Miss. Code § 19-5-23
The tax levy authorized by Section 19-5-21 shall not be imposed until the board of supervisors shall have published notice of its intention to levy same. Said notice shall be published once each week for three (3) consecutive weeks in some newspaper having a general circulation in such county, but not less than twenty-one (21) days, nor more than sixty (60) days, intervening between the time of the first notice and the meeting at which said board proposes to levy such tax. If, within the time of giving notice, twenty percent (20%) or fifteen hundred (1500), whichever is less, of the qualified electors of the district affected shall protest or file a petition against the levy of such tax, then such tax shall not be levied unless authorized by a majority of the qualified electors of such district voting at an election to be called and held for that purpose. The notice provided for herein shall only be required prior to the initial levy except when the board of supervisors intends to increase the levy over the amount shown in the initial notice.
