How often can I appeal?
You can usually file one appeal per tax year during your township’s open filing window with the Cook County Board of Review.
Important points to understand:
Appeals are filed according to the township
Each township has a limited annual filing period
You must file during that open window for the current tax year
Once the window closes, you generally must wait until the next year
Because deadlines change every year and vary by township, always confirm your filing window at:
