Mississippi law does not provide for a cash refund when a vehicle is sold, but it does provide for a credit to be used against the purchase of another tag. The tag from the car that was sold has to be turned in. Credit is given from the first of the next month following the date of surrender. A credit certificate can be given if not purchasing a new tag the same month. Credit can only be given from the time the tag is turned in not from when the vehicle was sold.
