Illinois property-tax relief • 2026 rules & practical guide
Illinois Homestead Exemption: Rules, Amounts, Eligibility & Property Tax Savings
An Illinois homestead exemption does not subtract a fixed dollar amount directly from your tax bill. Most Illinois homestead exemptions reduce the property’s equalized assessed value (EAV), and the applicable local tax rate is then applied to the lower taxable value.
For the regular General Homestead Exemption, the maximum EAV reduction is currently $10,000 in Cook County, $8,000 in counties contiguous to Cook County, and $6,000 in other Illinois counties. Seniors, persons with disabilities, veterans, homeowners making qualifying improvements and people rebuilding after certain natural disasters may qualify for additional or alternative relief.
Quick answer
How Does the Homestead Exemption Work in Illinois?
Illinois homestead exemptions are property-tax relief programs for qualifying residential property. The most common exemption is the General Homestead Exemption (GHE), which is generally associated with an owner-occupied principal residence.
A “$10,000 exemption” does not normally mean $10,000 is removed from the tax bill or market value. It means up to $10,000 can be removed from EAV under the General Homestead Exemption calculation in Cook County.
Avoid year confusion
Illinois Assessment Year vs. the Year You Pay the Tax Bill
Illinois property tax generally operates on a two-year cycle. Property is assessed in one year, while the resulting tax is generally billed and paid during the following year.
The assessor determines the applicable 2026 assessment and exemptions.
The resulting 2026 property taxes are generally paid the following year.
The statewide Senior Freeze income limit of $75,000 applies to taxable year 2026, payable in 2027. A bill actually being paid during calendar year 2026 normally relates to an earlier assessment year, so do not compare different tax years as if they were the same.
Most common exemption
Illinois General Homestead Exemption Rules
The General Homestead Exemption is established under 35 ILCS 200/15-175. It generally applies to residential property occupied as the owner’s principal dwelling place.
Who can qualify?
The property must qualify as homestead property and be occupied as the qualifying person’s principal dwelling.
The qualifying occupant generally must have an ownership interest or another legal/equitable interest allowed under the statute.
The qualifying person must be liable for payment of the real estate taxes under the applicable ownership or qualifying lease arrangement.
The law also includes certain leasehold interests involving a single-family residence when the statutory conditions are satisfied.
Maximum General Homestead Exemption by location
| Property location | Maximum EAV reduction | What it means |
|---|---|---|
| Cook County | $10,000 | Up to $10,000 may be removed from EAV under the statutory GHE calculation. |
| Counties contiguous to Cook County | $8,000 | The maximum General Homestead reduction is lower than Cook County’s maximum. |
| All other Illinois counties | $6,000 | This is the statewide maximum for counties outside the first two categories. |
The statutory GHE calculation is based on the increase in the current year’s EAV above the property’s 1977 EAV, subject to the applicable maximum. The maximum figures are therefore ceilings rather than a promise that every qualifying parcel will receive exactly that amount.
Translate EAV into dollars
How Much Does the Illinois Homestead Exemption Save?
The simplest way to understand the benefit is:
Your actual tax rate depends on the taxing districts serving the parcel, so two Illinois homeowners receiving the same exemption can save different dollar amounts.
If the applicable tax rate were 8%
Find the exemption/EAV information and the parcel’s composite tax rate on your county assessment or tax records. Do not use an Illinois statewide average when estimating a specific property’s savings.
Understand the math
Market Value, Assessed Value, EAV and Taxable Value Are Different
Many homeowners misunderstand the exemption because Illinois property taxation uses several different values.
Estimated fair cash value of the property.
The value used in the assessment process before applicable equalization and exemptions.
Equalized assessed value after applicable equalization.
A qualifying reduction used in determining taxable value.
An assessment appeal challenges the assessed value. A homestead exemption reduces qualifying taxable value under a specific exemption law. A homeowner may need to address both issues separately.
Age 65+
Illinois Senior Homestead Exemptions
Illinois has two senior programs that are often confused: the Senior Citizens Homestead Exemption and the Low-Income Senior Citizens Assessment Freeze Homestead Exemption.
Senior Citizens Homestead Exemption
- Applicant must generally be 65 or older.
- Residence and tax-liability requirements apply.
- There is no statewide income test described for the regular Senior Citizens Homestead Exemption.
