Moved from Iowa to Utah Mid-Year: Which State Tax Returns Do You File?
Answer
Both states want a return, but neither taxes the whole year. Moving from Iowa to Utah splits the tax year at the date your residency changed: a Iowa part-year return covers everything before it, a Utah part-year return everything after. Income is assigned by when it was received.

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.
What you file
- 1Part-year return · IowaForm IA 1040 with Schedule IA 126
File a Iowa part-year return covering the months you lived in Iowa. A part-year resident of Iowa reports the income received while a Iowa resident, plus any Iowa-source income received during the rest of the year, and prorates the deductions and credits to the residency period.
- 2Part-year return · UtahForm TC-40 with Schedule TC-40B
File a Utah part-year return covering the months you lived in Utah. A part-year resident of Utah reports the income received while a Utah resident, plus any Utah-source income received during the rest of the year, and prorates the deductions and credits to the residency period.

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: Iowa → UtahBoth states — credit offsets the double tax
- Remote worker: Iowa → UtahHome state only
- 1099 contractor: Iowa → UtahHome state, plus the client state if you work there

Questions people actually ask
I moved from Iowa to Utah mid-year. Do I have to file in both states?
Both states want a return, but neither taxes the whole year. Moving from Iowa to Utah splits the tax year at the date your residency changed: a Iowa part-year return covers everything before it, a Utah part-year return everything after. Income is assigned by when it was received.
How do I split my income between Iowa and Utah?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Iowa resident belongs on the Iowa return and income received afterwards on the Utah 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.
