Mississippi law does not allow for a refund of registration fees or taxes. However, when the vehicle is sold or ownership changes, the owner may apply the unused portion of a registration to a new Mississippi registration. The tag from the vehicle that was sold must be turned in to the county Tax Collector. Credit is given from the first of the next month following the date of the tag’s surrender. A credit certificate will be given to you if you are not purchasing a new tag the same month. Credit can only be given from the time the tag is turned in, not from the time the vehicle was sold. You may use the credit certificate in any county of this state. Mississippi law does not provide for refunds when an individual moves out of state and cannot use the credit.
