Single-Employer Defined Benefit Plans

AGENCY: Internal Revenue Service (IRS), Treasury.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: This document contains proposed regulations that would modify

[[Page 53804]]

rules in the existing regulations relating to the minimum funding 
requirement applicable to single-employer defined benefit pension 
plans. The modifications include changes to the rules relating to the 
determination of a plan's target normal cost and funding target and 
would implement certain statutory amendments that have not yet been 
reflected in the regulations. These proposed regulations would affect 
participants in, beneficiaries of, employers maintaining, and 
administrators of single-employer defined benefit plans.

SUPPLEMENTARY INFORMATION:

Authority

    The proposed regulations are issued under the delegation of 
authority in section 430(g)(3)(B) of the Internal Revenue Code (Code), 
which provides that a plan may determine the value of plan assets on 
the basis of the averaging of fair market values, but only if that 
method is permitted under regulations prescribed by the Secretary of 
the Treasury or the Secretary's delegate (Secretary); and section 
430(h)(3), which provides that, generally, the Secretary shall 
prescribe by regulation mortality tables to be used in determining any 
present value or making any computation under section 430.
    In addition, the proposed regulations are issued under the 
delegation of authority in section 7805. Section 7805(a) directs the 
Secretary of the Treasury or his delegate to prescribe all needful 
rules and regulations for the enforcement of that section and other 
provisions of the Code, including such rules and regulations as may be 
necessary by reason of any alteration of law relating to internal 
revenue.

Background

    This document contains proposed amendments to the Income Tax 
Regulations (26 CFR part 1) under section 430 of the Code, which was 
added by the Pension Protection Act of 2006, Public Law 109-280, 120 
Stat. 780 (2006). The proposed amendments to the regulations primarily 
reflect changes to section 430 of the Code made by: (1) the Worker, 
Retiree, and Employer Recovery Act of 2008 (WRERA `08), Public Law 110-
458, 122 Stat. 5092 (2008); (2) the Setting Every Community Up for 
Retirement Enhancement Act of 2019 (SECURE Act), Division O of the 
Further Consolidated Appropriations Act, 2020, Public Law 116-94, 133 
Stat. 2534 (2019); and (3) the SECURE 2.0 Act of 2022 (SECURE 2.0 Act), 
Division T of the Consolidated Appropriations Act, 2023, Public Law 
117-328, 136 Stat. 4459 (2022).

A. Plan Qualification Timing Rules Under Section 401(b)

    Section 401(b)(1), as amended by section 201 of the SECURE Act, 
provides that a plan is considered as satisfying the qualification 
requirements of section 401(a) for the period beginning with the date 
on which it was put into effect, or for the period beginning with the 
earlier of the date on which there was adopted or put into effect any 
amendment that caused the plan to fail to satisfy those requirements, 
and ending with the time prescribed by law for filing the return of the 
employer for his taxable year in which the plan or amendment was 
adopted (including extensions) or any later time as the Secretary may 
designate, if all provisions of the plan that are necessary to satisfy 
those requirements are in effect by the end of that period and have 
been made effective for all purposes for the whole of that period.
    Section 401(b)(2), as added by section 201 of the SECURE Act and 
amended by Section 317 of the SECURE 2.0 Act, provides that if an 
employer adopts a plan after the close of a taxable year but before the 
time prescribed by law for filing the return of the employer for the 
taxable year (including extensions), then the employer may elect to 
treat the plan as having been adopted as of the last day of the taxable 
year.
    Section 401(b)(3), as added by Section 316 of the SECURE 2.0 Act, 
provides that if (A) an employer amends a plan to increase benefits 
accrued under the plan effective as of any date during the immediately 
preceding plan year (other than increasing the amount of matching 
contributions), (B) that amendment would not otherwise cause the plan 
to fail to meet any of the requirements of sections 401 through 436 of 
the Code, and (C) that amendment is adopted before the time prescribed 
by law for filing the return of the employer for the taxable year 
(including extensions) which includes the effective date of the 
amendment, then the employer may elect to treat that amendment as 
having been adopted as of the last day of the plan year in which the 
amendment is effective.
    Section 1.401(b)-1 provides rules regarding remedial amendments 
under section 401(b). Under Sec.  1.401(b)-1(a), a plan that does not 
satisfy the requirements of section 401(a) on any date solely as a 
result of a disqualifying provision (as determined under Sec.  
1.401(b)-1(b)) is considered to have satisfied those requirements on 
that date if, on or before the end of the remedial amendment period (as 
defined in Sec.  1.401(b)-1(d) through (f) with respect to the 
disqualifying provision), all provisions of the plan that are necessary 
to satisfy all requirements under section 401(a) are in effect and have 
been made effective for all purposes for the entire remedial amendment 
period. The second sentence of Sec.  1.401(b)-1(a) notes that under 
some facts and circumstances, it may not be possible to amend a plan 
retroactively so that all provisions of the plan which are necessary to 
satisfy the requirements of section 401(a) are in fact made effective 
for the whole remedial amendment period.\1\
---------------------------------------------------------------------------

    \1\ In these circumstances, the plan would have to be operated 
in accordance with the expected future amendment prior to when the 
amendment is adopted.
---------------------------------------------------------------------------

    Pursuant to Sec.  1.401(b)-1(d)(2), the remedial amendment period 
generally ends with the time prescribed by law, including extensions, 
for filing the income tax return (or partnership return of income) of 
the employer for the employer's taxable year in which falls the latest 
of: (1) the date on which the remedial amendment period begins, (2) the 
date on which the disqualifying provision is adopted, or (3) the date 
on

[[Page 53805]]

which the disqualifying provision is made effective. However, under 
Sec.  1.401(b)-1(d)(2), the Commissioner may extend the remedial 
amendment period.
    Revenue Procedure 2022-40, 2022-47 I.R.B. 487, extended the 
expiration of the remedial amendment period for a disqualifying 
provision with respect to a provision of a new plan or the absence of a 
provision from a new plan to the last day of the second calendar year 
following the calendar year in which the plan is put into effect. In 
addition, many deadlines for plan amendments made pursuant to specific 
legislative changes have been further extended in the corresponding 
legislation. See, for example, section 501 of the SECURE 2.0 Act.

