Cook County businesses and residents may have sticker shock when their property tax bills arrive in the mail shortly. Some will see their taxes increase. Cook County Treasurer Maria Pappas has been an outspoken critic of property taxes, calling for reforms to how local governments are funded.

Her latest report shows many businesses and some property owners in the south suburbs will shoulder a greater tax burden, despite efforts to provide relief during the pandemic.

"Places like Berwyn, Cicero, saw substantial increases in the amount of taxes requested by the local officials there. And as a result, you're going to see a lot of very sizable increases in the amount that homeowners are being billed in those areas. In some cases, the median increased by more than $1,000, so it's fairly significant and there may be some sticker shock," said Director of Research Hal Dardick.

As for the businesses dealing with that tax hike, the County Assessor's office said many which did not get the COVID-19 reduction did well during the pandemic; adding that other large commercial properties may have been under-assessed under prior administrations.
