Before you write an offer on a West Loop condo, look at the tax figure on the listing and ask what year it comes from. In Cook County, each year's taxes are billed and paid the following year. The first installment is set at 55% of the prior year's total. The second installment reflects current rates, levies, assessments and exemptions. Any tax figure therefore belongs to a specific tax year and reflects the owner's assessment and exemptions in that year. The Assessor's exemption page points owners to property details and exemption history to check a parcel's record. Compare the listing figure against that record before you treat it as your own future cost.
A booming neighborhood does not lighten the bills of the people who live in it. Fulton Market spent the last several years adding office towers, hotels and apartments to the West Loop's tax rolls. But a West Loop homeowner's bill is not set by how much the neighborhood grew. It is set by a citywide rate, by tax increment financing districts that hold on to the neighborhood's growth, and by commercial appeals downtown. None of the three follows from the construction you can see on Fulton Market.
The seller's tax bill comes with the seller's exemption
The most common gap between the listed tax and your first bill is the Homeowner Exemption. It reduces a property's equalized assessed value by $10,000 for an eligible owner-occupied principal residence. The Cook County Treasurer states that it renews automatically only for properties that were not sold to new owners in the prior year, so new owners need to apply. The Assessor's exemption page ties eligibility to whether you occupied the home as your principal residence on January 1 of the tax year. For tax year 2025, that date was January 1, 2025.
Here is roughly what that is worth. At the 2025 average Chicago tax rate of 6.853%, a $10,000 cut in equalized value comes to about $685 a year. Your actual rate depends on your tax code, so use that as a rough guide rather than a quote. If the listed tax includes the seller's exemption and the first year of your ownership falls between the seller's eligibility and yours, the bill you budgeted and the bill you receive can differ by about that much before anything else changes.
This is general information, not legal, tax or financial advice. Confirm how exemptions and timing apply to a specific property with a tax professional or attorney.
One rate for the whole city, and it went up
The second thing that sets your bill is that Chicago's taxing bodies spread their levies across the whole city's tax base. In its 2025 tax rate report, the Cook County Clerk puts the average Chicago tax rate at 6.619% for tax year 2024 and 6.853% for tax year 2025, a 3.54% increase. The state equalizer moved slightly the other way, from 3.0355 to 3.0300. In the Clerk's "City of Chicago – West" region, the average estimated single-family market value rose 0.55% from 2024 to 2025. The average single-family bill rose 3.96%, from $6,524.61 to $6,782.84.
Those regional figures cover single-family homes and are averages, so they are not a West Loop condo number. They do show the mechanism. Home values in the region were nearly flat, and bills still rose by close to the rate increase. Across the city, the Treasurer's tax year 2025 analysis found the median homeowner bill rose 3.2% to $4,597 for bills paid in 2026. Homeowners covered about three-fifths of Chicago's added $195.8 million. The Treasurer attributes the tilt to commercial and industrial values falling more than 2% while residential values fell 0.7%.
Where Fulton Market's growth actually went
New West Loop buildings did not pull the citywide rate down for everyone.
First, the new value raised the West Loop's own share of the city's bill. A Chicago Sun-Times analysis published in March 2025 tracked five years of tax bills. It found the Near West Side among the areas hit hardest by rising taxes, much of it from new commercial and residential development. The paper credited the growth in ZIP code 60607 to Fulton Market District redevelopment and the Old Post Office. It quoted Civic Federation president Joseph Ferguson: "Some folks say the Fulton Market District robbed the Loop. Others say we built a new community."
Second, a large share of the area's new value sits inside TIF districts. There, the property taxes on growth fund the district instead of the general taxing bodies.
| West Loop tax-base measure | Earlier | Later |
|---|---|---|
| ZIP 60607 total tax billings, five-year span in Sun-Times' March 2025 analysis | $190 million, about 2.8% of city | $313 million, about 3.8% of city |
| ZIP 60606 total tax billings, same span | $382.8 million, 5.6% of city | $502.6 million, 6.0% of city |
| Central West TIF billings, tax years 2023 to 2024 | $47.2 million | $54.0 million |
| Kinzie Industrial Corridor TIF taxes, tax year 2025 | More than $156.7 million |
The Kinzie district was one of only three Chicago TIFs to bill more than $100 million in tax year 2025, per the Treasurer. The City lists the Kinzie Industrial Conservation Area TIF as covering parts of the Near West Side and the Fulton and Randolph market areas, with an expiration of 2034. The Central West TIF runs from Lake Street to Polk Street and from Peoria Street to Western Avenue, and expires in 2036. In August 2026, WTTW reported on a UIC study estimating that TIFs raised Chicago property taxes 13.7% from 2014 to 2023. It also reported that $1.59 billion went into the city's 108 TIF funds in 2024.
So the cranes on Fulton Market do not discount anyone's rate. Until those districts expire, much of the growth they produce stays with the districts.
Downtown's appeals landed on homeowners, including here
The same commercial towers that grew the tax base can also shrink it on appeal. After the Assessor's 2024 Chicago reassessment, the Cook County Board of Review cut commercial assessed values citywide by 17%, or $4.3 billion. It cut residential values by 1%. The Assessor's May 2025 summary shows homeowners' share of assessed value rising from 49% after the Assessor's work to 54% after appeals. The largest commercial cuts came in the three townships that cover downtown. West Chicago township, which includes the West Loop, lost $0.8 billion, or 15%, of commercial assessed value on appeal.
Those appeals hit the bills paid in 2025. The Treasurer reported that Chicago's median homeowner bill for tax year 2024 rose 16.7%, to $4,457. Crain's Chicago Business called it the largest residential property tax bill increase in at least 30 years. The office market under those appeals had not recovered. The Treasurer's report, citing Crain's, put 2025 office vacancy at 28% in a Central Business District that includes the West Loop, Far West Loop and Fulton Market.
Taken together, a West Loop condo owner pays a citywide rate that rose in 2025. The neighborhood's new growth largely goes to two TIF funds that run into the mid-2030s. And homeowners as a group carry a larger share of the city's bill after downtown commercial appeals. None of that shows up in a neighborhood's price trend, which is why the tax line deserves its own review when you compare loft and condo prices in the West Loop.
Dates that affect a West Loop purchase right now

Frequently Asked Questions
Does the seller's Homeowner Exemption carry over when I buy? No. The Treasurer says the exemption renews automatically only for properties not sold in the prior year, so a new owner needs to apply.
Can a West Loop owner file an appeal this fall? West Chicago township's 2026 Board of Review window runs through November 6, 2026. Whether to file depends on the property, and a tax attorney or authorized representative can advise on that.
Will Fulton Market's growth eventually lower West Loop bills? The City lists expirations of 2034 for the Kinzie TIF and 2036 for the Central West TIF. Until then, much of the area's new value pays into those districts. What happens to bills after that depends on future levies and assessments.
A West Loop condo's carrying cost includes a tax bill shaped by rates, exemptions and appeals that a price-per-square-foot comparison won't show.
