Why am I considered a nonresident of NY and a nonresident of MA ? I lived in MA for 9 months

Well, I know this sounds funny but did you live in another state?  No, it depends on how you answered questions in the interview segment of the Federal return.  It asks if you moved during the tax year and you have to answer that question yes and name the state and date of residence change.

Is it possible that you earned MA income while residing in NY and NY income while residing in MA?  You are typically a Nonresident of a state for tax purposes if you did not live in that state at any time during the tax year, but you did receive income that is sourced from that state.

I suggest you go back into the Federal Return or better the My Info segment of the return to review your answers. Use the link below for additional information.

Multiple States

Your facts have changed from your earlier post.  Please read that answer to see if that helps.

Be careful how you answer the interview questions.  If your permanent home was in state A, and then you moved to state B and changed your permanent home, then you would be a part-year resident of state A and a part-year resident of state B.  

However, it is also possible that your permanent residence was in state A for the whole year, but you temporarily lived and worked in state B.  You would be a resident of state A and a non-resident of state B.  Or, a person might live half the year in state A and half the year in state B, but be a permanent resident of state C.  In this case they would be a resident of state C and non-residents of states A and B.  Your permanent residence or domicile is your main home, where you have significant family, personal and business ties.  There is no particular time limit.   It is possible to live and work temporarily in other states, even for years, but maintain a domicile somewhere else. It depends on the facts and circumstances.
