Introduction: Why Commercial Property Owners in Worth Township Need to Pay Attention

If you own a commercial property in Worth Township, Cook County, you recently received your 2025 reassessment notice on August 11, 2025. For many business owners, these notices brought news of higher assessments-and with them, the likelihood of higher property tax bills.

• The latest Worth Township commercial reassessment data and what it means for you.

• The step-by-step appeal process at both the Assessor’s Office and the Cook County Board of Review.

Understanding the Cook County Worth Township Commercial Appeal Process

Assessor’s Appeal Window (Closed September 23, 2025)

The Cook County Assessor’s Office mailed 2025 assessment notices on August 11, 2025. Property owners had a 43-day window to file an appeal directly with the Assessor, which closes on September 23, 2025.

Board of Review (BOR) Appeal Window (Upcoming)

Even after the Assessor’s window closes, you still have a second chance through the Cook County Board of Review.

• Pre-Filing: Commercial owners can pre-file appeals before official dates open.

• Filing Dates: The Board of Review will announce official opening/closing dates for Worth Township soon.

• Check Status: Monitor the Cook County Board of Review portal for updates.

How to File a Commercial Property Appeal

Documentation Requirements for Commercial Appeals

Commercial appeals are different from residential appeals. Instead of relying solely on comparable properties, the Cook County Assessor requires income and market data. Essential documents may include:

• Property Summary Sheet

• Rent Rolls (for apartments, industrial, or commercial properties)

• Income & Expense Statements

• Sales Questionnaires

• Vacancy Affidavits

Step-by-Step Appeal Process

1. Gather Evidence: Collect rent rolls, income/expense data, and vacancy details.

2. File Appeal with Assessor: Submit through the Assessor’s online portal before the September 23, 2025 deadline.

3. Prepare for BOR: Even if you filed with the Assessor, prepare for a potential Board of Review filing.

4. Consider Professional Help: Commercial appeals often require professional analysis to maximize savings.

Why These Assessment Changes Matter for Worth Township Business Owners

Imagine a motel assessed at $10 million in 2024. With a nearly 10% increase, the new assessed value becomes $11 million. That additional $1 million in assessed value translates directly into higher property taxes-potentially tens of thousands of dollars annually.

On the other hand, if you own a greenhouse or ancillary structure that stayed flat or dropped, you might argue your assessment is too high compared to the township median. That’s a strong case for appeal.
