The office also handles the collection and distribution of all non-tax revenue in the County.

Disbursements of cash to cover County obligations is also the responsibility of this office. These disbursements may be to cover bills paid by County warrants or to cover bond payments or remittances to other government agencies for which the County collects taxes.

It is in the public's best interest to have any cash invested. That investment responsibility rests in the Treasurer's Office. The present investment program is constantly being reviewed and improved.

Record-keeping and reporting are also important functions of the office. Tax and license payment records are maintained as well as disbursement records. Additionally, the office is required to keep detailed records of school budgets. Reports from this office go to the State, the City of Hardin, schools, irrigation, and various districts, and to the County Commissioners.
