Historical Effective Federal Tax Rates: 1979 to 2002

March 1, 2005

The following tables update the series of historical effective tax rates estimated by the Congressional Budget Office (CBO) by providing values for an additional year—2002. The tables show effective tax rates for the four largest sources of federal revenue—individual income taxes, corporate income taxes, payroll taxes, and excise taxes—as well as the total effective rate for the four taxes combined. The tables also present average pretax and after-tax household income; counts of households; and shares of taxes, income, and households for each fifth (quintile) of the income distribution and for the top percentiles of households.
