Miss. Code Ann. § 27-9-41: Miss. Code Ann. § 27-9-41

(1) No final account of an executor shall be allowed by any court unless such account shows, and the judge of said court finds, that all taxes imposed by the provisions of this chapter upon said executor which have become payable, have been paid. The certificate of the commissioner and the receipt for the amount of the tax therein certified, which must become a part of the court record, shall be conclusive as to the payment of the tax to the extent of said certificate.

(2) For the purpose of facilitating the settlement and distribution of estates held by executors, the commissioner, with the approval of the attorney general may, on behalf of the state, agree upon the amount of taxes at any time due or to become due from such executor under the provisions of this chapter, and payment in accordance with such agreement shall be full satisfaction of the taxes to which the agreement relates.
