply to partnerships and entities 
taxed as partnerships: (1) which have held the real property subject to 
the qualified conservation contribution for more than one year 
immediately before the date and hour of the qualified conservation 
contribution, disregarding any tacked holding period; and (2) all of 
whose members, on the date and time of the qualified conservation 
contribution, have held the same percentage interest in the 
partnership, directly or indirectly, disregarding any tacked holding 
period, for more than one year immediately before the date and hour of 
the qualified conservation contribution.
    With respect to the request to clarify that Sec.  1.170A-14(j) 
through (n) does not apply to qualified conservation contributions made 
by individuals, joint tenancies, tenancies in common, or by C 
corporations, the Treasury Department and the IRS agree in part. 
Section 170(h)(7)(A) and (F) provide that the Disallowance Rule applies 
only to certain qualified conservation contributions made by 
partnerships, S corporations, and other pass-through entities; thus, it 
does not apply to qualified conservation contributions made by 
individuals or C corporations. However, in certain cases an arrangement 
that is a joint tenancy or tenancy in common under State law may be 
considered a partnership for Federal tax purposes. See Sec.  301.7701-
1(a)(2). If so, a qualified conservation contribution by such an 
arrangement would be subject to the Disallowance Rule. Accordingly, 
Sec.  1.170A-14(j)(1) of these final regulations includes a statement 
that the Disallowance Rule does not apply to qualified conservation 
contributions made directly by landowners that are not pass-through 
entities, such as individuals or C corporations.
    With respect to the request to clarify that Sec.  1.170A-14(j) 
through (n) does not apply to partnerships and entities taxed as 
partnerships: (1) which have held the real property subject to the 
qualified conservation contribution for more than one year immediately 
before the date and hour of the qualified conservation contribution, 
disregarding any tacked-on holding period and (2) all of whose members, 
on the date and time of the qualified conservation contribution, have 
held the same percentage interest in the partnership, directly or 
indirectly, disregarding any tacked holding period, for more than one 
year immediately before the date and hour of the qualified conservation 
contribution, the Treasury Department and the IRS have concluded that 
such a rule would be inconsistent with section 170(h)(7). As explained 
in Part IV.A of this Summary of Comments and Explanation of Revisions, 
section 170(h)(7)(C) provides an exception to the Disallowance Rule for 
pass-through entities that satisfy a three-year holding period. 
Accordingly, the final regulations do not adopt this recommendation.

V. Reporting Requirements

    Section 170(f)(11)(H) grants the Treasury Department and the IRS 
authority to promulgate regulations to provide for substantiation of a 
charitable contribution. Section 170(h)(7)(G) grants the Treasury 
Department and the IRS authority to promulgate regulations to carry out 
the purposes of section 170(h)(7), including to require reporting 
(including reporting related to tiered partnerships and the modified 
basis of partners and S corporation shareholders).
    As noted in the preamble to the proposed regulations, existing 
Sec.  1.170A-16 imposes substantiation and reporting requirements for 
noncash charitable contributions, including but not limited to 
qualified conservation contributions by pass-through entities. Subject 
to certain exceptions, Sec.  1.170A-16 requires the donor to file Form 
8283 in the case of a noncash charitable contribution exceeding $500. 
Specifically, existing Sec.  1.170A-16(c) generally requires the donor 
to complete Form 8283 (Section A) in the case of a noncash charitable 
contribution of more than $500 but not more than $5,000. Existing Sec.  
1.170A-16(d) generally requires the donor to complete Form 8283 
(Section A or Section B, as applicable) in the case of a noncash 
charitable contribution of more than $5,000. Existing Sec.  1.170A-
16(e) applies to noncash charitable contributions of more than $500,000 
and generally requires the donor to complete Form 8283 (Section A or 
Section B, as applicable). Section 170(f)(11)(D) and existing Sec.  
1.170A-16(e) require a donor of a noncash contribution of more than 
$500,000 to attach a qualified appraisal to the return on which the 
deduction is claimed. Existing Sec.  1.170A-16(f) provides additional 
substantiation rules, including rules for donors that are partnerships 
or S corporations.
    The proposed regulations provided guidance in the following four 
categories: (1) requirements for all noncash charitable contributions 
of more than $500, (2) requirements for noncash charitable 
contributions by partnerships and S corporations, (3) requirements for 
qualified conservation contributions made by partnerships and S 
corporations, and (4) requirements for qualified conservation 
contributions made by partnerships and S corporations the conservation 
purpose of which is the preservation of a certified historic structure.

[[Page 54302]]

A. Requirements for All Noncash Charitable Contributions of More Than 
$500
    The proposed regulations made one clarifying change applicable to 
all noncash charitable contributions of more than $500--a requirement 
that taxpayers input numerical entries into Form 8283.
    Section 1.170A-16(c)(3) provides the elements of a completed Form 
8283 (Section A), and Sec.  1.170A-16(d)(3) provides the elements of a 
completed Form 8283 (Section B). To further clarify reporting 
requirements for donated property, proposed Sec.  1.170A-16(c)(3)(v) 
and (d)(3)(ix) each added a requirement, respectively, that, if a 
number can be inserted into any box on Form 8283, the number must be 
inserted in the box on Form 8283; alternatively, taxpayers may attach a 
statement to the Form 8283 explaining why a number cannot be inserted. 
The proposed regulations also clarified that, while nothing precludes a 
taxpayer from both inserting the number in the appropriate box on Form 
8283 and including an attached statement explaining any additional 
information regarding the number, taxpayers may not respond to a 
request for information on Form 8283 with nonresponsive responses, for 
example, by indicating that the requested information is available upon 
request or will be provided upon request. The proposed regulations 
provided that inclusion of such nonresponsive language in response to a 
request for information on Form 8283 may be treated by the IRS as being 
an incomplete filing of Form 8283.
    The preamble to the proposed regulations explained the IRS had 
observed a pronounced increase in taxpayers filing a Form 8283 that did 
not contain any numbers and instead referred the IRS to an attachment. 
Often, the attachment included nonresponsive information, such as 
``available upon request,'' was entirely blank, or otherwise did not 
provide the information required by Form 8283. Other times, the 
attachment included multiple numbers for different boxes, leaving the 
IRS to figure out which of the included numbers was appropriate for a 
particular box. The proposed regulations stated that these actions are 
to the detriment of fair and effective tax administration, and stated,

    While many taxpayers understandably want to attach a statement 
to the Form 8283 to verify their calculations and provide 
appropriate supplemental information, having the numerical 
information in the appropriate box on Sections A and B of Form 8283 
is critical to the IRS's ability to ensure the integrity of each 
filing, as IRS systems are programmed to match a partner's or 
shareholder's information to the appropriate contributing 
partnership's or contributing S corporation's information. Moreover, 
information requested on Sections A and B of Form 8283 is 
information that the partnership or S corporation should already 
have and is already required to provide to the partner or 
shareholder, as appropriate.

    A commenter suggested that confusion could be avoided if the 
regulation stated that an attached statement will only be acceptable if 
it clearly explains why the taxpayer cannot provide the basis of their 
donation or is simply explanatory of the basis the taxpayer provided. 
The commenter also suggested that the box requiring the taxpayer to 
report its basis in the donated property could be left blank if the 
taxpayer provided an explanatory statement attached to the Form 8283. 
The same commenter suggested that the regulations add a box for the 
taxpayer to check if the entire explanation and number are contained in 
an attached statement. These comments are largely already addressed by 
the proposed regulations, which provided that taxpayers may attach a 
statement to the Form 8283 explaining why a number cannot be inserted 
and also clarified that nothing precludes a taxpayer from both 
inserting the number in the appropriate box on Form 8283 and including 
an attached statement explaining any additional information regarding 
the number. The request to add a box to check if the entire explanation 
and number are contained in the attached statement is outside the scope 
of these final regulations but will be considered in connection with 
updates to the Form 8283.
    One commenter agreed with the Treasury Department and the IRS's 
``general attitude toward Form 8283 and taxpayers who leave information 
blank,'' but requested that the Form 8283 include a box to disclose 
tacked holding periods. This commenter noted that the Form 8283 
currently only contains a box for ``date acquired by donor'' and stated 
that accountants had expressed confusion over whether acquisition date 
or holding period date ought to be inserted into that box, because the 
holding period date is the relevant date for all other accounting and 
tax purposes. The commenter suggested that adding a box for the holding 
period would account for potential disparities between the date entered 
in the ``date acquired by donor'' box and the actual date when a 
donor's holding period began to run.
    The request to add a box for the holding period is outside the 
scope of these final regulations but will be considered in connection 
with updates to the Form 8283. The Treasury Department and IRS 
emphasize that current instructions to Form 8283 direct taxpayers to 
enter the date the property is acquired by the donor and that taxpayers 
may submit an attachment disclosing the tacked holding period to 
explain potential disparities between the date acquired by the donor 
and the date the donor's holding period began to run.
    This commenter also suggested that any increase in the number of 
taxpayers filing Forms 8283 that do not contain numbers and instead 
refer the IRS to an attachment is evidence of taxpayer confusion on how 
to fill out the Form 8283, ``particularly when the IRS has taken a 
litigating position that attempts to disqualify deductions in numerous 
easement cases based on alleged failures in the taxpayers' Forms 
8283.'' The commenter suggested that the final regulations should not 
discourage taxpayers from providing additional information on an 
attachment, particularly if the taxpayer is doing so to supplement 
information on the Form 8283. This comment is consistent with the 
proposed regulations, which provided that taxpayers may attach a 
statement to the Form 8283 explaining why a number cannot be inserted 
and also clarified that nothing precludes a taxpayer from both 
inserting the number in the appropriate box on Form 8283 and including 
an attached statement explaining any additional information regarding 
the number.
    This commenter also proposed that the regulations include a 
``substantial compliance'' standard for Form 8283 for taxpayers who 
make a good faith effort to complete the form. The commenter stated 
that substantial compliance relief should not apply if a taxpayer omits 
information from Form 8283 altogether or otherwise manipulates the 
form, but that if a taxpayer makes a good-faith mistake, such as 
miscalculating basis in a way that does not affect the calculation of 
whether a qualified conservation contribution exceeds 2.5 times the sum 
of the relevant bases, the taxpayer should not be punished by having 
its deduction denied altogether.
    While the IRS may work with a taxpayer to fix a good-faith mistake, 
the Treasury Department and the IRS decline to adopt a ``substantial 
compliance'' standard for Form 8283. First, there are certain reporting 
requirements that are statutorily imposed and cannot be satisfied 
through substantial compliance, including the requirement to obtain a 
qualified appraisal and attach an appraisal summary to the return. See 
Hewitt v.

[[Page 54303]]

Commissioner, 109 T.C. 258, aff'd without published opinion, 166 F.3d 
332 (4th Cir. 1998); Deficit Reduction Act of 1984 (DEFRA), Public Law 
98-369, section 155(a)(3), 98 Stat. 494 (1984). Second, even for those 
reporting requirements that may implicate the substantial compliance 
doctrine, the determination of whether substantial compliance should 
apply is made under common law and should be applied only in cases in 
which the taxpayer acted in good faith and exercised due diligence but 
nevertheless failed to meet regulatory requirements. See Prussner v. 
U.S., 896 F.2d 218, 224 (7th Cir. 1990). See also McAlpine v. 
Commissioner, 968 F.2d 459, 462 (5th Cir. 1992). Substantial compliance 
is not applicable if the requirement is essential but may be applied if 
the requirements are procedural or directory. See Estate of Strickland 
v. Commissioner, 92 T.C. 16, 27 (1989). The determination of whether 
substantial compliance is satisfied is a facts-and-circumstances 
analysis that is ordinarily resolved through the examination, Appeals, 
or judicial process.
    One commenter noted that the requirement to report cost basis has 
been in existence since 1988 and stated that some practitioners have 
failed to scrupulously report either the cost basis, fair market value, 
or both, maintaining that an earlier iteration of the Form 8283 
instructions were vague as to this requirement. The commenter asked 
that the final regulations ``remove all doubt and reaffirm that the 
reporting requirement was never vague or ambiguous.''
    The Treasury Department and the IRS agree that the requirements for 
an accurate Form 8283 have always required the reporting of cost or 
other basis in the donated property. Section 155(a)(1) of DEFRA 
specifically instructs the Secretary to promulgate regulations that 
require a taxpayer claiming a deduction for a noncash charitable 
contribution to: (1) obtain a qualified appraisal for the property, (2) 
attach an appraisal summary to the return on which such deduction is 
first claimed for such contribution, and (3) include on such return 
such additional information (including the cost basis and acquisition 
date of the contributed property) as the Secretary may prescribe in 
such regulations. (Emphasis added). In fulfillment of this mandate, the 
Secretary promulgated Sec.  1.170A-13, Recordkeeping and Return 
Requirements for Deductions for Charitable Contributions. TD 8002, 49 
FR 50663, December 31, 1984. Section 1.170A-13(b)(3)(i)(B) requires 
reporting cost or other basis for charitable contribution deductions in 
excess of $500 if required by the return form or its instructions. 
Section 1.170A-13(b)(3)(ii) provides that, if a taxpayer has reasonable 
cause for being unable to provide such information, the taxpayer must 
attach an explanatory statement to the return. Existing Sec.  1.170A-
16(c)(3)(iv)(F) and (d)(3)(vi) require the reporting of cost or other 
basis on Form 8283. Additionally, section 170(f)(11)(B) and (C) provide 
the Secretary the authority to require information other than property 
descriptions for contributions of more than $500 and requires qualified 
appraisals for contributions of more than $5,000. These final 
regulations clarify requirements for completing certain fields on Form 
8283, but the requirement to include cost basis is clear under existing 
regulations and does not require reiterating in other parts of the 
regulations, including in these final regulations.
    Accordingly, proposed Sec.  1.170A-16(c)(3)(v) and (d)(3)(ix) are 
finalized with only minor, non-substantive changes (such as using the 
term ``non-responsive language'' instead of the term ``non-responsive 
responses'').
B. Requirements for Noncash Charitable Contributions Over $500 by 
Partnerships and S Corporations
    Existing Sec.  1.170A-16(f)(4)(i) provides that, if a partnership 
or S corporation makes a noncash charitable contribution, the 
partnership or S corporation is required to provide a copy of its 
completed Form 8283 (Section A or Section B) to every partner or 
shareholder who receives an allocation of a charitable contribution 
deduction under section 170. Similarly, a recipient partner or 
shareholder that is a partnership or S corporation must provide a copy 
of the completed Form 8283 to each of its partners or shareholders who 
receives an allocation of a charitable contribution deduction under 
section 170 for the property described in Form 8283. Proposed Sec.  
1.170A-16(f)(4)(i) retained these rules and clarified that any 
additional tiers of pass-through entities must also provide a copy of 
the donor's Form 8283 to its partners or shareholders who receive an 
allocation of the charitable contribution.
    Existing Sec.  1.170A-16(f)(4)(ii) requires a partner or S 
corporation shareholder that receives an allocation of a charitable 
contribution to which Sec.  1.170A-16(c), (d), or (e) applies to attach 
a copy of the partnership's or S corporation's completed Form 8283 
(Section A or Section B) to the return on which the deduction is 
claimed. Proposed Sec.  1.170A-16(f)(4)(ii) retained these rules and 
clarified that the partner or shareholder must also attach a copy of 
any additional Forms 8283 that must be provided to them under proposed 
Sec.  1.170A-16(f)(4)(iii)(A).
    Proposed Sec.  1.170A-16(f)(4)(iii)(A) provided that a partner of a 
partnership or shareholder of an S corporation that receives an 
allocation of a charitable contribution to which Sec.  1.170A-16(c), 
(d), or (e) applies must complete its own Form 8283 with any 
information required by Form 8283 and the instructions to Form 8283. In 
addition, proposed Sec.  1.170A-16(f)(4)(iii)(A) provided that a 
partner that is itself a partnership or S corporation must complete its 
own Form 8283 and provide a copy of that Form 8283 to every partner or 
shareholder who receives an allocation of the charitable contribution, 
and so on through any additional tiers. Proposed Sec.  1.170A-
16(f)(4)(iii)(A) required each partner or shareholder to attach its 
separate Form 8283 to the return on which the contribution is claimed, 
in addition to the copy of the donor's Form 8283 as well as other Forms 
8283 that the partner or shareholder received. This proposed 
requirement applied to all noncash charitable contributions over $500 
made by a partnership or S corporation, not just those for conservation 
easements.
    The comments received on these provisions addressed: (1) the 
requirement that partners and S corporation shareholders complete and 
file separate Forms 8283, and (2) donee responsibilities pertaining to 
the partners' and shareholders' Forms 8283.
1. The Form 8283 Filing Requirement for Partners and Shareholders
    One commenter addressed proposed Sec.  1.170A-16(f)(4)(iii)(A). 
This commenter suggested that, rather than requiring partners and S 
corporation shareholders to complete and file separate Forms 8283, the 
donating partnership or S corporation should be required to include on 
its Form 8283 information about the partners' and shareholders' bases 
and holding periods. The commenter suggested retaining the ``current 
approach'' of having one Form 8283 for the contributing partnership 
(that is distributed to the partners) and then requiring the specific 
information the IRS is seeking on the attachment (which is required for 
all qualified conservation contributions) submitted by the partners.
    Section 170(f)(11) disallows a charitable contribution deduction 
unless certain substantiation requirements are met. Providing a Form

[[Page 54304]]

8283 is a reasonable, basic step for substantiating charitable 
contributions for taxpayers who ultimately claim the deduction. 
Congress provided, as part of DEFRA, the authority to require taxpayers 
to submit Forms 8283. The legislative history shows that Congress was 
concerned that ``opportunities to offset income through inflated 
valuations of donated property have been increasingly exploited by tax 
shelter promoters.'' Staff of Senate Comm. on Finance, 98th Cong., 2d 
Sess., Explanation of Provisions of the Deficit Reduction Act of 1984, 
at 503 (Comm. Print 1984). This has long been an area of abuse for 
which taxpayers have creatively sought to avoid transparent reporting 
and instead have attempted to disguise overvalued charitable 
contributions.
    Proposed Sec.  1.170A-16(f)(4)(iii)(A) provides the IRS with 
important information and the burden imposed on taxpayers is reasonable 
in light of the potential for abuse. As the preamble to the proposed 
regulations stated, in pass-through and tiered-entity structures, the 
IRS regularly observes partners and shareholders providing incomplete 
information to substantiate their charitable contribution deductions. A 
partner's or S corporation shareholder's Form 8283 that contains the 
necessary information from the Form K-1 received from the donating 
partnership, donating S corporation, or an upper-tier partnership or 
upper-tier S corporation streamlines processing and efficiency. Thus, 
these final regulations finalize Sec.  1.170A-16(f)(4)(iii)(A) as 
proposed.
2. Donee Responsibilities Pertaining to Partners' and Shareholders' 
Forms 8283
    A commenter stated that the requirement that partners and S 
corporation shareholders provide their own Form 8283 represents 
substantial additional work for donees that likely would make them less 
willing (and able) to assess the accuracy and completeness of Form 
8283. This commenter stated that, if there is an expectation that the 
donee would sign an individual's Form 8283, then it would require more 
due diligence for the donee, creating on-the-ground problems and 
complexities. The commenter also stated that retaining so many copies 
of Forms 8283 as part of their permanent record would significantly 
increase their record-keeping burden (although this commenter also 
stated that the great majority of conservation easement donations are 
not made by partnerships and, of those, very few are made by tiered 
partnerships).
    The proposed regulations did not impose a requirement for the donee 
to sign and/or retain a copy of each partner's and shareholder's Forms 
8283. The requirement in Sec.  1.170A-16(d)(3)(ii) that a completed 
Form 8283 (Section B) include the donee's signature only applies to the 
Form 8283 filed by the donor, in these instances the contributing pass-
through entity. To clarify this issue, the Instructions to Form 8283 
have been updated to provide: ``A member's Form 8283 is not required to 
have signatures.'' See the Form 8283 Instructions released on January 
17, 2024, which state ``(Rev. December 2023)'' after ``Instructions for 
Form 8283'' at the top of the first page.
C. Requirements for Qualified Conservation Contributions Made by 
Partnerships and S Corporations
    As explained in the preamble to the proposed regulations, to ensure 
that taxpayers claiming qualified conservation contributions properly 
comply with section 170(f)(19) and (h)(7), the IRS must have relevant 
basis reporting from both the contributing partnership or contributing 
S corporation and each partner or shareholder receiving an allocation 
of the contribution (which will be ultimate members, upper-tier 
partnerships, or upper-tier S corporations). Accordingly, the proposed 
regulations inserted a new paragraph, proposed Sec.  1.170A-
16(d)(3)(viii),\5\ which provided that, for qualified conservation 
contributions made by a partnership or S corporation, the contributing 
partnership or contributing S corporation must report the sum of each 
ultimate member's relevant basis, computed in accordance with Sec.  
1.170A-14(j) through (m), on the Form 8283 (Section B). Under proposed 
Sec.  1.170A-16(d)(3)(viii), this new requirement did not apply to 
contributions described in section 170(h)(7)(C) and Sec.  1.170A-
14(n)(2) (for contributions made outside of the three-year holding 
period) or section 170(h)(7)(D) and Sec.  1.170A-14(n)(3) (for 
contributions made by certain family partnerships or S corporations), 
provided that they are not also described in section 170(h)(7)(E) and 
Sec.  1.170A-14(n)(4) (for contributions to preserve certified historic 
structures), in which case the reporting requirement did apply.
---------------------------------------------------------------------------

