Cook County Board of Review Opens 2025 Property Tax Appeals for Group 5
The Cook County Board of Review has opened 2025 property tax appeals for the fifth group. The Board’s deadline to appeal your 2025 assessed value is December 19, 2025. Below are the townships that are currently open in Group 5:
