Illinois Homestead Exemptions

Last reviewed: May 16, 2026. Confirm the current form, tax year, and filing deadline with the official county office before applying.

What an Illinois homestead exemption actually does

A homestead exemption usually does not create a cash payment. It reduces the Equalized Assessed Value, often called EAV, of a qualifying home. Your tax bill is then calculated using that lower taxable value.

The Illinois Department of Revenue explains the main homestead exemptions on its official property tax relief page. That page is the best statewide source for exemption types, legal names, and state limits. Your county page is the best source for filing details.

An exemption is not the same thing as an appeal. If the county valued your home too high, you may need an assessment appeal. If the county forgot an exemption, you may need an exemption correction or prior-year process.

Main Illinois homestead exemptions at a glance

General Homestead Exemption

The General Homestead Exemption is the basic Illinois owner-occupied home exemption. It applies to residential property occupied by the owner as the principal dwelling place. State rules also include certain leasehold interests where the person has a qualifying interest and is liable for the taxes.

The Illinois Department of Revenue says the exemption is based on the increase in EAV above the property’s 1977 EAV, up to a maximum of $10,000 in Cook County, $8,000 in counties contiguous to Cook County, and $6,000 in all other counties.

That limit is an EAV reduction, not a promised bill reduction. The final tax effect depends on your local tax rates and the rest of your tax bill.

Check whether the exemption is already on your property record. Cook County homeowners can start with the Cook County Assessor exemptions page. DuPage County homeowners can start with the DuPage County exemptions page. Other counties usually use the county assessment office, supervisor of assessments, or township assessor.

Senior Citizens Homestead Exemption

The Senior Citizens Homestead Exemption is separate from the basic homeowner exemption. It is generally for a person age 65 or older who occupies the property as a residence, is liable for the real estate taxes, and has the required ownership, legal, equitable, or qualifying leasehold interest.

The state lists the maximum EAV reduction as $8,000 in Cook County and counties contiguous to Cook County, and $5,000 in all other counties.

There is no statewide income limit for the regular Senior Citizens Homestead Exemption. Do not confuse it with the Senior Freeze, which does have an income rule.

Filing rules vary. Some counties require an initial application. Some require a renewal or status form in certain cases. Cook County’s current senior exemption page says most eligible senior homeowners for Tax Year 2025 are people born in 1960 or earlier who own and occupy the property as their principal residence, and that the exemption automatically renews once applied.

The Senior Freeze is not a full bill freeze

The Low-Income Senior Citizens Assessment Freeze Homestead Exemption is often called the Senior Freeze. It freezes the EAV base for a qualifying home. It does not freeze the tax rate, tax district levies, or every possible increase in the tax bill.

The state says the bill may still increase if tax rates rise or if improvements are added that increase value. This point matters for seniors who are trying to understand why a bill can still go up after the exemption is approved.

To qualify, a person must be at least 65 and meet income and other rules. The Illinois Department of Revenue’s current property tax relief page lists Senior Freeze household income limits as $75,000 or less for taxable year 2026, $77,000 or less for taxable year 2027, and $79,000 or less for taxable year 2028 and after.

Counties may still be processing a prior tax year under a different form. For example, Cook County’s Tax Year 2025 Senior Freeze page used 2024 household income and listed a $65,000 limit. Always check the tax year printed on your county application.

The Senior Freeze usually requires annual filing. The state page says applicants file Form PTAX-340 with the Chief County Assessment Office each year.

Homestead Exemption for Persons with Disabilities

Illinois has a separate Homestead Exemption for Persons with Disabilities. The state describes it as an annual $2,000 reduction in EAV for the primary residence occupied by a person with a disability who is liable for the property taxes.

The person must be an owner of record or have a legal or equitable interest shown by a written instrument. For a leasehold interest, the lease must be for a single-family residence.

The state says the initial application is Form PTAX-343, filed with the Chief County Assessment Office with proof of disability. The annual verification form is PTAX-343-R.

