Michigan Compiled Laws, Chapter 207. Taxation § 207.1061

Sec. 61. (1) If the surety of a bond provides the department with a written request for a release from the bond, the surety is released from any liability to the state accruing on the bond more than 60 days after the date of the request. The release does not affect any liability accruing before the expiration of the 60-day period. After receiving a written request for release, the department shall promptly notify the licensee furnishing the bond that a release has been requested. If the licensee does not obtain a new bond that meets the requirements of this act and does not file the new bond with the department within the 60-day period, the department may revoke the licensee's license.

(2) Sixty days after a licensee makes a written request to the department for release of a cash deposit, the cash deposit is canceled as security for any obligation accruing after the expiration of the 60-day period. However, the department may retain all or part of the cash deposit for up to 4 years and 1 day as security for any obligations accruing before the effective date of the cancellation. Any part of the deposit that is not retained by the department shall be released to the licensee. Before the expiration of the 60-day period, the licensee may be required to provide the department with a bond that satisfies the requirements of this act. The department may cancel the license if the licensee does not provide the bond required by this subsection.

(3) A licensee who filed a bond or other security under this act may request that the department return, refund, or release the bond or security if the department determines that the licensee has continuously complied with the provisions of this act for the previous 4 years. However, if the department determines that the revenues of the state would be jeopardized by a return, refund, or release of the bond or security, the department may retain the bond or security, or having released it, may reimpose a requirement for bond or security to protect the revenues of this state. If requested by a licensee, the department's determination may be reviewed in accordance with 1941 PA 122, MCL 205.1 to 205.31.
