Except as otherwise provided by law, all moneys collected or received by an officer, employee or agent of a local school administrative unit or an individual school shall be deposited in accordance with this section. Each officer, employee and agent of a local school administrative unit or individual school whose duty it is to collect or receive any taxes or other moneys shall deposit his collections and receipts daily. If the board of education gives its approval, deposits shall be required only when the moneys on hand amount to as much as two hundred fifty dollars ($250.00), but in any event a deposit shall be made on the last business day of the month. All deposits shall be made with the finance officer or in an official depository. Deposits in an official depository shall be immediately reported to the finance officer or individual school treasurer by means of a duplicate deposit ticket. The finance officer may at any time audit the accounts of any officer, employee or agent collecting or receiving any taxes or other moneys, and may prescribe the form and detail of these accounts. The accounts of such an officer, employee or agent shall be audited at least annually. (1975, c. 437, s. 1; 1981, c. 423, s. 1.)
