Moved from Maine to Iowa Mid-Year: Which State Tax Returns Do You File?
Answer
Maine for the first part of the year, Iowa for the rest. Each state's part-year return reports the income received during that state's residency period and prorates the standard deduction, exemptions and credits accordingly. Keep evidence of the date you actually changed domicile.

A mid-year move splits the tax year in two, and each state taxes its own half. That is a residency question, so the machinery that governs commuters — reciprocity agreements, convenience rules, nonresident withholding — is beside the point here.

The other direction

Same two states, different situation
The withholding answer turns on how you are paid and where the work happens, not only on which two states are involved.
- W-2 commuter: Maine → IowaBoth states — credit offsets the double tax
- Remote worker: Maine → IowaHome state only
- 1099 contractor: Maine → IowaHome state, plus the client state if you work there

Questions people actually ask
I moved from Maine to Iowa mid-year. Do I have to file in both states?
Maine for the first part of the year, Iowa for the rest. Each state's part-year return reports the income received during that state's residency period and prorates the standard deduction, exemptions and credits accordingly. Keep evidence of the date you actually changed domicile.
How do I split my income between Maine and Iowa?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Maine resident belongs on the Maine return and income received afterwards on the Iowa return, with each state prorating your deductions, exemptions and credits to its own part of the year. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
