(a) As a condition precedent for authority to levy the tax or to collect any proceeds from the tax authorized by this article for the year following the initial year in which it is levied and for all subsequent years, the county whose geographical boundary is conterminous with that of the special district and each qualified municipality therein receiving any proceeds of the tax shall adjust annually the millage rate for ad valorem taxation of tangible property within such political subdivisions as provided in this subsection. The governing authority of each such political subdivision shall compute the millage rate necessary to produce revenue from taxation of tangible property in its respective political subdivision which, when combined with other revenues reasonably expected to be received by the political subdivision during the year other than revenues derived from the tax imposed pursuant to this article, would provide revenues sufficient to defray the expenses of the political subdivision for the year. The millage rate so ascertained shall then be reduced by a millage rate which, if levied against the tangible property within the political subdivision, would produce an amount equal to the distribution of the proceeds of the tax imposed by this article which were received by the political subdivision during the preceding year. The tax bill of each ad valorem taxpayer in the political subdivision shall show in a prominent manner the millage rate first ascertained as provided in this subsection and shall show such millage rate reduced by the millage rate required to raise an amount of revenue equal to the distribution of the proceeds of the tax imposed by this article during the previous year. The remainder shall be the millage rate upon which each taxpayer's bill shall be based. The tax authority of each such political subdivision shall cause to be shown in a prominent manner on the tax bill of each ad valorem taxpayer the dollar amount of reduction of ad valorem property taxes which the taxpayer has received as a result of the political subdivision's sharing in the proceeds of the tax authorized to be imposed by this article; provided, however, that the dollar amount of reduction of ad valorem property taxes shall not be calculated or shown on those forms used for the registration and taxation of motor vehicles or trailers.

(b) This Code section shall not be construed to require a county or municipality to prepare and mail ad valorem property tax bills when the ad valorem property tax millage rate in the county or municipality has been reduced to zero as a result of the receipt of proceeds from the tax levied pursuant to this article.
