Moved from Massachusetts to Alaska Mid-Year: Which State Tax Returns Do You File?
Answer
Only the state you left wants a return. Massachusetts taxes the part of the year you lived there and prorates your deductions to that period. Alaska has no income tax, so the income you receive after the move faces no state tax at all.

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

Questions people actually ask
I moved from Massachusetts to Alaska mid-year. Do I have to file in both states?
Only the state you left wants a return. Massachusetts taxes the part of the year you lived there and prorates your deductions to that period. Alaska has no income tax, so the income you receive after the move faces no state tax at all.
How do I split my income between Massachusetts and Alaska?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Massachusetts resident belongs on the Massachusetts return and income received afterwards on the Alaska return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
