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

This move takes you into the state income tax system rather than out of it. Alaska asked nothing of you; Wisconsin does, from the date your residency there begins.

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