Live in Ohio, Work in Iowa: Which State Taxes Your Paycheck?

Both states — credit offsets the double taxIowa withholds

Answer

Both states tax the same wages, and a credit undoes the overlap. Iowa withholds as your work state and you file a Iowa nonresident return; Ohio taxes residents on all income, so you also file at home and claim the credit for tax paid to Iowa. File Iowa first.

Two states can lawfully tax the same wages: Iowa because the work happened there, Ohio because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Ohio return, through the credit for taxes paid to another state.

A Ohio resident taxed by another state on the same income claims the credit for taxes paid to other states on Ohio Schedule of Credits (resident credit). The credit is capped at the Ohio tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.

Iowa also has a layer below the state one, and it is the layer that survives every agreement: Many Iowa school districts levy a surtax calculated as a percentage of state income tax. It is reported on the state return rather than separately.

What you file

  1. 1Nonresident return · IowaForm IA 1040 with Schedule IA 126

    File the Iowa nonresident return FIRST — you need the Iowa tax figure before you can complete Ohio.

  2. 2Resident return · OhioOhio Schedule of Credits (resident credit)

    File a Ohio resident return reporting all income, then claim the credit for tax paid to Iowa. The credit is capped at what Ohio would have charged on that same income, so if Iowa taxes it at a higher rate the difference is not refunded.

Same two states, different situation

The withholding answer turns on how you are paid and where the work happens, not only on which two states are involved.

Questions people actually ask

I live in Ohio and work in Iowa. Which state takes the tax out of my paycheck?

Both states tax the same wages, and a credit undoes the overlap. Iowa withholds as your work state and you file a Iowa nonresident return; Ohio taxes residents on all income, so you also file at home and claim the credit for tax paid to Iowa. File Iowa first.

Which state should my employer be withholding for?

Iowa. The wages are sourced to Iowa, so Iowa withholding is correct and there is no Ohio withholding to set up.

Will I end up paying tax twice on the same income?

Not twice over, but you will pay the higher of the two rates. Ohio gives residents a credit for tax paid to Iowa on the same income, claimed on Ohio Schedule of Credits (resident credit). The credit is capped at the Ohio tax on that income, so if Iowa taxes it more heavily the excess is not refunded by either state.
