Compare state income tax across all 50 states + DC — see whether your state has no tax, a flat rate, or graduated brackets.
States fall into three types: no income tax (9 states), a flat rate applied to all income, or graduated brackets where the rate rises with income. This tool shows which type your state uses and an estimate based on that. For graduated states, the figure shown is an upper-bound using the top marginal rate — your real effective rate will be lower.
Illustrative estimate only, using simplified/rounded 2026 state-level figures — not tax advice. Rates change, and many states add local/county taxes on top. Always confirm with your state's tax authority.