    \5\ The proposed regulations would redesignate existing Sec.  
1.170A-16(d)(3)(viii) as Sec.  1.170A-16(d)(3)(x).
---------------------------------------------------------------------------

    Proposed Sec.  1.170A-16(f)(4)(iii)(B) provided an additional 
substantiation rule for partners and S corporation shareholders 
receiving an allocation of a qualified conservation contribution. That 
paragraph required that an ultimate member's separate Form 8283 must 
include the ultimate member's own relevant basis and that an upper-tier 
partnership's or upper-tier S corporation's separate Form 8283 must 
include the sum of each of its ultimate member's relevant bases. 
Proposed Sec.  1.170A-16(f)(4)(iii)(B) did not apply to contributions 
described in section 170(h)(7)(C) and Sec.  1.170A-14(n)(2) (for 
contributions made outside of the three-year holding period) or section 
170(h)(7)(D) and Sec.  1.170A-14(n)(3) (for contributions made by 
certain family partnerships or S corporations), provided that they are 
not also described in section 170(h)(7)(E) and Sec.  1.170A-14(n)(4) 
(for contributions to preserve certified historic structures), in which 
case proposed paragraph Sec.  1.170A-16(f)(4)(iii)(B) did apply.
    The comments received on these provisions addressed: (1) the 
requirement that ultimate shareholders report relevant basis, (2) 
whether the contributing entity should report the basis in the property 
underlying the qualified conservation contribution or the basis in the 
qualified conservation contribution itself, and (3) requiring reporting 
of relevant basis with respect to a qualified conservation contribution 
that satisfies one of the exceptions to the Disallowance Rule.
1. The Requirement That Ultimate Members Report Relevant Basis
    One commenter interpreted the requirement in the proposed 
regulations that ultimate members report their relevant basis on their 
separate Forms 8283 to mean that the proposed regulations ``require 
individual members and shareholders to determine their relevant basis 
and holding period.'' The commenter stated that a particular problem 
with this new requirement is the complexity of the calculations needed 
for an ultimate member to determine their relevant basis.
    The Treasury Department and the IRS disagree that the proposed 
regulations require each ultimate member to determine its relevant 
basis. As explained in the proposed regulations, relevant basis must be 
determined by the partnership or S corporation. The ultimate member may 
need to share information, such as its basis in its interest in the 
partnership or S corporation, with the partnership or S corporation to 
facilitate this computation. The partnership or S corporation must also 
determine its holding period in the property with respect to which the 
qualified conservation contribution is made.
    Another commenter stated that the requirement that partners and

[[Page 54305]]

shareholders file a separate Form 8283 with respect to certified 
historic structure contributions was a trap for the unwary that was 
confusing, duplicative, and contrary to the statute. In support of this 
premise, the commenter stated that: (1) the requirement that each 
partner and shareholder file a separate Form 8283 reporting its own 
relevant basis does nothing to further the purposes of section 
170(f)(19) and (h)(7); (2) section 170(f)(19) and (h)(7) apply at the 
entity level based on the sum of all the relevant bases, and the 
partners' and shareholders' separate Forms 8283 do not convey the sum 
of all the relevant bases; (3) the Treasury Department and the IRS 
could require the contributing partnership to add an attachment to the 
Form 8283 explaining the partnership's allocations of the qualified 
conservation contribution, such as any contractual limitations 
affecting the partnership's allocations; (4) requiring partners and 
shareholders to report their relevant bases may cause confusion by 
leading the partners and shareholders to believe that application of 
the Disallowance Rule depends on whether the amount of a partner's or 
shareholder's deduction exceeds 2.5 times the partner's or 
shareholder's personal relevant basis; (5) because section 170(f)(19) 
and (h)(7) applies only to pass-through entities and ``almost all'' 
pass-through entities are subject to audit at the entity level pursuant 
to the Bipartisan Budget Act of 2015 (BBA), the IRS does not need 
separate Forms 8283 at any intermediary partner levels; and (6) the 
separate Forms 8283 from partners and shareholders would not achieve 
the intended result of reporting requirements enacted in DEFRA--
triggering an audit of overvalued property. The Treasury Department and 
IRS have considered these comments but conclude that they are not 
persuasive. First, in a structure involving tiered partnerships or S 
corporations, the Disallowance Rule must be tested at each tier. See 
Sec.  1.170A-14(j)(2)(ii). Therefore, each upper-tier partnership and 
upper-tier S corporation must compute 2.5 times the sum of its ultimate 
members' relevant bases. It may be the case that the amount of the 
contributing partnership's contribution does not exceed 2.5 times the 
sum of its ultimate members' relevant bases, but an upper-tier 
partnership's allocated portion does exceed 2.5 times the sum of the 
upper-tier partnership's ultimate members' relevant bases and would be 
subject to the Disallowance Rule. Therefore, it is essential that each 
upper-tier partnership and upper-tier S corporation provide a separate 
Form 8283 so that the IRS can apply the Disallowance Rule to upper-tier 
partnerships and upper-tier S corporations. Second, section 
170(h)(7)(G)(i) provides an explicit grant of authority for the 
promulgation of regulations and other guidance requiring reporting 
related to tiered partnerships and S corporations. Requiring upper-tier 
partnerships and upper-tier S corporations to report the sum of their 
ultimate members' relevant bases is necessary to administer the 
Disallowance Rule and is consistent with the authority granted in 
section 170(h)(7)(G).
    Similarly, the requirement that an ultimate member must report 
their own relevant basis on their separate Form 8283 ensures that the 
relevant basis reported at the ultimate member level is consistent with 
the sum of relevant bases reported by the partnership or S corporation. 
The commenter's suggestion that the partnership's or S corporation's 
Form 8283 could separately list each ultimate member's relevant basis 
would not be as administrable. It is impractical for Form 8283 itself 
to contain sufficient space for each ultimate member's relevant basis 
to be separately listed. Accordingly, the partnership or S corporation 
would need to provide such information on an attachment or additional 
statement. The way in which such an attachment is formatted, how easily 
the information can be found, and whether or not the information is 
actually provided may vary. The Treasury Department and the IRS have 
determined that requiring ultimate members to report their personal 
relevant bases in the appropriate box on the Form 8283 (rather than on 
an attachment to the form) ensures that the information can be easily 
found by the IRS and is in a uniform format for processing by the IRS. 
Thus, even if a contributing partnership or upper-tier partnership is 
subject to entity-level audit under the BBA, the partners' separate 
Forms 8283 provide valuable information in ascertaining the 
partnership's compliance with section 170(f)(19) and (h)(7).
    In addition, the Treasury Department and the IRS note that no S 
corporations and not all partnerships are subject to the BBA audit 
procedures. Accordingly, the Treasury Department and the IRS decline to 
remove the requirement that partners and S corporation shareholders 
report their relevant bases on their separate Forms 8283.
2. Whether the Contributing Entity Should Report the Basis in the 
Property Underlying the Qualified Conservation Contribution or the 
Basis in the Qualified Conservation Contribution Itself
    As noted earlier, the regulations and Form 8283 have long required 
a donor to report its basis in the contributed property. At the time of 
the publication of the proposed regulations in November 2023, the then-
current version of the Form 8283 instructions allowed a donor of a 
qualified conservation contribution to either report its basis in the 
underlying property or its basis in the qualified conservation 
contribution itself. For example, assume a partnership owned 600 acres 
of real property. The partnership donates a conservation easement on 
400 of those acres. Assume the partnership's adjusted basis in those 
400 acres was $2,000,000, and that the partnership's adjusted basis in 
the conservation easement itself was $500,000. Under the then-current 
version of the Form 8283 instructions, the partnership could list 
either $2,000,000 or $500,000 as its basis on the Form 8283; the 
partnership would also be required to indicate whether it was reporting 
its basis in the property underlying the qualified conservation 
contribution or its basis in the qualified conservation contribution 
itself.
    A commenter noted this option in the (then-current) Form 8283 
instructions. The commenter stated that the proposed regulations 
require a contributing partnership or contributing S corporation to 
provide its basis in the property underlying the qualified conservation 
contribution rather than its basis in the qualified conservation 
contribution itself. This commenter believed it would simplify the 
process for the donor, donee, and the IRS if Form 8283 required all 
taxpayers making a qualified conservation contribution to report their 
basis in the property underlying the qualified conservation 
contribution, rather than giving taxpayers a choice.
    The Treasury Department and the IRS note that the proposed 
regulations do not amend the requirement in Sec.  1.170A-16(d)(3)(vi) 
that taxpayers report their basis in contributed property on their 
Forms 8283. Section 170(h)(7)(B)(i) provides that, for purposes of the 
Disallowance Rule, relevant basis is determined with reference to ``the 
portion of the real property with respect to which'' the qualified 
conservation contribution is made. Accordingly, the computations in the 
proposed regulations are generally based on the

[[Page 54306]]

contributing partnership's or contributing S corporation's basis in the 
property underlying the qualified conservation contribution, rather 
than its basis in the qualified conservation contribution itself.
    Although the proposed regulations do not modify the requirement 
that a donor must report its basis in contributed property, the 
Treasury Department and the IRS note that the current version of the 
Form 8283 instructions, released January 17, 2024, which states ``(Rev. 
December 2023)'' after ``Instructions for Form 8283'' at the top of the 
first page, requires a donor of a qualified conservation contribution 
to both report its basis in the underlying real property on Form 8283 
and include information about the cost or adjusted basis of the 
qualified conservation contribution itself in a statement attached to 
Form 8283.
3. Requiring Reporting of Relevant Basis With Respect to a Qualified 
Conservation Contribution That Satisfies One of the Exceptions to the 
Disallowance Rule
    One commenter requested clarification on whether the rule requiring 
Forms 8283 with relevant basis applied to every qualified conservation 
contribution made by a partnership or S corporation, regardless of 
whether the contribution satisfies one of the exceptions to the 
Disallowance Rule. As noted above, proposed Sec.  1.170A-16(d)(3)(viii) 
and (f)(4)(iii)(B) required contributing partnerships, contributing S 
corporations, upper-tier partnerships, upper-tier S corporations, and 
ultimate members to report relevant basis (or the sum of the relevant 
bases) on Form 8283 with respect to a qualified conservation 
contribution. However, these reporting requirements did not apply to 
contributions made outside of the three-year holding period or to 
contributions made by certain family partnerships or S corporations, 
unless the contribution is to preserve a certified historic structure 
(in which case the reporting requirements did apply).
    Because the regulations are already clear on this point, the 
commenter's suggestion is not adopted. Accordingly, these final 
regulations adopt Sec.  1.170A-16(d)(3)(viii) and (f)(4)(iii)(B) with 
only minor non-substantive changes.
D. Requirements for Certified Historic Structure Contributions Made by 
Partnerships and S Corporations
    Although contributions by partnerships or S corporations to 
preserve certified historic structures that exceed 2.5 times the sum of 
the relevant bases are excepted from the Disallowance Rule, they are 
subject to section 170(f)(19). Section 170(f)(19) provides that no 
deduction is allowed under section 170(a) for such a contribution 
unless the pass-through entity making such contribution includes on its 
return for the taxable year in which the contribution is made a 
statement that the pass-through entity made such a contribution and 
provides such information about the contribution as the Secretary may 
require. Section 170(f)(19)(B) provides that section 170(f)(19) applies 
to qualified conservation contributions by pass-through entities 
(whether directly or as a distributive share of a contribution of 
another pass-through entity) the conservation purpose of which is the 
preservation of any building which is a certified historic structure, 
and the amount of which exceeds 2.5 times the sum of each partner's 
relevant basis (as defined in section 170(h)(7)).
    Proposed Sec.  1.170A-16(f)(6)(i) provided that, for any qualified 
conservation contribution described in proposed Sec.  1.170A-
16(f)(6)(ii), no deduction is allowed under section 170 or any other 
provision of the Code under which deductions are allowable to pass-
through entities with respect to such contribution unless each 
partnership or S corporation: (1) includes on its return for the 
taxable year in which the contribution is made a statement that it made 
such a contribution or received such allocated portion and (2) provides 
such information about the contribution as the Secretary may require in 
guidance, forms, or instructions.
    Proposed Sec.  1.170A-16(f)(6)(ii) provided that proposed Sec.  
1.170A-16(f)(6) applies to any qualified conservation contribution, the 
conservation purpose of which is preservation of a building that is a 
certified historic structure, that is either made by a contributing 
partnership or contributing S corporation or that is an allocated 
portion of an upper-tier partnership or upper-tier S corporation, and 
the amount of such contribution or such allocated portion exceeds 2.5 
times the sum of each ultimate member's relevant basis.
    Proposed Sec.  1.170A-16(f)(6)(iii) provided that a partnership or 
S corporation satisfies the requirements of section 170(f)(19)(A) and 
Sec.  1.170A-16(f)(6)(i) by filing a completed Form 8283, including 
information about relevant basis, in accordance with section 170, the 
regulations under section 170, and the instructions to Form 8283.
    As noted above, proposed Sec.  1.170A-16(d)(3)(viii) and 
(f)(4)(iii)(B) required contributing partnerships, contributing S 
corporations, upper-tier partnerships, upper-tier S corporations, and 
ultimate members to report relevant basis (or the sum of the relevant 
bases) on Form 8283 with respect to any qualified conservation 
contribution for the preservation of a certified historic structure, 
regardless of whether the contribution also satisfied the three-year 
holding period exception or the certain family pass-through entity 
exception.
    Two commenters addressed these rules, discussing whether: (1) 
relevant basis accounts for fundamental differences between certified 
historic structure contributions and other types of qualified 
conservation contributions, (2) relevant basis accurately reflects 
abusive certified historic structure contributions, and (3) these 
reporting requirements should apply to certified historic structure 
contributions that also satisfy either the three-year holding period 
exception or the family-pass through entity exception.
1. Differences Between Certified Historic Structure Contributions and 
Other Types of Qualified Conservation Contributions
    Two commenters expressed concern that qualified conservation 
contributions that satisfy the certified historic structure exception 
are fundamentally different than other types of qualified conservation 
contributions (such as a conservation easement to protect greenspace) 
and, as such, the data used for computation of relevant basis should be 
different. One of these commenters stated that protection of certified 
historic structures under section 170(h)(4)(A)(iv) differs 
fundamentally from other conservation purposes in section 
170(h)(4)(A)(i) through (iii) because ``[u]nlike natural lands, which 
typically do not need upkeep, historic properties require a continuous 
influx of capital for rehabilitation and ongoing maintenance 
expenditures to preserve the historic character of the building 
protected by the easement.'' This commenter added that ``open space'' 
qualified conservation contributions allow nature to thrive undisturbed 
while certified historic structure contributions need additional human 
intervention to further the conservation purpose and to preserve the 
historic structure in perpetuity. The commenter stated that money 
flowing into the property-owning partnership that is ``put toward the 
preservation, rehabilitation, or upkeep of the certified historic 
structure'' should be allocated to the

[[Page 54307]]

ultimate member's modified basis, but that the proposed regulations 
``ignore these funds entirely.''
    The commenter offered an example of a taxpayer that acquires a 
building and then invests $2,000,000 into the building after 
acquisition. The commenter stated that the proposed regulations ignore 
both debt financing and capital contributions made after the date of 
contribution, which the commenter stated ``produces odd and unworkable 
results for investors in historic structures,'' and recommended that 
the regulations be amended to ``include these other sources of 
financing in historic properties.'' The commenter also stated that, 
``at the time an easement is donated, cash from investors may be 
earmarked for preservation and rehabilitation of a dilapidated 
structure.'' The commenter remarked that cash raised and debt secured 
is essential for furthering the historic preservation purpose. Thus, 
the commenter asserted that, with respect to certified historic 
structure contributions, the definition of relevant or modified basis 
should include debt and cash necessary for maintaining the conservation 
purpose.
    The Treasury Department and the IRS have concluded that certified 
historic structure contributions should have the same relevant basis 
computation as any other qualified conservation contribution. Although 
the Treasury Department and the IRS recognize that there are 
differences between the conservation purposes for different types of 
qualified conservation contributions, section 170(h)(7) does not 
contemplate different calculations of relevant basis depending on the 
particular conservation purpose. Moreover, section 170(f)(19)(B)(iii) 
specifically refers to relevant basis ``as defined in [section 
170(h)(7)].''
    It is appropriate that the rules for the determination of modified 
basis and relevant basis maintain their focus on the amounts invested 
in the property generating the deduction as of the time of the 
qualified conservation contribution. Including debt and cash earmarked 
for the ongoing maintenance of the conservation purpose would 
contradict the statutory definition of relevant basis and modified 
basis. Section 170(h)(7)(B)(i) provides that relevant basis means the 
portion of a partner's modified basis in the partnership which is 
allocable to the portion of the real property with respect to which a 
qualified charitable contribution is made. This narrow definition of 
relevant basis does not include amounts allocable to other assets. 
Also, section 170(h)(7)(B)(ii)(I) provides that modified basis is 
calculated immediately before the qualified conservation contribution. 
Including future events and costs incurred or paid after the donation 
would defeat the purpose of including a timeline in the definition of 
modified basis.
    Therefore, the final regulations do not provide for different 
calculations for relevant basis depending on different conservation 
purposes. In addition, the computations for relevant basis would not 
treat ``earmarked'' amounts as part of the property with respect to 
which the qualified conservation contribution is made. Thus, for 
example, such amounts would not be included in items A \6\ or E \7\ in 
the relevant basis computations.
---------------------------------------------------------------------------

    \6\ Item A is a contributing partnership's adjusted basis in the 
portion of the real property with respect to which a qualified 
conservation contribution is made.
    \7\ Item E is an ultimate member's pro rata portion of a 
contributing S corporation's adjusted basis in the portion of the 
real property with respect to which a qualified conservation 
contribution is made.
---------------------------------------------------------------------------

