Note: If you have purchased tax liens for PINs that have since been divided by the Cook County Assessor's Office, you will not be able to submit subsequent tax payments using this STEPS Site. You will be allowed, as an exception, to make subsequent tax payments for those PINs only in person at our office located at 118 N. Clark St., Room 112, Chicago, IL 60602. You will be required to pay a $5 duplicate bill fee per PIN/Installment.
