Hardin County Property Tax Appeal — Ohio

Rob Hartley·Updated April 3, 2026

Hardin County is a rural county located in northwest Ohio with Kenton serving as the county seat. The county has a population of approximately 30,402 residents and includes notable communities such as Kenton, Ada, and Dunkirk. With a median home value of $134,800 and an effective property tax rate of 1.61%, Hardin County's property taxes are notably higher than the national median rate of 1.02%, yet the median annual tax bill of $1,448 remains well below the national median of $2,400 due to lower property values. Property tax appeals are particularly important in Hardin County because the higher-than-average tax rate means even small assessment errors can result in significant overpayments for homeowners.

How Hardin County Assesses Property

35%of market value

Assessed by: Hardin County Auditor

Assessment cycle: triennial

Notices typically mailed: Spring (mid-April)

In Hardin County, property taxes are calculated using Ohio's 35% assessment ratio. This means your assessed value is 35% of your property's market value. For example, if your home's market value is $134,800 (the county median), at Ohio's 35% assessment ratio your assessed value would be $47,180, resulting in approximately $759 in annual taxes at the county's effective rate of 1.61%. Understanding this distinction is critical when appealing your property taxes, as you must challenge the market value, not the assessed value.

The Appeal Process

Appeals are heard by the Board of Revision. After filing your complaint, you will receive a notice of your hearing date before the Hardin County Board of Revision. At the hearing, you'll present your evidence and explain why you believe your property is overvalued, and the Board will issue a written decision.

Review your assessment notice carefully when it arrives in mid-April and compare your property's market value to similar properties in your neighborhood that have recently sold.

Gather compelling evidence including recent comparable sales (ideally within the last 6-12 months), photos of property defects or damage, repair estimates, or a professional appraisal showing your home is overvalued.

Obtain the official complaint form from the Hardin County Auditor's office by visiting in person, calling(419) 674-2239, or downloading it from the county website.

Complete the complaint form fully and accurately, providing your parcel number, contact information, and detailed reasons why you believe your property is overvalued. File this with the Hardin County Board of Revision between January 1 and March 31, 2026.

Attend your hearing before the County Board of Revision with all your evidence organized and ready to present. The Board will review your case and issue a written decision.

If you disagree with the Board of Revision's decision, you may appeal to the Ohio Board of Tax Appeals within 30 days of receiving the Board's decision.

As a final option, you may appeal the Ohio Board of Tax Appeals decision to the Ohio Supreme Court or your local Court of Common Pleas, though this step typically requires legal representation.

What evidence do I need for a Hardin County property tax appeal?

For a successful property tax appeal in Hardin County, you should gather recent comparable sales of similar homes in your neighborhood that sold within the last 6-12 months. The Board of Revision will also consider professional appraisal reports, photographs showing property condition issues or defects, repair estimates from licensed contractors, and documentation of any property damage. Your evidence should demonstrate that your property's assessed market value is higher than what it would actually sell for in the current market. Focus on properties with similar square footage, age, condition, and location. The more comprehensive and recent your evidence, the stronger your appeal will be before the Board of Revision.

How much can I save by appealing my property taxes in Hardin County?

The amount you can save through a successful property tax appeal in Hardin County depends on how much your property's market value is reduced. With the county's effective tax rate of 1.61%, every $10,000 reduction in market value saves approximately $56 per year in property taxes. For example, if your home's market value is successfully reduced from $150,000 to $130,000 (a $20,000 reduction), you would save approximately $112 annually. Given that Hardin County has a higher-than-average effective tax rate compared to the national median of 1.02%, even modest reductions in assessed value can result in meaningful long-term savings. These savings accumulate year after year until the next county-wide reappraisal.

What happens after I file my property tax appeal in Hardin County?

After you file your property tax appeal with the Hardin County Board of Revision, you will receive written notification of your hearing date, typically with at least 10 days advance notice. At the hearing, you'll present your evidence to the Board, which consists of county officials who will review your case and ask questions. The Board will evaluate your evidence against the Auditor's assessment and issue a written decision, which may uphold, reduce, or in rare cases increase your property's valuation. If you disagree with the Board of Revision's decision, you have the right to appeal to the Ohio Board of Tax Appeals within 30 days. The entire process from filing to receiving a decision typically takes several months, and any reduction will apply to the current tax year.

When are property assessment notices mailed in Hardin County?

Property assessment notices in Hardin County are typically mailed in the spring each year, with most notices reaching homeowners by mid-April. These notices show both your property's market value and assessed value (which is 35% of market value), along with an estimate of your property tax bill. Hardin County conducts a full reappraisal of all real property every six years and an update of property values every three years, as required by Ohio law. When you receive your assessment notice, review it carefully and compare your property's value to similar homes in your neighborhood. If you believe your property is overvalued, you must file an appeal between January 1 and March 31 of the following year.

Can I appeal my Hardin County property taxes if I disagree with the Board of Revision decision?

Yes, if you disagree with the Hardin County Board of Revision's decision, you have the right to appeal to the Ohio Board of Tax Appeals within 30 days of receiving the Board's written decision. The Ohio Board of Tax Appeals is a state-level body that conducts an independent review of your case. If you're still not satisfied with the outcome from the Ohio Board of Tax Appeals, you can pursue a final appeal to the Ohio Supreme Court or your local Court of Common Pleas, though this level typically requires hiring a property tax attorney. Keep in mind that each level of appeal has strict deadlines and procedural requirements, so it's important to act quickly and follow all filing instructions carefully to preserve your appeal rights.
