December 31, 2026 for a 2026 real-property homestead application; file with the county Auditor under Ohio's DTE 105A schedule.
Senior relief
Ohio Homestead Exemption: qualifying homeowners age 65+, permanently and totally disabled homeowners, eligible surviving spouses, and qualifying 100% disabled veterans may receive a reduction of up to $29,000 of market value for the 2026 application period. New senior/disabled applicants generally must have 2025 Ohio MAGI of $41,000 or less; the owner must own and occupy the home as the principal residence on January 1. Enhanced disabled-veteran and public-service-officer surviving-spouse programs have separate rules.
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 automatic Inflation Cap Credit for qualifying school-district/JVS levy growth; it is a tax credit/collection limitation, not a general cap on appraised or taxable parcel value.
