2025 REVALUATION - IN PROGRESS

The Miami County Auditor is finalizing the process of a state mandated reappraisal of all properties. New values will go into effect January 1, 2025, and will be payable on the 2026 tax bills.  Beginning Wednesday, August 16th, 2024, and running through mid-February 2025, there will be teams of appraisers that will be verifying property values and characteristics as part of the state mandated appraisal process.  The role of these appraisers will be to inspect all properties from the exterior. These individuals will be working on behalf of the Miami County Auditor’s office, but are employed by Vision Government Solutions. They will be identified with badges and car signs. Questions should be directed to the Miami County Auditor’s office at 937-440-5925 between 8:00 am and 4:00 pm M-F.
