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

Without an agreement between Iowa and Oklahoma, the overlap is handled after the fact rather than prevented. That is why the filing order matters: the Oklahoma figure is an input to the Iowa return, so completing Iowa first means doing it twice.
A Iowa resident taxed by another state on the same income claims the credit for taxes paid to other states on Form IA 130. The credit is capped at the Iowa 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 · OklahomaForm 511-NR
File the Oklahoma nonresident return FIRST — you need the Oklahoma tax figure before you can complete Iowa.
- 2Resident return · IowaForm IA 130
File a Iowa resident return reporting all income, then claim the credit for tax paid to Oklahoma. The credit is capped at what Iowa would have charged on that same income, so if Oklahoma taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in Iowa and work in Oklahoma. Which state takes the tax out of my paycheck?
Both states tax the same wages, and a credit undoes the overlap. Oklahoma withholds as your work state and you file a Oklahoma nonresident return; Iowa taxes residents on all income, so you also file at home and claim the credit for tax paid to Oklahoma. File Oklahoma first.
Which state should my employer be withholding for?
Oklahoma. The wages are sourced to Oklahoma, so Oklahoma withholding is correct and there is no Iowa 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. Iowa gives residents a credit for tax paid to Oklahoma on the same income, claimed on Form IA 130. The credit is capped at the Iowa tax on that income, so if Oklahoma taxes it more heavily the excess is not refunded by either state.
