How much does the Illinois homestead exemption save?

The General Homestead Exemption reduces your equalized assessed value by up to $6,000. At a typical Illinois suburban tax rate of 8–10%, this saves approximately $480–$600 per year. Additional exemptions for seniors, veterans, and persons with disabilities can stack on top for greater savings.

Do I need to apply for the homestead exemption every year in Illinois?

For the General Homestead Exemption, most Illinois counties apply it automatically once established and renew it as long as you remain the owner-occupant. However, the Senior Freeze Exemption must typically be renewed annually. Check with your specific county assessor for renewal requirements.

When should a new Illinois homeowner apply for the homestead exemption?

Apply as soon as possible after closing. Most counties have spring or early summer deadlines for exemptions to take effect on the current year's tax bill. Missing the deadline means the exemption won't apply until the following tax year. Check your county assessor's website for the exact deadline.

Does the homestead exemption transfer to the new owner when a home is sold in Illinois?

The General Homestead Exemption can transfer if the new owner establishes primary residency and applies. However, specialized exemptions like the Senior Freeze do not transfer — they are removed when ownership changes. New buyers should verify their exemption status and apply for any they qualify for promptly after closing.

Illinois Homestead Exemption Guide: How to Lower Your Property Tax Bill

The Illinois homestead exemption is one of the most straightforward ways to reduce your property tax bill — and one of the most commonly missed by new homeowners. If you’ve recently purchased a home in Illinois and haven’t applied, you may be leaving hundreds of dollars on the table every year. Here’s everything you need to know.

What Is the Homestead Exemption?

The Illinois homestead exemption reduces the equalized assessed value (EAV) of your primary residence before your tax rate is applied — effectively lowering your tax bill. It is available to homeowners who occupy their home as their principal place of residence as of January 1 of the tax year.

Renters, investors, and owners of vacation or secondary properties are not eligible. The exemption applies to your primary home only.

Types of Illinois Homestead Exemptions

General Homestead Exemption

The General Homestead Exemption reduces your EAV by up to $6,000 in Cook County and up to $6,000 in most collar counties (amounts may vary slightly by county). On a typical Illinois suburban tax rate of 8–10%, a $6,000 EAV reduction saves approximately $480–$600 per year.

In most Illinois counties, this exemption is applied automatically once you establish primary residency. In Cook County, you typically need to apply once — after that it renews automatically as long as you remain the owner-occupant.

Homestead Improvement Exemption

If you make improvements to your home — an addition, renovation, or finished basement — the Homestead Improvement Exemption limits the increase in your assessed value from those improvements for up to 4 years. The exemption caps the assessment increase at $75,000 of added value, preventing a large renovation from immediately spiking your tax bill.

Senior Citizens Homestead Exemption

Homeowners 65 and older who occupy their home as a primary residence qualify for an additional $5,000 EAV reduction (in Cook County; amounts vary in collar counties). Combined with the General Homestead Exemption, this can reduce EAV by $11,000 or more.

Senior Citizens Assessment Freeze Exemption

Also called the “Senior Freeze,” this exemption locks in the EAV of your home at a base year level for qualifying seniors — preventing future assessment increases from raising your tax bill. Income limits apply (typically $65,000 or less in combined household income). This must be applied for annually in most counties.

Persons with Disabilities Exemption

Homeowners with qualifying disabilities receive an EAV reduction of up to $2,000. Documentation of disability status is required.

Veterans and Disabled Veterans Exemptions

Illinois offers multiple veterans-specific exemptions:

Veterans with Disabilities Exemption: EAV reductions ranging from $2,500 to full exemption depending on disability rating percentage
Returning Veterans Exemption: A one-time $5,000 EAV reduction for veterans returning from active duty in an armed conflict
Standard Homestead Exemption for Veterans with Disabilities: Provides significant relief for veterans with service-connected disabilities rated at 30% or higher

How to Apply in Illinois

The application process varies by county but is generally straightforward:

Cook County: Apply online through the Cook County Assessor’s website (cookcountyassessor.com) or in person at an assessor’s office. First-time applicants must submit proof of ownership and residency (deed, driver’s license, utility bill).
Will County: Apply through the Will County Supervisor of Assessments. The General Homestead Exemption is typically applied automatically for owner-occupants, but verify your account shows the exemption on your tax bill.
Other collar counties: Contact your county assessor or supervisor of assessments directly. Most have online portals and streamlined first-time application processes.

Timing matters: Applications for exemptions affecting the current tax year are typically due in the spring or early summer. Missing the deadline means waiting until next year. Check with your county assessor for the specific deadline.

What New Buyers Should Do Immediately After Closing

If you’ve recently purchased a home in Illinois, take these steps promptly:

Look up your property on your county assessor’s website and verify the homestead exemption is applied
If it’s not listed, file for the General Homestead Exemption immediately
Check whether the previous owner was receiving a Senior Freeze or other specialized exemption — these do not automatically transfer to new owners and will be removed, potentially causing your first tax bill to be higher than expected
If you’re 65+, a veteran, or have a disability, apply for any additional exemptions you qualify for
