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.

2020 and 2021 Value Appeals

In a 2022 Ohio Board of Tax Appeals decision the Butler County Auditor’s Office was mandated to retroactively increase residential property values within four taxing districts (Fairfield, Fairfield Township, Hamilton and West Chester) for the effective value dates of January 1, 2020 and 2021.

The Butler County Board of Revision adopted a motion on December 7, 2022 allowing affected parties (residential property only) to challenge their property values for the effective true value dates of January 1, 2020 and 2021.

The Board of Revision complaint process for these retroactive effective value dates will run concurrent with the current effective value date of January 1, 2022, and will follow the same policy and procedures as set forth by the Board of Revision at its January 9, 2023 organizational meeting.

The retroactive value appeals are subject only to the state mandated value increases above the effective values established on January 1, 2020 and 2021.
