Thornton Township 2021 Assessment Notices Mailed
The Assessor’s Office has mailed 2021 assessment notices to Thornton property owners. You may appeal your assessment each year during the 30-day window which is now open and will close on September 09th. The following cities, towns, and villages are in Thornton Township: Blue Island (southern edge), Burnham, Calumet City, Dixmoor, Dolton, East Hazel Crest, Glenwood (northern 1/4), Harvey, Hazel Crest, Homewood (northeast half), Lansing (northern half), Markham (eastern 1/4), Phoenix, Posen, Riverdale, South Holland, and Thornton.
Cook County reassesses properties triennially through a mass appraisal system. Thornton 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).
