You are exempt from Ohio income tax when your Ohio taxable income lands in the state’s 0% bracket, which for tax year 2025 covers everyone at or below $26,050.1Ohio Department of Taxation. Annual Tax Rates You can also reach zero at higher income levels because Ohio starts with your federal adjusted gross income and then subtracts things like Social Security, military pay, and certain retirement income before applying the brackets. School district income tax is a separate question with its own answer: if your district doesn’t levy the tax, or levies it on an earned income base that doesn’t touch your kind of income, you owe nothing there either. An Ohio income tax exemption, in practice, is usually a combination of the 0% bracket, the Schedule of Adjustments deductions, and the nonrefundable credits.
The 0% Bracket
Ohio’s rate schedule begins at zero. For tax year 2025:
- $0 to $26,050: 0%
- $26,050 to $100,000: $342 plus 2.75% of the amount over $26,050
- Over $100,000: $2,394.32 plus 3.125% of the amount over $100,000
These rates apply to Ohio taxable nonbusiness income.1Ohio Department of Taxation. Annual Tax Rates Ohio taxable income is not the same as federal AGI. Ohio starts with federal AGI and then runs it through the Ohio Schedule of Adjustments, which can pull the number well below $26,050 even when the federal figure is higher.
Income Ohio Doesn’t Tax
The Schedule of Adjustments is where most people who look “too high” for the 0% bracket actually get there. Several categories come out before the tax is calculated.
Social Security. Ohio does not tax Social Security. Whatever portion is taxable on your federal return (line 6b) gets subtracted on the Schedule of Adjustments, so it never enters your Ohio taxable income.2Ohio Department of Taxation. Senior Citizens and Ohio Income Tax
Military pay and benefits. Military retirement pay, military injury relief fund grants, veteran disability severance payments, and certain Ohio National Guard benefits are all deductible. Combat zone pay excluded federally stays excluded in Ohio automatically.3Ohio Department of Taxation. Military Servicemembers and Ohio Income Taxes
Other deductions. Certain railroad retirement benefits are fully deductible. Disability benefits, interest from Ohio public obligations, and unreimbursed medical expenses beyond what the federal return allows can also come off. Contributions to Ohio’s 529 college savings plan are deductible up to $4,000 per beneficiary per year, with unlimited carryforward for anything above that.2Ohio Department of Taxation. Senior Citizens and Ohio Income Tax
Credits That Zero Out What’s Left
If the Schedule of Adjustments doesn’t finish the job, Ohio’s nonrefundable credits can. These reduce your tax to zero but won’t generate a refund on their own.
- Retirement income credit: up to $200, if your modified AGI minus exemptions is under $100,000.4Ohio Department of Taxation. Ohio Tax Credits and Their Required Documentation
- Senior citizen credit: $50 for taxpayers 65 and older.2Ohio Department of Taxation. Senior Citizens and Ohio Income Tax
- Lump sum distribution credit: for certain one-time retirement payouts, calculated separately on the return.
Between the Social Security deduction, the retirement income credit, and the senior citizen credit, many Ohio retirees with modest pension and investment income owe nothing.
Exempt Because of Who You Are, Not What You Earn
Some people are effectively exempt from Ohio tax on income Ohio would otherwise reach, because of their residency status or federal law.
Nonresidents Without Ohio-Sourced Income
A full-year nonresident with no Ohio-sourced income has no Ohio tax liability and no filing obligation. Ohio-sourced income includes wages earned in the state, lottery and casino winnings, Ohio rental property income, and income from a business operating in Ohio.5Ohio Department of Taxation. Tax 101 A nonresident who does earn Ohio-sourced income pays only on that portion; the rest is removed through the nonresident credit.6Ohio Department of Taxation. Income – Ohio Residency and Residency Credits
Residency turns on domicile: your true, fixed, permanent home. Working out of state for a year doesn’t end an Ohio domicile. If your permanent home is in Ohio but you spent the year working elsewhere, Ohio still treats you as a resident and taxes your worldwide income.6Ohio Department of Taxation. Income – Ohio Residency and Residency Credits
Workers Covered by Reciprocity
Ohio has income tax reciprocity with all five bordering states: Indiana, Kentucky, Michigan, Pennsylvania, and West Virginia.7Ohio Department of Taxation. Employer Withholding – Reciprocity If you live in one of those states and work in Ohio, your wages should be withheld for your home state, not Ohio. To set that up, complete Section III of the Ohio IT 4 and give it to your employer.
