How to Appeal Property Taxes in Ohio: Board of Revision Process
TL;DR
Ohio property tax complaints go to your county Board of Revision. The filing deadline is March 31, 2026. Ohio reassesses property every six years with triennial updates, and effective tax rates vary widely by county, from around 0.8% to over 2.2%. You can file on your own with no fee, and success rates are solid if you bring comparable sales data.
Ohio property taxes fund local schools, county government, and municipal services. Because the state relies heavily on property taxes, effective rates tend to run higher than the national average. The statewide average effective rate is about 1.53%, but some counties in the Cleveland, Columbus, and Cincinnati metro areas push well past 2%.
The upside is that Ohio gives every homeowner the right to challenge their assessed value through a straightforward Board of Revision complaint. You don't need a lawyer. You don't need to pay a filing fee. You just need evidence that your value is wrong.
How Ohio Property Tax Assessments Work
Each county auditor sets property values based on a six-year reappraisal cycle. Between full reappraisals, there's a triennial update at the three-year mark. The county auditor adjusts values based on local sales trends during these updates.
Ohio uses a "35% assessment rate." Your taxable value is 35% of the auditor's appraised market value. So if your property is appraised at $300,000, your taxable (assessed) value is $105,000. The millage rate is then applied to that $105,000 figure.
| Component | Example |
|---|---|
| Auditor's Appraised Value | $300,000 |
| Assessment Rate | 35% |
| Assessed (Taxable) Value | $105,000 |
| Total Mill Rate (example) | 85 mills |
| Annual Tax Bill | $8,925 |

Filing Deadline and Requirements
March 31, 2026
The standard deadline to file a Board of Revision complaint is March 31 of the tax year. For tax year 2025 values (payable in 2026), you would file by March 31, 2026. The complaint applies to the current tax year's values.
Who Can File
Any property owner, tenant (if they pay the taxes), or tax-exempt entity can file a Board of Revision complaint. Filing is free in most counties.
What You Need
- A completed Board of Revision Complaint form (DTE Form 1)
- Your property's parcel number
- The auditor's current appraised value
- Your opinion of the correct value
- Supporting evidence (comparable sales, appraisal, property condition documentation)
Step-by-Step: Ohio Property Tax Appeal
Step 1: Review Your Assessment
Look up your property on your county auditor's website. Check the appraised value, the property details (square footage, bedrooms, bathrooms, lot size), and the property classification. Errors in the physical description are surprisingly common and can inflate your value.
Step 2: Gather Comparable Sales
Find 3-5 recent sales of similar properties in your area that sold for less than your appraised value. Focus on homes within a half-mile radius that sold in the last 12 months. Match as closely as possible on size, age, condition, and features. For help finding and presenting comps, see our guide to comparable sales.
Step 3: Document Property Issues
Photograph any condition problems: foundation cracks, water damage, outdated systems, needed repairs. If your home backs up to a busy road, railroad tracks, or commercial property, document that too. These negative factors reduce value.
Step 4: File DTE Form 1
Submit the Board of Revision Complaint (DTE Form 1) to your county Board of Revision by March 31. You can usually file in person at the county courthouse or by mail. Some counties accept electronic filings.
Step 5: Attend the Hearing
The Board of Revision will schedule a hearing, typically within 2-4 months of filing. The board usually consists of the county auditor (or representative), a county commissioner, and a probate court judge. Present your evidence clearly and concisely. Keep your presentation under 15 minutes.
Step 6: If You Disagree with the Decision
You can appeal a Board of Revision decision to the Ohio Board of Tax Appeals (BTA) within 30 days. From there, you can appeal to the Ohio Supreme Court. These further appeals are more formal and may require legal help.
Ohio Property Tax Exemptions
Homestead Exemption
Ohio's homestead exemption reduces the taxable value of your home by $26,200 (for tax year 2024, adjusted periodically). It's available to homeowners who are 65 or older, or permanently and totally disabled. There is no income limit for the basic exemption. Apply through your county auditor by the first Monday in June.
Owner-Occupancy Credit
Ohio provides a 2.5% rollback (reduction) on property taxes for owner-occupied homes. This is applied automatically when you file as an owner-occupant, but make sure your county has you listed correctly.
Disabled Veterans Exemption
Veterans with a 100% service-connected disability can receive a full property tax exemption on their homestead. Veterans with lower disability ratings may qualify for a partial exemption.
Tips for Winning Your Ohio Appeal
- Check the property record card: Auditors sometimes have incorrect square footage, extra rooms, or wrong lot sizes on file. If the physical data is wrong, point it out.
- Use the auditor's own data: County auditors publish recent sales data. Use their records to find comparable sales that support a lower value.
- Focus on the valuation date: Ohio values property as of January 1 of the tax year. Use sales data close to that date.
- Be specific with your requested value: Don't just say your value is too high. State the exact value you believe is correct and show how you arrived at it.
- Dress professionally and be respectful: Board of Revision hearings are quasi-judicial proceedings. Treat them seriously.

- Hamilton County: Board of Revision, Hamilton County Auditor's Office

Frequently Asked Questions
Can my value go up if I file an appeal?
Yes. In Ohio, the Board of Revision can increase your value, decrease it, or leave it the same. However, this rarely happens in practice. If you have legitimate evidence of overvaluation, the risk is low.
How long does the process take?
Most Board of Revision complaints are resolved within 3-6 months of filing. If you appeal further to the Board of Tax Appeals, expect an additional 12-24 months.
Do I need an appraisal?
A professional appraisal is not required but significantly strengthens your case, especially for higher-value properties. For homes under $300,000, good comparable sales data is often sufficient. For more on building evidence, see our appeal evidence guide.
What if I just bought the house?
If you recently purchased your home for less than the auditor's appraised value, your purchase price is strong evidence. Bring your closing statement to the hearing. For more, see our guide on appealing after buying a home.
How often should I appeal?
Review your assessment each year, but you especially want to appeal after reappraisal years (every six years) and triennial update years when values change significantly.
