How to Challenge Your Tax Value in Dayton, OH

You can challenge your property tax value in Dayton, Ohio, by filing a complaint with your county's Board of Revision between January 1 and March 31. To have a realistic chance of success, you must state the value you believe your home is worth and provide evidence showing why the county auditor's value is incorrect.

The strongest evidence is typically a recent appraisal, comparable home sales, photographs showing significant damage or deferred maintenance, repair estimates, or proof that the county has incorrect information about your property. Simply saying your property taxes are too high or that your neighbor's house sold for less is usually not enough.

Step 1: Have a Good Reason

The most important part of the process is having solid evidence to support your request. The Board of Revision isn't looking for opinions—it is looking for proof that your home's market value is different from the value assigned by the county.

Good supporting evidence includes:

• A recent third-party appraisal.
• Comparable homes that recently sold for less.
• Major damage or deferred maintenance the county may not have considered.
• Contractor repair estimates.
• Incorrect county records, such as the wrong square footage or features.

If you're using comparable sales, they should be similar in size, age, style, location, and condition. A local Realtor can often help identify the best comparable sales to support your case.

Over the years, I've helped several homeowners challenge their property tax valuations by providing recent comparable home sales. I don't charge my past clients for this service because I believe taking care of my clients doesn't end at the closing table.

Most recently, I helped a homeowner in Centerville gather comparable sales for his Board of Revision hearing. He used those sales as part of his evidence, and the county agreed to reduce his property valuation, lowering his property taxes. While every case is different and no outcome can ever be guaranteed, having well-selected comparable sales can make a significant difference.

On the other hand, these arguments alone are generally not enough:

• "My taxes are too high."
• "My neighbor's house sold for less."
• "The houses around me are in poor condition."

Without documentation supporting your opinion, your request will likely be denied.

Step 2: File the Complaint

Once you've gathered your evidence, complete the Board of Revision complaint form on your county's website.

You'll indicate:

• The value you believe your home should be.
• Why you disagree with the county's value.
• Supporting documents such as an appraisal, comparable sales, repair estimates, or photographs.

For Montgomery County homeowners, the complaint forms and instructions can be found by visiting the Montgomery County Auditor's website and selecting the Value Dispute tab.

Before submitting your complaint, make copies of everything for your records.

Step 3: Attend the Hearing

If a hearing is scheduled, it typically lasts about 10 to 20 minutes. You'll explain why you believe your home's value should be adjusted and present the evidence you've gathered.

Bring copies of your appraisal, comparable sales, repair estimates, photographs, or any other supporting documentation. Keep your presentation organized and focused. The Board wants to understand why your requested value is supported by the market.

After the hearing, you'll receive the Board's decision. If your appeal is approved, your property's assessed value will be adjusted according to the Board's decision and the applicable tax year.

Final Thoughts

The key to a successful property tax appeal is evidence—not opinion. If you can support your requested value with an appraisal, comparable sales, repair estimates, or documentation of your home's condition, you'll have a much stronger case than someone who simply believes their taxes are too high.

If you need help locating comparable home sales for your property in Dayton, Beavercreek, Centerville, Bellbrook, Kettering, Springboro, Fairborn, or the surrounding Miami Valley, I'd be happy to help. Even if you're not buying or selling a home, having accurate market data can make a meaningful difference when challenging your property's assessed value.
