Tennessee Code Title 67. Taxes and Licenses § 67-4-503

(a) Notwithstanding any law to the contrary, except where specifically authorized by general law, when any county has pursuant to private act levied a tax on a privilege, no municipality within that county shall later levy a tax on the same privilege, and when any municipality has previously levied a tax on a privilege pursuant to general law or private act, the county in which such municipality is located shall not levy a tax on the same privilege. Any municipality with a population of five thousand (5,000) or more, according to the 1980 federal census or any subsequent federal census, located partly in one (1) county having a metropolitan form of government and partly in another county, may levy a hotel/motel tax, even if either of the counties in which the municipality with a population of five thousand (5,000) or more, according to the 1980 federal census or any subsequent federal census, is located levies such tax.

(b) This section does not apply to any city that has constructed a qualifying project or projects under the Convention Center and Tourism Development Financing Act of 1998, compiled in title 7, chapter 88, as it relates to the authority of such city to levy an occupancy tax.
