Miss. Code § 27-61-33
In the event that any taxes or penalties imposed by this chapter have been erroneously or illegally collected from any person, the commission may permit such person to take credit against a subsequent tax report for the amount of the erroneous payment, or the amount may be refunded to the person in the same manner as provided in Section 27-55-19. 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 chapter shall be construed to prohibit a refund or credit for tax paid on fuel tax reports not subject to tax or which is exempt from tax, provided there has not been a willful disregard of the provisions of this chapter and further provided that the claim is filed within three (3) years.
