Tennessee Code Title 67. Taxes and Licenses § 67-3-614

(a) Sixty (60) days after making a written request for release to the commissioner, the surety of a bond furnished by a licensee is released from any liability to the state accruing on the bond after the sixty-day period. The release does not affect any liability accruing before the expiration of the sixty-day period.

(b) The commissioner shall promptly notify the licensee furnishing the bond that a release has been requested. Unless the licensee obtains a new bond that meets the requirements of this chapter and files with the commissioner the new bond within the sixty-day period, the commissioner shall cancel the license.

(c) Either the principal or surety may request the commissioner to cause an audit to be made of the books and records of the principal, and the audit shall be commenced within ninety (90) days from the date of the request. Upon completion of the audit, and if no additional taxes, fees, interest or penalty is shown to be due, or the additional sum is paid to the commissioner, then and thereafter, all liability of the surety on the bond shall cease and the surety shall be released. Any collateral deposited as security with the commissioner shall be released and returned to the person entitled to it. Any real estate that has been pledged as security for the bond shall be released by the commissioner by the execution of a release for that purpose, which may be recorded in the same manner as other releases are recorded. The commissioner may require the principal on the bond to furnish the form for a release.
