Moved from North Carolina to Delaware Mid-Year: Which State Tax Returns Do You File?
Answer
You file two part-year returns. North Carolina taxes the income you received while you lived there, Delaware 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.

A mid-year move splits the tax year in two, and each state taxes its own half. That is a residency question, so the machinery that governs commuters — reciprocity agreements, convenience rules, nonresident withholding — is beside the point here.

- Remote worker: North Carolina → DelawareConvenience-of-the-employer rule — both states tax you

Questions people actually ask
I moved from North Carolina to Delaware mid-year. Do I have to file in both states?
You file two part-year returns. North Carolina taxes the income you received while you lived there, Delaware 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 North Carolina and Delaware?
By when you received it, measured against the date your domicile actually changed. Income received while you were a North Carolina resident belongs on the North Carolina return and income received afterwards on the Delaware 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.
