If you are asking about residency status and how you should file your state return you can use this information as your guide.
Residency is determined by domicile and intent.
Simply put, your domicile is your home—the state you consider your permanent place of residence. If you aren't living there right now, then it's the place to which you intend to return and make your home indefinitely. You can have more than one residence, but only one domicile.
An individual may have many residences, or physical dwellings in which he resides, but can have only one domicile, or that permanent residence to which he intends to return. A review of states residency requirements show that 28 states use some definition of domicile to determine if a taxpayer is a resident.
