Illinois Homestead Exemption: 2026 Rules, EAV Reductions & Property Tax Savings
Illinois homestead exemptions reduce the Equalized Assessed Value (EAV) used to calculate property taxes on a qualifying home. The General Homestead Exemption can reduce EAV by up to $10,000 in Cook County, $8,000 in counties contiguous to Cook County, and $6,000 in all other Illinois counties.
Additional relief may be available to homeowners age 65 or older, people with disabilities, returning veterans, veterans with service-connected disabilities, homeowners making qualifying improvements, and households affected by certain natural disasters.
What Does an Illinois Homestead Exemption Actually Save?
Illinois property-tax homestead exemptions normally reduce EAV, not your home’s market value and not your property-tax bill dollar-for-dollar. Your tax rate is then applied to the reduced taxable EAV.
“Tax Year 2026” and “Filing in 2026” Are Not Always the Same Thing
Illinois property taxes operate on a delayed cycle. This is especially important for the Senior Freeze because homeowners may see two different income figures while searching current 2026 filing information.
| What You Are Looking At | Relevant Rule | What It Means |
|---|---|---|
| Tax year 2025 | Taxes generally payable in 2026 | The Senior Freeze statutory income ceiling for tax year 2025 was $65,000. |
| Tax year 2026 | Taxes generally payable in 2027 | The statewide Senior Freeze household-income ceiling increases to $75,000. |
| Cook County filing during 2026 | Current portal is processing tax-year-2025 exemption claims | This is why Cook County’s current Senior Freeze materials can still display the older $65,000 figure tied to 2024 household income. |
Illinois General Homestead Exemption Amounts by County
The General Homestead Exemption is based on the increase in the property’s current EAV above its 1977 EAV, up to the applicable statutory maximum.
| Illinois Homestead Program | 2026 Benefit | Main Qualification | Typical Form / Action |
|---|---|---|---|
| General Homestead Exemption | Up to $10,000 Cook; $8,000 contiguous counties; $6,000 other counties in EAV. | Qualifying residential property used as the owner’s principal dwelling, or certain qualifying leasehold situations with responsibility for taxes. | Filing procedure varies by county. |
| Senior Citizens Homestead Exemption | Up to $8,000 EAV in Cook and counties contiguous to Cook; up to $5,000 elsewhere. | Generally age 65 or older, qualifying ownership/legal interest, principal residence and responsibility for property taxes. | PTAX-324 or county process; renewal rules vary. |
| Senior Assessment Freeze | Freezes qualifying EAV at a base amount rather than providing one fixed dollar deduction. | Age 65+, 2026 household income of $75,000 or less, plus other statutory requirements. | PTAX-340; file annually. |
| Persons with Disabilities | $2,000 annual EAV reduction. | Qualifying person with a disability occupying the primary residence and responsible for property taxes. | Initial PTAX-343; follow current county renewal instructions. |
| Returning Veterans | $5,000 EAV reduction. | Qualifying veteran returning from active duty in an armed conflict. | PTAX-341. |
| Veterans with Disabilities | $2,500, $5,000 or first $250,000 of EAV depending on service-connected disability rating. | Qualifying service-connected disability certified by the U.S. Department of Veterans Affairs. | PTAX-342 / county instructions. |
| Homestead Improvement Exemption | Up to $75,000 of added fair cash value, equivalent to up to $25,000 assessed value at 33⅓%, for up to four years. | Qualifying new improvement or rebuilding that increases homestead value. | PTAX-323 may be required. |
| Natural Disaster Homestead | EAV relief based on the statutory comparison with pre-disaster EAV. | Qualifying rebuilt residence following a widespread natural disaster. | PTAX-327; continued filing required. |

Illinois Senior Homestead Exemption vs Senior Freeze
These are separate benefits. A homeowner should not assume that receiving the ordinary Senior Citizens Homestead Exemption automatically enrolls the property in the Low-Income Senior Citizens Assessment Freeze.
Senior Citizens Homestead Exemption
Available to qualifying homeowners age 65 or older. The maximum EAV reduction is:
- $8,000 in Cook County.
- $8,000 in counties contiguous to Cook County.
- $5,000 in all other Illinois counties.
Filing and renewal procedures vary by county. PTAX-324 and PTAX-329 are among the state forms used for this program.
