Letter from the Treasurer

The Treasurer's Office is the property tax collector for Benton County and the Cities, School Districts, Fire Departments, and all the other taxing authorities in the County. Property Taxes are levied on the property by the various taxing authorities  based on the valuation and current property usage as set by the Assessor's Office.

As the "banker" for Benton County, the County Treasurer's Office is also responsible for collecting all other money other  County departments collect such as fees for services, licenses, and revenues from bond issues and special assessments.

As your Treasurer, I value your opinion and will consider it in establishing policies, designing services and updating our  service to you. If we have let you down, please tell me. If you are pleased, I would like to hear that too.

Kenneth Spencer, Jr.
Benton County Treasurer
