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 and volume number 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 a payment for Tax Year 2018, use the return envelope(s) supplied with your tax bill(s), or mail to:
  

  Cook County Treasurer
  PO Box 805436
  Chicago, IL 60680-4116
  

• If you are submitting payment for Tax Year 2019 (due in 2020), mail to:
  

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

Your payment may be returned:

• If it lacks adequate information for processing, such as:
  • PIN
  • payment coupon
  • identity of the person(s) or entity submitting the payment
• If the payments is issued by a foreign bank or from foreign bank account

If a payment is returned, additional statutory interest may accrue.

Your canceled check is your receipt. Within a week, you may verify the posting of your tax payment by going to “Your Property Tax Overview” and entering your address or 14-digit PIN. You may also verify with your bank that your check has cleared.

• 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.

Companies that make numerous individual payments on multiple PINs are urged to use our Third Party Agent Program. The TPA program is very convenient. It allows you to make current year property tax payments via wire transfer on large numbers of properties.