Low-Income Senior Assessment Freeze
The Senior Freeze does not simply subtract one standard number. It can hold the qualifying property’s EAV at its statutory base amount while the owner continues to qualify.
- Applicant must be at least 65.
- 2026 household-income ceiling: $75,000.
- Other ownership, residence and tax-liability requirements apply.
- Form PTAX-340 is filed annually.
| Tax Year | Maximum Senior Freeze Household Income | Taxes Generally Payable |
|---|---|---|
| 2025 | $65,000 | 2026 |
| 2026 | $75,000 | 2027 |
| 2027 | $77,000 | 2028 |
| 2028 and after | $79,000 | 2029 and after |
Illinois Homestead Exemptions for Veterans and People With Disabilities
Illinois has several programs with very different eligibility rules and exemption amounts. The veteran’s VA-certified service-connected disability percentage is especially important.
| Program / Rating | EAV or Assessment Benefit | Important Detail |
|---|---|---|
| Person with a qualifying disability | $2,000 EAV reduction | Initial application generally uses PTAX-343. Follow the current county’s renewal instructions. |
| Veteran disability: 30%–49% | $2,500 EAV reduction | Service-connected disability must be certified by the U.S. Department of Veterans Affairs. |
| Veteran disability: 50%–69% | $5,000 EAV reduction | Part of the Standard Homestead Exemption for Veterans with Disabilities. |
| Veteran disability: 70% or more | First $250,000 of qualifying EAV exempt | This can eliminate ordinary property tax on many qualifying residences where taxable EAV is within the exemption. |
| Returning veteran | $5,000 EAV reduction | Available for qualifying years connected to return from active duty in an armed conflict. PTAX-341 is used. |
| World War II veteran | Qualifying property exempt from taxation | Beginning with tax year 2024, qualifying WWII veterans receive the benefit regardless of disability percentage. |
| Specially adapted housing | Up to $100,000 reduction in assessed value | Separate program for certain qualifying specially adapted housing and federal assistance situations. |
Illinois Homestead Improvement Exemption
A qualifying home improvement does not always mean the entire added value becomes immediately taxable. Illinois provides temporary assessment relief for qualifying improvements and rebuilding.
Up to $75,000 added fair cash value
The exemption can cover up to $75,000 of fair cash value added by qualifying new improvements or qualifying rebuilding.
Up to $25,000 assessed value
Outside assessment systems with different classification rules, $75,000 of fair cash value corresponds to $25,000 at the statutory 33⅓% assessment level.
Four-year period
The Homestead Improvement Exemption generally continues for four years from completion and occupancy of the qualifying improvement or rebuilding.
Other Illinois Homestead and Property-Tax Relief Situations
Natural Disaster Homestead Exemption
Illinois provides a homestead exemption for qualifying residential structures rebuilt after a widespread natural disaster. The initial application generally uses PTAX-327 and is due by July 1 of the first taxable year after rebuilding, unless the county has established another filing date. Continued annual filing is required.
Cook County Longtime Homeowner Exemption
This is a specialized Cook County benefit for a small group of long-term homeowners who satisfy income, occupancy and significant-assessment-increase requirements. Cook County identifies potentially eligible properties and sends applications. It should not be confused with the ordinary Homeowner Exemption.
Municipality-Built Home Homestead Exemption
Illinois created a special exemption beginning with tax year 2024 for certain homes initially built by municipalities and later sold to private homeowners. Where the statute applies, the exemption can equal 50% of EAV during the first eight years of eligibility and 33% during years nine and ten. Eligibility is highly property-specific.
Residential accessibility improvements
Certain qualifying residential accessibility improvements—such as ramps, grab bars or widened doorways—may be protected from increasing the property’s assessed valuation for seven years. This is related property-tax relief but is not the same as the standard General Homestead Exemption.
Senior Citizens Real Estate Tax Deferral Program
This program is not an exemption. It allows qualifying seniors to defer all or part of property taxes and special assessments. Illinois pays the deferred amount and places a lien on the property; the amount plus applicable interest must later be repaid. Applications are handled through the county collector/treasurer rather than as an ordinary homestead exemption.
How to Apply for an Illinois Homestead Exemption
Illinois property taxes are administered locally. There is no single statewide portal that files every homestead exemption for every county, so your first task is identifying the correct county assessment office.