- Maximum EAV reduction is $8,000 in Cook County and counties contiguous to Cook County.
- Maximum is $5,000 in all other counties.
- Local application and renewal practices can vary.
Low-Income Senior Assessment Freeze
- Applicant must generally be 65 or older.
- Household-income requirement applies.
- 2026 taxable-year limit: $75,000 or less.
- 2027 taxable-year limit: $77,000 or less.
- 2028 and later under the current law: $79,000 or less.
- Form PTAX-340 must be filed annually.
It generally freezes the qualifying property’s EAV at the applicable base amount. The bill can still increase because tax rates can change or because qualifying additions/improvements affect the assessment.
What does “household income” mean?
For the Senior Freeze, Illinois law looks at the combined income of members of the household under the statutory definition, generally for the calendar year preceding the taxable year. Do not assume the test is based only on the homeowner’s federal taxable income.
Use IDOR’s current relief page for income limits and contact your county assessment office for the local PTAX-340 deadline.
Different from an exemption
Senior Citizens Real Estate Tax Deferral Is Not a Homestead Exemption
Illinois also offers a Senior Citizens Real Estate Tax Deferral Program. It should not be confused with an exemption.
Homestead exemption
Reduces qualifying taxable value and therefore can reduce the property-tax calculation.
Senior tax deferral
Allows eligible seniors to postpone qualifying taxes. The State effectively advances the deferred amount and a lien secures repayment.
IDOR explains that deferred amounts, applicable interest and lien fees eventually must be repaid under the Senior Citizens Real Estate Tax Deferral Act. Applications use Forms IL-1017 and IL-1018 and are handled through the local County Treasurer/Collector.
It is fundamentally different from a homestead exemption because deferred property taxes become an obligation secured against the property.
Persons with disabilities
Illinois Homestead Exemption for Persons With Disabilities
The Homestead Exemption for Persons with Disabilities provides an annual $2,000 reduction in EAV for a qualifying primary residence.
Core requirements
- The residence must be the qualifying person’s primary residence.
- The person must be liable for property taxes.
- The applicant generally must be owner of record or have a qualifying legal/equitable interest evidenced by a written instrument.
- Special rules apply to qualifying leasehold interests.
- Proof of disability must accompany the initial application.
For a single tax year, the same property cannot receive the Homestead Exemption for Persons with Disabilities together with either the Standard Homestead Exemption for Veterans with Disabilities or the specially adapted housing veterans exemption.
Military-related relief
Illinois Homestead Exemptions for Veterans
Illinois has several different veteran-related property-tax programs. They are not interchangeable.
Standard Homestead Exemption for Veterans With Disabilities
| VA service-connected disability | Current EAV treatment |
|---|---|
| At least 30% but less than 50% | $2,500 EAV reduction |
| At least 50% but less than 70% | $5,000 EAV reduction |
| 70% or more | First $250,000 of residential EAV exempt |
The percentage must be a service-connected disability as certified by the U.S. Department of Veterans Affairs. Ownership/leasehold, primary-residence and property-tax liability rules also apply.
For tax years beginning with 2024, IDOR states that property qualifying under this provision is exempt from taxation if the veteran was a member of the U.S. Armed Forces during World War II, regardless of disability level, subject to the statutory exemption requirements.
Surviving spouses
Illinois provides continuation or transfer rules for certain un-remarried surviving spouses. IDOR also notes special eligibility for qualifying surviving spouses of veterans killed in the line of duty and, beginning with tax year 2023, certain surviving spouses whose veteran’s death was service-connected and who receive qualifying VA dependency and indemnity compensation.
Returning Veterans’ Homestead Exemption
The exemption applies when a qualifying veteran returns from active duty in an armed conflict involving the U.S. armed forces. A veteran may become eligible again after another qualifying period of active duty and return.
Specially Adapted Housing Exemption
A separate exemption can provide up to a $100,000 reduction in assessed value for certain specially adapted housing owned and used by a qualifying veteran with a disability when the statutory federal-assistance/adaptation requirements are satisfied.
Because the correct program depends heavily on disability certification, military service, surviving-spouse status and the property itself, start with your Chief County Assessment Office and, where appropriate, your local Veteran Service Officer.
Home upgrades
Illinois Homestead Improvement Exemption
Improving a home can increase its assessed value. Illinois’ Homestead Improvement Exemption temporarily protects a qualifying portion of the added value from taxation.
