Property tax bills for Tax Year 2023 for homeowners in the south and southwest suburbs of Cook County jumped significantly while businesses in the area got big breaks, an analysis by the county treasurer’s office released this morning shows.

That stark disparity is driven by a mix of higher home values, the elimination of a COVID-era assessment reduction and businesses successfully appealing their valuations before the Board of Review, according to the treasurer’s office.