2. The Use of Relevant Basis in Identifying Abusive Certified Historic 
Structure Contributions
    One of the commenters stated that relevant basis is not an accurate 
measure to determine whether a certified historic structure 
contribution is abusive, giving the example of three buildings. The 
first building is dilapidated, was purchased for $100,000, and requires 
$900,000 of improvements to reach a $1,000,000 investment value. The 
second building is fully operational with a $1,000,000 acquisition 
cost. It is possible for the owner to enlarge either building under the 
applicable zoning laws. The third building is acquired for $5,000,000, 
but it is fully developed and cannot be enlarged under the applicable 
zoning laws. The owner of each building makes a certified historic 
structure contribution and claims a $1,000,000 contribution.
    The commenter stated that the $100,000 dilapidated building would 
be most in danger of demolition, yet the ratio of the amount of the 
contribution to the building's basis would be 10:1, suggesting an 
abusive transaction. The commenter stated that, with respect to the 
second building, the ratio of the amount of the contribution to the 
building's basis would be 1:1, and the ratio for the third building 
would be 0.2:1. The commenter concluded that, because the third 
building cannot be enlarged under applicable zoning laws, the claimed 
contribution of $1,000,000 would be the most abusive of the three 
donations, yet would appear, under the reporting requirements, as the 
least abusive (because it would have the lowest ratio). The commenter 
concluded that this example illustrates that computing whether a 
certified historic structure contribution exceeds 2.5 times the sum of 
the relevant bases does not appropriately provide relevant information 
for the IRS to determine whether the claimed amount of the contribution 
is abusive. The commenter stated that requiring reporting of the sum of 
the relevant bases could actually lead the IRS away from identifying 
abusive transactions.
    The Treasury Department and the IRS conclude that this comment is 
not persuasive and decline to make the changes that it advocates. The 
purpose of these regulations is to implement section 170(f)(19) and 
(h)(7). Section 170(f)(19) explicitly requires reporting for certified 
historic structure contributions by partnerships and S corporations 
that exceed 2.5 times the sum of the relevant bases (as defined in 
section 170(h)(7)). The fact that the commenter believes that a 
different reporting regime would have been more helpful to the IRS does 
not change the statutory framework with which taxpayers must comply. 
Moreover, the fact pattern described by the commenter raises concerns 
about overvaluation and compliance with section 170. In addition, the 
buildings most in need of preservation are those with the greatest 
significance to American history, not those in the poorest condition 
with an ability to be enlarged. See 36 CFR 60.4 (criteria for National 
Register listing) and 36 CFR 67.4 (criteria for certification of 
historic significance).
    This commenter also stated that relevant basis for certified 
historic structure contributions is particularly difficult to compute. 
The commenter noted the ``sheer number and subjectivity of variables 
that can affect the basis of a commercial building'' and cited as 
examples the segregation of furniture and fixtures from real property 
and the determination of whether particular acquisition expenses should 
be capitalized or expensed. This commenter posited a scenario in which 
the IRS disallowed a deduction because of a disagreement over whether 
carpeting should be capitalized as part of furniture and fixtures or as 
part of the basis in the building, because the determination about how 
to capitalize that item impacts the relevant basis calculation.
    The Treasury Department and the IRS note that the certified 
historic structure exception in section 170(h)(7)(E) and

[[Page 54308]]

Sec.  1.170A-14(n)(4) provides that those qualified conservation 
contributions are not subject to the Disallowance Rule. Under section 
170(f)(19) and proposed Sec.  1.170A-16(f)(6), however, any deduction 
will be disallowed if the amount of the contribution exceeds 2.5 times 
the sum of the relevant bases and the reporting requirements are not 
followed. The commenter's hypothetical is unrealistic because the only 
way the capitalization dispute would result in disallowance under 
section 170(h)(7) or section 170(f)(19) would be if the capitalization 
disagreement resulted in the contribution exceeding 2.5 times the sum 
of the relevant bases and the taxpayer failed to comply with the 
section 170(f)(19) reporting requirements.
    The commenter stated that, rather than using relevant basis, the 
IRS should implement an alternative reporting regime that would include 
``Valuation Assumptions'' and ``Qualified Appraisal Information.'' To 
address valuation assumptions, the commenter suggested a ``Critical 
Information Summary for Historic Preservation Easement Appraisals.'' 
The commenter hoped that this proposal would make it much more 
efficient to determine compliance with the existing requirements and to 
find the aspects of the appraisal that need additional review.
    The second part of the commenter's reporting regime included a 
Qualified Appraisal Checklist, which the commenter suggested would 
serve as a central checklist for taxpayers to report adherence to 
section 170(f)(11)(E)(ii)(II) \8\ and several requirements in the 
section 170 regulations. The commenter stated that adopting such a 
checklist would be permissible because the commenter interprets section 
170(f)(19)(A)(ii) as ``giving the Secretary wide discretion in what 
information to require.''
---------------------------------------------------------------------------

    \8\ Section 170(f)(11)(E)(ii)(ll) requires the appraiser to 
regularly perform appraisals for which the individual receives 
compensation. The commenter seems to imply that the Qualified 
Appraisal Checklist more broadly satisfies the requirements of 
section 170(f)(11)(E) and corresponding regulations.
---------------------------------------------------------------------------

    The Treasury Department and the IRS note that section 170(f)(19)(B) 
requires that the taxpayer compute relevant basis, as defined in 
section 170(h)(7), to determine if the taxpayer is required to report 
under section 170(f)(19)(A). In other words, although the statute 
grants authority for the Treasury Department and the IRS to require 
reporting of additional information, the disallowance rule in section 
170(f)(19) for failure to report required information depends on 
whether the amount of the certified historic structure contribution 
exceeds 2.5 times the sum of the relevant bases, as defined in section 
170(h)(7). Accordingly, the Treasury Department and the IRS decline to 
adopt the commenter's suggestion to replace the relevant basis 
calculation required under section 170(f)(19)(B)(iii) with this 
checklist. As noted in the preamble to the proposed regulations, the 
Treasury Department and the IRS intend to issue future guidance 
addressing section 170(f)(19)(A)(ii).
3. Reporting Requirements for Certified Historic Structure 
Contributions That Also Satisfy Another Exception to the Disallowance 
Rule
    As described above, the proposed regulations required the computing 
and reporting of relevant basis with respect to all contributions that 
satisfy the certified historic structure exception. The proposed 
regulations generally did not require the computation or reporting of 
relevant basis with respect to contributions that satisfied either the 
three-year holding period exception or the family pass-through entity 
exception. However, in a situation in which a contribution satisfies 
both the certified historic structure exception and one of the other 
exceptions, the proposed regulations did require the computing and 
reporting of relevant basis. In addition, under proposed Sec.  1.170A-
16(f), if the amount of the certified historic structure contribution 
or allocated portion exceeded 2.5 times the sum of the relevant bases, 
then section 170(f)(19) would disallow any deduction unless the 
reporting requirements of proposed Sec.  1.170A-16(f) were satisfied.
    One commenter stated that computation and reporting of relevant 
basis should not be required with respect to a contribution that 
satisfies both the certified historic structure exception and one of 
the other exceptions. The commenter opined that the rationale for the 
certified historic structure exception relates to the capital needs of 
operating buildings and not its form of ownership. The commenter opined 
that a qualified conservation contribution does not present 
opportunities for abusive arrangements if the form of ownership 
qualifies for the three-year holding period exception or the family 
pass-through entity exception. The commenter further argued that, had 
Congress been concerned about reporting for the three-year holding 
period exception or the family pass-through entity exception, Congress 
would have imposed a standalone reporting requirement for those 
exceptions. The commenter suggested that requiring participants in the 
other two exceptions to follow the reporting requirements for certified 
historic structures may serve as a deterrent to investment in certified 
historic structures or as a deterrent to protecting certified historic 
structures through a qualified conservation contribution.
    The Treasury Department and the IRS do not adopt this comment. 
Congress drafted section 170(h)(7) so that a contribution meeting any 
of the three statutory exceptions in section 170(h)(7)(C), (D), or (E) 
is not subject to the Disallowance Rule. In contrast, Congress drafted 
the reporting requirements in section 170(f)(19) to apply to all 
certified historic structure contributions in excess of 2.5 times the 
sum of the relevant bases, without regard to whether the contribution 
satisfies the three-year holding period exception or the family pass-
through exception. Similarly, although section 170(h)(7)(C) and (D) 
provide exceptions to the Disallowance Rule, they do not provide an 
exception to the reporting requirements of section 170(f)(19). 
Accordingly, it would not be consistent with the language or purposes 
of section 170(f)(19) and (h)(7) to exempt any certified historic 
structure contributions from section 170(f)(19). In addition, to ensure 
compliance with section 170(f)(19), it is necessary that relevant basis 
be reported for all certified historic structure contributions. Thus, 
these final regulations adopt Sec.  1.170A-16(d)(3)(viii), 
(f)(4)(iii)(B), and (f)(6) as proposed with minor non-substantive 
changes.
    For clarity, these final regulations modify the recordkeeping 
requirements for allocation of modified basis found in proposed Sec.  
1.170A-14(m)(6). As proposed, contributing partnerships, contributing S 
corporations, upper-tier partnerships, and upper-tier S corporations 
must maintain dated, written statements in their books and records by 
the due date, including extensions, of their Federal income tax 
returns, substantiating the computation of each ultimate member's 
adjusted basis, modified basis, and relevant basis, but these 
statements need not be maintained (nor does modified basis or relevant 
basis need to be computed) with respect to contributions that meet an 
exception in Sec.  1.170A-14(n)(2) or (3). These final regulations 
clarify that these statements must be maintained (and modified basis 
and relevant basis must be computed) with respect to all contributions 
that meet the certified historic structure exception in Sec.  1.170A-
14(n)(4), regardless of whether such contributions also meet an

[[Page 54309]]

exception in Sec.  1.170A-14(n)(2) or (3). Accordingly, these 
regulations finalize Sec.  1.170A-14(m)(6) with a clarification to the 
second sentence, which now provides that these statements need not be 
maintained (nor does modified basis or relevant basis need to be 
computed) with respect to contributions that meet an exception in Sec.  
1.170A-14(n)(2) or (3), unless the contribution also meets the 
exception in Sec.  1.170A-14(n) (in which case these statements need to 
be maintained and modified basis and relevant basis need to be 
computed).

VI. Other Comments

    Commenters also addressed: (1) the proposed regulations' 
consistency with the Federal government's position on climate action, 
(2) the ``no inference'' paragraph in the proposed regulations, (3) 
valuation of qualified conservation contributions, and (4) interaction 
of the Disallowance Rule with the rules of section 1011(b) of the Code.
A. Consistency With the Federal Government's Position on Climate Action
    One commenter stated that the proposed regulations evidenced an 
approach to land conservation that is inconsistent with the Federal 
government's position regarding climate action as outlined at the 2023 
United Nations Climate Change Conference (COP28).
    The Treasury Department and the IRS acknowledge the important role 
of climate action, land conservation, and qualified conservation 
contributions. Nevertheless, Congress enacted section 170(f)(19) and 
(h)(7) because of concerns regarding abusive transactions and inflated 
claims. See, e.g., S. Committee on Finance, Comm. Print 116-44, 
Syndicated Conservation-Easement Transactions, 116th Cong., 2nd Sess. 
(2020). The regulations under Sec.  1.170A-14 implement the 
Disallowance Rule.
B. No Inference
    Section 605(c)(2) of the SECURE 2.0 Act states that no inference is 
intended as to the appropriate treatment of any contribution for which 
a deduction is not disallowed by reason of section 170(h)(7). As 
explained in the preamble to the proposed regulations, some 
practitioners have taken the position that section 170(h)(7) operates 
as a ``safe harbor.'' According to these practitioners, a qualified 
conservation contribution that is not disallowed by the Disallowance 
Rule is somehow immune to a challenge on other grounds, including 
failure to comply with other rules under section 170 and overvaluation 
of the contribution. The preamble to the proposed regulations stated 
that such a position is baseless and contradicted by the statutory 
language. To clarify this issue, proposed Sec.  1.170A-14(j)(5) 
provided that there is no presumption that a qualified conservation 
contribution that is not a disallowed qualified conservation 
contribution is compliant with section 170, any other section of the 
Code, the regulations, or any other guidance thereunder. It also 
provided that compliance with section 170(h)(7) and proposed Sec.  
1.170A-14(j) through (n) is not a safe harbor for purposes of any other 
provision of law, including the other requirements of section 170 and 
the value of the contribution. Such transactions are subject to 
adjustment or disallowance for any other reason, including failure to 
satisfy the requirements of section 170 or the overvaluation of the 
contribution; for example, failure to properly execute Form 8283, 
violation of the partnership anti-abuse rule of Sec.  1.701-2, lack of 
economic substance, or other rules or judicial doctrines. In addition, 
compliance with proposed Sec.  1.170A-14(j) through (n) would not 
preclude the application of any penalty, including penalties for 
valuation misstatement, negligence, and fraud. Proposed Sec.  1.170A-
14(j)(5) also provided that taxpayers who engage in such transactions 
may be required to disclose, under Sec.  1.6011-4, the transactions as 
listed transactions.
    One commenter requested that the IRS delete proposed Sec.  1.170A-
14(j)(5). The commenter stated that paragraph does not add any value to 
the substance of the proposed regulations and is ``inappropriately 
hostile toward donors of qualified conservation contributions.''
    The Treasury Department and the IRS do not agree with this comment. 
Proposed Sec.  1.170A-14(j)(5) implements section 605(c)(2) of the 
SECURE 2.0 Act and provides further detail and clarification about the 
interaction between section 605(c)(2) of the SECURE 2.0 Act and the 
other rules governing qualified conservation contributions. Moreover, 
as explained in the preamble to the proposed regulations, the rule in 
proposed Sec.  1.170A-14(j)(5) addresses positions that some 
practitioners have actually taken. Accordingly, these final regulations 
retain Sec.  1.170A-14(j)(5) with minor non-substantive changes.
C. Valuation of Qualified Conservation Contributions
    One commenter expressed concern that the proposed regulations do 
not address the valuation of donated property, especially real 
property, nor do they address fraudulent appraisal practices.
    The Treasury Department and the IRS agree that overvaluation is an 
important facet of abusive charitable contributions of interests in 
real property. However, any guidance on valuation would be outside the 
scope of these final regulations, which are focused on the Disallowance 
Rule, section 170(f)(19), and reporting requirements for noncash 
charitable contributions. The Treasury Department and the IRS have 
challenged and will continue to challenge fraudulent appraisal 
practices and overvaluation.
D. Interaction With the Rules of Section 1011(b)
    Section 1011(b) provides that, if a deduction is allowable under 
section 170 by reason of a sale, then the adjusted basis for 
determining the gain from such sale is that portion of the adjusted 
basis which bears the same ratio to the adjusted basis as the amount 
realized bears to the fair market value of the property. The proposed 
regulations do not address section 1011(b). One commenter asked about 
the interaction of section 1011(b) with the Disallowance Rule. 
Specifically, the commenter asked whether the actual fair market value 
of the qualified conservation contribution or the ``capped amount'' 
under section 170(h)(7) should be used in applying section 1011(b).
    First, the Treasury Department and the IRS disagree that section 
170(h)(7) is a ``capped amount;'' it is a Disallowance Rule for certain 
qualified conservation contributions by pass-through entities.
    Second, by its terms, section 1011(b) applies only if a deduction 
is allowable under section 170 by reason of a sale. Therefore, if a 
contribution is disallowed, section 1011(b) would not apply.
    Third, even in situations in which section 1011(b) could apply, the 
application of section 1011(b) is outside the scope of these final 
regulations, and these final regulations do not address section 
1011(b). The Treasury Department and the IRS note, however, that the 
computation of adjusted basis for determining gain from a sale 
described in section 1011(b) refers to the fair market value of the 
property, not the amount of the allowable deduction under section 170.

Special Analyses

I. Regulatory Planning and Review

    Pursuant to the Memorandum of Agreement, Review of Treasury

[[Page 54310]]

Regulations under Executive Order 12866 (June 9, 2023), tax regulatory 
actions issued by the IRS are not subject to the requirements of 
section 6 of Executive Order 12866, as amended. Therefore, a regulatory 
impact assessment is not required.

II. Paperwork Reduction Act

    The Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520) generally 
requires that a Federal agency obtain the approval of the Office of 
Management and Budget (OMB) before collecting information from the 
public, whether such collection of information is mandatory, voluntary, 
or required to obtain or retain a benefit. An agency may not conduct or 
sponsor, and a person is not required to respond to, a collection of 
information unless the collection of information displays a valid 
control number.
    The collection of information contained in these final regulations 
is reflected in the collection of information for Form 8283, Noncash 
Charitable Contributions, and Schedule K-1 for Forms 1065, U.S. Return 
of Partnership Income, and 1120-S, U.S. Income Tax Return for an S 
corporation, that have been reviewed and approved by the Office of 
Management and Budget in accordance with the Paperwork Reduction Act 
(44 U.S.C. 3507(c)) under control numbers 1545-0074 and 1545-0123. The 
preamble to the proposed regulations stated that the estimated burden 
for taxpayers filing Form 8283 under OMB control number 1545-0074 is 
nineteen minutes for recordkeeping, twenty-nine minutes for learning 
about the law or the form, one hour and four minutes for preparing the 
form, and thirty-four minutes for copying, assembling, and sending the 
form to the IRS.
    Two commenters raised concerns with the taxpayer burden. One 
commenter stated that the burden to learn these rules was unreasonable. 
Another commenter stated that the proposed estimated time burdens for 
Form 8283 drastically underestimated the time necessary for a taxpayer 
to understand and apply the regulations. As explained in this preamble, 
these regulations are promulgated under the authority of section 
170(h)(7) and other provisions in the Code, are consistent with the 
language and purposes of section 170(f)(19) and (h)(7), and the 
Treasury Department and the IRS have determined that they are not more 
burdensome than necessary. Accordingly, the burden imposed by these 
final regulations is reasonable. However, the Treasury Department and 
the IRS will evaluate the estimated time for a taxpayer to understand 
and apply the regulations and will reflect any revisions in the Form 
8283 burden estimates. To the extent there is a change in burden as a 
result of these regulations, the change in burden will be reflected in 
the updated burden estimates for the Form 8283 and Schedule K-1 for 
Forms 1065 and 1120-S. The requirement to maintain records to 
substantiate information on Form 8283 and Schedule K-1 for Forms 1065 
and 1120-S is already contained in the burden estimates associated with 
the control number for the forms and remains unchanged.

III. Regulatory Flexibility Act

    The Secretary of the Treasury hereby certifies that these final 
regulations will not have a significant economic impact on a 
substantial number of small entities pursuant to the Regulatory 
Flexibility Act (5 U.S.C. chapter 6). These final regulations affect 
partnerships and S corporations that claim qualified conservation 
contributions as well as partners and S corporation shareholders that 
receive a distributive share or pro rata share of a noncash charitable 
contribution. Although data is not readily available about the number 
of small entities that are potentially affected by this rule, it is 
possible that a substantial number of small entities may be affected.
    The impact of these final regulations can be described in the 
following five categories.
    First, Sec.  1.170A-14(j) through (n) provides guidance in applying 
section 170(h)(7), including providing definitions, formulas for the 
required calculations, and examples to help ensure the effective 
application of section 170(h)(7), and Sec. Sec.  1.706-3 and 1.706-
4(e)(2)(xiii) provide special rules for allocating qualified 
conservation contributions. Even assuming that these provisions affect 
a substantial number of small entities, they will not have a 
significant economic impact. Section 170(h)(7) is self-executing and 
the statute imposes the burden of calculating relevant basis and 
applying the Disallowance Rule. Because these final regulations are 
focused on providing definitional and computational guidance related to 
section 170(h)(7), their economic impact is expected to be minimal.
    Second, Sec.  1.170A-14(m)(6) generally requires contributing 
partnerships, contributing S corporations, upper-tier partnerships, and 
upper-tier S corporations to maintain dated, written statements in 
their books and records, by the due date, including extensions, of 
their Federal income tax returns, substantiating the computation of 
each ultimate member's adjusted basis, modified basis, and relevant 
basis. Even assuming that this provision affects a substantial number 
of small entities, it will not have a significant economic impact 
because partnerships and S corporations generally need to create these 
statements by the due date of their Federal income tax returns to 
ensure that they have complied with the requirements of section 
170(h)(7) and (f)(19), which are self-executing. Therefore, this 
provision simply requires partnerships and S corporations to maintain 
something that they generally have already created.
    Third, Sec.  1.170A-16(d)(3)(viii) requires the Form 8283 filed by 
contributing partnerships and contributing S corporations to include 
the sum of each ultimate member's relevant basis. The existing 
regulations under Sec.  1.170A-16 already require these entities to 
file Form 8283. Even assuming that this provision affects a substantial 
number of small entities, it will not have a significant economic 
impact because it simply requires contributing partnerships and 
contributing S corporations to put a small amount of additional 
information, which section 170(h)(7) and (f)(19) requires them to 
determine, on a form they are already required to file.
    Fourth, Sec.  1.170A-16(f)(6) requires a partnership or S 
corporation to file a completed Form 8283 to be considered to satisfy 
the requirements of section 170(f)(19)(A). Even assuming that this 
provision affects a substantial number of small entities, it will not 
have a significant economic impact because it simply requires 
contributing partnerships and contributing S corporations to complete a 
form they are already required to file.
    Fifth, Sec.  1.170A-16(f)(4)(iii) requires all partners and 
shareholders of S corporations who receive an allocation of a noncash 
charitable contribution to file a separate Form 8283. Many of these 
partners and shareholders will be individuals, not small entities. 
However, even assuming that this provision affects a substantial number 
of small entities, it will not have a significant economic impact. The 
partnership or S corporation will provide the partner or shareholder 
with all, or substantially all, of the information to be reported on 
the separate Form 8283; this information will be contained either on 
the partnership's or S corporation's Form 8283 or the Schedule K-1 
issued to the partner or shareholder. Accordingly, in most cases, 
partners and shareholders will simply be transcribing information

[[Page 54311]]

provided to them onto the separate Form 8283.
    For the reasons stated, a regulatory flexibility analysis under the 
Regulatory Flexibility Act is not required. Pursuant to section 7805(f) 
of the Code, the proposed rule preceding these final regulations was 
submitted to the Chief Counsel for Advocacy of the Small Business 
Administration for comment on its impact on small business. No comments 
were received from the Chief Counsel for Advocacy of the Small Business 
Administration.

