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

Other Homestead-Related Exemptions in Illinois

How to Apply for the Homestead Exemption
