Moved from Alaska to Utah Mid-Year: Which State Tax Returns Do You File?
Answer
Utah taxes the second half of the year. Alaska has no personal income tax, so the pre-move income is untouched at state level; the Utah part-year return picks up from the date you became a Utah resident and prorates your deductions to that stretch.

Coming from a state with no income tax means arriving with no Utah withholding history and no prior-year liability to base estimates on. The first Utah return is where that catches up, so the withholding start date matters.

Questions people actually ask
I moved from Alaska to Utah mid-year. Do I have to file in both states?
Utah taxes the second half of the year. Alaska has no personal income tax, so the pre-move income is untouched at state level; the Utah part-year return picks up from the date you became a Utah resident and prorates your deductions to that stretch.
How do I split my income between Alaska and Utah?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Alaska resident belongs on the Alaska return and income received afterwards on the Utah return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
