Your appeal is about your property's assessed value. Your property's assessed value is based on the Assessor's estimate of your property's fair market value. In Cook County, your Class 2 residential property is assessed at 10 percent of its estimated property value. The estimated property value is determined by analyzing sales information of similar homes in your area. For example, an estimated property value of $100,000 would calculate to an assessed valuation of $10,000. Class 2 properties include detached single-family houses, townhomes, condominiums, cooperatives, and multi-family residential buildings with no more than six dwelling units. (Separate instructions are available for condominiums and cooperatives.) Your appeal is how you let us know that you think the assessed value for your property is not fair and accurate.

It's a common misconception that your appeal is a "tax appeal." Keep in mind, the Assessor does not calculate taxes. Local governments, such as municipalities and school districts, determine the overall amount of real estate taxes collected in your community. It is important that your assessed valuation be accurate and fair, as it does play a role in determining your share of those taxes.

Three common grounds for appeals are listed below:

1. Uniformity Appeal:

   If you are concerned that the assessed valuation of your home is not uniform with the assessed valuations of other similar homes, compare your property to similar homes. This comparison will help you determine if you have reason to file a uniformity appeal.

   There are two ways to do this:

   1. Simply fill out the appeal form, indicating that the purpose of the appeal is "lack of uniformity". You do not need to research and find your own comparable properties in order to file an appeal with our office. Our analysts will check properties comparable to yours to determine if your assessed value is in line with the assessed values of those properties.

   2. If you wish to include a list of comparable properties with your appeal, please follow the gudielines below:

      • For your convenience, all residential assessments will be published in a local community newspaper a few days after you receive your reassessment notice. The name of the newspaper and date of publication are indicated on your notice. The assessment listing will also be available at your local library.
      • When choosing comparable properties, select homes within your neighborhood code that closely resemble your own home in both size and style. If the Permanent Index Numbers (PINs) are not known, the Assessor's staff will assist you in obtaining this information. You may also use the residential data books located in all of our offices to check if the comparable assessed values are in line with your assessment. If the assessed value of the comparable properties that you have chosen are lower than your property's assessed value, you may have reason to file an appeal.
      • You may also find the assessed values of comparable properties by visiting the assessor's Web site property search. Pictures of nearly every Cook County property may also be found there.
      • Write the PINs that you have found to be comparable on the appeal form that you file. Our analysts will use your information, along with our office data, to determine if the assessed value of your home is in line with the assessed values of comparable properties.

2. Overvaluation Appeal:

   You may also wish to file an appeal if you believe our estimate of the property value is overvalued for any reason. You are encouraged to submit supporting documentation, such as recent closing statements or purchase prices of homes similar to yours, along with your appeal.

3. Property Description Error Appeal:

   Finally, if there is an error in the description of your property, such as incorrect square footage of living area or an error that you believe may affect property value, you may wish to file an appeal. However, a minor error does not necessarily indicate an incorrect assessment.

It is the policy of the Cook County Assessor to assess all real property in a fair and uniform manner consistent with the legal responsibility placed on the Office of the Assessor. It is also our policy to provide everyone equal access to the remedies afforded by the appeal process. In accordance with these policies, the Office of the Assessor shall provide experienced personnel to assist property owners who want to appeal their assessed valuations.

You will receive a reassessment notice in the mail when the Assessor's Office reassesses your home every three years. This notice contains a proposed assessment which will be reflected on your subsequent year’s second-installment tax bill. It also contains our data about your property's characteristics, like its square footage. For residential homes, we use these characteristics to produce your property value.

Once you have received your notice, you have approximately 30 calendar days to file an appeal with our office. The last date to file an appeal is printed on the top of your notice. You may also appeal your assessed valuation in any year between reassessments when your property's township is open for appeals.

