Free to check. Nothing is filed on your behalf, and a verdict of "not worth appealing" is the answer we return most often.
Deadline
30 days from the publication of your TOWNSHIP's assessment roll. Cook reassesses on a rolling three-year, township-by-township calendar, so your window depends on your township and not on the county. Confirm it against your own notice — a late filing cannot be cured.
