Cook County Board of Review

The Board of Review is a separate, quasi-judicial agency independent of the Assessor.  The Cook County Assessor initially sets the valuation for tax purposes on all of the more than 1.8 million parcels of real estate located in Cook County.   When each township reassessment is completed, the Board of Review opens to allow property owners to appeal the assessment set by the Assessor.   The Board decision sets the final county valuation on the property for that tax year.
