The Tax Foundation is a Washington, D.C.-based think tank founded in 1937 that collects data and publishes research studies on tax policies at the federal and state levels. The organization is broken into three primary areas of research which are the Center for Federal Fiscal Policy, The Center for State Fiscal Policy and the Center for Legal Reform. The group is known for its annual reports such as "Facts & Figures: How Does Your State Compare" which was first produced in 1941 and Tax Freedom Day for the United States, which it has produced since the early 1970s.