B. Minimum Funding Requirements and Related Provisions for Single-
Employer Defined Benefit Plans

Statutory Provisions
    Section 412 provides minimum funding requirements that generally 
apply for pension plans (including both defined benefit pension plans 
and money purchase pension plans). Pursuant to section 412(a)(2)(A), 
section 430 specifies the minimum funding requirements that apply to 
single-employer defined benefit pension plans (including multiple-
employer plans) other than CSEC plans described in section 414(y).
    Section 412(d)(1) provides that if the funding method or a plan 
year for a plan is changed, the change will take effect only if 
approved by the Secretary.\2\ Section 412(d)(2) provides that, for 
purposes of section 412, any amendment applying to a plan year which is 
adopted no later than 2\1/2\ months after the close of the plan year 
(or, in the case of a multiemployer plan, no later than 2 years after 
the close of such plan year), does not reduce the accrued benefit of 
any participant determined as of the beginning of the first plan year 
to which the amendment applies, and does not reduce the accrued benefit 
of any participant determined as of the time of adoption except to the 
extent required by the circumstances, will, at the election of the plan 
administrator, be deemed to have been made on the first day of the plan 
year.
---------------------------------------------------------------------------

    \2\ The Secretary has prescribed procedures allowing plans 
subject to section 412 to receive automatic approval to change their 
funding method in limited circumstances. See Rev. Proc. 2017-56, 
2017-44 IRB 465 (applicable to single-employer plans), and Rev. 
Proc. 2000-40, 2000-42 IRB 357 (applicable to multiemployer plans). 
The Secretary has also prescribed procedures allowing plans to 
receive automatic approval to change their plan year if certain 
conditions are met. See Rev. Proc. 87-27, 1987-1 CB 769, as amended 
by Ann. 88-97, 1988-26 IRB 47.
---------------------------------------------------------------------------

    Under section 430, the minimum required contribution for a plan 
year is a function of the target normal cost under section 430(b)(1), 
shortfall amortization charge under section 430(c)(1), funding target 
under section 430(d)(1), waiver amortization charge under section 
430(e)(1), and value of plan assets under section 430(g)(3). If the 
value of plan assets (less the sum of the plan's prefunding balance and 
funding standard carryover balance determined under section 430(f)) is 
less than the funding target, section 430(a)(1) defines the minimum 
required contribution as the sum of the plan's target normal cost and 
the shortfall and waiver amortization charges for the plan year. If the 
value of plan assets (less the sum of the plan's prefunding balance and 
funding standard carryover balance) equals or exceeds the funding 
target, section 430(a)(2) defines the minimum required contribution as 
the plan's target normal cost for the plan year reduced (but not below 
zero) by the amount of any such excess.
    Section 430(b)(1) as amended by WRERA `08, provides that, except as 
otherwise provided in section 430(i)(2) (regarding a plan that is in 
at-risk status), a plan's target normal cost for a plan year is the sum 
of the present value of all benefits expected to accrue or be earned 
under the plan during the plan year (with any increase in any benefit 
attributable to services performed in a preceding plan year by reason 
of a compensation increase during the current plan year treated as 
having accrued during the current plan year) and the amount of plan-
related expenses expected to be paid from plan assets during the plan 
year, reduced by the amount of mandatory employee contributions 
expected to be made during the plan year.
    Section 430(d)(1) provides that, except as otherwise provided in 
section 430(i)(1) (regarding a plan that is in at-risk status), a 
plan's funding target for a plan year is the present value of all 
benefits accrued or earned under the plan as of the beginning of the 
plan year.
    Under section 430(h)(5), if, with respect to a single-employer 
defined benefit plan, the aggregate unfunded vested benefits as of the 
close of the preceding plan year (combined with the unfunded vested 
benefits for all other plans maintained by the contributing sponsors 
and members of such sponsors' controlled groups) exceeded $50 million, 
then certain changes in actuarial assumptions must be approved by the 
Secretary. The changes in actuarial assumptions that require approval 
are changes that result in a decrease in the funding shortfall of the 
plan for the current plan year (determined after taking into account 
any changes in interest rate and mortality table) that exceeds $50 
million (or that exceeds $5 million and that is 5 percent or more of 
the funding target of the plan before that change).
    Section 404(o)(6) provides that any computations under section 
404(o), which relates to the deduction for contributions to a single-
employer defined benefit plan, must use the same actuarial assumptions 
that are used for the plan year under section 430, except that the 
interest rate corridor under section 430(h)(2)(C)(iv) does not apply, 
and section 404(o)(7) provides that any term used in section 404(o) 
which is also used in section 430 has the same meaning given to that 
term by section 430. Thus, except for the difference in interest rates, 
the funding target and target normal cost under section 430 (determined 
taking into account plan provisions that are recognized under the rules 
of section 430) are also used to determine the maximum deductible 
contributions under section 404(o).
    Section 436(c)(1) provides that, generally, no amendment to a 
defined benefit plan which is a single-employer plan which has the 
effect of increasing liabilities of the plan by reason of increases in 
benefits, establishment of new benefits, changing the rate of benefit 
accrual, or changing the rate at which benefits become nonforfeitable 
may take effect during any plan year if the adjusted funding target 
attainment percentage (AFTAP) for such plan year is less than 80 
percent, or would be less than 80 percent taking into account the 
amendment.\3\ However, section 436(c)(2) provides that such an 
amendment can take effect if the plan sponsor makes a contribution (in 
addition to the minimum required contribution) equal to the amount of 
the increase in the funding target of the plan for the plan year 
attributable to the amendment (if the AFTAP is less than 80 percent) or 
(in other cases) the amount necessary to result in an AFTAP of 80 
percent.
---------------------------------------------------------------------------

    \3\ Section 436(c)(3) provides for a limited exception for 
certain benefit increases under a formula which is not based on a 
participant's compensation.
---------------------------------------------------------------------------

Regulatory Provisions
    On October 15, 2009, final regulations regarding the determination 
of the target normal cost under section 430(b) and the funding target 
under section 430(d) were published in the Federal Register

[[Page 53806]]

