Cook County uses a complex property tax assessment system that differs from many other parts of Illinois and the United States. Understanding this system is crucial for Chicago property owners and investors.
Key components of Cook County’s property tax system:
- Classification System: Properties are assigned to different classes with varying assessment levels:
- Residential properties (Class 2): Assessed at 10% of market value
- Commercial properties (Class 5): Assessed at 25% of market value
- Industrial properties (Class 5): Assessed at 25% of market value
- Triennial Reassessment Cycle: Cook County is divided into three assessment districts, with each district reassessed every three years:
- Chicago (City): Last reassessed in 2021, next in 2024
- North Suburbs: Last reassessed in 2022, next in 2025
- South Suburbs: Last reassessed in 2023, next in 2026
- State Equalizer: The Illinois Department of Revenue applies an equalizer (multiplier) to Cook County assessments to bring them in line with the statutory 33.33% of market value.
- Tax Rate Calculation: Local taxing bodies (schools, parks, libraries, etc.) determine their levy needs, which are divided by the total assessed value to determine the tax rate.
- Exemptions: Various exemptions can reduce your assessed value, including:
- Homeowner Exemption
- Senior Citizen Exemption
- Senior Freeze Exemption
- Home Improvement Exemption
- Disabled Persons Exemption
Property Tax Appeal Process:
Property owners can appeal their assessments through:

- Cook County Board of Review: Secondary appeal opportunity if dissatisfied with the Assessor’s decision
- Illinois Property Tax Appeal Board: Final administrative appeal
- Circuit Court: Legal challenge to assessment
Our Chicago tax specialists can help you navigate the property tax appeal process, identify applicable exemptions, and develop strategies to manage your property tax burden effectively.
