Moved from Rhode Island to Idaho 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 Rhode Island source can still pull a nonresident filing along with it.

Part-year returns are designed so that neither state taxes the whole year. The risk is not double taxation by default; it is misassigning income received near the move date, and losing the proration on deductions and credits.
What you file
- 1Part-year return · Rhode IslandForm RI-1040NR
File a Rhode Island part-year return covering the months you lived in Rhode Island. A part-year resident of Rhode Island reports the income received while a Rhode Island resident, plus any Rhode Island-source income received during the rest of the year, and prorates the deductions and credits to the residency period.
- 2Part-year return · IdahoForm 43 (part-year resident)
File a Idaho part-year return covering the months you lived in Idaho. A part-year resident of Idaho reports the income received while a Idaho resident, plus any Idaho-source income received during the rest of the year, and prorates the deductions and credits to the residency period.

Questions people actually ask
I moved from Rhode Island to Idaho 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 Rhode Island source can still pull a nonresident filing along with it.
How do I split my income between Rhode Island and Idaho?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Rhode Island resident belongs on the Rhode Island return and income received afterwards on the Idaho 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.
