Live in Illinois, Work in Indiana: Which State Taxes Your Paycheck?
Answer
You file twice: Indiana first, then Illinois. There is no reciprocity agreement between these two states, so Indiana taxes the income where it was earned and Illinois taxes it again as resident income — with the resident credit removing the double charge rather than an exemption form preventing it.

Two states can lawfully tax the same wages: Indiana because the work happened there, Illinois because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Illinois return, through the credit for taxes paid to another state.
A Illinois resident taxed by another state on the same income claims the credit for taxes paid to other states on Schedule CR. The credit is capped at the Illinois tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
Indiana also has a layer below the state one, and it is the layer that survives every agreement: Every Indiana county levies its own income tax, and the reciprocal agreements do not cover it. A resident of a reciprocal state who works in Indiana still pays Indiana county tax on those wages.
What you file
- 1Nonresident return · IndianaForm IT-40PNR
File the Indiana nonresident return FIRST — you need the Indiana tax figure before you can complete Illinois.
- 2Resident return · IllinoisSchedule CR
File a Illinois resident return reporting all income, then claim the credit for tax paid to Indiana. The credit is capped at what Illinois would have charged on that same income, so if Indiana taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in Illinois and work in Indiana. Which state takes the tax out of my paycheck?
You file twice: Indiana first, then Illinois. There is no reciprocity agreement between these two states, so Indiana taxes the income where it was earned and Illinois taxes it again as resident income — with the resident credit removing the double charge rather than an exemption form preventing it.
Which state should my employer be withholding for?
Indiana. The wages are sourced to Indiana, so Indiana withholding is correct and there is no Illinois 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. Illinois gives residents a credit for tax paid to Indiana on the same income, claimed on Schedule CR. The credit is capped at the Illinois tax on that income, so if Indiana taxes it more heavily the excess is not refunded by either state.
