                              INTRODUCTION

    Tax expenditure analysis can help both policymakers and the 
public to understand the actual size of government, the uses to 
which government resources are put, and the tax and economic 
policy consequences that follow from the implicit or explicit 
choices made in fashioning legislation. This report \1\ on tax 
expenditures for fiscal years 2011-2015 is prepared by the 
staff of the Joint Committee on Taxation (``Joint Committee 
staff'') for the House Committee on Ways and Means and the 
Senate Committee on Finance. The report also is submitted to 
the House and Senate Committees on the Budget.

    The Joint Committee staff has made its estimates (as shown 
in Table 1) based on the provisions in Federal tax law as 
enacted through January 10, 2011. Expired or repealed 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. The tax 
expenditure calculations in this report are based on the 
January 2011 Congressional Budget Office (``CBO'') revenue 
baseline and Joint Committee staff projections of the gross 
income, deductions, and expenditures of individuals and 
corporations for calendar years 2010-2015.
    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 2011-2015 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 (Pub. 
L. No. 93-344), sec. 3(3). The Budget Act requires CBO and the Treasury 
to publish annually detailed lists of tax expenditures. The Joint 
Committee staff issued reports prior to the statutory obligation placed 
on the CBO and continued to do so thereafter. In light of this 
precedent and a subsequent statutory requirement that the CBO rely 
exclusively on Joint Committee staff estimates when considering the 
revenue effects of proposed legislation, the CBO has always relied on 
the Joint Committee staff for the production of its annual tax 
expenditure publication. See Pub. L. No. 99-177, sec. 273, codified at 
2 U.S.C. 601(f).
---------------------------------------------------------------------------
    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 similar to those direct 
spending programs that are available as entitlements to those 
who meet the statutory criteria established for the programs.
    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. 
It is appropriate to evaluate tax expenditures with respect to 
cost, distributional consequences, alternative means of 
provision, and economic effects and to allow policymakers to 
evaluate the tradeoffs among these and other potentially 
competing policy goals.
    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. 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 less than 
$50 million over the five fiscal years 2011-2015. 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.
    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.\5\ 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.\6\ 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 in this report.
---------------------------------------------------------------------------
    \5\ The Federal income tax on individuals also applies to estates 
and trusts, which are subject to a separate income tax rate schedule 
(sec. 1(e) of the Code). 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.
    \6\ Other analysts have explored applying the concept of tax 
expenditures to 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, Bruce F. 
Davie, ``Tax Expenditures in the Federal Excise Tax System,'' National 
Tax Journal, 47, March 1994, pp. 39-62, and Lindsay Oldenski, 
``Searching for Structure in the Federal Excise Tax System: An Excise 
Tax Expenditure Budget,'' National Tax Journal, 57, September 2004, pp. 
613-637. Prior to 2003, the President's budget contained a section that 
reviewed and tabulated estate and gift tax provisions that the Treasury 
considered tax expenditures.
---------------------------------------------------------------------------
    Some provisions in the Internal Revenue Code (``the 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 two-percent floor on itemized deductions for 
unreimbursed employee expenses. Tax provisions that provide 
treatment less favorable than normal income tax law and are not 
related directly to progressivity are called negative tax 
expenditures.\7\ Special provisions of the law the principal 
purpose for which is to enforce general tax rules, or to 
prevent the violation of other laws, are not treated as 
negative tax expenditures even though they may increase the tax 
burden for certain taxpayers. Examples of these compliance and 
enforcement provisions include (1) the section 382 limitation 
on net operating loss carryforwards and certain built-in losses 
following ownership changes, (2) the section 1091 wash sale 
rules, (3) the section 1287 denial of capital gain treatment 
for gains on certain obligations not in registered form, and 
(4) the section 162(f) disallowance of a deduction for fines 
and penalties.
---------------------------------------------------------------------------
    \7\ Although the Budget Act does not require the identification of 
negative tax expenditures, the Joint Committee staff has presented a 
number of negative tax expenditures for completeness.
---------------------------------------------------------------------------
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 are classified as exceptions to normal income tax 
law.
