What is the difference between an appeal at the Assessor’s Office and the Board of Review?
In Cook County, property owners have two separate opportunities each year to challenge their assessment. While the goal of both is to lower your taxes, the strategies and evidence required for each are different.
1. The Cook County Assessor’s Office Appeal: This is the first level of the process. It relies heavily on mass-appraisal data. We focus on:
Data Accuracy: Correcting errors in square footage or property class.
Lack of Uniformity: Using advanced data modeling to find comparable properties assessed lower than yours.
2. The Cook County Board of Review Appeal: If the Assessor does not grant a sufficient reduction, we move to the Board of Review. This is an independent review board, and the process is more formal. Our strategy includes:
Legal Arguments: Our attorneys draft formal briefs to defend your reduction.
Direct Representation: We manage all necessary paperwork and represent your interests throughout the process.
The "Hands-Off" Solution: By pre-registering through our portal, you don't need to track these separate windows. We monitor the deadlines for both the Assessor and the Board of Review and file at both levels automatically to ensure you achieve the maximum possible savings.
