    As in the case of earlier reports,\2\ the estimates of tax 
expenditures in this report were prepared in consultation with 
the staff of the Office of Tax Analysis in the Treasury 
Department (``the Treasury''). The Treasury published its 
estimates of tax expenditures for fiscal years 2000-2006 in the 
Administration's budgetary statement of April 2001.\3\ The 
lists of tax expenditures in this Joint Committee staff report 
and the Administration's budgetary statement overlap 
considerably; the differences are discussed in Part I of this 
report under the heading ``Comparisons with Treasury.''

---------------------------------------------------------------------------
    The Joint Committee staff has made its estimates (as shown 
in Table 1) based on the provisions in tax law as enacted 
through December 31, 2001. Expired or repealed provisions are 
not listed unless they have continuing revenue effects that are 
associated with ongoing taxpayer activity. Proposed extensions 
or modifications of expiring provisions are not included until 
they have been enacted into law.
    Part I of this report contains a discussion of the concept 
of tax expenditures. Part II is a discussion of the measurement 
of tax expenditures. Estimates of tax expenditures for fiscal 
years 2002-2006 are presented in Table 1 in Part III. Table 2 
shows the distribution of tax returns by income class, and 
Table 3 presents distributions of selected individual tax 
expenditures by income class.

                   I. THE CONCEPT OF TAX EXPENDITURES

Overview
    ``Tax expenditures'' are defined under the Congressional 
Budget and Impoundment Control Act of 1974 (``the Budget Act'') 
as ``revenue losses attributable to provisions of the Federal 
tax laws which allow a special exclusion, exemption, or 
deduction from gross income or which provide a special credit, 
a preferential rate of tax, or a deferral of tax liability.'' 
\4\ Thus, tax expenditures include any reductions in income tax 
liabilities that result from special tax provisions or 
regulations that provide tax benefits to particular taxpayers.
---------------------------------------------------------------------------
    \4\ Congressional Budget and Impoundment Control Act of 1974 (P.L. 
93-344), sec. 3(3).
---------------------------------------------------------------------------
    Special income tax provisions are referred to as tax 
expenditures because they may be considered to be analogous to 
direct outlay programs, and the two can be considered as 
alternative means of accomplishing similar budget policy 
objectives. Tax expenditures are most similar to those direct 
spending programs that have no spending limits, and that are 
available as entitlements to those who meet the statutory 
criteria established for the programs.\5\
---------------------------------------------------------------------------
    \5\ There are a few tax expenditures that have statutorily imposed 
limits. One example is the tax credit for low-income rental housing. 
This credit is available only to those who have received credit 
allocations from State housing authorities. There are statutory limits 
on the total amounts of credit allocations that the States can make 
each year.
---------------------------------------------------------------------------
    Estimates of tax expenditures are prepared for use in 
budget analysis. They are a measure of the economic benefits 
that are provided through the tax laws to various groups of 
taxpayers and sectors of the economy. The estimates also may be 
useful in determining the relative merits of achieving 
specified public goals through tax benefits or direct outlays.
    The legislative history of the Budget Act indicates that 
tax expenditures are to be defined with reference to a normal 
income tax structure (referred to here as ``normal income tax 
law''). The determination of whether a provision is a tax 
expenditure is made on the basis of a broad concept of income 
that is larger in scope than ``income'' as defined under 
general U.S. income tax principles.\6\ The Joint Committee 
staff has used its judgment in distinguishing between those 
income tax provisions (and regulations) that can be viewed as a 
part of normal income tax law and those special provisions that 
result in tax expenditures. A provision traditionally has been 
listed as a tax expenditure by the Joint Committee staff if 
there is a reasonable basis for such classification and the 
provision results in more than a de minimis revenue loss, which 
solely for this purpose means a total revenue loss of at least 
$50 million over the five fiscal years 2002-2006. The Joint 
Committee staff emphasizes, however, that in the process of 
listing tax expenditures, no judgment is made, nor any 
implication intended, about the desirability of any special tax 
provision as a matter of public policy.
---------------------------------------------------------------------------
    \6\ For this reason, the tax expenditure list in Table 1 includes, 
for example, estimates for the net exclusion of pension contributions 
and earnings, the exclusion of extraterritorial income, as well as 
other exclusions, notwithstanding that such exclusions define income 
under the general rule of U.S. income taxation.
---------------------------------------------------------------------------
    If a tax expenditure provision were eliminated, Congress 
might choose to continue financial assistance through other 
means rather than terminate all Federal assistance for the 
activity. If a replacement spending program were enacted, the 
higher revenues received as a result of the elimination of a 
tax expenditure might not represent a net budget gain. A 
replacement program could involve direct expenditures, direct 
loans or loan guarantees, regulatory activity, a different form 
of tax expenditure, or a general reduction in tax rates. Joint 
Committee staff estimates of tax expenditures do not anticipate 
such policy responses.
    The Budget Act uses the term tax expenditure to refer to 
the special tax provisions that are contained in the Federal 
income taxes on individuals and corporations.\7\ Other Federal 
taxes such as excise taxes, employment taxes, and estate and 
gift taxes may also have exceptions, exclusions, and credits, 
but those special tax provisions are not included in this 
report because they are not part of the income tax. Thus, for 
example, the income tax exclusion for employer-paid health 
insurance is included, but the Federal Insurance Contributions 
Act (``FICA'') tax exclusion for employer-paid health insurance 
is not treated as a tax expenditure.\8\
---------------------------------------------------------------------------
    \7\ The Federal income tax on individuals also applies to estates 
and trusts, which are subject to a separate income tax rate schedule 
(Internal Revenue Code section 1(e)). Estates and trusts may benefit 
from some of the same tax expenditure provisions that apply to 
individuals. In Table 1 of this report, the tax expenditures that apply 
to estates and trusts have been included in the estimates of tax 
expenditures for individual taxpayers.
    \8\ In its budget statement, the Treasury Department identifies tax 
expenditures in the unified transfer tax (the estate and gift tax and 
the generation-skipping transfer tax). See, Office of Management and 
Budget, ``Tax Expenditures,'' April 9, 2001, pp. 91-93. Other analysts 
have explored applying the concept of tax expenditures to the payroll 
and excise taxes. See, Jonathan Barry Forman, ``Would a Social Security 
Tax Expenditure Budget Make Sense?'' Public Budgeting and Financial 
Management, 5, 1993, pp. 311-335, and Bruce F. Davie, ``Tax 
Expenditures in the Federal Excise Tax System,'' National Tax Journal, 
XLVII, March 1994, pp. 39-62.
---------------------------------------------------------------------------
    Some provisions in the Internal Revenue Code provide for 
special tax treatment that is less favorable than normal income 
tax law. Examples of such provisions include (1) the denial of 
deductions for certain lobbying expenses, (2) the denial of 
deductions for certain executive compensation, and (3) the 2-
percent floor on itemized deductions for unreimbursed employee 
expenses. Tax provisions that provide treatment less favorable 
than normal income tax law are not shown in this report because 
they are not included in the statutory definition of a tax 
expenditure.

