Cook County Treasurer Maria Pappas recently announced that the second installment payment of property taxes is due August 3 but because of the pandemic, Cook County residents can pay without charge through October 1. Partial payments are accepted. Property owners can pay online at the Treasurer’s website. They can also search for refunds and verify tax exemptions there. To check for information about your property simply enter your address; a Property Identification Number is not required. Any balance due after October 1 will be charged 1.5% per month as required by law.
