N/A--Not applicable.

[1] Year-to-year comparability of the "all returns" total is
affected by changes in dollar income filing thresholds, while
year-to-year comparability of the number of returns by type of tax
form used is affected by changes in the specific filing
requirements, including adjustments for inflation, for each form.
In general, the filing of "short forms" (mostly Forms 1040A and
1040EZ) has been encouraged by IRS to simplify both taxpayer filing
requirements and IRS processing. Filing requirements for each of
the short forms have, therefore, been gradually liberalized to
facilitate their use. Increases in the number of short forms have
mostly been at the expense of "long form" 1040 usage (although
increases in the number of each of the short forms have often been
at the expense of one short form over another). While the number of
1040 (paper) returns has, therefore, increased over the time period
shown, the rate of increase has been reduced by the use of the
short forms, and, later, by electronic filing options (see below).
For additional information about the return filing requirements,
see the annual reports, Statistics of Income--Individual Income Tax
Returns. Forms 1040, 1040A, and 1040EZ include "standard"
electronically filed ("ELF" or "e-file") returns, and Form 1040EZ
returns filed electronically by telephone ("TeleFile"2000-2004
only). For 2006, the total number of Form 1040EZ returnes includes
742,859 Form 1040EZ-T returns.

[2] Taxpayers could elect to assign $3 of the income tax reported
on their returns ($6 on a joint return, if both spouses
contributed) to help pay for the cost of Presidential election
campaigns. To do so, a taxpayer had to check a box on the tax
return. The relationship between (a) the number of returns and
boxes checked and (b) the dollar amounts shown is only approximate
because the frequencies and the amounts were obtained from
different sources, the frequencies from Statistics of Income tax
return data and the dollar amounts from IRS monthly tax
collections, aggregated by calendar year. It should be noted that
the frequencies and amounts are related to the tax year for which
statistics are shown, even though the designation by the taxpayer
occurred in the following year, when the income tax return was
filed and processed.

[3] Less deficit.

[4] Taxable interest includes "dividends" on deposits and
withdrawable shares in mutual savings banks, savings and loan
associations, and credit unions, but excludes interest from
Regulated Investment Companies on money market mutual funds, which
is included in "dividends" in "adjusted gross income" (AGI).

[5] Not included in AGI. Represents interest on State and local
government obligations, including tax-exempt interest dividends
from Regulated Investment Companies.

[6] Dividends in AGI exclude capital gains and liquidating
dividends, reflected in the statistics for net capital gain or loss
in AGI, but include interest from Regulated Investment Companies on
money market mutual funds. Qualified dividends are the ordinary
dividends received after May 5, 2003, that met certain conditions.
These included: the dividend must have been paid by a U.S.
corporation or a "qualified" foreign corporation; the stock
ownership must have met certain holding period requirements; the
dividends were not from certain institutions, such as mutual
savings banks, cooperative banks, credit unions, tax-exempt
organizations, or farmer cooperatives; and the dividends were not
for any share of stock which was a part of an employee stock
ownership plan (ESOP).

[7] Rent net income (or loss) excludes sole proprietorship
(including farm) rental income or loss; these are included in
business or profession net income or loss. Rental losses are before
"passive loss" limitation and, therefore, exceed the amount
included in AGI.

[8] Losses are after "passive loss" limitation.

[9] Includes capital gains from the sale of assets held for
personal use or investment, and also net gains from the sale of
certain business property treated as net capital gains and from
"involuntary conversions" of property, such as by casualty or
theft. Also includes capital gains received from partnerships and S
corporations. See also footnote 15. Data represent total capital
gains. Total includes capital gain distributions from Regulated
Investment Companies. For other changes affecting capital gains,
see Statistics of Income--Individual Income Tax Returns , various
years. See also footnote 6.

[10] Includes capital losses (after limitation) from the sale of
assets held for personal use or investment, including losses in
excess of net gains from the sale of certain business property
treated as net capital losses and "involuntary conversions" of
property, such as by casualty or theft. Also includes capital
losses received from partnerships and S corporations. See also
footnotes 6, 15, and 16.

[11] Net gain or loss, not includable in capital gain or loss, from
the sale of business property (excluding inventories and certain
other assets) and "involuntary conversions" of property, such as by
casualty or theft. See also footnote 15.

[12] Excludes Individual Retirement Arrangement (IRA)
distributions.

[13] Represents total unemployment compensation.

