Center for Federal Tax Policy

Our Center for Federal Tax Policy educates taxpayers, journalists, and policymakers on tax policy at the federal level and how the U.S. tax system compares internationally. The Center’s Taxes and Growth (TAG) macroeconomic model has been used to analyze dozens of legislative and campaign tax proposals and their impact on taxpayers and the U.S. economy.
