Sec. 21-205. Tax sale procedures.

(a) The collector, in person or by deputy, shall attend, on the day and in the place specified in the notice for the sale of property for taxes, and shall, between 9:00 a.m. and 4:00 p.m., or later at the collector's discretion, proceed to offer for sale, separately and in consecutive order, all property in the list on which the taxes, special assessments, interest or costs have not been paid. However, in any county with 3,000,000 or more inhabitants, the offer for sale shall be made between 8:00 a.m. and 8:00 p.m. The collector's office shall be kept open during all hours in which the sale is in progress. The sale shall be continued from day to day, until all property in the delinquent list has been offered for sale. However, any city, village or incorporated town interested in the collection of any tax or special assessment, may, in default of bidders, withdraw from collection the special assessment levied against any property by the corporate authorities of the city, village or incorporated town. In case of a withdrawal, there shall be no sale of that property on account of the delinquent special assessment thereon.

(b) Until January 1, 2013, in every sale of property pursuant to the provisions of this Code, the collector may employ any automated means that the collector deems appropriate. Beginning on January 1, 2013, either (i) the collector shall employ an automated bidding system that is programmed to accept the lowest redemption price bid by an eligible tax purchaser, subject to the penalty percentage limitation set forth in Section 21-215, or (ii) all tax sales shall be digitally recorded with video and audio. All bidders are required to personally attend the sale and, if automated means are used, all hardware and software used with respect to those automated means must be certified by the Department and re-certified by the Department every 5 years. If the tax sales are digitally recorded and no automated bidding system is used, then the recordings shall be maintained by the collector for a period of at least 3 years from the date of the tax sale. The changes made by this amendatory Act of the 94th General Assembly are declarative of existing law.

(b-5) For any annual tax sale conducted on or after the effective date of this amendatory Act of the 102nd General Assembly, each county collector in a county with 275,000 or more inhabitants shall adopt a single bidder rule sufficient to prohibit a tax purchaser from registering more than one related bidding entity at the tax sale. The corporate authorities in any county with less than 275,000 inhabitants may, by ordinance, allow the county collector of that county to adopt such a single bidder rule. In any county that has adopted a single bidder rule under this subsection (b-5), the county treasurer shall include a representation and warranty form in each registration package attesting to compliance with the single bidder rule, except that the county may, by ordinance, opt out of this representation and warranty form requirement. A single bidder rule under this subsection may be in the following form:

(1) A registered tax buying entity (principal) may only have one registered buyer at the tax sale and may not have a related bidding entity directly or indirectly register as a buyer or participate in the tax sale. A registered tax buying entity may not engage in any multiple bidding strategy for the purpose of having more than one related bidding entity submit bids at the tax sale.

(2) A related bidding entity is defined as any individual, corporation, partnership, joint venture, limited liability company, business organization, or other entity that has a shareholder, partner, principal, officer, general partner, or other person or entity having (i) an ownership interest in a bidding entity in common with any other registered participant in the tax sale or (ii) a common guarantor in connection with a source of financing with any other registered participant in the tax sale. The determination of whether registered entities are related so as to prohibit those entities from submitting duplicate bids in violation of the single bidder rule is at the sole and exclusive discretion of the county treasurer or his or her designated representatives.

(c) County collectors may, when applicable, eject tax bidders who disrupt the tax sale or use illegal bid practices.

Sec. 21-210. Bids by taxing districts.

Sec. 21-215. Penalty bids. The person at the sale offering to pay the amount due on each property for the least penalty percentage shall be the purchaser of that property. No bid shall be accepted for a penalty exceeding 9% of the amount of the tax or special assessment on property.

Sec. 21-220. Letter of credit or bond in counties of 3,000,000 or more; registration in other counties. In counties with 3,000,000 or more inhabitants, no person shall make an offer to pay the amount due on any property and the collector shall not accept or acknowledge an offer from any person who has not deposited with the collector, not less than 10 days prior to making such offer, an irrevocable and unconditional letter of credit or such other unconditional bond payable to the order of the collector in an amount not less than 1.5 times the amount of any tax or special assessment due upon the property, provided that in no event shall the irrevocable and unconditional letter of credit or such other unconditional bond be in an amount less than $1,000. The collector may without notice draw upon the letter of credit or bond in the event payment of the amount due together with interest and costs thereon is not made forthwith by the person purchasing any property. At all times during the sale, any person making an offer or offers to pay the amount or amounts due on any properties shall maintain the letter of credit or bond with the collector in an amount not less than 1.5 times the amount due on the properties which he or she has purchased and for which he or she has not paid.