[14] Up to 85 percent of Social Security benefits were taxable.

[15] Excludes certain royalties included in the computations of
capital gain or loss and of ordinary gain or loss in sales of
noncapital assets.

[16] Excludes capital gains and losses.

[17] Includes adjustments not shown separately in this table. Total
excludes certain business-related expenses, deduction for
two-earner married couples, and certain alimony payments, but
includes the self-employment health insurance deductions.

[18] Deductible Individual Retirement Arrangement (IRA)
contributions were limited, then liberalized somewhat.
Contributions to education and Roth IRAs were nondeductible and
are, therefore, not included in the statistics.

[19] Beginning in Tax Year 2004, a taxpayer could have taken a
deduction for contributions to a Health Savings Account. The
deduction was limited to the annual deductible on the qualifying
high deductible health plan and other criteria.

[20] Exemption amounts were indexed for inflation. Amounts were
also limited for taxpayers with high incomes. A check box on the
return was used for taxpayer's age 65 or over, in general, for use
in establishing claims for the additional standard deductions, but
many taxpayers not claiming the additional deductions also used the
check box. The amount shown for exemptions excludes amounts in
excess of AGI, which were reported but could not be used by the
taxpayer. The number of exemptions and amounts also excludes the
number and amounts reported on returns with no AGI, which did not
figure into the computation of tax as a result.

[21] In general, represents the sum of standard and itemized
deductions from AGI to compute "taxable income" (the tax base for
the regular income tax), but also includes deductions in excess of
AGI that could not be used in the computation. Deductions
erroneously reported on returns with no AGI were excluded from the
deduction statistics. Includes revised itemized deductions (see
also footnotes 23-24), "basic" standard deduction, and "additional"
standard deductions for age 65 or over or for blindness (for
changes in the standard deduction and its relation to the zero
bracket amount, see Statistics of Income--Individual Income Tax
Returns , for appropriate years). Total itemized deductions are
after statutory limitation (see footnote 25).

[22] Standard deductions were indexed for inflation. Statistics for
taxpayers with the additional standard deduction for age 65 or over
exclude those who checked the box on tax returns indicating age 65
or over, but then itemized their deductions instead of claiming
standard deductions (see footnote 20). For the percentages of AGI
used for the standard deduction and the limitation on the
deduction, see Statistics of Income--Individual Income Tax Returns.

[23] Includes itemized deductions not shown separately in this
table, including revised deductions, for "miscellaneous expenses"
after limitation and for employee moving expenses. In general,
total itemized deductions were limited for certain high-income
taxpayers. This limitation was indexed for inflation.

[24] Deductible medical and dental expenses were limited, based on
a revised percentage of AGI. The definition of expenses includes
payments for certain long-term care insurance premiums and for the
unreimbursed cost of certain long-term care of a chronically ill
individual.

[25] Starting with 2004, a taxpayer could have elected to deduct
State and local general sales taxes instead of State and local
income taxes as itemized deductions on Schedule A.

[26] Deductions for mortgage real estate loan interest were
limited. Personal interest was not deductible.

[27] Includes "alternative minimum tax" (AMT), starting with 2000.

[28] Different tax rate structures for the regular income tax
applied to Tax Years 2000-2002, 2003, 2004, 2005, and 2006.
Indexing of tax rate boundaries for inflation existed. The
preferential maximum tax rate on net long-term capital gains under
"alternative tax" was revised over the years. Alternative tax was
abolished, but a maximum capital gain tax rate less than the
maximum regular tax rate continued to apply under certain
conditions. For additional information on changes affecting tax
computations, see Table 23 of the appendix to the historical
section of this report and Statistics of Income--Individual Income
Tax Returns.

[29] Includes that portion of the "earned income credit" used to
offset income tax before credits. Earned income credit is shown
below in Table 1. See also footnote 33.

[30] Includes credits such as the low-income housing credit, child
adoption credit, and "empowerment zone employment" (EZE) credit not
shown separately.