Individual Income Tax

    Under the Joint Committee staff methodology, the normal 
structure of the individual income tax includes the following 
major components: one personal exemption for each taxpayer and 
one for each dependent, the standard deduction, the existing 
tax rate schedule, and deductions for investment and employee 
business expenses. Most other tax benefits to individual 
taxpayers can be classified as exceptions to normal income tax 
law.
    Personal exemptions and the standard deduction are treated 
as part of normal income tax law because these amounts 
approximate the level of income below which it would be 
difficult for an individual or a family to obtain minimal 
amounts of food, clothing, and shelter. Those itemized 
deductions that are not necessary for the generation of income 
are classified as tax expenditures, but only to the extent that 
they exceed the standard deduction level.
    All employee compensation is subject to tax unless the tax 
code contains a specific exclusion for the income. There are 
specific exclusions for the following employer-provided 
benefits: coverage under accident and health plans,\9\ accident 
and disability insurance, group term life insurance, 
educational assistance, transportation benefits (parking, van 
pools, and transit passes), child care, meals and lodging 
furnished for the convenience of the employer, employee awards, 
and other miscellaneous fringe benefits (e.g., employee 
discounts, services provided to employees at no additional cost 
to employers, tuition reductions, and de minimis fringe 
benefits). Each of these exclusions is classified as a tax 
expenditure in this report.
---------------------------------------------------------------------------
    \9\ Present law contains an exclusion for employer-provided 
coverage under accident and health plans (sec. 106 of the Internal 
Revenue Code of 1986, the ``Code'') and an exclusion for benefits 
received by employees under employer-provided accident and health plans 
(Code sec. 105(b)). These two exclusions are viewed as a single tax 
expenditure. Under normal income tax law, the value of employer-
provided accident and health coverage would be includable in the income 
of employees, but employees would not be subject to tax on the accident 
and health insurance benefits (reimbursements) that they might receive.
---------------------------------------------------------------------------
    Under normal income tax law, employer contributions to 
pension plans and income earned on pension assets would be 
taxable to employees as the contributions are made and as the 
income is earned, and employees would not receive any deduction 
or exclusion for their pension contributions. Under present 
law, employer contributions to qualified pension plans and 
employee contributions made at the election of the employee 
through salary reduction are not taxed until distributed to the 
employee, and income earned on pension assets is not taxed 
until distributed. The tax expenditure for ``net exclusion of 
pension contributions and earnings'' is computed as the income 
taxes forgone on current tax-excluded pension contributions and 
earnings less the income taxes paid on current pension 
distributions (including the 10-percent additional tax paid on 
early withdrawals from pension plans).
    Under present law, social security and tier 1 railroad 
retirement benefits are fully or partially excluded from gross 
income.\10\ Under normal income tax law, retirees would be 
entitled to an exclusion for only the portion of the retirement 
benefits that represents a return of the payroll taxes that 
they paid during their working years. Thus, the exclusion of 
social security and raiload retirement benefits in excess of 
payroll tax payments is classified as a tax expenditure.
---------------------------------------------------------------------------
    \10\ For taxpayers with modified adjusted gross incomes above 
certain levels, up to 85 percent of social security retirement benefits 
are includable in income.
---------------------------------------------------------------------------
    All Medicare benefits are excluded from taxation. The value 
of Medicare Part A insurance generally is greater than the 
Health Insurance (``HI'') tax contributions that enrollees made 
during their working years, and the value of Medicare Part B 
insurance generally is greater than the Part B premium that 
enrollees must pay. The exclusion of the value of Medicare Part 
A insurance in excess of HI tax contributions is classified as 
a tax expenditure, and the exclusion of the value of Medicare 
Part B insurance in excess of premiums paid also is classified 
as a tax expenditure.
    Public assistance benefits are excluded from gross income 
by statute or by Internal Revenue Service regulations. Table 1 
contains tax expenditure estimates for workers' compensation 
benefits, special benefits for disabled coal miners, and cash 
public assistance benefits (which include Supplemental Security 
Income benefits and Temporary Assistance for Needy Families 
benefits).
    The individual income tax does not include in gross income 
the imputed income that individuals receive from the services 
