How to File a Property Value Complaint in Hamilton County, Ohio (2026 Guide)

Property owners in Hamilton County, Ohio can challenge an inaccurate property valuation by filing Form DTE 1 with the Hamilton County Auditor and Board of Revision between January 2 and March 31. Submit clear evidence such as recent sales data, appraisals, or property damage photos to support your claimed fair market value. After filing, attend the scheduled hearing, and optionally tender taxes at the contested value while your complaint is under review.

What is a Property Value Complaint

A property value complaint, also known as a valuation appeal, is a formal request to the Hamilton County Board of Revision (BOR) to review your property’s assessed value. The county auditor determines property values each year for tax purposes, but sometimes these assessments may not reflect the true market value.

Why Do People Search for Property Value Complaints

Many homeowners search for property value complaints when:

• Property taxes rise unexpectedly after a reassessment
• They notice similar homes in their neighborhood are assessed lower
• They recently purchased the property and feel the assessed value is too high

Filing a complaint ensures you are taxed fairly based on accurate property valuation.

How Property Value Complaints Affect Your Taxes

Property taxes in Hamilton County are calculated using the assessed value set by the auditor. A lower assessed value directly reduces your annual property taxes, potentially saving thousands of dollars for homeowners.

Step-by-Step Guide to Filing a Property Value Complaint

Step 1 – Identify Your Property Assessment

Before filing, you need to know your current assessed value:
