Yes, Ohio does have a state income tax. For 2026, Ohio charges a single flat rate of 2.75% on nonbusiness income above roughly $27,350, and 0% on income at or below that amount. Residents are taxed on all their income no matter where it was earned; nonresidents are taxed only on income from Ohio sources. And the state rate is only part of the picture, because most Ohioans also owe local income taxes to a municipality, a school district, or both.
The 2026 Rate and the 0% Bracket
Starting in 2026, Ohio consolidated its brackets into one flat rate. Taxable nonbusiness income of $27,350 or less is taxed at 0%. Every dollar above that is taxed at 2.75%.1Ohio.gov. Ohio H.B. 30 Bill Analysis, 136th General Assembly This is a simplification from prior years. In 2024, Ohio had two brackets at 2.75% and 3.5%, and in 2025 the top rate was 3.125%.2Ohio Department of Taxation. Annual Tax Rates
The 0% bracket acts as a built-in exemption. Someone with $27,350 or less in Ohio taxable income owes the state nothing. Someone earning $80,000 pays 2.75% only on the portion above $27,350, or about $1,448. Business income follows a separate set of rules, discussed further down.
Who Has to Pay
Your residency status determines what Ohio can tax. The state sorts filers into three groups: full-year resident, part-year resident, and nonresident.3Ohio Department of Taxation. What Does Ohio Residency Mean for Taxes
- If Ohio is your permanent home, you’re a full-year resident, and Ohio taxes all your income no matter where you earned it.4Ohio Department of Taxation. IT Archive – Personal Income Tax – Residency Guidelines
- If you moved into or out of Ohio during the year, you’re a part-year resident. You owe tax on everything earned while you lived in Ohio, plus any Ohio-sourced income from the period you lived elsewhere.
- If you never lived in Ohio but earned money there, you’re a nonresident and owe Ohio tax only on that Ohio-sourced income.4Ohio Department of Taxation. IT Archive – Personal Income Tax – Residency Guidelines
Military servicemembers are taxed by their state of legal residence, not the state where they’re stationed. Ohio residents on active duty outside the state can deduct their military pay. Civilian spouses of nonresident servicemembers stationed in Ohio generally don’t owe Ohio tax on their wages.
If You Live in a Neighboring State and Work in Ohio
Ohio has reciprocal agreements with Indiana, Kentucky, Michigan, Pennsylvania, and West Virginia. If you live in one of those states and work in Ohio, your Ohio employer generally won’t withhold Ohio tax from your paycheck, and you’ll file and pay only to your home state. The reverse is true for Ohio residents commuting into those five states.5Ohio Department of Taxation. Employer Withholding – Reciprocity
Reciprocity covers only wages and salaries. Rental income, business profits, and investment gains earned across state lines are not covered, so you may still owe Ohio tax on those. Ohio does offer a resident credit for taxes paid to another state on the same income, which prevents double taxation on non-wage income.3Ohio Department of Taxation.

How Ohio Figures Your Taxable Income
Ohio starts with your federal adjusted gross income, the number at the bottom of page one of your federal 1040. You then apply Ohio-specific additions and subtractions on the Schedule of Adjustments to get your Ohio adjusted gross income.6Ohio Department of Taxation. Income – General Information
The subtractions that matter most to typical filers:
- Ohio does not tax Social Security. Any taxable Social Security income in your federal AGI gets deducted in full on the Ohio Schedule of Adjustments.7Ohio Department of Taxation. Senior Citizens and Ohio Income Tax
- Active duty military pay is deductible for Ohio residents stationed outside the state.
- Contributions to Ohio’s 529 college savings plan are deductible up to $4,000 per beneficiary for single filers and $8,000 for joint filers. Beginning in 2026 those limits are indexed for inflation.8Ohio.gov. Ohio H.B. 48 Bill Analysis, 136th General Assembly
After subtractions, you apply personal exemptions. The amount depends on income: $2,400 per person if your AGI is $40,000 or less, $2,150 if your AGI is between $40,001 and $80,000, and $1,900 if your AGI is between $80,001 and $500,000. If your modified adjusted gross income exceeds $500,000, the personal exemption disappears entirely.
