Navigating property tax appeals in Cook County requires keen attention to a variety of important deadlines. These deadlines dictate when you can file an appeal with both the Cook County Assessor and the Board of Review. The process is structured to ensure that property owners have a fair opportunity to challenge their assessments, but keeping track of these dates is crucial for a timely submission.

Key Deadlines to Keep in Mind

For a successful appeal, property owners need to be aware of several critical time frames:

• Open for Filing: This marks the earliest date you can submit your property tax appeal. The window for filing opens at different times for different townships.
• Closed for Filing: No appeals will be accepted after this deadline. It’s imperative to submit your appeal before this date to ensure your case is considered.

Appeal Windows Vary by Township

Cook County is divided into townships, each with its own set of deadlines for filing appeals. These deadlines can vary significantly, reflecting the Assessor’s and Board of Review’s schedules for reviewing property assessments within each township. 

For example, townships such as Barrington, Berwyn, and Bloom have specific open and close dates for filing with both the Cook County Assessor and the Board of Review, often spanning a month or more. This timeframe gives property owners a window to prepare and submit their appeals, with dates ranging throughout the year depending on the township.

City of Chicago District Townships

It’s also important to note that City of Chicago district townships will undergo reassessment as part of the triennial schedule. This periodic reassessment can impact the appeal deadlines, making it even more important for property owners within these districts to stay informed about when they can file an appeal.

Stay Informed and Prepared

Keeping track of these deadlines can seem daunting, but staying informed is key to successfully navigating the property tax appeal process. Planning ahead and preparing your appeal documents early can help ensure that you don’t miss these critical deadlines.

For the most accurate and up-to-date information on filing deadlines for your specific township, property owners should consult the Cook County Assessor’s Office website and resources like Kensington Research & Recovery, which provides a comprehensive listing of deadlines for 2024.
