Ohio's Board of Revision (BOR) is the formal body that hears property tax valuation complaints in each county. For commercial property owners in Cuyahoga County, Franklin County, Hamilton County, and across the state, the BOR process is the primary path to a reduced assessment. This guide covers everything you need to know — from filing your complaint to presenting your case at the hearing.
What Is the Ohio Board of Revision?
Each county in Ohio has a Board of Revision composed of the county auditor, the county treasurer, and the president of the county commissioners. The BOR has statutory authority to hear complaints about property values and make adjustments. It serves as the first formal step in Ohio's property tax appeal process.
Unlike Michigan, where you must first go through a local Board of Review before reaching the Tax Tribunal, Ohio's BOR is effectively the initial and primary venue. From the BOR, you can appeal to the Board of Tax Appeals (BTA) and ultimately to the Ohio Supreme Court. For a comparison of the appeal process across states, see our property tax appeal process resource. For the Ohio-specific overview, see our Ohio Board of Revision page.
When to File: Deadlines and Timing
In Ohio, property tax complaints must be filed with the Board of Revision by March 31st of the year following the tax year in question. For example, to challenge your 2025 assessment, you must file by March 31, 2026.
Ohio operates on a triennial reappraisal cycle. The county auditor reappraises all property every six years, with an update (equalization) at the three-year midpoint. In reappraisal and update years, values can change significantly — making those years especially important for filing complaints.
Timing matters beyond just meeting the deadline. Filing early gives you more time to negotiate with the county and prepare for a hearing. Filing late — even if technically on time — can compress the process and limit your options. Our property tax deadlines resource has the complete calendar for Ohio, Michigan, and Indiana.
How to File a Complaint
Filing a complaint with the Board of Revision requires submitting a Complaint Against the Valuation of Real Property (DTE Form 1). This form asks for your property information, the current value on the tax roll, and the value you believe is correct. You must also state the basis for your complaint — typically that the property is over-valued.
The filing fee varies by county but is generally modest. Some counties also accept electronic filings. Once your complaint is filed, the county auditor will schedule a hearing — typically several months after the filing deadline. You will receive notice of the hearing date in advance.
Preparing Your Evidence
Ohio's Board of Revision considers all three approaches to value: the income approach, the sales comparison approach, and the cost approach. The weight given to each approach depends on the property type and the evidence presented. For commercial income-producing properties, the income approach often carries the most weight.
The most effective evidence packages include:
- Recent comparable sales — arm's-length transactions of similar commercial properties in the same market area
- Income and expense statements — actual financial data for your property, showing NOI and operating costs
- Capitalization rate analysis — evidence of appropriate cap rates derived from market transactions, not generic surveys
- Appraisal reports — a certified appraisal from a licensed commercial appraiser is the strongest single piece of evidence
- Property condition documentation — photographs and reports showing deferred maintenance, functional obsolescence, or environmental issues

What Happens at the Hearing
BOR hearings are semi-formal proceedings. You (or your representative) will present your case to the three-member board. The county auditor's office will typically present the assessor's position. Both sides can submit documents, testimony, and other evidence.
Hearings are usually brief — often 15 to 30 minutes for straightforward cases. However, complex commercial properties with significant valuation disputes may require longer presentations. The board will issue a written decision, usually within a few weeks of the hearing.
Having professional representation at the hearing can make a significant difference. An experienced property tax consultant knows how to frame the evidence, anticipate the county's arguments, and present a compelling case within the limited hearing window.
Counter-Complaints: What Property Owners Should Know
Ohio allows both property owners and taxing authorities to file complaints. This means that if you file a complaint seeking a reduction, the school board or other taxing authority can file a counter-complaint arguing that your property is under-assessed. While counter-complaints are more common for properties that recently sold at a high price, they can apply to any complaint.
This two-way risk makes it important to file your complaint with a solid evidence base. If you are asking for a reduction that you can support with market data, appraisals, and income analysis, counter-complaints are unlikely to succeed. The key is preparation.
After the BOR Decision: Next Steps
If the Board of Revision does not grant an adequate reduction, you can appeal to the Ohio Board of Tax Appeals (BTA). The BTA conducts a de novo review — meaning it considers the case fresh, without deference to the BOR's decision. From the BTA, you can further appeal to the Ohio Supreme Court, though few cases reach that level.
It is worth noting that many BOR cases settle through negotiation with the county before or after the hearing. Negotiated settlements can produce faster results and save both parties the time and expense of extended litigation. Learn about our approach and typical property tax appeal success rates.
Industries with Strong Appeal Opportunities in Ohio
Certain commercial property types consistently present strong appeal opportunities in Ohio. Retail properties affected by shifting consumer behavior, industrial properties with significant depreciation or functional obsolescence, multifamily complexes with rising vacancy, and banking facilities affected by branch consolidation all tend to be over-assessed relative to their current market values.
The dark store theory has also been a factor in Ohio retail property appeals, though its application varies by county and property type.