In counties with less than 3,000,000 inhabitants, unless the county board provides otherwise, no person shall be eligible to bid who did not register with the county collector at least 10 business days prior to the first day of sale authorized under Section 21-115. The registration must be accompanied by a deposit in an amount determined by the county collector, but not to exceed $250 in counties of less than 50,000 inhabitants or $500 in all other counties, which must be applied to the amount due on the properties that the registrant has purchased. If the registrant cannot participate in the tax sale, then he or she may notify the tax collector, no later than 5 business days prior to the sale, of the name of the substitute person who will participate in the sale in the registrant's place, and an additional deposit is not required for any such substitute person. If the registrant does not attend the sale, then the deposit is forfeited to the Tax Sale Automation Fund established under Section 21-245. If the registrant does attend the sale and attempts, but fails, to purchase any parcels offered for sale, then the deposit must be refunded to the registrant.

Sec. 21-225. Forfeited tax liens and certificates. Every tax lien or certificate for property offered at public sale, and not sold for want of bidders, unless it is released from sale by the withdrawal from collection of a special assessment levied thereon, shall be forfeited to the county, as trustee for the taxing districts, and managed pursuant to Section 21-90. Tax certificates are also forfeited to the county in those circumstances described in subsection (d) of Section 21-310 and subsection (f) of Section 22-40 of this Code.

(35 ILCS 200/21-240)

Sec. 21-240. Payment for property purchased at tax sale; reoffering for sale. Except as otherwise provided below, the person purchasing any property, or any part thereof, shall be liable to the county for the amount due and shall forthwith pay to the county collector the amount charged on the property. Upon failure to do so, the amount due shall be recoverable in a civil action brought in the name of the People of the State of Illinois in any court of competent jurisdiction. The person so purchasing shall be relieved of liability only by payment of the amount due together with interest and costs thereon, or if the property is reoffered at the sale, purchased and paid for. Reoffering of the property for sale shall be at the discretion of the collector. The sale shall not be closed until payment is made or the property again offered for sale. In counties with 3,000,000 or more inhabitants, only the taxes, special assessments, interest and costs as advertised in the sale shall be required to be paid forthwith. Except if the purchaser is the county as trustee pursuant to Section 21-90, the general taxes charged on the land remaining due and unpaid, including amounts subject to certificates of error, not included in the advertisement, shall be paid by the purchaser within 10 days after the sale, except that upon payment of the fee provided by law to the County Clerk (which fee shall be deemed part of the costs of sale) the purchaser may make written application, within the 10 day period, to the county clerk for a statement of all taxes, interest and costs due and an estimate of the cost of redemption of all forfeited general taxes, which were not included in the advertisement. After obtaining such statement and estimate and an order on the county collector to receive the amount of forfeited general taxes, if any, the purchaser shall pay to the county collector all the remaining taxes, interest and costs, and the amount necessary to redeem the forfeited general taxes. The county collector shall issue the purchaser a receipt therefor. Any delay in providing the statement or in accepting payment, and delivering receipt therefor, shall not be counted as a part of the 10 days. When the receipt of the collector is issued, a copy shall be filed with the county clerk and the county clerk shall include the amount shown in such receipt in the amount of the purchase price of the property in the certificate of purchase. The purchaser then shall be entitled to a certificate of purchase. If a purchaser fails to complete his or her purchase as provided in this Section, the purchase shall become void, and be of no effect, but the collector shall not refund the amount paid in cash at the time of the sale, except in cases of sale in error under subsection (a) of Section 21-310. That amount shall be treated as a payment and distributed to the taxing bodies as other collections are distributed. The lien for taxes for the amount paid shall remain on the property, in favor of the purchaser, his or her heirs or assigns, until paid with 5% interest per year on that amount from the date the purchaser paid it. The amount and fact of such ineffective purchase shall be entered in the tax judgment, sale, redemption and forfeiture record opposite the property upon which the lien remains. No redemption shall be made without payment of this amount for the benefit of the purchaser, and no future sale of the property shall be made except subject to the lien of such purchaser. This section shall not apply to any purchase by any city, village or incorporated town in default of other bidders at any sale for delinquent special assessments.