If Ohio tax was withheld by mistake, you get it back by filing an Ohio IT 1040 and deducting the reciprocity wages on line 12 of Schedule A. Don’t use the IT AR refund form for this; the IT 1040 is the correct route.7Ohio Department of Taxation. Employer Withholding – Reciprocity
Military Servicemembers and Spouses
A servicemember whose legal residence is not Ohio is treated as a nonresident and can deduct military income on the Schedule of Adjustments even while stationed in Ohio. An Ohio-domiciled servicemember stationed elsewhere can deduct active duty pay and allowances, which typically wipes out their Ohio liability.3Ohio Department of Taxation. Military Servicemembers and Ohio Income Taxes
Under the Military Spouses Residency Relief Act, beginning with tax year 2023 married servicemembers and their spouses can choose the servicemember’s residence, the spouse’s residence, or the servicemember’s permanent duty station as their state of legal residence for income tax. A spouse keeping a non-Ohio legal residence while in Ohio on military orders can deduct their Ohio-earned income on the Schedule of Adjustments.3Ohio Department of Taxation. Military Servicemembers and Ohio Income Taxes
School District Income Tax Is a Separate Question
Being exempt from Ohio state tax doesn’t automatically exempt you from school district income tax, and vice versa. The school district tax is separate from state income tax, from any municipal income tax, and from property tax. You pay it based on where you live.8Ohio Department of Taxation. School District Income Tax
The first question is whether your district levies the tax at all. Most Ohio districts don’t. For tax year 2026, 214 districts impose an income tax.9Ohio Department of Taxation. School District Tax Year 2026 If yours isn’t on the list, there’s no school district liability. To check, use the Department of Taxation’s online lookup, “The Finder,” which returns your district number, rate, and tax base type from your street address.10Ohio Department of Taxation. The Finder – School District Income Tax
Traditional vs. Earned Income Base
Districts that do levy the tax use one of two bases, and the difference is significant for retirees and people living on investments.
A traditional base district taxes your modified adjusted gross income minus exemptions. That reaches pensions, investment returns, and retirement distributions. Most of the 214 taxing districts use this method for 2026.9Ohio Department of Taxation. School District Tax Year 2026
An earned income base district taxes only wages and net self-employment earnings. Sixty-eight districts use this method for 2026.9Ohio Department of Taxation. School District Tax Year 2026 If you live in one of these and your income comes from Social Security, pensions, or investments, your school district liability is zero. A retiree in a traditional district owes tax on pension income; the same retiree across the boundary in an earned income district owes nothing.
One thing that catches people: a credit for city income tax doesn’t reduce school district tax, and school district withholding doesn’t offset city tax. Those are independent layers, and you can owe both alongside state tax.8Ohio Department of Taxation. School District Income Tax
File the Return Even When You Owe Nothing
Ohio-required filing doesn’t disappear just because your tax works out to zero. You must file an Ohio IT 1040 if you are a resident, part-year resident, or nonresident with Ohio-sourced income.5Ohio Department of Taxation. Tax 101
If your liability is zero and you’re not owed a refund, Ohio offers a shorter form: the IT 10. It’s built for taxpayers in one of these situations: no tax liability on Ohio income, full-year nonresident with no Ohio-sourced income, nonresident military servicemember whose only Ohio income is military pay, or civilian spouse of a nonresident servicemember stationed in Ohio.11Ohio Department of Taxation. 2025 Ohio IT 10 Zero Liability No Refund Individual Income Tax Return Catch: if you owe any school district income tax, you can’t use the IT 10 and have to file the full IT 1040.
For school district tax, file the SD 100. Traditional base districts use Schedule A; earned income base districts use Schedule B. Filing a zero SD 100 is recommended even when you’re confident nothing is owed, because the Department of Taxation otherwise sends delinquency notices and estimates liability without your deductions or credits.
The state deadline is April 15. A federal extension automatically extends Ohio to October 15, but any estimated tax owed is still due April 15 to avoid interest.
Documents worth keeping with the return:
- W-2s, to verify withholding and which state received it if you work across state lines.
- 1099-Rs, showing sources of retirement distributions for the deductions and credits.
- Military orders, to establish non-Ohio domicile for servicemembers and spouses.
- A copy of the Ohio IT 4 you gave your employer, particularly for reciprocity claims.
Nonresident or military spouse claims are supported by a completed Form IT-NRS (Ohio Nonresident Statement) if the Department questions your status.
What Happens If You Claim an Exemption You Don’t Qualify For
Ohio charges interest on unpaid balances and can impose penalties for late filing and underpayment. At the federal level, filing a return whose information indicates the self-assessment is substantially incorrect can trigger a $5,000 civil penalty for frivolous tax submissions, and that penalty stacks on top of anything else owed.12Office of the Law Revision Counsel. 26 USC 6702 – Frivolous Tax Submissions
The more common problem is quieter. Skip a return Ohio thinks you owed, and the Department sends a delinquency notice with its own estimated liability, usually without any of the deductions or credits you would have claimed. Filing a zero-liability return upfront is always cheaper than arguing with an assessment later. When in doubt, file and claim the deductions that bring the balance to zero.
