Cook County Treasurer Maria Pappas will conduct the first sale in more than two years of delinquent Cook County property taxes on Nov. 5, 2021.

About $163.4 million in unpaid 2018 property taxes (that were to be paid in 2019) is due on 36,000 homes, businesses and land. Less than $1,000 is owed on 11,744 properties in Chicago and 7,700 properties in suburban Cook County.

Pappas is sending owners of those properties a certified mailing informing them that their unpaid taxes are scheduled to be sold, which would put a lien against their properties. It is the first step in a process that can end with the loss of a property.
