COUNTY AS TAX BUYER: Whenever the delinquent tax amount of a parcel is offered for sale and there are no other bidders, the County of DuPage, as Trustee for all taxing bodies, will bid 18% and become the owner of the certificate. This eliminates forfeitures. After the sale, these certificates can be purchased from the DuPage County Clerk.

DEPOSITS/PAYMENTS: Only cash or cashier's checks made payable to the DU PAGE COUNTY COLLECTOR are accepted.  Personal checks, business checks, third party checks, etc. will not be accepted.  A separate payment method will be required for each registered buyer code.

$  10.00   for Costs
      4.00   for Sales Certificate
    20.00   for Tax Sale Indemnity Fund

Cancellation of any tax buyer's purchases could extend the tax sale; therefore, please contact our office for information regarding an additional day of tax sale.
