Illinois Homestead Exemption: Cook County Homeowner, Senior and Freeze Rules
The Illinois homestead exemption in Cook County: the Homeowner exemption cuts EAV by $10,000, Senior by $8,000. Eligibility, renewal and how to check yours.
Quick answer
In Cook County, the Illinois homestead exemption is the Homeowner Exemption: it reduces a home's equalized assessed value by $10,000 if you own and occupy it as your principal residence. Senior, Senior Freeze and Persons with Disabilities exemptions are separate programs, each with its own eligibility and renewal rules.
What is the Illinois homestead exemption?
In Cook County the best-known homestead exemption is called the Homeowner Exemption. The Cook County Assessor's Office says most homeowners are eligible "if they own and occupy their property as their principal place of residence," and that it works by reducing the equalized assessed value (Cook County Assessor, Homeowner Exemption).
Illinois has several related exemptions, and Cook County lists them side by side: Homeowner, Senior, Senior Freeze, Persons with Disabilities, and others for veterans, longtime homeowners and home improvements. This article covers the first four. The Assessor's office is the source for every figure below, and the figures can change from year to year, so check the current page before you rely on one.
A homestead exemption in this sense is a tax matter. It is a different thing from the creditor-protection rules some states also call a homestead. The general article on the homestead exemption explains how the two meanings differ across states.
Definition
Homestead exemption (Cook County, Illinois) — A property tax break for a primary residence that lowers the home's equalized assessed value (EAV), the partial value of the property that is used to calculate the tax bill.
How does the Cook County Homeowner Exemption work?
It subtracts a fixed amount from your EAV before the tax rate is applied. The Assessor states: "The Homeowner Exemption reduces the Equalized Assessed Value (EAV) of a property by $10,000." (Cook County Assessor, Homeowner Exemption).
The $10,000 is not the amount your bill drops. Your savings are $10,000 multiplied by your local tax rate, and the Cook County Clerk determines that rate each year. Using the Assessor's own worked example, a home with a $100,000 estimated market value has a $10,000 assessed value at the 10 percent residential assessment level. After the 2024 state equalizer of 2.9237, the EAV is $29,237. Subtract the $10,000 exemption and the adjusted EAV is $19,237. At the page's example rate of .08 (the page says your rate could vary), the estimated bill is $1,538.96.
Run the same example without the exemption and the bill would be $29,237 times .08, or $2,338.96. The exemption in that illustration is worth $800. Your own rate, equalizer and value will differ.
Exemptions show up on your second installment tax bill, which the Assessor says is issued in the summer.
Cook County homestead-type exemptions compared
The table below summarizes four residential exemptions as described on the Cook County Assessor's pages. Dollar amounts and income limits are the ones shown on those pages when we fetched them and are tied to the tax years the pages mention.
| Exemption | Who it is for | Effect on the property | Renews automatically? |
|---|---|---|---|
| Homeowner | Owners who live in the home as their principal residence | Reduces EAV by $10,000 | Yes |
| Senior | Owner-occupants 65 or older (born in 1960 or prior, per the page) | Reduces EAV; the page's example uses $8,000 | Yes |
| Low-Income Senior Freeze | Seniors over 65 with total household income of $65,000 or less in calendar year 2024 | Freezes the EAV at a fixed amount | No, file every year |
| Persons with Disabilities | Persons with disabilities | Reduces EAV by $2,000 a year | Yes for last year's recipients; new applicants must apply |
Who qualifies for the Homeowner Exemption?
You qualify if you meet two tests on January 1 of the tax year. The Assessor lists them as: you either own the home or have a lease or contract that makes you responsible for the real estate taxes, and you occupy it as your principal place of residence on January 1 (the page names January 1, 2025 for the 2025 tax year).
A newly built home is the main timing exception. The exemption is prorated if you bought a new-construction home that was not ready to occupy until some time after January 1. Cooperative owners cannot use the normal online system and apply by a separate form sent to the Assessor.
Because the first test turns on who owes the property tax, the Assessor checks the deed. If you are listed on the deed recorded at the Cook County Clerk's Office, staff can verify it for you. If you are not on the recorded deed, you provide other proof of tax liability, such as an unrecorded deed, a contract for a deed, a trust agreement, a stock certificate or an occupancy agreement.
What are the Senior, Senior Freeze and disability exemptions?
They are separate programs that sit alongside the Homeowner Exemption, each with its own eligibility.
The Senior Exemption is for owner-occupants who are 65 or older. The Assessor's page says it reduces the equalized assessed value and renews automatically once applied. Its worked example uses $8,000 as the savings amount, again multiplied by your local tax rate.
