Tennessee Code Title 68. Health, Safety and Environmental Protection § 68-104-206

A license holder with an unexpired license may apply for a new license at any time before the license expires. An exhibitor whose license has been expired for ninety (90) or fewer days may renew the license and have it retroactive to the date the old license expired by applying and paying a fee equal to one and one-half (1 1/2 ) times the normal fee. This section does not prevent the fire marshal from denying a new license, if the applicant does not comply with this part or rules of the fire marshal.
