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

Without an agreement between Ohio and Illinois, the overlap is handled after the fact rather than prevented. That is why the filing order matters: the Illinois figure is an input to the Ohio return, so completing Ohio first means doing it twice.
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.
What you file
- 1Nonresident return · IllinoisForm IL-1040 with Schedule NR
File the Illinois nonresident return FIRST — you need the Illinois tax figure before you can complete Ohio.
- 2Resident return · OhioOhio Schedule of Credits (resident credit)
File a Ohio resident return reporting all income, then claim the credit for tax paid to Illinois. The credit is capped at what Ohio would have charged on that same income, so if Illinois taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in Ohio and work in Illinois. Which state takes the tax out of my paycheck?
Illinois withholds and Ohio credits. Without an agreement between them, both states are entitled to tax income earned in Illinois by a Ohio resident. The mechanism that stops you paying twice is the credit on the Ohio resident return, which is why the Illinois return has to be completed first.
Which state should my employer be withholding for?
Illinois. The wages are sourced to Illinois, so Illinois 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 Illinois 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 Illinois taxes it more heavily the excess is not refunded by either state.
