Paying Real Estate Taxes By Mail

Through September 30, 2021 full installment payments should be mailed using the pre-addressed envelope enclosed with the real estate tax bill to the payment center at:

DuPage County Collector, Bill Payment Center, P. O. Box 4203, Carol Stream, IL 60197


After September 30, 2021, payments and correspondence should be mailed to the Treasurer's office at:

DuPage County Collector, 421 N. County Farm Road, Wheaton, IL 60187-2553


After October 29, 2021, all payments of the 2020 real estate tax bill must be made by cashier’s check, cash or money order.


Both the 1st and 2nd installment payments should include the full payment amount (plus any late payment penalties) and the appropriate payment coupon for proper processing. To ensure correct application of the payment, the check should be made payable to the "DuPage County Collector" and the property index number (a/k/a parcel number) be written on the face of the check. Each payment should be received by the DuPage County Collector's office on or before each due date to avoid penalty charges of 1.5% per month (United States Postal Service postmark acts as a proof of receipt for mail).
