    Sec. 16‑5. Information from assessors to board of review and board of appeals.

    (35 ILCS 200/16‑8)
    Sec. 16‑8. Books and records of chief county assessment officer.
    (a) In counties with 3,000,000 or more inhabitants, the chief county assessment officer shall maintain records of the assessed value of each parcel of property and shall enter upon the property record card of each town or city lot or parcel of land the elements (or basis) of valuation and computations that are taken into consideration by the chief county assessment officer in ascertaining and determining the fair cash value of each town or city lot or parcel of land and of each improvement thereon, including the elements (shown by percentages or otherwise) that were taken into consideration as enhancing or detracting elements (such as depth, corner, alley, railway or other elements). The assessment officer shall maintain the records for at least 10 years. Upon request by the board of appeals (until the first Monday in December 1998 and the board of review beginning the first Monday in December 1998 and thereafter), the officer shall immediately furnish all of the requested records to the board. The records shall be available, on request, to the taxpayer. The chief county assessment officer shall certify, in writing, the amount of the assessment to the board. If the records maintained by the chief county assessment officer at the time the assessment is certified to the board under subsection (a) contain none of the elements (or basis) of valuation for the parcel, then any increase by the chief county assessment officer shall be considered invalid by the board acting on a complaint under Section 16‑120; and no action by the board under Section 16‑120 shall result in an increase in the valuation for the parcel for the current assessment year.
    (b) In counties with 3,000,000 or more inhabitants, the notice given by the chief county assessment officer to a taxpayer of a proposed increase in assessment shall designate the reason for the increase. If a taxpayer files an assessment complaint with the chief county assessment officer, the notification to the taxpayer of a determination on the assessment complaint shall designate the reason for the result.
    (c) The provisions of this Section shall be applicable beginning with the assessment for the 1997 tax year.

A board of review or board of appeals may summon any assessor, deputy, or other person to appear before it to be examined under oath concerning the method by which any evaluation has been ascertained, and its correctness. Any person so summoned who fails, without good cause, to appear or appearing refuses to submit to the inquiry or answer questions asked by any member of the board, or any attorney representing the board, shall be guilty of a petty offense.

    (35 ILCS 200/16‑55)
    Sec. 16‑55. Complaints. On written complaint that any property is overassessed or underassessed, the board shall review the assessment, and correct it, as appears to be just, but in no case shall the property be assessed at a higher percentage of fair cash value than other property in the assessment district prior to equalization by the board or the Department. The board shall include compulsory sales in reviewing and correcting assessments, including, but not limited to, those compulsory sales submitted by the taxpayer, if the board determines that those sales reflect the same property characteristics and condition as those originally used to make the assessment. The board shall also consider whether the compulsory sale would otherwise be considered an arm's length transaction. A complaint to affect the assessment for the current year shall be filed on or before the 10th day of August in counties with less than 150,000 inhabitants and on or before the 10th day of September in counties with 150,000 or more but less than 3,000,000 inhabitants, except if the assessment books containing the assessment complained of are not filed with the board of review by the 10th day of July in a county with fewer than 150,000 inhabitants or by the 10th day of August in a county with 150,000 or more but less than 3,000,000 inhabitants, then the complaint shall be filed on or before 30 calendar days after the date of publication of the assessment list under Section 12‑10. The board may also, at any time before its revision of the assessments is completed in every year, increase, reduce or otherwise adjust the assessment of any property, making changes in the valuation as may be just, and shall have full power over the assessment of any person and may do anything in regard thereto that it may deem necessary to make a just assessment, but the property shall not be assessed at a higher percentage of fair cash value than the assessed valuation of other property in the assessment district prior to equalization by the board or the Department. No assessment shall be increased until the person to be affected has been notified and given an opportunity to be heard, except as provided below. Before making any reduction in assessments of its own motion, the board of review shall give notice to the assessor or chief county assessment officer who certified the assessment, and give the assessor or chief county assessment officer an opportunity to be heard thereon. All complaints of errors in assessments of property shall be in writing, and shall be filed by the complaining party with the board of review, in duplicate. The duplicate shall be filed by the board of review with the assessor or chief county assessment officer who certified the assessment. In all cases where a change in assessed valuation of $100,000 or more is sought, the board of review shall also serve a copy of the petition on all taxing districts as shown on the last available tax bill at least 14 days prior to the hearing on the complaint. All taxing districts shall have an opportunity to be heard on the complaint. Complaints shall be classified by townships or taxing districts by the clerk of the board of review. All classes of complaints shall be docketed numerically, each in its own class, in the order in which they are presented, in books kept for that purpose, which books shall be open to public inspection. Complaints shall be considered by townships or taxing districts until all complaints have been heard and passed upon by the board.

