Illinois has the second-highest effective property tax rate in the country at 2.07%. For Chicago homeowners, one of the simplest ways to lower your bill is a tool most people qualify for, but many overlook: the homeowners exemption.
This guide covers which property tax exemptions Chicago homeowners qualify for, how much they actually save, how to apply, and what to do if you missed past years.
Key Takeaways
There technically isn't a homestead exemption for the city of Chicago. It's a state-wide homestead exemption that gives additional tax relief to Cook County residents.
Illinois' homestead exemption for Cook County residents reduces the Equalized Assessed Value (EAV) by $10,000, saving most Chicago homeowners $600-$1,000+ per year, depending on their local tax rate.
You qualify if you own and occupy the property as your primary residence as of January 1 of the tax year.
The exemption auto-renews each year after your first approval.
If you missed applying, you can recover up to 3 years of savings through a Certificate of Error.
Stacking the homeowner exemption with a property tax appeal can significantly multiply your savings.
What Is the Chicago Homeowners Exemption?
The Illinois General Homestead Exemption (GHE), also called the homestead exemption, reduces the Equalized Assessed Value (EAV) of your primary residence by $10,000 in Cook County.
It's one of the most straightforward ways to lower your annual tax bill, and it's available to most owner-occupants in Chicago. For a broader look at how this fits into the statewide system, see our guide to homestead exemptions in Illinois.
To understand how it works, you need to know what EAV means. In Cook County, residential properties are assessed at 10% of their fair market value (FMV). That assessed value is then multiplied by the state equalization factor to produce the EAV. The EAV is the property value to which your local tax rate is applied when calculating your bill.
The 2025 Cook County equalization factor is 3.0300. So if your home has a fair market value of $350,000, the assessed value would be $35,000 (10%), and the EAV would be approximately $106,050 ($35,000 x 3.0300).
The $10,000 GHE is not $10,000 off your tax bill. It's $10,000 off the EAV, the taxable value used to calculate your bill. The actual dollar savings depend on your local tax rate, which varies by neighborhood and township across Chicago.
Eligible property types include single-family homes, townhomes, condominiums, co-ops, and apartment buildings up to 6 units. If you own and live in one of these as your primary residence, you likely qualify.
Unlike in some states, where exemptions are applied automatically, Chicago homeowners must apply for this exemption the first time. That extra step is part of why so many eligible properties go without it.
How Much You'll Actually Save on Your Tax Bill
The savings formula is straightforward:
Exemption Amount ($10,000) x Local Tax Rate = Annual Savings
Chicago tax rates typically fall between 6% and 10%, depending on your township and local taxing districts. That means the homeowners exemption saves most Chicago homeowners between $600 and $ 1,000 or more per year.
Here's a worked example using a representative Chicago home:
Line Item | Without Exemption | With Exemption |
|---|---|---|
Fair Market Value: | $350,000 | $350,000 |
Assessed Value (10%): | $35,000 | $35,000 |
EAV (x 3.0300 factor): | $106,050 | $106,050 |
Exemption Applied: | $0 | -$10,000 |
Taxable EAV: | $106,050 | $96,050 |
Tax Rate: | 8% | 8% |
Annual Tax Bill: | $8,484 | $7,684 |
Annual Savings: | — | $800 |
At a higher tax rate of 10%, the same exemption saves $1,000 per year. At 6%, it saves $600.
The multi-year impact is significant. Over 10 years, that single application could save you $8,000-$10,000 or more, all from filling out one form. And because the exemption auto-renews after your first approval, you don't need to reapply each year.
Unsure Which Exemptions You Qualify For?
Who Qualifies for the Chicago Homeowners Exemption
The eligibility requirements are clear-cut. You must meet all of the following:
Own the property: You must be the owner, or have a lease or contract that makes you responsible for property taxes.
Primary residence: The property must be your principal place of residence as of January 1 of the tax year.
Eligible property type: Single-family homes, townhomes, condominiums, co-ops, and apartment buildings up to 6 units all qualify.
If you moved into a newly constructed home after January 1, you may still qualify for a prorated exemption for the portion of the year you occupied the property.
Who does not qualify:
Owners of rental or investment properties where you do not live on-site (owner-occupants of 2-6 unit buildings do qualify for the unit they occupy)
Vacation or second-home owners
Commercial property owners
Once approved, the exemption renews each year automatically unless the property is sold or you move out. You only need to apply once, and the Cook County Assessor's Office handles renewal from that point forward.
How to Apply for the Homeowners Exemption in Chicago
Applying is a one-time process. Once approved, the exemption renews automatically in subsequent years.
Step 1: Gather your documentation
You'll need:
Photo ID matching the property address: An Illinois driver's license, City of Chicago ID, or Matricula Consular showing the property address.
If your ID doesn't match: A government-issued photo ID plus a 2025 occupancy document such as a bank statement, utility bill, or voter registration record.
