    AN ACT concerning revenue.
 
    Be it enacted by the People of the State of Illinois,
represented in the General Assembly:
 
    Section 5. The Department of Revenue Law of the Civil
Administrative Code of Illinois is amended by adding Section
2505-815 as follows:
 
    (20 ILCS 2505/2505-815 new)
    Sec. 2505-815. Property tax system study. The Department,
in consultation with the Department of Commerce and Economic
Opportunity, shall conduct a study to evaluate the property
tax system in the State and shall analyze any information
collected in connection with that study. The Department may
also examine whether the existing property tax levy,
assessment, appeal, and collection process is reasonable and
fair and may issue recommendations to improve that process.
For purposes of conducting the study and analyzing the data
required under this Section, the Department may determine the
scope of the historical data necessary to complete the study,
but in no event shall the scope or time period be less than the
10 most recent tax years for which the Department has complete
data. The study shall include, but need not be limited to, the
following:
        (1) a comprehensive review of the classification
    system used by Cook County in assessing real property in
    Cook County compared with the rest of the State,
    including, but not limited to, a projection of the impact,
    if any, that the assessment of real property in Cook
    County would exhibit if the classification system were to
    be phased-out and transitioned to a uniform level of
    assessment, and the impact, if any, that the Cook County
    classification system has or has had on economic
    development or job creation in the county;
        (2) a comprehensive review of State laws concerning
    the appeal of assessments at the local and State level and
    State laws concerning the collection of property taxes,
    including any issues that have resulted in delays in
    issuing property tax bills;
        (3) a comprehensive review of statewide assessment
    processes, including a comparison of assessment process in
    Cook County and other counties and practices in other
    states that allow for standardized assessment processes;
        (4) a comprehensive review of current property tax
    homestead exemptions, the impact of those exemptions, and
    the administration or application of those exemptions;
        (5) an analysis of preferential assessments or
    incentives, including, but not limited to, the resultant
    economic impact from preferential assessments; and
        (6) a review of the State's reliance on property taxes
    and the historical growth in property tax levies.
    The Department may consult with Illinois institutions of
higher education in conducting the study required under this
Section. The Department may also consult with units of local
government. To the extent practicable and where applicable,
the Department may request relevant, publicly available
property tax information from units of local government,
including counties and municipalities, that is deemed
necessary to complete the study required pursuant to this
Section. Units of local government that are required to submit
property tax information to the Department must do so in a
reasonably expedient manner, to the extent possible, but in no
event later than 60 days after the date upon which the
Department requests that relevant information.
    The Department may complete a preliminary report that may
be made available for public inspection via electronic means
prior to the publication of the final report under this
Section. The Department shall complete and submit the final
report under this Section to the Governor and the General
Assembly by July 1, 2026. A copy of both the preliminary
report, if made available by the Department, and the final
report shall be made available to the public via electronic
means. The Department may allow for the submission of public
comments from individuals, organizations, or associations
representing residential property owners, commercial property
owners, units of local government, or labor unions in Illinois
prior to finalizing the final report under this Section and
after publication of the final report under this Section. If
the Department allows for the submission of public comments,
the Department shall publish via electronic means any and all
materials submitted to the Department.
    This Section is repealed on December 31, 2026.

Effective Date: 1/1/2025
