Economic and Tax Modeling

The Tax Foundation’s Center for Federal Tax Policy takes a quantitative approach to analyzing the economic, budgetary, and distributional impact of important campaign, legislative, and other popular tax proposals using our dynamic Taxes and Growth (TAG) macroeconomic model.

The mission of our economic and tax modeling program is to educate lawmakers and the public about the key trade-offs in tax policy, the real-world impact of those trade-offs on taxpayers and our economy, and the best options for achieving principled and pro-growth tax reform.
