Moved from New Jersey to North Dakota Mid-Year: Which State Tax Returns Do You File?
Answer
New Jersey for the first part of the year, North Dakota 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 New Jersey to North Dakota mid-year. Do I have to file in both states?
New Jersey for the first part of the year, North Dakota 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 New Jersey and North Dakota?
By when you received it, measured against the date your domicile actually changed. Income received while you were a New Jersey resident belongs on the New Jersey return and income received afterwards on the North Dakota 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.
