Calculate state income tax for any US state. Covers no-tax states, flat-rate states, and progressive-rate states.
Nine states have no income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire and Tennessee only tax investment income.
Flat tax states charge the same rate regardless of income (e.g., Illinois at 4.95%). Progressive states have multiple brackets where higher income is taxed at higher rates.
This uses simplified rates for illustration. Actual state tax calculations vary with deductions, credits, and specific bracket structures. Consult your state's tax authority for exact rates.
