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