Sec. 21-245. Automation fee. In all counties, each person purchasing any property at a sale under this Code shall pay to the county collector, prior to the issuance of any tax certificate, an automation fee set by the county collector of not more than $10 for each item purchased. A like sum shall be paid for each year that all or a portion of the subsequent taxes are paid by a tax purchaser and posted to the tax judgment, sale, redemption and forfeiture record where the underlying certificate is recorded. In counties with less than 3,000,000 inhabitants:

(a) The fee shall be paid at the time of the purchase if the record keeping system used for processing the delinquent property tax sales is automated or has been approved for automation by the county board. The fee shall be collected in the same manner as other fees or costs.

(b) Fees collected under this Section shall be retained by the county treasurer in a fund designated as the Tax Sale Automation Fund. The fund shall be audited by the county auditor. The county board, with the approval of the county treasurer, shall make expenditures from the fund (1) to pay any costs related to the automation of property tax collections and delinquent property tax sales, including the cost of hardware, software, research and development, and personnel and (2) to defray the cost of providing electronic access to property tax collection records and delinquent tax sale records.

Sec. 21-250. Certificate of purchase. The county clerk shall make out and deliver to the purchaser of any property sold under Section 21-205, or to the county if the lien is acquired pursuant to Section 21-90 and a certificate is requested by the county or its agent, a tax certificate countersigned by the collector, describing the property sold, the date of sale, the amount of taxes, special assessments, interest and cost for which they were sold and that payment of the sale price has been made. If any person becomes the purchaser of more than one property owned by one party or person, the purchaser may have the whole or one or more of them included in one certificate, but separate certificates shall be issued in all other cases. A tax certificate shall be assignable by endorsement. An assignment shall vest in the assignee or his or her legal representatives, all the right and title of the original purchaser.

If the tax certificate is lost or destroyed, the county clerk shall issue a duplicate certificate upon written request and a sworn affidavit by the tax sale purchaser, or his or her assignee, that the tax certificate is lost or destroyed. The county clerk shall cause a notation to be made in the tax sale and judgment book that a duplicate certificate has been issued, and redemption payments shall be made only to the holder of the duplicate certificate.

Sec. 21-251. Registry of owners of certificates of purchase.

(a) The county clerk of each county shall create and maintain a registry system that permanently records the names, addresses, and telephone numbers of owners or assignees of certificates of purchase issued pursuant to any tax sale conducted under this Code. The registry may consist of a single record or a combination of records maintained in paper or electronic form and may include copies of records kept by the county treasurer for other purposes, all to be used as the county clerk deems appropriate to carry out the purposes of this Section. The information in the registry shall be made available to the public.

(b) The county clerk of each county is authorized to promulgate reasonable rules, procedures, and forms for purposes of creating and maintaining the registry and for access to the registry information by members of the public. In counties with 3,000,000 or more inhabitants, any owner of a certificate of purchase pursuant to assignment may elect whether to register that assignment as provided in this Section, but all owners of certificates of purchase shall be subject to the provisions of subsection (d) of this Section. In counties with less than 3,000,000 inhabitants, the county clerk shall provide by rule whether registration of assignments of certificates of purchase shall be elective or mandatory.

(c) The owner of a certificate of purchase pursuant to assignment, in order to register that assignment, shall submit to the county clerk the owner's name, address, and telephone number in accordance with any rules, procedures, and forms promulgated by the clerk. Any registered owner of a certificate of purchase may update the registration at any time without charge by submitting to the county clerk any lawful change of name, address, or telephone number.

(d) If notice is required to be given to the owner of the certificate of purchase in any proceeding, whether judicial or administrative, affecting a tax sale conducted under any provision of this Code, the notice may be directed to the most recent owner of the certificate of purchase appearing in the county clerk's registry under this Section. Any notice that has been directed as provided in this Section shall be conclusively presumed to be properly directed to the owner of the certificate of purchase for all purposes related to the proceeding in which the notice is given. No objection or assertion by any assignee of a certificate of purchase in any proceeding shall be heard on grounds that a notice to the tax purchaser was misdirected, unless that assignee's current and lawful name, address, and telephone number were submitted to the county clerk's registry at the time of the notice in question.

(e) The county clerk may assess an automation fee of no more than $10 to be paid by the owner of the certificate of purchase for each assignment of the certificate that is registered under this Section. The fee shall be collected in the same manner as other fees and costs and shall be held by the county clerk in a fund for purposes of automating his or her office. The fee provided for under this Section shall not be chargeable to the cost of redemption under Section 21-355 nor shall it be posted under Section 21-360 of this Code.
