By Mail

  • 1st Installment Due Date June 2, 2016
  • 2nd Installment Due Date September 2, 2016
Avoid Late Payments
To avoid state statute penalties, only U.S. Postmarked (not metered) envelopes will be accepted. Must be postmarked prior to or on the due date.

  • To pay by installment - send installment coupon and check prior to the due date.
  • To pay in full - send both installment coupons and check, keeping bottom portion for your records.
  • Because of electronic lock box processing, post-dated or unsigned checks will be processed on the day they are received, which may incur additional fees if returned by your bank.
Special Notes About Checks
When paying by check be sure that the face of your check has the following:   
  •  Name and current address
  • 10-digit Property Index Number (PIN#)
  • Current date (no post-dated checks)
  • Valid signature
  • Made payable to Lake County Collector
Please use the envelopes provided when mailing in your payment.

Return Envelopes

The return envelopes that accompany your tax bill will include the return address of our new P.O. BOX located in Bedford Park, IL. This location was selected as it is the closest Post Office to our Lock Box facility. We are very excited to have this option as we are always looking for ways to improve productivity here at the Treasurer's Office.

If you have misplaced our envelopes, please mail to:
Lake County Collector
18 N County Street
Room 102
Waukegan, IL 60085


Your canceled check is your receipt. Within two weeks, verify that your check clears with your financial institution. In addition, you may verify the posting of your payment on this website, at Payment Status.
