Miss. Code § 21-33-45
The governing authorities of each municipality of this state shall, either at their regular meeting in September of each year or not later than ten (10) days after the final approval of the assessment rolls, levy the municipal ad valorem taxes for the fiscal year next succeeding, and shall, by resolution, fix the tax rate or levy for the municipality and for any other taxing districts of which the municipality may be a part. The rates or levies for the municipality or for any such taxing district shall be expressed in mills or a decimal fraction of a mill, which tax rates, or levies, shall determine the ad valorem taxes to be collected upon each dollar of valuation upon the assessment rolls of the municipality for municipal taxes, and to be collected upon each dollar of valuation as shown upon the assessment rolls of the municipality for each such taxing district, except as to such values as may be exempt, in whole or in part, from certain tax rates or levies. If the rates or levies for the municipality or taxing district are an increase from the previous fiscal year, then the proposed rate or levy increase shall be advertised in accordance with Section 27-39-203.
In making the levy of taxes, the governing authorities shall specify in such resolution the levy for each purpose as follows:
If the governing authorities of any municipality shall not levy the municipal taxes and the district taxes at its regular September meeting, such governing authorities shall levy the same at an adjourned or special meeting not later than ten (10) days after the final approval of the assessment rolls. However, that if such levy be not made on or before September 15 then road and bridge privilege tax license plates may be issued by the tax collector or Department of Revenue, as the case may be, for motor vehicles as defined in the Motor Vehicle Ad Valorem Tax Law of 1958 (Section 27-51-1 et seq.), without collecting or requiring proof of payment of municipal ad valorem taxes until such levy is duly certified to him, and for twenty-four (24) hours thereafter.
In the case of a municipality operating under a special or private charter providing for or authorizing the assessment, levying and collection of ad valorem taxes prior to October in each year, ad valorem taxes for such municipality shall be levied at the time prescribed or authorized by such special or private charter, unless the governing authority of such municipality by resolution adopted and spread of record in its minutes elect to levy ad valorem taxes at the time prescribed hereinbefore in this section. In any event, however, all ad valorem taxes levied by any municipality in this state, shall be levied in the manner required herein regardless of the time when such taxes are levied.
