How Shelby County Assesses Property

35%of market value

Assessed by: Shelby County Auditor's Office

Assessment cycle: triennial

Notices typically mailed: Late summer to early fall

In Ohio, properties are assessed at 35% of their true market value. This assessed value is then multiplied by the local tax rate to determine your annual property tax bill. For example, if your home's market value is $124,500, at Ohio's 35% assessment ratio your assessed value would be $43,575, resulting in approximately $1,380 in annual taxes at Shelby County's effective rate of 1.11%. Ohio counties conduct a full sexennial reappraisal every six years and a triennial update at the three-year midpoint to ensure fair market valuations.

The Appeal Process

Appeals are heard by the Board of Revision. After filing, the Board of Revision will schedule a hearing and notify you in writing at least 10 days in advance. At the hearing, you'll present evidence supporting your opinion of value. The burden of proof is on the property owner to demonstrate the assessed value is incorrect with clear and convincing evidence. The Board will consider comparable sales, recent purchase documentation, income/expense statements for income-producing properties, and other relevant evidence.

Step 1: Review your property valuation on the Shelby County Auditor's website or property tax bill and identify comparable sales that support a lower value.

Step 2: Gather supporting evidence including recent comparable sales data, professional appraisals, photographs showing property condition, repair estimates, income and expense statements (for income-producing properties), or recent purchase documentation.

Step 3: Complete DTE Form 1 (Complaint Against the Valuation of Real Property) accurately with all required information. Forms can be downloaded from the Board of Revision page on https://co.shelby.oh.us or requested by calling(937) 498-7202.

Step 5: The Board of Revision will schedule a hearing and notify you at least 10 days in advance. Present your evidence at the hearing - the burden of proof is on you to demonstrate that the assessed value is incorrect.

Step 6: The Board of Revision will issue a written decision determining the fair market value of your property. They can affirm, lower, or raise the assessed value based on the evidence presented.

Step 7: If you disagree with the Board of Revision's decision, you may appeal to the Ohio Board of Tax Appeals (BTA) or the local Common Pleas Court. Contact the Auditor's office at(937) 498-7202 for information on filing a BTA appeal.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Shelby County for 2026?

If you file by mail, the United States postmark date counts as your filing date, so a March 31 postmark is acceptable. However, private meter postmarks are not valid. Generally, Ohio law allows only one Board of Revision complaint per parcel in a three-year triennial period unless the property was sold or suffered significant casualty or income loss. Contact the Auditor's office at(937) 498-7202 with questions about filing deadlines.

How do I file a property tax appeal in Shelby County?

Download the form from https://co.shelby.oh.us/198/Board-of-Revision or call(937) 498-7202 to request it.

What is the homestead exemption worth in Shelby County?

The standard homestead exemption in Shelby County exempts up to $25,000 of your home's market value from property taxation, resulting in average annual savings of approximately $400. This exemption is available to homeowners age 65 or older, permanently disabled individuals, and qualifying surviving spouses who meet income requirements (Ohio Adjusted Gross Income of $41,000 or less for 2026 applications). Disabled veterans receive an enhanced exemption of up to $50,000 of market value with no income restriction. For example, if your home is valued at $124,500 and you qualify for the standard exemption, your property would be taxed as if it were valued at $99,500, saving you roughly $400 annually at Shelby County's 1.11% effective tax rate.

What evidence do I need for a successful property tax appeal in Shelby County?

For a successful Shelby County property tax appeal, you need clear and convincing evidence that your property's assessed value is incorrect. The most persuasive evidence includes: (1) Recent comparable sales data from three to five similar properties in your neighborhood that sold for less than your assessment; (2) A professional appraisal dated near January 1 of the tax year showing a lower market value; (3) Photographs documenting property defects, damage, or conditions affecting value; (4) Contractor estimates for needed repairs; (5) Your recent purchase closing statement if you bought the property recently; (6) Income and expense statements if the property generates rental income. The Board of Revision will not consider distressed sales like foreclosures, short sales, or sheriff's sales as valid comparables. Remember, the burden of proof is on you to demonstrate the assessed value exceeds true market value.

How does Ohio's 35% assessment ratio affect my Shelby County property taxes?

Ohio assesses all real property at 35% of true market value, which directly impacts your property tax calculation in Shelby County. This means if your home's market value is $124,500, your assessed value for tax purposes is $43,575 (35% of $124,500). This assessed value is then multiplied by your local tax rate to determine your annual property tax bill. At Shelby County's effective rate of 1.11%, you would pay approximately $1,380 annually. When you appeal your property taxes, you're challenging the market value determination, not the 35% assessment ratio, which is set by state law and cannot be changed. Understanding this calculation helps you determine if your assessment is fair compared to your home's actual market value and comparable properties.

What happens at a Board of Revision hearing in Shelby County?

At a Shelby County Board of Revision hearing, you'll have the opportunity to present oral testimony and documentary evidence supporting your opinion of your property's value. The hearing is a formal legal proceeding where the burden of proof is on you, the property owner, to demonstrate with clear and convincing evidence that the Auditor's valuation is incorrect. You should bring multiple copies of all supporting documents including comparable sales data, appraisals, photographs, and repair estimates. The County Auditor's office will also present evidence supporting their valuation. By law, the Auditor's valuation is presumed correct, so you must overcome this presumption. After reviewing all evidence, the Board will issue a written decision affirming, lowering, or raising your property's assessed value. If you disagree with the Board's decision, you have the right to appeal to the Ohio Board of Tax Appeals or Common Pleas Court.

Can I appeal my Shelby County property taxes if I appealed within the last three years?

Generally, Ohio Revised Code allows only one Board of Revision complaint per parcel in a three-year triennial period. However, there are important exceptions that may allow you to file even if you previously appealed. You can file a new appeal if: (1) The property has been sold since your last filing; (2) The property suffered a significant casualty loss such as fire, flood, or storm damage; (3) The property experienced a significant income production loss if it's income-producing; or (4) A new triennial period has begun following a county-wide reappraisal or update. Additionally, if you filed a complaint and later withdrew it, that withdrawal still counts as an official filing for the triennial period. If you're unsure whether you can file, contact the Shelby County Auditor's office at(937) 498-7202 before the March 31 deadline to discuss your specific situation.

When does Shelby County conduct property reappraisals and updates?

Shelby County follows Ohio's sexennial reappraisal cycle, conducting a full countywide reappraisal every six years and a triennial update at the three-year midpoint. Based on the county's schedule, the most recent sexennial reappraisal occurred in 2023, meaning property values were fully reassessed based on market conditions. The next triennial update is scheduled for 2026, which will adjust values using statistical methods based on overall market trends rather than individual property inspections. The next full sexennial reappraisal will occur in 2029. Assessment notices are typically mailed in late summer or early fall following a reappraisal or update year. Property owners have the right to appeal their assessed values annually between January 1 and March 31, regardless of whether it's a reappraisal year, update year, or off-year. These regular valuation cycles ensure property assessments reflect current fair market values.
