Live in Idaho, Work in Ohio: Which State Taxes Your Paycheck?
Answer
Ohio withholds and Idaho credits. Without an agreement between them, both states are entitled to tax income earned in Ohio by a Idaho resident. The mechanism that stops you paying twice is the credit on the Idaho resident return, which is why the Ohio return has to be completed first.

Without an agreement between Idaho and Ohio, the overlap is handled after the fact rather than prevented. That is why the filing order matters: the Ohio figure is an input to the Idaho return, so completing Idaho first means doing it twice.
A Idaho resident taxed by another state on the same income claims the credit for taxes paid to other states on Form 39NR. The credit is capped at the Idaho tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
Ohio also has a layer below the state one, and it is the layer that survives every agreement: Ohio has the densest local income tax in the country: several hundred municipalities levy a municipal income tax, and many school districts levy their own on top. Neither is covered by the reciprocal agreements. A Pennsylvania resident working in Columbus pays no Ohio state tax and full Columbus city tax.
What you file
- 1Nonresident return · OhioForm IT 1040 with Schedule IT NRC
File the Ohio nonresident return FIRST — you need the Ohio tax figure before you can complete Idaho.
- 2Resident return · IdahoForm 39NR
File a Idaho resident return reporting all income, then claim the credit for tax paid to Ohio. The credit is capped at what Idaho would have charged on that same income, so if Ohio taxes it at a higher rate the difference is not refunded.

- 1099 contractor: Idaho → OhioHome state, plus the client state if you work there
- Moved mid-year: Idaho → OhioTwo part-year returns

Questions people actually ask
I live in Idaho and work in Ohio. Which state takes the tax out of my paycheck?
Ohio withholds and Idaho credits. Without an agreement between them, both states are entitled to tax income earned in Ohio by a Idaho resident. The mechanism that stops you paying twice is the credit on the Idaho resident return, which is why the Ohio return has to be completed first.
Which state should my employer be withholding for?
Ohio. The wages are sourced to Ohio, so Ohio withholding is correct and there is no Idaho 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. Idaho gives residents a credit for tax paid to Ohio on the same income, claimed on Form 39NR. The credit is capped at the Idaho tax on that income, so if Ohio taxes it more heavily the excess is not refunded by either state.
