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

Two states can lawfully tax the same wages: Oregon because the work happened there, Connecticut because you live there. Nothing prevents the overlap in advance — it is unwound afterwards, on the Connecticut return, through the credit for taxes paid to another state.
A Connecticut resident taxed by another state on the same income claims the credit for taxes paid to other states on Schedule 2 (Form CT-1040). The credit is capped at the Connecticut 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 Connecticut.
- 2Resident return · ConnecticutSchedule 2 (Form CT-1040)
File a Connecticut resident return reporting all income, then claim the credit for tax paid to Oregon. The credit is capped at what Connecticut would have charged on that same income, so if Oregon taxes it at a higher rate the difference is not refunded.

Same two states, different situation

- Remote worker: Connecticut → OregonHome state only
- 1099 contractor: Connecticut → OregonHome state, plus the client state if you work there
- Moved mid-year: Connecticut → OregonTwo part-year returns

Questions people actually ask
I live in Connecticut and work in Oregon. Which state takes the tax out of my paycheck?
Oregon withholds and Connecticut credits. Without an agreement between them, both states are entitled to tax income earned in Oregon by a Connecticut resident. The mechanism that stops you paying twice is the credit on the Connecticut 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 Connecticut 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. Connecticut gives residents a credit for tax paid to Oregon on the same income, claimed on Schedule 2 (Form CT-1040). The credit is capped at the Connecticut tax on that income, so if Oregon taxes it more heavily the excess is not refunded by either state.
