2026: The Triennial Reassessment of the South and Western Suburbs
With three Townships reassessed so far, the average south and western suburban homeowner saw their taxable values jump by 25% as a result of the 2026 Triennial.
This level increase will doubtless result in double-digit property tax bill growth as compared to your bills from 2026.
To the good, the Assessor is opening Townships for appeal and you can sign up quickly and easily with competent representation on this site.
In fact, a recent study by an independent analyst found PTS' appeal success rate fully doubled that of all other residential practitioners: 63% versus 28%. Do it yourself self-appealers fared even worse, with a success rate of a mere 4%.
The average property in River Forest, the first reassessment Township of the bunch, saw a massive spike to its taxable value of 29%.
In addition to the reassessed Townships of Riverside, River Forest, and Oak Park, the County looks to reassess Berwyn, Bloom, Bremen, Calumet, Cicero, Lemont, Lyons, Orland, Palos, Proviso, Stickney, Thornton, and Worth in 2026.
Now is the perfect time to register if you want to ensure your new tax assessment is fair and you owe no more than necessary on your upcoming bills.
IMPORTANT NOTE:
Potential clients who receive our marketing material but miss their Township's Assessor deadline, worry not! The Assessor is the first appeal deadline, not the only. You can still register for the Board of Review. If you miss the Board of Review deadline, our system will automatically set up an appeal for the next available window.
Potential clients may do so anytime here.

The properties below represent a few of the many tax reductions from the our appeals and the grounds on which they were based. File your property tax assessment appeal today.
An owner’s house is exactly the same size, age and style as four of his neighbor’s houses, but he pays 25% more in taxes. This lack of uniformity is a sign that the property is being over-taxed. Contact our property tax appeal advisors today.
LEARN MOREA couple purchased a home for $300,000 in an arm’s-length transaction, but the Assessor estimated the market value at $360,000 - a full $60,000 above the actual price. This is a sign that the owners will be paying more than they should in taxes. Contact our property tax appeal advisors today.
LEARN MOREA house is listed at 1700 square feet of living space, but the Assessor shows it at 1900. When the Assessor measurements show a higher square footage than actual, an owner is paying tax on more house than she owns.
LEARN MOREProperties that are uninhabitable while undergoing major reconstruction due to heavy winds, fire, massive flooding, building code violations or a full upgrade of the building are often deemed uninhabitable by the city. These are grounds for a tax reduction.
