I'm just across the border from NC in SC. RV's are taxed as property tax and not vehicle tax like trucks/cars. NC is the same as us in that regard.
Not quite true:
I am looking at my TT bill that I just paid. The name of the form is " NC Combined Vehicle Registration Renewal and Property Tax". Cost are broken down as follows: 1- " Vehicle Property Tax Information" and 2-"Vehicle Registration / Inspection Information"
There are 2 amounts on the bill, " Property Tax" and Registration Fee"
So they actually call the tax a Vehicle Property Tax. It is now combined with State Registration and in order to renew a registration you have to pay the Personal Property / Vehicle Property tax at the same time.
Have no idea what they would or could do with out of State registered Vehicles, although I there is a DMV requirement if you move to NC that you register your vehicle in NC within 30 days of you current states expiration. So I guess it would depend on whether you are a " resident" of NC according to the State laws.