(TD 9467, 74 FR 53004). Those regulations apply to plan years beginning 
on or after January 1, 2010.
    Section 1.430(d)-1(b)(1)(i) provides that, subject to the 
adjustments in Sec.  1.430(d)-1(b)(1)(iii), the target normal cost of a 
defined benefit plan that is not in at-risk status under section 430(i) 
for a plan year is the present value (determined as of the valuation 
date) of all benefits under the plan that accrue during, are earned 
during, or are otherwise allocated to service for the plan year.
    Section 1.430(d)-1(b)(1)(iii)(A) provides that the target normal 
cost of the plan for the plan year is adjusted (not below zero) by 
adding the amount of plan-related expenses expected to be paid from 
plan assets during the plan year and subtracting the amount of 
mandatory employee contributions that are expected to be made during 
the plan year. Section 1.430(d)-1(b)(1)(iii)(B) is reserved for a 
definition of plan-related expenses.
    Under Sec.  1.430(d)-1(d)(1)(i), a plan's funding target and target 
normal cost for a plan year generally are determined based on plan 
provisions that are adopted no later than the valuation date for the 
plan year and that take effect on or before the last day of the plan 
year.
    Section 1.430(d)-1(d)(1)(ii) provides rules regarding the impact of 
an election under section 412(d)(2), which is available with respect to 
a plan amendment adopted no later than 2\1/2\ months after the close of 
the plan year (including an amendment adopted during the plan year). 
Under Sec.  1.430(d)-1(d)(1)(ii), if a plan administrator makes the 
election described in section 412(d)(2) with respect to a plan 
amendment, then the plan amendment is treated as having been adopted on 
the first day of the plan year for purposes of Sec.  1.430(d)-1(d). 
However, because a section 412(d)(2) election merely deems the 
amendment to have been made on the first day of the plan year, it does 
not determine when the plan amendment takes effect. Accordingly, 
regardless of whether a section 412(d)(2) election is made, an 
amendment is taken into account for the plan year only if it takes 
effect by the last day of the plan year.
    Section 1.430(d)-1(d)(1)(iii) provides that, for purposes of Sec.  
1.430(d)-1(d)(1), the determination of whether an amendment that 
increases benefits takes effect and when it takes effect is determined 
in accordance with the rules of section 436(c) and Sec.  1.436-1(c)(5). 
Section 1.436-1(c)(5) provides that, for purposes of section 436(c) and 
Sec.  1.436-1(c), in the case of an amendment that increases benefits, 
the amendment takes effect under a plan on the first date on which any 
individual who is or could be a participant or beneficiary under the 
plan would obtain a legal right to the increased benefit if the 
individual were on that date to satisfy the applicable requirements for 
entitlement to the benefit (such as the attainment of any age, 
performance of any service, receipt or derivation of any compensation, 
or the occurrence of death, disability, or severance from employment). 
Section 1.430(d)-1(d)(1)(iii) similarly provides that in the case of an 
amendment that decreases benefits, the amendment takes effect under a 
plan on the first date on which the benefits of any individual who is 
or could be a participant or beneficiary under the plan would be less 
valuable than those benefits would be under the pre-amendment plan 
provisions if the individual were on that date to satisfy the 
applicable conditions for the benefits.
    Section 1.430(d)-1(d)(2) provides that, in the case of a plan 
amendment that is not required to be taken into account under the rules 
of Sec.  1.430(d)-1(d)(1) because it is adopted after the valuation 
date for the plan year, the plan amendment must be taken into account 
in determining a plan's funding target and target normal cost for the 
plan year if the amendment (i) takes effect by the last day of the plan 
year; (ii) increases the liabilities of the plan by reason of increases 
in current benefits, establishment of new benefits, changing the rate 
of benefit accrual, or changing the rate at which benefits become 
nonforfeitable; and (iii) would not be permitted to take effect under a 
modified version of the rules of section 436(c). The modified version 
of the section 436(c) rules is set forth in Sec.  1.430(d)-
1(d)(2)(iii), which provides that those rules are applied by treating 
the increase in the target normal cost for the plan year attributable 
to the amendment (and all other amendments that must be taken into 
account solely because of the application of the rules in Sec.  
1.430(d)-1(d)(2)) as if the increase were an increase in the funding 
target for the plan year, and by taking into account all unpredictable 
contingent event benefits permitted to be paid for unpredictable 
contingent events that occurred during the current plan year and all 
plan amendments that took effect in the current plan year (including 
all amendments to which Sec.  1.430(d)-1(d)(2) applies for the plan 
year).

C. Actuarial Assumptions

    Section 1.430(d)-1(f)(1)(i) provides that the determination of any 
present value or other computation under section 430 and this section 
must be made on the basis of actuarial assumptions and a funding 
method. Section 1.430(d)-1(f)(1)(ii) provides that actuarial 
assumptions established for a plan year cannot subsequently be changed 
for that plan year unless the Commissioner determines that the 
assumptions that were initially used are unreasonable. Similarly, a 
funding method established for a plan year cannot subsequently be 
changed for that plan year unless the Commissioner determines that the 
initial use of that funding method for that plan year is impermissible. 
Section 1.430(d)-1(f)(1)(iii) provides that generally, the actuarial 
assumptions and funding method for a plan year are established by the 
filing of an actuarial report under section 6059 (Schedule SB of Form 
5500, Annual Return/Report of Employee Benefit Plan).
    Section 1.430(d)-1(f)(3) provides that, in the case of actuarial 
assumptions other than those specified in sections 430(h)(2), 
430(h)(3), and 430(i), each of those actuarial assumptions must be 
reasonable (taking into account the experience of the plan and 
reasonable expectations). In addition, the actuarial assumptions (other 
than those specified in sections 430(h)(2), 430(h)(3), and 430(i)) 
must, in combination, offer the plan's enrolled actuary's best estimate 
of anticipated experience under the plan based on information 
determined as of the valuation date.
    Section 1.430(d)-1(f)(4)(ii) provides that any determination of 
present value or any other computation under that section must take 
into account the probability that future benefit payments under the 
plan will be made in the form of any optional form of benefit provided 
under the plan (including single-sum distributions), determined on the 
basis of the plan's experience and other related assumptions, in 
accordance with Sec.  1.430(d)-1(f)(3); and must take into account any 
difference in the present value of future benefit payments that results 
from the use of actuarial assumptions in determining the amount of 
benefit payments in any such optional form of benefit that are 
different from those prescribed by section 430(h).
    Section 1.430(d)-1(f)(4)(iii)(A) provides that, in the case of a 
distribution that is subject to section 417(e)(3) and that is 
determined using the applicable interest rates and applicable mortality 
table under section 417(e)(3), for purposes of applying Sec.  1.430(d)-
1(f)(4)(ii), the computation of the present value of that distribution 
is treated as having taken into account any difference in present value 
that results from the use of actuarial assumptions that are different 
from those prescribed

