All persons authorized to sell park permits, except employees of the department who receive a regular salary from the state, may charge the purchaser as compensation 15 cents additional for each annual park permit and 10 cents additional for each daily park permit issued. On or before February 15 of each year a complete report of all permits sold during the previous calendar year shall be filed with the department by each person authorized to sell park permits, and all unsold park permits for the previous year shall be returned to the department.