This exemption generally cannot be received in the same year as the Veterans with Disabilities Exemption for Specially Adapted Housing or the Standard Homestead Exemption for Veterans with Disabilities. If more than one disability-related exemption might apply, ask the county which one fits.

Veteran exemptions in Illinois

Illinois veteran property tax exemptions are not for every veteran. Rules may depend on service-connected disability rating, active-duty return from armed conflict, surviving spouse status, World War II service, specially adapted housing, ownership, occupancy, and filing rules.

The Illinois Department of Revenue has a separate page on property tax relief for veterans and persons with disabilities. It directs homeowners to the Chief County Assessment Office for homestead exemption filing. For some specially adapted housing benefits, veterans or spouses may also need to contact a local Veteran Service Officer.

Standard Homestead Exemption for Veterans with Disabilities

This exemption is for a qualifying veteran with a service-connected disability certified by the U.S. Department of Veterans Affairs. The veteran must occupy the home as a primary residence, own or lease a single-family residence under the rules, and be liable for the property taxes.

The state lists these EAV reductions:

• 30% to 49% service-connected disability: $2,500 EAV reduction.
• 50% to 69% service-connected disability: $5,000 EAV reduction.
• 70% or more service-connected disability: the first $250,000 of EAV is exempt from taxation.

Some un-remarried surviving spouses may continue or transfer the exemption when the rules are met. State guidance also says that, for tax years on or after 2024, a veteran who was a member of the U.S. Armed Forces during World War II may have the property exempt regardless of disability level.

Bring the county the documents it asks for. In Cook County, the current Veterans with Disabilities Exemption page lists examples such as a DD Form 214 for first-time applicants and a VA disability certification letter.

Returning veterans and specially adapted housing

The Returning Veterans’ Homestead Exemption gives a $5,000 EAV reduction for a veteran’s principal residence after returning from active duty in an armed conflict involving the U.S. Armed Forces. The state describes it as applying for two consecutive tax years when residence rules are met. Applicants file Form PTAX-341 with the Chief County Assessment Office.

The Veterans with Disabilities Exemption for Specially Adapted Housing is different. The state describes it as up to a $100,000 reduction in assessed value for certain adapted housing owned and used by a veteran with a disability. It cannot be combined for the same tax year with the standard veteran disability exemption or the persons with disabilities homestead exemption.

Home improvements and disaster rebuilding

The Homestead Improvement Exemption may apply when a qualifying improvement or rebuilding increases the value of the homestead property. The Illinois Department of Revenue says the exemption is limited to the fair cash value added by the improvement, up to an annual maximum of $75,000, or $25,000 in assessed value, and continues for four years from completion and occupancy.

Illinois also has a Natural Disaster Homestead Exemption for rebuilt residential structures after certain widespread natural disasters. That is not the same as a normal remodeling exemption. Ask your county assessment office which process applies.

Renters and leaseholders

Most renters do not apply for Illinois homestead exemptions. If you rent an apartment and your landlord pays the property tax bill, a homeowner exemption is usually not your application.

There are narrow leasehold situations in Illinois homestead rules. If you lease a single-family residence and are legally responsible for property taxes, ask the county assessment office whether a leasehold homestead application is available and what written proof is required.

Where to file in Illinois

For most Illinois homeowners, the filing office is the Chief County Assessment Office, often called the Supervisor of Assessments. In some areas, the township or multi-township assessor is involved.

Cook County is different from many other counties because the Cook County Assessor uses its own exemption filing system and property lookup. For other counties, start with your county’s official assessment or supervisor of assessments page. The Illinois Chief County Assessment Officers directory can help you find the county office. The Illinois Department of Revenue also has a county contact page connected to property tax number information.

