Pre-Payments

Due to the exceptionally high volume of incoming prepayments, we ask that you allow two to three weeks for your prepayment to be processed. We appreciate your patience. 

The Pre-Payment option is now closed.



  • Prepayments can be made for Tax Year 2017 normally due and collected in Calendar Year 2018.
  • The maximum amount we can accept is the total tax due in Calendar Year 2017.  Lesser amounts are acceptable. No cash is accepted at this time.
  • We are accepting Prepayments through December 29.  Prepayments received by mail postmarked December 29 or earlier will be accepted.
  • Checks should be made payable to the Lake County Treasurer.
  • Please write the property PIN# and “2017 Prepayment” on your check.
  • Online bill-pay payments made through your bank’s online bill pay service are now being accepted.
  • Payments may be left in a drop box outside the north entrance of the Lake County Court and Administrative Complex, 18 N. County St., Waukegan. The box will be emptied regularly. 
  • Due to the high volume of prepayments, it is likely that longer than normal processing times may be encountered when making payments and receiving receipts.
  • Receipts will be given to taxpayers who pay in person and will be mailed to taxpayers paying by mail, electronically or via the drop box.
  • We strongly recommend that you consult with your accountant or another tax professional before making your prepayment.
If your prepayment is to be mailed or delivered by an overnight delivery service, e.g. UPS or Federal Express...
Please mail payments to:

Lake County Treasurer’s Office
18 North County Street, Room 102
Waukegan, IL 60085

     

    • DO NOT USE ENVELOPES THAT WERE SUPPLIED WITH YOUR NORMAL TAX BILL.  THEY WILL BE DIRECTED TO THE BEDFORD PARK POST OFFICE BOX AND DELIVERY WILL BE DELAYED.
  • Note: Refunds will be given only if the taxes calculate less than the Pre-Paid amount.

We appreciate your patience through this process.