IV. Unfunded Mandates Reform Act

    Section 202 of the Unfunded Mandate Reform Act of 1995 (UMRA) 
requires that agencies assess anticipated costs and benefits and take 
certain other actions before issuing a final rule that includes any 
Federal mandate that may result in expenditures in any one year by a 
State, local, or Tribal government, in the aggregate, or by the private 
sector, of $100 million (updated annually for inflation). These final 
regulations do not include any Federal mandate that may result in 
expenditures by State, local, or Tribal governments or by the private 
sector in excess of that threshold.

V. Executive Order 13132: Federalism

    Executive Order 13132 (Federalism) prohibits an agency from 
publishing any rule that has federalism implications if the rule either 
imposes substantial, direct compliance costs on State and local 
governments, and is not required by statute, or preempts State law, 
unless the agency meets the consultation and funding requirements of 
section 6 of the Executive order. These final regulations do not have 
federalism implications and do not impose substantial, direct 
compliance costs on State and local governments or preempt State law 
within the meaning of the Executive order.

VI. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175 (Consultation and Coordination With Indian 
Tribal Governments) prohibits an agency from publishing any rule that 
has Tribal implications if the rule either imposes substantial, direct 
compliance costs on Indian Tribal governments, and is not required by 
statute, or preempts Tribal law, unless the agency meets the 
consultation and funding requirements of section 5 of the Executive 
order. These final regulations do not have substantial direct effects 
on one or more federally recognized Indian tribes and does not impose 
substantial direct compliance costs on Indian Tribal governments within 
the meaning of the Executive order.

VII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
the Office of Information and Regulatory Affairs designated this rule 
as not a ``major rule,'' as defined by 5 U.S.C. 804(2).

Par. 2. Section 1.170A-14 is amended by revising paragraphs (a) and (j) 
and adding paragraphs (k) through (o) to read as follows:


Sec.  1.170A-14   Qualified conservation contributions.

    (a) Qualified conservation contributions. A deduction under section 
170 of the Internal Revenue Code (Code) is generally not allowed for a 
charitable contribution of any interest in property that consists of 
less than the donor's entire interest in the property other than 
certain transfers in trust (see Sec.  1.170A-6 relating to charitable 
contributions in trust and Sec.  1.170A-7 relating to contributions not 
in trust of partial interests in property). However, a deduction may be 
allowed under section 170(f)(3)(B)(iii) for the value of a qualified 
conservation contribution if the requirements of this section are met 
and the contribution is not a disallowed qualified conservation 
contribution within the meaning of paragraph (j) of this section. A 
qualified conservation contribution is the contribution of a qualified 
real property interest to a qualified organization exclusively for 
conservation purposes. To be eligible for a deduction under section 
170(h) and this section, the conservation purpose must be protected in 
perpetuity.
* * * * *
    (j) Disallowance of certain deductions for contributions by 
partnerships and S corporations that exceed 2.5 times the sum of the 
relevant bases--(1) In general. This paragraph (j) applies the rules of 
section 170(h)(7), which disallow a deduction for certain qualified 
conservation contributions, as defined in section 170(h)(1) and this 
section, made by, or allocated to, partnerships or S corporations (as 
defined in section 1361(a)(1) of the Code) if the amount of the 
qualified conservation contribution exceeds 2.5 times the sum of the 
relevant bases as determined by this paragraph (j) and paragraphs (k) 
through (m) of this section (Disallowance Rule). The Disallowance Rule 
does not apply to qualified conservation contributions made directly by 
landowners that are not pass-through entities, such as individuals or C 
corporations. See paragraph (n) of this section for certain exceptions. 
See paragraph (j)(3) of this section for definitions of terms used in 
this paragraph (j) and paragraphs (k) through (n) of this section.
    (2) Application--(i) Contributing partnerships and contributing S 
corporations. Except as provided in paragraph (n) of this section, a 
qualified conservation contribution by a contributing partnership or a 
contributing S corporation is a disallowed qualified conservation

[[Page 54312]]

contribution if the amount of the qualified conservation contribution 
exceeds 2.5 times the sum of each of the contributing partnership's or 
contributing S corporation's ultimate member's relevant basis as 
determined under this paragraph (j) and paragraphs (k) through (m) of 
this section.
    (ii) Upper-tier partnerships and upper-tier S corporations. Except 
as provided in paragraph (n) of this section, an allocated portion 
received by an upper-tier partnership or upper-tier S corporation is a 
disallowed qualified conservation contribution if either the 
contribution is a disallowed qualified conservation contribution with 
respect to the partnership that allocated the allocated portion to the 
upper-tier partnership or upper-tier S corporation, or such allocated 
portion exceeds 2.5 times the sum of each of that upper-tier 
partnership's or upper-tier S corporation's ultimate member's relevant 
basis as determined under this paragraph (j) and paragraphs (k) through 
(m) of this section.
    (iii) Partner or S corporation shareholder claiming an inconsistent 
amount. If a partner or S corporation shareholder claims an amount of 
qualified conservation contribution that is inconsistent with and 
greater than the partner's distributive share or S corporation 
shareholder's pro rata share of qualified conservation contribution 
reported to the partner or S corporation shareholder by the partnership 
or S corporation, predicated on a position that the partnership's or S 
corporation's qualified conservation contribution was a greater amount 
than the amount claimed by the partnership or S corporation, and the 
qualified conservation contribution would have been a disallowed 
qualified conservation contribution if the partnership or S corporation 
had actually claimed that greater amount, then the partner's or S 
corporation shareholder's claimed qualified conservation contribution 
is a disallowed qualified conservation contribution.
    (3) Definitions. The following definitions apply for purposes of 
this paragraph (j) and paragraphs (k) through (n) of this section:
    (i) Allocated portion. In the case of an upper-tier partnership or 
upper-tier S corporation that receives, directly or indirectly, a 
distributive share of a qualified conservation contribution, the phrase 
allocated portion means the amount of such distributive share.
    (ii) Amount of qualified conservation contribution. The amount of a 
contributing partnership's or contributing S corporation's qualified 
conservation contribution is the amount claimed as a qualified 
conservation contribution on the return of the contributing partnership 
or contributing S corporation for the taxable year in which the 
contribution is made. If the contributing partnership or contributing S 
corporation files an amended return or administrative adjustment 
request under section 6227 of the Code claiming a higher amount with 
respect to the qualified conservation contribution, the rules of this 
section must be re-applied with respect to such higher amount to 
determine the application of section 170(h)(7) and this section; for 
example, if a contributing S corporation's original return claims a 
qualified conservation contribution that does not exceed 2.5 times the 
sum of the relevant bases, and the S corporation subsequently files an 
amended return claiming a higher amount with respect to the qualified 
conservation contribution that does exceed 2.5 times the sum of the 
relevant bases, then the entire amount of the qualified conservation 
contribution is a disallowed qualified conservation contribution 
(unless one of the exceptions in paragraph (n) of this section 
applies). If the contributing partnership or contributing S corporation 
files an amended return or timely administrative adjustment request 
under section 6227 claiming a lower amount with respect to the 
qualified conservation contribution, the rules of this section will be 
re-applied with respect to such lower amount to determine the 
application of section 170(h)(7) and this section if and only if the 
amended return or timely administrative adjustment request is filed 
before the contributing partnership or contributing S corporation is 
put on notice of an IRS examination with respect to the qualified 
conservation contribution. A contributing partnership or contributing S 
corporation is considered to be on notice after the earlier of--
    (A) The date the contributing partnership or contributing S 
corporation is first contacted by the Internal Revenue Service in 
connection with any examination of a return that relates to the 
qualified conservation contribution; or
    (B) The date any person is first contacted by the Internal Revenue 
Service concerning an examination of that person under section 6700 
(relating to the penalty for promoting abusive tax shelters) for an 
activity that relates to the qualified conservation contribution.
    (iii) Contributing partnership. The term contributing partnership 
means a partnership that makes a qualified conservation contribution.
    (iv) Contributing S corporation. The term contributing S 
corporation means an S corporation that makes a qualified conservation 
contribution.
    (v) Direct interest. The term direct interest refers to an 
ownership interest in a contributing partnership, upper-tier 
partnership, contributing S corporation, or upper-tier S corporation 
that is held directly, or through an entity disregarded as separate 
from its owner for Federal income tax purposes, a qualified subchapter 
S subsidiary as defined in section 1361(b)(3), or through a grantor 
trust (under subpart E of part 1 of subchapter J of chapter 1 of the 
Code). In the case of a partner that is a C corporation (as defined in 
section 1361(a)(2)), non-grantor trust, or an estate, or an S 
corporation shareholder that is a non-grantor trust or an estate, the 
direct interest in the partnership or S corporation, as applicable, is 
held by the C corporation, non-grantor trust, or estate; the C 
corporation's shareholders, trust beneficiaries, and estate 
beneficiaries are not considered to hold any interest in the 
partnership or S corporation, as applicable, for purposes of this 
paragraph (j) and paragraphs (k) through (n) of this section.
    (vi) Directly. An ownership interest is held directly if it is not 
held through one or more upper-tier partnerships or upper-tier S 
corporations. A distributive share or pro rata share of a qualified 
conservation contribution is received directly if it does not pass 
through one or more upper-tier partnerships or upper-tier S 
corporations.
    (vii) Disallowed qualified conservation contribution. The term 
disallowed qualified conservation contribution means a qualified 
conservation contribution or allocated portion for which no deduction 
is allowed pursuant to section 170(h)(7) and this paragraph (j).
    (viii) Indirect interest. The term indirect interest refers to an 
ownership interest in a contributing partnership, contributing S 
corporation, upper-tier partnership, or upper-tier S corporation held 
through an upper-tier S corporation or one or more upper-tier 
partnerships.
    (ix) Indirectly. An ownership interest is held indirectly if it is 
held through one or more upper-tier partnerships or upper-tier S 
corporations. A distributive share or pro rata share of a qualified 
conservation contribution is received indirectly if it passes through 
one or more upper-tier partnerships or upper-tier S corporations.
    (x) Ultimate member. The term ultimate member means, with respect 
to any partnership or S corporation, any partner (that is not itself a 
partnership

[[Page 54313]]

or S corporation) or S corporation shareholder that receives a 
distributive share or pro rata share, directly or indirectly, of a 
qualified conservation contribution. Thus, ultimate members will either 
be partners holding a direct interest in a partnership, which may be 
the contributing partnership or an upper-tier partnership, or 
shareholders holding a direct interest in an S corporation, which may 
be the contributing S corporation or an upper-tier S corporation. 
Upper-tier S corporations and upper-tier partnerships themselves are 
not considered ultimate members.
    (xi) Upper-tier partnership. The term upper-tier partnership means 
a partnership that receives an allocated portion.
    (xii) Upper-tier S corporation. The term upper-tier S corporation 
means an S corporation that receives an allocated portion.
    (4) Effect of Disallowance Rule--(i) If the Disallowance Rule 
applies to a contributing partnership or contributing S corporation. If 
a contributing partnership's or contributing S corporation's qualified 
conservation contribution is a disallowed qualified conservation 
contribution under this paragraph (j), then:
    (A) Any upper-tier partnership's or upper-tier S corporation's 
allocated portion of such contribution is a disallowed qualified 
conservation contribution, regardless of whether such allocated portion 
exceeds 2.5 times the sum of each of the upper-tier partnership's or 
upper-tier S corporation's ultimate member's relevant basis; and
    (B) No person (whether holding a direct or indirect interest in 
such contributing partnership or contributing S corporation) may claim 
a deduction under any provision of the Code with respect to any amount 
of such disallowed qualified conservation contribution, regardless of 
whether that person's distributive share or pro rata share of the 
disallowed qualified conservation contribution exceeds 2.5 times its 
relevant basis.
    (ii) If the Disallowance Rule does not apply to a contributing 
partnership or contributing S corporation. If a contributing 
partnership's or contributing S corporation's qualified conservation 
contribution is not a disallowed qualified conservation contribution 
under this paragraph (j), then:
    (A) The distributive share or pro rata share of any ultimate member 
holding a direct interest in the contributing partnership or 
contributing S corporation is not a disallowed qualified conservation 
contribution; and
    (B) Any upper-tier partnership or upper-tier S corporation that 
receives an allocated portion of such qualified conservation 
contribution must separately apply the rules of section 170(h)(7) and 
this paragraph (j) and paragraphs (k) through (m) of this section to 
determine whether that upper-tier partnership's or upper-tier S 
corporation's allocated portion is a disallowed qualified conservation 
contribution.
    (iii) If the Disallowance Rule applies to an upper-tier partnership 
or an upper-tier S corporation. If an upper-tier partnership's or 
upper-tier S corporation's allocated portion is a disallowed qualified 
conservation contribution under this paragraph (j), then:
    (A) Any subsequent upper-tier partnership's or upper-tier S 
corporation's allocated portion of such allocated portion is a 
disallowed qualified conservation contribution, regardless of whether 
the subsequent upper-tier partnership's or upper-tier S corporation's 
allocated portion exceeds 2.5 times the sum of each of the subsequent 
upper-tier partnership's or upper-tier S corporation's ultimate 
member's relevant basis; and
    (B) No person holding a direct or indirect interest in that upper-
tier partnership or upper-tier S corporation may claim a deduction 
under any provision of the Code with respect to any amount of that 
upper-tier partnership's or upper-tier S corporation's allocated 
portion, regardless of whether that person's distributive share or pro 
rata share of the allocated portion exceeds 2.5 times its relevant 
basis. However, this does not affect the application of this paragraph 
(j) and paragraphs (k) through (m) of this section to another partner 
of the contributing partnership; for example, if the qualified 
conservation contribution is not a disallowed qualified conservation 
contribution with respect to the contributing partnership, then the 
distributive share of such contribution of an ultimate member holding a 
direct interest in the contributing partnership is not a disallowed 
qualified conservation contribution, notwithstanding that the qualified 
conservation contribution is a disallowed qualified conservation 
contribution with respect to one or more upper-tier partnerships or 
upper-tier S corporations.
    (iv) If the Disallowance Rule does not apply to an upper-tier 
partnership or upper-tier S corporation. If an upper-tier partnership's 
or upper-tier S corporation's allocated portion is not a disallowed 
qualified conservation contribution under this paragraph (j), then:
    (A) The distributive share or pro rata share of such allocated 
portion of any ultimate member holding a direct interest in the upper-
tier partnership or upper-tier S corporation is not a disallowed 
qualified conservation contribution; and
    (B) Any subsequent upper-tier partnership or upper-tier S 
corporation that receives an allocated portion of such allocated 
portion must separately apply the rules of section 170(h)(7) and this 
paragraph (j) and paragraphs (k) through (m) of this section to 
determine whether that subsequent upper-tier partnership's or upper-
tier S corporation's allocated portion is treated as a disallowed 
qualified conservation contribution.
    (5) No inference. There is no presumption that a qualified 
conservation contribution that is not a disallowed qualified 
conservation contribution as defined in paragraph (j)(3)(vii) of this 
section is compliant with section 170, any other section of the Code, 
the regulations, or any other guidance. Compliance with section 
170(h)(7) and this paragraph (j) and paragraphs (k) through (n) of this 
section is not a safe harbor for purposes of any other provision of law 
or with respect to the value of the contribution. Such transactions are 
subject to adjustment or disallowance for any other reason, including 
failure to satisfy the other requirements of section 170 or 
overvaluation of the contribution. In addition, taxpayers who engage in 
such transactions may be required to disclose under Sec.  1.6011-4 the 
transactions as listed transactions.
    (6) Examples. The following examples illustrate the rules of this 
paragraph (j). For these three examples in this paragraph (j)(6), 
assume that the partnership allocations comply with the rules of 
subchapter K of chapter 1 of the Code, and that the exceptions in 
paragraph (n) of this section do not apply.
    (i) Example 1: Disallowed qualified conservation contribution--(A) 
Facts. A, an individual, and B, a C corporation, form AB Partnership, a 
partnership for Federal income tax purposes. AB Partnership acquires 
real property. Two years later, AB Partnership makes a qualified 
conservation contribution with respect to the property and claims a 
contribution of $100X on its return. AB Partnership allocates the 
contribution equally to A and B. A's relevant basis is $30X, and B's 
relevant basis is $8X.

[[Page 54314]]

    (B) Analysis. A and B are the ultimate members of AB Partnership 
because they each receive a distributive share of the qualified 
conservation contribution and are not partnerships or S corporations. 
The claimed amount of AB Partnership's qualified conservation 
contribution is $100X, which exceeds 2.5 times the sum of A's and B's 
relevant bases, which is $95X ($95X = 2.5 x (A's $30X relevant basis + 
B's $8X relevant basis)). Therefore, AB Partnership's contribution is a 
disallowed qualified conservation contribution. No person may claim any 
deduction with respect to this contribution, even though A's $50X 
distributive share of the contribution does not exceed 2.5 times A's 
$30X relevant basis.
    (ii) Example 2: Not a disallowed qualified conservation 
contribution--(A) Facts. Individuals C and D form CD Partnership, a 
partnership for Federal income tax purposes. CD Partnership acquires 
real property. Two years later, CD Partnership makes a qualified 
conservation contribution with respect to the property and claims a 
contribution of $100X on its return. CD Partnership allocates the 
contribution $5X to C and $95X to D. C's relevant basis is $6X, and D's 
relevant basis is $34X.
    (B) Analysis. C and D are the ultimate members of CD Partnership 
because they each receive a distributive share of the qualified 
conservation contribution and are not partnerships or S corporations. 
The claimed amount of CD Partnership's qualified conservation 
contribution is $100X, which does not exceed 2.5 times the sum of C's 
and D's relevant bases, which is also $100X ($100X = 2.5 x (C's $6X 
relevant basis + D's $34X relevant basis)). Therefore, CD Partnership's 
contribution is not a disallowed qualified conservation contribution 
(that is, not disallowed by section 170(h)(7) and this paragraph (j)) 
with respect to CD Partnership, C, or D, even though D's $95X 
distributive share of the contribution exceeds 2.5 times D's $34X 
relevant basis.
    (iii) Example 3: Tiered partnerships--(A) Facts. Individuals E and 
F form UTP Partnership, a partnership for Federal income tax purposes. 
UTP Partnership and G, a C corporation, form LTP Partnership, a 
partnership for Federal income tax purposes. LTP Partnership acquires 
real property. Two years later, LTP Partnership makes a qualified 
conservation contribution with respect to the property and claims a 
contribution of $100X on its return. LTP Partnership allocates the 
contribution $5X to G and $95X to UTP Partnership. UTP Partnership 
allocates its $95X portion of the contribution $45X to E and $50X to F. 
G's relevant basis is $10X, E's relevant basis is $11X, and F's 
relevant basis is $21X.
    (B) Analysis for LTP Partnership. The ultimate members of LTP 
Partnership are G, E, and F because they each receive a distributive 
share of the qualified conservation contribution and are not a 
partnership or S corporation. Because UTP Partnership is a partnership, 
it is not an ultimate member of LTP Partnership, even though it 
receives a distributive share of the qualified conservation 
contribution. The amount of LTP Partnership's qualified conservation 
contribution is $100X, which does not exceed 2.5 times the sum of each 
of the ultimate member's relevant basis, which is $105X ($105X = 2.5 x 
(G's $10X relevant basis + E's $11X relevant basis + F's $21X relevant 
basis)). Therefore, LTP Partnership's contribution is not a disallowed 
qualified conservation contribution (that is, is not disallowed by 
section 170(h)(7) and this paragraph (j)) with respect to LTP 
Partnership and G.
    (C) Analysis for UTP Partnership. Because UTP Partnership receives 
an allocated portion, UTP Partnership must apply this paragraph (j) and 
paragraphs (k) through (m) of this section to determine whether its 
allocated portion is a disallowed qualified conservation contribution. 
The ultimate members of UTP Partnership are E and F because they each 
receive a distributive share of UTP Partnership's allocated portion and 
are not partnerships or S corporations. The amount of UTP Partnership's 
allocated portion of LTP Partnership's qualified conservation 
contribution is $95X, which exceeds 2.5 times the sum of E's and F's 
relevant bases, which is $80X ($80X = 2.5 x (E's $11X relevant basis + 
F's $21X relevant basis)). Therefore, UTP Partnership's allocated 
portion of LTP Partnership's contribution is a disallowed qualified 
conservation contribution with respect to UTP Partnership, E, and F. No 
partner of UTP Partnership may claim any deduction with respect to this 
contribution, even though F's $50X distributive share of the 
contribution does not exceed 2.5 times F's $21X relevant basis. This 
does not affect the determination that G's distributive share of the 
contribution is not a disallowed qualified conservation contribution.
    (k) Determination of relevant basis. For purposes of this section, 
the term relevant basis means, with respect to any ultimate member, the 
portion of such ultimate member's modified basis (as determined under 
paragraph (l) of this section) that is allocable (under the rules of 
paragraph (m) of this section) to the portion of the real property with 
respect to which the qualified conservation contribution is made.
    (l) Determination of modified basis--(1) In general. In the case of 
an ultimate member holding a direct interest in a partnership, the 
ultimate member's modified basis is determined by such partnership 
immediately before the qualified conservation contribution is made in 
the manner described in paragraph (l)(2) of this section. In the case 
of an ultimate member holding a direct interest in an S corporation, 
the ultimate member's modified basis is determined by such S 
corporation in the manner described in paragraph (l)(3) of this 
section.
    (2) Partners in partnerships--(i) Computation. For purposes of this 
section, the term modified basis means, with respect to any ultimate 
member that is a direct partner in either a contributing partnership or 
an upper-tier partnership, such ultimate member's adjusted basis in its 
interest in the partnership in which the ultimate member holds a direct 
interest as of the beginning of the first day of the partnership's 
taxable year in which the qualified conservation contribution is made, 
with adjustments as determined under paragraphs (l)(2)(ii) through (vi) 
of this section. However, if the ultimate member was not a partner as 
of the beginning of the first day of the partnership's taxable year in 
which the qualified conservation contribution is made, then the term 
modified basis means such ultimate member's adjusted basis in its 
interest in the partnership immediately after the transaction that 
resulted in the ultimate member becoming a partner, with adjustments as 
determined under paragraphs (l)(2)(ii) through (vi) of this section. 
The adjustments under paragraphs (l)(2)(ii) through (vi) must be made 
in the order in which they are listed.
    (ii) Step 1. First, the computation of modified basis must start 
with the ultimate member's adjusted basis under paragraph (l)(2)(i) of 
this section and then reflect an increase for any contributions made by 
the ultimate member to the partnership during the portion of the year 
commencing with the beginning of the taxable year of the partnership 
and ending immediately prior to the time of day at which the qualified 
conservation contribution is made as provided in section 722 of the 
Code.
    (iii) Step 2. Second, if between the beginning of the partnership's 
taxable year and the time of day at which the qualified conservation 
contribution is made, the ultimate member acquired