Documents to gather before applying

Exact documents vary by exemption and county. These are common items to gather before starting:

• Property address and Property Index Number, often called a PIN or parcel number.
• Property tax bill or assessment notice.
• Proof that the home is your principal residence.
• Proof of ownership, trust interest, legal interest, equitable interest, or qualifying leasehold interest.
• Government ID or proof of age for senior exemptions.
• Income proof for Senior Freeze filings, if required.
• Disability proof for the persons with disabilities exemption.
• VA disability certification letter and military records for veteran disability filings, if required.
• Death certificate, marriage proof, and ownership documents for surviving spouse filings.
• Closing statement if you bought or sold the home during the year.

Keep copies of everything you submit. Save online confirmations, mailing receipts, and screenshots.

Deadlines, renewals, and missing exemptions

Illinois timing can be confusing because property taxes are often paid in the year after the tax year. A county may talk about Tax Year 2025 exemptions on bills paid in 2026.

Look at the tax year on the form. It may ask about income from the prior calendar year or whether you occupied the home on January 1.

Some exemptions renew automatically after approval. Others require annual filing or annual verification. Senior Freeze filings are a common annual task. Persons with Disabilities filings require annual verification under state guidance. Veteran disability filings may require annual renewal unless current law or county instructions provide an automatic renewal path for a specific group.

If your application is denied

A denial may mean the county did not receive proof, the form was filed for the wrong tax year, the deed name did not match, the home was not shown as your principal residence, or income proof was incomplete.

Ask for the reason in writing if it is not clear. Then ask which official process applies. You may need to submit missing documents, correct the PIN, file a renewal instead of a first-time form, or use a county correction process for a prior year.

Cook County tells homeowners who believe they were entitled to exemptions in previous tax years that a Certificate of Error application may help recover missing prior-year exemptions. Other counties may use different procedures.

If the problem is a high assessment

A homestead exemption does not prove that the county valued your property correctly. If the assessed value is too high, you may need an assessment appeal.

The Illinois Department of Revenue explains on its assessment appeals page that an appeal challenges the assessed value, not the tax bill itself. Tax rates are not the issue in that appeal process.

Useful evidence may include recent sales of similar homes, an appraisal, property record errors, photos of condition problems, or proof that comparable homes are assessed lower. Deadlines are strict.

After a county Board of Review decision, the Illinois Property Tax Appeal Board may be involved in some assessment disputes. PTAB says it does not have authority to exempt property from taxation or review the amount of the tax bill or tax rate.

Exemptions are not deferrals, credits, rebates, or appeals

Illinois property tax relief words can sound similar. They work differently.

• Exemption: Reduces taxable assessed value.
• Freeze: In Illinois, the Senior Freeze freezes the EAV base, not the whole bill.
• Deferral: Delays payment and can create a lien, interest, and repayment duty.
• Credit: Usually reduces income tax, not the property tax bill itself.
• Rebate or refund: May return money after a separate application or tax filing, depending on the program.
• Appeal: Challenges the assessed value or official process.

Illinois has a Senior Citizens Real Estate Tax Deferral Program, but it is not a homestead exemption. The Illinois Department of Revenue’s senior deferral page describes it as similar to a loan against the property’s market value. Deferred amounts carry interest, and a lien is filed on the property. The deferred amount must be repaid when the property is sold or transferred, within one year of the taxpayer’s death, or within 90 days after the property stops qualifying.

A practical filing plan

1. Find your property tax bill or assessment notice.
2. Write down your PIN or parcel number.
3. Check your county property record to see which exemptions are already applied.
4. Go to your county assessment office’s official exemption page.
5. Choose the exemption that matches your situation.
6. Check the tax year and filing deadline on the county page or form.
7. Gather proof before starting.
8. Submit through the official county system, by mail, or in person as allowed.
9. Save proof that you filed.
10. Check the later tax bill to make sure the exemption appeared.

When to call the county office

Call the official county office if the home is in a trust, life estate, estate, or deceased spouse’s name; you moved during the year; you bought after January 1; you live in one unit and rent others; you are a surviving spouse; your income is close to the Senior Freeze limit; an exemption disappeared; you received a denial; or you are behind on taxes.

Exemption questions usually go to the assessment office. Payment, delinquency, tax sale, lien, and installment questions usually go to the county collector or treasurer.
