Mississippi Code
Article 1 - General Provisions
§ 27-59-47. Refund of taxes erroneously or illegally collected

In the event that any taxes, permit fees or penalties imposed by this chapter have been erroneously or illegally collected from a distributor or other person, the commission may, upon approval by the commission, permit such distributor or other person to take credit against a subsequent tax report for the amount of the erroneous overpayment, or may issue payment for that amount. The amount thereof may be refunded to the distributor or other 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. Said 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 or permit fees erroneously or illegally collected.
Nothing in this chapter shall be construed to prohibit a refund or credit for tax paid on liquefied compressed gas 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 provided this claim is filed within three (3) years.