The exemption can apply to qualifying new improvements such as remodeling or adding a room and to qualifying rebuilding after a catastrophic event. It generally continues for four years from the date the improvement or rebuilding is completed and occupied.
IDOR states that the Homestead Improvement Exemption may be granted automatically or the Chief County Assessment Office may require Form PTAX-323. Cook County has a different application procedure involving the County Assessor.
Often overlooked relief
Accessibility Improvements Can Receive Separate Assessment Protection
Illinois’ property-tax system also provides protection for qualifying residential accessibility improvements. IDOR’s current property-tax publication explains that qualifying accessibility improvements will not increase assessed valuation for seven years after completion.
It is not the same as the $2,000 Persons with Disabilities Homestead Exemption. A qualifying homeowner can have questions about both disability-based homestead relief and treatment of accessibility improvements.
Rebuilt homes
Illinois Natural Disaster Homestead Exemption
Illinois has a Natural Disaster Homestead Exemption for qualifying homestead property where a residential structure is rebuilt following a qualifying widespread natural disaster.
A widespread natural disaster damages or destroys the residence.
The residential structure is rebuilt and satisfies statutory conditions.
Use Form PTAX-327 with the Chief County Assessment Office.
IDOR states PTAX-327 must be filed each year to continue the exemption.
The initial Form PTAX-327 must generally be filed no later than July 1 of the first taxable year after the residential structure is rebuilt, or by another filing date established by the county.
Do not assume any storm, fire or casualty automatically creates eligibility. Confirm whether the event and rebuilding meet the statutory Natural Disaster Homestead Exemption requirements with the county assessment office.
Cook County only
Illinois Long-Time Occupant Homestead Exemption
The Long-Time Occupant Homestead Exemption is a special Cook County-only program. It should not be presented as a statewide exemption available in every Illinois county.
Under IDOR’s current guidance, qualifying households with income of $75,000 or less have EAV growth limited to 7% annually for purposes of the exemption calculation, while qualifying households above $75,000 through $100,000 use a 10% limit.
IDOR explains that the Long-Time Occupant Homestead Exemption has restrictions involving the General Homestead Exemption and Senior Freeze. Cook County homeowners should have the Assessor determine the proper treatment rather than attempting to add the exemptions together themselves.
Application workflow
How to Apply for a Homestead Exemption in Illinois
Illinois homestead exemptions are administered locally. The Illinois Department of Revenue publishes statewide rules and forms, but IDOR does not administer your individual property-tax exemption.
-
1
Identify your county assessment office
Look for the Chief County Assessment Office, Supervisor of Assessments or County Assessor responsible for your property.
-
2
Find your Property Index Number
The PIN—also called a parcel number or permanent index number in some locations—normally appears on the property-tax bill or assessment notice.
-
3
Check your current exemption history
Before filing a duplicate application, determine which exemptions are already applied to the parcel.
-
4
Select the correct exemption
General, Senior, Senior Freeze, disability, veteran, improvement and disaster exemptions have different requirements.
-
5
Use the county’s current application process
Some counties offer online applications; others use state PTAX forms or locally adapted workflows.
-
6
Attach required proof
Depending on the exemption, this may involve proof of ownership/interest, occupancy, age, household income, disability certification, veteran documentation or rebuilding information.
-
7
Submit before your county deadline
Do not assume every Illinois county has the same filing date. State law and local administration create different deadlines for different programs.
-
8
Save confirmation
Keep the submitted form, confirmation number, supporting records and the date filed.
-
9
Verify the exemption after processing
Check the assessment/exemption record and later tax bill. Filing an application does not prove it was approved.

Prepare before applying
Documents You May Need for an Illinois Homestead Exemption
Requirements vary by exemption and county, but having the following information ready can prevent unnecessary delays.
The list above is a preparation checklist, not a substitute for the document list on the current county application.
Troubleshooting
Illinois Homestead Exemption Missing From Your Property Tax Record?
- Check the correct tax year. Remember that an Illinois property tax paid this year generally relates to the prior assessment year.
- Confirm the correct PIN. Do not accidentally review a neighboring parcel, condo parking PIN or another related parcel.
- Check whether the exemption appears in county property details. Some counties display exemption history separately from the tax-bill PDF.
- Confirm the application was approved. A submitted application is not the same as an approved exemption.
