You may be required to file a New Jersey income tax return if you were a full-year resident, a part-year resident, or a nonresident with income from New Jersey sources during the year. A full-year resident reports all income subject to New Jersey gross income tax. The income may be received from any source. A resident who files single or married/CU partner filing separately, and who has gross income of more than $10,000, is required to file a return. For taxpayers whose filing status is either married/CU couple filing joint return, head of household, or qualifying widow(er)/surviving CU partner, the minimum filing threshold is $20,000. A part-year resident
is subject to tax on income derived from all sources during his period of residency in New Jersey if his income for the entire year exceeds the filing threshold for his filing status. Similar filing requirements apply for nonresidents
