Yes, Ohio has a state income tax. For the 2026 tax year, Ohio charges a flat 2.75% rate on nonbusiness income above roughly $27,350, and 0% on income at or below that threshold.1Ohio.gov. Ohio H.B. 30 Bill Analysis, 136th General Assembly Residents pay Ohio tax on all income no matter where it was earned; nonresidents pay only on income from Ohio sources. On top of the state tax, most Ohioans also owe a municipal income tax to their city or village, and about 210 school districts levy their own income tax as well, so the state rate is only one piece of what you actually pay.
The 2026 Rate
Ohio consolidated its brackets into a single flat rate starting in 2026. If your taxable nonbusiness income is $27,350 or less, you owe nothing in state income tax. Every dollar above that threshold is taxed at 2.75%.1Ohio.gov. Ohio H.B. 30 Bill Analysis, 136th General Assembly
That is a step down from recent years. In 2024, Ohio ran a two-bracket system with a top rate of 3.5%. In 2025, the top rate was 3.125%. From 2026 forward it is a single 2.75%.2Ohio Department of Taxation. Annual Tax Rates
A simple example: someone with $80,000 in Ohio taxable income pays 2.75% only on the amount above $27,350, which works out to about $1,448 in state tax. Business income is taxed under separate rules covered further down.
Who Owes Ohio Income Tax
Ohio sorts filers into three residency categories, and your category decides what gets taxed.3Ohio Department of Taxation. What Does Ohio Residency Mean for Taxes
- Full-year residents owe Ohio tax on all of their income, whether earned in Ohio, in another state, or abroad.
- Part-year residents owe tax on everything earned while they lived in Ohio, plus any Ohio-sourced income from the part of the year they lived elsewhere.
- Nonresidents owe Ohio tax only on income from Ohio sources, such as wages from an Ohio employer or profits from an Ohio-based business.4Ohio Department of Taxation. IT Archive – Personal Income Tax – Residency Guidelines
Active-duty military members are taxed by their state of legal residence, not where they are stationed. Ohio residents on active duty outside Ohio can deduct their military pay from Ohio taxable income, and civilian spouses of nonresident servicemembers stationed in Ohio generally do not owe Ohio tax on their wages.
Reciprocity With Five Neighboring States
Ohio has reciprocal tax agreements with Indiana, Kentucky, Michigan, Pennsylvania, and West Virginia. If you live in one of those states and work in Ohio, your Ohio employer should not withhold Ohio income tax from your wages; you file and pay only in your home state. The same applies in reverse for Ohio residents commuting to a job in those five states.5Ohio Department of Taxation. Employer Withholding – Reciprocity
Reciprocity covers only employee wages. Rental income, business profits, and investment gains sourced across the state line are not covered, and both states may tax them. Ohio offers a resident credit for taxes paid to another state on the same income to prevent double taxation, but the credit does not apply to wages from the five reciprocity states, since those wages are not supposed to be taxed twice to begin with.3Ohio Department of Taxation.

How Ohio Taxable Income Is Calculated
Your Ohio return begins with your federal adjusted gross income, the figure from the bottom of page one of Form 1040. From there, you apply Ohio-specific additions and subtractions on the Schedule of Adjustments to reach your Ohio adjusted gross income.6Ohio Department of Taxation. Income – General Information
Common subtractions that reduce Ohio taxable income include:
- Social Security benefits. Ohio does not tax Social Security, so any amount that was taxable at the federal level gets deducted here.7Ohio Department of Taxation. Senior Citizens and Ohio Income Tax
- Military pay for Ohio residents stationed outside the state.
- Contributions to Ohio’s 529 college savings plan, up to $4,000 per beneficiary for single filers and $8,000 for joint filers. These limits are indexed for inflation beginning in 2026, so the actual deductible amount may run slightly higher.8Ohio.gov. Ohio H.B. 48 Bill Analysis, 136th General Assembly
After subtractions, personal exemptions reduce your income further. Ohio’s exemption is $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. Above $500,000, the exemption disappears.
