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 General Equilibrium Model, known as our Taxes and Growth (TAG) 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.
The Tax Foundation uses and maintains a General Equilibrium Model, known as our Taxes and Growth (TAG) Model to simulate the effects of government tax and spending policies on the economy and on government revenues and budgets.

The One Big Beautiful Bill Act makes many of the individual tax cuts and reforms of the TCJA permanent. It improves upon the TCJA by making expensing for R&D and equipment permanent. However, for the most part, it does not include further structural reforms, and instead introduces many new, narrow tax breaks to the code, adding complexity and raising revenue costs.
