llinois Property Tax Exemptions: How Homeowners Can Lower Their Tax Bill

Many Illinois homeowners don’t realize they may be overpaying on property taxes simply because they haven’t claimed the exemptions they qualify for. If you own and live in your home, you may be eligible for tax relief that can reduce your annual property tax bill — sometimes by thousands of dollars over time.

Here’s a simple breakdown of how Illinois property tax exemptions work and how to apply.

What Is an Illinois Property Tax Exemption?

A property tax exemption reduces the equalized assessed value (EAV) of your home. Since property taxes are calculated based on EAV, lowering it means lower taxes.

Exemptions are not automatic in every situation — especially after a purchase — so homeowners need to make sure they’re properly filed.

Most Common Illinois Property Tax Exemptions

🏠 General Homestead Exemption

This is the most common exemption for homeowners who live in their primary residence.

Available for owner-occupied homes
Reduces a portion of your home’s assessed value

Most homeowners qualify — but new buyers must apply after closing.

👵 Senior Citizens Homestead Exemption

Designed for homeowners 65 years or older.

Additional reduction beyond the General Homestead Exemption
Home must be the senior’s primary residence
Typically renews automatically once approved

Chicago & Cook County Homeowners: Important Note

In Cook County, exemptions do not always transfer automatically when a home is purchased. Many new homeowners receive a higher-than-expected tax bill simply because the exemption was never filed.

If you bought a home in the past year, it’s worth checking immediately.

Why This Matters More Than Ever

With property taxes rising across many Chicago neighborhoods and suburbs, exemptions are one of the easiest and safest ways to reduce housing costs — without refinancing or selling.

A quick application can mean years of savings.

Final Takeaway

If you own a home in Illinois and live in it, you should never assume your exemptions are already applied. Verify, file, and protect your wallet.
