According to the Resident, Part-Year , and Nonresident filing instruction web-pages, you must file a return if:
- Your filing status is Single or Married Filing Seperate AND your gross income was at least $10,000
OR
- Your filing status is Married Filing Joint, Head of Household, or Qualifying Widow(er) AND your gross income was at least $20,000
New Jersey requires that married couples use the same filing status for their New Jersey return as they used on their federal return. An exception to this rule is if one spouse is a resident and the other is a nonresident of New Jersey. If this is the case, the resident may file a separate return.
New Jersey and Pennsylvania have a reciprocal agreement. Compensation paid to New Jersey residents employed in Pennsylvania is not subject to the Pennsylvania income tax. Compensation means salaries, wages, tips, fees, commissions, bonuses, and other remuneration received for services rendered as an employee.
