Some Members of Congress have expressed interest in the feasibility of using a value-added tax (VAT) to either replace all or part of the income tax or finance health care reform. A VAT is imposed at all levels of production on the differences between firms' sales and their purchases from all other firms. Policymakers may be interested in the following aspects of a VAT: revenue yield, international comparison of composition of taxes, vertical equity, neutrality, inflation, balance-of-trade, national saving, administrative cost, intergovernmental relations, size of government, and public opinion.
