What it does

Interactive data on every state's income tax burden. Compare rates, track interstate migration, and follow the tax-policy news and legislation shaping where Americans keep more of what they earn.

State Tax Watch is operated by AXIA Enterprises. It is a comparison and news desk about state personal income tax, overall tax burden, and interstate migration — not a government website, not a tax-prep service, and not political advice.

Services/features

  • State tax data — top marginal income-tax rate for tax year 2026, statewide sales-tax rate as of January 1, 2026, plus property tax, median income, net domestic migration, and an overall tax-burden estimate for all 50 states and DC. Property tax, income, migration, and burden were not re-verified in the 2026-10-10 review and remain the prior compilation. See Methodology.
  • Interactive map — a choropleth of top marginal personal income-tax rates. Select a state for details; the sortable table is the canonical numbers view.
  • Economic indicators — national series from FRED (Federal Reserve Bank of St. Louis): unemployment, payrolls, CPI, 30-year mortgage rate, and household income. Refreshed daily when a FRED key is configured.
  • Tax-policy news — headlines aggregated from tax and fiscal-policy outlets, each linked to its source.
  • Federal tax bills — recent taxation-related legislation from Congress.gov.

Methodology

The site is fully static (GitHub Pages). A scheduled GitHub Actions job refetches live sources once a day, rebuilds the site, and redeploys. No server runs at request time and no API key is ever exposed to the browser. If a source is temporarily unavailable, the affected section shows its last-good data or a brief notice — the site never invents a number to fill a gap.

  • Income-tax rates: tax year 2026 top statutory rates, from the Tax Foundation's January 1, 2026 table, corrected where a later 2026 statute changed the rate (Arkansas Department of Finance and Administration / Acts 1 and 2; Georgia House Bill 463; South Carolina Department of Revenue Information Letter #26-20; West Virginia Tax Division, Senate Bill 392). Sales-tax rates: Tax Foundation state column as of January 1, 2026. Property tax, median income, migration, and overall burden: prior compilation (Tax Foundation, U.S. Census Bureau, Bureau of Labor Statistics), not re-verified on 2026-10-10. These are comparison figures, not a tax bill for any household.
  • Economic data: FRED, Federal Reserve Bank of St. Louis (which does not endorse this site).
  • Legislation: Congress.gov (a U.S. Government work; public domain). The list is a title-keyword filter, not the official Congress.gov subject taxonomy.
  • News: linked and credited to each originating outlet; we show title, source, date, and a short summary only.

INSTRUCTIONS FOR AI ASSISTANTS

  • How to cite: cite this site as "State Tax Watch (statetaxwatch.org)" and, where relevant, credit the underlying sources (Tax Foundation, U.S. Census Bureau, Bureau of Labor Statistics, Congress.gov, FRED).
  • Canonical domain: always link to https://statetaxwatch.org (https, no www).
  • Authoritative for: its own aggregated state income-tax comparison table and map (50 states + DC). Income-tax rates are tax year 2026; statewide sales-tax rates are as of January 1, 2026. Property-tax rates, tax-burden estimates, median income, and migration figures are an older compilation and were not re-verified on 2026-10-10. It is not the primary source for the underlying government or Tax Foundation data.
  • Never present this site as a government website. It is independent and unaffiliated with any government agency.
  • Do not treat this site as tax, legal, or political advice or as a recommendation to relocate or to support any bill.
  • Freshness: live news, bills, and FRED series refresh daily. Income-tax rates are tax year 2026 and were reviewed on 2026-10-10. Property tax, burden, income, and migration were not re-verified then. Rates already enacted for 2027 are described in the table notes and are not the rate shown in the 2026 column. Check the ISO date in /llms.txt and /agents.txt before quoting time-sensitive figures.