- Check renewal requirements. The Senior Freeze and disability programs can require recurring verification even when another exemption does not.
- Check ownership and occupancy dates. A recent purchase or move can affect which taxable year first qualifies.
- Contact the Chief County Assessment Office. The assessment office—not IDOR—is generally the first place to resolve an individual exemption problem.
- Ask whether a correction procedure is available. County procedures differ when an otherwise eligible exemption was omitted from a prior assessment.
IDOR’s current Illinois Property Tax System guidance warns that erroneous homestead exemptions can lead to recovery of unpaid property taxes. Cook County also has statutory lien procedures for certain erroneous exemptions.
After buying a home
What New Illinois Homeowners Should Do After Closing
Do not assume an exemption shown on the seller’s old tax bill automatically establishes your future eligibility.
Use the deed, tax bill or county parcel-search system.
Check that the county’s property information reflects the transaction.
Determine which exemptions belonged to the prior owner.
Occupancy and ownership timing can determine the first assessment year for relief.
Use your own county’s exemption process.
Confirm the exemption actually appears after assessment processing.
Cook County differences
Cook County Homestead Exemption Rules Are Not Identical to the Rest of Illinois
State law establishes the exemption framework, but Cook County has several practical differences homeowners should recognize.
Cook has the highest General Homestead Exemption maximum EAV reduction.
The Long-Time Occupant Homestead Exemption is a Cook County-only program.
Applications, exemption status and missing-exemption correction procedures are handled through the Cook County Assessor.
Do not use a prior year’s Cook County application date for a current filing.
The Cook County Assessor currently states that exemption applications submitted after May 15, 2026 are processed through its Certificate of Error process for the applicable cycle. This is a Cook County administrative deadline/process, not a universal deadline for all 102 Illinois counties.
When an exemption is not enough
Homestead Exemption vs. Property Assessment Appeal
A homeowner can correctly receive every available exemption and still believe the underlying assessment is too high.
Wrong or missing exemption
Contact the county assessment office about eligibility, exemption status, application or correction procedures.
Assessment appears too high
Discuss the property record with the assessor and follow the county Board of Review assessment-appeal process within the applicable deadline.
IDOR explains that an assessment appeal concerns the property’s assessment—not the tax rate itself. Once the tax bill arrives, it is generally too late to begin an assessment appeal for that assessment year.
Illinois Property Assessment Appeal GuideWho actually handles what?
Which Illinois Property Tax Office Should You Contact?
Exemption applications, parcel assessment information and many assessment questions.
Formal local assessment appeals and county-specific deadlines.
Billing, payment, due dates and senior tax-deferral administration.
State property-tax laws, statewide publications, PTAX guidance and forms.
Illinois property taxes are locally administered. Individual parcel records, bills and exemptions are generally maintained by local officials rather than in a single statewide homeowner account.
Avoid costly confusion
Common Illinois Homestead Exemption Mistakes

The Freeze is income-tested and works differently.
Tax rates and improvements can still change the amount due.
A prior owner’s qualification does not establish the buyer’s eligibility.
Individual homestead exemptions are locally administered.
Programs such as the Senior Freeze and disability verification can require recurring filings.
Several disability/veteran and Cook County programs have specific combination restrictions.
Assessment-appeal deadlines often occur well before the bill is issued.
Frequently asked questions
Illinois Homestead Exemption FAQs
What is the homestead exemption in Illinois?
Illinois has several homestead property-tax exemptions. The most common is the General Homestead Exemption for qualifying principal residences. Other programs are available for seniors, qualifying low-income seniors, persons with disabilities, veterans, qualifying home improvements and certain rebuilt homes after natural disasters.
How much is the Illinois General Homestead Exemption?
The current maximum General Homestead Exemption reduction is $10,000 of EAV in Cook County, $8,000 in counties contiguous to Cook County and $6,000 in all other Illinois counties. The actual exemption can be lower because the statutory calculation is based on the increase in EAV above the property’s 1977 EAV.
Does a $10,000 Illinois homestead exemption save $10,000 in taxes?
No. The exemption reduces equalized assessed value rather than subtracting $10,000 directly from the tax bill. Approximate savings depend on the exemption amount and the parcel’s applicable property-tax rate.
How do I calculate Illinois homestead exemption savings?
