Data Overview and Key Metrics

Data analysis prepared by Cook County Tax Appeals using Cook County Assessor appeal outcome records for Elk Grove Township.

Township Appeal Results Overview

This report summarizes Cook County Assessor appeal outcomes for Elk Grove Township for the tax year 2025. Each record includes a property class, a proposed assessed value, a final assessed value, and an appeal outcome marked Change or No Change.

Township-level results matter because appeal outcomes and reductions can vary by location and property type. Cook County Tax Appeals reviews these trends to help Cook County property owners understand what typically happens after an appeal is filed.

Overall Appeal Success Rate

In this dataset, an appeal is counted as successful when the outcome is marked “Change.” That means the Assessor’s value or classification was adjusted in response to the appeal.

• 2,229 of 17,460 appeals received a Change

• That equals an overall success rate of 12.8%

A “No Change” outcome does not necessarily mean the property was fairly assessed. It often means the evidence submitted did not meet the Assessor’s standard, the comps did not support a reduction, or the file was missing key documentation. A careful review of value, comps, income (for larger properties), and property details can make a big difference in results.

Appeal Success Rate by Property Class

Success rates were not the same across property classes. Some classes saw relatively low change rates, while others were much more likely to receive a reduction.

Key takeaways from the class trend data

• High-volume classes can still have modest success rates. A large number of filings does not automatically mean a high change rate.

• Some smaller categories performed strongly. A few classes posted noticeably higher success rates than the township average.

• Results vary for real reasons. Different classes often require different evidence (sales comps vs. income support, property condition details, classification support).

Cook County Tax Appeals tracks these class-level patterns across Cook County townships to help property owners understand which approaches tend to perform best for their property type.

Assessed Value Changes Explained

On average, values moved down from $90,242 (proposed) to $85,149 (final).

That is an average decrease of about:

• $5,093 per appeal, or

• roughly a 5.6% reduction from proposed to final (average-to-average)

Why this matters

Your assessed value is a key input into your property tax bill. A lower assessed value can reduce the taxable value used in later steps of the tax calculation. Even when a reduction seems small, it can compound in impact depending on your property’s tax rate and exemptions.

What These Results Mean for Property Owners

If you own property in Elk Grove Township, this data suggests a few practical takeaways:

• Evidence quality matters. Strong comps, accurate property characteristics, and clear documentation improve the odds.

• Property class influences outcomes. Understanding how your class performs can help set expectations and shape your strategy.

• Appeal timing is critical. Cook County appeal windows are short, so being prepared before your filing period opens helps avoid last-minute mistakes.

FAQ: Elk Grove Township Cook County Property Tax Appeals

1) What does “Change” mean in a Cook County Assessor appeal?

“Change” means the Assessor adjusted something based on the appeal, most commonly the assessed value (and sometimes classification). In this report, “Change” is treated as a successful appeal outcome.

2) Can I appeal even if my taxes went up but my assessed value did not?

Yes. A tax bill can rise due to rate changes, levies, or shifts in the tax burden, even if your assessed value did not change. An assessment appeal focuses on whether the assessed value and classification are accurate.

3) What evidence typically helps the most in a Cook County property tax appeal?

For many residential properties, recent comparable sales and correct property details are key. For income-producing properties, income and expense information often matters. The best evidence depends on the property type and class.

4) Why do appeal success rates vary by property class?

Different classes are valued differently and may require different types of proof. Some classes also have more consistent data, while others vary widely by condition, income performance, or property-specific factors.

5) If I receive “No Change,” can I appeal again?

Often, yes. Many owners appeal first with the Assessor and may still have another opportunity through the Board of Review, depending on timing and eligibility.
