Two things catch people out. Mississippi gives zero credit for sales tax paid to another state on a vehicle, so buying out of state can mean paying twice. And a private sale is taxed on the Department of Revenue’s book value, not what you paid. A vehicle 10 or more years past manufacture is exempt in a private sale, as are transfers between close family.

This does not include manufacturer’s rebates. ... If you paid sales tax to another state, it will not be credited toward Mississippi tax when you register the vehicle.”
