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

I think you are a non-resident of NYC. Based on your description that you spent more time living in Suffolk County than NYC (eating, sleeping), I believe you clam Suffolk as your principal residence. Hence no NYC resident tax is due.
