Me. Stat. tit. 32 § 18144
A license expires on the date set by the Commissioner of Professional and Financial Regulation pursuant to Title 10, section 8003, subsection 4 for the licensing period for which the license was issued. A renewal license may be issued for each ensuing licensing period in the absence of any reason or condition that might warrant the refusal to grant a license upon receipt by the board of the written request of the applicant and the fee for the license set under section 18143. An expired license may be reissued up to 90 days after the date of expiration upon payment of a late fee in addition to the renewal fee as set under section 18143. An individual who submits an application for renewal more than 90 days after the license expiration date is subject to all requirements governing new applicants under this chapter and is subject to a renewal fee, late fee and additional late fee as set under section 18143, except that the board may, in its discretion and giving due consideration to the protection of the public, waive examination if that renewal application is made within 2 years from the date of that expiration.