Business Income Deduction
Business owners get a sizable break. The first $250,000 of eligible business income ($125,000 for married filing separately) is fully deductible from Ohio taxable income. Business income above that deduction is taxed at a flat 3%, separate from the 2.75% rate on 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, and it wipes out state income tax on business earnings for many small operators. If you live in a school district that uses the traditional tax base, you have to add this deduction back when calculating your school district tax.
Credits That Reduce Your Bill
Deductions reduce the income Ohio taxes. Credits reduce the tax itself, dollar for dollar. The most commonly used credits include:
- Retirement income credit of up to $200, based on the amount of pension or IRA distribution income in your Ohio AGI.
- Senior citizen credit of a flat $50 per return for taxpayers age 65 or older with modified AGI under $100,000.10Ohio Department of Taxation. Retirement Income
- Joint filing credit for married couples filing jointly, limited starting in 2026 to taxpayers with modified AGI of $500,000 or less.1Ohio.gov. Ohio H.B. 30 Bill Analysis, 136th General Assembly
- Resident credit for Ohio residents who pay income tax to another state on the same income (not available for wages from the five reciprocity states).3Ohio Department of Taxation. What Does Ohio Residency Mean for Taxes
School District Income Tax
This is the layer that surprises many Ohio residents. As of January 2026, 210 Ohio school districts levy an income tax on their residents, generally at rates between 0.5% and 2%. You owe the tax if you lived in a taxing district at any point in the year and had income while you lived there.11Ohio Department of Taxation. School District Income Tax
Districts use one of two methods, set when the tax was approved by voters:
- Traditional tax base. Taxes your Ohio adjusted gross income minus exemptions, which captures wages, investment income, pensions, and capital gains.
- Earned income tax base. Taxes only wages, salaries, and net self-employment income. Retirement income, dividends, interest, and capital gains are excluded.
The split matters most for retirees. In an earned-income district, pension income escapes school district tax. In a traditional district, pension income is taxable, though Social Security remains excluded because it was already removed at the state level.12Ohio Department of Taxation. Guide to Ohio’s School District Income Tax
School district tax is reported on Form SD 100, filed alongside your state return. You can owe school district tax even when your state tax is zero, and in that case both forms still have to be filed.11Ohio Department of Taxation. School District Income Tax
Municipal Income Tax
Most Ohio cities and villages also impose a local income tax, typically a flat 0.5% to 3% on earned income like wages and business profits. If you live in one municipality and work in another, both can tax your earnings; most cities give a credit for tax paid to the work city, though some cap that credit below their own rate, so you may still owe a small amount at home.
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 file your local return through the agency rather than directly with city hall. Your pay stub or employer can tell you which applies.13CCA – Division Of Taxation. Tax Rates
Filing Deadlines, Extensions, and Estimated Payments
Ohio individual income tax returns (Form IT 1040) are due April 15, moving to the next business day when April 15 falls on a weekend or holiday.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.
If you file a federal extension on IRS Form 4868, Ohio automatically grants you a matching six-month extension; no separate Ohio form is needed. The important catch: an extension gives you more time to file, not more time to pay. Any balance owed is still due April 15, and interest starts running on the unpaid amount after that date.15Ohio Department of Taxation. Ohio’s Individual and School District Income Tax Filing Extension
If you expect to owe more than $500 in Ohio income tax after withholding and credits, you should pay quarterly estimated tax.16Ohio.gov. 2026 Ohio Estimated Income Tax Instructions This typically hits self-employed workers, freelancers, and retirees with significant investment income. Calendar-year filers pay on April 15, June 15, September 15, and January 15 of the following year.14Ohio Department of Taxation. Due Dates Underpayment or missed installments can trigger interest when you file the annual return.
Penalties for Filing or Paying Late
Ohio penalizes late filing and late payment separately. The failure-to-file 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 due. If you file on time but pay late, the penalty can run up to twice the interest charged on the balance. Fraudulent returns carry a much steeper penalty: 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.
