Miss. Code § 91-7-277
Every executor or administrator, at least once in each year or oftener if required by the court, shall present under oath an account of his administration, showing the disbursements, every item of which and the amount thereof to be distinctly stated, and it shall also show the receipts of money and from what sources. The failure to account annually shall be a breach of the administration bond, for which it may be put in suit, or the executor or administrator may be removed; but the court may, on application and on cause shown, extend the time for accounting. The court shall examine all such accounts and if satisfied that the account is just and true, it shall decree the same approved and allowed as a correct annual settlement.
There shall be no requirement for filing annual accounts if the requirement of filing accountings is waived in the testator's will. The court or the chancellor may also waive the requirement for filing annual accounts in an intestate estate upon petition to the court by the administrator. Even though the requirement of filing annual accounts is waived in the testator's will or waived by the court or the chancellor upon petition to the court by the administrator in an intestate estate, the court or the chancellor may later order the executor or administrator to file annual accounts upon the petition of a beneficiary or other interested party if the court or the chancellor determines that the filing of annual accounts is necessary or advisable.
