A 32nd year of rising property taxes

Cook County property taxes are going up again for the vast majority of homeowners and business operators, who will finally get their bills next month after another round of delays. Of the 1.8 million bills set to hit mailboxes Sept. 1, about 1.3 million residences and 100,000 businesses will see an increase, according to Cook County Treasurer Maria Pappas’ annual analysis.

The total property tax bill for every city, town, school district and other taxing body across Cook County is more than $19.9 billion — an increase of about $744 million (or 3.9%) compared with last year. It’s the 32nd straight annual increase, according to the report. Nearly all taxing agencies across the county raised their property tax levies this year, the analysis found. About 60% increased them by more than the 3.1% rate of inflation.

Homeowners bear the brunt

Of that new sum, homeowners will pay nearly $600 million, while business properties like offices, factories and big apartment buildings will pay the rest. The burden has been shifting from commercial to residential properties for years, a trend the new analysis says continues. Commercial property values increased by 0.2%, not nearly enough to offset a rise in property values for homeowners, whose bills continued to outpace the 2.7% inflation rate. The tax levy increased by nearly 4% last year.

It’s a continuation of a yearslong trend of the property tax burden shifting from downtown to the city’s neighborhoods, and even suburban residential properties. The COVID-19 pandemic reduced occupancy in many downtown buildings, leading to dips in property values and businesses’ tax bills dropping nearly 20%. In the meantime, residential bills increased more than 16% in the 2021 to 2023 reassessment cycle — and hundreds of thousands of homeowners saw even larger increases.

The share of the tax burden taken on by residential property owners, who were on the hook for about 58% of the tax burden in 2025, has stayed relatively the same since the last round of bills. But residential properties countywide gained 6.84% in value, increasing their tax bills by 5.34%, or a collective $600 million, between 2024 and 2025.

North suburbs see the biggest jumps

The biggest changes will be felt in suburban communities north of North Avenue, whose properties were reassessed in 2025. Growth in home values there “significantly outpaced” those for businesses, the report said, shifting 2% more of the region’s overall tax burden onto homeowners. Unlike the major spike last cycle that saw a historic 15.7% increase in median bills across the northern suburbs, the median tax bill for homeowners there climbed by 6.7% this year to $8,007, per the analysis. For multifamily buildings, the median bill went up by 3.5% to $26,772. The median commercial building bill, meanwhile, dropped by 3.5% to $28,253.

It’s the fifth year in a row the higher tax burden has landed on homeowners compared with business properties. After appeals, the final residential share for homeowners in the north suburbs rose to 64.5% from 62.4% the year before, according to the Tribune. Assessor Fritz Kaegi said the burden shift was dramatic this cycle due to reforms in his office and the Board of Review. Homes in the north suburbs saw the largest spike, nearly 10%, or about a $360 million increase.

Chicago and south suburbs see mixed results

Chicago’s residential properties bore 20% of the total increase, about $120 million. It comes after Black neighborhoods on the South and West sides saw the sharpest increases in their 2024 tax bills. Bridgeport and Logan Square both saw median tax bill increases of $274 each in 2025, while West Town and North Center saw median increases over $350. But the largest median tax bill increases proportionally were seen in Douglas, which saw tax bills jump 6.23%. Uptown and Englewood followed with 5.48% and 5.21% increases respectively.

The south suburbs also saw increases, with taxes rising $177.2 million, or 3.9%, with residential bills up 3.8% and businesses up 4.3%, per the Tribune. Chicago’s overall property taxes rose $196 million, or 2.2%, with homeowner taxes up $120.9 million, or 2.7%, bringing the median homeowner bill to $4,597.
