Warren County, Illinois

Where to obtain records

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

How to find the information

The Treasurer’s current notice says Warren County will acquire delinquent real-estate taxes as trustee beginning with 2025 payable 2026, while mobile-home taxes remain separate. Its page says post-sale redemptions go directly through the County Clerk and distinguishes annual trustee-parcel sealed bids from the unpaid-tax sale. Request the applicable existing ledger or publication.

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 Warren 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.
