Why Clients Trust Us?
Our Cook County property tax appeal service combines legal strategy and financial analysis to maximize reductions. We represent both residential and commercial property owners across Chicago and surrounding suburbs.
Pay nothing upfront. 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.
Your appeal is handled by both a licensed Illinois tax attorney and a CPA. This dual expertise ensures your property tax appeal is legally strong and financially accurate, increasing your chances of maximum tax reduction.
Our leadership holds an LL.M. in Taxation, one of the highest levels of tax law education. This advanced expertise allows us to build stronger Cook County property tax appeal cases and achieve better results.
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. This multi-level strategy maximizes your chances of securing the lowest possible property tax.
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.
Firm Leadership
Why hire just a lawyer or just an accountant when you can have both? Work with a trusted Cook County property tax appeal attorney and CPA who brings together advanced legal strategy and precise financial analysis to maximize your tax savings.
If you're overpaying on property taxes in Cook County, a standard approach is not enough. You need a firm that understands both the legal and financial sides of your assessment.
Our firm focuses on Cook County property tax appeals and Illinois property tax appeals, combining legal expertise with detailed valuation analysis to uncover errors, challenge assessments, and build strong cases for reduction.
We approach every property tax appeal with the combined strength of an attorney and CPA, ensuring your case addresses both legal arguments and valuation accuracy. This eliminates blind spots and maximizes your opportunity for a successful reduction.
Appeals before the Board of Review or PTAB demand more than basic representation. As a dual-licensed Cook County property tax appeal attorney and CPA, we present the evidence, challenge flawed valuations, and build compelling cases to maximize your tax reduction.

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.
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 a Board of Review decision on your appeal, the next step is PTAB or a tax objection complaint in the Circuit Court.
File the initial appeal while your township's window is open. The Assessor sets the closing date for each township; the window opens when reassessment notices are mailed. The Assessor stage is optional; a taxpayer may proceed directly to the Board of Review.
File during the Board's session for your township. The Board is a quasi-judicial body that reviews the Assessor's valuation based on the evidence the taxpayer submits. It does not perform an independent appraisal.
After a final Board of Review decision, the taxpayer may file at PTAB within 30 days of the later of the Board’s written decision or the date the Board sends its final action on the township to the Assessor (35 ILCS 200/16-160; 86 Ill. Adm. Code 1910.30), or, in the alternative, file a tax objection complaint in the Circuit Court of Cook County (35 ILCS 200/23-5 et seq.). The two routes are alternatives.
Not open yet? Pre-register and we file the day your township opens.
Statutory references: 35 ILCS 200/16-160 and 86 Ill. Adm. Code 1910.30 (PTAB filing window: 30 days from the later of the Board of Review’s written decision or the date it sends its final action on the township to the Assessor; a mailed petition is filed on its postmark date); 35 ILCS 200/23-5 through 23-25 (Circuit Court tax objection complaints). Specific township windows vary year to year and are set by the Cook County Assessor and the Cook County Board of Review.
