Treasurer - Annual Tax Sale

Published by datacatalog.cookcountyil.gov | Cook County of Illinois | Catalog Last Checked: January 31, 2026 at 10:49 AM | Dataset Last Updated: January 27, 2026
Under Illinois law, the Treasurer’s Office is required to hold an Annual Tax Sale. The sale is held once a year, sometime after the Second Installment. If property taxes for the immediately preceding tax year are delinquent on a parcel, they are offered for sale to tax purchasers at the Annual Tax Sale. The buyer is buying a tax lien on the property not the property itself.
