Kankakee County Property Tax Exemptions (and the Ones People Never Claim)

by Brian Wittman

In some Illinois counties the main homestead exemption lands on your tax bill without you ever asking for it. Kankakee County is not one of them.

Kankakee publishes an application form for it. That single fact is the most important thing on this page, because if you bought a house here and assumed the exemption showed up on its own, it may not have.

What property tax exemptions can lower my Kankakee County tax bill?

The main ones are the General Homestead Exemption, worth up to $6,000 off your equalized assessed value, the Senior Citizens Homestead Exemption, worth another $5,000 if you are 65 or older, and the Senior Freeze, which locks your assessed value in place if your household income is under the limit. There are also exemptions for veterans with service-connected disabilities, for homeowners with disabilities, and for anyone who recently finished a major improvement.

Two things make Kankakee different from the counties around it. You generally have to file for the homestead exemption rather than receive it automatically. And the dollar amount is smaller than the figure most people have heard, because the number that circulates online is usually Cook County's.

What is an exemption, and how is it different from an appeal?

An exemption lowers the taxable value of your home based on who you are or how you use it. You live there. You are 65. You are a disabled veteran. The county subtracts a set amount and you pay tax on the rest.

An appeal is an argument that the assessment itself is too high, that the county thinks your house is worth more than it is. Those are separate processes, and you can have both problems at the same time. If your number looks wrong, I laid out how to appeal your property taxes in Kankakee County separately.

Of the two, a missing exemption is the easier fix. Nobody is going to argue with you about whether you live in your own house.

The General Homestead Exemption, and the number that gets misreported

Up to $6,000 off your equalized assessed value if you own the home and occupy it as your principal residence as of January 1.

You will see $10,000 published in a lot of places, including some that look official. Here is why, and it is worth understanding rather than just taking my word for it.

The amount is set by state statute and it scales with county size. Under the Illinois Property Tax Code, the General Homestead Exemption is $10,000 in counties with three million or more people, $8,000 in counties that are directly next to one of those, and $6,000 everywhere else. Illinois has exactly one county over three million, and it is Cook.

Kankakee County has roughly 107,000 people, and it does not border Cook. So Kankakee lands in the third bucket, at $6,000.

The $10,000 figure is the Cook number. It travels because Cook is the biggest county and the loudest search result, and it gets copied onto pages about other counties.

You do not have to take anyone's word for it, including mine. Kankakee County's parcel lookup will show you the exemptions actually applied to your specific property. That is the version that decides what you pay, and it takes about a minute.

You have to apply for it, and that is where it gets lost

Kankakee County publishes an "Application for Homestead Exemptions" covering both the General Homestead Exemption and the Senior Citizen Homestead Exemption on one form, with a separate checkbox for each. If you bought a house here and nobody handed you that form at closing, there is a real chance nothing was ever filed.

Worth knowing, because you may read otherwise: the state statute technically says the exemption is granted automatically in any county under three million people, and Kankakee is well under that. But the county publishes an application anyway, which tells you how it works in practice. Practice is what determines what shows up on your bill, so file the form.

The form itself is short. It asks whether you were the owner of record or held a legal or equitable interest as of January 1, whether the property was your primary residence as of January 1, and what type of residence it is. It has to be signed by the owner of record, under penalty of perjury.

The Senior Citizens Homestead Exemption, and the rule nobody mentions

$5,000 off your equalized assessed value if you turn 65 during the assessment year, own the property or hold a legal or equitable interest in it, and are liable for the taxes. There is no income limit on this one. That surprises people, because the income limit attached to the Senior Freeze gets confused with this exemption constantly.

It shares a form with the General Homestead in Kankakee, so if you are 65 and just bought, you can file both at once.

Two details from the county's own form that are worth more than they look.

There is a pro-rata version. If the property first becomes your principal residence partway through the year, after January 1, you can receive a prorated senior exemption for that year rather than waiting until the next one. Almost nobody knows this. If a parent moved in with family, or downsized in June, that is real money that would otherwise sit unclaimed for a full cycle.

Bring proof of age. A valid birth certificate, a state driver's license, or a state ID card. People show up without it and have to come back.

Nursing home and life care facility residents can still qualify under stated conditions, and so can someone whose property remains unoccupied or is occupied by a spouse 65 or older. Those situations are common and they are more often eligible than families assume.

The Senior Freeze, and the income limit that just went up

If you only act on one thing here, make it this.

The Low-Income Senior Citizens Assessment Freeze does not subtract a fixed amount. It locks your equalized assessed value at a base year, so as values rise around you, yours holds. Over a decade that is worth more than every other exemption on this page put together.

The household income limit is climbing. It was $65,000 for tax year 2025. It is $75,000 for 2026, then $77,000 for 2027, and $79,000 for 2028 and after.

If you have a parent or a neighbor who applied a few years ago and was told they made too much, the answer may have changed. Ten thousand dollars of headroom opened up, and there is no system anywhere that goes back and notifies the people who were previously denied. They have to hear it from somebody.

And the hard part: it has to be filed every single year. Form PTAX-340, annually, meeting that year's qualifications. Skip one year and the freeze is gone, not reduced. It resets. It is the least forgiving exemption in the state, and it is the one most likely to vanish after a rough winter or a hospital stay when paperwork was not the priority.

What if you are a veteran, or living with a disability?

The largest dollar amounts on this page live here, and so does the biggest awareness gap.

Standard Homestead Exemption for Veterans with Disabilities. It scales with your VA service-connected rating. A 30 to 49 percent rating takes $2,500 off your equalized assessed value. A 50 to 69 percent rating takes $5,000. At 70 percent or higher the residence is exempt, though only the first $250,000 of equalized assessed value can be exempted. Since 2024, World War Two veterans qualify at 100 percent regardless of their rating.

