Moved from Ohio to Oregon Mid-Year: Which State Tax Returns Do You File?
Answer
You file two part-year returns. Ohio taxes the income you received while you lived there, Oregon taxes the income you received after the move, and each state prorates your deductions and credits to its own slice of the year. The date you changed domicile is the dividing line.

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.

Questions people actually ask
I moved from Ohio to Oregon mid-year. Do I have to file in both states?
You file two part-year returns. Ohio taxes the income you received while you lived there, Oregon taxes the income you received after the move, and each state prorates your deductions and credits to its own slice of the year. The date you changed domicile is the dividing line.
How do I split my income between Ohio and Oregon?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Ohio resident belongs on the Ohio return and income received afterwards on the Oregon 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.