Appeals can be filed when your township is open for appeals. To file an appeal online, find your property via our Property Search. If you cannot file an appeal online, prefer to visit one of our offices, or want to mail your appeal, you must use an official "Real Estate Assessed Valuation Appeal" form. Please submit one copy and keep another copy for your files. You do not need a lawyer, tax representative or appraiser to file an appeal on the assessed valuation of your home. If your appeal is filed by an authorized representative, an "Owner/Lessee Verification Form" must be completed, notarized and filed along with the appeal form. Note that your appeal must be filed within your township deadline, posted on our Assessment Calendar and Deadlines page.

A “comparable property” is a property located within your assessment neighborhood which has characteristics similar to those of your property. These characteristics may include property classification, building age, building square footage, land square footage, and exterior construction. A complete list of your property's characteristics can be found in the “property characteristics” section when your PIN number is entered.

It is important to note that the Assessor's Office uses neighborhood codes to distinguish between various neighborhoods within townships. If you choose to perform your own search for comparable properties, you should attempt to find comparable properties located within your assessment neighborhood. You should also try to locate comparable properties which have the same property classification as your property.

To file an appeal now, use the Property Searchon this Web site and click on Appeals. Once there, complete the information and file the appeal. If you do not see a form at this point then that means your township is not open to submit appeals. You may also file an appeal at our office, your local township office, or you may request that an appeal form be mailed to you. Experienced personnel are available at all of our offices to help you in filing your appeal. Please have your reassessment notice handy because it contains important information that may be needed for your appeal.

You may a request for a re-review. Get the form here.If you wish to appeal your assessment further, you may also file an appeal with the Cook County Board of Review (312-603-5542).

A Real Estate Certificate of Error (C of E) allows the Cook County Assessor to change a property’s assessed value. Illinois law provides this procedure as a way to correct a tax bill after the assessment for that tax year is finalized. A Certificate of Error addresses a single year. If you are entitled to a value reduction for more than one year, a Certificate of Error request must be filed for each individual year.

After a C of E application is received, it must be processed through the Assessor’s Office. If the property’s assessment has been previously reviewed by the Board of Review, the Board of Review must approve the C of E as well. In addition, non-residential C of E requests that seek a reduction of more than $100,000 in assessed value must be sent to the Circuit Court for a judge’s consideration. If a Certificate of Error does not have to go to court for review, you will receive a letter from the Assessor’s Office which indicates whether the Certificate of Error has been granted or denied. If the C of E is required to go to court for adjudication, a letter regarding the outcome of that C of E request will be sent to you by the Cook County State's Attorney’s Office.

Certificate of Error application forms are available on the forms page of the Assessor’s Web site or by calling (312)443-7550.

Residential property owners who experience severe damage to their homes as a result of a catastrophic event are eligible to receive a home improvement exemption of up to $75,000.

This exemption is available when a residential structure is rebuilt after a catastrophic event. The exemption applies to the difference between the increased value of the rebuilt structure and the value of the structure before the catastrophic event.

The residential structure must be rebuilt within two years after the catastrophic event. The exemption will continue for four years following completion or until the next reassessment, whichever is later.

Catastrophic events are defined as severe damage or loss of property resulting from any catastrophic cause including but not limited to fire, flood, earthquake, wind, storm, explosion or extended periods of severe inclement weather. In the case of flooding, the structure must be located within a jurisdiction which is participating in the National Flood Insurance Program.

To file for a Catastrophic Event Exemption, the property owner or authorized representative must complete a Residential Assessed Valuation Appeal form.

Along with the appeal form, it is necessary to submit the following materials:

• a written description of the damages and the dates when damages occurred,
• the estimated date of completion for repairs or rebuilding, and
• all pertinent records such as photographs, insurance reports, building permits and occupancy certificates.

Appeal forms and documentation may be filed by mail or in person.

An appeal may only be filed while the Assessor’s Office is accepting appeals for your township.

It is the policy of the Cook County Assessor to assess all real property in a fair and uniform manner consistent with the legal responsibility placed on the Office of the Assessor. It is also our policy to provide everyone equal access to the remedies afforded by the appeal process. In accordance with these policies, the Office of the Assessor shall provide experienced personnel to assist property owners who want to appeal their assessed valuation.

