Cook County Tax Incentives
Free Incentive Eligibility Analysis
Cook County’s incentive programs are some of the most valuable economic tools available to commercial and industrial property owners in Illinois — and among the most consistently underused. Most property owners who qualify have never been told they qualify. Many who applied years ago don’t know their incentive is approaching expiration.
We offer a no-cost incentive eligibility analysis for any commercial or industrial property in Cook County. Our analysts review your property’s current classification, use, location, investment history, and assessment to determine which programs apply, what the projected savings would be, and what the application process requires. There are no upfront fees — our compensation comes as a percentage of the tax savings we produce.
Contact us today to find out whether your property qualifies for Class 6b, 7a, 7b, 8, or Class C — and how much you could save starting this tax year.
Ready to challenge your assessment?
No upfront fees. 98% success rate. Contingency basis — you pay nothing unless we reduce your taxes.

Frequently Asked Questions
What is a property tax incentive in Cook County?
A Cook County tax incentive reduces a property’s assessment level below the standard 25% commercial or industrial rate, cutting tax bills by 40–60% for up to 12 years. The major classifications are Class 6b (industrial), Class 7a/7b/7c (commercial rehab/new construction), Class 8 (distressed-area commercial), Class 9 (multifamily affordable), and Class L (landmark).
How does Class 7b differ from Class 7a?
Class 7a covers commercial rehab projects with total development costs between $200,000 and $2 million. Class 7b covers the same project types with costs above $2 million. Both reduce assessment to 10% for 10 years, then 15% in year 11, and 20% in year 12. The threshold drives municipal review intensity, not the benefit itself.
Can I apply for an incentive on an existing property?
Yes — if you substantially rehabilitate it or meet the specific classification criteria. “Substantial rehab” generally means rehab costs exceed 50% of the property’s fair market value before rehab. The work must be meaningful structural or systems improvement, not cosmetic updates. Proper documentation is the difference between approval and denial.
What municipalities support incentives?
Cook County incentive classifications require a municipal resolution supporting the application. Municipalities with pro-development policies (Chicago, Franklin Park, Cicero, Chicago Heights, Harvey, North Chicago, many others) routinely pass resolutions. Some wealthier North Shore communities are more selective. We know which municipalities say yes and which say no.
How much tax savings can I expect from an incentive?
A standard commercial property taxed at 25% of market value receiving a Class 7b drops to 10% for a decade — a 60% reduction in assessment. On a $5M commercial building with an effective tax rate of 3%, that’s roughly $90,000 in annual tax savings, $900,000 over the 10-year incentive period. Industrial Class 6b delivers similar math.
Do I need to file the incentive application myself?
No. We handle the full application: the municipal resolution outreach, the Cook County Assessor’s Office paperwork, the supporting financials, and the ongoing annual filings required to maintain the classification. Most owners don’t know they qualify — the paperwork and deadlines keep owners from pursuing incentives that could save them six figures.
