Miss. Code § 27-59-319
In the event that any taxes or penalties imposed by this article have been erroneously or illegally collected from a permittee or any other person, the commission may allow such permittee or other person to take credit against a subsequent tax report for the amount of the erroneous overpayment or the amount thereof may be refunded in the same manner as provided in Section 27-55-19, Mississippi Code of 1972.
No refunds shall be made under the provisions of this section unless a written claim is filed setting forth the circumstances by reason of which such refund should be allowed. Such claim shall be in such form as the commission shall prescribe, and shall be filed with the commission within three (3) years from the date of payment of the taxes erroneously or illegally collected. Nothing in this article shall be construed to prohibit a refund or credit for taxes paid, provided there has not been a willful disregard of the provisions of this article, and further provided that the claim therefor is filed within three (3) years.