With the exception of Class 2 residential properties for which separate rules have been issued, the Office of the Assessor has prepared these rules to assist all Cook County property owners in pursuit of any claim of over-assessment.

Illinois law requires the Assessor to place an assessed valuation on all real property located in the county. The law also gives property owners the right to challenge the values set by the Assessor. Under the law, property owners must submit evidence sufficient to justify a reduction in assessed valuation.

Supplemental bulletins have also been prepared by the Office of the Assessor to specify the type and extent of proof which will assist in preparation of appeals for specific types of properties. These bulletins contain significant details and information which will assist in the presentation of an over-assessment claim. There are also extensive bulletins explaining eligibility requirements for the Cook County Incentives Program for certain industrial, commercial and residential properties (Classes 6b, 6c, 7a, 7b, 8 and 9 and L). These bulletins should be carefully reviewed when filing applications and appeals seeking eligibility under any of these incentives. Inquiries may be directed to the Incentives Department (312-603-7529).

So as to avoid hardship or injustice, the Assessor or his designated representative may waive any technical requirement in these rules.

The Assessor's staff can assist in answering questions regarding filing an appeal. (312) 603-7526

Owners of commercial properties and businesses may wish to consult with members of the Assessor's staff for assistance in preparing an appeal. Inquiries may be directed to an industrial/commercial specialist at 312-603-7526.

Notice appeals may be filed at any time within the filing period of 30 calendar days beginning with the date Notices of Proposed Assessed Valuation are issued for the township in which the subject property is located.

The Office of the Assessor has a policy for certain properties (you will be told if your property falls under this category) in which a letter request for pre-valuation information and documentation is substituted for the initial reassessment notice. This program is an effort to have access to information generally unavailable to the Assessor so as to arrive at a more accurate and fair initial assessed valuation. The property owner is given an opportunity to file an appeal with the requested documentation setting forth the property owner's estimate of market value and reasons in support thereof. This program is being expanded as more comprehensive automation of the Assessor's record base is completed.

The following documents may be required to initiate an appeal. Please refer to the respective Class Bulletin for more information.

1. Real Estate Valuation Appeal form

   This form must be completed in its entirety and shall contain:

   1. name and address of the owner of the property;
   2. common address, township and permanent index number(s) of the property;
   3. total consideration paid for the property if purchased within the last five years;
   4. owner’s estimate of the current fair market value of the property;
   5. brief description of basis of alleged over-assessment, and
   6. signature of owner or authorized representative.

2. Property Summary Sheet

   One copy of the Property Summary Sheet for the subject’s property type (commercial/industrial etc.) must be completed. Consult the Assessor’s bulletins for specific information.

3. Owner/Lessee Verification Affidavit

   In addition to the appeal form being completed as described above, one copy of the Owner/Lessee Verification Affidavit must be completed and notarized where required, and submitted with the valuation appeal form at the time of filing. This now requires an identification of the taxpayer as the owner or lessee of the property and the property’s common name. This form requires the taxpayer to declare whether the property in question was purchased within the last five years, and if so, to state the purchase price and date of sale and verify the income expense statements of the operations.

   Appeals which are not accompanied by a fully completed Owner/Lessee Verification Affidavit when required, may be denied.

4. Industrial/Commercial Sales Questionnaire

   This is necessary when subject property has been purchased within the last five years. For properties purchased within the past five years, one copy of the Sales Questionnaire must be completed and submitted with appeal documents.

   Failure to file these required forms and submit the purchase information and supporting documentation discussed below, will delay action on the appeal and may cause the Assessor's Office not to act on the appeal.

5. Field Check Request (if applicable)

6. Appraisal Summary Sheet (if applicable)

7. Vacancy Affidavit (if applicable)

   More Content & Supporting Documentation

   For all property, except Class 2, a short and concise narrative explaining the reasons for the claimed over-assessment must be prepared and filed with the appeal form. Sufficient valid documentation should accompany the factual statement to support all conclusions of fact, law and valuation set forth in the appeal.