[[Page 54315]]

additional interests in the partnership, the amount determined under 
paragraph (l)(2)(ii) of this section must be increased by the ultimate 
member's initial basis in those additional interests. If, between the 
beginning of the partnership's taxable year and the time of day at 
which the qualified conservation contribution is made, the ultimate 
member partially disposed of its interest in the partnership, the 
amount determined under paragraph (l)(2)(ii) of this section must be 
decreased by the ultimate member's basis in the interests disposed of.
    (iv) Step 3. Third, the amount determined under paragraph 
(l)(2)(iii) of this section must be adjusted, as provided in section 
705 of the Code, by the ultimate member's hypothetical distributive 
share of partnership items attributable to the portion of the year 
commencing with the beginning of the taxable year of the partnership 
and ending immediately prior to the time of day at which the qualified 
conservation contribution is made. In making this determination, the 
partnership must apply the rules of Sec.  1.706-4 and apply a 
hypothetical interim closing method to allocate the partnership's items 
attributable to the portion of the year commencing with the beginning 
of the taxable year of the partnership and ending immediately prior to 
the time of day at which the qualified conservation contribution is 
made. The partnership cannot apply any convention in Sec.  1.706-4(c) 
to the hypothetical determination of the partners' distributive shares, 
but rather must perform the calculation as though the determination 
occurred immediately prior to the time of day at which the qualified 
conservation contribution is made. This hypothetical determination of 
the partners' distributive shares is only for purposes of calculating 
modified basis. This paragraph (l) does not require the partnership to 
use the interim closing method with respect to the determination of its 
partners' actual distributive shares of partnership items of income, 
gain, loss, deduction, and credit for the taxable year in which the 
qualified conservation contribution is made or otherwise. See Sec.  
1.706-4 for applicable rules for the determination of a partner's 
distributive share when a partner's interest varies during a 
partnership taxable year.
    (v) Step 4. Fourth, the amount determined under paragraph 
(l)(2)(iv) of this section must be reduced (but not below zero) by any 
distributions made by the partnership to the ultimate member during the 
portion of the year commencing with the beginning of the taxable year 
of the partnership and ending immediately prior to the time of day at 
which the qualified conservation contribution is made as provided in 
section 733 of the Code.
    (vi) Step 5. Fifth, the amount determined under paragraph (l)(2)(v) 
of this section must be reduced by the full amount of the ultimate 
member's share of Sec.  1.752-1 liabilities of any partnership 
(including a lower-tier partnership). The remaining amount is such 
ultimate member's modified basis. Thus, an ultimate member's modified 
basis may be less than zero.
    (3) S corporation shareholder--(i) Computation. For purposes of 
this section, the term modified basis means, with respect to any 
ultimate member that is a shareholder of either a contributing S 
corporation or an upper-tier S corporation, such ultimate member's 
adjusted basis in its shares in the S corporation as of the end of the 
S corporation's taxable year in which the qualified conservation 
contribution is made, with adjustments as determined under paragraphs 
(l)(3)(ii) and (iii) of this section. However, if the ultimate member 
was not a shareholder at the end of the S corporation's taxable year in 
which the qualified conservation contribution is made, then the term 
modified basis means such ultimate member's adjusted basis in its 
shares in the S corporation immediately prior to the transaction that 
terminated its interest in the S corporation, with adjustments as 
determined under paragraphs (l)(3)(ii) and (iii) of this section. 
Modified basis does not include the ultimate member's adjusted basis in 
any indebtedness of the S corporation to the ultimate member. The 
adjustments under paragraphs (l)(3)(ii) and (iii) of this section must 
be made in the order in which they are listed.
    (ii) Step 1. First, the computation of modified basis must start 
with the ultimate member's adjusted basis under paragraph (l)(3)(i) of 
this section, and then reflect an increase for the extent to which the 
ultimate member's adjusted basis reflects a reduction as a result of 
the qualified conservation contribution. Thus, the ultimate member's 
modified basis with respect to a qualified conservation contribution 
does not reflect any reduction for the ultimate member's pro rata share 
of the S corporation's basis in the conservation easement or other 
property contributed in the qualified conservation contribution.
    (iii) Step 2. Second, the amount determined under paragraph 
(l)(3)(ii) of this section must be multiplied by the number of days 
during the S corporation's taxable year in which the ultimate member 
was a shareholder and divided by the total number of days during the S 
corporation's taxable year. The resulting amount is such ultimate 
member's modified basis.
    (4) Examples. The following examples illustrate the provisions of 
this paragraph (l). For the four examples in this paragraph (l)(4), 
assume that the partnership allocations comply with the rules of 
subchapter K of chapter 1 of the Code and the exceptions in paragraph 
(n) of this section do not apply.
    (i) Example 1--(A) Facts. AB Partnership is a calendar-year 
partnership for Federal income tax purposes whose partners are A and B, 
each of whom is an individual and has a 50 percent interest in income, 
gain, loss, and deduction. Several years ago, B contributed property to 
AB Partnership subject to a Sec.  1.752-1 liability. At the beginning 
of AB Partnership's 2024 taxable year (the beginning of the day on 
January 1, 2024), A's adjusted basis in its interest in AB Partnership 
is $19X, and B's adjusted basis in its interest in AB Partnership is 
$17X. At 10:01 a.m. on August 29, 2024, AB Partnership makes a 
qualified conservation contribution. On August 29, 2024, the amount of 
the Sec.  1.752-1 liability is $10X and is allocated under the rules of 
section 752 to A. During 2024, there were no variations in any 
partner's interests in AB Partnership within the meaning of section 
706. During 2024, AB Partnership earned $8X of ordinary income and 
sustained ($4X) of capital loss in the ordinary course of its business, 
both of which are allocated equally to A and B. Within 2024, AB 
Partnership earned $6X of ordinary income, and sustained ($4X) of 
capital loss between the beginning of the day on January 1, 2024, and 
10:00 a.m. on August 29, 2024, and AB Partnership earned $2X of 
ordinary income, and sustained $0X of capital loss between 10:01 a.m. 
on August 29, 2024, and the end of the day on December 31, 2024. Other 
than the qualified conservation contribution, none of AB Partnership's 
items are extraordinary items within the meaning of Sec.  1.706-
4(e)(2). In April 2024, AB Partnership distributed $1X cash to A. In 
November 2024, B contributed $2X cash to AB Partnership.
    (B) Analysis. The ultimate members of AB Partnership are A and B 
because they each receive a distributive share of the qualified 
conservation contribution and are not partnerships or S corporations. 
To determine A's and B's modified bases, AB Partnership must start with 
A's and B's adjusted bases in AB Partnership as of the beginning of the 
first day of the taxable year of AB Partnership and then make the

[[Page 54316]]

adjustments required under paragraphs (l)(2)(ii) through (vi) of this 
section. Accordingly, the computation of A's beginning modified basis 
begins with $19X, and the computation of B's modified basis begins with 
$17X. First, those amounts must be increased by any contributions 
between the beginning of the day on January 1, 2024, and 10 a.m. on 
August 29, 2024. Because there were none, after this step, the 
computation of A's modified basis remains at $19X and the computation 
of B's modified basis remains at $17X. Next, these amounts must be 
adjusted for any additional acquisitions of partnership interests by an 
existing partner or partial dispositions of partnership interests by a 
continuing partner between the beginning of the partnership's taxable 
year and the time of day at which the qualified conservation 
contribution is made. Because there were none, after this step, the 
computation of A's modified basis remains at $19X and the computation 
of B's modified basis remains at $17X. Then these amounts must be 
adjusted as provided in section 705 by A's and B's hypothetical 
distributive shares of AB Partnership's items attributable to the 
portion of the year between the beginning of the day on January 1, 
2024, and 10:00 a.m. on August 29, 2024. Thus, the computations of A's 
and B's modified bases will each reflect an increase for their 
hypothetical $3X distributive share of the $6X ordinary income that AB 
Partnership earned between the beginning of the day on January 1, 2024, 
and 10:00 a.m. on August 29, 2024, and a decrease for their 
hypothetical ($2X) distributive share of the ($4X) capital loss that AB 
Partnership incurred between the beginning of the day on January 1, 
2024, and 10:00 a.m. on August 29, 2024. Therefore, after this step, 
the computation of A's modified basis reflects an increase from $19X to 
$20X, and the computation of B's modified basis reflects an increase 
from $17X to $18X. Next, these amounts must be reduced by any 
distributions between the beginning of the day on January 1, 2024, and 
10:00 a.m. on August 29, 2024. Thus, the computation of A's modified 
basis reflects a reduction from $20X to $19X. B did not receive any 
distribution, so the computation of B's modified basis remains at $18X. 
Finally, the full amount of A's and B's shares of Sec.  1.752-1 
liabilities must be subtracted. Thus, the computation of A's modified 
basis reflects a reduction from $19X to $9X, which is A's modified 
basis. B's modified basis is $18X.
    (ii) Example 2--(A) Facts. CD Partnership, a partnership for 
Federal income tax purposes, is a calendar-year partnership using the 
calendar day convention under Sec.  1.706-4 whose partners on January 
1, 2024, are C and D, each of whom is an individual and has a 50 
percent interest in income, gain, loss, and deduction. On March 15, 
2024, C sells its interest to E, a C corporation. At 1:15 p.m. on 
September 15, 2024, CD Partnership makes a qualified conservation 
contribution. On September 21, 2024, D sells its interest to F, an 
individual. During 2024, CD Partnership earned $8X of ordinary income 
and sustained ($14X) of ordinary loss. Within 2024, CD Partnership 
earned all $8X of ordinary income in November and December, and 
sustained all ($14X) of ordinary loss in April through August. In May 
2024, D contributed $6X cash to CD Partnership, and E contributed 
property with a fair market value of $6X and basis of $3X. D and E are 
equal partners during the period in which they are both partners. CD 
Partnership made no distributions during 2024. CD Partnership had no 
Sec.  1.752-1 liabilities during 2024. In accordance with Sec.  1.706-
4(e)(2)(xiii), CD Partnership treats its qualified conservation 
contribution as an extraordinary item allocable only to D and E, its 
partners at 1:15 p.m. on September 15, 2024. Other than the qualified 
conservation contribution, none of AB Partnership's items are 
extraordinary items within the meaning of Sec.  1.706-4(e)(2). CD 
Partnership uses the proration method under Sec.  1.706-4 to allocate 
its items among C, D, E, and F. Under the proration method, CD 
Partnership allocates each C, D, E, and F a distributive share of a 
portion of both the $8X ordinary income and the ($14X) ordinary loss. 
D's adjusted basis in its interest in CD Partnership at the beginning 
of CD Partnership's 2024 taxable year (the beginning of the day on 
January 1, 2024) is $8X. E's adjusted basis in its interest in CD 
Partnership immediately after E acquires C's interest in CD Partnership 
is $6X.
    (B) Analysis. The ultimate members of CD Partnership are D and E 
because they each receive a distributive share of the qualified 
conservation contribution and are not partnerships or S corporations. 
To determine D's and E's modified bases, CD Partnership must start with 
D's and E's adjusted bases in CD Partnership as of the beginning of the 
day on January 1, 2024, and then make the adjustments required under 
paragraphs (l)(2)(ii) through (vi) of this section. However, because E 
was not a partner as of the beginning of the day on January 1, 2024, CD 
Partnership must start with E's adjusted basis immediately after E's 
purchase of C's interest in CD Partnership. Accordingly, the 
computation of D's modified basis begins with $8X, and the computation 
of E's modified basis begins with $6X. Then, these amounts must be 
increased by any contributions made by D or E, respectively, to CD 
Partnership between the beginning of the day on January 1, 2024, and 
1:14 p.m. on September 15, 2024. Therefore, the computation of D's 
modified basis reflects an increase from $8X to $14X (for D's $6X 
contribution of cash to CD Partnership in May 2024), and the 
computation of E's modified basis reflects an increase from $6X to $9X 
(for E's contribution of property to CD Partnership with a basis of $3X 
in May 2024). Next, these amounts must be adjusted for any additional 
acquisitions of partnership interests by an existing partner or partial 
dispositions of partnership interests by a continuing partner between 
the beginning of the partnership's taxable year and the time of day at 
which the qualified conservation contribution is made. Because there 
were none, after this step, the computation of D's modified basis 
remains at $14X and the computation of E's modified basis remains at 
$9X. Next, these amounts must be adjusted as provided in section 705 by 
D's and E's hypothetical distributive shares of CD Partnership's items 
attributable to the portion of the year between the beginning of the 
day on January 1, 2024, and 1:14 p.m. on September 15, 2024. CD 
Partnership must perform the analysis using an interim closing method 
to a hypothetical variation at 1:14 p.m. on September 15, 2024, 
immediately prior to the qualified conservation contribution. The 
computation of D's modified basis will reflect an adjustment for its 
hypothetical distributive share of all CD Partnership's items incurred 
from the beginning of the day on January 1, 2024, through 1:14 p.m. on 
September 15, 2024. The computation of E's modified basis will reflect 
an adjustment for its hypothetical distributive share of all CD 
Partnership's items incurred from the end of the day on March 15, 2024, 
through 1:14 p.m. on September 15, 2024. For purposes of this paragraph 
(l)(4)(ii)(B) (Example 2), it does not matter that CD Partnership 
actually used the proration method to allocate its 2024 income. 
Instead, under this hypothetical calculation of the distributive 
shares, the computation of D's and E's modified bases will each reflect 
a reduction for their 50 percent share of the ($14X) ordinary loss. 
Because none of CD Partnership's $8X of ordinary income was earned 
between

[[Page 54317]]

the beginning of the day on January 1, 2024, and 1:14 p.m. on September 
15, 2024, neither D's nor E's modified basis will reflect an increase 
for any amount of that income. Thus, after this step, the computation 
of D's modified basis reflects a reduction from $14X to $7X, and the 
computation of E's modified basis reflects a reduction from $9X to $2X. 
Then, these amounts must be reduced by any distributions between the 
beginning of the day on January 1, 2024, and 1:14 p.m. on September 15, 
2024. Because there were none, after this step, the computation of D's 
modified basis remains at $7X, and the computation of E's modified 
basis remains at $2X. Finally, the full amount of D's and E's shares of 
Sec.  1.752-1 liabilities must be subtracted. Because there were none, 
D's modified basis is $7X, and E's modified basis is $2X.
    (iii) Example 3--(A) Facts. HI Inc. is a calendar-year S 
corporation whose shareholders on January 1, 2024, are H and I, each of 
whom owns 50 percent of the shares. On May 1, 2024, H sells all of its 
stock to J. In June 2024, HI Inc. contributes a conservation easement 
that is a qualified conservation contribution on 400 acres of real 
property. HI Inc.'s adjusted basis in the conservation easement is $12X 
(which is different from HI Inc.'s adjusted basis in the 400 acres and 
also may be different from the value of the conservation easement). On 
July 1, 2024, I sells all of its stock to K. Under Sec.  1.1377-1, HI 
Inc. allocates its qualified conservation contribution \1/6\ to H, \1/
4\ to I, \1/3\ to J, and \1/4\ to K. Pursuant to the second sentence of 
section 1367(a)(2)(B), as a result of the qualified conservation 
contribution, H's adjusted basis in its shares is reduced by $2X, I's 
adjusted basis in its shares is reduced by $3X, J's adjusted basis in 
its shares is reduced by $4X, and K's adjusted basis in its shares is 
reduced by $3X. At the end of HI Inc.'s 2024 taxable year (the end of 
the day on December 31, 2024), J's adjusted basis in its shares is $15X 
and K's adjusted basis in its shares is $11X. Immediately prior to H's 
sale to J, H's adjusted basis in its shares was $8X. Immediately prior 
to I's sale to K, I's adjusted basis in its shares was $7X. Whether H, 
I, J, or K have adjusted basis in indebtedness of HI Inc., has no 
effect on the computation of their modified bases. H is an estate of a 
deceased shareholder, and I, J, and K are individuals that are not 
nonresident aliens.
    (B) Analysis. The ultimate members of HI Inc. are H, I, J, and K, 
because they each receive a pro rata share of the qualified 
conservation contribution and are not partnerships or S corporations. 
To determine H's, I's, J's, and K's modified bases, HI Inc. must begin 
with each shareholder's adjusted basis in its shares as of the end of 
the day on December 31, 2024 (the end of the S corporation's taxable 
year in which it made the qualified conservation contribution). 
However, because H and I were not shareholders as of the end of the day 
on December 31, 2024, HI Inc. must begin with H's adjusted basis 
immediately before H's sale to J, and I's adjusted basis immediately 
before I's sale to K. Accordingly, the computation of H's modified 
basis begins with $8X, the computation of I's modified basis begins 
with $7X, the computation of J's modified basis begins with $15X, and 
the computation of K's modified basis begins with $11X. Next, HI Inc. 
must increase these amounts by the extent the adjusted bases were 
reduced as a result of the qualified conservation contribution. 
Accordingly, the computation of H's modified basis reflects an increase 
from $8X to $10X, the computation of I's modified basis reflects an 
increase from $7X to $10X, the computation of J's modified basis 
reflects an increase from $15X to $19X, and the computation of K's 
modified basis reflects an increase from $11X to $14X. Finally, HI Inc. 
must multiply each of these amounts by the number of days during 2024 
in which each ultimate member was a shareholder, and divide by 366 (the 
total number of days in HI Inc.'s 2024 taxable year). H was a 
shareholder for 122 days. Thus, H's modified basis is $3.33X ($10X x 
122/366). I was a shareholder for 183 days. Thus, I's modified basis is 
$5X ($10X x 183/366). J was a shareholder for 244 days. Thus, J's 
modified basis is $12.67X ($19X x 244/366). K was a shareholder for 183 
days. Thus, K's modified basis is $7X ($14X x 183/366).
    (iv) Example 4--(A) Facts. PQ Partnership is a calendar-year 
partnership for Federal income tax purposes whose partners are 
individuals P and Q. At the beginning of PQ Partnership's 2024 taxable 
year (the beginning of the day on January 1, 2024), P has a sixty 
percent interest in all of PQ Partnership's items, including items of 
income, gain, loss, deduction, credit, and charitable contributions, 
and P's adjusted basis in its interest in PQ Partnership is $60X. At 
the beginning of PQ Partnership's 2024 taxable year, Q has a forty 
percent interest in all of PQ Partnership's items, including items of 
income, gain, loss, deduction, credit, and charitable contributions, 
and Q's adjusted basis in its interest in PQ Partnership is $30X. On 
March 15, 2024, P sells two-thirds of P's interest in PQ Partnership to 
individual Z, who was not previously a partner in PQ Partnership, for 
$55X. At the time of the sale, P's adjusted basis in the partnership 
interests P sold to Z was $40X. At noon on August 29, 2024, PQ 
Partnership makes a qualified conservation contribution. PQ Partnership 
allocates twenty percent of the qualified conservation contribution to 
P, forty percent to Q, and forty percent to Z. Between January 1 and 
August 29, 2024, PQ Partnership had no items of income, gain, loss, or 
deduction, and did not make any distributions. No partner made any 
contributions during 2024. PQ Partnership did not have any Sec.  1.752-
1 liabilities during 2024.
    (B) Analysis. P, Q, and Z are the ultimate members of PQ 
Partnership because they each receive a distributive share of the 
qualified conservation contribution and are not partnerships or S 
corporations. To determine P's, Q's, and Z's modified bases, PQ 
Partnership must start with P's, Q's, and Z's adjusted bases in PQ 
Partnership as of the beginning of the first day of the taxable year of 
PQ Partnership and then make the adjustments required under paragraphs 
(l)(2)(ii) through (vi) of this section. However, because Z was not a 
partner as of the beginning of the day on January 1, 2024, PQ 
Partnership must start with Z's adjusted basis immediately after Z's 
purchase of two-thirds of P's interest in PQ Partnership. Accordingly, 
the computation of P's modified basis begins with $60X, the computation 
of Q's modified basis begins with $30X, and the computation of Z's 
modified basis begins with $55X. First, those amounts must be increased 
by any contributions between the beginning of the day on January 1, 
2024, and noon on August 29, 2024. Because there were none, after this 
step, the computation of P's modified basis remains at $60X, the 
computation of Q's modified basis remains at $30X, and the computation 
of Z's modified basis remains at $55X. Next, these amounts must be 
adjusted for any additional acquisitions of partnership interests by an 
existing partner or partial dispositions of partnership interests by a 
continuing partner between the beginning of the partnership's taxable 
year and the time of day at which the qualified conservation 
contribution is made. P sold two-thirds of its interest to Z prior to 
PQ Partnership's qualified conservation contribution; P's basis in the 
interests it sold was $40X. As a result, the computation of P's 
modified basis reflects a reduction from $60X to $20X. Then these 
amounts must be

