* Less than 0.05
** Insufficient data
(1) Calendar year. Baseline is current law. Proposal would reduce statutory individual income tax rates to 8, 12, 20, 23, 27, and 28 percent. For a description of TPC's current law and current policy baselines, see http://www.taxpolicycenter.org/T11-0270
(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 2011 dollars): 20% $19,342; 40% $39,862; 60% $69,074; 80% $119,546; 90% $169,987; 95% $242,597; 99% $629,809; 99.9% $2,868,534.
(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 2011 dollars): 20% $13,687; 40% $26,567; 60% $44,163; 80% $72,423; 90% $104,181; 95%

(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.

(1) Calendar year. Baseline is current law. Proposal would reduce statutory individual income tax rates to 8, 12, 20, 23, 27, and 28 percent. For a description of TPC's current law and current policy http://www.taxpolicycenter.org/T11-0270
(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 2011 dollars): 20% $13,687; 40% $26,567; 60% $44,163; 80% $72,423; 90% $104,181; 95%
$147,975; 99% $384,375; 99.9% $1,764,281.
(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.

Note: Elderly tax units are those with either head or spouse (if filing jointly) age 65 or older.
(1) Calendar year. Baseline is current law. Proposal would reduce statutory individual income tax rates to 8, 12, 20, 23, 27, and 28 percent. For a description of TPC's current law and current policy http://www.taxpolicycenter.org/T11-0270
(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 2011 dollars): 20% $13,687; 40% $26,567; 60% $44,163; 80% $72,423; 90% $104,181; 95%
$147,975; 99% $384,375; 99.9% $1,764,281.
(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.