   It is suggested that the Assessor's bulletins be consulted for recommendations as to the degree and quality of documentation. Specific proof may be presented for specific types of property and/or situations.

   All supporting documentation should be submitted at the time the appeal is filed. Please Note: If a field check is required, it must be requested at the time that an appeal is filed. Appeals lacking documentation will be held an additional 15 days beyond the filing deadline, at which time they will be denied if not complete. (Note: The Assessor’s Office will post any extension to this time deadline).

   In the following instances, the supporting documentation is the same for all types of properties.

   If the property which is the subject of the appeal has been purchased or transferred within the last five years, the purchase or transfer must be disclosed and the purchase price and the terms of the purchase fully documented by submitting all pertinent documents. This includes, but is not limited to, signed copies of the purchase contract, the closing statement and the real estate transfer declaration.

   All appraisals must also disclose any purchase or other transfer of the subject property within the last five years and shall address its effect, if any, upon any opinion of value reported in the appraisal. If the complainant requests a removal of an improvement from the assessment roll, the complainant must submit an affidavit as well as copies of the demolition permit, the paid demolition bill and any other documentation that will establish the date and the extent of the removal of the improvement.

   If the property is partially occupied rental property, year to date income and expense statements and/or current rent rolls shall accompany vacancy affidavits.

   Supplemental documentation may be requested by the Assessor’s Office.

Any affidavit should provide the following:

1. identity of the person verifying the facts and indication that the person possesses sufficient knowledge of said facts;
2. identification of the property about which said facts are alleged;
3. time period as to which said facts are being alleged;
4. person verifying said facts signs the affidavit in the presence of a commissioned notary public.

Affidavits as to the accuracy of income and expense statements, vacancy levels and demolition are required and are to be completed on forms provided by the Assessor's Office.

A Certificate of Error request is initiated in all cases except exemption claims by filing a current assessment year appeal accompanied by a Certificate of Error application for each tax year requested. The request for a Certificate of Error should also be marked on the appeal form with the basis of the Certificate of Error noted in the explanation box. The same rules and recommendations for affidavits and supporting documentation on a current appeal apply for a Certificate of Error.

One set of documentation supporting the Certificate of Error must accompany each current appeal and one additional set of documentation must be filed for each tax year for which a Certificate of Error is being requested.

It is recommended that a Certificate of Error request for a valuation reduction on industrial/commercial and residential properties be supported by a competent appraisal, limited scope appraisal, letter of value, income/expenses and claim of a factual error.

If a Certificate of Error request is based on vacancy relief or a classification change one detailed affidavit from the owner is required. In certain instances, utility bills, rent rolls, IRS schedules, fire reports, demolition affidavits or a second party affidavit may be requested by the Assessor’s Office.

Exempts

All requests for Certificates of Error based on a claim for exempt property shall be filed in the Assessor's Exempt Department. However, a current assessment year appeal must be filed in all cases where valuation of a partially exempt entity is contested.

The appellant will be notified by mail of the result of the appeal. If the appellant is dissatisfied with the result, reconsideration may be sought upon timely submission of a written request which details in brief and specific terms the basis for reconsideration. All such requests for reconsideration should be addressed to the Chief of Assessment Operations.

Taxpayers requiring assistance with commercial/industrial appeals may consult one of the assessor’s industrial/commercial hearing specialists at 312-603-7526. They may also receive assistance at the assessor’s downtown office and at all suburban branch offices.

If you elect to file as an individual unit owner, the following information should accompany your appeal:

1. The closing statement if the unit has been sold within the last five years;
2. A copy of the local municipality’s occupancy permit if the unit is newly constructed or converted;
3. The percentage of ownership of the individual unit, and if presented, the percentage of ownership of comparables.

A joint appeal filed by the Association or Board on behalf of all condominium owners is the most effective way to appeal the valuation of any condominium building(s).

There are three advantages to filing a joint appeal:

1. market forces that affect the value of an individual condominium unit will have a similar affect on the other units as well;
2. the percentage of ownership assigned to each unit is a major valuation factor; and
3. the Association or Board is most likely to have access to relevant sales information.

