Moved from Maine to California Mid-Year: Which State Tax Returns Do You File?
Answer
Both states want a return, but neither taxes the whole year. Moving from Maine to California splits the tax year at the date your residency changed: a Maine part-year return covers everything before it, a California 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 · MaineForm 1040ME with Schedule NRH
File a Maine part-year return covering the months you lived in Maine. A part-year resident of Maine reports the income received while a Maine resident, plus any Maine-source income received during the rest of the year, and prorates the deductions and credits to the residency period.
- 2Part-year return · CaliforniaForm 540NR (part-year resident)
File a California part-year return covering the months you lived in California. A part-year resident of California reports the income received while a California resident, plus any California-source income received during the rest of the year, and prorates the deductions and credits to the residency period.

The other direction
Reversing the commute does not always reverse the answer. Living in California and working in Maine gives:Two part-year returns.
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 → CaliforniaBoth states — credit offsets the double tax
- Remote worker: Maine → CaliforniaHome state only
- 1099 contractor: Maine → CaliforniaHome state, plus the client state if you work there

Questions people actually ask
I moved from Maine to California mid-year. Do I have to file in both states?
Both states want a return, but neither taxes the whole year. Moving from Maine to California splits the tax year at the date your residency changed: a Maine part-year return covers everything before it, a California part-year return everything after. Income is assigned by when it was received.
How do I split my income between Maine and California?
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 California 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.
