2022 was a property reassessment year for Northfield Township. Cook County follows a triennial reassessment cycle, meaning that a determination of each property’s fair market value and corresponding assessed value occurs once every three year for taxation purposes. This assessed value and exemptions help determine your share of property taxes owed.

The Cook County Assessor mailed the results of the 2022 appeals made to his office by Northfield Township property owners. You can also view your results online at

If you missed your chance to appeal with the Cook County Assessor last fall or you did appeal and believe your assessed value is still not equitable, there will be another opportunity (30-day window) beginning sometime in March 2023 to review your 2022 property assessed value and then file an appeal with the Cook County Board of Review (BOR) 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.

Once the Board of Review appeal window is open, we here at Northfield Township can review your assessment to be sure it is equitable and assist you to file an appeal if helpful.

Watch for BOR appeal window to open during March 2023