The following information must accompany each joint condominium valuation appeal:

1. A copy of the original declaration of condominium ownership with all subsequent amendments;
2. A list of all unit numbers, and the corresponding permanent index numbers, which are subject to the terms of the declaration. Include all property owned by the Association or Board, including recreational, parking, or other facilities, whether adjacent or not;
3. A description of the size of each unit, the unit blend of the building(s) and the percentage of ownership of each unit;
4. Interior and exterior photographs of the building(s);
5. The closing statements for all units which have been sold within the last five years;
6. Actual construction or renovation cost information if the building(s) has been constructed, converted or renovated within the last three years; and
7. Three years of financial statements if the building(s) has been constructed, converted, or renovated within the last three years.

In the case of cooperative buildings, a joint appeal must be filed by the Board because there is only one assessed valuation for the entire cooperative property.

The following information must accompany each cooperative valuation appeal:

1. A copy of the cooperative’s Articles of Incorporation and all other rules and regulations which concern the length of proprietary leases and the sales or transfer of shares;
2. All ground lease information, if applicable;
3. A complete legal description of the cooperative’s property including a list of permanent index numbers of all property owned by the cooperative including recreational, parking or other facilities, whether adjacent or not;
4. A description of the size of each unit and the unit blend of the building(s);
5. Interior and exterior photographs of the building(s);
6. Any information relating to the number of shares or percentages of ownership assigned to each unit;
7. Any information relating to the number of outstanding shares;
8. Any information relating to any purchase contracts, or sales, transfers or assignments of beneficial interest of any shares or percentages of ownership in the cooperative within the last five years;
9. Actual construction or renovation cost information if the building(s) has been constructed or renovated within the last three years;
10. Three years of financial statements which include the year-end mortgage balance, and income and operating expense information.

You can receive the Homeowner Exemption if you own or have a lease or contact which makes you responsible for the real estate taxes of the residential property. It must also be used as your principal place of residence for the year in question.

This exemption will be prorated if you purchased a newly constructed home that was not ready for occupancy until sometime after January 1 of the tax year in question. For further assistance, call our Taxpayer Services Department at (312) 443-7550. If you have never received a Homeowner Exemption on your home, you will need to apply for one. Exemption forms may be obtained by calling or visiting one of the Assessor’s Office locations or your local township assessor.

The Home Improvement Exemption allows you to increase the value of your home with up to $75,000 worth of improvements without increasing your property taxes for at least four years.

The exemption is available to owners of single-family homes, condominiums, cooperatives, and apartment buildings up to six units.

You do not need to apply for the Home Improvement Exemption. The building permit you take out to complete the work on your home will automatically generate a field inspection of your property. A notice will be sent to you after we complete the field inspection.

The Home Improvement Exemption can also be used for repair necessitated by structural damage as a result of severe weather conditions such as flooding.

The exemption is not granted for loss of personal property, normal weather damage, or routine maintenance. Routine maintenance includes repairs to or replacement of parts that would not increase the value of your property. The following are examples of normal upkeep:

• Repair or replace roofing materials, sidewalks, driveways, or fencing
• Insulate and/or add storm windows and doors
• Add or replace gutters and downspouts
• Place siding over existing frame structure
• Add or improve trees, lawns, and landscaping
• Paint, decorate, plaster, or change exterior ornamentations
• Replace furnace, or replace old heating systems with solar heating
• Replace kitchen cabinets, flooring, fixtures
• Replace or add water softener, or add larger hot water heater
• Add outdoor lighting, burglar or fire alarms
• Replace electrical systems or plumbing fixtures
• Install above-ground swimming pool or outdoor playground facilities
• Add automatic garage door opener
• Add aluminum soffit and fascia

To learn whether you may qualify for the Home Improvement Exemption, call the Cook County Assessor's Office at 312/443-7550.

What is the Longtime Occupant Homeowner Exemption?

The Longtime Occupant Homeowner Exemption enables you to receive an expanded Homeowner Exemption with no maximum exemption amount. 

