Auditor

The Auditor calculates tax rates for all taxing entities in the County (schools, cities, townships, area schools etc) by applying taxes levied by those entities to the valuation of each property as determined by the Assessor, and then prepares a tax list showing each taxpayer’s share of the total. These figures are then certified to the County Treasurer’s Office. Many of the records prepared in the Auditor’s office are maintained permanently and are available for public use.

Financial duties of the auditor include the preparation of the County’s budget from material submitted by its departments and other agencies and issuing payment of all services, materials, and payroll charged to the County. The Auditor then maintains a ledger for each department in the County throughout the fiscal year (July 1 through June 30). The Auditor also keeps and maintains permanent financial records for the County. Many financial reports are published for public information.
