Help us achieve a world where the tax code doesn't stand in the way of success.
The Tax Foundation is the nation’s leading independent tax policy nonprofit. Since 1937, our principled research, insightful analysis, and engaged experts have informed smarter tax policy at the federal, state, and global levels. For over 80 years, our goal has remained the same: to improve lives through tax policies that lead to greater economic growth and opportunity.
Following the passage of the Tax Cuts and Jobs Act, the debate on tax reform has shifted from Washington, D.C., to all fifty states. States incorporate provisions of the federal tax codes into their own codes in varying degrees, meaning that federal tax reform has implications for state revenue.
Because the base-broadening provisions of the new federal tax law often flow through to states, while the corresponding rate reductions do not, most states will experience a revenue increase from federal tax reform – although several states could see decreases, largely due to the new federal pass-through provisions.
States are busy working to quantify the impact to their state budgets from the federal tax changes to ensure they have all the necessary information about their policy choices.
Below we have catalogued each state’s projected revenue impact of federal tax reform. We will update this page as new estimates are released.
