Mississippi Code Title 27. Taxation and Finance § 27-35-149

It shall be the duty of the board of supervisors in carrying out the provisions of Sections 27-35-143 through 27-35-147 to make such changes in assessments as will cause the taxes to be charged to the person or property liable therefor, and to fix the assessments of property according to the true value thereof, to the end that all property shall be assessed and taxed equally and uniformly. In all cases, the board shall adopt an order and enter the same on its minutes, and shall show in its order the page and line of the assessment roll where such change or correction is made.

Upon receipt of the order (and application, if one be required), the clerk of the board of supervisors shall transmit a certified copy of the order to the tax collector of his county and shall file the application as a record in his office. No assessment shall be increased or decreased and no credit to or charge against the tax collector of any county on account of such increase or decrease shall be entered by the Auditor of Public Accounts or by the county auditor except as shown by an order adopted by the board of supervisors as provided herein. All changes in assessment made under the provisions hereof shall be entered on the proper line and page of the assessment roll in force, and the clerk and tax collector shall keep the proper record of all such changes, increases or decreases. Nothing in this and Sections 27-35-143 through 27-35-147 shall be construed to affect or modify any law with reference to the assessing of property which has escaped taxation in former years.
