The city treasurer shall be the custodian of all money belonging to the city. The city council shall pay the actual premium of the bond or insurance coverage of such treasurer.
(2) The city treasurer shall keep a separate account of each fund or appropriation and the debts and credits belonging thereto. He or she shall give every person paying money into the treasury a receipt therefor, specifying date of payment and on what account paid. He or she shall also file copies of such receipts, except tax receipts, with his or her monthly reports, and he or she shall at the end of every month, and as often as may be requested, render an account to the city council, under oath, showing the state of the treasury at the date of such account, the amount of money remaining in each fund and the amount paid therefrom, and the balance of money in the treasury. The city treasurer shall also accompany such account with a statement of all receipts and disbursements, together with all warrants redeemed and paid by him or her, which warrants, with all vouchers held by him or her, shall be filed with his or her account in the city clerk's office. He or she shall produce and show all funds shown by such report to be on hand, or satisfy the city council or its committee that he or she has such funds in his or her custody or under his or her control.
