Illinois residents pay the highest property taxes in the nation. Illinois Policy Institute research shows Cook County property tax bills have risen 78% since 2007, despite median property values rising just 7.3%.
The treasurer reported last year’s collections were $706 million more, totaling $18.3 billion for the 2023 tax year that was collected in 2024. That 4% increase marked at least the 30th year Cook County property taxes have increased.
This does not include the most recent gouging that we have just experienced the 30% plus increase just because Cook County want ever more of our money, for no additional benefit.
