Submitting Payments by Mail

ATTENTION:  TO AVOID REFUSAL/REJECTION OF PAYMENTS AND LATE PAYMENT STATUTORY INTEREST, individual payments of Cook County property taxes submitted by mail must abide by the following requirements:

• If paying in full, pay only the amount that corresponds to the date that the payment envelope is postmarked by the U.S. Postal Service.
• Submit one tax bill payment coupon or duplicate bill payment coupon and check per Property Index Number (PIN) per envelope. To pay on more than one property, you must submit a separate check with the payment coupon for each property.
• Be sure that your check includes:
  
  
  • Property Index Number (PIN)
  • Taxpayer Name
  • Property Location, including Unit Number
  • Mailing Address
  • Telephone Number
  • Email Address
  • Tax Year/Installment

  This information will help us contact you if there is a question about your payment.

  Sample Check:

  
  
  
• Be sure to write your PIN on the envelope that you submit.
• Send only the tax bill payment coupon with your check. Keep the top portion of the tax bill for your records.
• If you are submitting payment for Tax Year 2023 (payable in 2024) mail to:
  

  Cook County Treasurer
  PO Box 805438
  Chicago, IL 60680-4116
  

Your canceled check is your receipt. Within a week, verify that your check cleared with your bank. You may verify the posting of your tax payment at this website by clicking on "payment status" and entering the 14-digit PIN and security code provided.

Please note that, per Illinois law, only payments mailed through the United States Postal Service in envelopes bearing a United States Postal Service postmark (not postage meter) will be recorded as paid on the date the payment was mailed. By contrast, payments sent by private carriers, such as FedEx, UPS, etc., will be recorded as paid on the date the payment is received by the Cook County Treasurer's Office, not the date the payment was mailed.

Mailed payments may be returned if they lack adequate information for processing, such as the PIN, the original payment coupon, and the identity of the person(s) or entity submitting the payment. Payments issued by foreign banks or foreign bank accounts cannot be processed and will be returned. If a payment is returned, additional statutory interest may accrue.

It is recommended that companies intending to make numerous individual payments, and needing duplicate bills in order to do so, utilize our TPA Program. Please see the TPA site at https://tpa.cookcountytreasurer.com/ for additional information.

Submitting Payments in Person

Submit your original payment coupon and payment for any current tax bill issued by the Cook County Treasurer's Office at any of the nearly 400 Chase Bank locations in Illinois.

It's simple and easy!

For all tax bills issued by the Cook County Clerk's Office (open item and forfeiture redemption), please submit your original delinquent tax bill with payment directly to the Treasurer's Office at 118 North Clark Street, Room 112, Chicago, IL 60602. Chase Bank will not accept payment of open item, forfeiture redemption, or tax sale redemption bills.
