Moved from Oregon to Alaska Mid-Year: Which State Tax Returns Do You File?

The clean part of this move is that only one return follows it. The part that catches people is the withholding: Oregon tax should stop when your residency does, and it often does not without a prompt.

Questions people actually ask
I moved from Oregon to Alaska mid-year. Do I have to file in both states?
Alaska asks for nothing. Your last state return is the Oregon part-year return covering the months before you moved; after that date Oregon has no claim on income from outside the state, and Alaska has no personal income tax to impose.
How do I split my income between Oregon and Alaska?
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 Alaska return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