Business Income Is Taxed Differently
Ohio offers a large break for business owners. The first $250,000 of eligible business income ($125,000 if you file married filing separately) is fully deductible from Ohio taxable income. Anything above that deduction is taxed at a flat 3%, separate from the 2.75% rate that applies to nonbusiness income.9Ohio Department of Taxation. Business Income Deduction Information
The deduction covers income from sole proprietorships, partnerships, S corporations, and certain other pass-through entities. For many small business owners it effectively eliminates state tax on their business earnings. If you live in a school district that uses the traditional tax base (see below), however, the deduction gets added back when calculating school district tax.
Credits That Reduce What You Owe
Once your tax is calculated, credits cut the bill dollar-for-dollar.
- The retirement income credit is worth up to $200 based on the amount of retirement income (pensions, IRA distributions) included in your Ohio AGI.
- The senior citizen credit is a flat $50 per return for taxpayers age 65 or older with modified adjusted gross income below $100,000.10Ohio Department of Taxation. Retirement Income
- The joint filing credit is available to married couples filing jointly, and as of 2026 it phases out for taxpayers with modified adjusted gross income above $500,000.1Ohio.gov. Ohio H.B. 30 Bill Analysis, 136th General Assembly
- The resident credit lets Ohio residents offset taxes paid to another state on the same income. It doesn’t apply to wages from the five reciprocity states, since those wages should only be taxed by your home state to begin with.3Ohio Department of Taxation. What Does Ohio Residency Mean for Taxes
School District Income Tax
This is the tax that surprises many Ohio residents. As of January 2026, 210 school districts levy their own income tax on top of the state tax. Rates generally range from 0.5% to 2%, and you owe the tax if you lived in a taxing district at any point during the year and had income while you were a resident.11Ohio Department of Taxation. School District Income Tax
Districts use one of two methods to calculate what’s taxable:
- The traditional tax base uses your Ohio adjusted gross income minus exemptions, which pulls in wages, investment income, pensions, and capital gains.
- The earned income tax base taxes only wages, salaries, and net self-employment income. Retirement income, dividends, interest, and capital gains are excluded.
Which method your district uses was set by the ballot language when voters approved the tax. The difference matters most for retirees: on the earned income base, pension income is untouched; on the traditional base, pension income is taxable (Social Security remains excluded because it’s already deducted at the state level).12Ohio Department of Taxation. Guide to Ohio’s School District Income Tax
School district tax gets reported on a separate Form SD 100, filed alongside your state IT 1040. You can owe school district tax even when your state tax is zero, and in that case you still have to file both returns.11Ohio Department of Taxation. School District Income Tax
Municipal Income Taxes
Most Ohio cities and villages also impose their own income tax. Municipal rates are flat and typically range from 0.5% to 3%, applied to earned income like wages and business profits. If you live in one city and work in another, both can tax your earnings, though most cities offer a credit for taxes paid to your work city. Some cap that credit below their own rate, so the offset is not always complete.
Two regional agencies handle collection for hundreds of Ohio communities: the Central Collection Agency (CCA), based in Cleveland, and the Regional Income Tax Agency (RITA). If your municipality uses one of them, you’ll file your local return through the agency rather than directly with your city.13CCA – Division Of Taxation. Tax Rates
Deadlines and Late Penalties
Ohio individual income tax returns (Form IT 1040) are due April 15. If that date lands on a weekend or holiday, the deadline shifts to the next business day.14Ohio Department of Taxation. Due Dates You can file through Ohio’s OH|TAX eServices portal, through approved tax software, or on paper by mail.
Ohio automatically grants a six-month filing extension if you’ve filed a federal extension on IRS Form 4868. No separate Ohio form is required. But the extension only pushes the filing deadline; any tax you owe is still due April 15, and interest starts accruing on unpaid balances after that.15Ohio Department of Taxation. Ohio’s Individual and School District Income Tax Filing Extension
If you expect to owe more than $500 after subtracting withholding and credits, you should make quarterly estimated payments. For calendar-year filers these are due April 15, June 15, September 15, and January 15 of the following year.16Ohio.gov. 2026 Ohio Estimated Income Tax Instructions
Late-filing penalties can be steep. If you don’t file by the deadline (including extensions), the penalty is up to $50 per month or 5% of the unpaid tax per month, whichever is greater, capped at $500 or 50% of the tax owed. If you file on time but don’t pay, the penalty can reach twice the interest charged on the late payment. Fraudulent returns carry a penalty of the greater of $1,000 or 100% of the tax that should have been reported.17Ohio Legislative Service Commission. Ohio Revised Code 5747 – Section 5747.15 Interest runs on any unpaid balance from the original due date at the federal short-term rate plus five percentage points.
