Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

35 ILCS 200/4-20

    (35 ILCS 200/4-20)
    Sec. 4-20. Additional compensation based on performance. Any assessor in counties with less than 3,000,000 but more than 50,000 inhabitants each year may petition the Department to receive additional compensation based on performance. To receive additional compensation, the official's assessment jurisdiction must meet the following criteria:
        (1) the median level of assessment must be no more
    
than 35 1/3% and no less than 31 1/3% of fair cash value of property in his or her assessment jurisdiction; and
        (2) the coefficient of dispersion must not be greater
    
than 15%.
For purposes of this Section, "coefficient of dispersion" means the average deviation of all assessments from the median level. For purposes of this Section, the number of inhabitants shall be determined by the latest federal decennial census. When the most recent census shows an increase in inhabitants to over 50,000 or a decrease to 50,000 or fewer, then the assessment year used to compute the coefficient of dispersion and the most recent year of the 3-year average level of assessments is the year that determines qualification for additional compensation. The Department will promulgate rules and regulations to determine whether an assessor meets these criteria.
    Any assessor in a county of 50,000 or fewer inhabitants may petition the Department for consideration to receive additional compensation each year based on performance. In order to receive the additional compensation, the assessments in the official's assessment jurisdiction must meet the following criteria: (i) the median level of assessments must be no more than 35 1/3% and no less than 31 1/3% of fair cash value of property in his or her assessment jurisdiction; and (ii) the coefficient of dispersion must not be greater than 40% in 1994, 38% in 1995, 36% in 1996, 34% in 1997, 32% in 1998, and 30% in 1999 and every year thereafter.
    Real estate transfer declarations used by the Department in annual sales-assessment ratio studies will be used to evaluate applications for additional compensation. The Department will audit other property to determine if the sales-assessment ratio study data is representative of the assessment jurisdiction. If the ratio study is found not representative, appraisals and other information may be utilized. If the ratio study is representative, upon certification by the Department, the assessor shall receive additional compensation of $3,000 for that year, to be paid out of funds appropriated to the Department from the Personal Property Tax Replacement Fund.
    For State fiscal years beginning on or after July 1, 2023, the Department shall remit to the applicable township or county the amount required for the additional compensation under this Section. That money shall be deposited by the township supervisor or county treasurer into a fund dedicated for that purpose. The township or county payroll clerk shall pay the bonus stipend to the assessor within 10 business days after those funds are deposited into the township or county fund. The bonus stipend shall not be considered part of the assessor's base compensation and must be remitted to the assessor in addition to the assessor's annual salary or compensation. Beginning July 1, 2023, the township or county shall be responsible for the State and federal income tax reporting and withholding and employer contributions under the Illinois Pension Code, if applicable, on the additional compensation under this Section.
    As used in this Section, "assessor" means any township or multi-township assessor, or supervisor of assessments.

35 ILCS 200/4-25

    (35 ILCS 200/4-25)
    Sec. 4-25. Bond of assessors. Before entering office, every assessor and supervisor of assessments, other than township or multi-township assessors, shall enter into a bond, payable to the People of the State of Illinois in the sum of two thousand dollars, or such larger sum as the county board shall determine, with two or more sufficient sureties.
    The bond of the supervisor of assessments shall be approved by the county board, and bonds of other assessors by the president or chairman of the county board. The condition of the bond shall be that the assessor or supervisor of assessments will diligently, faithfully and impartially perform the duties of the office during the term or portion thereof for which he or she was elected or appointed. The bond shall be filed in the office of the county clerk and recorded in a book to be provided for those bonds. Any taxing district, or person suffering any loss resulting from an assessor's failure to perform any of the conditions of the bond may sue to recover the loss in the name of the People of the State of Illinois.