Find the county that assesses the property
Start with the county where the home is physically located. The local Chief County Assessment Office, supervisor of assessments or county assessor handles homestead exemption administration.
Find Illinois County Contact ↗Search the property record and confirm the PIN
Verify the property address, Property Index Number (PIN), owner information, EAV and current exemption history before filing.
Identify every exemption you may qualify for
Do not stop at the General Homestead Exemption if you are age 65 or older, have a qualifying disability, are a veteran, recently returned from active duty, rebuilt after a disaster or completed a qualifying improvement.
Use the current county application or state form
Common forms include PTAX-340 for the Senior Freeze, PTAX-341 for Returning Veterans, PTAX-342 for qualifying veterans with disabilities, PTAX-343 for Persons with Disabilities, PTAX-323 for improvements and PTAX-327 for natural disasters.
Gather evidence for that specific exemption
Depending on the program, the county may need proof of identity, principal residence, age, income, ownership or legal interest, disability certification, VA documentation or military-service records.
File by your county’s deadline
Do not assume another Illinois county’s deadline applies to you. Filing dates and local procedures can vary. The Senior Freeze requires an annual application even when another senior exemption may renew automatically.
Save proof of submission
Keep the confirmation number, uploaded documents, mailed copy or date-stamped receipt. It can be useful if the exemption does not later appear on the property record or bill.
Verify the exemption after processing
Check the county property record, assessment information and tax bill. If the exemption is missing, contact the assessment office promptly and ask about the county’s correction, late-application or omitted-exemption procedure.
Where Should You Go Next?
Choose the task you are trying to complete. The tool sends you to the relevant official Illinois or Cook County starting point.
Missed the May 15, 2026 Cook County Exemption Deadline?
Cook County’s current exemption pages say applications received after Friday, May 15, 2026 are processed as a Certificate of Error.
Normal application period has ended
For the current Cook County filing cycle, May 15, 2026 was the listed regular due date for major homeowner exemptions.
You may still have a correction route
Cook County says the Certificate of Error process can allow homeowners to request missing exemptions after the normal filing period and, where approved, receive the resulting savings through an adjusted bill or applicable refund process.
Missing Exemption vs High Assessment: They Are Different Problems
Your exemption is missing
Example: your property record should show a General Homestead or Senior Exemption but it does not.
Your assessed value is too high
Example: the assessor’s market value is excessive, property characteristics are wrong, or comparable properties are assessed less.
Looking for Protection From Creditors Instead of Property-Tax Savings?
Illinois also uses the term homestead exemption in its Code of Civil Procedure. That protection is separate from every property-tax exemption described above.
$50,000 per individual
Effective January 1, 2026, Illinois law provides an individual homestead estate of up to $50,000 of qualifying value.
Multiple owners
If two or more individuals own qualifying homestead property, each person’s exemption cannot exceed that person’s proportionate share of a combined $100,000.
Not an EAV reduction
This creditor-protection homestead estate concerns attachment, judgments, levies and judgment sales. It is not claimed through the county assessment office to lower annual property taxes.
Illinois Homestead Exemption Problems: What to Do Next
My exemption disappeared
Compare this year’s property record and bill with the prior year. Confirm ownership and principal-residence information has not changed.
Next: contact the Chief County Assessment Office and ask why the exemption was removed and what correction process applies.
My GHE is less than the maximum
The statute limits the General Homestead Exemption to the increase in current EAV above 1977 EAV, up to the county maximum.
Next: ask the assessment office to show the EAV figures used to calculate your exemption.
I turned 65 this year
The ordinary General Homestead Exemption does not automatically mean the Senior Citizens Homestead Exemption has been added.
Next: ask your county about its Senior Homestead filing procedure and also screen for the Senior Freeze.
My Senior Freeze tax bill still increased
The Senior Freeze generally freezes qualifying EAV—not tax rates or the entire bill.
Next: compare EAV, exemptions and tax rates on consecutive bills to identify which component changed.
I forgot to file the Senior Freeze
PTAX-340 is an annual filing. Missing the county deadline can jeopardize that year’s exemption.
Next: contact your county immediately and ask whether a late, supplemental or correction procedure remains available.
I moved during the year
Homestead eligibility depends on principal-residence, ownership or qualifying legal-interest facts for the tax year.
