Number: RL33665 Title: U.S. Federal Government Revenues: 1790 to the Present Authors: Thomas L. Hungerford, Government and Finance Division Abstract: The sources of federal government revenues have changed dramatically over the past 200 years. The nation has gone from almost exclusive reliance on customs duties to almost exclusive reliance on individual and corporate income taxes and payroll taxes as the means of funding the federal government. Along with the changing composition of federal revenues has come a significant increase in the share of national income devoted to funding the federal government. Pages: 15 Date: September 25, 2006
