Tennessee Code Title 47. Commercial Instruments and Transactions § 47-26-1010

(a) The commissioner shall establish a system of license renewals at alternative intervals throughout the calendar year. Licenses issued under the alternative method are valid for twenty-four (24) months and shall expire on the last day of the last month of the license period. During a transition period, or at any time thereafter, when the commissioner determines that the volume of work for any given interval is unduly burdensome or costly, either the licenses or renewals, or both of them, may be issued for terms of not less than six (6) months nor more than eighteen (18) months. The application fee imposed for any license under the alternative interval method for a period of other than twenty-four (24) months shall be proportionate to the annual fee, except that the proportional fee shall be rounded out to the nearest quarter of a dollar ($0.25). Application fees shall be nonrefundable. While the commissioner will attempt to forward public weighmaster license renewal forms to all currently licensed individuals, it is the licensed individual's ultimate responsibility to ensure that their license remains current.

(b) A thirty-day grace period shall be given to renew licenses. After the grace period expires, a twenty-five dollar ($25.00) late fee (not prorated per day) shall be levied on each renewal application received.
