Proviso Township 2021 Assessment Notices Mailed
The Assessor’s Office has mailed 2021 assessment notices to Proviso property owners. You may appeal your assessment each year during the 30-day window which is now open and will close on November 8th. The following cities, towns, and villages are in Proviso Township: Bellwood, Berkeley, Broadview, Brookfield (northwest 1/2), Elmhurst (portion), Forest Park, Hillside, La Grange Park (majority), Maywood, Melrose Park, North Riverside, Northlake (south 1/4), Oak Brook (parts), Stone Park, Westchester, and Western Springs (north portion).
Cook County reassesses properties triennially through a mass appraisal system. Proviso was last reassessed in 2020 and if you appealed and were successful on your 2020 tax year appeal you will see those savings this summer on your 2nd installment property tax bill (the 1st installment bill you recently received is always 55% of the previous year’s total tax).
