Welcome to the Montgomery County Board of Revision website. The Board of Revision (BOR) is a three person quasi-judicial board comprised of a member from the offices of the County Auditor, the County Treasurer, and the Board of County Commissioners

The BOR is responsible for conducting hearings to determine the Fair Market Value of property. It allows tax payers an opportunity to share with the county information about their property.

*Note: the BOR can only make changes to property values. It is not able to change tax rates or tax amounts due.

The Board of Revision is located on the third floor of the County Administration building, located at 451 W Third St in Dayton. The BOR is open Monday-Friday 8am-5pm.

The BOR filing period will reopen on January 1 and last until March 31.

Property owners received notice of their new tentative 2020 property values in the mail at the beginning of August, as part of the 2020 Property Reappraisal. Property owners who wish to appeal this new 2020 value do not need to take part in this year’s Board of Revision process. Instead, they should call the Property Owners Hotline at 937-225-5096 to schedule an informal review meeting.
