2020 Assessments Now Available on Our Web Site

Our 2020 Property Assessments are finalized and available to the public. Our Annual Township Equalization Factor from DuPage County is 1.0406 (4.06%). The 2020 assessments will be used to calculate property tax bills payable in 2021.

All 2020 assessment changes for reasons other than the Annual Township Equalization Factor were published in the July 17th edition of the Carol Stream Suburban Life and Addison Suburban Life newspapers; the owners of these properties were also mailed a Change of Assessment Notice by DuPage County.

Additionally, July 17, 2020 commences the annual 30-day Assessment Appeal filing period with the DuPage County Board of Review (BOR). The deadline to file a 2020 Assessment Appeal with the DuPage Board of Review for any property in Bloomingdale Township is August 17, 2020.
