DeKalb County, Illinois

Where to obtain records

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

How to find the information

The Treasurer’s sale FAQ says a copy of the lien list is made available before the sale and directs redemption questions to the County Clerk at 815-895-7149. Use the Treasurer’s current property-tax information route for an account, or request the particular existing list/ledger with tax year and as-of date.

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 DeKalb 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 FAQ still shows an October 27, 2025 sale date. Treat that as older guidance, confirm current procedures and distinguish assignable county-trustee certificates from all unpaid parcels. 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.
