Moved from Delaware to Alaska Mid-Year: Which State Tax Returns Do You File?
Answer
Delaware once, and then nothing. Because Alaska does not tax personal income, this move takes you out of the state income tax system entirely. File the Delaware part-year return for the pre-move income and make sure Delaware withholding actually stopped when you left.
