Tax Foundation

The Tax Foundation is an international research think tank based in Washington, D.C. that collects data and publishes research studies on U.S. tax policies at both the federal and state levels. Its stated mission is to "improve lives through tax policy research and education that leads to greater economic growth and opportunity". The Tax Foundation is organized as a 501(c)(3) tax-exempt non-profit educational and research organization, with three primary areas of research: the Center for Federal Tax Policy, the Center for State Tax Policy, and the Center for Global Tax Policy. The group is known for its annual reports such as the State Business Tax Climate Index, International Tax Competitiveness Index, and Facts & Figures: How Does Your State Compare, which was first produced in 1941.
