Tony Brown, Guernsey County Auditor

Auditor Responsibilities 

As your County Auditor, I am responsible for a wide variety of duties that affect every resident of the County.  Ohio law places more fiscal responsibility upon the County Auditor than upon any other County Official. As the chief disbursing agent, fiscal officer, and tax assessor I faithfully exercise all power and perform all duties vested in or imposed by general law.

As Chief Fiscal Officer, I am responsible for issuing warrants for liabilities incurred by the County, it’s departments and agencies. The auditor’s office is responsible for the preparation of the County payroll, maintaining all financial records and reports, and establishing taxing rates for manufactured homes and real estate. Once collected, tax receipts are distributed to the appropriate city, village, township, fire district, or school district in accordance with the legally adopted rates. 

As Tax Assessor, I am responsible for determining the value of all real property in Guernsey County for tax purposes.  Every six years the Auditor must conduct a full reappraisal of real property, and every three years, an update of real property values is required.  Tax credits are also maintained in my office, including Owner Occupied Credit, Non-Business Credit and the Homestead Exemption.  We also are responsible for the valuation of farm land and the administration of the Current Agricultural Use Value program (CAUV).  

It is the duty of the Auditor to perform professionally the statutory duties of County Auditor with integrity, independence, and a spirit of innovation. We strive to provide our services with outstanding customer service while providing the public with access to accurate and reliable public information.