[[Page 53807]]

by section 430(h) (as required under Sec.  1.430(d)-1(f)(4)(ii)(B)) if 
and only if the present value of the distribution is determined in 
accordance with Sec.  1.430(d)-1(f)(4)(iii).
    Section 1.430(d)-1(f)(4)(iii)(B) provides that, generally, the 
present value of a distribution is determined in accordance with Sec.  
1.430(d)-1(f)(4)(iii) if that present value is determined as the 
present value, using special actuarial assumptions, of the annuity 
(either the deferred or immediate annuity) which is used under the plan 
to determine the amount of the distribution. Under these special 
assumptions, for the period beginning with the expected annuity 
starting date for the distribution, the current applicable mortality 
table under section 417(e)(3) that would apply to a distribution with 
an annuity starting date occurring on the valuation date is substituted 
for the mortality table under section 430(h)(3) that would otherwise be 
used. In addition, under these special assumptions, the valuation 
interest rates under section 430(h)(2) are used for purposes of 
discounting the projected annuity payments from their expected payment 
dates to the valuation date (as opposed to the interest rates under 
section 417(e)(3), which the plan uses to determine the amount of the 
benefit).
    Section 1.430(d)-1(f)(4)(iii)(C) provides some alternative 
assumptions that may be used in determining the present value of a 
distribution under Sec.  1.430(d)-1(f)(4)(iii). In the case of a plan 
for which the generational mortality tables are generally used to 
determine present values under section 430(d), Sec.  1.430(d)-
1(f)(4)(iii)(C) allows for the use of a 50-50 male-female blend of the 
annuitant mortality rates under the Sec.  1.430(h)(3)-1(a)(4) 
generational mortality tables in lieu of the applicable mortality table 
under section 417(e)(3).\4\ Section 1.430(d)-1(f)(4)(iii)(C) also 
provides that adjustments to interest rates are permitted to take into 
account the differences between the phase-in of the section 430(h)(2) 
segment rates under section 430(h)(2)(G) and the adjustments to the 
segment rates under section 417(e)(3)(D)(iii).
---------------------------------------------------------------------------

    \4\ The applicable mortality table under section 417(e)(3) is a 
projected static mortality table, based on the mortality table 
specified for the plan year under section 430(h)(3)(A) (without 
regard to section 430(h)(3)(C) or (D)), modified as appropriate by 
the Secretary.
---------------------------------------------------------------------------

    Section 1.430(d)-1(f)(5)(i) provides that, in the case of an 
applicable defined benefit plan described in section 411(a)(13)(C), if 
the amount of a future distribution is based on an interest adjustment 
applied to the current accumulated benefit, then the amount of that 
distribution is determined by projecting the future interest credits or 
equivalent amount under the plan's interest crediting rules using 
actuarial assumptions that satisfy the requirements of Sec.  1.430(d)-
1(f)(3).
    Section 1.430(d)-1(f)(5)(ii)(A) provides that, in the case of an 
applicable defined benefit plan described in section 411(a)(13)(C), if 
the amount of an annuity distribution is based on either the balance of 
a hypothetical account maintained for a participant or the accumulated 
percentage of a participant's final average compensation, then the 
amount of that annuity distribution is calculated by converting the 
projected account balance (or accumulated percentage of final average 
compensation), in accordance with Sec.  1.430(d)-1(f)(5)(i), to an 
annuity by applying the plan's annuity conversion provisions using the 
rules of Sec.  1.430(d)-1(f)(5)(ii).
    Section 1.430(d)-1(f)(5)(ii)(B) provides that generally, if the 
plan bases the conversion of the projected account balance (or 
accumulated percentage of final average compensation) to an annuity 
using the applicable interest rates and applicable mortality table 
under section 417(e)(3), then the amount of the annuity distribution is 
determined by dividing the projected account balance (or accumulated 
percentage of final average compensation) by an annuity factor 
corresponding to the assumed form of payment using, for the period 
beginning with the annuity starting date, the current applicable 
mortality table under section 417(e)(3) that would apply to a 
distribution with an annuity starting date occurring on the valuation 
date (in lieu of the mortality table under section 430(h)(3) that would 
otherwise be used) and the valuation interest rates under section 
430(h)(2) (as opposed to the interest rates under section 417(e)(3) 
which the plan uses to determine the amount of the annuity).
    Section 1.430(d)-1(f)(5)(ii)(C) provides that, in determining the 
amount of an annuity distribution under Sec.  1.430(d)-1(f)(5)(ii)(B), 
a plan is permitted to apply the optional applications of generational 
mortality and phase-in of interest rates described in Sec.  1.430(d)-
1(f)(4)(iii)(C).

Explanation of Provisions

    These proposed regulations would facilitate the adoption of 
amendments that increase benefits. Under these proposed regulations, 
such amendments adopted after the end of the plan year can be taken 
into account in determining the actuarial results for a plan year 
which, in turn, will result in an increased deductible limit for the 
taxable year for the plan sponsor. These proposed regulations would 
also: (1) clarify the plan-related expenses that are includable in 
target normal cost; (2) provide rules for plans that are adopted after 
the end of a plan year; (3) provide rules for when certain plan 
amendments must be taken into account in the actuarial results for a 
plan year; (4) extend the deadline for making certain changes in 
actuarial assumptions or funding methods; and (5) make minor changes to 
the rules for actuarial assumptions to eliminate references to 
statutory provisions that are no longer applicable and to conform them 
to other regulatory provisions.

