We live in NJ, but my wife works in Philadelphia. Her employer did not withhold NJ state taxes. They only withheld PA income taxes. I am going to file a PA return to request a refund for all of the state taxes paid to PA. I also added her state wages to our NJ return to pay taxes that are owed to NJ. She also paid Philadelphia wage tax. How do I go about getting credit for these taxes? I believe I can add it to the NJ state tax return. Do I include anything in "Double-taxed income while a resident of NJ"? I believe the answer is no in this situation.
