Why You Should Consider a Property Tax Appeal Lawyer
If you’re a homeowner or commercial property owner in Cook County, you may be paying more in property taxes than necessary. At Park & Longstreet, P.C., our experienced property tax appeal lawyer in Chicago, IL, helps clients challenge inaccurate assessments and reduce their tax burdens. Understanding how assessments work—and when to appeal—can lead to significant savings.
How Property Tax Assessments Work in Chicago, IL
Property taxes in Chicago, IL, are based on the assessed value of your property, which is determined by the Cook County Assessor’s Office. This value is meant to reflect the fair market value of your property, but the process is far from perfect.
Assessments are calculated using mass appraisal techniques, which often rely on outdated or generalized data. These methods can overlook unique property characteristics, recent market changes, or even clerical errors. As a result, many property owners end up with inflated assessments and higher tax bills.
Common Reasons to Appeal Your Property Tax Assessment
Many property owners in Chicago, IL, are surprised to learn that their tax assessments may be based on outdated, inaccurate, or unfair information—making an appeal with a property tax lawyer not only possible but often necessary.
1. Incorrect Property Details
One of the most common reasons for over-assessment is inaccurate property data. If your assessment lists the wrong square footage, number of bedrooms, or even the wrong lot size, your property may be valued higher than it should be.
2. Unfair Comparables
Assessors use comparable properties (or “comps”) to determine value. If your property is being compared to newer, renovated, or more desirable homes or buildings, your assessment may be unfairly inflated.
3. Market Value Discrepancies
If the real estate market in your area has declined or your property has unique issues (like structural damage or location disadvantages), your assessed value may not reflect its true market value.
4. Recent Purchase Price Is Lower
If you recently purchased your property for significantly less than the assessed value, that’s a strong indicator that your assessment is too high. This is especially relevant for commercial properties, where market fluctuations can be more volatile.
5. Commercial Property Income Loss
For commercial property owners, a drop in rental income or high vacancy rates can justify a lower valuation. A property tax lawyer can help present this financial data effectively during the appeal process.
What to Look for on Your Property Tax Assessment
Before filing an appeal, it’s important to carefully review your assessment notice.
Here are key elements to examine:
- Assessed Value vs. Market Value: Compare the assessed value to recent sales of similar properties in your area.
- Property Characteristics: Verify that the listed features (square footage, number of units, lot size) are accurate.
- Comparable Properties: Research which properties were used as comps and whether they are truly similar to yours.
- Exemptions: Ensure that all applicable exemptions (e.g., homeowner, senior, or disabled) have been applied.
If anything seems off, it may be time to consult a property tax appeal lawyer in Chicago, IL.

Key Steps in the Appeal Process
Understanding the step-by-step process of a property tax appeal can help you stay organized, meet critical deadlines, and improve your chances of success.
1. Receive Your Assessment Notice: This typically arrives by mail and includes your new assessed value and appeal deadline.
2. Review and Research: Compare your assessment to similar properties and check for errors.
3. File Your Appeal: Submit your appeal to the Assessor’s Office or Board of Review, depending on the timing.
4. Attend a Hearing (if needed): You may be required to present your case in person or virtually.
5. Await the Decision: If successful, your new assessment will be reflected in your next tax bill.
Missing a deadline means waiting another year to appeal, so it’s important to act quickly.
