From filing to the final decision
One Fee Per Appeal
You pay only on the first year's savings.
Our Simple Process
You check your property and sign online. We build the case, file it and follow it to a decision.
Check your property free. It takes under a minute.
Sign up online in a few minutes. Nothing to pay up front.
We build the evidence and file your appeal in your township's windows, usually at the Cook County Assessor and then at the Board of Review.
The county decides. If your assessment is reduced, the lower tax shows on your second-installment bill the following year. We invoice our fee, 25% of the first-year savings, after that bill is issued.
If the Board's decision is still too high, we tell you whether an appeal to PTAB, or a tax objection complaint in the Circuit Court, is worth filing; you decide, on the same fee terms. You can appeal every year, not only in your reassessment year.

Each Cook County township has two filing windows per year: one at the Cook County Assessor and a separate one at the Cook County Board of Review. Each window opens when that body announces it for your township and closes on the township-specific last filing date the body sets: about six weeks at the Assessor and about 30 days at the Board of Review. You can appeal every year, not only in your reassessment year.
If you missed both windows this year, a Certificate of Error can still correct a factual error or a missing exemption, and every township's windows open again next year. After the Board of Review decides, you can go to PTAB or to the Circuit Court, not both.
File with the Cook County Assessor while your township's window is open. It opens when the Assessor mails the township's assessment notices and closes on the date the Assessor sets, about six weeks later. The Assessor stage is optional, but filing there gives you two chances at a reduction instead of one, so we usually file at both.
File with the Cook County Board of Review while it is open for your township, about 30 days. You can file whether or not the Assessor lowered your assessment, or even if you did not file there. The Board is independent of the Assessor and decides on the evidence you send.
If the Board of Review's decision is still too high, the appeal can go one step further: to the Illinois Property Tax Appeal Board (PTAB) or, instead, to the Circuit Court of Cook County. That step has a short deadline, so we tell you quickly whether we recommend it.

Why Owners Choose Us
Our Cook County property tax appeal service combines legal strategy and financial analysis to build the case for a lower assessment. We represent both residential and commercial property owners across Chicago and surrounding suburbs.
Nothing up front. Our fee is 25% of your first-year tax savings, invoiced only after your assessment is reduced. If there is no reduction, there is no fee. In all cases, you only pay based on the first year of savings — regardless of how many years the reduction applies. Terms are on the pricing page.
Your appeal is handled by both a licensed Illinois tax attorney and a CPA, so your case covers both the legal arguments and the valuation.
Our founder holds an LL.M. in Taxation, an advanced degree in tax law, as well as a law degree and a CPA license.
We fight your property tax assessment at every level: Assessor, Board of Review, and then the Illinois Property Tax Appeal Board (PTAB) or the Circuit Court. If one venue does not lower your assessment enough, the next one can review it again.
Our office is in Palos Heights, and we represent owners in all 38 Cook County townships, including the City of Chicago. Knowing local assessments, townships and valuation trends helps us find errors and build stronger appeal cases.
Track your Cook County property tax appeal in real time through our secure client portal. Get clear updates from filing to final decision, so you always know the status of your case.
