Ohio Property Tax Appeal — Key Facts
How to Appeal in Ohio
Check your assessment notice
Your county assessor mails assessment notices — usually in spring. The notice shows your assessed value and the appeal deadline. In most states you have 30–90 days from the notice date.
Gather comparable sales
Find 3–5 similar properties in your neighborhood that sold recently at prices below your assessed value. Use Zillow, Redfin, or your county recorder's public records. The more recent and similar the sales, the stronger your case.
File your formal appeal
In Ohio, you file with the County Board of Revision. File Complaint Against Valuation (Form DTE 1) with the County Board of Revision by March 31. The Board of Revision hears evidence and issues a decision. File before March 31 (annually).
Present your evidence at the hearing
Show up with your comparables. Be calm and factual. You don't need a lawyer. Appeals boards are accustomed to homeowners representing themselves. Simply demonstrating that comparable properties sold for less than your assessment is often enough to win a reduction.
Expert tip for Ohio
Ohio's March 31 deadline is fixed and unforgiving. Submit DTE Form 1 to your County Auditor (not the Assessor). Recent sale price is the strongest evidence.
