Appraisal and Assessment: Board of Revision (BOR)

Board of Revision Overview
Every year between January 1 and March 31, taxpayers may file an appeal of their property assessment through the county’s Board of Revision. Board members include the Butler County Auditor, Butler County Treasurer, and the President of the Butler County Commission.

Once the Board of Revision issues a decision, the value that the board determines will remain the value for the year in which the complaint was filed and, if the complaint was filed in the first year of the Auditor’s three-year appraisal cycle, the following two years, or, if the complaint was filed in the second year of the three year cycle, the following year, unless there is a significant change in circumstances.  These include:  (i) adding a significant new tenant or the loss of a significant tenant, (ii) new construction at the property, (iii) destruction of the property in whole or in part; and (iv) an arms-length sale of the property.

For more information see our BOR brochure here or continue reading below.

In 2022, properly executed forms must be filed with the Butler County Auditor's Office by 4:30 p.m. on March 31, or postmarked by March 31. Forms received after the deadline will be dismissed.
