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/Art. 4 heading)
Article 4. Assessment Officials - Other Provisions

35 ILCS 200/4-5

    (35 ILCS 200/4-5)
    Sec. 4-5. State compensation not to affect county compensation. Any additional compensation payable from State funds to any county officer under this Code shall not affect any other compensation provided by law to be paid to the county officer. No county board may reduce or otherwise impair the compensation payable to a county officer because the person receives additional compensation payable from State funds under this Code. However, a county board may include State funds payable under this Code as reimbursements of or contributions to county officer salaries in determining the compensation of a county officer. As used in this Section, "county officer" includes any local assessment officer whose compensation is determined in whole or in part by a county board.

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.

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.