[31] The statistics for all years shown are comparable. Starting
with Tax Year 2000, total income tax is, in general, the same as
income tax after credits, which was redefined to include AMT. (The
small difference between the two amounts for 2000 is due mainly to
the inclusion in the statistics for Tax Year 2000 of prior-year
returns filed in Calendar Year 2001 that were used as proxies for
Tax Year 2000 returns filed after 2001; the AMT on these returns
was included in total income tax, but not in income tax before or
after credits, consistent with the reporting sequence on the tax
return forms for these years. The same is true for Tax Year 2002
for prior returns filed in Calendar Year 2003 for Tax Year 2000 and
earlier. To a far lesser extent, the difference between total
income tax and income tax after credits represents the tax on
accumulation distributions of trusts, which was included in total
income tax only.) Total income tax reflects the amount reported on
the tax return and is, therefore, before any examination or
enforcement activities by the Internal Revenue Service. It
represents the income tax liability that was payable to the U. S.
Department of the Treasury.

[32] Under "alternative minimum tax" (AMT), generally high-income
taxpayers to whom the tax applied were required to pay the larger
of the regular income tax or the AMT. As of 2006, examples of
preferences or adjustments subject to recapture through the AMT
were accelerated depreciation, incentive stock options, certain
itemized deductions, personal exemptions, certain tax-exempt
interest, and income loss from tax-shelter farm or "passive"
investment activities. AMT is shown separately in the statistics
for all years. However, AMT is also included in "income tax before
credits," as well as in "income tax after credits" and "total
income tax."

[33] In Table 1, the amounts "used to offset income tax before
credits" and "used to offset other taxes" (that are income-related)
are reflected in the statistics for "total tax credits"; however,
"excess earned income credit (refundable)" is reflected in the
statistics for tax "overpayments." The refundable portion of the
credit is the amount (in excess of the taxes) that could not be
credited, including any "advance earned income credit payments" on
those returns that had such an excess. ("Advance earned income
credit payments" were made to employees electing to receive such
payments currently through their paychecks. Such "payments" are
included in the statistics only if the employees also met the tax
return filing requirements; advance payments received by those not
required to file are, therefore, excluded.)

[34] Represents payments reflecting the sum of "total income tax"
(see footnote 31), tax recapture of certain prior-year tax credits,
tax applicable to Individual Retirement Arrangements (IRAs), and
Social Security taxes on "self-employment income" and on certain
employee tip income, as well as on other income-related taxes
applicable to the years shown (see Statistics of Income--Individual
Income Tax Returns). The total also includes the following not
shown separately below in Table 1: "advance earned income credit
payments" and credits for (a) capital gain tax paid by a Regulated
Investment Company, but considered paid by shareholders, and (b)
part of the purchase price of a diesel-powered highway vehicle.

[35] Represents tax withheld on (a) salaries and wages; (b) certain
tip income; (c) pensions and annuities; (d) certain gambling
winnings; and (e) distributions from profit-sharing plans,
retirement plans, and Individual Retirement Arrangements (IRAs).
Also included are taxes withheld as a result of "backup
withholding" on certain interest, dividends, and royalty payments,
which otherwise were not subject to withholding.

[36] Represents the sum of (a) "estimated tax," generally paid
quarterly throughout the tax year by self-employed and certain
other taxpayers with insufficient or no tax withheld, and (b)
prior-year tax overpayments taxpayers elected to credit to their
current-year's "estimated tax" in lieu of requesting a refund.

[37] Represents the sum of payments made with a request for an
"automatic" 4-month extension of time in which to file an income
tax return, and payments with a request for an additional 2-month
extension. Notwithstanding the timing of these requests, full
payment of a tax estimate for the year had to be made with the
original application; if adjustments to the amount thus paid were
later necessitated, the difference was either refundable or payable
subject to an interest charge (which is not reflected in the tax
statistics).

[38] Includes refunds (shown separately), plus credits to the
following year's "estimated tax" and the refundable portion of the
"earned income credit" (see footnote 36). The taxes reflected in
tax overpayments are the same as those listed in footnote 35.

NOTES: Detail may not add to totals because of rounding. All
amounts are in current dollars. Most of the data are subject to
sampling error; tax law and tax form changes affect the
year-to-year comparability of the data.

SOURCE: Except for dollar amounts associated with the Presidential
election campaign checkoff, data are from Statistics of
Income--Individual Income Tax Returns , appropriate years.
Depending on the year, dollar amounts associated with the
Presidential election campaign checkoff were accumulated by
calendar year either from U.S. Treasury Department, Internal
Revenue Service, "Table S-1 Collections, Comparative Summary,
Document 7038," Report NO-Treas-103, monthly, or from unpublished
monthly data from Chief Financial Officer, Office of Finance,
Revenue Accounting Division, Office of Revenue Systems.
