Mercer County Overview
Mercer County Tax Assessment Process
The Mercer County Auditor is the chief assessor under ORC Chapter 319. The auditor views and values every parcel. Mercer County is dominated by farm ground. Row crops and dairy operations take up most of the land. Residential properties sit in Celina, Coldwater, and a handful of smaller villages. The auditor assigns market value and applies Ohio's 35% assessment rate. Lakefront properties near Grand Lake St. Marys tend to carry higher values than inland farm tracts.
Full reappraisals come every six years. The triennial update keeps values current between cycles. Mercer County's stable agricultural base means most values do not swing as wildly as in fast-growing suburbs. But lakefront parcels and new construction can see bigger changes during a reappraisal. House Bill 920 reduction factors offset increases on existing levies. The auditor calculates and applies these factors each year.
