Moved from New York to New Mexico Mid-Year: Which State Tax Returns Do You File?
Answer
Expect a part-year filing on each side. The point of a part-year return is that neither state taxes the whole year, so you are not double-taxed by default — but income received close to the move date has to be assigned carefully, and a lingering New York source can still pull a nonresident filing along with it.

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 · New YorkForm IT-203
File a New York part-year return covering the months you lived in New York. A part-year resident of New York reports the income received while a New York resident, plus any New York-source income received during the rest of the year, and prorates the deductions and credits to the residency period.
- 2Part-year return · New MexicoForm PIT-1 with Schedule PIT-B
File a New Mexico part-year return covering the months you lived in New Mexico. A part-year resident of New Mexico reports the income received while a New Mexico resident, plus any New Mexico-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 New Mexico and working in New York 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: New York → New MexicoBoth states — credit offsets the double tax
- Remote worker: New York → New MexicoHome state only
- 1099 contractor: New York → New MexicoHome state, plus the client state if you work there

Questions people actually ask
I moved from New York to New Mexico mid-year. Do I have to file in both states?
Expect a part-year filing on each side. The point of a part-year return is that neither state taxes the whole year, so you are not double-taxed by default — but income received close to the move date has to be assigned carefully, and a lingering New York source can still pull a nonresident filing along with it.
How do I split my income between New York and New Mexico?
By when you received it, measured against the date your domicile actually changed. Income received while you were a New York resident belongs on the New York return and income received afterwards on the New Mexico 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.
