Notwithstanding the fact that a certificate shall not contain an execution in behalf of one or more qualified municipalities within the special district, if the combined total of the populations of all such absent municipalities is less than one-half of the aggregate population of all qualified municipalities located within the special district, the submitting political subdivisions shall, in behalf of the absent municipalities, specify a percentage of that portion of the remaining proceeds which each such municipality shall receive, which percentage shall not be less than that proportion which each absent municipality's population bears to the total population of all qualified municipalities within the special district multiplied by that portion of the remaining proceeds which are received by all qualified municipalities within the special district. For the purpose of determining the population of the absent municipalities, only that portion of the population of each such municipality which is located within the special district shall be computed. No certificate may contain a total of specified percentages in excess of 100 percent. The certificate shall be filed with the commissioner by March 1, 1980, for those special districts in which the tax authorized by this article is being levied on January 1, 1980. For all other special districts in which the tax shall be imposed subsequent to January 1, 1980, the certificate shall be filed with the commissioner within 60 days after the tax is imposed within the district. The commissioner shall continue to distribute the proceeds of the tax as otherwise provided in this Code section until the first day of the next calendar year following the month in which the commissioner receives a certificate as provided in this Code section, which certificate shall provide other percentages upon which the commissioner shall make the distribution to the political subdivisions entitled to the proceeds of the tax. At such time, the commissioner shall thereafter distribute the proceeds of the tax in accordance with the directions of the certificate.
