Where to obtain records

Butler County Treasurer / Property Tax and Tax-Sale Records

Contact the office for delinquent property tax records. This guide does not confirm an online search or current bill list.

How to find the information

The Treasurer publishes a dedicated Property Tax phone, 319-346-6626, separate from vehicle and driver-license desks. Its office is at 428 6th Street, Allison, with mailing address PO Box 327. Request the existing unpaid-tax ledger, dated delinquency publication or sale/certificate history through that tax desk.

For an existing-record request, specify the parcel number, assessment/tax year, payable year and desired as-of date. Distinguish an ordinary collection ledger, dated delinquency publication, tax-sale certificate history and a dated redemption quote. Ask whether special assessments, drainage charges, subsequent taxes, penalties, costs and recent payments are included. Confirm inspection, electronic-copy, certification, research and extract charges with the Treasurer. Assessed values, a payment receipt and an advertised sale amount have different scope from a complete current unpaid balance.

What to ask for

Have the property address, parcel number, owner name, and tax year ready when searching for a particular property.
