Live in Ohio, Work in Connecticut: Which State Taxes Your Paycheck?
Answer
Both states tax the same wages, and a credit undoes the overlap. Connecticut withholds as your work state and you file a Connecticut nonresident return; Ohio taxes residents on all income, so you also file at home and claim the credit for tax paid to Connecticut. File Connecticut first.

Without an agreement between Ohio and Connecticut, the overlap is handled after the fact rather than prevented. That is why the filing order matters: the Connecticut 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

File the Connecticut nonresident return FIRST — you need the Connecticut 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 Connecticut. The credit is capped at what Ohio would have charged on that same income, so if Connecticut taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in Ohio and work in Connecticut. Which state takes the tax out of my paycheck?
Both states tax the same wages, and a credit undoes the overlap. Connecticut withholds as your work state and you file a Connecticut nonresident return; Ohio taxes residents on all income, so you also file at home and claim the credit for tax paid to Connecticut. File Connecticut first.
Which state should my employer be withholding for?
Connecticut. The wages are sourced to Connecticut, so Connecticut 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 Connecticut 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 Connecticut taxes it more heavily the excess is not refunded by either state.
