The Tax Foundation
The mission of the Tax Foundation is to educate taxpayers about sound tax policy and the size of the tax burden borne by Americans at all levels of government. From its founding in 1937, the Tax Foundation has been grounded in the belief that the dissemination of basic information about government finance is the foundation of sound policy in a free society.
