Tax Year Prior to 2020: If I lived 7 months in Florida and 5 months in NJ am I considered a Florida resident?

[KarenL2]

You are a part-year resident of each state if you moved.  

If you regularly live in both states, then your resident state is the state in which you have established a "permanent" residence.  To determine permanent residency, some things that would be considered are owning a home, where your driver's license is from, and where you are registered to vote.

If you made a permanent move to one state, then that is your permanent residence state, even if you haven't purchase property.  

If you have a second home in one of the states, then that state is the non-resident state.

How do I file if I move to a different state last year?
