Ohio Notes
Important state-specific details
Ohio property assessed at 35% of appraised (market) value - this 35% is the "assessed value" on your tax bill.
Taxes billed in ARREARS: the 2026 bill covers Tax Year 2025.
REAPPRAISAL CYCLE: County auditors conduct full sexennial (6-year) reappraisal; triennial (3-year) statistical update at midpoint; values can change significantly in reappraisal years.
SCHOOL COUNTER-COMPLAINTS: Ohio allows school districts to file counter-complaints when homeowners appeal their assessment - this means Ohio property tax appeals carry a risk that the school district could argue for a HIGHER value; consult an attorney for larger appeals.
KEY EXEMPTIONS (apply with County Auditor):
Homestead Exemption: income-based (or age 65+/disabled); reduces taxable value; apply with county auditor; deadline typically December 31 for the following tax year
Owner-occupancy Reduction (2.5% rollback): automatic reduction for owner-occupied homes
Non-business Credit (10% rollback): applies to most residential property
