Mercer County Auditor Office

The Mercer County Auditor serves as the chief fiscal officer and chief property assessor. The office sets fair market values on all land and buildings in Mercer County, then calculates assessed values at 35% of market value under ORC Section 319.54. Tax bills are computed using local levy rates applied against those assessed figures. The Auditor's online property search system provides free access to parcel data including owner name, address, legal description, assessed and market values, building characteristics, tax history, and sales records.

The Auditor's Office is at 101 North Main Street, Celina, OH 45822. Hours are Monday through Friday, 8:00 AM to 4:30 PM. Call (419) 586-6402 with questions. The office also runs a GIS mapping system where you can view parcel boundaries over aerial photos and click any lot to see its record.

Mercer County is one of Ohio's top agricultural counties. A large share of land is in farm use, which means the CAUV program plays a big role in how property gets valued here. The Auditor processes CAUV applications alongside standard residential and commercial assessments under ORC Chapter 319.