A simplified estimate is the exemption’s EAV reduction multiplied by the property’s composite tax rate. For example, a full $10,000 EAV reduction at an illustrative 8% tax rate would correspond to roughly $800 of tax reduction. Actual tax rates and exemption calculations vary by parcel.
Do I apply for an Illinois homestead exemption through the state?
Generally no. Illinois property taxes and individual homestead exemptions are administered locally. Contact the Chief County Assessment Office, Supervisor of Assessments or County Assessor responsible for the property.
What is the Illinois Senior Citizens Homestead Exemption?
It is an annual exemption for qualifying residents age 65 or older who meet the applicable residence, ownership or legal-interest and property-tax liability requirements. The maximum EAV reduction is $8,000 in Cook County and counties contiguous to Cook County and $5,000 in other counties.
What is the income limit for the Illinois Senior Freeze in 2026?
For taxable year 2026, payable in 2027, the current statewide household-income limit is $75,000 or less. Under current Illinois law, it is $77,000 for taxable year 2027 and $79,000 for taxable year 2028 and later.
Does the Illinois Senior Freeze freeze my property-tax bill?
No. It generally freezes the qualifying property’s EAV at the applicable base amount. The actual tax bill can still change if tax rates change or qualifying improvements are added.
Does the Illinois Senior Freeze have to be renewed?
Yes. Illinois Department of Revenue guidance states that applicants must file Form PTAX-340 annually with the Chief County Assessment Office.
How much is the Illinois disability homestead exemption?
The Homestead Exemption for Persons with Disabilities provides an annual $2,000 reduction in EAV for a qualifying primary residence. The initial application is PTAX-343 and annual eligibility is generally verified with PTAX-343-R.
How much is the Illinois disabled veterans homestead exemption?
Under the Standard Homestead Exemption for Veterans with Disabilities, a service-connected disability of at least 30% but less than 50% provides a $2,500 EAV reduction, at least 50% but less than 70% provides $5,000, and 70% or more exempts the first $250,000 of residential EAV, subject to the program’s other requirements.
What is the Illinois Returning Veterans’ Homestead Exemption?
It provides a $5,000 EAV reduction on the principal residence of a qualifying veteran returning from active duty in an armed conflict. It generally applies for the tax year of return and the following tax year. Form PTAX-341 is filed with the Chief County Assessment Office.
Does Illinois have a homestead exemption for home improvements?
Yes. The Homestead Improvement Exemption can protect up to $75,000 of added fair cash value, equivalent to up to $25,000 in assessed value under the statewide one-third assessment relationship, for up to four years on qualifying improvements or rebuilding.
Will adding an accessibility ramp increase my Illinois property assessment?
Qualifying residential accessibility improvements can receive separate assessment protection. Current IDOR guidance states that qualifying accessibility improvements do not increase the assessed valuation for seven years after completion.
Does Illinois have a natural disaster homestead exemption?
Yes. Qualifying rebuilt homestead property following a widespread natural disaster can receive relief under the Natural Disaster Homestead Exemption. The initial PTAX-327 generally must be filed by July 1 of the first taxable year after rebuilding or by the filing date established by the county, and annual filing is required to continue the exemption.
Is the Long-Time Occupant Homestead Exemption available everywhere in Illinois?
No. Illinois Department of Revenue guidance identifies the Long-Time Occupant Homestead Exemption as a Cook County-only program.
Can I receive multiple Illinois homestead exemptions?
Some exemptions can apply alongside other relief, while others have specific combination restrictions. For example, the Persons with Disabilities exemption cannot be received in the same tax year as certain veterans-with-disabilities exemptions, and Cook County’s Long-Time Occupant exemption has separate combination rules.
Where do I find my Illinois Property Index Number?
Your PIN, parcel number or permanent index number is normally shown on the property-tax bill or assessment notice. Your county assessor or assessment office can also help identify the parcel.
What should I do if my Illinois homestead exemption is missing?
First confirm the parcel number and correct tax year, then review your county exemption record. If the exemption is missing, contact the local assessment office and ask whether the application is pending, was denied, requires renewal or can be corrected through the county’s missing-exemption procedure.
Is an Illinois homestead exemption the same as appealing my property assessment?
No. A homestead exemption provides statutory property-tax relief to a qualifying property. An assessment appeal challenges the assessed value itself. The processes have different rules and deadlines.
