Moved from Alaska to New Mexico Mid-Year: Which State Tax Returns Do You File?
Answer
One return, filed in New Mexico. Alaska levies no personal income tax, so nothing is due for the part of the year you lived there. A New Mexico part-year return covers the income you received after the move, with deductions and credits prorated to that period.

How do I split my income between Alaska and New Mexico?