provided by owner-occupied homes and durable goods.\11\ 
However, the Joint Committee staff does not classify this 
exclusion as a tax expenditure. The measurement of imputed 
income for tax purposes presents administrative problems and 
its exclusion from taxable income may be regarded as an 
administrative necessity.\12\
---------------------------------------------------------------------------
    \11\ The National Income and Product Accounts include estimates of 
this imputed income. The accounts appear in U.S. Department of 
Commerce, Bureau of Economic Analysis, Survey of Current Business, 
published monthly.
    \12\ If the imputed income from owner-occupied homes were included 
in adjusted gross income, it would be proper to include all mortgage 
interest deductions and related property tax deductions as part of the 
normal income tax structure, since interest and property tax deductions 
would be allowable as a cost of producing imputed income. It also would 
be appropriate to allow deductions for depreciation and maintenance 
expenses for owner-occupied homes.
---------------------------------------------------------------------------
    Under normal income tax law, individuals would be allowed 
to deduct only the interest on indebtedness incurred in 
connection with a trade or business or an investment. Thus, the 
deduction for mortgage interest on a principal or second 
residence is classified as a tax expenditure.
    The Joint Committee staff assumes that, for administrative 
feasibility, normal income tax law would tax capital gains in 
full in the year the gains are realized through sale or 
exchange. Thus, the deferral of tax until realization is not 
classified as a tax expenditure, but reduced rates of tax, 
further deferrals of tax (beyond the year of sale or exchange), 
and exclusions of certain capital gains are classified as tax 
expenditures.
    It also is assumed that normal income tax law would not 
provide for any indexing of the basis of capital assets for 
changes in the general price level. Thus, under normal income 
tax law (as under present law), the income tax would be levied 
on nominal gains as opposed to real gains in asset values. If, 
as an alternative, normal income tax law were defined to 
include full indexing of the basis of capital assets, the 
capital gains tax expenditure estimates in Table 1 generally 
would be lower than those shown.
    There are many types of State and local government bonds 
and private purpose bonds that qualify for tax-exempt status 
for Federal income tax purposes. Table 1 contains a separate 
tax expenditure listing for each type of bond.
    Under the Joint Committee staff view of normal tax law, 
compensatory stock options would be subject to regular income 
tax at the time the options are exercised and employers would 
receive a corresponding tax deduction.\13\ The employee's 
income would be equal to the difference between the purchase 
price of the stock and the market price on the day the option 
is exercised. Present law provides for special tax treatment 
for incentive stock options and options acquired under employee 
stock purchase plans. When certain requirements are satisfied, 
(1) the income that is received at the time the option is 
exercised is excluded for purposes of the regular income tax 
but included for purposes of the alternative minimum tax, (2) 
the gain from any subsequent sale of the stock is taxed as a 
capital gain, and (3) the employer does not receive a tax 
deduction with respect to the option. The special tax treatment 
provided to the employee is viewed as a tax expenditure by the 
Joint Committee staff, and an estimate of this tax expenditure 
is contained in Table 1. However, it should be noted that the 
revenue loss from the special tax treatment provided to the 
employee is accompanied by a significant revenue gain from the 
denial of the deduction to the employer.
---------------------------------------------------------------------------
    \13\ If the option has a readily ascertainable fair market value, 
normal law would tax the option at the time it is granted and the 
employer would be entitled to a deduction at that time.
---------------------------------------------------------------------------
    The individual alternative minimum tax (``AMT'') and the 
passive activity loss rules are not viewed by the Joint 
Committee staff as a part of normal income tax law. Instead, 
they are viewed as provisions that reduce the magnitude of the 
tax expenditures to which they apply. For example, the AMT 
reduces the value of the deduction for State and local income 
taxes (for those taxpayers subject to the AMT) by not allowing 
the deductions to be claimed in the calculation of AMT 
liability. Similarly, the passive loss rules defer otherwise 
allowable deductions and credits from passive activities until 
a time when the taxpayer has passive income or disposes of the 
assets associated with the passive activity. Exceptions to the 
individual AMT and the passive loss rules are not classified as 
tax expenditures by the Joint Committee staff because the 
effects of the exceptions already are incorporated in the 
estimates of related tax expenditures.