A. Investment-Related Expenses Not Included in Target Normal Cost

    Proposed Sec.  1.430(d)-1(b)(1)(iii)(B) would provide that plan-
related expenses consist of all amounts that are expected to be paid 
from plan assets that are neither benefits paid to participants and 
beneficiaries (treating the purchase of an annuity as the payment of 
benefits), nor investment-related expenses described in proposed Sec.  
1.430(d)-1(b)(1)(iii)(C).
    Proposed Sec.  1.430(d)-1(b)(1)(iii)(C) would provide that 
investment-related expenses consist of investment manager fees and 
other expenses directly related to the investment of the plan's assets. 
However, if the total payments from plan assets to a service provider 
are expected to be $5,000 or more for a plan year and consist of both 
investment-related expenses and expenses for other services (such as 
recordkeeping services), only those amounts that the service provider 
itemizes as investment management fees or other expenses directly 
related to the investment of the plan's assets are treated as 
investment-related expenses. Amounts itemized as expenses for other 
services are not treated as investment-related expenses.\5\ An example 
of other services would be if the assets of the pension fund are held 
by a bank or trust company affiliated with the fund's investment 
manager and the plan assets are used to pay custodial or trustee fees 
for the safekeeping of the investment assets, such as holding 
securities, settling trades, or collecting income. This exclusion means 
that if the total payments from plan assets to a service provider are 
expected to be less than $5,000, all payments are treated as

[[Page 53808]]

investment-related expenses and the service provider does not need to 
itemize the expenses in order for the plan to exclude these payments 
from target normal cost.
---------------------------------------------------------------------------

    \5\ This $5,000 threshold is consistent with the reporting 
requirement on Form 5500, Schedule C for service providers who have 
rendered services to, or who had transactions with, the plan during 
the reporting year if the service provider received, directly or 
indirectly, $5,000 or more in reportable compensation in connection 
with services rendered or their position with the plan.
---------------------------------------------------------------------------

B. Plans or Plan Amendments That Are Adopted After the End of the Plan 
Year

    Proposed Sec.  1.430(d)-1(d)(1) would provide rules for which plan 
provisions are used to determine a plan's funding target and target 
normal cost for a plan year based on when the plan provisions were 
adopted and, if applicable, what election the plan administrator made. 
For plan provisions adopted by the plan's valuation date, proposed 
Sec.  1.430(d)-1(d)(1)(i) would provide that, except as otherwise 
provided in proposed Sec.  1.430(d)-1(d)(1)(ii) and (iii), a plan's 
funding target and target normal cost for a plan year are determined 
based on plan provisions that are adopted no later than the valuation 
date for the plan year and that take effect on or before the last day 
of the plan year. For example, in the case of a plan amendment adopted 
on or before the valuation date for the current plan year that has an 
effective date occurring in the current plan year, the plan amendment 
is taken into account in determining the funding target and the target 
normal cost for the current plan year if it is permitted to take effect 
under the rules of section 436(c) for the current plan year, but the 
amendment is not taken into account for the current plan year if it 
does not take effect until a future plan year.
    For plan provisions adopted after the plan's valuation date, the 
rules that apply are determined by the election made by the plan 
administrator. Proposed Sec.  1.430(d)-1(d)(1)(ii)(A) would provide 
that if the plan administrator makes an election under section 
412(d)(2) with respect to a plan amendment that is adopted no later 
than 2\1/2\ months after the end of the plan year, then the plan 
amendment will be taken into account in determining the plan's funding 
target and target normal cost for that plan year, provided that the 
plan amendment takes effect no later than the date it is adopted. This 
rule would apply even if the plan amendment were adopted during the 
plan year, consistent with prior revenue rulings.\6\
---------------------------------------------------------------------------

    \6\ See, for example, Rev. Rul. 79-325, 1979-2 C.B. 190.
---------------------------------------------------------------------------

    Proposed Sec.  1.430(d)-1(d)(1)(ii)(B) would provide that if an 
employer adopts a plan after the last day of the employer's taxable 
year and before the due date for the employer's income tax return for 
that taxable year (including extensions) and makes an election under 
the first sentence of section 401(b)(2), then the plan is treated as 
adopted on the last day of that taxable year. In such a case, the 
target normal cost and funding target for the plan's first plan year 
are determined based on the adopted plan provisions, provided that (1) 
the plan takes effect no later than the date the plan is adopted; and 
(2) if the plan's valuation date is before the date the plan is treated 
as being adopted, a section 412(d)(2) election is made.
    Proposed Sec.  1.430(d)-1(d)(1)(ii)(C) would provide that if, 
before the due date (including extensions) for an employer's income tax 
return for a taxable year, the employer adopts an amendment increasing 
benefits accrued under a plan effective as of any date during the plan 
year that immediately precedes the date of adoption, and makes an 
election under section 401(b)(3) with respect to the plan amendment, 
then the plan amendment is treated as having been adopted as of the 
last day of that preceding plan year. In such a case, the target normal 
cost and funding target for that preceding plan year are determined 
taking the plan amendment into account, provided that (1) the amendment 
takes effect no later than the date it is adopted, and (2) if the 
plan's valuation date is before the date the amendment is treated as 
being adopted, a section 412(d)(2) election is made.
    Employers that make an election under either section 401(b)(2) or 
section 401(b)(3) should note that the deadline for minimum required 
contributions under section 430(j)(1) is 8\1/2\ months after the end of 
the plan year, while the deadline for adopting a section 401(b)(2) or 
section 401(b)(3) amendment under either proposed Sec.  1.430(d)-
1(d)(1)(ii)(B) or (C) can be after that deadline, depending on the 
timing of the plan year and the employer's taxable year.

