If the annual statement of collection is not filed as required under AS 08.24.210, the failure to file constitutes grounds for the immediate suspension of the collection agency license of the licensee failing to file the statement, and the department shall notify the licensee by registered or certified mail that the license of the licensee will be suspended upon the expiration of 15 days after the date on which the notice was mailed unless the licensee complies with the provisions of AS 08.24.210. However, for good cause shown and upon satisfactory proof furnished by the licensee that the failure to file the statement was due to a condition not within the control, or was due to excusable neglect, of the licensee, the department may permit the filing of the statement after the time limited and excuse the failure to file the statement within the time limited. If the statement required by AS 08.24.210 is not filed as required by this section, the department shall revoke the license.