Business Income Taxation

    Regardless of the legal form of organization (sole 
proprietorship, partnership, or S or C corporation), the same 
general principles are used in the computation of taxable 
business income. Thus, most business tax expenditures apply 
equally to unincorporated and incorporated businesses.
    One of the most difficult issues in defining tax 
expenditures for business income relates to the tax treatment 
of capital costs. Under present law, capital costs may be 
recovered under a variety of alternative methods, depending 
upon the nature of the costs and the status of the taxpayer. 
For example, investments in equipment and structures may 
qualify for tax credits, expensing, accelerated depreciation, 
or straight-line depreciation. The Joint Committee staff 
generally classifies as tax expenditures cost recovery 
allowances that are more favorable than those provided under 
the alternative depreciation system (sec. 168(g)), which 
provides for straight-line recovery over tax lives that are 
longer than those permitted under the accelerated system.
    As indicated above, the Joint Committee staff assumes that 
normal income tax law would not provide for any indexing of the 
basis of capital assets. Thus, normal income tax law would not 
take into account the effects of inflation on tax depreciation. 
The expensing and depreciation tax expenditure estimates in 
Table 1 are larger than would be the case if normal income tax 
law provided for inflation adjustments in the basis of assets 
for tax depreciation purposes.
    The Joint Committee staff uses several accounting standards 
in evaluating the provisions in the Code that govern the 
recognition of business receipts and expenses. Under the Joint 
Committee staff view, normal income tax law is assumed to 
require the accrual method of accounting, the standard of 
``economic performance'' (used in the Code to test whether 
liabilities are deductible), and the general concept of 
matching income and expenses. In general, tax provisions that 
do not satisfy all three standards are viewed as tax 
expenditures. For example, the deduction for contributions to 
taxpayer-controlled mining reclamation reserve accounts is 
viewed as a tax expenditure because the contributions do not 
satisfy the economic performance standard. (Adherence to the 
standard would require that the taxpayer make an irrevocable 
contribution toward future reclamation, involving a trust fund 
or similar mechanism, as occurs in a number of areas in the 
Code.) The deduction for contributions to nuclear 
decommissioning trust accounts is not viewed as a tax 
expenditure because the contributions are irrevocable (i.e., 
they satisfy the economic performance standard). However, 
present law provides for a reduced rate of tax on the income of 
nuclear decommissioning trust accounts, and this reduced rate 
of tax is viewed as a tax expenditure.

Corporate Income Tax

    The income of corporations (other than S corporations) 
generally is subject to the corporate income tax. The corporate 
income tax includes a graduated tax rate schedule. The lower 
tax rates in the schedule are classified by the Joint Committee 
staff as a tax expenditure (as opposed to normal income tax 
law) because they are intended to provide tax benefits to small 
business and, unlike the graduated individual income tax rates, 
are unrelated to concerns about ability of individuals to pay 
taxes.
    Exceptions to the corporate alternative minimum tax are not 
viewed as tax expenditures because the effects of the AMT 
exceptions are already incorporated in the estimates of related 
tax expenditures.\14\
---------------------------------------------------------------------------
    \14\ See discussion of individual AMT on page 6.
---------------------------------------------------------------------------
    Certain income of pass-through entities is exempt from the 
corporate income tax. The income of sole proprietorships, S 
corporations, and most partnerships is taxed only at the 
individual level. The special tax rules for these pass-through 
entities are not classified as tax expenditures because the tax 
benefits are available to any entity that chooses to organize 
itself and operate in the required manner.
    Nonprofit corporations that satisfy the requirements of 
Code section 501 also generally are exempt from corporate 
income tax. The tax exemption of certain nonprofit cooperative 
business organizations, such as trade associations, is not 
treated as a tax expenditure for the same reason applicable to 
for-profit pass-through business entities. With respect to 
other nonprofit organizations, such as charities, tax-exempt 
status is not classified as a tax expenditure because the 
nonbusiness activities of such organizations generally must 
predominate and their unrelated business activities are subject 
to tax. In general, the imputed income derived from nonbusiness 
activities conducted by individuals or collectively by certain 
nonprofit organizations is outside the normal income tax base. 
However, the ability of donors to such nonprofit organizations 
to claim a charitable contribution deduction is a tax 
expenditure (because such contributions do not generate income 
to the donor), as is the exclusion of income granted to holders 
of tax-exempt financing issued by charities.

