Miss. Code § 19-9-111
The board of supervisors of any county authorized to establish or cooperate in the establishment of economic development districts pursuant to Section 19-5-99 may, in its discretion, levy a tax of not more than two (2) mills against the taxable property in the county or the portion thereof comprising an economic development district, to be used to support and maintain such district. The levy so made shall be in addition to all other levies provided by law.
Before any such levy is made, the board of supervisors shall signify its intention to make such a levy and publish same in a newspaper published in said county for thirty (30) days prior to making said levy. In the event more than twenty percent (20%) or fifteen hundred (1500), whichever is less, of the qualified electors of said economic development district protest in writing to the board of supervisors against the imposition of such tax levy within thirty (30) days from the date such notice is published, then such proposed tax levy shall not be made unless same is approved by a special election called for said purpose. Said special election shall be conducted and had as provided by law.
The governing authorities of any municipality in a county, which has established an economic development district or which is included in an economic development district, may contribute to the support of such economic development district from its general fund.
