Work in Ohio, Live in Indiana: Tax Reciprocity

State reciprocity

Does Ohio have a reciprocity agreement with Indiana?

Yes. Ohio has reciprocity agreements with five states: Indiana, Kentucky, Michigan, Pennsylvania and West Virginia. The agreement covers wages, salaries, tips and commissions. If you are a full-year Indiana resident and your only Ohio income is W-2 wages, you are exempt from Ohio state income tax. You file and pay state tax only in Indiana.

Reciprocity applies strictly to employee compensation. It does not cover self-employment income, rental income, gambling winnings or other non-wage Ohio-source income. If you earn any of those income types from Ohio, you must file an Ohio return and pay Ohio tax on that portion.

The agreement means Indiana residents working across the border avoid dual state-level taxation entirely on their wages. Ohio does not tax those wages, and Indiana taxes them at the flat 2.95% state rate for tax year 2026, plus county income tax based on your Indiana residence. Without reciprocity, you would need to file in both states and claim credits to avoid double taxation.

Filing obligations

Which tax returns do I file as an Indiana resident working in Ohio?

Because reciprocity covers your wages, you do not need to file an Ohio state return at all if wages are your only Ohio income. Your Indiana Form IT-40 handles both state and county tax in a single filing.

If you work in an Ohio city that levies a municipal income tax, you will also need to file a local return with that city or its designated tax administrator. Ohio municipal taxes are separate from the state. Many cities use the Regional Income Tax Agency (RITA) or the Central Collection Agency (CCA) for collection and filing.

File your Indiana return by April 15. In most reciprocity cases, there is nothing to calculate on the Ohio side at the state level.

Ohio local taxes

How does Ohio municipal income tax affect Indiana commuters?

Ohio's reciprocity agreement exempts you from state income tax, but it does not exempt you from Ohio municipal (city) income taxes. Most Ohio cities and villages levy their own local income tax, and that tax applies to anyone who earns income within the city limits, including nonresidents from other states.

Ohio municipal income tax rates range from 0% to 3.0% depending on the city; 1% is the most common rate. Columbus, for example, levies a 2.5% city income tax on all wages earned within city limits. Your Ohio employer typically withholds the applicable city tax from your paycheck automatically.

This local tax layer is the main surprise for Indiana residents working in Ohio. State reciprocity makes the state-level picture simple, but the city tax adds an extra obligation. Check the specific rate for the Ohio city where your workplace is located. The rate depends on the work location, not your home address.

Indiana does not provide a state-level credit for Ohio municipal taxes paid. The Ohio city tax is a separate cost of working across the border. Some Indiana residents who work in smaller Ohio towns or unincorporated areas may not face any city tax at all, since not every location in Ohio levies one.

Withholding setup

How do I set up reciprocity withholding with my Ohio employer?

1. Obtain Ohio Form IT-4NR from the Ohio Department of Taxation website or your employer's HR department. The form's official title is Employee's Statement of Residency in a Reciprocity State.
2. Complete the form, certifying that you are an Indiana resident. You will need your full name, Social Security number and Indiana home address.
3. Submit to your employer's payroll department. Once on file, your employer stops withholding Ohio state income tax from your wages.
4. Provide Indiana Form WH-4 so your employer can calculate the correct Indiana state and county withholding amounts.
5. Verify your pay stub after the next pay cycle. Confirm it shows Indiana state withholding, Indiana county withholding, zero Ohio state withholding, and the applicable Ohio city tax withholding (if any).

Your employer is required to keep IT-4NR on file for every employee who is a resident of a reciprocal state. If you change your residence from Indiana to a non-reciprocal state, you must notify your employer within 10 days.

Wrong withholding

What if my Ohio employer already withheld Ohio state tax?

If your employer withheld Ohio state income tax before you filed IT-4NR, you need to recover that money:

1. File IT-4NR immediately to stop further Ohio state withholding going forward.
2. Ask payroll about a mid-year correction. Some employers can reverse the Ohio withholding and redirect it to Indiana.
3. At year-end, file an Ohio IT-1040 as a nonresident, showing zero Ohio-taxable wages under reciprocity. Claim a full refund of the Ohio state withholding.
4. File your Indiana IT-40 and pay any Indiana state and county tax that was under-withheld during the period your employer was sending money to Ohio.

Do not claim the mistakenly withheld Ohio tax as a credit on your Indiana return. Indiana does not grant resident credits for tax paid to a reciprocal state. Instead, recover it directly from Ohio by filing the Ohio return.

To avoid this entirely, submit IT-4NR on your first day of employment or as soon as you begin working in Ohio.

Indiana county tax

What about Indiana county income tax?

All 92 Indiana counties levy a county income tax. As an Indiana resident, you owe county tax based on your county of residence, regardless of where you work. This tax is calculated on your Indiana adjusted gross income and is reported on your Indiana IT-40 return.

For 2026, county rates range from 0.5% (Porter County) to 3.0% (Randolph County). The rate that applies is determined by your county of residence on January 1 of the tax year. Even if you move counties on January 2, the January 1 county rate applies for the full calendar year.

Your employer should withhold Indiana county tax from your paycheck based on the county code you provide on Indiana Form WH-4. If your Ohio employer has set up reciprocity withholding correctly, they will withhold both Indiana state tax and your county tax. Verify your pay stub to confirm the correct county rate is being applied.

County tax rates can change in January or October of any year. Check the Indiana Department of Revenue's Departmental Notice #1 for the current rate schedule.

Remote work

Does reciprocity apply if I work remotely from Indiana?

Yes. If you are an Indiana resident employed by an Ohio company and you work from home in Indiana, reciprocity still covers your wages. You owe Indiana state and county tax only. Ohio does not tax remote wages earned by a resident of a reciprocal state working from their home state.

The practical effect: when you work entirely from Indiana, your Ohio municipal tax obligation drops to zero because you are no longer earning income within an Ohio city's limits. Your Indiana tax stays the same regardless of whether you commute or work remotely.

For hybrid schedules where you split time between an Ohio office and your Indiana home, only the days physically worked in Ohio generate Ohio municipal tax liability. Keep a log of your work location if your schedule varies. The Ohio city tax is based on where you perform the work, not where your employer is headquartered.

Mid-year moves

What if I moved between Ohio and Indiana during the year?

If you changed your state of residence during the tax year, file as a part-year resident in each state. For the months you lived in Ohio, file Ohio IT-1040 as a part-year resident and pay Ohio state tax on income earned during that period. After establishing Indiana residency, the reciprocity agreement applies for the remainder of the year.

File Indiana IT-40 as a part-year resident for the Indiana portion. Each state prorates income based on residency dates. Document your exact move date carefully, as both states require it. Indiana county tax status is set by your county of residence on January 1, so a mid-year move can shift your county assignment for the following year but not the current one.
