Kendall County, Illinois

Where to obtain records

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

How to find the information

Tax Bill Information separates Tax Bill Search from office contacts: the Collector at 630-553-4124 handles billing/payment questions, Assessments handles valuations, and the County Clerk handles tax rates/levies. Use the bill search for account identification, then request the existing unpaid ledger and the correct Clerk route for sold-tax redemption.

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 Kendall 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.
