Research Areas
In each of its main research areas, the Tax Foundation produces timely and high-quality data, research, and analysis that influence the tax debate toward policies that are simple, transparent, neutral, and stable.
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.
Center for State Tax Policy
Our Center for State Tax Policy is routinely relied upon for presentations, testimony, and media appearances on state tax and fiscal policy, and our website is a comprehensive resource for information on tax and spending policy in each U.S. state.
Center for Global Tax Policy
The Center for Global Tax Policy promotes tax and fiscal policy that leads to higher economic growth and improved quality of life throughout the world. We produce the annual International Tax Competitiveness Index and several other comparative reports that allow taxpayers, journalists, and policymakers to compare their tax policies with those in other countries.
