Peoria County Tax Sale Instructions to Those Interested in Participating

The information that follows is condensed and brief. For further information, please consult the Illinois Compiled Statues, Chapter 35 (the Revenue Act) Section 200. See the excerpts of the relevant statutes.

Tax Sale

Annually, the Peoria County Treasurer holds a tax sale of all the current delinquent real estate taxes. At the sale, tax buyers will bid on the percentage of penalty that will be charged to the taxpayer. All Tax Buyers must be present to bid. There are no unsold taxes available after the tax sale. Peoria County does use a sealed bid type of sale and information relating to this type can be found here.

  1. All Tax Buyers must register 10 business days prior to the tax sale. The registration must include your name, address, telephone number (home and work), and your social security number or FEIN number.  You can find the tax buyer registration form here.
  2. Only one registration is allowed based on EIN of SSN. All bidders are required to personally attend the sale.
  3. There is a $500 deposit per buyer to be submitted at the time of registration. This deposit will be applied to the amount due on properties the registrant purchases at the tax sale.
  4. If a registrant cannot participate, the registrant may notify the Treasurer's office no later than 5 business days prior to the sale of the name of the substitute person to participate in the registrant's place. No additional deposit is required in this circumstance.
  5. Failure to attend the tax sale will forfeit the deposit.
  6. Tax buyers who attend and fail in their attempt to purchase parcels shall receive a refund of the deposit.
  7. For a fee of 10 cents per parcel, the tax sale list will be available via email starting in late October and will be updated on a regular basis.
  8. Buyers purchasing delinquent taxes will be required to submit certified funds the morning of the tax sale. A deposit of 1-1/2 times what you expect to spend at the tax sale is required before the sale. Tax buyers will be notified of any balance remaining, which will be due the morning following the tax sale.
  9. A list of their purchased delinquent taxes will be available to all Tax Buyers on the morning following completion of the sale.


The penalty starts at 18% per six-month period and decreases as the tax buyers bid competitively against one another. The lowest  percentage is accepted and will be calculated at six-month intervals from the date of tax sale.


The amount of delinquent taxes plus cost of tax sale (currently $123 as stipulated by statute) must be paid by the successful bidder with certified funds within 24 hours.

Redemption Period

If the property is owner occupied, the redemption period is two years and six months. Prior to the expiration of the redemption period, tax deed procedures must be completed. The service of an attorney that is familiar with tax deed procedures is strongly advised. Purchasing taxes at the tax sale does not automatically give the tax buyer any legal right to the property. The redemption period, set by law, must expire without redemption before a tax deed can be issued. Should the tax buyer fail to fulfill the requirements as outlined in 35 ILCS 200/21&22, the tax buyer will lose their money and any interest in the property in question.

Assignment of County Sales

In the absence of a tax buyer's bid, the County of Peoria Trustee enters an automatic bid of 9% every 6 months and becomes the tax buyer.

Trustee-Owned Property for Sale

The Peoria County Trustee, as tax purchaser, does acquire property through the tax deed procedure. Once the property is acquired, the Trustee sells the property at an auction held yearly (Public Auction for Surplus Property). The sale is conducted under the direction and authority of the County Board, which is acting as Trustee for the taxing districts. Parcels are sold to the highest bidder. All necessary research is the responsibility of the potential buyer.

Auction for Surplus Property

The Auction for Surplus Property will be held as a sealed bid auction with the last day to bid being August 26, 2022. The property catalog that lists available property for auction will be available 30 days prior to the auction in the Peoria County Treasurer's office in a limited quantity. The catalog can also be accessed at for an electronic version once it becomes available. The catalogs cost $20 for a printed copy. The catalog will state the minimum bid for each item which is $817.00. Your bid must be equal to or greater than the minimum bid. You only have one chance to bid so we suggest you bid the maximum amount you wish to invest in the property. You do not personally appear at an auction site, you simply submit your bid (included in the catalog or on-line) and payment.  Payment must be made in full with certified funds or personal check. Bids received after the deadline will not be accepted. The proceeds from this sale are distributed to the taxing districts.  Your sealed bid package has to be turned into the Treasurer's office by 5:00 p.m. on August 26, 2022.
