Mississippi Code Title 27. Taxation and Finance § 27-69-21

(1) The provisions of this chapter shall not apply to any tobacco donated to any charitable organization for the use of inmates of any institution supported, in whole or in part, by donations from the public, nor shall its provisions apply to tobacco purchased by the state or federal government for use of inmates of any state or federal institution. This exemption from the payment of the tax can only be allowed by the commissioner on sales supported by proof that such taxable tobacco was not purchased for resale, but donated to the inmates of the institution claiming such exemption. This proof must be accompanied by an exemption claim form as prescribed by the commissioner and signed under penalty of perjury by an official of the institution requesting the exemption.

(2) It is further provided that no tax shall apply on sales of tobacco by a wholesaler or distributor to a retailer for resale on the Mississippi and Tennessee Rivers at midstream or in the intercoastal waterway in the Mississippi Sound to crew members for use or consumption on boats or barges transporting property in interstate commerce.
