Understanding the Triennial Reassessment Schedule in Cook County:
Cook County uses a triennial reassessment system, meaning each property is reassessed every three years. The county is divided into three districts:
- City of Chicago
- North Suburbs
- South Suburbs
Each year, one of these districts undergoes a full property tax reassessment. The table above reflects the current and upcoming assessment years, updated automatically to ensure you always have the latest information.
If you’re a property owner in Cook County, it’s essential to know your triennial reassessment year so you can:
Stay ahead of potential increases in property tax liability.
Prepare for changes in assessed value.
File appeals on time if your assessment seems inaccurate.
How to Use This Schedule
Find your property’s location and match it to the district listed. If your reassessment year is coming up, it may be a good time to start gathering documentation, reviewing comparable properties, or consulting a property tax professional.
