Ohio uses graduated (progressive) state income tax brackets in 2026, so the rate rises with income much like the federal system. This calculator applies an estimated effective rate of about 2.8% for a middle income — on a $75,000 salary a single filer pays roughly $2,063 in state tax and nets about $59,530 a year (79.4% of gross). Your exact rate depends on where your income lands across the brackets.

Because Ohio is a graduated-rate state, your top marginal rate is higher than your effective rate — you only pay the top rate on income above each threshold, not on your whole salary. Use the interactive calculator below and adjust the state-rate field to match your income for a precise figure. The 2.8% estimate here is below the 4.8% average across taxing states.

Remember that FICA is separate from income tax and is not affected by your state. Every worker pays 6.2% for Social Security on the first $184,500 of wages (the 2026 wage base) plus 1.45% for Medicare on all wages. Pre-tax 401(k) and HSA contributions lower your federal and state income tax but do not reduce FICA — a detail that trips up a lot of first-time budgeters.

Ohio has compressed what was once a nine-bracket system down to just two rates, with the first several tens of thousands of dollars untaxed at the state level. But Ohio is also one of the heaviest users of municipal income taxes in America: hundreds of cities and villages levy their own wage taxes, commonly 1–2.5% (Columbus, Cleveland, and Cincinnati all charge them), generally based on where you work, with partial credits from your home city. Your municipality matters as much as the state rate.
