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:

  • Elk Grove
  • Lakeview
  • Lyons
  • New Trier

Assessments can be appealed every year, regardless of when a township was reassessed. If you missed your appeal opportunity at the Assessor’s office earlier in the year, or if you did appeal and weren’t satisfied with the result, you have a second opportunity to appeal at the Board of Review. Appealing your home’s 2025 assessed value is the only way to achieve property tax relief on your second installment property tax bill in the fall of 2026, other than selling your home or claiming a new exemption.
