Before the 1st day of each December, a licensee must pay to the Director, and the Department must receive, the annual license fee required by Section 2 for the next succeeding calendar year. The license shall expire on the first of January unless the license fee has been paid prior thereto.
In addition to such license fee, the reasonable expense of any examination, investigation or custody by the Director under any provisions of this Act shall be borne by the licensee.
If a licensee fails to renew his or her license by the 31st day of December, it shall automatically expire and the licensee is not entitled to a hearing; however, the Director, in his or her discretion, may reinstate an expired license upon payment of the annual renewal fee and proof of good cause for failure to renew.