Recent Legislation

    The Fallen Hero Survivor Benefit Fairness Act of 2001 (H.R. 
1727), enacted on June 5, 2001 (P.L. 107-15), broadened the 
exclusion for survivor annuities paid on account of the death 
of public safety officers killed in the line of duty. Under 
prior law, the exclusion was effective for annuities with 
respect to public safety officers dying after December 31, 
1996. The Act extended the exclusion to annuities with respect 
to officers dying prior to January 1, 1997, effective for 
payments received after December 31, 2001.
    The Economic Growth and Tax Relief Reconciliation Act of 
2001 (H.R. 1836), enacted on June 7, 2001 (P.L. 107-16), 
modified a number of tax expenditures, as follows:
    --The child tax credit was increased to $600 per child in 
2001 through 2004, $700 per child in 2005 through 2008, $800 
per child in 2009, and $1,000 per child in 2010 and thereafter. 
In addition, the child credit was made refundable to the extent 
of 10 percent of the taxpayer's earned income in excess of 
$10,000 for calendar years 2001-2004 (and 15 percent after 
2004), and the refundable portion of the credit is no longer 
reduced by the amount of the alternative minimum tax, effective 
for taxable years beginning after December 31, 2000.
    --The adoption tax credit for children other than special 
needs children, which was scheduled to expire for expenses paid 
or incurred after December 31, 2001, was permanently extended 
and the maximum credit for such adoptions was increased to 
$10,000 per child. The maximum credit for taxpayers adopting 
special needs children was also increased to $10,000. The 
income phase-out range for the adoption credit was increased 
and the credit is now allowed against the alternative minimum 
tax. All of these provisions are effective for taxable years 
beginning after December 31, 2001. In taxable years beginning 
after December 31, 2002, a $10,000 credit for the adoption of 
special needs children will be provided in the year the 
adoption is finalized regardless of whether the taxpayer has 
adoption expenses.
    --The exclusion for employer-provided adoption assistance, 
which was scheduled to expire for amounts paid or incurred 
after December 31, 2001, was permanently extended. The maximum 
exclusion was increased to $10,000 per child and the income 
phase-out range for the exclusion was also increased, both 
effective for taxable years beginning after December 31, 2001. 
In taxable years beginning after December 31, 2002, a $10,000 
exclusion for the adoption of special needs children will be 
provided in the year the adoption is finalized regardless of 
whether the taxpayer has adoption expenses.
    --The dependent care tax credit was modified in several 
ways. The maximum amount of eligible employment-related 
expenses was increased from $2,400 to $3,000 for one qualifying 
individual and from $4,800 to $6,000 for two or more qualifying 
individuals, the maximum credit was increased from 30 percent 
to 35 percent of eligible expenses, and the beginning point for 
the phase-down of the credit was increased from $10,000 to 
$15,000 of adjusted gross income. All of these changes are 
effective for taxable years beginning after December 31, 2002.
    --A number of changes were made to the earned income 
credit: (1) for married taxpayers, the phase-out ranges were 
modified, (2) the definition of earned income was simplified by 
excluding nontaxable employee compensation, (3) the provision 
that reduces the earned income credit by the amount of a 
taxpayer's alternative minimum tax was repealed, (4) the 
definition of a qualifying child was simplified, and (5) the 
calculation of the credit was simplified by replacing modified 
adjusted gross income with adjusted gross income. These changes 
are effective for taxable years beginning after December 31, 
2001.
    --The following changes were made to Coverdell education 
savings accounts \15\ (``Coverdell accounts''): (1) the annual 
limit on contributions was increased from $500 to $2,000, (2) 
the definition of qualified education expenses was expanded to 
include elementary and secondary school expenses, (3) the 
income phase-out range for married taxpayers filing joint 
returns was increased so that it is twice the range for single 
taxpayers, (4) the various age limitations no longer apply to 
special needs beneficiaries, (5) corporations and other 
entities now are permitted to make contributions to Coverdell 
accounts regardless of the income of the corporation or entity, 
(6) taxpayers may claim a HOPE credit or Lifetime Learning 
credit and, in the same taxable year, exclude from gross income 
amounts distributed from Coverdell accounts on behalf of the 
same student, provided that the distribution is not used for 
the same education expenses for which a credit was claimed, and 
(7) there is no longer an excise tax on contributions made to 
Coverdell accounts during a taxable year in which contributions 
are made to a qualified State tuition program on behalf of the 
same beneficiary. All of these changes are effective for 
taxable years beginning after December 31, 2001.
---------------------------------------------------------------------------
    \15\ These accounts were previously referred to as ``education 
IRAs'' but were renamed by S. 1190, enacted on July 26, 2001 (P.L. 107-
22).
---------------------------------------------------------------------------
    --The rules governing the tax-exempt status of prepaid 
tuition programs were modified as follows: (1) the definition 
of ``qualified tuition program'' was expanded to include 
programs maintained by certain private educational 
institutions, (2) the definition of qualified higher education 
expenses was modified to include certain expenses of special 
needs beneficiaries, (3) an exclusion from gross income was 
provided for distributions from qualified tuition programs that 
are used for qualified higher education expenses, (4) taxpayers 
may claim a HOPE credit or Lifetime Learning credit and, in the 
same taxable year, exclude from gross income amounts 
distributed from a qualified tuition program on behalf of the 
same student, provided that the distribution is not used for 
the same education expenses for which a credit was claimed. (5) 
a transfer of credits from one qualified tuition program to 
another program for the same beneficiary will no longer be 
considered a taxable distribution, and (6) the present-law 
penalty on tuition program distributions not used for higher 
