Cook County Board of Review Opens 2025 Property Tax Appeals for Group 2B
The Cook County Board of Review has opened 2025 property tax appeals for the second group. The Board’s deadline to appeal your 2025 assessed value is September 16, 2025. Below are the townships that are currently open in Group 2b:
