1099 Contractor in Pennsylvania with a New Jersey Client: Where Do You File?
Answer
The client's location does not decide this. Self-employment income from personal services is sourced to where the work happens, so working from Pennsylvania keeps it Pennsylvania-source and Pennsylvania-taxed. Travel to New Jersey to work and that portion becomes New Jersey-source, needing a New Jersey nonresident return.

Reciprocity agreements are the first thing contractors ask about and the first thing that does not apply to them. Every agreement in the country is a wage-withholding arrangement, and a 1099 has no withholding to switch off.
New Jersey publishes no de minimis day count or dollar floor for nonresidents. Any New Jersey-source wage income above the state's general filing threshold requires a nonresident return, and that threshold is reset each year — check the current figure on the New Jersey Division of Taxation nonresident instructions before filing.

Questions people actually ask
I live in Pennsylvania and my client is in New Jersey. Do I have to file a New Jersey tax return?

Self-employment income from personal services is sourced to where the work happens, so working from Pennsylvania keeps it Pennsylvania-source and Pennsylvania-taxed. Travel to New Jersey to work and that portion becomes New Jersey-source, needing a New Jersey nonresident return.
Do reciprocity agreements help a 1099 contractor?
No. Every state reciprocity agreement in the country is an arrangement about wage withholding between two revenue departments, and a 1099 has no withholding to switch off. Whether Pennsylvania and New Jersey hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