education expenses is replaced by the same tax that now applies 
to distributions from Coverdell accounts that are not used for 
higher education expenses. These provisions are effective for 
taxable years beginning after December 31, 2001, except that 
the exclusion from gross income for distributions from tuition 
programs maintained by private educational institutions is 
effective for taxable years beginning after December 31, 2003.
    --The exclusion for employer-provided educational 
assistance for undergraduate courses, which was scheduled to 
expire for courses beginning after December 31, 2001, was 
permanently extended and the exclusion was broadened to include 
graduate courses, effective for graduate courses beginning 
after December 31, 2001.
    --Several changes were made to the deduction for interest 
on student loans: (1) the income phase-out ranges for the 
deduction were increased, (2) the limit on the number of months 
during which interest payments are deductible was repealed, and 
(3) the restriction that voluntary payments of interest are not 
deductible was repealed. These changes are effective for 
interest paid after December 31, 2001.
    --The exclusion for scholarship and fellowship income was 
broadened to include awards under the National Health Service 
Corps Scholarship Program and the F. Edward Hebert Armed Forces 
Health Professions Scholarship and Financial Assistance 
Program, thus providing an exception to the general rule that 
the exclusion does not apply to amounts representing payment 
for services that are required of the student. The exclusion 
for awards under these two programs is effective for amounts 
received after December 31, 2001. The exclusion does not apply 
to amounts received by students for regular living expenses, 
including room and board.
    --The additional amount of governmental bonds for public 
schools that small governmental units may issue without being 
subject to the arbitrage rebate requirements was increased from 
$5 million to $10 million. In addition, the list of private 
activities for which tax-exempt bonds may be issued was 
expanded to include elementary and secondary public school 
facilities which are owned by private for-profit corporations 
pursuant to public-private partnership agreements with State or 
local agencies. These provisions are effective for bonds issued 
after December 31, 2001.
    --Numerous changes were made in the rules relating to 
individual retirement arrangements (``IRAs'') and qualified 
pension plans. Some of the changes include: (1) increased 
contribution limits and catch-up contributions for IRAs; (2) 
provisions for expanding pension plan coverage, including 
increased contribution and benefit limits for qualified plans, 
(3) provisions to enhance IRA and pension plan fairness for 
women, including additional catch-up contributions for 
individuals over age 50, and (4) provisions for increasing 
portability for plan participants. These provisions are 
generally effective for taxable years beginning after December 
31, 2001.
    The Economic Growth and Tax Relief Reconciliation Act also 
created five new tax expenditures:
    --The Act provided a new above-the-line deduction for 
qualified higher education expenses. In 2002 and 2003, the 
maximum deduction is $3,000 and the deduction is available only 
to taxpayers with adjusted gross income (``AGI'') that is equal 
to or less than $65,000 ($130,000 for joint returns). In 2004 
and 2005, a maximum deduction of $4,000 is available to 
taxpayers with AGI equal to or less than $65,000 ($130,000 for 
joint returns), and a maximum deduction of $2,000 is available 
to taxpayers with AGI of more than $65,000 ($130,000 for joint 
returns) but no more than $80,000 ($160,000 for joint returns). 
The deduction is effective for taxable years beginning after 
December 31, 2001, but does not apply to taxable years 
beginning after December 31, 2005.
    --The Act provided a new tax credit for employers who 
provide child care for employees. The credit is equal to 25 
percent of expenditures on child care plus 10 percent of 
expenditures on child care resource and referral services. The 
credit is effective for taxable years beginning after December 
31, 2001.
    --The Act provided a new exclusion for certain restitution 
payments made to eligible individuals (and the heirs and 
estates of such individuals) who were persecuted for racial or 
religious reasons by Nazi Germany or other Axis regimes. The 
exclusion is effective for amounts received on or after January 
1, 2000. This tax expenditure is not listed in Table 1 because 
the estimated revenue loss is below the de minimis amount.
    --The Act provided a temporary nonrefundable tax credit for 
up to $2,000 of elective contributions to qualified pension 
plans and IRAs. The rate of the credit is based on the 
taxpayer's adjusted gross income. The credit is effective for 
taxable years beginning after December 31, 2001, and before 
January 1, 2007.
    --The Act provided a nonrefundable income tax credit for 
the administrative and retirement-education expenses for new 
pension plans adopted by small businesses. The credit is equal 
to 50 percent of the first $1,000 in expenses for each of the 
first three years of the new plan. The credit is effective with 
respect to costs paid or incurred in taxable years beginning 
after December 31, 2001, with respect to plans established 
after that date.
    The Railroad Retirement and Survivors' Improvement Act of 
2001 (H.R. 10), enacted on December 21, 2001 (P.L 107-90), 
creates the National Railroad Retirement Trust, transfers 
certain funds to the trust, and amends Code sec. 501(c) to 
include the trust in the list of tax exempt organizations. The 
tax exemption for 501(c) organizations is not viewed as a tax 
expenditure for the reasons explained earlier.\16\
---------------------------------------------------------------------------
    \16\ See discussion on page 7.
---------------------------------------------------------------------------
    The Victims of Terrorism Tax Relief Act of 2001 (H.R. 2884) 
was passed by the House of Representatives and the Senate on 
December 20, 2001. Upon enactment, this bill will provide 
certain tax benefits to the victims of the terrorist attacks 
that occurred on April 19, 1995, and September 11, 2001. Some 
of the tax provisions in this bill could be viewed as tax 
expenditures but none are listed in Table 1 because the 
estimated revenue losses for fiscal years 2002 through 2006 are 
below the de minimis amount ($50 million).

