Assessor - Property Tax-Exempt Parcels

Parcels with property tax-exempt status across all of Cook County per tax year, from Tax Year 2022 on, with geographic coordinates and addresses.

As of 2017 owner names in this dataset are no longer being regularly updated. We are trying to figure out a solution to this problem.

Properties of religious, charitable, and educational organizations, as well as units of federal, state and local governments, can be eligible for exemption from property taxes. The Illinois Department of Revenue (IDOR) ultimately grants qualified organizations with property tax exempt status, with additional administration by the Board of Review and/or Assessor. Learn more here, and see the Assessor's guidance for religious organizations here.

When working with Parcel Index Numbers (PINs) make sure to zero-pad them to 14 digits. Some datasets may lose leading zeros for PINs when downloaded.

Additional notes:

  • Parcel entroids are based on Cook County parcel shapefiles.
  • Newer properties may be missing a mailing or property address, as they need to be assigned one by the postal service.
  • Exempt status for parcels changes regularly depending on the use and owner of a given parcel. Please contact if you need additional information about parcels excluded from this dataset.
  • Data will be updated monthly.
  • This dataset contains data for the current tax year, which may not yet be complete or final. Assessed values and property tax-exempt status for any given year are subject to change until review and certification of values by the Cook County Board of Review, though there are a few rare circumstances where values may change for the current or past years after that.
  • Rowcount for a given year is final once the Assessor has certified the assessment roll all townships.
  • Current property class codes, their levels of assessment, and descriptions can be found on the Assessor's website. Note that class codes details can change across time.