C. Remedial Amendments

    Proposed Sec.  1.430(d)-1(d)(1)(iii) would provide rules under 
which certain planned amendments are taken into account once plan 
operations are changed pursuant to those planned amendments. The 
existing rule in Sec.  1.430(d)-1(d)(1)(iii) would be revised as Sec.  
1.430(d)-1(d)(1)(iv) and is discussed later in part C of this 
Explanation of Provisions. Under proposed Sec.  1.430(d)-
1(d)(1)(iii)(A), if plan operations are changed during a remedial 
amendment period (within the meaning of Sec.  1.401(b)-1(d)) to make 
effective a future remedial amendment, then the provisions of the 
future remedial amendment would be treated as adopted on the date that 
the plan operations are changed. To the extent the actual remedial 
amendment that is adopted is different from the way the plan has been 
operated, the actual remedial amendment is treated as adopted when plan 
operations are changed to reflect the actual remedial amendment (if 
that change in plan operations occurs before the adoption date of the 
amendment). For example, this could happen in the case of a plan that 
is operated in accordance with a statutory change and then plan 
operations are updated to reflect published guidance interpreting that 
statutory change.
    Proposed Sec.  1.430(d)-1(d)(1)(iii)(B) would provide that a plan 
makes effective a future remedial amendment when (1) it is required to 
be amended to address a disqualifying provision that has been 
designated as such by the Commissioner pursuant to Sec.  1.401(b)-
1(b)(3), (2) the remedial amendment period with respect to that 
required amendment has not ended, and (3) plan operations are changed 
in anticipation of a proposed amendment to the plan relating to the 
disqualifying provision.
    Proposed Sec.  1.430(d)-1(d)(1)(iv) would provide substantially the 
same rule as existing Sec.  1.430(d)-1(d)(1)(iii). However, proposed 
Sec.  1.430(d)-1(d)(1)(iv) would not include the existing language 
regarding the effect of an election made under section 412(d)(2), as 
that issue would be separately addressed in proposed Sec.  1.430(d)-
1(d)(1)(ii)(A).

D. Anti-Abuse Rule for Mid-Year Amendments That Increase Target Normal 
Cost Disproportionately

    Proposed Sec.  1.430(d)-1(d)(2)(i) would modify the special rule in 
existing Sec.  1.430(d)-1(d)(2) under which certain plan amendments 
that are not required to be taken into account under the rules of Sec.  
1.430(d)-1(d)(1), because the amendment is adopted after the valuation 
date for the plan year, must nonetheless be taken into account in 
determining a plan's funding target and target normal cost for the plan 
year. A plan amendment would be subject to this rule if it (1) 
increases the liabilities of the plan by reason of increases in current 
benefits, establishment of new benefits, changing the rate of benefit 
accrual, or changing the rate at which benefits become nonforfeitable; 
(2) would not be permitted to take effect under the rules of section 
436 as described in proposed Sec.  1.430(d)-1(d)(2)(ii); and (3) would 
increase the target normal cost disproportionately, as described in 
Sec.  1.430(d)-1(d)(2)(iii).
    Under proposed Sec.  1.430(d)-1(d)(2)(i)(C), the anti-abuse rule in

[[Page 53809]]

Sec.  1.430(d)-1(d)(2) would apply only if the plan amendment increases 
the target normal cost disproportionately. For this purpose, proposed 
Sec.  1.430(d)-1(d)(2)(iii) would provide that a plan amendment 
increases the target normal cost disproportionately if the percentage 
increase in target normal cost as the result of the amendment is more 
than twice the percentage increase in the funding target as a result of 
the amendment (taking into account only the benefits of participants 
currently employed in the service of the employer). Comments are 
requested regarding other appropriate methods of measuring whether a 
plan amendment is considered to increase the target normal cost 
disproportionately, such as by comparing the present value of current 
year accruals with the present value of accruals in succeeding plan 
years.

E. Change in Actuarial Assumptions or Funding Method

    Proposed Sec.  1.430(d)-1(f)(1)(ii) would revise the existing rule 
in Sec.  1.430(d)-1(f)(1)(ii) to address the situation in which an 
application to change actuarial assumptions or funding method has been 
submitted to the Secretary,\7\ but the Secretary has not yet approved 
the application when the assumptions or method are established for the 
plan year. In these situations, the proposed regulations would be 
amended to provide that the assumptions or funding method can be 
changed for that plan year in accordance with the Secretary's approval 
of that application.
---------------------------------------------------------------------------

    \7\ Rev. Proc. 2017-57, 2017-44 I.R.B. 474, sets forth the 
procedure for obtaining approval by the IRS for a change in the 
funding method or actuarial assumptions used for a single-employer 
defined benefit plan.
---------------------------------------------------------------------------

F. Other Rules Regarding Actuarial Assumptions

    Proposed Sec.  1.430(d)-1(f)(4)(iii)(C) would provide rules for 
determining the present value of a distribution under Sec.  1.430(d)-
1(f)(4)(iii) that are substantially the same as a rule in existing 
Sec.  1.430(d)-1(f)(4)(iii)(C). However, the proposed rule would not 
include the existing reference to the phase-in of the section 430(h)(2) 
segment rates that applied under section 430(h)(2)(G) for plan years 
beginning in 2008 or 2009.
    Proposed Sec.  1.430(d)-1(f)(5)(i) and (f)(5)(ii)(A) are 
substantially the same as the corresponding provisions in the existing 
regulations but would make conforming edits to update the terminology 
used in those provisions to conform to the terminology used in Sec.  
1.411(a)(13)-1.
    Proposed Sec.  1.430(d)-1(f)(5)(ii)(C) would provide that the 
option under Sec.  1.430(d)-1(f)(4)(iii)(C) to substitute the 
generational mortality table may be used for purposes of determining 
the amount of an annuity distribution under Sec.  1.430(d)-
1(f)(5)(ii)(B). This provision is substantially the same as existing 
Sec.  1.430(d)-1(f)(5)(ii)(C), except that the heading would be revised 
to reflect that the option to adjust the present values to take into 
account the phase-in of segment rates under section 430(h)(2)(G) is no 
longer applicable.

Proposed Applicability Date

    The regulations are proposed to apply to plan years beginning on or 
after 6 months after the date of publication of the Treasury decision 
adopting these amendments to the regulations as final regulations in 
the Federal Register.

Special Analyses

I. Regulatory Planning and Review--Economic Analysis

    OMB's Office of Information and Regulatory Affairs has determined 
that this proposed rule is not significant and is not subject to review 
under section 6(b) of Executive Order 12866, as amended. This proposed 
rule is expected to be an Executive Order 14192 deregulatory action.

II. Paperwork Reduction Act

    This proposed rulemaking does not impose or revise any information 
collections subject to 44 U.S.C. Chapter 35.

