Cook County Board of Review Property Tax Appeal February 27 – March 28

If Northfield Township residents missed their chance to appeal their 2022 property assessed value with the Cook County Assessor, there is another opportunity to file an appeal with the Cook County Board of Review (BOR), if helpful. 

Northfield Township can review residents’ assessments to be sure they are equitable and can assist with filing an appeal if helpful.

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

There are 3 ways the Township can assist you with your appeal:
