Moved from Kansas to Alaska Mid-Year: Which State Tax Returns Do You File?
Answer
A single part-year filing in Kansas. The move date closes your Kansas residency and, because Alaska levies no income tax, opens nothing on the other side. Watch for a lingering Kansas source of income after the move — that would require a Kansas nonresident filing as well.

Moving to a state with no income tax ends your state filing obligation on the day your residency changes — but not a day earlier. Kansas taxes everything you received while you still lived there.

Questions people actually ask
I moved from Kansas to Alaska mid-year. Do I have to file in both states?
A single part-year filing in Kansas. The move date closes your Kansas residency and, because Alaska levies no income tax, opens nothing on the other side. Watch for a lingering Kansas source of income after the move — that would require a Kansas nonresident filing as well.
How do I split my income between Kansas and Alaska?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Kansas resident belongs on the Kansas return and income received afterwards on the Alaska return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
