Effective Federal Tax Rates: 1979 to 2001

April 1, 2004

Updating the series of historical effective tax rates estimated by the Congressional Budget Office (CBO) and presented in a recent paper, Effective Federal Tax Rates, 1997 to 2000, the following tables provide values for an additional year—2001.

The tables show effective tax rates for the four largest sources of federal revenues--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 the top percentiles of households.