[[Page 54318]]

adjusted as provided in section 705 by P's, Q's, and Z's hypothetical 
distributive shares of PQ Partnership's items attributable to the 
portion of the year between the beginning of the day on January 1, 
2024, and noon on August 29, 2024. Because there were none, after this 
step, the computation of P's modified basis remains at $20X, the 
computation of Q's modified basis remains at $30X, and the computation 
of Z's modified basis remains at $55X. Next, these amounts must be 
reduced by any distributions between the beginning of the day on 
January 1, 2024, and noon on August 29, 2024. Because there were none, 
after this step, the computation of P's modified basis remains at $20X, 
the computation of Q's modified basis remains at $30X, and the 
computation of Z's modified basis remains at $55X. Finally, the full 
amount of P's, Q's, and Z's shares of Sec.  1.752-1 liabilities must be 
subtracted. Because there were none, P's modified basis is $20X, Q's 
modified basis is $30X, and Z's modified basis is $55X.
    (m) Allocation of modified basis--(1) In general. An allocation of 
an ultimate member's modified basis to the portion of the real property 
with respect to which the qualified conservation contribution is made 
must be made in accordance with this paragraph (m). Rules for 
allocating an ultimate member's modified basis in a contributing 
partnership are provided in paragraph (m)(2) of this section. Rules for 
allocating an ultimate member's modified basis in a contributing S 
corporation are provided in paragraph (m)(3) of this section. Rules for 
allocating an ultimate member's modified basis in an upper-tier 
partnership are provided in paragraph (m)(4) of this section. Rules for 
allocating an ultimate member's modified basis in an upper-tier S 
corporation are provided in paragraph (m)(5) of this section. Records 
must be kept in accordance with paragraph (m)(6) of this section.
    (2) Determination of relevant basis for an ultimate member holding 
a direct interest in a contributing partnership--(i) Narrative rule. 
This paragraph (m)(2) applies in the case of an ultimate member holding 
a direct interest in a contributing partnership and provides that a 
contributing partnership must determine each such ultimate member's 
relevant basis as provided in this paragraph (m)(2). Relevant basis 
equals each ultimate member's modified basis as determined under 
paragraph (l)(2) of this section multiplied by a fraction--
    (A) The numerator of which is the ultimate member's share of the 
contributing partnership's adjusted basis in the portion of the real 
property with respect to which the qualified conservation contribution 
is made as determined under paragraph (m)(2)(ii) of this section; and
    (B) The denominator of which is the ultimate member's portion of 
the adjusted basis in all the contributing partnership's properties as 
determined under paragraph (m)(2)(iii) of this section.
    (ii) Ultimate member's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made. For purposes of 
this paragraph (m)(2), an ultimate member's share of the contributing 
partnership's adjusted basis in the portion of the real property with 
respect to which the qualified conservation contribution is made equals 
the contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made (determined as of the time of day of the 
contribution) multiplied by a fraction--
    (A) The numerator of which is the ultimate member's distributive 
share of the qualified conservation contribution; and
    (B) The denominator of which is the total amount of the 
contributing partnership's qualified conservation contribution.
    (iii) Ultimate member's portion of the adjusted basis in all the 
contributing partnership's properties--(A) For purposes of this 
paragraph (m)(2), an ultimate member's portion of the adjusted basis in 
all the contributing partnership's properties is equal to the sum of:
    (1) The ultimate member's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made as determined 
under paragraph (m)(2)(ii) of this section; plus
    (2) The ultimate member's portion of the adjusted basis in all the 
contributing partnership's properties other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made as determined under paragraph (m)(2)(iii)(B) of 
this section.
    (B) To determine a partner's portion of the adjusted basis in all 
of a contributing partnership's properties, the contributing 
partnership must apportion among its partners its adjusted basis in 
each of its properties (except the portion of the real property with 
respect to which the qualified conservation contribution is made), 
using the adjusted basis immediately before the qualified conservation 
contribution, without duplication or omission of any property, and by 
treating the adjusted basis in each property as not less than zero. 
This apportionment must be done under principles similar to the 
determination of the partners' interests in the partnership under 
section 704(b), including the factors in Sec.  1.704-1(b)(3)(ii). In 
addition, the apportionment must reflect section 704(c) principles. For 
example, if a partnership property has built-in loss (the adjusted 
basis of the property exceeds its fair market value), and section 
704(c) would require all of that built-in loss to be allocated to a 
certain partner if that property was sold, all of the basis in the 
property that exceeds the property's fair market value must be 
apportioned to the partner to whom the loss would be allocated if the 
property was sold.
    (iv) Formulaic rule. The rule of this paragraph (m)(2) is also 
expressed in the following formula:

Equation 1 to Paragraph (m)(2)(iv)

R = M x (T / (D + T))

Where:

R = Relevant basis.
M = Modified basis as determined under paragraph (l) of this 
section.
D = Ultimate member's portion of the adjusted basis in all the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made) as determined under paragraph (m)(2)(iii)(B) 
of this section.
T = Ultimate member's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made, determined 
according to the following formula: A x (B / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
B = Ultimate member's distributive share of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    (3) Determination of relevant basis for an ultimate member holding 
a direct interest in a contributing S corporation--(i) Narrative rule. 
This paragraph (m)(3) applies in the case of an ultimate member holding 
a direct interest in a contributing S corporation and provides that a 
contributing S corporation must determine each such ultimate member's 
relevant basis as provided in this paragraph (m)(3). Relevant basis 
equals each ultimate

[[Page 54319]]

member's modified basis as determined under paragraph (l)(3) of this 
section multiplied by a fraction--
    (A) The numerator of which is the ultimate member's pro rata 
portion of the contributing S corporation's adjusted basis in the 
portion of the real property with respect to which the qualified 
conservation contribution is made; and
    (B) The denominator of which is the ultimate member's pro rata 
portion of the adjusted basis in all the contributing S corporation's 
properties (including the portion of the real property with respect to 
which the qualified conservation contribution is made).
    (ii) Formulaic rule. The rule of this paragraph (m)(3) is also 
expressed in the following formula:

Equation 2 to Paragraph (m)(3)(ii)

R = M x (E / F)

Where:

R = Relevant basis.
M = Modified basis as determined under paragraph (l) of this 
section.
E = Ultimate member's pro rata portion of the contributing S 
corporation's adjusted basis in the portion of the real property 
with respect to which the qualified conservation contribution is 
made.
F = Ultimate member's pro rata portion of the adjusted basis in all 
the contributing S corporation's properties (including the portion 
of the real property with respect to which the qualified 
conservation contribution is made).

    (4) Determination of relevant basis for an ultimate member holding 
a direct interest in an upper-tier partnership--(i) In general. This 
paragraph (m)(4) applies in the case of an ultimate member holding a 
direct interest in an upper-tier partnership. Each such ultimate 
member's modified basis must be traced through all upper-tier 
partnerships to the contributing partnership, and the contributing 
partnership must determine the relevant basis. This involves a multi-
step process under which, beginning with the upper-tier partnership in 
which the ultimate member holds a direct interest, each upper-tier 
partnership must perform calculations, and then finally the 
contributing partnership must use those calculations to compute the 
ultimate member's relevant basis. For simplicity, this paragraph (m)(4) 
describes a situation in which there are two tiers of partnerships--a 
contributing partnership and an upper-tier partnership. In a situation 
involving more tiers, each partnership must apply the rules and 
principles of this paragraph (m)(4) iteratively to determine relevant 
basis.
    (ii) Upper-tier partnership--(A) Narrative rule--(1) In general. 
The upper-tier partnership must determine the portion of each ultimate 
member's modified basis that is allocable to the upper-tier 
partnership's interest in the partnership in which it holds a direct 
interest (in a situation involving only two tiers of partnerships, that 
will be the contributing partnership). This determination must be done 
in accordance with the principles of paragraph (m)(2) of this section, 
the rule in paragraph (m)(4)(ii)(A)(2) of this section, and the formula 
provided in paragraph (m)(4)(ii)(B) of this section. In other words, 
the formula provided in paragraph (m)(4)(ii)(B) of this section is 
similar to the formula provided in paragraph (m)(2)(iv) of this 
section, except that, instead of determining the portion of modified 
basis that is allocable to the portion of the real property with 
respect to which the qualified conservation contribution is made, the 
formula in paragraph (m)(4)(ii)(B) of this section determines the 
portion of modified basis that is allocable to the upper-tier 
partnership's interest in the next lower-tier partnership. As explained 
in paragraph (m)(4)(iii) of this section, the contributing partnership 
will then use the amount determined under the formula in paragraph 
(m)(4)(ii)(B) of this section to compute the portion of modified basis 
that is allocable to the portion of the real property with respect to 
which the qualified conservation contribution is made.
    (2) Apportionment of upper-tier partnership's adjusted bases in its 
properties. To determine a partner's portion of the adjusted basis in 
all of an upper-tier partnership's properties, the upper-tier 
partnership must apportion among its partners its adjusted basis in 
each of its properties (except its interest in the lower-tier 
partnership), using the adjusted basis immediately before the qualified 
conservation contribution, without duplication or omission of any 
property, and by treating the adjusted basis in each property as not 
less than zero. This apportionment must be done under principles 
similar to the determination of the partners' interests in the 
partnership under section 704(b), including the factors in Sec.  1.704-
1(b)(3)(ii). In addition, the apportionment must reflect section 704(c) 
principles. For example, if a partnership property has built-in loss 
(the adjusted basis of the property exceeds its fair market value), and 
section 704(c) would require all of that built-in loss to be allocated 
to a certain partner if that property was sold, all of the basis in the 
property that exceeds the property's fair market value must be 
apportioned to the partner to whom the loss would be allocated if the 
property was sold.
    (B) Formulaic rule. The rule of this paragraph (m)(4)(ii) is also 
expressed in the following formula:

Equation 3 to Paragraph (m)(4)(ii)(B)

G = M x (U / (J + U))

Where:

G = The portion of the ultimate member's modified basis that is 
allocable to the upper-tier partnership's interest in the 
contributing partnership.
M = Modified basis as determined under paragraph (l) of this 
section.
J = Ultimate member's portion of the adjusted basis in all the 
upper-tier partnership's properties (other than the upper-tier 
partnership's interest in the contributing partnership) as 
determined under paragraph (m)(4)(ii)(A)(2) of this section.
U = Ultimate member's share of the upper-tier partnership's adjusted 
basis in its interest in the contributing partnership, determined 
according to the following formula: H x (B / K).
H = Upper-tier partnership's adjusted basis in its interest in the 
contributing partnership.
B = Ultimate member's distributive share of the qualified 
conservation contribution.
K = Upper-tier partnership's allocated portion of the qualified 
conservation contribution.

    (iii) Contributing partnership--(A) Narrative rule. After 
completion of the computations under paragraph (m)(4)(ii) of this 
section, the contributing partnership must determine the portion of the 
amount determined under item G (see paragraph (m)(4)(ii)(B) of this 
section) with respect to each ultimate member that is allocable to the 
portion of the real property with respect to which the qualified 
conservation contribution is made. This determination must be done in 
accordance with the principles of paragraph (m)(2) of this section and 
the formula provided in paragraph (m)(4)(iii)(B) of this section.
    (B) Formulaic rule. The rule of this paragraph (m)(4)(iii) is also 
expressed in the following formula:

Equation 4 to Paragraph (m)(4)(iii)(B)

R = G x (V / (L + V))

Where:

R = Relevant basis.
G = Amount determined with respect to item G as described under 
paragraph (m)(4)(ii)(B) of this section.
L = Upper-tier partnership's portion of adjusted basis in all the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made) as determined under paragraph (m)(2)(iii)(B) 
of this section.
V = Upper-tier partnership's share of the contributing partnership's 
adjusted basis

[[Page 54320]]

in the portion of the real property with respect to which the 
qualified conservation contribution is made, determined according to 
the following formula: A x (K / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
K = Upper-tier partnership's allocated portion of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    (5) Determination of relevant basis for an ultimate member holding 
a direct interest in an upper-tier S corporation--(i) In general. This 
paragraph (m)(5) applies in the case of an ultimate member holding a 
direct interest in an upper-tier S corporation. Each such ultimate 
member's modified basis must be traced through the upper-tier S 
corporation and any upper-tier partnerships to the contributing 
partnership, and the contributing partnership must determine the 
relevant basis. This involves a multi-step process under which, 
beginning with the upper-tier S corporation, the upper-tier S 
corporation and any upper-tier partnerships must perform calculations, 
and then finally the contributing partnership must use those 
calculations to compute the ultimate member's relevant basis. For 
simplicity, this paragraph (m)(5) describes a situation in which there 
are two tiers--a contributing partnership and an upper-tier S 
corporation. In a situation involving more tiers, each partnership and 
the upper-tier S corporation must apply the rules and principles of 
this paragraph (m) iteratively to determine relevant basis.
    (ii) Upper-tier S corporation--(A) Narrative rule. The upper-tier S 
corporation must determine the portion of each ultimate member's 
modified basis that is allocable to the upper-tier S corporation's 
interest in the partnership in which it holds a direct interest (in a 
situation involving only two tiers, that will be the contributing 
partnership). This determination must be done in accordance with the 
principles of paragraph (m)(3) of this section and the formula provided 
in paragraph (m)(5)(ii)(B) of this section. In other words, the formula 
provided in paragraph (m)(5)(ii)(B) of this section is similar to the 
formula provided in paragraph (m)(3)(ii) of this section, except that, 
instead of determining the portion of modified basis that is allocable 
to the portion of the real property with respect to which the qualified 
conservation contribution is made, the formula in paragraph 
(m)(5)(ii)(B) of this section determines the portion of modified basis 
that is allocable to the upper-tier S corporation's interest in the 
next lower-tier partnership. As explained in paragraph (m)(5)(iii) of 
this section, the contributing partnership will then use the amount 
determined under the formula in paragraph (m)(5)(ii)(B) of this section 
to compute the portion of modified basis that is allocable to the 
portion of the real property with respect to which the qualified 
conservation contribution is made.
    (B) Formulaic rule. The rule of this paragraph (m)(5)(ii) is also 
expressed in the following formula:

Equation 5 to Paragraph (m)(5)(ii)(B)

N = M x (P / Q)

Where:

N = Portion of the ultimate member's modified basis that is 
allocable to the upper-tier S corporation's interest in the 
contributing partnership.
M = Modified basis as determined under paragraph (l) of this 
section.
P = Ultimate member's pro rata portion of the upper-tier S 
corporation's adjusted basis in its interest in the contributing 
partnership.
Q = Ultimate member's pro rata portion of the adjusted basis in all 
the upper-tier S corporation's properties (including the upper-tier 
S corporation's interest in the contributing partnership).