    The Joint Committee staff views the personal exemptions and 
the standard deduction as defining the zero-rate bracket that 
is a part of normal tax law. An itemized deduction that is not 
necessary for the generation of income is classified as a tax 
expenditure, but only to the extent that it, when added to a 
taxpayer's other itemized deductions, exceeds the standard 
deduction.
    All employee compensation is subject to tax unless the Code 
contains a specific exclusion for the income. Specific 
exclusions for employer-provided benefits include: coverage 
under accident and health plans,\8\ accident and disability 
insurance, group term life insurance, educational assistance, 
tuition reduction benefits, transportation benefits (parking, 
van pools, and transit passes), dependent care assistance, 
adoption assistance, 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, and de minimis fringe benefits). Each of these 
exclusions is classified as a tax expenditure in this report.
---------------------------------------------------------------------------
    \8\ Present law contains an exclusion for employer-provided 
coverage under accident and health plans (sec. 106) and an exclusion 
for benefits received by employees under employer-provided accident and 
health plans (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 generally 
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 partially excluded or fully excluded 
from gross income.\9\ Under normal income tax law, retirees 
would be entitled to exclude 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 railroad retirement benefits in excess of 
payroll tax payments is classified as a tax expenditure.
---------------------------------------------------------------------------
    \9\ For taxpayers with modified adjusted gross incomes above 
certain levels, up to 85 percent of social security and tier 1 railroad 
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, the value of Medicare Part B 
insurance generally is greater than the Part B premium that 
enrollees must pay, and the value of Medicare Part D 
(prescription drug) insurance generally is greater than the 
Part D 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, as are the 
exclusion of the value of Medicare Part B insurance in excess 
of Part B premiums and the exclusion of the value of Part D 
insurance in excess of Part D premiums.
    Public assistance benefits are excluded from gross income 
by statute or by Treasury regulations. Table 1 contains tax 
expenditure calculations 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.\10\ 
However, the Joint Committee staff does not classify this 
exclusion as a tax expenditure.\11\ 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\ 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.
---------------------------------------------------------------------------
    \10\ The National Income and Product Accounts include estimates of 
this imputed income. The accounts appear in Survey of Current Business, 
published monthly by the U.S. Department of Commerce, Bureau of 
Economic Analysis. However, a taxpayer-by-taxpayer accounting of 
imputed income would be necessary for a tax expenditure estimate.
    \11\ The Treasury Department provides a tax expenditure calculation 
for the exclusion of net rental income of homeowners that combines the 
positive tax expenditure for the failure to impute rental income with 
the negative tax expenditure for the failure to allow a deduction for 
depreciation and other costs.
    \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.
---------------------------------------------------------------------------
    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, exchange, 
gift, or transfer at death. Thus, the deferral of tax until 
realization is not classified as a tax expenditure. However, 
reduced rates of tax, further deferrals of tax (beyond the year 
of sale, exchange, gift, or transfer at death), and exclusions 
of certain capital gains are classified as tax expenditures. 
Because of the same concern for administrative feasibility, 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.
    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, 
then: (1) the income that is received at the time the option is 
exercised is excluded for purposes of the regular income tax 
but, in the case of an incentive stock option, included for 
purposes of the alternative minimum tax (``AMT''); (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. The negative tax 
expenditure created by the denial of the deduction for 
employers is incorporated in the calculation of the tax 
expenditure.
---------------------------------------------------------------------------
    \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 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. In two cases the 
restrictive effects of the AMT are presented separately because 
there are no underlying positive tax expenditures reflecting 
these effects: the negative tax expenditures for the AMT's 
disallowance of personal exemptions and the standard deduction; 
and the net AMT attributable to the net operating loss 
limitation.

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.
    Some economists assert that this may not represent the 
difference between tax depreciation and economic depreciation. 
