About Us

Chicago Property Tax Group is a data-driven property tax appeal firm representing commercial, industrial, multifamily, and residential owners across Cook County. Our team combines deep assessment expertise with technology and analytics to deliver measurable reductions at every level of appeal.

Our Approach

We pursue appeals at the Cook County Assessor’s Office, the Board of Review, and beyond when warranted. Our analysts build every case on the Assessor’s own valuation methodology, uniformity comparables, and income-based analysis — the same tools used by the County itself. No upfront fees. Contingency-based. You only pay when we win.

Why Owners Choose Us

• 98% success rate across thousands of appeals filed.
• Full-cycle representation — from initial filing through Board of Review and PTAB when appropriate.
• Technology-first — proprietary comps engine, automated valuation modeling, and real-time Cook County data.
• Specialists, not generalists — property tax is the only thing we do.

Service Area

We represent owners across all 38 Cook County townships, with deep coverage of Chicago, the North Shore, the West Suburbs, the South Suburbs, and the Northwest corridor. Whether you own a single-family home, a strip center, a downtown office tower, or an industrial park, our team has handled it.
