Moved from Alaska to Louisiana Mid-Year: Which State Tax Returns Do You File?
Answer
A single part-year filing in Louisiana. Your former state asks for nothing, having no income tax to levy. Make sure your employer switched withholding to Louisiana at the right date — a late switch leaves a balance due on the Louisiana return.

Questions people actually ask

A single part-year filing in Louisiana. Your former state asks for nothing, having no income tax to levy. Make sure your employer switched withholding to Louisiana at the right date — a late switch leaves a balance due on the Louisiana return.
How do I split my income between Alaska and Louisiana?
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 Louisiana return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
