Number of AMT Taxpayers (millions). Baseline: 21.0
Proposal: 21.0
(1) Calendar year. Baseline is current law. Proposal would impose an additional 0.9% tax on earnings for single filers in excess of $200,000 ($250,000 for married
couples filing a joint return) as defined for purposes of the Hospital Insurance Tax. An additional tax of 2.9% would be imposed on investment income. Investment
income would include taxable interest, dividends, net positive capital gains, net positive income from rents, net positive income from royalties, and net positive passive
income from partnerships and S corporations. The unearned income surtax would not exceed 2.9% of a single filer's adjusted gross income in excess of $200,000
($250,000 for married couples filing a joint return). The thresholds would be indexed for inflation.
(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% $19,599, 40% $37,843, 60% $66,647, 80% $113,886, 90% $164,974, 95% $231,179, 99% $624,396, 99.9% $2,875,812.
(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.

(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% $13,465, 40% $25,159, 60% $42,626, 80% $69,583, 90% $100,255, 95% $141,875, 99% $375,887, 99.9%
$1,773,679.
(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. Proposal would impose an additional 0.9% tax on earnings for single filers in excess of $200,000 ($250,000 for married couples filing a joint return) as defined for
purposes of the Hospital Insurance Tax. An additional tax of 2.9% would be imposed on investment income. Investment income would include taxable interest, dividends, net positive capital gains, net positive
income from rents, net positive income from royalties, and net positive passive income from partnerships and S corporations. The unearned income surtax would not exceed 2.9% of a single filer's adjusted
gross income in excess of $200,000 ($250,000 for married couples filing a joint return). The thresholds would be indexed for inflation.
(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% $13,465, 40% $25,159, 60% $42,626, 80% $69,583, 90% $100,255, 95% $141,875, 99% $375,887, 99.9%
$1,773,679.
(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 impose an additional 0.9% tax on earnings for single filers in excess of $200,000 ($250,000 for married couples filing a joint return) as defined for
purposes of the Hospital Insurance Tax. An additional tax of 2.9% would be imposed on investment income. Investment income would include taxable interest, dividends, net positive capital gains, net positive
income from rents, net positive income from royalties, and net positive passive income from partnerships and S corporations. The unearned income surtax would not exceed 2.9% of a single filer's adjusted gross
income in excess of $200,000 ($250,000 for married couples filing a joint return). The thresholds would be indexed for inflation.
(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% $13,465, 40% $25,159, 60% $42,626, 80% $69,583, 90% $100,255, 95% $141,875, 99% $375,887, 99.9%
$1,773,679.
(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.