III. Regulatory Flexibility Act

    The Regulatory Flexibility Act requires consideration of the 
regulatory impact on small businesses. It is hereby certified that 
these proposed regulations, if adopted, will not have a significant 
economic impact on a substantial number of small entities within the 
meaning of section 601(6) of the Regulatory Flexibility Act (5 U.S.C. 
chapter 6).
    The economic impact of these regulations is not expected to be 
significant. These regulations are not expected to result in 
economically meaningful changes in behavior. They would update existing 
regulations in order to implement statutory changes enacted after the 
publication of the 2009 regulations. They provide guidance for 
administrators and sponsors of single-employer defined benefit plans 
regarding the determination of target normal cost and the funding 
target.
    For the reasons stated, a regulatory flexibility analysis under the 
Regulatory Flexibility Act is not required. Notwithstanding the above, 
the Treasury Department and the IRS invite comments on the impact the 
proposed rules would have on small entities.
    Pursuant to section 7805(f) of the Code, this notice of proposed 
rulemaking will be submitted to the Chief Counsel for Advocacy of the 
Small Business Administration for comment on its impact on small 
business.

IV. Unfunded Mandates Reform Act

    Section 202 of the Unfunded Mandates Reform Act of 1995 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 in 1995 dollars, updated annually for 
inflation. The proposed 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 (entitled 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. The proposed regulations do not have 
federalism implications, do not impose substantial direct compliance 
costs on State and local governments, and do not preempt State law 
within the meaning of the Executive order.

Comments and Requests for a Public Hearing

    Before these proposed amendments to the final regulations are 
adopted as final regulations, consideration will be given to comments 
that are submitted timely to the IRS as prescribed in this preamble 
under the ADDRESSES heading. The Treasury Department and the IRS 
request comments on all aspects of the proposed regulations. Any 
comments submitted will be made available at https://www.regulations.gov or upon request.
    A public hearing will be scheduled if requested in writing by any 
person who timely submits electronic or written comments. Requests for 
a public hearing are also encouraged to be made electronically. If a 
public hearing is scheduled, notice of the date and time

[[Page 53810]]

for the public hearing will be published in the Federal Register.

Drafting Information

    The principal author of these proposed regulations is Tom Morgan of 
the Office of Associate Chief Counsel (Employee Benefits, Exempt 
Organizations, and Employment Taxes). However, other personnel from the 
Treasury Department and the IRS participated in their development.

List of Subjects in 26 CFR Part 1

    (1) * * *
    (iii) * * *
    (B) Plan-related expenses. For purposes of this paragraph 
(b)(1)(iii), plan-related expenses consist of all amounts that are 
expected to be paid from plan assets that are neither benefits paid to 
participants or beneficiaries (treating the purchase of an annuity 
contract as the payment of benefits) nor investment-related expenses 
described in paragraph (b)(1)(iii)(C) of this section. Plan-related 
expenses include fees paid for professional services (such as legal, 
actuarial, and audit services), plan administration, and premiums paid 
to the Pension Benefit Guaranty Corporation, among other items.
    (C) Investment-related expenses. Investment-related expenses 
consist of investment management fees and other expenses directly 
related to the investment of the plan's assets. However, if the total 
payments from plan assets to a service provider are expected to be 
$5,000 or more for a plan year and consist of investment-related 
expenses and expenses for other services (such as recordkeeping 
services), only those amounts that the service provider itemizes as 
investment management fees or other expenses directly related to the 
investment of the plan's assets are treated as investment-related 
expenses. Amounts itemized as expenses for other services are not 
treated as investment-related expenses.
* * * * *
    (d) Plan provisions taken into account--(1) General rule--(i) Plan 
provisions adopted by valuation date. Except as otherwise provided in 
paragraphs (d)(1)(ii) and (iii), and (d)(2) of this section, a plan's 
funding target and target normal cost for a plan year are determined 
based on plan provisions that are adopted no later than the valuation 
date for the plan year and that take effect on or before the last day 
of the plan year. For example, in the case of a plan amendment adopted 
on or before the valuation date for the current plan year that has an 
effective date occurring in the current plan year, the plan amendment 
is taken into account in determining the funding target and the target 
normal cost for the current plan year if it is permitted to take effect 
under the rules of section 436(c) for the current plan year, but the 
amendment is not taken into account for the current plan year if it 
does not take effect until a future plan year.
    (ii) Plan provisions adopted after valuation date--(A) Impact of 
section 412(d)(2) election. If the plan administrator makes an election 
under section 412(d)(2) with respect to a plan amendment that is 
adopted no later than 2\1/2\ months after the end of a plan year, then 
the amendment will be taken into account in determining the plan's 
funding target and target normal cost for that plan year, provided that 
the amendment takes effect no later than the date the amendment is 
adopted. The preceding sentence applies even if the plan amendment is 
adopted during the plan year.
    (B) Impact of section 401(b)(2) election. If an employer adopts a 
plan after the last day of the employer's taxable year and before the 
due date for the employer's income tax return for that taxable year 
(including extensions) and makes an election under the first sentence 
of section 401(b)(2), then the plan is treated as adopted on the last 
day of that taxable year. In such a case, the target normal cost and 
funding target for the plan's first plan year are determined based on 
the adopted plan provisions, provided that--
    (1) The plan takes effect no later than the date the plan is 
adopted; and
    (2) If the plan's valuation date is before the date the plan is 
treated as being adopted, a section 412(d)(2) election is made.
    (C) Impact of section 401(b)(3) election. If, before the due date 
(including extensions) for an employer's income tax return for a 
taxable year, the employer adopts an amendment increasing benefits 
accrued under a plan effective as of any date during the plan year that 
immediately precedes the date of adoption, and makes an election under 
section 401(b)(3) with respect to the plan amendment, then the plan 
amendment is treated as having been adopted as of the last day of that 
preceding plan year. In such a case, the target normal cost and funding 
target for that preceding plan year are determined taking the plan 
amendment into account, provided that--
    (1) The amendment takes effect no later than the date it is 
adopted; and
    (2) If the plan's valuation date is before the date the amendment 
is treated as being adopted, a section 412(d)(2) election is made.
    (iii) Special rule to reflect plan operations during a remedial 
amendment period--(A) Requirement to reflect future remedial amendment. 
For purposes of this paragraph (d), if plan operations are changed 
during a remedial amendment period (within the meaning of Sec.  
1.401(b)-1(d)) to make effective a future remedial amendment, then the 
provisions of the future remedial amendment are treated as adopted on 
the date that the plan operations are changed. To the extent the 
language of the plan's remedial amendment differs from the way the plan 
was operated at any point during the remedial amendment period, the 
remedial amendment is treated as adopted only when plan operations were 
changed to reflect the language ultimately adopted in that amendment.
    (B) Future remedial amendment. A plan makes effective a future 
remedial amendment when--
    (1) The plan is required to be amended to address a disqualifying 
provision that has been designated as such by the Commissioner pursuant 
to Sec.  1.401(b)-1(b)(3),
    (2) The remedial amendment period with respect to that required 
amendment has not ended, and
    (3) Plan operations are changed in anticipation of a proposed 
amendment