In particular, some economists have found that economic 
depreciation follows a geometric pattern, as opposed to a 
straight-line pattern, because data suggest that a geometric 
pattern more closely matches the actual pattern of price 
declines for most asset types. The Bureau of Economic Analysis 
(``BEA'') of the Department of Commerce introduced a new 
methodology for calculating economic depreciation for purposes 
of the National Income and Product Accounts (``NIPA'') in 1997 
that relies on constant (geometric) rates of depreciation 
rather than the straight-line method used previously and 
embodied in the alternative depreciation system. This analysis 
is based on separate lives and depreciation rates for each of 
dozens of types of assets, unlike the tax depreciation 
rules.\14\ A somewhat similar result could be reproduced 
mathematically using the straight-line method and adjusting the 
recovery period. The straight-line method could be used over a 
shorter or longer recovery period to provide for a present 
value of tax depreciation greater than, equal to, or less than 
the present value of economic depreciation.\15\
---------------------------------------------------------------------------
    \14\ For a detailed discussion of the BEA methodology, see Barbara 
M. Fraumeni, ``The Measurement of Depreciation in the U.S. National 
Income and Product Accounts,'' Survey of Current Business, 77, July 
1997, pp. 7-23.
    \15\  Tax expenditures are calculated on a cash flow basis such 
that two methods of depreciation with equivalent present value may 
produce both positive and negative tax expenditure estimates on a year 
by year basis relative to economic depreciation.
---------------------------------------------------------------------------
    In addition, a tax expenditure has been measured for 
depreciation in those specific cases where the tax treatment of 
a certain type of asset deviates from the overall treatment of 
other similar types of assets. For example, the tax treatment 
of leasehold improvements of commercial buildings is 
depreciated using a recovery period of 15 years, while the 
general treatment of improvements to commercial buildings 
(e.g., owned commercial buildings) is a 39 year recovery 
period. In this case, the difference between depreciation (in 
this case straight line) using 15 years and 39 years for the 
recovery period represents a tax expenditure. In Table 1, these 
items are reflected in the various tax expenditure estimates 
for depreciation. 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 (nor, for that matter, 
any indexing with respect to expenses associated with these 
assets). Thus, normal income tax law would not take into 
account the effects of inflation on tax depreciation.
    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 (except where its 
application is deemed infeasible), 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.) As 
another example, the deductions for contributions to nuclear 
decommissioning trust accounts and certain environmental 
settlement trust accounts are not viewed as tax expenditures 
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 incomes of these two 
types of trust accounts, and these tax rate reductions are 
viewed as tax expenditures.
    The Joint Committee staff assumes that normal income tax 
law would provide for the carryback and carryforward of net 
operating losses. The staff also assumes that the general 
limits on the number of years that such losses may be carried 
back or forward were chosen for reasons of administrative 
convenience and compliance concerns and may be assumed to 
represent normal income tax law. Exceptions to the general 
limits on carrybacks and carryforwards are viewed as tax 
expenditures.

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 directly 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.\16\
---------------------------------------------------------------------------
    \16\  See discussion of the individual AMT above.
---------------------------------------------------------------------------
    Certain income of pass-through entities is exempt from the 
corporate income tax. The income of sole proprietorships, S 
corporations, most partnerships, and other entities (such as 
regulated investment companies, real estate investment trusts, 
real estate mortgage investment conduits, and cooperatives) 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 
section 501 also generally are exempt from corporate income 
tax. The tax exemption for organizations that have a direct 
business analogue or compete with for-profit organizations 
organized for similar purposes is a tax expenditure.\17\ The 
tax exemption for certain nonprofit cooperative business 
organizations, such as trade associations, is not treated as a 
tax expenditure just as the entity-level exemption given to 
for-profit pass-through business entities is not treated as a 
tax expenditure. 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. However, there are 
numerous exceptions that allow for otherwise unrelated business 
income to escape taxation,\18\ and these exceptions are treated 
as tax expenditures. 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, as is the exclusion of income 
granted to holders of tax-exempt financing issued by charities.
---------------------------------------------------------------------------
    \17\ These organizations include small insurance companies, mutual 
or cooperative electric companies, State credit unions, and Federal 
credit unions.
    \18\ These exceptions include certain passive income that arguably 
may relate to business activities, such as royalties or rents received 
from licensing trade names or other assets typically used in a trade or 
business, as well as other passive income such as certain dividends and 
interest. Other exceptions include income derived from certain research 
activities and income from certain trade show and fair activities.

