Ohio has a tax reciprocity agreement with five neighboring states: Indiana, Kentucky, Michigan, Pennsylvania, and West Virginia. If you live in one of those states and earn wages in Ohio, only your home state taxes that paycheck. The protection runs both ways for Ohio residents who commute across the border. Reciprocity covers wages and salaries only, so business profits, rental income, and investment gains still follow normal multi-state rules.
Which States Have Reciprocity With Ohio
The five reciprocal states are the ones that share a border with Ohio. A resident of Indiana, Kentucky, Michigan, Pennsylvania, or West Virginia who works in Ohio owes state income tax only to the home state, and Ohio employers are not required to withhold Ohio income tax from those workers’ pay.1Ohio Department of Taxation. Employer Withholding An Ohio resident working in any of those five states gets the same deal in reverse.
Reciprocity is for compensation from personal services. Rent from property across the border, business income earned in the other state, and capital gains sourced there are not covered. For those, you file in both states and claim a credit for taxes paid to the other state so the same dollar isn’t taxed twice.
If You Live in a Reciprocal State and Work in Ohio
The Ohio withholding exemption is not automatic. File Ohio Form IT 4NR with your Ohio employer, which certifies that you live in a reciprocal state and tells payroll to skip Ohio state income tax withholding. Hand it to your employer’s payroll department before your first paycheck if you can.
Without the IT 4NR on file, your employer must withhold Ohio income tax as if you were a resident.1Ohio Department of Taxation. Employer Withholding Recovering that money means filing an Ohio Form IT 1040 to claim a refund. Treat the IT 4NR as day-one paperwork alongside your W-4.
If You Live in Ohio and Work Across the Border
Commuting out of Ohio works the same way, but each reciprocal state has its own form. Your out-of-state employer probably won’t offer it unprompted, so track it down and file it as early as possible. If you don’t, that state will withhold its income tax, Ohio will still expect what you owe at home, and you’ll be unwinding the double hit at tax time.

Ohio City Income Tax Still Applies
This is where reciprocity catches people off guard. The state-level agreement does not touch local income taxes, and Ohio has a lot of cities and villages that levy their own. Even with zero Ohio state tax owed, you can still owe municipal income tax to the Ohio city where you physically work.
Municipal rates generally run from 1.0% to 3.0% of earned income.4Regional Income Tax Agency. Tax Rates Table Your employer typically withholds the local tax for the city where your worksite sits, regardless of where you live, and nonresidents may need to file a local return with that city even when no Ohio state return is due.5CCA – Division of Taxation.

One exception helps occasional visitors. If you work in an Ohio city on twelve or fewer days in a calendar year, the city generally cannot tax your compensation for those days.6Ohio Legislative Service Commission. Ohio Revised Code 718.011 Track your days if you only occasionally travel to an Ohio worksite.
Ohio’s school district income tax is a separate levy, but nonresidents don’t owe it. It applies only to residents of the taxing district, so a commuter from a reciprocal state can ignore it.7Ohio Department of Taxation. Guide to Ohio’s School District Income Tax
Remote and Hybrid Work
Reciprocity turns on where you physically perform the work, not where your employer sits. Live in Michigan and drive to a Toledo office each day, and reciprocity clearly applies. Live in Michigan and work from home for an Ohio-based company, and the analysis shifts, because you’re performing services in Michigan. Ohio generally requires withholding from people earning compensation while “maintaining an office or transacting business within the state.”1Ohio Department of Taxation. Employer Withholding If you never set foot in Ohio, the case for Ohio withholding weakens considerably.
Hybrid schedules get messier. If you split time between a home office in a reciprocal state and an Ohio worksite, your employer may need to allocate your wages between the two. The Ohio portion is covered by reciprocity once you’ve filed the IT 4NR, but the municipal tax on days you actually worked at the Ohio location still applies. Keep a log of where you work each day if your schedule varies, because employers sometimes withhold conservatively and you may need to sort out the allocation when you file.
Military Spouses Stationed in Ohio
Federal law offers a separate protection worth knowing about. Under the Military Spouses Residency Relief Act, the spouse of a servicemember stationed in Ohio on military orders can keep the home state as their tax residence. Ohio-earned wages are taxed by the home state rather than Ohio, even if the home state isn’t one of the five reciprocal ones.
To qualify, you and your servicemember spouse must share the same state of legal residence, and you must be in Ohio solely because your spouse was ordered there. File Form IT MIL-SP (Exemption from Withholding – Military Spouse Employee) with your Ohio employer to stop Ohio withholding. This is a different form and a different legal basis than the IT 4NR, so file the correct one for your situation.
What If You Work in a State That Doesn’t Have Reciprocity
Reciprocity only covers the five bordering states. If you’re an Ohio resident working in New York, Illinois, or anywhere else, that state will withhold its income tax and no exemption is available. Ohio taxes its residents on all income regardless of where it was earned, which sets up the possibility of being taxed twice on the same wages.
Ohio handles that with a credit. You offset your Ohio tax liability by the income tax you paid to the non-reciprocal state, claimed on the Ohio Schedule of Credits with your Form IT 1040.8Ohio Department of Taxation. 2025 Ohio IT 1040 Individual Income Tax Return The credit is capped at the lesser of what you paid the other state or what Ohio would have charged on that income. You end up paying the higher of the two state rates, not both. Keep a copy of the other state’s return showing the tax you paid, because Ohio will want that documentation to support the credit.
