McLean County, Illinois

Where to obtain records

McLean County Treasurer / Collector; County Clerk for sold-tax redemption

How to find the information

Tax Information for Property Owners separates Sold Taxes (delinquent/back taxes), handled by the County Clerk, from current-year collection. Request the Clerk’s dated redemption amount for sold taxes. The Treasurer’s account-information page warns that its web view does not detail who paid or whether payment occurred because the taxes were sold.

To obtain existing unpaid-tax records, provide the parcel/PIN, tax year, payable year and desired as-of date. Specify whether you need current collection history, the annual delinquency publication, tax-sale/certificate history or a dated redemption estimate. Ask whether subsequent taxes, interest, penalties, costs and recent payments are included. Confirm inspection, electronic-copy, research, certification and extract fees with the office. Assessor valuations, ordinary property sales, trustee-auction catalogs and payment receipts do not by themselves certify every unpaid obligation.

What to ask for

“I am looking for publicly available delinquent real-property tax records for McLean County for [tax year]. Which office maintains these records? Is there an online search or downloadable list? If not, how can I request a copy, and what fees apply?”

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

County-specific notes

A bill marked paid in the collection view may not explain the remaining sold-tax obligation. Ask for the underlying account/sale record and current Clerk estimate before drawing that conclusion.
