How Clinton County Assesses Property

35%of market value

Assessed by: Clinton County Auditor's Office

Assessment cycle: triennial

Notices typically mailed: Spring (typically by mid-May)

Ohio law requires all property to be assessed at 35% of market value. This means your property tax is calculated on the assessed value, not the full market value. For example, if your home's market value is $211,900 (Clinton County's median), at Ohio's 35% assessment ratio your assessed value would be $74,165, resulting in approximately $2,520 in annual taxes at the county's effective rate of 1.19%.

The Appeal Process

Appeals are heard by the Board of Revision. The Board of Revision hearing is a recorded legal proceeding where you present evidence supporting your opinion of value. The school district may file a counter-complaint and present opposing evidence. The Board can increase, decrease, or maintain your property value based on the evidence presented.

Step 1: Request an informal review with the Clinton County Auditor's Office before filing a formal appeal. Schedule an appointment at 937-382-2250 to discuss your property valuation and present initial evidence.

Step 2: Gather supporting evidence including recent comparable sales (similar homes sold within the past year), photographs documenting property condition, repair estimates for any damage or defects, and a recent independent appraisal if available.

Step 3: Complete DTE Form 1 (Complaint Against the Valuation of Real Property) available from the Clinton County Auditor's website at clintoncountyauditor.org. Fill out the form completely with your opinion of market value and attach all supporting documentation.

Step 4: File your completed complaint form with the Clinton County Board of Revision through the Auditor's Office between January 1 and March 31 (for the prior tax year). Submit by mail to 1850 Davids Drive, Suite 303, Wilmington, OH 45177, in person during business hours, or by fax to 937-382-4090.

Step 5: Attend the Board of Revision hearing where you will present your evidence. The Board consists of the County Auditor, County Treasurer, and a County Commissioner. Hearings are recorded and all documents are public record. Be prepared for the possibility that the local school board may file a counter-complaint.

Step 6: Receive the Board of Revision's decision by mail or email. The Board has authority to increase, decrease, or maintain your property value. All decisions are held for 30 days pending appeal.

Step 7: If you disagree with the Board of Revision decision, file DTE Form 4 (Notice of Appeal) with either the Ohio Board of Tax Appeals or Clinton County Court of Common Pleas within 30 days of the decision letter date.

Step 8: If appealing to the Board of Tax Appeals, file electronically at bta.ohio.gov or contact them at 614-466-6700. You must file the notice with both the BTA and the Board of Revision within 30 days or the appeal will be dismissed.

For a successful Clinton County property tax appeal, you need recent comparable sales showing similar homes in your area that sold for less than your assessed value within the past year. Include photographs documenting any property defects, damage, or poor condition issues that reduce your home's value. Professional evidence such as an independent appraisal, repair estimates from contractors, or documentation of structural problems strengthens your case significantly. The burden of proof is on you as the complainant, so provide all relevant evidence with your initial DTE Form 1 filing, as information not presented to the Board cannot later be presented on appeal unless good cause is shown.

Can I request an informal review before filing a formal appeal in Clinton County?

Yes, Clinton County offers an informal review process before you file a formal Board of Revision complaint. Contact the Clinton County Auditor's Office at 937-382-2250 to schedule an appointment to discuss your property valuation concerns. During this informal review, you can present initial evidence and potentially resolve the issue without filing a formal complaint. If you're not satisfied with the informal review outcome, you can then proceed to file a formal complaint with the Board of Revision between January 1 and March 31. This informal step can save time and effort while helping you understand the strength of your case before initiating a legal proceeding.

What can I do if I disagree with the Board of Revision's decision in Clinton County?

If you disagree with the Clinton County Board of Revision's decision, you have 30 days from the date of the decision letter to file DTE Form 4 (Notice of Appeal) with either the Ohio Board of Tax Appeals or the Clinton County Court of Common Pleas. You must file the notice with both the Board of Revision and your chosen appellate body within the 30-day deadline or your appeal will be dismissed. The Ohio Board of Tax Appeals can be reached at 614-466-6700 and accepts electronic filings at bta.ohio.gov. This next level of appeal involves a more formal legal proceeding, so many property owners consult an attorney at this stage.
