State tax filing

@re2boys great, thank you for the information. No business/rental in NJ, and only PA is listed in block 15 withholding state taxes so I think I'm set. I did look on the Reciprocity site and it says form NJ-165 should be filed with my employer. I don't specifically remember completing the form but since only PA is listed on my W-2 I assume that I did it (over 5 years ago). Does that make sense?
