Moved from Oregon to Maine Mid-Year: Which State Tax Returns Do You File?
Answer
Oregon for the first part of the year, Maine for the rest. Each state's part-year return reports the income received during that state's residency period and prorates the standard deduction, exemptions and credits accordingly. Keep evidence of the date you actually changed domicile.

A mid-year move splits the tax year in two, and each state taxes its own half. That is a residency question, so the machinery that governs commuters — reciprocity agreements, convenience rules, nonresident withholding — is beside the point here.
What you file
- 1Part-year return · OregonForm OR-40-P
File a Oregon part-year return covering the months you lived in Oregon. A part-year resident of Oregon reports the income received while a Oregon resident, plus any Oregon-source income received during the rest of the year, and prorates the deductions and credits to the residency period.

File a Maine part-year return covering the months you lived in Maine. A part-year resident of Maine reports the income received while a Maine resident, plus any Maine-source income received during the rest of the year, and prorates the deductions and credits to the residency period.

The other direction
Reversing the commute does not always reverse the answer. Living in Maine and working in Oregon gives:Two part-year returns.
Same two states, different situation
The withholding answer turns on how you are paid and where the work happens, not only on which two states are involved.
- W-2 commuter: Oregon → MaineBoth states — credit offsets the double tax
- Remote worker: Oregon → MaineHome state only
- 1099 contractor: Oregon → MaineHome state, plus the client state if you work there

Questions people actually ask
I moved from Oregon to Maine mid-year. Do I have to file in both states?
Oregon for the first part of the year, Maine for the rest. Each state's part-year return reports the income received during that state's residency period and prorates the standard deduction, exemptions and credits accordingly. Keep evidence of the date you actually changed domicile.
How do I split my income between Oregon and Maine?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Oregon resident belongs on the Oregon return and income received afterwards on the Maine return, with each state prorating your deductions, exemptions and credits to its own part of the year. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