Proof of property tax liability: A deed, trust agreement, or stock certificate (for co-ops).
Step 2: Submit your application
You can apply online through the Cook County Assessor's Office or by mail at 118 N Clark St, Room 320, Chicago, IL 60602.
Step 3: Check your status
After submitting, you can track your application through the Assessor's online portal.
Deadline: Applications are typically due in late April or early May. The exact date varies each year, so check the Cook County Assessor's website for the current deadline.
If you apply after the deadline, your application won't be denied outright. Instead, it will be processed as a Certificate of Error, which means you can still receive the exemption retroactively.
First-time applicants must file an application. Renewal is automatic in all subsequent years, so this is truly a one-time effort for ongoing savings.
Other Chicago Exemptions Worth Claiming
The GHE isn't the only way to reduce your tax bill. Cook County offers several additional exemptions that can stack together for even greater savings. You can review the full list of Cook County property tax exemptions on the Assessor's website, or explore our Cook County homestead exemption guide for a deeper breakdown.
Exemption | EAV Reduction | Who Qualifies | Renewal |
|---|---|---|---|
Homeowner | $10,000 | Any owner-occupant | Auto |
Senior (65+) | $8,000 | Homeowners age 65+ | Auto |
Senior Freeze (SCAFHE) | Freezes EAV | 65+, income $75,000 or less | Annual |
Disabled Person | $2,000 | Homeowners with a disability | Auto |
Disabled Veteran | 30-49%: $2,500; 50-69%: $5,000; 70%+: Exempt | VA-rated 30%+ disability; primary residence EAV must be under $250,000 | Annual (Except 100% permanently disabled veterans, who now auto-renew) |
Longtime Homeowner | $5,000-$10,000 | 10+ years ownership or 5 with assistance and income of $100,000 or less | Annual |
Returning Veteran | $5,000 | Returning from active duty | One-time (Only applies to the year of return) |
Stacking is where the real savings add up. A homeowner age 65 or older can combine the Homeowner exemption ($10,000) with the Senior exemption ($8,000) for a total of $18,000 off their EAV.
At an 8% tax rate, that's $1,440 in annual savings from exemptions alone.
According to Chicago Cityscape's analysis of tax year 2024 data, only 29.1% of Cook County properties (1,445,268 out of 4,961,030) have the homeowner exemption applied, which means many eligible homeowners are leaving money on the table. The Illinois Department of Revenue provides additional details on all available property tax relief programs statewide.
And exemptions are just one piece of the puzzle. Cook County homeowners have generated $2.8 billion in collective tax reductions through property tax appeals, demonstrating how much room there is to lower your bill beyond exemptions.
Missed the Deadline? How to Recover Past Savings
If you were eligible for the homeowners exemption in previous years but didn't receive it, you're not out of luck. The Certificate of Error process allows you to recover savings for up to 3 prior tax years.
A Certificate of Error is a correction filed with the Cook County Assessor's Office when a homeowner is eligible for an exemption but doesn't receive it. If approved, you will receive a refund or an adjusted tax bill for each year the exemption should have applied.
This situation is more common than you might think. It frequently happens when:
New homeowners didn't know they needed to apply (it's not always automatic from day one).
Homeowners changed names or transferred to a trust, and the exemption was dropped.
First-time buyers assumed the exemption carried over from the previous owner.
If you think you may have missed the exemption in prior years, recovering those savings is worth the effort. At an 8% tax rate, three missed years of the homeowners exemption could mean $2,400 in potential refunds.
At Ownwell, we retroactively apply for missed homestead exemptions for up to 3 years in Illinois. We handle all the paperwork, so you don't have to navigate the Certificate of Error process yourself.
How Much Are You Over Paying?
How Ownwell Can Help With Your Chicago Property Taxes
We handle both exemption applications and property tax appeals in Cook County, giving you two ways to lower your bill.
As mentioned, an exemption lowers your EAV. An appeal challenges whether your assessed value is accurate in the first place. Together, they compound your savings in a way that neither strategy achieves alone.
Our Cook County appeals operate on a 25% contingency basis, which means you only pay if we save you money. There's no upfront cost, and we handle the entire process from filing to hearings.
Here's how the combined strategy works in practice:
If a successful appeal reduces your assessed value by $3,000, Cook County's state equalizer multiplies that into a $9,000 reduction in EAV. Combined with the $10,000 homeowners exemption, you are reducing your total taxable EAV by $19,000. At an 8% tax rate, that translates to $1,520 in total annual savings.
Getting started takes less than a minute. Enter your address, and we'll provide a savings estimate in seconds.
We maintain an 88% success rate on appeals, with average annual savings of $774 for our customers. And we've earned a 4.7 rating across 3,000+ reviews.
Whether you need to claim an exemption for the first time, recover missed exemptions from past years, or challenge an inflated assessment, we manage the process from start to finish.
