Local Tourism Development Zone Business Tax
Municipalities and counties may levy a privilege tax of up to 5 percent of the sale price on goods sold in a qualified public use facility or in a tourism development zone established under the Convention Center and Tourism Development Financing Act of 1998 codified in T.C.A. §§ 7-88-101, et seq. Businesses exempt from the business tax also are exempt under this tax. Passage of the tax requires a two-thirds vote of the governing body at two consecutive meetings. A petition signed by 10 percent of those who voted in the municipality in the latest gubernatorial election can require that the tax be put to referendum. Revenues from the tax will be used to pay the cost of the convention center or other qualified public use facility. Authority to levy this tax does not apply in Davidson County. T.C.A. §§ 67-4-3001, et seq.
