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

Without an agreement between Arizona and Oregon, the overlap is handled after the fact rather than prevented. That is why the filing order matters: the Oregon figure is an input to the Arizona return, so completing Arizona first means doing it twice.
A Arizona resident taxed by another state on the same income claims the credit for taxes paid to other states on Form 309. The credit is capped at the Arizona tax on that income, so it removes the double tax but never refunds the excess when the other state charges more.
Oregon also has a layer below the state one, and it is the layer that survives every agreement: The Portland area layers two local income taxes on top of the state tax — the Metro supportive housing tax and the Multnomah County preschool tax — and both reach nonresidents on income sourced to the district. They are administered by the City of Portland Revenue Division, not the Department of Revenue.
What you file
- 1Nonresident return · OregonForm OR-40-N
File the Oregon nonresident return FIRST — you need the Oregon tax figure before you can complete Arizona.
- 2Resident return · ArizonaForm 309
File a Arizona resident return reporting all income, then claim the credit for tax paid to Oregon. The credit is capped at what Arizona would have charged on that same income, so if Oregon taxes it at a higher rate the difference is not refunded.

Questions people actually ask
I live in Arizona and work in Oregon. Which state takes the tax out of my paycheck?
Oregon withholds and Arizona credits. Without an agreement between them, both states are entitled to tax income earned in Oregon by a Arizona resident. The mechanism that stops you paying twice is the credit on the Arizona resident return, which is why the Oregon return has to be completed first.
Which state should my employer be withholding for?
Oregon. The wages are sourced to Oregon, so Oregon withholding is correct and there is no Arizona 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. Arizona gives residents a credit for tax paid to Oregon on the same income, claimed on Form 309. The credit is capped at the Arizona tax on that income, so if Oregon taxes it more heavily the excess is not refunded by either state.