Expiring Provisions

    The tax credit for electricity production from wind, 
closed-loop biomass, and poultry waste expired for facilities 
placed in service after December 31, 2001. The tax expenditure 
estimate in Table 1 is based on the credits that will be earned 
from electricity produced from facilities placed in service 
prior to January 1, 2002.
    The work opportunity tax credit expired for employees hired 
after December 31, 2001. The tax expenditure estimate in Table 
1 is based on credits that will be earned for workers hired 
prior to January 1, 2002.
    The welfare-to-work tax credit expired for employees hired 
after December 31, 2001. The tax expenditure estimate in Table 
1 is based on credits that will be earned for workers hired 
prior to January 1, 2002.
    Qualified zone academy bonds were authorized to be issued 
in 2001 and earlier calendar years. No additional 
authorizations have been enacted for calendar years 2002 and 
thereafter. The tax expenditure estimate in Table 1 is based on 
bonds issued prior to 2002 and bonds that will be issued in 
2002 and thereafter using the remaining bond authority from 
calendar years 2001 and earlier.

Comparisons With Treasury Department

    The Joint Committee staff and Treasury lists of tax 
expenditures differ in three respects. First, the Treasury uses 
a different classification of those provisions that can be 
considered a part of normal income tax law under both the 
individual and business income taxes. In general, the Joint 
Committee staff methodology involves a narrower concept of 
normal income tax law. Thus, the Joint Committee list of tax 
expenditures includes some provisions that are not contained in 
the Treasury list. The cash method of accounting provides an 
example. The Treasury considers the cash accounting option for 
certain businesses to be a part of normal income tax law, but 
the Joint Committee staff methodology treats it as a departure 
from normal income tax law that constitutes a tax expenditure.
    Second, the Joint Committee staff and Treasury estimates of 
tax expenditures span slightly different sets of years. The 
Treasury's estimates cover a seven-year period--the last fiscal 
year, the current fiscal year when the President's budget is 
submitted, and the next five fiscal years, i.e., fiscal years 
2000-2006. The Joint Committee staff estimates cover the 
current fiscal year and the succeeding four fiscal years, i.e., 
fiscal years 2002-2006.
    Third, the Joint Committee staff list excludes those 
provisions that are estimated to result in revenue losses below 
the de minimis amount, i.e., less than $50 million over the 
five fiscal years 2002 through 2006. The Treasury rounds all 
yearly estimates to the nearest $10 million and excludes those 
provisions with estimates that round to zero in each year, 
i.e., provisions that result in less than $5 million in revenue 
loss in each of the years 2000 through 2006.
    For the past nine years, the President's budget has 
contained a section that reviews and tabulates the estate and 
gift tax provisions that the Treasury considers as tax 
expenditures. The Joint Committee staff considers estate and 
gift tax provisions as being outside of the normal income tax 
structure and thus omits them from its list of tax 
expenditures.
    In some cases, two or more of the tax expenditure items in 
the Treasury list have been combined into a single item in the 
Joint Committee staff list, and vice versa. The Table 1 
descriptions of some tax expenditures also may vary from the 
descriptions used by the Treasury.
    The following is a list of tax provisions that are 
contained in the Joint Committee staff list of tax expenditures 
(and are shown in Table 1) but are not contained in the 
Treasury list:

Natural resources and environment

--Exclusion of contributions in aid of construction for water 
            and sewer utilities
--Special rules for mining reclamation reserves
--Special tax rate for nuclear decommissioning reserve funds

Agriculture

--Exclusion of cost-sharing payments
--Cash accounting for agriculture
--Five-year carryback period for net operating losses 
            attributable to farming

Insurance companies

--Special treatment of life insurance company reserves
--Deduction of unpaid loss reserves of property and casualty 
            companies

Business and commerce

--Expensing of magazine circulation expenditures
--Special rules for magazine, paperback book, and record 
            returns
--Completed contract rules
--Cash accounting, other than agriculture
--Deferral of gain on like-kind exchanges
--Exception from net operating loss limitations for 
            corporations in bankruptcy
--Tax credit for employer-paid FICA taxes on tips
--Deferral of gain on involuntary conversions resulting from 
            Presidentially-declared disasters

Employment

--Exclusion of miscellaneous fringe benefits
--Exclusion of employee awards
--Exclusion of income earned by voluntary employee beneficiary 
            associations
--Exclusion of spread on acquisition of stock under incentive 
            stock option plans and employee stock purchase 
            plans

Medicare

--Exclusion of untaxed Medicare benefits for Hospital Insurance
--Exclusion of untaxed Medicare benefits for Supplementary 
            Medical Insurance

    The following tax provisions are not included in the Joint 
Committee staff list of tax expenditures or the Treasury list. 
However, these provisions are viewed as tax expenditures by the 
Joint Committee staff. These provisions are not listed in Table 
1 because the estimated revenue losses for fiscal years 2002 
through 2006 are below the de minimis amount ($50 million):

Energy

--Expensing of tertiary injectants

Financial institutions

--Exclusion of investment income from structured settlement 
            arrangements

Income security

--Exclusion of survivor annuities paid to families of public 
            safety officers killed in the line of duty

    The following is a list of the tax provisions that are 
included in the Treasury list and are viewed as tax 
expenditures by the Joint Committee staff but are excluded from 
Table 1 because the estimated revenue losses for fiscal years 
2002 through 2006 are below the de minimis amount ($50 
million):

Energy

--Tax credit for electric vehicles
--Deductions for clean-fuel vehicles and refueling property

Natural resources and environment

--Tax credit and seven-year amortization for reforestation 
            expenditures

Agriculture

--Deferral of tax on gains from the sale of stock in a 
            qualified refiner or processor to an eligible 
            farmer's cooperative

Financial institutions

--Bad debt reserves of financial institutions

Insurance companies

--Special alternative tax on small property and casualty 
            insurance companies
--Tax exemption for certain small insurance companies

Business and commerce

--Exclusion of income from discharge of indebtedness incurred 
            in connection with qualified real property

Social services

--Expensing of costs for removing architectural barriers

    There are three additional tax expenditure provisions in 
the Treasury list that are not included in the Joint Committee 
staff list. Two of the provisions involve exceptions to the 
passive loss rules: the exception for working interests in oil 
and gas properties, and the exception for up to $25,000 of 
rental losses. The Joint Committee staff does not classify 
these two provisions as tax expenditures; the effects of the 
passive loss rules (and exceptions to the rules) are included 
in the estimates of the tax expenditure provisions that are 
affected by the rules.\17\ The third tax expenditure in the 
Treasury list that is not included in the Joint Committee staff 
list is the exemption of certain income of telephone and 
electric cooperatives. The Joint Committee staff does not 
classify this provision as a tax expenditure because the 
special tax rules for pass-through entities are assumed to be a 
part of normal tax law.\18\

rules, above on page 6.

