Cook County Assessor

The site provides information about the Cook County Assessor's Office, which is responsible for assessing all properties in Cook County. You can use this site to look up the assessment and characteristics of your property as well as the other 1.8 million parcels of property in the county. This information can be used for appealing your property's assessed value online. It also contains information regarding property tax exemptions qualifications.

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.
