The City Treasurer is responsible for receipt, deposit, and recording of all revenues for the City of Quincy.  The Treasurer is also responsible for the control and monitoring of all the City’s bank accounts and for investing idle funds.  The Treasurer is required to keep records showing all money received, the source from which it was received, the purpose for which it was paid out, and to keep accurate accounting of all debts due to the city.

Money collected by the treasurer’s office is deposited daily in an interest-bearing account. Idle funds are reviewed daily and invested according to anticipated needs.

Money is invested primarily in banks that have branches located within the Quincy city limits. State statute limits the amount deposited at a bank with a formula based on the bank's equity capital.

Monthly reports are required by the City Council showing the financial status of the city, including the amounts received and spent during the month for which the report is filed.

An annual report is also filed showing the total amount of all receipts and expenditures of the city, and all transactions as Treasurer during the preceding fiscal year.