[[Page 53811]]

to the plan relating to the disqualifying provision.
    (iv) Determination of when an amendment takes effect. For purposes 
of this paragraph (d)(1)--
    (A) The determination of whether an amendment that increases 
benefits takes effect and when it takes effect is made in accordance 
with the rules of section 436(c) and Sec.  1.436-1(c)(5); and
    (B) In the case of an amendment that decreases benefits, the 
amendment takes effect under a plan on the first date on which the 
benefits of any individual who is or could be a participant or 
beneficiary under the plan would be less valuable than those benefits 
would be under the pre-amendment plan provisions if the individual were 
on that date to satisfy the applicable conditions for the benefits.
    (2) Special rule for certain amendments increasing liabilities--(i) 
In general. In the case of a plan amendment that takes effect by the 
last day of the plan year but is not required to be taken into account 
under the rules of paragraph (d)(1) of this section because it is 
adopted after the valuation date for the plan year, the plan amendment 
must nonetheless be taken into account in determining a plan's funding 
target and target normal cost for the plan year if the plan amendment--
    (A) Increases the liabilities of the plan by reason of increases in 
current benefits, establishment of new benefits, changing the rate of 
benefit accrual, or changing the rate at which benefits become 
nonforfeitable;
    (B) Would not be permitted under section 436, as described in 
paragraph (d)(2)(ii) of this section; and
    (C) Disproportionately increases target normal cost, as described 
in paragraph (d)(2)(iii) of this section.
    (ii) Plan amendment that would not be permitted under section 436. 
A plan amendment is described in this paragraph (d)(2)(ii) if the plan 
amendment would not be permitted to take effect under the rules of 
section 436(c) as applied under this paragraph (d)(2)(ii). The rules of 
section 436(c) are applied under this paragraph (d)(2)(ii) by--
    (A) Treating the increase in the target normal cost for the plan 
year attributable to the amendment (and all other amendments that must 
be taken into account solely because of the application of the rules in 
this paragraph (d)(2)) as if the increase were an increase in the 
funding target for the plan year; and
    (B) Taking into account all unpredictable contingent event benefits 
permitted to be paid for unpredictable contingent events that occurred 
during the current plan year and all plan amendments that took effect 
in the current plan year (including all amendments to which this 
paragraph (d)(2) applies for the plan year).
    (iii) Plan amendment resulting in disproportionate increase in 
target normal cost. A plan amendment is described in this paragraph 
(d)(2)(iii) if the percentage increase in target normal cost as the 
result of the amendment is more than twice the percentage increase in 
the funding target as a result of the amendment (taking into account 
only the benefits of participants currently employed in the service of 
the employer).
* * * * *
    (f) * * *
    (1) * * *
    (ii) Changes in actuarial assumptions and funding method. Actuarial 
assumptions established for a plan year cannot subsequently be changed 
for that plan year unless the Secretary of the Treasury or the 
Secretary's delegate (Secretary) either approves a request for a change 
in actuarial assumptions that was submitted before the actuarial 
assumptions were established for the plan year or determines that the 
assumptions that were used are unreasonable. Similarly, a funding 
method established for a plan year cannot subsequently be changed for 
that plan year unless the Secretary either approves a request for a 
change in funding method that was submitted before the funding method 
was established for the plan year or determines that the use of that 
funding method for that plan year is impermissible.

    (C) Optional application of generational mortality. In determining 
the present value of a distribution under this paragraph (f)(4)(iii), 
if the generational mortality tables under Sec.  1.430(h)(3)-1(b) or 
Sec.  1.430(h)(3)-2 are used for a plan, then an equal-weighted blend 
of the annuitant mortality rates under the Sec.  1.430(h)(3)-1(b) 
generational mortality tables for males and females may be used in lieu 
of the applicable mortality table under section 417(e)(3) that would 
apply to a distribution with an annuity starting date occurring on the 
valuation date.

    (i) In general. In the case of a statutory hybrid plan described in 
Sec.  1.411(a)(13)-1(d)(5), if the amount of a future distribution is 
based on an interest adjustment applied to the current accumulated 
benefit, then the amount of that distribution is determined by 
projecting the future interest credits or equivalent amount under the 
plan's interest crediting rules using actuarial assumptions that 
satisfy the requirements of paragraph (f)(3) of this section. Thus, if 
a plan provides for a single sum distribution equal to the balance of a 
participant's hypothetical account under a cash balance plan, then the 
amount of that future distribution is equal to the projected account 
balance at the expected date of payment determined using actuarial 
assumptions that satisfy the requirements of paragraph (f)(3) of this 
section.
    (ii) * * *
    (A) General rule. In the case of a statutory hybrid plan with a 
lump sum-based benefit formula as described in Sec.  1.411(a)(13)-
1(d)(3), if the amount of an annuity distribution is based on either 
the balance of the hypothetical account maintained for a participant or 
the accumulated percentage of a participant's final average 
compensation, then the amount of that annuity distribution is 
calculated by converting the projected account balance (or accumulated 
percentage of final average compensation), in accordance with paragraph 
(f)(5)(i) of this section, to an annuity by applying the plan's annuity 
conversion provisions using the rules of this paragraph (f)(5)(ii).
* * * * *
    (C) Optional application of generational mortality. The option 
under paragraph (f)(4)(iii)(C) of this section to substitute the 
generational mortality table may be used for purposes of determining 
the amount of an annuity distribution under paragraph (f)(5)(ii)(B) of 
this section.
* * * * *
    (g) Applicability date. This section applies to plan years 
beginning on or after [DATE SIX MONTHS AFTER DATE OF PUBLICATION OF 
FINAL RULE]. For earlier plan years, taxpayers may apply either the 
rules of this section or the rules described in 26 CFR 1.430(d)-1 (as 
it appeared in the April 1, [2026], edition of 26 CFR part 1).
