In Cook County, appeal windows don’t open all at once. 🗓️
After the Assessor mails reassessment notices, each of the county’s 38 townships gets its own appeal window, generally open for 30 business days. Deadlines are staggered, so you and a friend a few miles away could have very different dates. Board of Review appeals come later in the year, again township by township.
That’s a lot of dates to track. Cut My Taxes follows every township’s schedule so you don’t miss yours.
