Ohio Property Tax GuideAppeal and Lower Your Ohio Property Tax.
Ohio has one of the most straightforward homeowner appeal systems in the country, one form, one deadline, one hearing. The challenge is that the deadline is March 31, which catches most homeowners off guard every spring.
How the Ohio Complaint Process Works
- Pull your parcel record from the county auditor's website. Confirm acreage, square footage, year built, and any listed improvements.
- Assemble comparable sales from within the past 24 months (Ohio courts allow a wider window than many states).
- Complete DTE Form 1. State your claimed market value and attach evidence.
- File with the county Board of Revision by March 31. Most counties accept online filings.
- Attend your hearing in late spring or early summer. Bring your evidence packet.
- Appeal to the Board of Tax Appeals or Common Pleas Court within 30 days if denied.
Major Ohio Counties, Where to File
- Cuyahoga County (Cleveland): cuyahogacounty.gov/fiscal officer. Online DTE Form 1 filing.
- Franklin County (Columbus): franklincountyauditor.com. Online portal with comp research tools.
- Hamilton County (Cincinnati): hamiltoncountyauditor.org.
- Montgomery County (Dayton): mcauditor.org.
- Summit County (Akron): fiscaloffice.summitoh.net.
- Lucas County (Toledo): co.lucas.oh.us/auditor.
- Stark County: auditor.co.stark.oh.us.
File in the reappraisal year. Ohio's 6 year reappraisal cycle (with a 3 year interim update) means your complaint has a much higher win rate in a reappraisal year, because the assessor is working with fresh but imperfect data. Check your county's reappraisal schedule before filing.
When You Probably Qualify for a Reduction
- Your assessed value jumped significantly in a reappraisal or interim update year
- Comparable sales on your street undercut your current valuation
- Your auditor's parcel record has inaccurate improvements (finished basement, garage, deck)
- Your home has unrepaired structural, roof, or plumbing issues
- You purchased the property below the auditor's valuation within the last 24 months

Start My Ohio Complaint →Ohio Property Tax Appeal FAQ
Will filing a complaint raise my valuation?
In Ohio, a school district or local taxing entity can file a counter complaint seeking an increase if your filed opinion is substantially below market. For typical residential appeals this is rare, but homes over $1M should be strategic about the value they claim.
Can I file if I just bought the home?
Yes, and a recent arm's length purchase price is near decisive evidence of market value in Ohio. If your purchase was below the current valuation, file DTE Form 1 with a copy of your closing statement.
Is the Board of Tax Appeals free?
No. The Ohio BTA charges a filing fee ($100 for residential cases). Common Pleas Court is an alternative, but filing fees are comparable.
How many times per cycle can I file?
Once per triennial period (typically once every 3 years). Filing twice in the same interval requires new evidence of a change in value.
