Moved from North Carolina to Massachusetts Mid-Year: Which State Tax Returns Do You File?

Two part-year returnsBoth states claim the income

Answer

North Carolina for the first part of the year, Massachusetts for the rest. Each state's part-year return reports the income received during that state's residency period and prorates the standard deduction, exemptions and credits accordingly. Keep evidence of the date you actually changed domicile.

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 North Carolina to Massachusetts mid-year. Do I have to file in both states?

North Carolina for the first part of the year, Massachusetts for the rest. Each state's part-year return reports the income received during that state's residency period and prorates the standard deduction, exemptions and credits accordingly. Keep evidence of the date you actually changed domicile.

How do I split my income between North Carolina and Massachusetts?

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 Massachusetts 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.
