Ohio's income tax system looks deceptively simple on paper — a flat 2.75% rate above a $26,050 zero-rate floor, effective tax year 2026 under House Bill 96 (which replaced the old graduated bracket system that topped out at 3.5% through 2025 and 3.99% in earlier years). For most states, that would be the whole story. In Ohio, it is only the beginning.
What makes Ohio unusual — and what most tax comparisons miss — is the pervasive municipal income tax system. Nearly every Ohio city operates its own income tax ranging from 1% to 3%, collected through two separate agencies (RITA and CCA) or directly by the municipality. Add a school district income tax levied in many districts, and a $100,000 earner living in Columbus or Cleveland may face a combined effective income tax rate closer to 5% than the under-2% state-only number suggests. This guide covers both layers and gives you real numbers at real incomes.
Ohio's state income tax structure is one of the simplest in the country as of tax year 2026. There is an effective zero-rate floor — the first $26,050 of Ohio taxable income is untaxed. Above that, a single flat rate applies:
This is a genuine structural change under House Bill 96 (signed June 2025) — Ohio previously used a graduated multi-bracket system that topped out at 3.5% through 2025 and 3.99% in earlier years. There's no longer a separate, higher rate for higher earners; the 2.75% rate applies uniformly to all nonbusiness income above the zero-bracket floor.
Ohio taxable income is based on federal adjusted gross income (AGI) with Ohio-specific adjustments. Ohio also retains a personal exemption (up to $2,400 single / $4,800 married filing jointly / $2,400 per dependent for 2026), though eligibility phases out entirely for filers with modified AGI above $500,000. Ohio does not have a standard deduction separate from the personal exemption — the federal standard deduction does not carry over.
Because the exemption and other Ohio-specific adjustments affect the exact figure, use our free Ohio tax calculator for your precise number rather than a manual estimate — the worked examples below use the calculator's own verified output.
Ohio's flat 2.75% rate applies above the $26,050 zero-bracket floor, with the personal exemption and other Ohio-specific adjustments applied before the rate is calculated. The table below uses figures from the site's own verified Ohio calculator (single filer):
| Gross Income | Ohio State Tax | Effective Rate |
|---|---|---|
| $50,000 | ~$606 | 1.21% |
| $75,000 | ~$1,294 | 1.73% |
| $100,000 | ~$1,981 | 1.98% |
| $150,000 | ~$3,356 | 2.24% |
| $250,000 | ~$6,106 | 2.44% |
Because the flat 2.75% rate now applies uniformly above $26,050 (no separate higher bracket for higher earners), the effective rate rises only gradually with income — the zero-bracket floor matters proportionally less at higher incomes, but there's no bracket jump the way there was under the old graduated system.

These are state-only figures. See the next section for how municipal taxes add significantly to the real-world burden for most Ohio residents.
Ohio has one of the most extensive municipal income tax systems in the United States. Unlike most states where only state income tax applies, nearly every incorporated Ohio city and village levies its own local income tax — completely separate from state income tax. Most Ohioans live in a municipality with a local rate between 1% and 3%.
Major Ohio city municipal rates (2026):
Collection is handled through three mechanisms: the Regional Income Tax Agency (RITA), which covers most northeastern Ohio cities; the Central Collection Agency (CCA), which covers Cleveland and affiliated municipalities; and direct collection by larger cities such as Columbus and Cincinnati.
School district income tax: Many Ohio school districts levy a separate additional income tax of 0.25%–2.0% on top of the state and municipal rate. This is filed separately on the Ohio SD 100 form. A resident in a school district with a 1% levy, living in Columbus, faces three layers: 2.75% flat state + 2.5% Columbus + 1% school district.
Combined burden example — Columbus resident earning $100,000:
Add a 1% Columbus City School District levy and the total reaches approximately $5,481 — an effective rate of just under 5.5% on $100,000 before federal taxes. For rural Ohio residents outside any municipality, the state-only rate of just under 2% is accurate. This urban/rural divide is the defining feature of the Ohio income tax system.