Veterans with Disabilities Exemption for Specially Adapted Housing. Up to $100,000 of assessed value exempt on housing that was federally funded or donated and adapted for the veteran.

Returning Veterans' Homestead Exemption. $5,000 off for two consecutive tax years for a veteran returning from active duty in an armed conflict.

Homestead Exemption for Persons with Disabilities. $2,000 off, and it requires annual verification after the first filing. Annual, like the Senior Freeze, so the same warning applies.

Unmarried surviving spouses can carry several of these forward. The rules differ by exemption, so that is a phone call and not an assumption.

The Homestead Improvement Exemption

If you finished an addition, a rebuild after a catastrophe, or a significant improvement, up to $75,000 of the new fair cash value it added can be shielded for four years.

The four-year window runs from completion, not from when anyone notices. If you did permitted work in the last few years and never saw an adjustment, ask about it before the clock runs out. There is also a Natural Disaster Homestead Exemption for a residence rebuilt after a widespread disaster, filed annually.

How do I check what I am actually getting?

Look at your tax bill first. The exemptions applied to your property are itemized on it.

Then use the county's parcel and tax lookup and pull your own address. It shows what is actually on your property right now, which beats any published summary including this one. If the General Homestead is not there and you live in the house, you found your problem.

I want to be straight about a limit here. I could not verify from a primary source whether Kankakee requests the application from every new buyer at closing or only when someone asks. That distinction matters if you bought recently, and the office can answer it in one call. I would rather tell you that than guess.

How and when do you file?

You file with the Supervisor of Assessments, which is the office's actual name in Kankakee County rather than "county assessor," a distinction that will save you a transferred phone call.

Kankakee County Supervisor of Assessments 189 East Court Street, Kankakee, IL 60901 (815) 937-2945

The county's homestead application form states a filing deadline of December 31 of the assessment year. I want to flag one thing about that: the form references the 1997 Property Tax Code and the attached state form is a 2017 revision, so the document may have been sitting a while. The December 31 date is what the county publishes, and I would work to it, but if you are filing close to the wire, confirm it by phone rather than trusting a form or an article.

The Senior Freeze is separate and annual, on Form PTAX-340. The state's plain-language summary of every Illinois exemption, with current amounts, is at the Illinois Department of Revenue.

Why this matters over the next five to ten years

An exemption is not a one-time credit. It repeats every year you own the house, which is what makes a missed one so expensive over time.

Run the Senior Freeze out. Qualify at 66, hold the house into your late seventies, and you have not saved one year of increases. You have sat out a decade of them while assessed values moved around you. The gap between your frozen number and the market number widens every year, which is the entire point, and it is why losing it to one missed form is so much worse than it looks on a single bill.

There is a monthly cash flow piece too. If your taxes are escrowed, adding an exemption does not drop your payment right away. It changes your escrow analysis, and the payment follows at the next review. Worth knowing so you are not confused when nothing moves the month after you file. I walked through that in why your escrow payment went up.

And if you are trying to work out why the bill looks the way it does in the first place, exemptions are only one lever. The rate and the assessment move the number too, which I covered in Illinois property taxes and what they actually do to your budget.

The Bottom Line

In Kankakee County the homestead exemption has a form, and forms get skipped. If you bought here and never filed one, start by pulling up your parcel and seeing what is actually on it.

The General Homestead is $6,000, not the $10,000 you will see published in places. That figure belongs to Cook County. Your own parcel record settles it faster than any argument.

If you are 65 or older, the Senior Citizens Homestead has no income limit and can be prorated in the year you move in, and the Senior Freeze income cap just went to $75,000 on its way to $79,000. If someone told you no a few years ago, that was a different rule.

None of this needs a lawyer or a paid service. It needs a form and a deadline. If you want a second set of eyes on your bill before you file, I am glad to look.

Frequently Asked Questions

How much is the homestead exemption in Kankakee County?

Up to $6,000 off your equalized assessed value. The $10,000 figure you may see published is the Cook County amount. Illinois sets the exemption by county size, at $10,000 for counties over three million, $8,000 for counties bordering one, and $6,000 for everyone else.

Do I have to apply for the homestead exemption in Kankakee County?

Kankakee County publishes an application form for it, covering the General Homestead and Senior Citizen exemptions together. If you bought here and never filed anything, check your parcel record before you assume it is on there.

What is the income limit for the Kankakee County Senior Freeze?

$75,000 in household income for tax year 2026, rising to $77,000 for 2027 and $79,000 for 2028 and after. It was $65,000 for 2025, so people denied under the old limit may qualify now.

Is there an income limit for the senior exemption in Kankakee County?

No. The Senior Citizens Homestead Exemption has no income limit. The income limit that people are thinking of belongs to the Senior Freeze, which is a separate program.

When is the deadline to file for a Kankakee County exemption?

The county's homestead application form states December 31 of the assessment year. The Senior Freeze runs on its own annual cycle. Because the form is not recently revised, confirm the current date with the Supervisor of Assessments at (815) 937-2945 if you are filing close to the deadline.

Can I get a senior exemption if I moved in partway through the year?

Yes, on a prorated basis. If the property first became your principal residence after January 1, the county's own form provides for a pro-rata senior citizens homestead exemption for that year rather than making you wait for the next cycle.

What do I need to bring to apply for the senior exemption?

Proof of age, meaning a valid birth certificate, a state-issued driver's license, or a state ID card. You also have to be the owner of record or hold a legal or equitable interest, and sign the application yourself.
