** This table is part of a series of tables showing the distributional effects of moving incrementally from current law to current policy. For definitions and further information, see “Related Tables: Moving Incrementally from Current Law to Current Policy” at http://taxpolicycenter.org/numbers/displayatab.cfm?template=simulation&SimID=366
(1) Calendar year. Baseline is current law plus a permanent AMT patch at 2009 levels, indexed for inflation; extension of low- and middle-income tax cuts (extend the 10, 25, and 28 percent rates; set the standard deduction and 10 and 15 percent tax brackets for couples filing jointly to double those for singles; raise the EITC phaseout threshold for couples filing jointly; and extend expansions of the student loan interest deduction, the Earned Income Tax Credit (EITC), the Child and
Dependent Care Tax Credit (CDCTC), and the Child Tax Credit (CTC); taxation of qualified dividends the same as long-term capital gains; reduced tax rates on longterm capital gains (0 percent for tax units in 15 percent bracket or lower, 15 percent for tax units in tax brackets above 15 percent). Policy is repeal of the personal exemption phaseout (PEP) and limitation on itemized deductions (Pease).
(2) Tax units with negative cash income are excluded from the lowest income class but are included in the totals. For a description of cash income, see http://www.taxpolicycenter.org/TaxModel/income.cfm
(3) The cash income percentile classes used in this table are based on the income distribution for the entire population and contain an equal number of people, not tax units. The breaks are (in 2009 dollars): 20% $19,356, 40% $37,493, 60% $65,656, 80% $111,659, 90% $161,739, 95% $226,402, 99% $599,181, 99.9% $2,727,123.
(4) Includes both filing and non-filing units but excludes those that are dependents of other tax units.
(5) After-tax income is cash income less: individual income tax net of refundable credits; corporate income tax; payroll taxes (Social Security and Medicare); and estate tax.
(6) Average federal tax (includes individual and corporate income tax, payroll taxes for Social Security and Medicare, and the estate tax) as a percentage of average cash income.

(3) The cash income percentile classes used in this table are based on the income distribution for the entire population and contain an equal number of people, not tax units. The incomes used are adjusted for family size by dividing by the square root of the number of people in the tax unit. The resulting percentile breaks are (in 2009 dollars): 20% $13,219, 40% $24,782, 60% $41,864, 80% $68,188, 90% $97,830, 95% $138,709, 99% $361,983, 99.9%

(4) Includes both filing and non-filing units but excludes those that are dependents of other tax units.
(5) After-tax income is cash income less: individual income tax net of refundable credits; corporate income tax; payroll taxes (Social Security and Medicare); and estate tax.
(6) Average federal tax (includes individual and corporate income tax, payroll taxes for Social Security and Medicare, and the estate tax) as a percentage of average cash income.

(1) Calendar year. Baseline is current law plus a permanent AMT patch at 2009 levels, indexed for inflation; extension of low- and middle-income tax cuts (extend the 10, 25, and 28 percent rates; set the standard deduction and 10 and 15 percent tax brackets for couples filing jointly to double those for singles; raise the EITC phaseout threshold for couples filing jointly; and extend expansions of the student loan interest deduction, the Earned Income Tax
Credit (EITC), the Child and Dependent Care Tax Credit (CDCTC), and the Child Tax Credit (CTC); taxation of qualified dividends the same as long-term capital gains; reduced tax rates on long-term capital gains (0 percent for tax units in 15 percent bracket or lower, 15 percent for tax units in tax brackets above 15 percent). Policy is repeal of the personal exemption phaseout (PEP) and limitation on itemized deductions (Pease).
(2) Tax units with negative cash income are excluded from the lowest income class but are included in the totals. For a description of cash income, see http://www.taxpolicycenter.org/TaxModel/income.cfm
(3) The cash income percentile classes used in this table are based on the income distribution for the entire population and contain an equal number of people, not tax units. The incomes used are adjusted for family size by dividing by the square root of the number of people in the tax unit. The resulting percentile breaks are (in 2009 dollars): 20% $13,219, 40% $24,782, 60% $41,864, 80% $68,188, 90% $97,830, 95% $138,709, 99% $361,983, 99.9%
$1,670,467.
(4) Includes both filing and non-filing units but excludes those that are dependents of other tax units.
(5) After-tax income is cash income less: individual income tax net of refundable credits; corporate income tax; payroll taxes (Social Security and Medicare); and estate tax.
(6) Average federal tax (includes individual and corporate income tax, payroll taxes for Social Security and Medicare, and the estate tax) as a percentage of average cash income.

15 percent bracket or lower, 15 percent for tax units in tax brackets above 15 percent). Policy is repeal of the personal exemption phaseout (PEP) and limitation on itemized deductions (Pease).
(2) Tax units with negative cash income are excluded from the lowest income class but are included in the totals. For a description of cash income, see http://www.taxpolicycenter.org/TaxModel/income.cfm
(3) The cash income percentile classes used in this table are based on the income distribution for the entire population and contain an equal number of people, not tax units. The incomes used are adjusted for family size by dividing by the square root of the number of people in the tax unit. The resulting percentile breaks are (in 2009 dollars): 20% $13,219, 40% $24,782, 60% $41,864, 80% $68,188, 90% $97,830, 95% $138,709, 99% $361,983, 99.9%
$1,670,467.
(4) Includes both filing and non-filing units but excludes those that are dependents of other tax units.
(5) After-tax income is cash income less: individual income tax net of refundable credits; corporate income tax; payroll taxes (Social Security and Medicare); and estate tax.
(6) Average federal tax (includes individual and corporate income tax, payroll taxes for Social Security and Medicare, and the estate tax) as a percentage of average cash income.
