Welcome to the Montgomery County 2017 Triennial Update web site. As County Auditor, I am required by the State of Ohio to reappraise all property in the county once every six years and update values in the third year of the cycle. The last triennial update was for tax year 2011 and the next is for tax year 2017 (payable 2018). This web site is intended to provide an overview of the 2017 Triennial Update.
