City treasurers are primarily responsible for managing the revenue and cash flow of the agency, banking, collection, receipt, reporting, custody, investment or disbursement of municipal funds.
They could also have oversight of other areas, such as the purchase of insurance, and collections of user fees such as utility usage and business licenses.
Elected municipal treasurers may only be required to be of legal age, over 18, for example, meet minimum residency requirements, perhaps six months or one year, and be a registered voter.
Some US states offer but may not require, extensive training and certification programs, such as the Certified California Municipal Treasurer.
Appointed municipal treasurers, not subject to residency requirements, are likely to be subject to competition and likely must have finance-related college degrees, prior investment experience, municipal department head experience and appropriate training and certifications.
