Moved from Idaho to Texas Mid-Year: Which State Tax Returns Do You File?
Answer
A single part-year filing in Idaho. The move date closes your Idaho residency and, because Texas levies no income tax, opens nothing on the other side. Watch for a lingering Idaho source of income after the move — that would require a Idaho nonresident filing as well.

Moving to a state with no income tax ends your state filing obligation on the day your residency changes — but not a day earlier. Idaho taxes everything you received while you still lived there.

Questions people actually ask
I moved from Idaho to Texas mid-year. Do I have to file in both states?
A single part-year filing in Idaho. The move date closes your Idaho residency and, because Texas levies no income tax, opens nothing on the other side. Watch for a lingering Idaho source of income after the move — that would require a Idaho nonresident filing as well.
How do I split my income between Idaho and Texas?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Idaho resident belongs on the Idaho return and income received afterwards on the Texas return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
