Appealing Your Assessment
When Should I File an Appeal?
An appeal is a formal request for the review of your property’s assessment. An appeal may be filed within 30 calendar days after you receive your “Notice of Proposed Valuation Assessment”. The last date to file an appeal will be printed at the bottom of your notice. You may file an appeal to get your assessment reduced, if you feel your residential property has been over-assessed for any of the following reasons:
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.
