Each registrant shall keep accurate records of his sales, and shall file a semiannual report covering the periods January 1 through June 30, and July 1 through December 31. Such reports shall be due within 30 days from the close of each period. If the report is not filed within the 30-day period or is false in any respect, the Commissioner may revoke the registration. For the purpose of auditing reports, each registrant shall make his records available for audit from time to time as the Commissioner may deem necessary. (1977, c. 233, s. 7.)
