I have a client who worked in Philly and came in with a W2 with NJ withholding and Philly city tax withheld. I understand there is a reciprocal agreement but any NJ/PA folks out there with any friendly advice on how this works?

My thought is that I need to do a NJ return to get the witholding back and then a PA return without the withholding....

Apologies, don't see many NJ/PA returns out west.