Comparisons with Treasury 

    The Joint Committee staff and Treasury lists of tax 
expenditures differ in at least six respects. First, the Joint 
Committee staff and the Treasury use differing methodologies 
for the estimation of tax expenditures. Thus, the estimates in 
Table 1 are not necessarily comparable with the estimates 
prepared by the Treasury. Under the Joint Committee staff 
methodology, each tax expenditure is measured by the difference 
between tax liability under present law and the tax liability 
that would result if the tax expenditure provision were 
repealed and taxpayers were allowed to take advantage of any of 
the remaining tax expenditure provisions that apply to the 
income or the expenses associated with the repealed tax 
expenditure.
    For example, the tax expenditure provision for the 
exclusion of employer-paid health insurance is measured by the 
difference between tax liability under present law and the tax 
liability that would result if the exclusion were repealed and 
taxpayers were allowed to claim the next best tax treatment for 
the previously excluded employer-paid health insurance. This 
next best tax treatment could be the inclusion of the employer-
paid health insurance as an itemized medical deduction on 
Schedule A.\24\
---------------------------------------------------------------------------
    \24\ If the exclusion were repealed, the value of the employer-paid 
health insurance would be included in income and taxpayers would be 
treated as having purchased the insurance themselves. Thus, the 
insurance expense would be deductible as an itemized medical expense on 
Schedule A, subject to the itemized medical deduction floor (7.5 
percent (10 percent for taxable years beginning after December 31, 
2012) of the taxpayer's adjusted gross income).
---------------------------------------------------------------------------
    Under the Treasury methodology, each tax expenditure is 
measured by the difference between tax liability under present 
law and the tax liability that would result if the tax 
expenditure provision were repealed and taxpayers were 
prohibited from taking advantage of any of the remaining tax 
expenditure provisions that apply to the income or the expenses 
associated with the repealed tax expenditure. For example, the 
tax expenditure provision for the exclusion for employer-paid 
health insurance is measured by the difference between tax 
liability under present law and the tax liability that would 
result if the exclusion were repealed and taxpayers were 
required to include all of the employer-paid health insurance 
in income, with no offsetting deductions (i.e., no 
deductibility on Schedule A).
    Second, 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 
broader definition of the normal income tax base. Thus, the 
Joint Committee list of tax expenditures includes some 
provisions that are not contained in the Treasury list. The 
cash method of accounting by certain businesses 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.
    Third, the Joint Committee staff and the Treasury estimates 
of tax expenditures may also differ as a result of differing 
data sources and differences in baseline projections of incomes 
and expenses. The Treasury's tax expenditure calculations are 
based on the Administration's economic forecast. The Joint 
Committee staff calculations are based on the economic forecast 
prepared by the CBO.
    Fourth, the Joint Committee staff and the 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 2010-2016. The Joint Committee staff estimates 
cover a recent fiscal year and the succeeding four fiscal 
years, i.e., fiscal years 2011-2015.
    Fifth, 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 2011 through 2015. 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 2010 through 2016.
    Finally, the Joint Committee staff list formally integrates 
negative tax expenditures into its standard presentation.
    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.
    There are some tax expenditure provisions that are 
contained in the Treasury list but are not contained in the 
Joint Committee staff list. Two of these 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.\25\ The capital gains treatment 
of royalties on coal is included with the estimate of gain or 
loss in the case of timber, coal, and iron ore.
---------------------------------------------------------------------------
    \25\ See discussion of the passive loss rules above.
                  II. MEASUREMENT OF TAX EXPENDITURES

Tax Expenditure Calculations 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.\26\ Taxpayer behavior is assumed to 
remain unchanged for tax expenditure estimate purposes.\27\ 
This assumption is made to simplify the calculation and conform 
to the presentation of government outlays. This approach to tax 
expenditure measurement is in contrast to the approach taken in 
revenue estimating; all Joint Committee staff revenue estimates 
reflect anticipated taxpayer behavior.
