** Insufficient data
(1) Calendar year. Baseline is current law. Proposal would a) increase the AMT exemption amounts to $79,850 for married couples filing a joint return, $51,150 for others
($39,925 for married individuals filing a separate return) and allow non-refundable credits against tentative AMT; b) extend the 2001 and 2003 tax cuts, including statutory marginal tax rates on ordinary income; repeal of limitation on itemized deductions (Pease) and the phase-out of personal exemptions (PEP); marriage penalty relief for the standard deduction, earned income tax credit, and 15 percent bracket; $1,000 per child amount for the child tax credit and partial refundability based on earnings in excess of
$10,000, indexed for inflation; expansion of child and dependent care tax credit; and the 0%/15% rate structure on capital gains and qualified dividends. Proposal would extend the top estate tax rate of 35 percent and an effective exemption of $5 million, indexed for inflation. For a description of TPC's current law and current policy baselines, see http://www.taxpolicycenter.org/T11-0270
(2) Tax units with negative income are excluded from the lowest income class but are included in the totals. For a description of income, see http://www.taxpolicycenter.org/TaxModel/income.cfm
(3) The 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 2012 dollars): 20% $24,125; 40% $48,424; 60% $80,181; 80% $133,185; 90% $180,192; 95% $252,055; 99% $596,998; 99.9% $2,858,701.
(4) Includes both filing and non-filing units but excludes those that are dependents of other tax units.
(5) After-tax income is 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 income.

(1) Calendar year. Baseline is current law. Proposal would a) increase the AMT exemption amounts to $79,850 for married couples filing a joint return, $51,150 for others ($39,925 for married individuals filing a separate return) and allow non-refundable credits against tentative AMT; b) extend the 2001 and 2003 tax cuts, including statutory marginal tax rates on ordinary income; repeal of limitation on itemized deductions (Pease) and the phase-out of personal exemptions (PEP); marriage penalty relief for the standard deduction, earned income tax credit, and 15 percent bracket; $1,000 per child amount for the child tax credit and partial refundability based on earnings in excess of $10,000, indexed for inflation; expansion of child and dependent care tax credit; and the 0%/15% rate structure on capital gains and qualified dividends. Proposal would extend the top estate tax rate of 35 percent and an effective exemption of $5 million, indexed for inflation. For a description of TPC's current law and current policy baselines, see http://www.taxpolicycenter.org/T11-0270
(2) Tax units with negative income are excluded from the lowest income class but are included in the totals. For a description of income, see http://www.taxpolicycenter.org/TaxModel/income.cfm
(3) The 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 2012 dollars): 20% $16,596; 40% $31,921; 60% $50,160; 80% $78,784; 90%
$109,140; 95% $150,645; 99% $349,271; 99.9% $1,697,732.
(4) Includes both filing and non-filing units but excludes those that are dependents of other tax units.
(5) After-tax income is 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 income.

(1) Calendar year. Baseline is current law. Proposal would a) increase the AMT exemption amounts to $79,850 for married couples filing a joint return, $51,150 for others ($39,925 for married individuals filing a separate return) and allow non-refundable credits against tentative AMT; b) extend the 2001 and 2003 tax cuts, including statutory marginal tax rates on ordinary income; repeal of limitation on itemized deductions (Pease) and the phase-out of personal exemptions (PEP); marriage penalty relief for the standard deduction, earned income tax credit, and 15 percent bracket; $1,000 per child amount for the child tax credit and partial refundability based on earnings in excess of $10,000, indexed for inflation; expansion of child and dependent care tax credit; and the 0%/15% rate structure on capital gains and qualified dividends. Proposal would extend the top estate tax rate of 35 percent and an effective exemption of $5 million, indexed for inflation. For a description of TPC's current law and current policy baselines, see http://www.taxpolicycenter.org/T11-0270
(2) Tax units with negative income are excluded from the lowest income class but are included in the totals. For a description of income, see http://www.taxpolicycenter.org/TaxModel/income.cfm
(3) The 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 2012 dollars): 20% $16,596; 40% $31,921; 60% $50,160; 80% $78,784; 90%
$109,140; 95% $150,645; 99% $349,271; 99.9% $1,697,732.
(4) Includes both filing and non-filing units but excludes those that are dependents of other tax units.
(5) After-tax income is 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 income.
