1. Any city may, by a majority vote of its council or governing body, impose a sales tax for the benefit of the public mass transportation system operating within such city as provided in sections 92.400 to 92.421.

2. The sales tax may be imposed at a rate not to exceed one-half of one percent on the receipts from the sale at retail of all tangible personal property or taxable services at retail within any city adopting such tax, if such property and services are subject to taxation by the state of Missouri pursuant to the provisions of sections 144.010 to 144.525. Seven and one-half percent of the sales tax shall be distributed to the interstate transportation authority pursuant to the provisions of section 92.421.

3. Within ten days after the adoption of any ordinance imposing such a sales tax, the city clerk shall forward to the director of revenue by United States registered mail or certified mail a certified copy of the ordinance of the council or governing body. The ordinance shall reflect the effective date thereof and shall be accompanied by a map of the city clearly showing the boundaries thereof.

4. If the boundaries of a city in which such sales tax has been imposed shall thereafter be changed or altered, the city clerk shall forward to the director of revenue by United States registered mail or certified mail a certified copy of the ordinance adding or detaching territory from the city. The ordinance shall reflect the effective date thereof, and shall be accompanied by a map of the city clearly showing the territory added thereto or detached therefrom. Upon receipt of the ordinance and map, the tax imposed by sections 92.400 to 92.421 shall be effective in the added territory or abolished in the detached territory on the effective date of the change of the city boundary.
