Kane County, Illinois

Where to obtain records

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

How to find the information

The Treasurer’s current page directs sold-tax redemption information to the County Clerk Tax Extension office at 630-232-5964 and publishes a dated November 16, 2026 transition notice. The Clerk’s Tax Redemption page says it supplies an Estimate of Redemption; sale procedures and delinquent property-list questions go to the Treasurer.

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 Kane 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

The office’s current number differs from older association listings. Ask Treasury for the existing ledger/list and the Clerk for the certificate’s dated redemption amount; do not infer a final balance from a tax-sale announcement. Reviewed October 28, 2026. County notices can change, and older calendars remain on some sites. No taxpayer query, CAPTCHA completion, account registration, record-request submission, bidder enrollment, upload or payment was performed. No owner-list attachments or taxpayer rows are included.