    (iii) Contributing partnership--(A) Narrative rule. After 
completion of the computations under paragraph (m)(5)(ii) of this 
section, the contributing partnership must determine the portion of the 
amount determined under item N (see paragraph (m)(5)(ii)(B) of this 
section) with respect to each ultimate member that is allocable to the 
portion of the real property with respect to which the qualified 
conservation contribution is made. This determination must be done in 
accordance with the principles of paragraph (m)(2) of this section and 
the formula provided in paragraph (m)(5)(iii)(B) of this section.
    (B) Formulaic rule. The rule of this paragraph (m)(5)(iii) is also 
expressed in the following formula:

Equation 6 to Paragraph (m)(5)(iii)(B)

R = N x (W / (S + W))

Where:

R = Relevant basis.
N = Amount determined with respect to item N as described under 
paragraph (m)(5)(ii)(B) of this section.
S = Upper-tier S corporation's portion of the adjusted basis in all 
the contributing partnership's properties (other than the portion of 
the real property with respect to which the qualified conservation 
contribution is made) as determined under paragraph (m)(2)(iii)(B) 
of this section.
W = Upper-tier S corporation's share of the contributing 
partnership's adjusted basis in the portion of the real property 
with respect to which the qualified conservation contribution is 
made, determined according to the following formula: A x (Y / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
Y = Upper-tier S corporation's allocated portion of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    (6) Recordkeeping requirements. Contributing partnerships, 
contributing S corporations, upper-tier partnerships, and upper-tier S 
corporations must maintain dated, written statements in their books and 
records, by the due date, including extensions, of their Federal income 
tax returns, substantiating the computation of each ultimate member's 
adjusted basis, modified basis, and relevant basis. See Sec.  1.6001-1. 
These statements need not be maintained (nor does modified basis or 
relevant basis need to be computed) with respect to contributions that 
meet an exception in paragraph (n)(2) or (3) of this section, unless 
the contribution also meets the exception in paragraph (n)(4) of this 
section (in which case these statements need to be maintained and 
modified basis and relevant basis need to be computed).
    (7) Examples. The following examples illustrate the provisions of 
this paragraph (m). For the examples in this paragraph (m)(7), assume 
that the partnership allocations comply with the rules of subchapter K 
of chapter 1 of the Code and the exceptions in paragraph (n) of this 
section do not apply.
    (i) Example 1--(A) Facts. YZ Partnership is a partnership for 
Federal income tax purposes whose partners are individuals Y and Z. YZ 
Partnership owns 100 acres of real property with an adjusted basis of 
$10X. YZ Partnership makes a qualified conservation contribution on 60 
acres of the property. YZ Partnership claims a contribution of $18X, 
which it allocates $12X to Y and $6X to Z. YZ Partnership's adjusted 
basis in the 60 acres is $6X, and its adjusted basis in all of its 
other properties (including its $4X basis in the 40 acres on which a 
qualified conservation contribution was not made) is $18X. Y's modified 
basis is $8X. Y's portion of YZ Partnership's adjusted basis in all 
partnership property (other than the 60 acres) as determined under 
paragraph (m)(2)(iii)(B) of this section is $4X. Z's modified basis is 
$12X. Z's portion of

[[Page 54321]]

YZ Partnership's adjusted basis in all partnership property (other than 
the 60 acres) as determined under paragraph (m)(2)(iii)(B) of this 
section is $14X.
    (B) General analysis. Y and Z are the ultimate members of YZ 
Partnership because they each receive a distributive share of the 
qualified conservation contribution and are not partnerships or S 
corporations. Their relevant bases must be determined according to the 
following formula:

Equation 7 to Paragraph (m)(7)(i)(B)

R = M x (T / (D + T))

Where:

R = Relevant basis.
M = Modified basis as determined under paragraph (l) of this 
section.
D = Ultimate member's portion of the adjusted basis in all of the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made) as determined under paragraph (m)(2)(iii)(B) 
of this section.
T = Ultimate member's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made, determined 
according to the following formula: A x (B / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
B = Ultimate member's distributive share of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    (C) Y's relevant basis. With respect to Y:
    (1) M = $8X.
    (2) D = $4X.
    (3) A = $6X.
    (4) B = $12X.
    (5) C = $18X.
    (6) Thus, T is $4X = $6X x ($12X / $18X).
    (7) Accordingly, Y's relevant basis is $4X = $8X x ($4X / ($4X + 
$4X)).
    (D) Z's relevant basis. With respect to Z:
    (1) M = $12X.
    (2) D = $14X.
    (3) A = $6X.
    (4) B = $6X.
    (5) C = $18X.
    (6) Thus, T is $2X = $6X x ($6X / $18X).
    (7) Accordingly, Z's relevant basis is $1.5X = $12X x ($2X / ($14X 
+ $2X)).
    (E) Sum of the relevant bases. The amount of YZ Partnership's 
claimed contribution is $18X, which exceeds 2.5 times the sum of Y's 
and Z's relevant bases, which is $13.75X ($13.75X = 2.5 x (Y's relevant 
basis of $4X + Z's relevant basis of $1.5X)). Accordingly, YZ 
Partnership's contribution is a disallowed qualified conservation 
contribution. No person may claim any deduction with respect to this 
contribution.
    (ii) Example 2--(A) Facts. CD Inc. is an S corporation with 
shareholders C and D, each of whom is an individual that is not a 
nonresident alien. C owns one third of the outstanding stock in CD 
Inc., and D owns the remaining two thirds. CD Inc. owns 100 acres of 
real property with an adjusted basis of $10X. CD Inc. makes a qualified 
conservation contribution on 60 acres of the property. CD Inc. claims a 
contribution of $9X, which it allocates $3X to C and $6X to D. CD 
Inc.'s adjusted basis in the 60 acres is $6X, and its adjusted basis in 
all its properties (including its $6X basis in the 60 acres) is $24X. 
C's modified basis in CD Inc. is $8X. D's modified basis in CD Inc. is 
$12X.
    (B) General analysis. C and D are the ultimate members of CD Inc. 
because they each receive a pro rata share of the qualified 
conservation contribution and are not partnerships or S corporations. 
Their relevant bases must be determined according to the following 
formula:

Equation 8 to Paragraph (m)(7)(ii)(B)

R = M x (E / F)

Where:

R = Relevant basis.
M = Modified basis as determined under paragraph (l) of this 
section.
E = Ultimate member's pro rata portion of the contributing S 
corporation's adjusted basis in the portion of the real property 
with respect to which the qualified conservation contribution is 
made.
F = Ultimate member's pro rata portion of the adjusted basis in all 
the contributing S corporation's properties (including the portion 
of the real property with respect to which the qualified 
conservation contribution is made).

    (C) C's relevant basis. With respect to C:
    (1) M = $8X.
    (2) E = $2X (\1/3\ of $6X).
    (3) F = $8X (\1/3\ of $24X).
    (4) Thus, C's relevant basis is $2X = $8X x ($2X / $8X).
    (D) D's relevant basis. With respect to D:
    (1) M = $12X.
    (2) E = $4X (\2/3\ of $6X).
    (3) F = $16X (\2/3\ of $24X).
    (4) Thus, D's relevant basis is $3X = $12X x ($4X / $16X).
    (E) Sum of the relevant bases. The amount of CD Inc.'s claimed 
qualified conservation contribution is $9X, which does not exceed 2.5 
times the sum of C's and D's relevant bases, which is $12.50 ($12.50X = 
2.5 x (C's relevant basis of $2X + D's relevant basis of $3X)). 
Accordingly, CD Inc.'s contribution is not a disallowed qualified 
conservation contribution (that is, is not disallowed by section 
170(h)(7) and paragraph (j) of this section).
    (iii) Example 3--(A) Facts. LTP Partnership is a partnership for 
Federal income tax purposes whose partners are individual E and UTP 
Partnership, a partnership for Federal income tax purposes. UTP 
Partnership's partners are C corporations P and Q. LTP Partnership owns 
300 acres of real property. LTP Partnership makes a qualified 
conservation contribution on all 300 acres. LTP Partnership claims a 
qualified conservation contribution of $22X, which it allocates $2X to 
E and $20X to UTP Partnership. UTP Partnership allocates its $20X share 
of the qualified conservation contribution $6X to P and $14X to Q. LTP 
Partnership's basis in the 300 acres is $18X, and its adjusted basis in 
all of its other properties is $12X. E's modified basis in LTP 
Partnership is $4X. E's portion of LTP Partnership's adjusted basis in 
all partnership property (other than the 300 acres) as determined under 
paragraph (m)(2)(iii)(B) of this section is $4.36X. UTP Partnership's 
portion of LTP Partnership's adjusted basis in all partnership property 
(other than the 300 acres) as determined under paragraph (m)(2)(iii)(B) 
of this section is $7.64X. UTP Partnership's adjusted basis in its 
interest in LTP Partnership is $19, and its adjusted basis in all other 
properties is $6X. P's modified basis in UTP Partnership is $12X. P's 
portion of UTP Partnership's adjusted basis in all partnership property 
(other than the interest in LTP Partnership) as determined under 
paragraph (m)(4)(ii)(A)(2) of this section is $3.6X. Q's modified basis 
in UTP Partnership is $8X. Q's portion of UTP Partnership's adjusted 
basis of all partnership property (other than the interest in LTP 
Partnership) as determined under paragraph (m)(4)(ii)(A)(2) of this 
section is $2.4X.
    (B) Analysis: partner E. (1) The ultimate members of LTP 
Partnership are E, P, and Q because they each receive a distributive 
share of the qualified conservation contribution and are not 
partnerships or S corporations. Because E holds a direct interest in 
LTP Partnership, E's relevant basis must be determined in accordance 
with the following formula:

Equation 9 to Paragraph (m)(7)(iii)(B)(1)

R = M x (T / (D + T))

Where:

R = Relevant basis.
M = Modified basis as determined under paragraph (l) of this 
section.

[[Page 54322]]

D = Ultimate member's portion of the adjusted basis in all the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made) as determined under paragraph (m)(2)(iii)(B) 
of this section.
T = Ultimate member's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made, determined 
according to the following formula: A x (B / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
B = Ultimate member's distributive share of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    (2) With respect to E:
    (i) M = $4X.
    (ii) D = $4.36X.
    (iii) A = $18X.
    (iv) B = $2X.
    (v) C = $22X.
    (vi) Thus, T is $1.64X = $18X x ($2X / $22X).
    (vii) Accordingly, E's relevant basis is $1.09X = $4X x ($1.64X / 
($4.36X + $1.64X)).
    (C) Analysis: General rule for UTP Partnership. Because P and Q 
hold interests in an upper-tier partnership, UTP Partnership must first 
determine the portions of P's and Q's modified bases that are allocable 
to UTP Partnership's interest in LTP Partnership. This is to be done 
according to the following formula:

Equation 10 to Paragraph (m)(7)(iii)(C)

G = M x (U / (J + U))

Where:

G = The portion of the ultimate member's modified basis that is 
allocable to the upper-tier partnership's interest in the 
contributing partnership.
M = Modified basis as determined under paragraph (l) of this 
section.
J = Ultimate member's portion of adjusted basis in all the upper-
tier partnership's properties (other than the upper-tier 
partnership's interest in the contributing partnership) as 
determined under paragraph (m)(4)(ii)(A)(2) of this section.
U = Ultimate member's share of the upper-tier partnership's adjusted 
basis in its interest in the contributing partnership, determined 
according to the following formula: H x (B / K).
H = Upper-tier partnership's adjusted basis in its interest in the 
contributing partnership.
B = Ultimate member's distributive share of the qualified 
conservation contribution.
K = Upper-tier partnership's allocated portion of the qualified 
conservation contribution.

    (D) Analysis: Step 1 for P. With respect to P:
    (1) M = $12X.
    (2) J = $3.6X.
    (3) H = $19X.
    (4) B = $6X.
    (5) K = $20X.
    (6) Thus, U is $5.70X = $19X x ($6X / $20X).
    (7) Accordingly, the portion of P's modified basis that is 
allocable to UTP Partnership's interest in LTP Partnership is $7.35X = 
$12X x ($5.70X / ($3.60X + $5.70X)).
    (E) Analysis: Step 1 for Q. With respect to Q:
    (1) M = $8X.
    (2) J = $2.4X.
    (3) H = $19X.
    (4) B = $14X.
    (5) K = $20X.
    (6) Thus, U is $13.30X = $19X x ($14X / $20X).
    (7) Accordingly, the portion of Q's modified basis that is 
allocable to UTP Partnership's interest in LTP Partnership is $6.78X = 
$8X x ($13.30X / ($2.40X + $13.30X)).
    (F) Analysis: General rule for LTP Partnership. Next, LTP 
Partnership must determine P's and Q's relevant bases, which equal the 
portions of the amounts determined under paragraphs (m)(7)(iii)(D) and 
(E) of this section (Example 3) that are allocable to the portion of 
the real property with respect to which the qualified conservation 
contribution was made. This must be done according to the following 
formula:

Equation 11 to Paragraph (m)(7)(iii)(F)

R = G x (V / (L + V))

Where:

R = Relevant basis.
G = Amount determined with respect to item G under paragraph 
(m)(4)(ii)(B) of this section.
L = Upper-tier partnership's portion of adjusted basis in all the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made) as determined under paragraph (m)(2)(iii)(B) 
of this section.
V = Upper-tier partnership's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made, determined 
according to the following formula: A x (K / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
K = Upper-tier partnership's allocated portion of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    (G) Analysis: Step 2 for P. With respect to P:
    (1) G = $7.35X.
    (2) L = $7.64X.
    (3) A = $18X.
    (4) K = $20X.
    (5) C = $22X.
    (6) Thus, V is $16.36X = $18X x ($20X / $22X).
    (7) Accordingly, P's relevant basis is $5.01X = $7.35X x ($16.36X / 
($7.64X + $16.36X)).
    (H) Analysis: Step 2 for Q. With respect to Q:
    (1) G = $6.78X.
    (2) L = $7.64X.
    (3) A = $18X.
    (4) K = $20X.
    (5) C = $22X.
    (6) Thus, V is $16.36X = $18X x ($20X / $22X).
    (7) Accordingly, Q's relevant basis is $4.62X = $6.78X x ($16.36X / 
($7.64X + $16.36X)).
    (I) Analysis: Computation of 2.5 times sum of the relevant bases. 
The ultimate members of LTP Partnership are E, P, and Q. The amount of 
LTP Partnership's qualified conservation contribution is $22X. This 
does not exceed 2.5 times the sum of each of the ultimate member's 
relevant basis, which totals $26.80 ($26.80 = 2.5 x (E's relevant basis 
of 1.09X + P's relevant basis of $5.01X + Q's relevant basis of 
$4.62X)). Therefore, LTP Partnership's contribution is not a disallowed 
qualified conservation contribution (that is, is not disallowed by 
section 170(h)(7) and paragraph (j) of this section). Because UTP 
Partnership receives an allocated portion, it must apply paragraphs (j) 
through (l) of this section and this paragraph (m) to determine whether 
its allocated portion is a disallowed qualified conservation 
contribution. The ultimate members of UTP Partnership are P and Q. The 
amount of UTP Partnership's allocated portion of LTP Partnership's 
qualified conservation contribution is $20X. This does not exceed 2.5 
times the sum of P's and Q's relevant bases, which is $24.08X ($24.08X 
= 2.5 x (P's relevant basis of $5.01X + Q's relevant basis of $4.62X)). 
Therefore, UTP Partnership's allocated portion of LTP Partnership's 
contribution is not a disallowed qualified conservation contribution 
(that is, is not disallowed by section 170(h)(7) and paragraph (j) of 
this section).
    (iv) Example 4--(A) Facts. Individuals V and W form VW Partnership, 
a partnership for Federal income tax purposes. V and W each hold a 
fifty percent interest in all of VW Partnership's items of income, 
gain, loss, deduction, credits, and charitable contributions. On 
formation of VW

[[Page 54323]]

Partnership, V contributes $1,000X cash to VW Partnership and W 
contributes GainProp, which is non-depreciable property with a value of 
$1,000X and basis of $500X. VW Partnership buys real property 
(RealProp), with its $1,000X cash. Later, at a time when VW 
Partnership's basis in RealProp is still $1,000X, and its basis in 
GainProp is still $500X, VW Partnership makes a qualified conservation 
contribution with respect to all of RealProp, which it allocates 
equally to V and W. VW Partnership continues to hold GainProp. V's 
modified basis is $1,000X and W's modified basis is $500X.
    (B) General analysis. V and W are the ultimate members of VW 
Partnership because they each receive a distributive share of the 
qualified conservation contribution and are not partnerships or S 
corporations. Their relevant bases must be determined according to the 
following formula:

Equation 12 to Paragraph (m)(7)(iv)(B)

R = M x (T / (D + T))

Where:

R = Relevant basis.
M = Modified basis as determined under paragraph (l) of this 
section.
D = Ultimate member's portion of the adjusted basis in all of the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made) as determined under paragraph (m)(2)(iii)(B) 
of this section.
T = Ultimate member's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made, determined 
according to the following formula: A x (B / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
B = Ultimate member's distributive share of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    (C) V's relevant basis. With respect to V:
    (1) M = $1,000X.
    (2) D = $250X (half of VW Partnership's adjusted basis in 
GainProp).
    (3) T = $500X (half of VW Partnership's adjusted basis in 
RealProp).
    (4) Accordingly, V's relevant basis is $666.67X = $1,000X x ($500X 
/ ($250X + $500X)).
    (D) W's relevant basis. With respect to W:
    (1) M = $500X.
    (2) D = $250X (half of VW Partnership's basis in GainProp).
    (3) T = $500X (half of VW Partnership's adjusted basis in 
RealProp).
    (4) Accordingly, W's relevant basis is $333.33X = $500X x ($500X / 
($250X + $500X)).
    (v) Example 5--(A) Facts. Assume the same facts as in paragraph 
(m)(7)(iv) of this section (Example 4), except that W does not 
contribute GainProp; instead, W contributes LossProp, which is non-
depreciable property with a value of $1,000X and basis of $2,000X. At 
the time that VW Partnership makes the qualified conservation 
contribution on RealProp, the value of LossProp is still $1,000 and the 
basis of LossProp is still $2,000X. V's modified basis is $1,000X and 
W's modified basis is $2,000X.
    (B) General analysis. V and W are the ultimate members of VW 
Partnership because they each receive a distributive share of the 
qualified conservation contribution and are not partnerships or S 
corporations. Their relevant bases must be determined according to the 
following formula:

Equation 13 to Paragraph (m)(7)(v)(B)

R = M x (T / (D + T))

Where:

R = Relevant basis.
M = Modified basis as determined under paragraph (l) of this 
section.
D = Ultimate member's portion of the adjusted basis in all of the 
contributing partnership's properties (other than the portion of the 
real property with respect to which the qualified conservation 
contribution is made) as determined under paragraph (m)(2)(iii)(B) 
of this section.
T = Ultimate member's share of the contributing partnership's 
adjusted basis in the portion of the real property with respect to 
which the qualified conservation contribution is made, determined 
according to the following formula: A x (B / C).
A = Contributing partnership's adjusted basis in the portion of the 
real property with respect to which the qualified conservation 
contribution is made.
B = Ultimate member's distributive share of the qualified 
conservation contribution.
C = Total amount of the contributing partnership's qualified 
conservation contribution.

    (C) V's relevant basis. With respect to V:
    (1) M = $1,000X.
    (2) D = $500X (half of the $1,000 portion of LossProp's adjusted 
basis that does not exceed LossProp's $1,000X value)
    (3) T = $500X (half of VW Partnership's adjusted basis in RealProp)
    (4) Accordingly, V's relevant basis is $500X = $1,000X x ($500X / 
($500X + $500X)).
    (D) W's relevant basis. With respect to W:
    (1) M = $2,000X.
    (2) D = $1,500X (half of the $1,000 portion LossProp's adjusted 
basis that does not exceed LossProp's $1,000X value, plus all of the 
$1,000 portion of LossProp's adjusted basis in excess of LossProp's 
$1,000X value).
    (3) T = $500X (half of VW Partnership's adjusted basis in 
RealProp).
    (4) Accordingly, W's relevant basis is $500X = $2,000X x ($500X / 
($1,500X + $500X)).
    (n) Exceptions--(1) In general. Paragraph (j) of this section does 
not apply to any qualified conservation contribution that satisfies one 
or more of the three exceptions in this paragraph (n). However, as 
provided in paragraph (j)(5) of this section, there is no presumption 
that a contribution that satisfies one or more of the three exceptions 
in this paragraph (n) is compliant with section 170, any other section 
of the Code, the regulations in this part, or any other guidance. Being 
described in this paragraph (n) is not a safe harbor for purposes of 
any other provision of law or with respect to the value of the 
contribution. Such transactions are subject to adjustment or 
disallowance for any other reason, including failure to satisfy other 
requirements of section 170 or overvaluation of the contribution. In 
addition, taxpayers who engage in transactions that satisfy one or more 
of the three exceptions in this paragraph (n) may nonetheless be 
required to disclose, under Sec.  1.6011-4, the transactions as listed 
transactions.
    (2) Exception for contributions outside three-year holding period--
(i) In general. Paragraph (j) of this section does not apply to any 
qualified conservation contribution by a contributing partnership or 
contributing S corporation made at least three years after the latest 
of--
    (A) The last date on which the contributing partnership or 
contributing S corporation acquired any portion of the real property 
with respect to which such qualified conservation contribution is made;
    (B) The last date on which any partner in the contributing 
partnership or shareholder in the contributing S corporation acquired 
any interest in such partnership or S corporation; and
    (C) If the interest in the contributing partnership is held through 
one or more upper-tier partnerships or upper-tier S corporations--
    (1) The last date on which any such upper-tier partnership or 
upper-tier S corporation acquired any interest in the

