Moved from Florida to Idaho Mid-Year: Which State Tax Returns Do You File?
Answer
Idaho taxes the second half of the year. Florida has no personal income tax, so the pre-move income is untouched at state level; the Idaho part-year return picks up from the date you became a Idaho resident and prorates your deductions to that stretch.

This move takes you into the state income tax system rather than out of it. Florida asked nothing of you; Idaho does, from the date your residency there begins.

Questions people actually ask
I moved from Florida to Idaho mid-year. Do I have to file in both states?
Idaho taxes the second half of the year. Florida has no personal income tax, so the pre-move income is untouched at state level; the Idaho part-year return picks up from the date you became a Idaho resident and prorates your deductions to that stretch.
How do I split my income between Florida and Idaho?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Florida resident belongs on the Florida return and income received afterwards on the Idaho return. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
