How Butler County Assesses Property

35%of market value

Assessed by: Butler County Auditor's Office

Assessment cycle: sexennial

Notices typically mailed: April-May

Ohio assesses all property at 35% of fair market value. The Butler County Auditor determines your property's market value, then applies the 35% assessment ratio to calculate your taxable assessed value. For example, if your home's market value is $216,520 (Butler County's median), at Ohio's 35% assessment ratio your assessed value would be $75,782. At the county's effective tax rate of 1.44%, this would result in approximately $3,119 in annual property taxes before exemptions or credits are applied.

The Appeal Process

Appeals are heard by the Board of Revision. The Board of Revision consists of the County Auditor, County Treasurer, and a member of the Board of County Commissioners. Hearings are scheduled between April and December after your complaint is filed. You will have the opportunity to present your evidence and explain why you believe your property value is incorrect.

Step 1: Review your property valuation notice received in April-May and gather evidence. Compare your assessed value to recent comparable home sales in your neighborhood using the Auditor's 'Your Neighborhood Sales Dashboard' tool available on the county website.

Step 2: Optional - Request an informal review with the Butler County Auditor's Office before filing a formal appeal. This can sometimes resolve disputes without a formal Board of Revision hearing.

Step 3: Download and complete DTE Form 1 (Complaint Against the Valuation of Real Property) from the Butler County Auditor's website. File the form between January 1 and March 31 along with supporting documentation such as recent comparable sales, independent appraisals, or evidence of property damage.

Step 4: Attend your Board of Revision hearing scheduled between April and December. Present your evidence including comparable sales data, recent appraisals, photos, repair estimates, or independent appraiser testimony to support your claim that your property is overvalued.

Step 5: Receive the Board of Revision's written decision. If you disagree with the decision, you have 30 days to file DTE Form 4 (Notice of Appeal) with either the Ohio Board of Tax Appeals or the Court of Common Pleas for further review.

Step 6: If appeals to the Board of Tax Appeals are unsuccessful, you may further appeal to the Court of Common Pleas or Court of Appeals as a final option.

There are no extensions to this deadline, and mailed complaints must be received by March 31 or bear a USPS postmark of March 31 or earlier. Missing this deadline means you must wait another full year to appeal, and you'll continue paying taxes based on the current assessment.

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

To file a property tax appeal in Butler County, you must complete DTE Form 1 (Complaint Against the Valuation of Real Property) and submit it to the Board of Revision between January 1 and March 31. You can obtain the form from the Butler County Auditor's website at auditor.bcohio.gov. File the completed form along with supporting evidence by mail to Butler County Auditor, Attn: BOR, 130 High Street, 3rd Floor, Hamilton, OH 45011, by email to Auditor@bcohio.gov, or in person at the Auditor's office during business hours. After filing, the Board of Revision will schedule a hearing where you can present your evidence.

What is the homestead exemption worth in Butler County?

The homestead exemption in Butler County shields up to $28,000 of your property's market value from taxation under the standard state program. Butler County commissioners approved a local 'piggyback' homestead exemption for tax year 2025 (payable in 2026) that effectively doubles the exemption, providing protection for up to $56,000 of market value. The savings varies by taxing district but averages around $360 per year across Butler County for the standard exemption, and approximately double that amount with the piggyback provision. To qualify, you must be 65 or older or permanently disabled, with income under $40,000 OAGI.

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

The strongest evidence for a Butler County property tax appeal includes recent comparable sales from your neighborhood showing homes with similar characteristics that sold for less than your assessed market value. You should also consider obtaining an independent professional appraisal conducted within the past year, as this carries significant weight with the Board of Revision. Additional helpful evidence includes photographs documenting property damage or defects, repair estimates for structural issues that affect value, and documentation of market conditions or neighborhood trends. The Butler County Auditor's website provides a 'Your Neighborhood Sales Dashboard' tool to help you identify comparable sales data before filing your appeal.

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

The amount you can save by appealing depends on how much your property is overvalued and whether your appeal is successful. With Butler County's median effective tax rate of 1.44%, every $10,000 reduction in your property's market value saves approximately $50 in annual property taxes (calculated as $10,000 × 35% assessment ratio × 1.44% effective rate). For example, if you successfully reduce your assessed value by $30,000, you would save approximately $151 per year. Statistics show that about 25% of homes in America are overassessed and pay an average of $1,346 too much annually. The actual savings varies significantly based on your specific property and the strength of your evidence.

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

At a Board of Revision hearing in Butler County, you will present your case before a three-member panel consisting of the County Auditor, County Treasurer, and a member of the Board of County Commissioners. The hearing is scheduled between April and December after your complaint is filed. You'll have the opportunity to present evidence such as comparable sales, appraisals, photographs, and expert testimony to demonstrate that your property's assessed value exceeds its fair market value. The Board hears complaints about property values, not the tax dollars you pay. After reviewing your evidence and the county's position, the Board will issue a written decision, which you can appeal to the Ohio Board of Tax Appeals within 30 days if you disagree.

Can I appeal my Butler County property taxes if I already appealed in the last two years?

Generally, no. Ohio law restricts property tax appeals to once every three years unless a new event has occurred such as property damage, fire, flooding, or new construction that affects your property's value. Butler County participates in Ohio's sexennial reappraisal cycle with triennial updates, meaning property values are updated every three years. If you filed an appeal in 2024 or 2025, you typically cannot file again in 2026 unless you can document a qualifying new event that materially changed your property's condition or value. The three-year restriction helps ensure the appeal system focuses on properties with legitimate valuation concerns rather than repetitive filings.

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

Ohio law requires all property to be assessed at 35% of fair market value, and Butler County follows this statewide standard. This means if your home's market value is $216,520 (the county median), your taxable assessed value is calculated as $75,782 (35% of market value). Your property tax bill is then calculated by multiplying this assessed value by the local millage rate for your taxing district. Understanding this 35% ratio is critical for appeals because you need to prove your market value is incorrect, not just that your taxes are too high. For example, to reduce your tax bill by $100 annually at Butler County's 1.44% effective rate, you would need to reduce your market value by approximately $19,841.
