Moved from Alaska to South Dakota Mid-Year: Which State Tax Returns Do You File?
Answer
Neither state wants a return. Alaska and South Dakota both levy no personal income tax, so changing residence between them has no state tax consequence at all: no part-year returns, no proration, and no state withholding to redirect.

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 Alaska nor South Dakota levies one.
What you file
There is nothing to file in either Alaska or South Dakota on these wages. Your federal return is unaffected — the federal government taxes the income whatever the states do.

How do I split my income between Alaska and South Dakota?
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 South Dakota return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