    (35 ILCS 200/16‑60)
    Sec. 16‑60. Equalization within counties ‑ Publication and hearing. After notice and hearing as required by Section 12‑40, the board of review may increase or reduce the entire assessment, or the assessment of any class included therein, if, in its opinion, the assessment has not been made upon the proper basis. The board may also equalize the assessment in any multi‑township or township, or part thereof, or any portion of the county.
(Source: P.A. 86‑345; 86‑413; 86‑1028; 86‑1481; 88‑455.)

    (35 ILCS 200/16‑65)
    Sec. 16‑65. Equalization process. The board of review shall act as an equalizing authority, if after equalization by the supervisor of assessments the equalized assessed value of property in the county is not 33 1/3% of the total fair cash value. The board shall, after notice and hearing as required by Section 12‑40, lower or raise the total assessed value of property in any assessment district within the county so that the property, other than farm and coal property assessed under Sections 10‑110 through 10‑140 and Sections 10‑170 through 10‑200, will be assessed at 33 1/3% of its fair cash value.
    For each assessment district of the county, the board of review shall annually determine the percentage relationship between the valuations at which property other than farm and coal property is listed and the estimated 33 1/3% of the fair cash value of such property. To make this analysis, the board shall use at least 25 property transfers, or a combination of at least 25 property transfers and property appraisals, such information as may be submitted by interested taxing bodies, or any other means as it deems proper and reasonable. If there are not 25 property transfers available, or if these 25 property transfers do not represent a fair sample of the types of properties and their proportional distribution in the assessment district, the board shall select a random sample of properties of a number necessary to provide a combination of at least 25 property transfers and property appraisals as much as possible representative of the entire assessment district, and provide for their appraisal. The township or multi‑township assessor shall be notified of and participate in the deliberations and determinations.
    In assessment year 2011, the board of review shall consider compulsory sales in its equalization process.
    The board of review, in conjunction with the chief county assessment officer, shall determine the number of compulsory sales from the prior year for the purpose of revising and correcting assessments. The board of review shall determine if the number of compulsory sales is at least 25% of all property transfers within the neighborhood, township, multi‑township assessment district, or other specific geographic region in the county for that class of property, but shall exclude from the calculation (i) all property transfers for which the property characteristics and condition are not the same as those characteristics and condition used to determine the assessed value and (ii) any property transfer that is not an arm's length transaction based on existing sales ratio study standards (except for compulsory sales). If the board determines that the number of compulsory sales is at least 25% of all property transfers within the defined geographic region for that class of property, then the board of review must determine (i) the median assessment level of arm's length transactions and (ii) the median assessment level of compulsory sales. If the median assessment level of compulsory sales is higher than the median assessment level of arm's length transactions, then compulsory sales shall be included in the arm's length transaction study and the board must calculate the new median assessment level. Assessed values of properties within the specific geographic area for that class of property must be revised to reflect this new median assessment level. The revised median assessment level shall be the basis for equalization as otherwise provided in this Section.
    With the ratio determined for each assessment district, the board shall ascertain the amount to be added or deducted from the aggregate assessment on property subject to local assessment jurisdiction, other than farm and coal property, to produce a ratio of assessed value to 33 1/3% of the fair cash value equivalent to 100%. However, in determining the amount to be added to the aggregate assessment on property subject to local jurisdiction in order to produce a ratio of assessed value to 33 1/3% of the fair cash value equivalent to 100%, the board shall not, in any one year, increase or decrease the aggregate assessment of any assessment district by more than 25% of the equalized valuation of the district for the previous year, except that additions, deletions or depletions to the taxable property shall be excluded in computing the 25% limitation. The board shall complete the equalization by the date prescribed in Section 16‑35 for the board's adjournment, and, within 10 days thereafter, shall report the results of its work under this Section to the Department. At least 30 days prior to its adjournment, the board shall publish a notice declaring whether it intends to equalize assessments as provided in this Section. The notice shall be published in a newspaper of general circulation in the county. If the board fails to report to the Department within the required time, or if the report discloses that the board has failed to make a proper and adequate equalization of assessments, the Department shall direct, determine, and supervise the assessment so that all assessments of property are relatively just and equal as provided in Section 8‑5.

