Mississippi Code Title 27. Taxation and Finance § 27-65-37

(1) If adequate records of the gross income or gross proceeds of sales are not maintained or invoices preserved as provided herein, or if an audit of the records of a taxpayer, or any return filed by him, or any other information discloses that taxes are due and unpaid, the commissioner shall make assessments of taxes, damages, and interest from any information available, which shall be prima facie correct. However, if in an audit of the records of a taxpayer it is determined that during the period being audited the taxpayer reported and paid tax in accordance with a method used during a prior period which had been audited by the commissioner and not found to result in any additional tax due, the commissioner shall be estopped from collecting any additional tax as a result of the use of this previously audited method for any period prior to notification by the commissioner or his agent during the current audit that use of the previously audited method would result in additional tax being due if it is determined, through all information available regarding this taxpayer, that:

(2) The commissioner shall give notice to the taxpayer of the assessments and demand payment of the tax, damages and interest within sixty (60) days from the date the commissioner mailed or hand delivered the notice. The notice shall be sent by regular first class mail or delivered by an agent of the commissioner. In the case of an individual, the notice shall be sent by mail to the taxpayer or delivered by an agent of the commissioner to the taxpayer, to a manager or general agent at the taxpayer's place of business or to someone above the age of sixteen (16) years at the taxpayer's residence. In the case of a partnership, the notice shall be sent by mail to the partnership or delivered by an agent of the commissioner to any partner, to a manager or general agent at the taxpayer's place of business or to someone above the age of sixteen (16) years at the residence of any partner. In the case of a corporation, limited liability company, joint venture, association, estate, trust or other group or combination acting as a unit, including any government entity, the notice shall be sent by mail to the taxpayer or delivered by an agent of the commissioner to an officer of the entity, to someone above the age of sixteen (16) years at the residence of an officer of the entity or to a manager or general agent at the taxpayer's place of business.

(3) If the taxpayer shall fail or refuse to comply with the notice of assessment or shall fail to petition for a hearing, the commissioner shall proceed as provided in Section 27-65-39.
