I MOVED TO NY from NJ in 2013 and in 2014 lived in NY molst of the time. But i still have a house partially rented in NJ that i own and bunch of biklls still come to that address and i spent some amount of time there as well. This year when i was doing my taxes My accountant filed my taxes as if i am a resident of NJ and i only discoved it today. 1. I am assuming that by filing in NJ i get a tax break as NJ has no city tax. What was my savings on all in all of filing in NJ vs NY? Lets say my salary was 100000. 2. What are the ways i can mitigatge the situation in this case - refile the taxes? I still have bills that go to my NJ residence and i would have to pay again and its a drag. What are the consequencies of not refiling and leaving it loike that?
