Ad valorem taxes of newly created municipalities or special districts shall be initially imposed no earlier than the January 1 subsequent to the creation or establishment of the municipality or district. The creation by a county of a municipal service taxing unit under s. 125.01 is not controlled by this section if the boundaries of the municipal service taxing unit conform to the boundaries of existing special districts, include all the unincorporated areas, or include all the incorporated areas of a municipality, and if the taxing unit is created before July 1 if millage is to be imposed in the ensuing county budget.