35 ILCS 200/4-30

    (35 ILCS 200/4-30)
    Sec. 4-30. Oath of assessors. Before entering office, every assessor or supervisor of assessments shall take and subscribe to the following oath, which shall be filed in the office of the county clerk, except the oath of township or multi-township assessors and their deputies shall be filed with their respective town clerks. The oath shall be as follows:

    (35 ILCS 200/5-5)
    Sec. 5-5. Election of commissioners of board of review; counties of 3,000,000 or more.
    (a) In counties with 3,000,000 or more inhabitants, on the first Tuesday after the first Monday in November 1994, 2 commissioners of the board of appeals shall be elected to hold office from the first Monday in December following their election and until the first Monday in December 1998. In case of any vacancy, the chief judge of the circuit court or any judge of that circuit designated by the chief judge shall fill the vacancy by appointment. The commissioners shall be electors in the particular county at the time of their election or appointment and shall hold no other lucrative public office or public employment. Each commissioner shall receive compensation fixed by the county board, which shall be paid out of the county treasury and which shall not be changed during the term for which any commissioner is elected or appointed. Effective the first Monday in December 1998, the board of appeals is abolished.
    The board of appeals shall maintain sufficient evidentiary records to support all decisions made by the board of appeals. All records, data, sales/ratio studies, and other information necessary for the board of review elected under subsection (c) to perform its functions and duties shall be transferred by the board of appeals to the board of review on the first Monday in December 1998.
    (b) (Blank).
    (c) In each county with 3,000,000 or more inhabitants, there is created a board of review. The board of review shall consist of 3 commissioners, one elected from each election district in the county at the general election in 1998 to hold office for a term beginning on the first Monday in December following their election and until their respective successors are elected and qualified.
    No later than June 1, 1996, the General Assembly shall establish the boundaries for the 3 election districts in each county with 3,000,000 or more inhabitants. The election districts shall be compact, contiguous, and have substantially the same population based on the 1990 federal decennial census. One district shall be designated as the first election district, one as the second election district, and one as the third election district. The commissioner from each district shall be elected to a term of 4 years.
    In the year following each federal decennial census, the General Assembly shall reapportion the election districts to reflect the results of the census. In 2021 and any year following the federal decennial census in which the results of the census are not available by March 31, the General Assembly may use other population data, including, but not limited to, the most recent American Community Survey 5-year data, to reapportion the districts. The reapportioned districts shall be compact, contiguous, and contain substantially the same population. The commissioner from the first district shall be elected to terms of 4 years, 4 years, and 2 years. The commissioner from the second district shall be elected to terms of 4 years, 2 years, and 4 years. The commissioner from the third district shall be elected to terms of 2 years, 4 years, and 4 years.
    In case of vacancy, the chief judge of the circuit court or any judge of the circuit court designated by the chief judge shall fill the vacancy by appointment of a person from the same political party. If the vacancy is filled with more than 28 months remaining in the term, the appointed commissioner shall serve until the next general election, at which time a commissioner shall be elected to serve for the remainder of the term. If a vacancy is filled with 28 months or less remaining in the term, the appointment shall be for the remainder of the term. No commissioner may be elected or appointed to the board of review unless he or she has resided in the election district he or she seeks to represent for at least 2 years before the date of the election or appointment. In the election following each federal decennial census and board of review redistricting, a candidate for commissioner may be elected from any election district that contains a part of the election district in which he or she resided at the time of the redistricting and re-elected if a resident of the new district he or she represents for 18 months prior to re-election. The commissioners shall hold no other lucrative public office or public employment.
    Each commissioner shall receive compensation fixed by the county board, which shall be paid from the county treasury. Compensation for each commissioner shall be equitable and shall not be changed during the term for which that commissioner is elected or appointed. The county shall provide suitable office space for the board of review.
    For the year beginning on the first Monday in December 1998 and ending the first Monday in December 1999, and every fourth year thereafter, the chair of the board shall be the commissioner elected from the first district. For the year beginning the first Monday in December 1999 and ending the first Monday in December 2000, and every fourth year thereafter, the chair of the board shall be the commissioner elected from the second district. For the year beginning the first Monday in December 2000 and ending the first Monday in December 2001, and every fourth year thereafter, the chair shall be the commissioner elected from the third district. For the year beginning the first Monday in December 2001 and ending the first Monday in December 2002, and every fourth year thereafter, the chair of the board shall be determined by lot.
    On and after the first Monday in December, 1998, any reference in this Code to a board of appeals shall mean the board of review created under this subsection, and any reference to a member of a board of review shall mean a commissioner of a board of review. Whenever it may be necessary for purposes of determining its jurisdiction, the board of review shall be deemed to succeed to the powers and duties of the former board of appeals; provided that the board of review shall also have all of the powers and duties granted to it under this Code. All action of the board of review shall be by a majority vote of its commissioners.
