Domicile Determination for NC State Tax
In addition to the day count, the NC Dept of Revenue also considers your domicile when determining residency for North Carolina income tax. Domicile is your fixed, permanent home to which you intend to return whenever absent. Factors that influence domicile include the location of your family, where you're registered to vote, where you maintain driver's licenses and vehicle registrations, and the address you use for bills and correspondence. Changing your domicile requires a clear demonstration of intent to establish a new permanent home outside of North Carolina, which can affect your state tax obligations.