[[Page 54324]]

contributing partnership or any other upper-tier partnership; and
    (2) The last date on which any partner or shareholder in any such 
upper-tier partnership or upper-tier S corporation acquired any 
interest in such upper-tier partnership or upper-tier S corporation.
    (ii) Acquisition of partnership interest. For purposes of this 
paragraph (n)(2), an acquisition of any interest in a partnership is 
any variation within the meaning of that term in Sec.  1.706-4(a)(1); 
however, a variation does not include a change in allocations that 
satisfies the requirements of Sec.  1.706-4(b)(1).
    (iii) Acquisition of interest in an S corporation. For purposes of 
this paragraph (n)(2), an acquisition of any interest in an S 
corporation is any transfer, issuance, redemption, or other disposition 
of stock in the S corporation; however, an acquisition does not include 
any issuance or redemption involving all shareholders that does not 
affect the proportionate ownership of any shareholder.
    (iv) Exception is determined at the level of the contributing 
partnership or contributing S corporation. If the contributing 
partnership or contributing S corporation does not satisfy the 
requirements of this paragraph (n)(2), then this paragraph (n)(2) will 
not apply to any person who receives a distributive share or pro rata 
share of the qualified conservation contribution (including an upper-
tier partnership or upper-tier S corporation), regardless of whether 
the person receiving such distributive share or pro rata share would 
have satisfied the requirements of this paragraph (n)(2) if the person 
had been the one to make the qualified conservation contribution.
    (v) Examples. The following examples illustrate the provisions of 
this paragraph (n)(2). For the two examples in this paragraph 
(n)(2)(v), assume that the exceptions in paragraphs (n)(3) and (4) of 
this section do not apply.
    (A) Example 1--(1) Facts. ABC Partnership is a partnership for 
Federal income tax purposes. Since 2015, ABC Partnership's partners 
have been A, an individual, and BC Inc., an S corporation. Since 2015, 
BC Inc.'s shareholders have been B and C, each of whom is an individual 
that is not a nonresident alien. On December 27, 2024, ABC Partnership 
acquires real property. On August 29, 2025, BC Inc. redeems half of B's 
shares in BC Inc. On December 28, 2027, ABC Partnership makes a 
qualified conservation contribution.
    (2) Analysis. Pursuant to paragraph (n)(2)(iii) of this section, BC 
Inc.'s redemption of some of B's shares is treated as an acquisition of 
an interest in BC Inc. for purposes of this paragraph (n)(2). 
Accordingly, ABC Partnership's contribution occurred less than three 
years after the latest acquisition of an interest in a partnership or S 
corporation that held an interest in ABC Partnership, the contributing 
partnership. Therefore, ABC Partnership's contribution fails to satisfy 
the requirements of this paragraph (n)(2) and ABC Partnership must 
apply the provisions of paragraphs (j) through (m) of this section to 
determine whether the contribution is a disallowed qualified 
conservation contribution.
    (B) Example 2--(1) Facts. LTP Partnership is a partnership for 
Federal income tax purposes. Since 2017, LTP Partnership's partners 
have been UTP Partnership, a partnership for Federal income tax 
purposes, and FG Inc., an S corporation. Since 2018, UTP Partnership's 
partners have been individuals D and E, and there has been no variation 
in their ownership. Since 2019, FG Inc.'s shareholders have been F and 
G, each of whom is an individual that is not a nonresident alien. On 
March 15, 2024, LTP Partnership acquires real property. On September 
15, 2026, D dies and D's interest in UTP Partnership passes to D's 
estate. On March 18, 2027, LTP Partnership makes a qualified 
conservation contribution. LTP Partnership allocates all of the 
qualified conservation contribution to FG Inc.
    (2) Analysis. Pursuant to paragraph (n)(2)(ii) of this section, the 
transfer of D's interest in UTP Partnership to D's estate is treated as 
an acquisition of an interest in UTP Partnership for purposes of this 
paragraph (n)(2). Accordingly, LTP Partnership's contribution occurred 
less than three years after the latest acquisition of an interest in a 
partnership or S corporation that held an interest in LTP Partnership, 
the contributing partnership. Therefore, LTP Partnership's contribution 
fails to satisfy the requirement of this paragraph (n)(2). Pursuant to 
paragraph (n)(2)(iv) of this section, FG Inc. cannot avail itself of 
this paragraph (n)(2) with respect to its allocated portion of LTP 
Partnership's contribution. Accordingly, FG Inc. must apply the 
provisions of paragraphs (j) through (m) of this section to determine 
whether its allocated portion is a disallowed qualified conservation 
contribution.
    (3) Exception for family partnerships and S corporations--(i) 
General rule. Paragraph (j) of this section does not apply with respect 
to any qualified conservation contribution made by a contributing 
partnership or contributing S corporation if at least 90 percent of the 
interests in the contributing partnership or contributing S corporation 
are held by an individual and members of the family of such individual 
and the contributing partnership or contributing S corporation meets 
the requirements of this paragraph (n)(3).
    (ii) Ninety percent of the interests--(A) Family partnerships. In 
the case of a contributing partnership, at least 90 percent of the 
interests in the contributing partnership are held by an individual and 
members of the family of such individual if, at the time of the 
qualified conservation contribution, at least 90 percent of the 
interests in capital and profits in such partnership are held, directly 
or indirectly, by an individual and members of the family of such 
individual.
    (B) Family S corporations. In the case of a contributing S 
corporation, at least 90 percent of the interests in the contributing S 
corporation are held by an individual and members of the family of such 
individual if, at the time of the qualified conservation contribution, 
at least 90 percent of the total value and at least 90 percent of the 
total voting power of the outstanding stock in such S corporation are 
held by an individual and members of the family of such individual.
    (iii) Members of the family. For purposes of this paragraph (n)(3), 
the term members of the family means, with respect to any individual--
    (A) The spouse of such individual;
    (B) Any individual who bears a relationship to such individual that 
is described in section 152(d)(2)(A) through (G) of the Code;
    (C) The estate of a deceased individual who was described in 
paragraph (n)(3)(iii)(A) or (B) of this section at the time of death; 
and
    (D) A trust all of the beneficiaries of which are individuals 
described in paragraph (n)(3)(iii)(A) or (B) of this section, treating 
as beneficiaries for this purpose those persons who currently must or 
may receive income or principal from the trust and those persons who 
would succeed to the property of the trust if the trust were to 
terminate immediately before the qualified conservation contribution.
    (iv) Anti-abuse rules--(A) Holding period. This paragraph (n)(3) 
does not apply unless at least 90 percent of the interests in the 
property with respect to which the qualified conservation contribution 
was made were owned, directly or indirectly, by an individual and 
members of the family of that individual for at least one year prior to 
the date of the contribution. The members of the family during that 
year need not be the same members of the family that own an interest at 
the time

[[Page 54325]]

of the qualified conservation contribution; however, at least one 
individual must own an interest for the entire year, and at least 90 
percent of the interests in the property must be owned, directly or 
indirectly, during that year by that individual and members of that 
individual's family. Solely for purposes of this paragraph 
(n)(3)(iv)(A), section 1223(1) and (2) of the Code do not apply in 
determining whether at least ninety percent of the interests in the 
property with respect to which the qualified conservation contribution 
was made were owned, directly or indirectly, by one individual and 
members of the family of that individual for at least one year prior to 
the date of the contribution. This paragraph (n)(3)(iv)(A) does not 
apply if the entire amount of the qualified conservation contribution 
is limited by section 170(e) to the contributing partnership's or 
contributing S corporation's adjusted basis in the qualified 
conservation contribution.
    (B) Allocations. This paragraph (n)(3) does not apply unless at 
least 90 percent of the qualified conservation contribution is 
allocated to the individual and all members of the family who own at 
least 90 percent of the interests in the contributing partnership or 
contributing S corporation under paragraph (n)(3)(ii) of this section.
    (v) Exception is determined at the level of the contributing 
partnership or contributing S corporation. If the contributing 
partnership or contributing S corporation satisfies the requirements of 
this paragraph (n)(3), then any upper-tier partnership or upper-tier S 
corporation need not apply paragraphs (j) through (m) of this section 
and this paragraph (n) to its allocated portions of such contribution. 
If the contributing partnership or contributing S corporation does not 
satisfy the requirements of this paragraph (n)(3), then the exception 
in this paragraph (n)(3) will not apply to any person who receives a 
distributive share or pro rata share of the qualified conservation 
contribution (including an upper-tier partnership or upper-tier S 
corporation), regardless of whether the person receiving such 
distributive share or pro rata share would have satisfied the 
requirements of this paragraph (n)(3) if the person had been the one to 
make the contribution.
    (vi) Examples. The following examples illustrate the provisions of 
this paragraph (n)(3). For the two examples in this paragraph 
(n)(3)(vi), assume that the exceptions in paragraphs (n)(2) and (4) of 
this section do not apply.
    (A) Example 1--(1) Facts. Individual A and A's sibling B acquire 
real property by purchase on July 5, 2024. On September 14, 2024, B 
transfers its interest in the real property to B's child C. On February 
21, 2025, A and C transfer their interests in the real property to AC 
Partnership, a partnership for Federal income tax purposes whose only 
partners are A and C. On March 18, 2025, A's stepfather D becomes a 
partner in AC Partnership in exchange for a capital contribution. On 
September 15, 2025, AC Partnership makes a qualified conservation 
contribution on the real property. AC Partnership never had any 
partners other than A, C, and D.
    (2) Analysis. B, C, and D qualify as members of the family with 
respect to A. Accordingly, as of the time of the qualified conservation 
contribution, at least 90 percent of the interests in capital and 
profits of AC Partnership were owned by an individual and members of 
that individual's family. In addition, at least 90 percent of the 
interests in the property with respect to which the qualified 
conservation contribution was made were owned, directly and indirectly, 
by A and members of A's family for at least one year prior to the date 
of the contribution. Moreover, at least 90 percent of the contribution 
is allocated to A and members of A's family. Accordingly, the 
requirements of this paragraph (n)(3) are satisfied, and the 
Disallowance Rule in section 170(h)(7)(A) and paragraph (j) of this 
section does not apply.
    (B) Example 2--(1) Facts. LTP Partnership is a partnership for 
Federal income tax purposes whose partners are EF Inc., an S 
corporation, and UTP Partnership, a partnership for Federal income tax 
purposes. EF Inc. and UTP Partnership each hold a 50 percent interest 
in the profits and capital of LTP Partnership. The shareholders of EF 
Inc. are E and E's sibling F. The partners of UTP Partnership are G and 
G's child H. E and F are not related to G and H. LTP Partnership has 
held real property since 2019. On July 5, 2024, LTP Partnership 
distributes half of the acres of its real property to EF Inc., and the 
remaining acres to UTP Partnership. On October 21, 2024, EF Inc., makes 
a qualified conservation contribution on the real property it received 
from LTP Partnership. The amount of EF Inc.'s qualified conservation 
contribution is not limited by section 170(e).
    (2) Analysis. F qualifies as a member of the family with respect to 
E. Accordingly, as of the time of EF Inc.'s qualified conservation 
contribution, EF Inc. was owned at least 90 percent by an individual 
and members of that individual's family. In addition, at least 90 
percent of EF Inc's qualified conservation contribution is allocated to 
E and members of E's family. However, E and members of E's family 
failed to own at least 90 percent of the property with respect to which 
the qualified conservation contribution was made for at least one year 
prior to the date of the contribution. In particular, G and H (who are 
not members of the family with respect to E or F) indirectly owned a 50 
percent interest in the property until July 5, 2024. Accordingly, the 
requirements of this paragraph (n)(3) are not satisfied. EF Inc. must 
apply the provisions of paragraphs (j) through (m) of this section to 
determine whether the contribution is a disallowed qualified 
conservation contribution. If the entire amount of EF Inc.'s qualified 
conservation contribution had been limited by section 170(e) to EF 
Inc.'s adjusted basis in the qualified conservation contribution, then 
paragraph (n)(3)(iv)(A) of this section would not have applied; 
accordingly, the requirements of this paragraph (n)(3) would have been 
satisfied, and the Disallowance Rule in section 170(h)(7)(A) and 
paragraph (j) of this section would not have applied.
    (4) Exception for contributions to preserve certified historic 
structures. Paragraph (j) of this section does not apply to any 
qualified conservation contribution the conservation purpose of which 
is the preservation of any building that is a certified historic 
structure (as defined in section 170(h)(4)(C)). See Sec.  1.170A-
16(f)(6) for special reporting requirements for a contribution that 
meets the exception in this paragraph (n)(4).
    (o) Applicability dates--(1) In general. Except as provided in 
paragraphs (g)(4)(ii), (i), and (o)(2) of this section, paragraphs (a) 
through (i) of this section apply only to contributions made on or 
after December 18, 1980. Paragraphs (j) through (n) of this section 
apply to contributions made after December 29, 2022.
    (2) Exception. Paragraph (h)(4)(ii) of this section applies on and 
after June 1, 2023.

charitable contributions.

* * * * *
    (c) * * *
    (3) * * *
    (v) If a number can be inserted into any box on Form 8283 (Section 
A), the number inserted in the box on Form 8283 (Section A). 
Alternatively, taxpayers may attach a statement to the Form 8283 
explaining why a number cannot be inserted. Nothing in this paragraph 
(c)(3)(v) precludes a taxpayer from both inserting the number in the 
appropriate box on Form 8283 (Section A) and including an attached 
statement explaining any additional information regarding the number. 
Taxpayers may not respond to a request for information on Form 8283 
(Section A) with nonresponsive language; for example, by indicating 
that the requested information is available upon request or will be 
provided upon request. The inclusion of such nonresponsive language in 
response to a request for information on Form 8283 (Section A) may be 
treated by the IRS as being an incomplete filing of Form 8283; and

    (viii) In the case of a partnership or S corporation that makes a 
qualified conservation contribution, the sum of each ultimate member's 
relevant basis, computed in accordance with Sec.  1.170A-14(j) through 
(m), but only:
    (A) For contributions described in section 170(h)(7)(E) and Sec.  
1.170A-14(n)(4) (for contributions to preserve certified historic 
structures), regardless of whether they are also described in section 
170(h)(7)(C) and Sec.  1.170A-14(n)(2) (for contributions made outside 
of the three-year holding period) and/or section 170(h)(7)(D) and Sec.  
1.170A-14(n)(3) (for contributions made by certain family partnerships 
or S corporations); and
    (B) For all contributions not described in section 170(h)(7)(E) and 
Sec.  1.170A-14(n)(4), provided they are not described in section 
170(h)(7)(C) and Sec.  1.170A-14(n)(2) (for contributions made outside 
of the three-year holding period) and/or section 170(h)(7)(D) and Sec.  
1.170A-14(n)(3) (for contributions made by certain family partnerships 
or S corporations);
    (ix) If a number can be inserted into any box on Form 8283 (Section 
B), the number inserted in the box on Form 8283 (Section B). 
Alternatively, taxpayers may attach a statement to the Form 8283 
explaining why a number cannot be inserted. Nothing in this paragraph 
(d)(3)(ix) precludes a taxpayer from both inserting the number in the 
appropriate box on Form 8283 (Section B) and including an attached 
statement explaining any additional information regarding the number. 
Taxpayers may not respond to a request for information on Form 8283 
(Section B) with nonresponsive language; for example, by indicating 
that the requested information is available upon request or will be 
provided upon request. The inclusion of such nonresponsive language in 
response to a request for information on Form 8283 (Section B) may be 
treated by the IRS as being an incomplete filing of Form 8283; and
* * * * *
    (f) * * *
    (4) Partners and S corporation shareholders--(i) Form 8283 (Section 
A or Section B) must be provided to partners and S corporation 
shareholders. If the donor is a partnership or an S corporation, the 
donor must provide a copy of its completed Form 8283 (Section A or 
Section B) to every partner or shareholder who receives an allocation 
of a charitable contribution under section 170 for the property 
described in Form 8283 (Section A or Section B). Similarly, a recipient 
partner that is a partnership or S corporation must provide a copy of 
the donor's completed Form 8283 (Section A or Section B) to each of its 
partners or shareholders who receives an allocation of the charitable 
contribution, and so on through any additional tiers.
    (ii) Partners and S corporation shareholders must attach Forms 8283 
(Section A or Section B) to return. A partner of a partnership or 
shareholder of an S corporation who receives an allocation of a 
charitable contribution under section 170 for property to which 
paragraph (c), (d), or (e) of this section applies must attach to the 
return on which the contribution is claimed a copy of each Form 8283 
that must be provided to them under paragraph (f)(4)(i) or (iii) of 
this section.
    (iii) Partners and S corporation shareholders must file separate 
Forms 8283 and provide copies to any partners--(A) In general. Subject 
to paragraph (f)(4)(iii)(B) of this section, every partner of a 
partnership (including a partner that is itself a partnership or S 
corporation) or shareholder of an S corporation that receives an 
allocation of a charitable contribution under section 170 for which 
paragraph (c), (d), or (e) of this section applies must complete a 
separate Form 8283 with any information required by Form 8283 and the 
instructions to Form 8283. In the case of a partner that is itself a 
partnership or S corporation, that partnership or S corporation must 
provide a copy of its completed separate Form 8283 to every partner or 
shareholder who receives an allocation of the charitable contribution, 
and so on through any additional tiers. The partner or shareholder must 
attach its separate Form 8283 to the return on which the contribution 
is claimed, in addition to the copy of each Form 8283 that the partner 
or shareholder is required to attach pursuant to paragraph (f)(4)(ii) 
of this section.
    (B) Conservation contributions. The terms defined in Sec.  1.170A-
14(j)(3) apply for purposes of this paragraph (f)(4)(iii)(B). In the 
case of a qualified conservation contribution that is made by a 
partnership or S corporation, an ultimate member's separate Form 8283 
must include their own relevant basis. An upper-tier partnership's or 
upper-tier S corporation's separate Form 8283 must include the sum of 
each of its ultimate member's relevant basis (as computed in accordance 
with Sec.  1.170A-14(j) through (m)). This paragraph (f)(4)(iii)(B) 
does not apply to contributions described in section 170(h)(7)(C) and 
Sec.  1.170A-14(n)(2) (for contributions made outside of the three-year 
holding period) or section 170(h)(7)(D) and Sec.  1.170A-14(n)(3) (for 
contributions made by certain family partnerships or S corporations), 
provided that they are not also described in section 170(h)(7)(E) and 
Sec.  1.170A-14(n)(4) (for contributions to preserve certified historic 
structures), in which case this paragraph (f)(4)(iii)(B) does apply.
* * * * *
    (6) Conservation contributions by pass-through entities preserving 
certified historic structures--(i) In general. The terms defined in 
Sec.  1.170A-14(j)(3) apply for purposes of this paragraph (f)(6). For 
any contribution described in paragraph (f)(6)(ii) of this section, 
pursuant to section 170(f)(19), no deduction is allowed under section 
170 or any other provision of the Code

[[Page 54327]]

under which deductions are allowable to pass-through entities with 
respect to such contribution unless the contributing partnership, the 
contributing S corporation, the upper-tier partnership, or the upper-
tier S corporation, respectively--
    (A) Includes on its return for the taxable year in which the 
contribution is made a statement that it made such a contribution or 
received such allocated portion, as described in paragraph (f)(6)(iii) 
of this section; and
    (B) Provides such information about the contribution as the 
Secretary of the Treasury or her delegate may require in guidance, 
forms, or instructions.
    (ii) Contributions to which this paragraph (f)(6) applies. This 
paragraph (f)(6) applies to any qualified conservation contribution (as 
defined in section 170(h)(1) and Sec.  1.170A-14):
    (A) The conservation purpose of which is preservation of a building 
that is a certified historic structure (as defined in section 
170(h)(4)(C));
    (B) That is either:
    (1) Made by a contributing partnership or contributing S 
corporation (as defined in Sec.  1.170A-14(j)(3)(iv)); or
    (2) Is an allocated portion (as defined in Sec.  1.170A-
14(j)(3)(i)) of an upper-tier partnership (as defined in Sec.  1.170A-
14(j)(3)(xi)) or upper-tier S corporation (as defined in Sec.  1.170A-
14(j)(3)(xii)); and
    (C) The amount of such contribution (as defined in Sec.  1.170A-
14(j)(3)(ii)) or such allocated portion (as defined in Sec.  1.170A-
14(j)(3)(i)) exceeds 2.5 times the sum of each ultimate member's 
relevant basis (as defined in Sec.  1.170A-14(j) through (m)).
    (iii) Required information. A partnership or S corporation 
satisfies the requirements of section 170(f)(19)(A) and paragraph 
(f)(6)(i) of this section by filing a completed Form 8283, including 
information about relevant basis, in accordance with section 170, the 
regulations under section 170, and the instructions to Form 8283.
    (g) Applicability dates--(1) In general. Except as provided in 
paragraph (g)(2) of this section, this section applies to contributions 
made after July 30, 2018.
    (2) Certain paragraphs. Paragraphs (c)(3)(v), (d)(3)(viii) and 
(ix), and (f)(4) and (6) of this section apply to taxable years ending 
on or after November 20, 2023.

contribution is a disallowed qualified conservation contribution within 
the meaning of Sec.  1.170A-14(j)(3)(vii)) by a partnership that is 
allocated to an upper-tier partnership, the upper-tier partnership must 
allocate the contribution among its partners in accordance with their 
interests in the qualified conservation contribution at the time of day 
at which the qualified conservation contribution was made, regardless 
of the general rule of section 706(d)(3). Pursuant to Sec.  1.706-
