State-by-State Tax Guides
Every state and DC has its own guide: how its income tax works, who runs it, whether free state filing exists, and where to find the official forms. Pick your state below or scan the quick-reference table. Rates and rules change, so each guide links to the state’s own agency for current-year figures.

Quick reference: income tax type and filing agency
This table is a general classification as we understand it at the time of writing. States change rates and structures often (many have cut rates or moved toward flat taxes in recent years), so confirm with the state agency — or find yours in the Federation of Tax Administrators directory or USA.gov’s state taxes page. “No broad wage income tax” means no tax on ordinary wages; some of these states tax other things (for example, Washington taxes certain high capital gains, and New Hampshire repealed its interest and dividends tax after 2024). Massachusetts is listed as flat because most income is taxed at a single 5% rate, with a surtax on very high income.
