State Tax residency?

I live in New Jersey however 100% source of my income is from New York. For which state should I file my state taxes? My employer has been withdrawing New York state taxes from my paycheck. Also, with New York State taxes being higher than New Jersey - even if I file my NJ taxes, I won't owe NJ anything... Do I still need to file? I only rent and don't own a house in NJ. Thanks

1. I lived in NJ and worked in NYC. You will probably find that you owe taxes to both. Even though New York taxes are higher than New Jersey's, you will find that you really don't get full credit and that you will still owe NJ something. So to answer your question, yes you will have to file both.
2. You'll have to file in both states, NY as a non-resident and NJ as a resident.
