New Jersey does not have a separate Part-Year tax return. To file a part year return, you will need to determine which form to use - resident or nonresident.
According to the New Jersey instructions:
- If you moved out of or into New Jersey and have New Jersey source income while you lived in NJ, file your part year return on the resident return form (NJ-1040).
- If you moved into or out of New Jersey and had New Jersey source income while you were a nonresident of NJ, file a nonresident return (NJ-1040NR) to report your New Jersey source income.
- If you moved into or out of New Jersey and had New Jersey source income both before and after you moved, file both the resident return reporting your New Jersey source income while you lived in NJ and the nonresident return reporting your New Jersey source income while you were a Nonresident of the state.
Within the program, you cannot file both a resident and nonresident return for the same state on the same account. You can download one of the forms from the New Jersey website and file the return by mail.