    (35 ILCS 200/16‑70)
    Sec. 16‑70. Determination of exemptions. The board of review shall hear and determine the application of any person who is assessed on property claimed to be exempt from taxation. However, the decision of the board shall not be final, except as to homestead exemptions. Upon filing of any application for a non‑homestead exemption which would reduce the assessed valuation of any property by more than $100,000, the owner shall deliver, in person or by mail, a copy of the application to any municipality, school district, community college district, and fire protection district in which the property is situated. Failure of a municipality, school district, community college district, or fire protection district to receive the notice shall not invalidate any exemption. The board shall give the municipalities, school districts, community college districts, fire protection districts, and the taxpayer an opportunity to be heard. The clerk of the board in all cases other than homestead exemptions, under the direction of the board, shall make out and forward to the Department, a full and complete statement of all the facts in the case. The Department shall determine whether the property is legally liable to taxation. It shall notify the board of review of its decision, and the board shall correct the assessment if necessary. The decision of the Department is subject to review under Sections 8‑35 and 8‑40. The extension of taxes on any assessment shall not be delayed by any proceedings under this Section, and, if the Department rules that the property is exempt, any taxes extended upon the unauthorized assessment shall be abated or, if paid, shall be refunded.

    Sec. 16‑75. Certificates of error. The board of review shall, at any time before judgment, if an error or mistake is discovered (other than errors of judgment as to the valuation), in any assessment, issue to the person erroneously assessed a certificate setting forth the nature of the error and its cause or causes. The certificate when properly endorsed by the chief county assessment officer, showing concurrence therein, and not otherwise, may be used in evidence in any court of competent jurisdiction, and when so introduced in evidence, shall become a part of the court records, and shall not be removed from the files except upon the order of the court.
    After the board of review has issued a certificate of error and it has been properly endorsed by the chief county assessment officer, 2 copies of the certificate shall be made and one copy given to the county clerk and one copy to the collector. The county clerk shall keep records of the changes or corrections made in the certificate and shall certify such corrections to the collector so that he or she can account for the proper amount of taxes chargeable to him or her.

    (35 ILCS 200/16‑80)
    Sec. 16‑80. Reduced assessment of homestead property. In any county with fewer than 3,000,000 inhabitants, if the board of review lowers the assessment of a particular parcel on which a residence occupied by the owner is situated, the reduced assessment, subject to equalization, shall remain in effect for the remainder of the general assessment period as provided in Sections 9‑215 through 9‑225, unless the taxpayer, county assessor, or other interested party can show substantial cause why the reduced assessment should not remain in effect, or unless the decision of the board is reversed or modified upon review.

    Sec. 16‑85. Certification of assessment books. The board of review in counties with less than 3,000,000 inhabitants, shall, on or before the annual date for adjournment as fixed by Section 16‑35, complete its work and make the entries in the assessment books required to make the assessment conform to the changes made therein by the board of review, and shall attach to each book an affidavit signed by at least 2 members of the board, which affidavit shall be substantially in the following form: State of Illinois, County of ....,
    We, and each of us, as a member of the board of review of the county of .... in the State of Illinois, do solemnly swear that the book to which this affidavit is attached contains a full and complete list of all the property in the county subject to taxation for the year .... so far as we have been able to ascertain, and that the assessed value set down opposite the description of a property, is, in our opinion, a just and equal assessment of the property for the purposes of taxation according to law, and that the footings of the columns in the book are correct, to the best of our knowledge and belief.
    Dated ....

In counties with less than 3,000,000 inhabitants, when the books are completed, the board of review shall deliver one set of the books to the county clerk, who shall file it in his or her office; and one set to the chief county assessment officer. All of the books shall be public records. All assessors' books shall be retained for a period of 5 years, after which the County Board may order the officer having custody of the books to dispose of them and to certify that fact, when completed, to the county board. The assessment completed by the board of review and certified to the county clerk, as equalized, shall be the assessment upon which the taxes of that year shall be extended by the county clerk.
