The general duties of the treasurer are to receive and record all revenues due the municipality and to make necessary disbursements only upon authorization of the municipal officers. 

Although the treasurer is certainly an important and primary advisor to the municipal officers with regard to financial matters, the treasurer is prohibited from acting in an unauthorized or unilateral way, such as by choosing banking or lending institutions, making unauthorized disbursements of any kind, setting financial policy, or initiating loans. 

The treasurer may disburse money only on a warrant for that purpose approved by the municipal officers by majority vote at a public meeting and signed by a majority of them. 

The treasurer is responsible for keeping the municipality's financial accounts in accordance with generally accepted principles of municipal accounting. The treasurer is instrumental in presenting clear financial information to the municipality's voters, primarily through the town report, and to the municipal officers so that the board can make informed decisions, particularly with regard to municipal borrowing and investment.  The treasurer is also responsible for accepting tax warrants from the state and county government and making sure they are promptly paid.
