- Payment deadline
- 2025 real-estate tax and 2026 manufactured-home tax: the official Treasurer notice lists the second-half due date as August 7, 2026; the reviewed current notice did not display the first-half real-estate date.
- Assessment appeal
- January 1–March 31, 2026 for the 2025 tax year, or the later statutory first-half collection closing date if applicable; file a DTE 1 complaint against valuation or assessment with the county Board of Revision through the Auditor under Ohio Revised Code §5715.19.

Valuation limits
No general county parcel-value cap was published. Ohio assesses real property at 35% of market value, reappraises every six years with triennial updates, and applies HB 920 reduction factors and the 10-mill limitation; House Bill 186 (effective March 20, 2026) creates an inflation-cap credit for qualifying property and taxing districts, shown on eligible 2026 bills.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
