Moved from South Dakota to Alaska Mid-Year: Which State Tax Returns Do You File?
Answer
No state filing on either side of the move. Both South Dakota and Alaska are outside the state income tax system, so the date you changed domicile does not matter for tax purposes — though it may still matter for residency, voting and vehicle registration.

Residency still matters for plenty of things after a move like this — domicile, vehicle registration, in-state tuition — but state income tax is not among them, because neither South Dakota nor Alaska levies one.
What you file
There is nothing to file in either South Dakota or Alaska on these wages. Your federal return is unaffected — the federal government taxes the income whatever the states do.

Questions people actually ask
I moved from South Dakota to Alaska mid-year. Do I have to file in both states?
No state filing on either side of the move. Both South Dakota and Alaska are outside the state income tax system, so the date you changed domicile does not matter for tax purposes — though it may still matter for residency, voting and vehicle registration.
How do I split my income between South Dakota and Alaska?
By when you received it, measured against the date your domicile actually changed. Income received while you were a South Dakota resident belongs on the South Dakota return and income received afterwards on the Alaska return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
