A study from the Cook County Treasurer's Office found nearly $2 billion in property taxes shifted from county businesses to the lowest income homeowners over just three years.

Chicago had some of the worst disparities in the county, with businesses’ tax bills dropping nearly 20% while residential bills increased by more than 16% during the 2021 to 2023 reassessment cycle.

Cook County homeowners’ bills grew by a total of about 7% over the span of the report, and the increases fell more on lower-income Black and Latino taxpayers.