Next: tell the assessment office the acquisition and occupancy dates and ask which exemption, if any, can apply for that year.
I have a disability and veteran disability rating
Some disability-based programs cannot be claimed on the same property in the same tax year.
Next: compare the dollar benefit of the programs you qualify for before filing and follow the county’s veteran-exemption instructions.
My assessed value is wrong
An exemption application is not a substitute for an assessment appeal.
Next: obtain the property record card, verify characteristics and comparables, and check the local Board of Review appeal deadline.

Illinois Homestead Exemption FAQs
What is the Illinois homestead exemption?
For property-tax purposes, Illinois offers several homestead exemptions that reduce the Equalized Assessed Value of qualifying residential property. The most common is the General Homestead Exemption.
How much is the Illinois General Homestead Exemption in 2026?
The maximum EAV reduction is $10,000 in Cook County, $8,000 in counties contiguous to Cook County and $6,000 in all other Illinois counties. The actual General Homestead amount is limited by the statutory comparison with the property’s 1977 EAV.
Does a $10,000 homestead exemption save $10,000 in taxes?
No. It is an EAV reduction. For example, a $10,000 EAV reduction at a 7% aggregate tax rate represents approximately $700 of tax savings attributable to that reduction.
Who qualifies for the Illinois General Homestead Exemption?
It generally applies to qualifying residential property occupied as the principal dwelling by an owner or owners, and also to certain qualifying legal, equitable or leasehold interests where the statutory requirements, including responsibility for property taxes, are satisfied.
What is EAV in Illinois property taxes?
EAV means Equalized Assessed Value. It is the assessed value after applicable equalization. Homestead exemptions reduce taxable EAV, and the property’s aggregate tax rate is then applied in calculating the tax extension.
How much is the Illinois Senior Homestead Exemption?
The maximum Senior Citizens Homestead Exemption is $8,000 of EAV in Cook County and counties contiguous to Cook County and $5,000 in all other Illinois counties.
What is the Illinois Senior Freeze income limit for 2026?
For taxable year 2026, the statutory maximum household income is $75,000. Taxes for taxable year 2026 are generally payable in 2027.
Does the Illinois Senior Freeze freeze my tax bill?
No. It generally freezes the qualifying property’s EAV at its base amount. The tax bill can still change if tax rates rise or qualifying improvements increase taxable value.
How much is the Persons with Disabilities Homestead Exemption?
The Illinois Homestead Exemption for Persons with Disabilities provides a $2,000 annual reduction in the EAV of a qualifying primary residence.
How much is the Illinois disabled-veteran homestead exemption?
A qualifying service-connected disability of at least 30% but under 50% receives a $2,500 EAV reduction; 50% but under 70% receives $5,000; and a qualifying veteran rated 70% or more receives an exemption for the first $250,000 of EAV.
What is the Returning Veterans Homestead Exemption?
It provides a $5,000 reduction in EAV for a qualifying veteran returning from active duty in an armed conflict, subject to the statutory timing and residence requirements. Form PTAX-341 is used.
How does the Illinois Homestead Improvement Exemption work?
It can temporarily exempt up to $75,000 in added fair cash value from qualifying new improvements or rebuilding and generally lasts for four years from completion and occupancy.
Do Illinois homestead exemptions renew automatically?
It depends on the exemption and county. Some exemptions can renew automatically, while others require annual filing. The Senior Freeze requires annual PTAX-340 filing. Always follow the current instructions of the county administering your property.
Where do I apply for an Illinois homestead exemption?
Apply through the Chief County Assessment Office, supervisor of assessments or county assessor serving the county where the property is located. Illinois property taxes are administered locally rather than through one statewide filing portal.
What if my Cook County homestead exemption is missing in 2026?
Cook County says applications received after May 15, 2026 are processed as Certificates of Error. Check your property exemption history first, then use the current Cook County exemption or Certificate of Error procedure.
Is the Illinois creditor homestead exemption the same as the property-tax exemption?
No. Effective January 1, 2026, Illinois Code of Civil Procedure section 12-901 provides a separate homestead estate of up to $50,000 per individual, subject to a proportionate combined $100,000 limit where two or more individuals own the qualifying property. That is creditor protection, not an EAV property-tax exemption.
