Butler County Overview
Butler County Tax Assessment System
The Butler County Auditor is the chief assessor for all real property. You can search for any parcel by owner name, street address, or parcel number. The auditor's database shows the legal owner name, mailing address, date of last transfer, parcel ID, and legal description. Each record also includes the lot size, acreage, and land use class. Values are broken into land value, improvement value, and total appraised value.
Butler County follows the six-year reappraisal cycle required by ORC Chapter 5713. Triennial updates adjust values at the midpoint. The median listed home price in Butler County is around $310,000, with median sale prices in the $297,000 to $305,000 range. These figures drive the appraisal process. The auditor uses recent sales data, property features, and location to set market values. The assessed value is 35% of market value.
The Butler County Auditor's website provides an online property search tool. Below is a screenshot of the Butler County Auditor's portal for looking up property tax records and assessment data.
This portal lets Butler County property owners and the public search all 160,000 parcels for tax and assessment details.
Butler County Property Tax Rates
Tax rates in Butler County vary by district. West Chester Township, Hamilton, Middletown, Fairfield, and other areas each have their own mix of levies. School levies make up the biggest share. Fire, police, library, and county levies round out the total. Rates are in mills, with one mill equaling one dollar per thousand dollars of assessed value.
House Bill 920 keeps your bill from spiking when values rise. The auditor applies reduction factors to existing levies after each reappraisal. New levies from recent elections keep their full voted rate. ORC Chapter 5705 governs levy authority in Ohio. Butler County voters regularly see school and service levies on the ballot. The auditor certifies final rates before the treasurer sends out bills each December.
Note: Butler County tax rates differ significantly between city districts and rural township areas.
Filing Appeals in Butler County
Butler County property owners can file a complaint with the Board of Revision if they believe their value is wrong. The filing period runs January 1 through March 31 each year. Use DTE Form 2. You can only file once every three years per property unless a new reappraisal changes your value.
The Board of Revision in Butler County consists of the auditor, treasurer, and a commissioner. Hearings happen in the spring. You need evidence. Comparable sales from the area are the strongest form of proof. A recent appraisal from a licensed appraiser also works. If you purchased the property recently, the sale price can be used as evidence of current value. Decisions can be appealed to the Ohio Board of Tax Appeals under ORC Chapter 5715.
Butler County Exemptions and Credits

The homestead exemption removes up to $25,000 of market value for seniors 65 and over or permanently disabled homeowners. Veterans with 100% service-connected disabilities can exempt up to $50,000. These programs directly lower your tax bill.
The owner-occupied credit gives 2.5% off the tax bill for homeowners who live in their property. The non-business credit (10% rollback) applies to residential property.
