Tennessee Code Title 62. Professions, Businesses and Trades § 62-5-316

(a) Any license that is not renewed by its expiration date becomes invalid. The holder of the invalid license shall not practice the profession for which the license was issued, nor shall an establishment be operated if the establishment's license has become invalid, until such time as the license has been renewed or reinstated or a new license has been issued.

(b) When any license issued by the board becomes invalid because of nonrenewal, the executive director shall send a written notice to the license holder at the license holder's last known address, informing the license holder that the license holder cannot practice that profession or operate that establishment until the invalid license is renewed or reinstated or a new license is issued. The notice shall also state that the license may be renewed or reinstated at any time within ninety (90) days of the license expiration date by payment of the renewal fee and of a penalty fee in an amount to be established by the board. Any license not renewed or reinstated within ninety (90) days of the license expiration date shall not be subject to renewal or reinstatement and the license holder shall reapply as for an initial license; provided, that any examination shall be limited to this chapter and any rules promulgated pursuant to this chapter, and that the education requirements in § 62-5-305(b)(6) and § 62-5-307(b)(6) are not applicable.
