Ohio income tax goes up to 2.75% at the top bracket. Calculate your combined federal + state effective tax rate for 2026. Formula shown, sources cited — no account required.
Ohio's income tax system uses a graduated structure with a top marginal rate of 2.75%, low by any national comparison. Recent reforms simplified the brackets and pushed more low-income earners completely off the state tax rolls. The median earner at $72,212 likely pays a combined effective state rate of around 2%, leaving the federal burden as the primary driver of total tax liability. At the federal level, a median Ohio household typically falls into the 22% marginal bracket, putting combined effective rates in the 18–22% range depending on deductions. One important nuance: Ohio municipalities can and do levy local income taxes independently of the state. Living in Columbus, Cleveland, or Cincinnati typically adds 2.0–2.5% to your effective rate. The state exempts Social Security benefits from income tax, which matters for retirees. The tax bracket calculator helps you see how Ohio's state rate, your federal bracket, and any applicable local tax combine into your actual effective rate.
Ohio Tax Brackets Explained: Low State Rate Keeps Bills Down (2026)
Ohio has a state income tax with a top marginal rate of 2.75%. On top of federal rates (10%–37%), residents can face a combined marginal rate exceeding 35% at higher income levels. However, your effective rate is always lower than the marginal rate because only income above each threshold is taxed at that bracket's rate.
The median household in Ohio earns $72,212/year. At that income (single filer), the federal effective rate is approximately 12–14%, bringing total income tax (federal + state) to roughly 14–16%.
How Marginal vs. Effective Rate Works
The marginal rate is the rate on your last dollar of income — it does not apply to all income. The effective rate is your total tax divided by total income. For example, someone earning $100,000 in Ohio has a 22% federal marginal rate but an effective federal rate of roughly 15%, because the first $44,725 (2024) is taxed at 10% and 12%, not 22%.
