The license collector of the city of St. Louis shall make settlement annually on the first Monday in June and at the expiration of his term of office, with the treasurer of the city, for all fees so collected, deducted and retained by him, as provided in section 82.395; and all fees so collected, deducted, and retained shall be computed for the year or part of the year next preceding the dates of such settlement. The license collector shall present for allowance proper vouchers for all disbursements made by him on account of all salaries, clerical hire and other expenses of his office, and other costs of collecting all revenues, taxes, licenses and other dues which he is or may be authorized to collect for the state, city and school, which shall be allowed and credited to him as against the fees so collected, deducted and retained by him. If the residue of such fees in the hands of the license collector after the annual settlement exceed two times the amount of the previous year’s disbursement for all salaries, clerical hire and other expenses of his office, such excess shall be paid into the treasuries of the state, city and school in proportion that the amount of revenue so collected for each bears to the total amount so collected for all, as such amounts shall be reflected in and by the settlement made annually on the first Monday in June.
