Cook County Board of Review

Property Tax Assessment Appeals

• Function: A quasi-judicial body responsible for correcting errors in property assessments for Cook County.
• Appeals: Taxpayers can file complaints to contest the assessed value of their residential, commercial, or industrial property.