---------------------------------------------------------------------------
    \26\ 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. For positive tax expenditures, the major difference 
between outlay equivalents and the tax expenditure calculations 
presented here is accounting for whether a tax expenditure converted 
into an outlay payment would itself be taxable, so that a gross-up 
might be needed to deliver the equivalent after-tax benefits.
    \27\ An exception to this absence of behavior in tax expenditure 
calculations is that a taxpayer is assumed to make simple additions or 
deletions in filing tax forms, what the Joint Committee staff refers to 
as ``tax form behavior.'' For example, as noted above, if the exclusion 
for employer-paid health insurance were repealed, taxpayers would be 
allowed to claim the next best tax treatment for the previously 
excluded insurance. This next best tax treatment could be the inclusion 
of the employer-paid health insurance as an itemized medical deduction 
on Schedule A. Similarly, a taxpayer that is eligible for one of two 
alternative credits is assumed to file for the second credit if the 
first credit is eliminated.
---------------------------------------------------------------------------
    The tax expenditure calculations in this report are based 
on the January 2011 CBO revenue baseline and Joint Committee 
staff projections of the gross income, deductions, and 
expenditures of individuals and corporations for calendar years 
2010-2015. 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 (or that will 
be denied in the case of negative tax expenditures) 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 
calculations in this report are based on projections of actual 
claims under the various tax provisions, not the potential tax 
benefits to which taxpayers are entitled.
    Some tax expenditure calculations 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 calculated separately, under the 
assumption that all other tax expenditures remain in the 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.\28\
---------------------------------------------------------------------------
    \28\ See Leonard E. Burman, Christopher Geissler, and Eric J. 
Toder, ``How Big Are Total Individual Income Tax Expenditures, and Who 
Benefits from Them?'' American Economic Review, 98, May 2008, pp. 79-
83.
---------------------------------------------------------------------------
    Year-to-year differences in the calculations 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. For example, the dollar level of tax expenditures 
tends to increase and decrease as tax rates increase and 
decrease, respectively, without any other changes in law. Some 
of the calculations 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 measurement techniques.
    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 mandate, 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.
Tax Expenditures versus Revenue Estimates 
    A tax expenditure calculation is not the same as a revenue 
estimate for the repeal of the tax expenditure provision for 
three reasons. First, unlike revenue estimates, tax expenditure 
calculations do not incorporate the effects of the behavioral 
changes that are anticipated to occur in response to the repeal 
of a tax expenditure provision. Second, tax expenditure 
calculations are concerned with changes in the reported tax 
liabilities of taxpayers.\29\ Because tax expenditure analysis 
focuses on tax liabilities as opposed to Federal government tax 
receipts, there is no concern for the short-term timing of tax 
payments. Revenue estimates are concerned with changes in 
Federal tax receipts that are affected by the timing of all 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. This FICA 
effect would be reflected in revenue estimates, but is not 
considered in tax expenditure calculations. There may also be 
interactions between income tax provisions and other Federal 
taxes such as excise taxes and the estate and gift tax.
---------------------------------------------------------------------------
    \29\ Reported tax liabilities may reflect compliance issues, and 
thus calculations of tax expenditures reflect existing compliance 
issues.
---------------------------------------------------------------------------
    If a tax expenditure provision were repealed, it is likely 
that the repeal would be made effective for taxable years 
beginning after a certain date. Because most individual 
taxpayers have taxable years that coincide with the calendar 
year, the repeal of a provision affecting the individual income 
tax most likely would be effective for taxable years beginning 
after December 31 of a certain year. However, the Federal 
government's fiscal year begins October 1. Thus, the revenue 
estimate for repeal of a provision would show a smaller revenue 
gain in the first fiscal year than in subsequent fiscal years. 
This is due to the fact that the repeal would be effective 
after the start of the Federal 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, and very often repeal or modification of a tax 
provision includes transition relief that would not be captured 
in a tax expenditure calculation.

                     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 
footnotes 5 and 9. For each of these items, the footnote means 
that the tax expenditure is less than $50 million in the fiscal 
year.
    Table 2 presents projections of 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.
