Tax Proposal Calculator

The Urban-Brookings Tax Policy Center (TPC) has created a calculator to help show how the Tax Cuts and Jobs Act (TCJA) would affect sample taxpayers. You can use the default options we created for people in various income groups, or you can create your own taxpayer profile.

If you want to see how we created the defaults scenarios, click here. For a detailed description of the methodology behind this calculator, see our methodology page.

TPC's Tax Calculator estimates how the TCJA affects typical taxpayers. To make it easy to use, we left out many items which would be included on an actual tax return. Thus, the TPC calculator is not a tax preparation tool and the results it produces cannot be applied to specific tax situations.

TPC welcomes any feedback on the calculator, either on design or on how we modeled the provisions of the bill, as we are constantly working to improve our products. You can email info@taxpolicycenter.org with comments.

The Tax Policy Center (TPC) is a joint venture of the Urban Institute and Brookings Institution. The Center is made up of nationally recognized experts in tax, budget, and social policy who have served at the highest levels of government. It aims to provide independent analyses of current and longer-term tax issues and to communicate its analyses to the public and to policymakers in a timely and accessible manner. The Center combines top national experts in tax, expenditure, budget policy, and microsimulation modeling to concentrate on four overarching areas of tax policy that are critical to future debate.
