In scanning all the groups, I see no one has asked about the NJ state income tax liability, if any, for 100% non-residents (never set foot in NJ) who are paid by NJ-based firms. I live in a non-income tax state, so state income tax credit is not part of the picture.
I am a 1099 worker for an NJ-based firm, though I have other clients. I work purely over the internet. In calling NJ Tax authorities, I get the answer that NJ source means NJ tax. But many postings over the internet say that various laws and court decisions are contrary to this. The experience of a knowledgeable person is appreciated.
Moderator: The source of your income is where you lived when you earned the income. But NJ may have different rules.