Who qualifies for a Longtime Occupant Homeowner Exemption?

Requirements for the Longtime Occupant Homeowner Exemption for Tax Year 2019 state that you must have

• Owned and occupied your residence from January 1, 2008 to January 1, 2018
• A total household income of $100,000 or less for income tax year 2016 and
• An assessment increase for your property that was significant enough to exceed the maximum amounts set by the state legislature.

When do I apply for the Longtime Occupant Homeowner Exemption?

Applications were mailed early this year to those properties which qualified.

Please note: Of the over 1.5 million residential properties in Cook County, fewer than two percent (2%) qualified for the Longtime Occupant Homeowner Exemption last year. This is due to the way the state legislature wrote the provision and the requirements they put in place in order to qualify.

Simply put, would-be savings from the Longtime Occupant Homeowner Exemption would have to exceed the savings from the Standard Homeowner Exemption. This does not happen for more than 98% of residences in Cook County.

The Cook County Assessor?s Office wants all homeowner/occupants to receive the maximum exemption savings to which they are entitled. If we calculate that the Longtime Occupant Homeowner Exemption would provide the most savings for a home, we automatically mail an application.

Please note: Properties not eligible to receive this exemption are automatically eligible to receive the full benefits of the standard Homeowner Exemption.

We value the contributions that religious organizations make to our communities. In an effort to protect the properties of these institutions, the government offers exemptions that eliminate all or a portion of their tax burden. The money saved on taxes can then be reinvested in the organization in order to benefit the surrounding community and its citizens.

This search page can be used to check the most current information available regarding the religious property’s exempt status. You can also view an image of the property.

There are 38 townships in Cook County. Each parcel of land is located in a certain township. Assessment notices are mailed out in a set order according to township. You can view the order of this mailing by going to (Appeal & Closing Deadlines). After the assessment work for a township has been completed and all appeals have been filed and analyzed, the assessments for that particular township are complete and the township is "closed" by the Assessor's Office. When a township is "closed" the status and value of all property in that township is final for a particular tax year.

You can check to see if the township where your property is located is "closed" by going to (Appeal & Closing Deadlines). If there is a date in the column entitled A Roll Published, your town is closed for appeals. This means that the exempt status shown is for the current. If there is no date in this column, the exempt status shown is for current year. As each township closes, the information on this Web site will be updated. Once your property is exempt, you do not have to file an annual affidavit to maintain your exempt status. You must notify our office if there is any change in ownership or use of the property.

Important Notice

1. If you have received an Exemption Certificate from the Illinois Department of Revenue and your PIN does not appear on this list, please contact our Exempt Department at 312-603-5499.
2. If an Exemption Certificate has not been issued by the Illinois Department of Revenue, your property is not exempt.
3. Taxpayers must respond to any correspondence from the Cook County Treasurer or Cook County Assessor’s office even if they believe that their property is exempt.
4. IF YOU HAVE RECEIVED A TAX BILL FOR ANY TAX YEAR, DO NOT IGNORE THE BILL. ALL BILLS SHOULD BE PAID IN ORDER TO FULLY PROTECT YOUR INTEREST IN THE PROPERTY.

This information is provided to help taxpayers check the most current status of their properties. This does not guarantee that there are no taxes outstanding on the property or that the property will continue to be exempt in future years. In order to check the status of current taxes due or paid, go to www.cookcountytreasurer.com. In order to check the status of prior taxes due, contact the Cook County Clerk at 312-603-5656.

Please read the following instructions for information on how to best conduct a search for exempt property.

• Request an application for exempt status.
• Complete and return the application to the Board of Review, providing the necessary documentation of exempt ownership and/or use.
• Remember: An application may include more than one Permanent Index Number (PIN) but the applicant must still file for each parcel of property.

Your application and accompanying documentation, along with the Board of Review’s recommendation, is then sent to the Illinois Department of Revenue for a decision. This stage of the process may take anywhere from six months to a year. While an exemption application is pending, the taxes for that tax year are protected from sale.

