Moved from Ohio to South Dakota Mid-Year: Which State Tax Returns Do You File?
Answer
Ohio once, and then nothing. Because South Dakota does not tax personal income, this move takes you out of the state income tax system entirely. File the Ohio part-year return for the pre-move income and make sure Ohio withholding actually stopped when you left.
