New Jersey residents pay tax on income from all sources, but Schedule NJ-COJ can reduce double taxation when the same income was taxed by a qualifying outside jurisdiction. New Jersey–Pennsylvania wage reciprocity is different: Pennsylvania does not tax a New Jersey resident’s qualifying wages at the state level.
Key takeaways
- New Jersey says a resident’s out-of-state income remains subject to New Jersey Income Tax. Schedule NJ-COJ can apply when the same income was taxed by New Jersey and another qualifying jurisdiction, but the credit is limited.
- New Jersey explains that the Pennsylvania reciprocal agreement removes Pennsylvania state tax on New Jersey residents’ wages. It also says Pennsylvania municipal wage tax is a separate question.

Which return and records may be needed?
Retain every out-of-state nonresident return and W-2. For NJ-COJ, calculate the credit only for income taxed by both jurisdictions and follow the current instructions. Do not treat reciprocity as an automatic resident credit.

Why state residency and your federal tax home are different
A state return asks which state may tax income. The federal travel-nurse tax-home analysis asks whether you were away from a qualifying tax home and incurred duplicated living expenses. One label does not establish the other, so keep the records for each question separate.
See the travel nurse tax-home guide.
What to do before your first paycheck
- Separate Pennsylvania state withholding from Philadelphia or other municipal wage withholding.
- Retain completed nonresident returns before preparing NJ-COJ.
- Evaluate each assignment state separately; one may use reciprocity while another needs a credit.

FAQ
Can New Jersey nurses claim an out-of-state tax credit?
Possibly. NJ-COJ applies to qualifying income or wage tax paid to another jurisdiction on mutually taxed income.
Do New Jersey nurses pay Pennsylvania state tax on wages?
Under reciprocity, qualifying New Jersey residents employed in Pennsylvania do not pay Pennsylvania state income tax on those wages.
Do I need both NJ and nonresident returns?
You may. A New Jersey resident can need NJ-1040 plus an assignment-state nonresident return.
Does NJ-COJ refund every dollar of another state’s tax?
No. New Jersey limits the credit to the New Jersey tax attributable to the income.