Step 2a

• If the exempt status isnot approvedthen churches may request a formal review by the Illinois Department of Revenue (800) 732-8866.

The Senior Freeze Exemption provides tax relief to eligible homeowners who meet age and income requirements (see below) and whose homes have drastically increased in value. It allows qualified seniors to apply to "freeze" their home's equalized assessed value (EAV) for the year in which they apply and qualify. This means that in future years, their property tax bill is calculated on the current year's EAV, but the previously "frozen" EAV. Those who qualify for and receive this exemption should be aware that it does not automatically freeze the amount of the tax bill. Only the EAV remains at the fixed amount. The local tax rates set by local municipalities, and how much a home has increased in value, can affect how much the Senior Freeze Exemption reduces a tax bill.

To qualify for the taxable year 2019 (billed in 2020), you must meet all of these requirements:

• Be born prior to or in the year 1954,
• Have a total gross household income of no more than $65,000 for 2017,
• Own the property, or have a legal, equitable or leasehold interest in the property on January 1, 2018 and January 1, 2019,
• Been liable for the payment of 2018 and 2019 property taxes, and
• Used the property as a principal place of residence on January 1, 2018 and January 1, 2019.

Those who are currently receiving the Senior Freeze Exemption will automatically receive a renewal application form in the mail, typically between January and April. You must file each year in order to continue to receive the Senior Freeze Exemption and the requirements must be met each year.

First-time applicants are encouraged to contact us to ensure eligibility, and if eligible, to apply between January and April.

Senior Citizen Real Estate
Tax Deferral Program
Cook County Treasurer's Office 312/443-5100

The Senior Exemption provides tax relief by reducing the equalized assessed value (EAV) of an eligible residence by $8,000. The amount your tax bill is reduced depends on your home's EAV and your local tax rate. This savings is in the form of a deduction on the second-installment real estate tax bill.

No. Seniors receiving the Senior Exemption automatically qualify for the Homeowner Exemption and do not have to apply for it separately.

No. This is a recent change. Until 2019, state law required that senior citizens reapply annually for the Senior Exemption. The law changed on August 26, 2019 with the signing into law of HB 833. The bill, championed by Cook County Assessor Fritz Kaegi and Illinois House Assistant Majority Leader Fred Crespo, amends the Illinois Property Tax Code to allow for the automatic renewal of the Senior Citizen Exemption for persons who had received this exemption in the year prior. Seniors not currently receiving the exemption, and those who turned 65 in 2019, must apply for the senior exemption in 2020; their exemption will then automatically renew each following year. Senior exemptions currently in place will renew automatically. If you received a Senior Exemption on the second-installment tax bill you received in July 2019, you do not have to reapply for this exemption.

To qualify for the Senior Exemption the property owner must be:

• using the property as their place of residence,
• 65 years of age or older during the tax year for which they are applying, and

Veterans with Disabilities Exemption.

Veterans with a service-connected disability as certified by the U.S. Department of Veterans Affairs are eligible for this annual exemption. It reduces by certain amounts the Equalized Assessed Value (EAV) on a the primary residence of a veteran with a disability, very likely lowering the tax bill.

It is very important to note that the Equalized Assessed Value (EAV) is not the amount of your taxes. The EAV is only the partial property value on which your taxes are computed; any reduction in EAV is not the dollar amount by which your tax bill may be lowered.

Veterans whose level of disability is 30% are eligible for a deduction from the EAV of their primary residence. The amounts of those EAV deductions range from $2,500 to $5,000. Veterans 70% or more disabled are totally exempt from property taxes.

Exemption amounts in the Veterans with Disabilities Homeowner Exemption are:

• own and occupy the property as the primary residence as of January 1, 2018,
• have a total EAV of less than $250,000 for the primary residence, excluding the EAV of property used for commercial purposes or rented for more than six (6) months and
• apply for this Exemption each tax year

A non-remarried surviving spouse of a disabled veteran may continue to receive this exemption if the same primary residence continues as such for the surviving spouse. Or, the non-remarried surviving spouse may transfer the exemption amount (or less) to a new primary residence.