                  II. MEASUREMENT OF TAX EXPENDITURES

Tax Expenditure Estimates Generally
    A tax expenditure is measured by the difference between tax 
liability under present law and the tax liability that would 
result from a recomputation of tax without benefit of the tax 
expenditure provision. Taxpayer behavior is assumed to remain 
unchanged for tax expenditure estimate purposes.\19\
---------------------------------------------------------------------------
    \19\ An alternative way to measure tax expenditures is to express 
their values in terms of ``outlay equivalents.'' An outlay equivalent 
is the dollar size of a direct spending program that would provide 
taxpayers with net benefits that would equal what they now receive from 
a tax expenditure. The Treasury Department presents estimates of outlay 
equivalents in the President's budget in addition to presenting 
estimates in the same manner as the Joint Committee staff.
---------------------------------------------------------------------------
    The tax expenditure estimates in this report are based on 
Congressional Budget Office and Joint Committee staff 
projections of the gross income, deductions, and expenditures 
of individuals and corporations for calendar years 2001-2006. 
These projections are used to compute tax liabilities for the 
present-law revenue baseline and tax liabilities for the 
alternative baseline that assumes that the tax expenditure 
provision does not exist.
    Internal Revenue Service (``IRS'') statistics from recent 
tax returns are used to develop projections of the tax credits, 
deductions, and exclusions that will be claimed under the 
present-law baseline. These IRS statistics show the actual 
usage of the various tax expenditure provisions. In the case of 
some tax expenditures, such as the earned income credit, there 
is evidence that some taxpayers are not claiming all of the 
benefits to which they are entitled, while others are filing 
claims that exceed their entitlements. The tax expenditure 
estimates in this report are based on projections of actual 
claims under the various tax provisions, not the tax benefits 
to which taxpayers are entitled.
    Some tax expenditure estimates are based partly on 
statistics for income, deductions, and expenses for prior 
years. Accelerated depreciation is an example. Estimates for 
this tax expenditure are based on the difference between tax 
depreciation deductions under present law and the deductions 
that would have been claimed in the current year if investments 
in the current year and all prior years had been depreciated 
using the alternative (normal income tax law) depreciation 
system.
    Each tax expenditure is estimated separately, under the 
assumption that all other tax expenditures remain in the tax 
code. If two or more tax expenditures were estimated 
simultaneously, the total change in tax liability could be 
smaller or larger than the sum of the amounts shown for each 
item separately, as a result of interactions among the tax 
expenditure provisions.
    Year-to-year differences in the estimates for each tax 
expenditure reflect changes in tax law, including phaseouts of 
tax expenditure provisions and changes that alter the 
definition of the normal income tax structure, such as the tax 
rate schedule, the personal exemption amount, and the standard 
deduction. Some of the estimates for this tax expenditure 
report may differ from estimates made in previous years because 
of changes in law and economic conditions, the availability of 
better data, and improved estimating techniques.
Tax Expenditures versus Revenue Estimates
    A tax expenditure estimate is not the same as a revenue 
estimate for the repeal of the tax expenditure provision for 
three reasons. First, tax expenditure estimates do not 
incorporate any changes in taxpayer behavior, whereas revenue 
estimates incorporate the effects of the behavioral changes 
that are anticipated to occur in response to the repeal of a 
tax provision. Second, tax expenditure estimates are concerned 
with changes in the tax liabilities of taxpayers. Because the 
tax expenditure focus is on tax liabilities as opposed to 
Federal government tax receipts, there is no concern for the 
timing of tax payments. Revenue estimates are concerned with 
changes in Federal tax receipts which are affected by the 
timing of tax payments. Third, some of the tax provisions that 
provide an exclusion from income also apply to the FICA tax 
base, and the repeal of the income tax provision would 
automatically increase FICA tax revenues as well as income tax 
revenues.
    If a tax expenditure provision were repealed, it is likely 
that the repeal would be made effective at the beginning of a 
calendar year. In this case, the revenue estimate for repeal 
would show a smaller revenue gain in the first fiscal year than 
in subsequent years, because the repeal would be occurring 
after the start of the government's fiscal year. The revenue 
estimate might also reflect some delay in the timing of the 
revenue gains as a result of the taxpayer tendency to postpone 
or forgo changes in tax withholding and estimated tax payments.

                     III. TAX EXPENDITURE ESTIMATES

    Tax expenditures are grouped in Table 1 in the same 
functional categories as outlays in the Federal budget. 
Estimates are shown separately for individuals and 
corporations. Those tax expenditures that do not fit clearly 
into any single budget category have been placed in the most 
appropriate category.
    Several of the tax expenditure items involve small amounts 
of revenue, and those estimates are indicated in Table 1 by 
footnote 1. For each of these items, the footnote means that 
the tax expenditure is less than $50 million in the fiscal 
year.
    Table 2 presents tax return information for each of nine 
income classes on the number of all returns (including filing 
and nonfiling units), the number of taxable returns, the number 
of returns with itemized deductions, and the amount of tax 
liability.
    Table 3 provides distributional estimates by income class 
for some of the tax expenditures that affect individual 
taxpayers. Not all tax expenditures that affect individuals are 
shown in this table because of the difficulty in making 
reliable estimates of the income distribution of items that do 
not appear on tax returns under present law.
