Fifty states, over 7,300 state legislators, and over 100,000 bills: legislative sessions are a whirlwind. But the Tax Foundation and its state experts are here to help make sense of the key tax policy issues in state capitols.
This page is intended as a resource for policymakers and others focused on state-level tax policy, providing one-click access to key resources and highlighting papers on some of the biggest issues of 2026. It is also an open invitation to connect directly with our experts with questions or requests for legislative testimony. Contact information for the Tax Foundation expert assigned to each state can be found below.
The past five years have seen the majority of states adopt rate cuts, particularly to individual income taxes. Some states have gone even further by easing compliance costs for hybrid and remote workers, offering permanent full expensing of capital investments, and adopting other reforms to promote mobility and modernization in an increasingly competitive state tax landscape.
In addition to papers on major issues in contemporary tax policy, we also have resources like our six-part “boot camp” series for state lawmakers and others interested in state tax policy, along with publications like our State Tax Competitiveness Index (a comparison of the competitiveness of states’ tax structures) and Facts & Figures (a handy guide to state tax rates, collections, and burdens data). We invite you to treat this page as a launching point as you think about state tax policy issues throughout 2026.

For Congress, work on the One Big Beautiful Bill Act is done. But in state capitols, the work has not yet begun. Many of the tax changes in the federal reconciliation act flow through to state tax codes—automatically in some states, and subject to an update in states’ Internal Revenue Code conformity date in others.