The Low-Income Senior Freeze works differently. It is for seniors over 65 whose total household annual income was $65,000 or less in calendar year 2024, per the current page, and it holds the EAV at a fixed amount. The Assessor adds a caution: "This does not automatically freeze the amount of their tax bill, only the EAV remains at the fixed amount." (Cook County Assessor, Low-Income Senior Freeze Exemption). Tax rates can still change the bill. This is the one exemption in the group that does not renew automatically.
The Persons with Disabilities Exemption provides an annual $2,000 reduction in EAV. The Assessor's page says that, due to new state legislation, people who received it last year are renewed automatically going forward, while new applicants complete an application (Cook County Assessor, Persons with Disabilities Exemption).
How do you apply for the Homeowner Exemption in Cook County?
Check what is already on your property
Open your property details on the Assessor's site and review the Exemption History and Status section. If the Homeowner Exemption is already applied and renewing, you may have nothing to file.
Gather proof of identity and occupancy
The Assessor asks for one photo ID from its List A (for example an Illinois driver's license or ID card) whose name and address match the application, plus an occupancy affidavit that is built into the online application. If your ID address does not match the property, you provide documents from two other lists instead, such as a bank statement or utility bill showing occupancy.
Confirm your property tax liability
If you are on the recorded deed, the Assessor can verify that itself. Otherwise attach one of the accepted documents, such as a contract for a deed or a trust agreement.
File online or on paper
The Assessor offers an online application and a downloadable paper form. Paper forms go to 118 North Clark Street, Room 320, Chicago, IL 60602. Cooperative owners follow the separate co-op instructions on the same page.
Watch for the result and the bill
Online filers can log in to see application status, and the Assessor notifies you by email. The exemption then appears on the second installment bill.

What happens to the exemption when ownership changes?
The exemption follows the occupant and the January 1 test, not the property forever. The Assessor offers an Exemption Removal Waiver for owners who are no longer eligible, so a seller or a household that has moved out should not leave an old exemption in place.
The Assessor also has a page on erroneous exemptions, listed in its exemptions menu, which we did not fetch and so do not describe here. If you buy a home, do not assume the seller's exemptions carry over to you. You file for the years you qualify.
This is why a records search often shows exemption history on a property but cannot tell you whether a past exemption was correct. A search of the public record lists recorded deeds and liens. It is not title insurance and not legal advice. For the Cook County deed record itself, see the guide to Cook County deed search, the Cook County title search page, and the broader Illinois title search page. The pricing for those searches is Current Owner Search $49, Two Owner Search $79 and 30-Year Search $129.

Frequently asked questions
- How much is the Illinois homestead exemption in Cook County?
- The Cook County Assessor says the Homeowner Exemption reduces a property's equalized assessed value by $10,000. Your actual tax savings are that $10,000 multiplied by your local tax rate, which the Cook County Clerk sets, so the dollar amount on your bill varies by location.
- Does the Cook County homestead exemption renew automatically?
- The Homeowner Exemption and the Senior Exemption renew automatically each year once applied, per the Assessor. The Low-Income Senior Freeze does not and must be filed annually. Persons with Disabilities recipients from the prior year renew automatically, while new applicants must apply.
- Who qualifies for the Cook County Homeowner Exemption?
- Owners, or people whose lease or contract makes them responsible for the real estate taxes, who occupy the home as their principal residence on January 1 of the tax year. A newly built home that was not ready for occupancy on January 1 can get a prorated exemption.
- What is the Cook County senior freeze exemption?
- It freezes the equalized assessed value of a home for seniors over 65 whose total household income was $65,000 or less in calendar year 2024, per the current Assessor page. It does not freeze the tax bill itself, because tax rates can still change. It must be filed every year.
- Where can I see which exemptions are on my Cook County property?
- The Assessor says to check your property details and then review the Exemption History and Status section. Exemptions appear on the second installment tax bill, which is issued in the summer. Online filers can also log in to check an application's status.
- What if I never got the homestead exemption for a past year?
- The Assessor handles missed exemptions as Certificates of Error. Its pages describe this route for the current year after the normal filing period ends and for prior years such as 2023, 2022 and 2021, with processing that is longer than usual. Check the current page for which years are open.
- Is a homestead exemption the same as protection from creditors?
- No. In Cook County the exemptions described here lower the equalized assessed value used for property tax. Creditor protection for a home is a separate legal question that this article does not cover, since we could not retrieve the Illinois statute text. Ask an Illinois attorney about that.
- Do I need to file again after I buy a new home in Cook County?
- Do not assume the seller's exemption transfers. The Assessor ties the Homeowner Exemption to who owns or is responsible for the taxes and who occupies the home on January 1. Check your new property's exemption history and file if your home does not show the exemption.