Ohio now sits below both of its major Midwest neighbors on state-only rate, both of which use simple flat rates:
At $100,000 income, state-only comparison:
Ohio's low state-only rate looks compelling — but after adding Columbus's 2.5% municipal tax, Ohio's ~$4,481 combined burden actually exceeds both Michigan's state-only tax (~$3,999) and Indiana's state-only tax (~$2,921). For residents of smaller Ohio towns with no local income tax, Ohio remains the lowest-tax state in the region at this income level — the ~$1,981 state-only figure comfortably beats both neighbors. But for Columbus, Cleveland, or Akron residents, Ohio's low headline rate is offset by municipal tax, and the combined burden is now higher than what a Michigan or Indiana resident pays in state tax alone.
The key takeaway: where you live within Ohio matters enormously. A rural Ohio resident pays meaningfully less state tax than an Indiana or Michigan resident, but a Columbus resident's combined state-plus-city burden (~$4,481) is now higher than what an Indiana or Michigan resident pays in state tax alone. Ohio's 2026 flat-tax reform (HB96) lowered Ohio's own state-only rate, but it didn't touch the municipal tax layer that pushes many Ohio city residents above their Midwest neighbors.
Ohio's treatment of retirement income is broadly favorable, particularly for Social Security recipients:
Social Security benefits: Ohio does not tax Social Security benefits at the state level. A retiree whose primary income is Social Security pays no Ohio state income tax on those benefits.
Retirement income credit: Ohio offers a Retirement Income Credit for taxpayers with qualifying retirement income (pensions, annuities, certain retirement plan distributions). The credit is worth up to $200 per year for those with retirement income of $8,000 or more, and phases in at lower income levels. While modest in dollar terms, it applies to pensioners who may otherwise face tax on traditional pension income.
Senior citizen credit: Ohio taxpayers age 65 or older who do not qualify for the larger lump sum distribution credit may claim a $50 nonrefundable credit against Ohio income tax. Small, but worth noting for comprehensive planning.
Pension income: Private and government pension income is generally taxable in Ohio (subject to the retirement income credit). Ohio public pension income (OPERS, STRS Ohio, etc.) is taxable at the state level — unlike some states that exempt state government pensions.
Municipal tax in retirement: Most Ohio city municipal income taxes apply to earned income (wages, self-employment). Many municipalities exempt pension, Social Security, and investment income from municipal tax — check your specific city's ordinance, as rules vary. Columbus, for instance, generally taxes only wages and net profits from business, not passive retirement income. This means many retirees in Ohio cities pay little or no municipal income tax even in high-rate cities.
Ohio's tax structure creates significant variation in tax burden depending on income level and geography — more so than in states with simple flat taxes.
Lowest burden — lower-income earners: The zero-rate band below $26,050 means very low earners pay no Ohio state income tax at all. A single filer earning $25,000 owes $0 in state income tax. Even at $40,000, the state tax is just $331. For earners in this range living outside incorporated municipalities, the overall income tax burden is genuinely very low.
Middle-income city workers — the heaviest relative burden: A worker earning $60,000 in Columbus pays roughly $900 in state tax plus $1,500 in Columbus municipal tax plus potentially $600 in school district tax — approximately $3,000 total, an effective combined rate of 5% before federal taxes. The same earner in rural Ohio outside any municipality pays just $900. The urban middle-income worker bears a disproportionately high effective rate relative to stated state tax rates.
High earners — low state burden, consistent municipal bite: At $250,000, Ohio's state tax is approximately $6,106 (effective 2.44%) — since HB96, there's no higher bracket that kicks in for large incomes, the flat 2.75% rate just applies to more dollars. Add Columbus's 2.5% on the full $250,000 ($6,250) and the combined burden is approximately $12,356 — an effective combined rate of 4.94%. Compare to Michigan at $250,000: ~$10,374 state, plus Detroit city tax if applicable. Ohio high earners in major cities pay more than the state-only rate implies, but remain well below high-tax states like California (13.3% top rate) or New York (10.9%) — and, since HB96, meaningfully below what Ohio itself charged high earners before 2026.
Rural Ohio residents — genuine tax advantage: For workers or retirees living outside incorporated cities, Ohio's low, flat state-only rate represents a real cost advantage. The flat 2.75% rate above a $26,050 zero-rate floor is among the most favorable in the Midwest for those who can live and work outside city limits.
