Information about the Annual Tax Sale

The Tax Sale will be held on November 17, 2022 and 18th, if necessary in the auditorium at 421 North County Farm Road, Wheaton, Illinois 60187. 

    In Response to the pandemic, the DuPage County Treasurer will be using a new system names R.A.M.S. 2 (Randomized Auction Management System) which will allow us to collect bids from the tax buyers without having them sit together in a room and place bids on our laptops. The tax buyers must attend the Tax Sale in order to submit their bid.

    For information regarding the R.A.M.S. 2 process go to

    A list of delinquent parcels will be published in local newspapers in October. An electronically transmitted Tax Sale list of the delinquent parcels will be available for purchase by registered tax buyers at a cost of $250. Information contained on the Tax Sale list includes the permanent parcel number, the assessee name, the delinquent tax amount, the state equalized value, and a column for your buyer code and percentage bid. Purchase of the list is not a requirement for attending the Tax Sale. Comment Software will not be available for the R.A.M.S. 2 system as it will not be needed.  If you do not purchase the tax sale list from the County, you will still receive a list with only the parcel number and sale amount and not the additional information from the full list. There will also be the same empty columns for the buyer code and percentage bid so that you can bring a file on a USB drive for us to import at the sale. The buyer code comes from the county and is the same code you would normally sign in with on the laptops. The Tax Sale list provided to the tax buyers is for the sole purpose of the delinquent property Tax Sale. Use of this information for any other purpose is strictly prohibited. The County Treasurer reserves the right to deny sale of the list to any tax buyer.

    The difference from previous years lies in how the tax sale is conducted. With the R.A.M.S. 2 system, on the day of the sale we will collect the bids for each registered buyer by having their bidder bring a USB Drive to the tax sale with a file that contains their percentage bids for each parcel.  Once all the bids for each registered tax buyer in attendance are loaded into our system, we will process the sale.  Each parcel will be awarded to the lowest bid for a particular parcel.  If there are multiple lowest bids, a random lowest bid is selected.  The processing should only take a few minutes.

    A tax buyer must attend the Tax Sale in order to bid.  Payment of purchases (delinquent taxes + interest + costs of $104.00 per parcel) must be made by cash or cashier's check the day after the Tax Sale held on November 17, 2022. The legal requirements to purchase at the Tax Sale and procedures that must be followed to obtain a tax deed are outlined in the Illinois Compiled Statutes Chapter 35, Act 200, Article 21, available at public libraries or on the internet at Knowledge regarding procedures and statutory requirements is the tax buyer's responsibility.

    The bid represents the rate of interest that would be earned by the tax buyer on the purchase amount during each six months of the redemption period, if the owner redeems the sale. By law, the maximum interest rate bid is 9%. The sale is to the tax buyer who bids the lowest percentage of interest. In the last several years, the average successful bids ranged from 0% to 4%.

    After the Tax Sale, the tax buyer is issued a certificate of purchase, which represents a lien on the property. The property owner has a 2 to 2½ year redemption period, depending on property classification. If the tax lien is not redeemed by the owner, the tax buyer must petition the circuit court for a tax deed after first fulfilling all of the legal requirements. The tax buyer may also pay all unpaid taxes for the next two subsequent years at a specified time and record the payments against the Sale. See Subsequent Tax Payment Information.

    In cases where there are no bidders on a parcel, the County, as Trustee for all taxing bodies, becomes the tax buyer at 9%. The County's certificates are available for purchase by tax buyers in the amount that the County paid, along with the 9%. A list of available parcels is available from the Treasurer's office. Please direct inquiries concerning purchasing County certificates to the DuPage County Clerk. There are no forfeitures (unsold parcels) available after the Sale for over-the-counter purchases.
