The Cook County Board of Review (formerly the Board of Tax Appeals) was created by the 89th General Assembly under statutory changes that established a three-member Board of Commissioners elected from three electoral districts.
Cook County Board of Review
The Board of Review is vested with quasi-judicial powers to hear and decide taxpayer complaints on the value or exempt status of real property, which includes residential, commercial, industrial and condominium property, along with vacant land. Powers granted to the Board include the following:
1.Correct factual mistakes
2.Review Certificates of error
3.Order the Assessor to revise and correct the assessed value of property
4.Review and recommend property for tax exempt status
The Board of Review must also defend appeals made to the Illinois Property Tax Appeal Board (PTAB) from property owners. The Board deals only with assessed valuation before equalization, not with the tax rate or the amount of a tax bill.
