For all of 2007, I lived and worked in Suffolk County four days per week, and I lived in the Bronx three days per week (not working during those three days). My employer generated my w-2 form with non-resident status based on my working and living in Suffolk County for my emploment. My question is, am I, for new York City tax purposes, a full time resident of New York City or a part-time resident of New York City? Thank you very much, Nirlepa

By definition, you are a part-time resident of NY City.

The question is domicile. More than likely NYC will consider you a full time resident. What is your mailing address? Where do you pay rent? You can't be a part time resident for tax purposes, it is a lot like being pregnant, either you are or your not.
