It shall be the duty of the county director of revenue to collect and receive all license fees imposed by the ordinance or resolution and to keep records showing the amounts received by him or her from each employer and employee. The director or any agent or employee designated by him or her shall be authorized to examine the books, papers, and records of any employer or of any licensee in order to determine the accuracy of any return made, or if no return was made to ascertain the amount of license fees due under the terms of the ordinance or resolution by such examination. The director is hereby authorized to examine any person under oath concerning any gross receipts which were or should have been shown in the return and to this end he or she may compel the production of books, papers, records, and the attendance of persons before him or her, whether as parties or as witnesses, whom he or she believes to have knowledge of such gross receipts or compensation, to the extent that any officer empowered to administer oaths in this state is permitted to make investigations.
