What is the Illinois homestead exemption and who qualifies?

The Illinois Homestead Exemption, also called the Homeowner Exemption, is a property tax benefit. It reduces the taxable value of your primary residence. By lowering your home’s equalized assessed value (EAV), this exemption can help reduce your property tax bill.

This exemption is often used by Cook County homeowners. It is one of the best ways to lower property taxes in Illinois.


How the Homestead Exemption Works

Property taxes in Illinois are calculated using the equalized assessed value (EAV) of your property.

The Homestead Exemption reduces the taxable value before the tax bill is calculated. When the taxable value is lower, the final property tax bill may also be lower.

The exact tax savings will depend on:

  • Your property’s assessed value

  • The exemption amount

  • Local tax rates set by taxing districts


Who Qualifies for the Illinois Homeowner Exemption?

To qualify for the Illinois Homestead Exemption in Cook County, you must meet several requirements.

1. You Must Own the Property

The property must be owned by the person applying for the exemption.


2. The Property Must Be Your Primary Residence

The home must be your principal place of residence. This means you live there most of the year.

Second homes, rental properties, and investment properties generally do not qualify.


3. You Must Occupy the Property

You must live in the property on January 1 of the tax year for which the exemption is being claimed.


Other Homestead-Related Exemptions in Illinois

In addition to the standard Homeowner Exemption, Illinois offers several related exemptions for qualifying homeowners.

Examples include:

  • Senior Citizen Homestead Exemption for homeowners age 65 or older

  • Senior Freeze Exemption that can freeze the assessed value for qualifying seniors

  • Disabled Persons Homestead Exemption for homeowners with disabilities

  • Veterans with Disabilities Exemption

These programs can further reduce property taxes for eligible residents.


How to Apply for the Homestead Exemption

Homeowners can apply through the Cook County Assessor’s Office.

In many cases, the exemption is applied automatically when the Assessor confirms that the property is owner-occupied. However, some homeowners may need to apply or verify their eligibility.

Information typically required includes:

  • Proof of ownership

  • Proof that the property is your primary residence

  • Identification or residency documents
