Appealing Your Assessment
Property owners have three venues through which they may appeal their assessments. The first place you may appeal is the Cook County Assessor’s Office. If you do not appeal to the County Assessor, or if the reduction granted is too small, you may then appeal to the Cook County Board of Review. Your last chance for assessment reduction is with the Property Tax Appeal Board (PTAB). However, you may not appeal to the PTAB unless you have already appealed to the Board of Review.
