Live in Indiana, Work in Connecticut: Which State Taxes Your Paycheck?
Answer
Two returns, one credit. Connecticut has the first claim on wages earned inside the state and withholds accordingly. Indiana then taxes you as a resident on everything and gives credit for what Connecticut already took, capped at what Indiana would have charged on that same income.

Two states can lawfully tax the same wages: Connecticut because the work happened there, Indiana because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Indiana return, through the credit for taxes paid to another state.
A Indiana resident taxed by another state on the same income claims the credit for taxes paid to other states on Schedule 6 (Form IT-40PNR). The credit is capped at the Indiana 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 · ConnecticutForm CT-1040NR/PY
File the Connecticut nonresident return FIRST — you need the Connecticut tax figure before you can complete Indiana.
- 2Resident return · IndianaSchedule 6 (Form IT-40PNR)
File a Indiana resident return reporting all income, then claim the credit for tax paid to Connecticut. The credit is capped at what Indiana 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 Indiana and work in Connecticut. Which state takes the tax out of my paycheck?
Two returns, one credit. Connecticut has the first claim on wages earned inside the state and withholds accordingly. Indiana then taxes you as a resident on everything and gives credit for what Connecticut already took, capped at what Indiana would have charged on that same income.
Which state should my employer be withholding for?
Connecticut. The wages are sourced to Connecticut, so Connecticut withholding is correct and there is no Indiana 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. Indiana gives residents a credit for tax paid to Connecticut on the same income, claimed on Schedule 6 (Form IT-40PNR). The credit is capped at the Indiana tax on that income, so if Connecticut taxes it more heavily the excess is not refunded by either state.
