Mississippi Code Title 27. Taxation and Finance § 27-19-153

Whenever any vehicle in excess of ten thousand (10,000) pounds, gross vehicle weight, apportioned vehicles, rental and commercial trailers and buses, which have been registered and the annual tax paid thereon shall be sold or transferred, the purchaser or transferee thereof shall not be liable for any further or additional tax for the period of time covered by the original privilege license unless the original license is surrendered and a replacement license issued therefor under the provisions of Section 27-19-71 of this article, or unless there be some change in the classification or gross weight of such vehicle. The provisions of this paragraph shall not apply to trailers and semitrailers subject to the tax levied in Section 27-19-18.

Provided, however, when any vehicle which has been registered by the State of Mississippi or any county or city, levee district, school or drainage district, or any other political subdivision thereof, shall be sold or transferred, the person selling the vehicle for the state or political subdivision thereof shall remove the license tag which was issued to the state or political subdivision thereof for the vehicle being sold, and the purchaser or transferee thereof shall have five (5) full working days, exclusive of the date of delivery, within which to register the vehicle in the proper classification and gross weight bracket and shall pay the privilege license tax required for the vehicle. Any purchaser or transferee failing or refusing to register a vehicle acquired from the state or political subdivision thereof shall be liable for the full annual privilege license tax, plus a penalty thereon as provided in Section 27-19-63.
