Hani Khatib is a rare combination of tax attorney, certified public accountant and LL.M. in Taxation, with over 25 years of experience dedicated to property taxation, financial analysis and legal advocacy. A lifelong Cook County resident, he built Cook County Tax Appeals to give local property owners a true advantage: deep local insight combined with legal and financial expertise, on a fee that is paid only when an assessment is actually reduced.
How the firm works
Every Cook County appeal is filed township by township, in a window of about 30 days, first at the Assessor and then at the Board of Review. The firm checks a parcel against the county's own data on comparable homes, files where the evidence supports a reduction, and takes the case through both venues and, where warranted, the Illinois Property Tax Appeal Board. The fee is 25% of the first year's savings; if the assessment is not reduced, there is no fee. See the attorney service page for what representation involves at each venue, and the pricing page for the fee terms.
What he writes about
The guides and township reports on this site are written from the county's published files: appeal outcomes by venue and township, reassessment changes, tax rates, and the exemption rules as the Assessor states them. Every outcome figure is county-wide data for all appellants, and every post says so.
