Many Exemptions Automatically Renew this Year

Exemptions reduce the equalized assessed value (EAV), or taxed value, of a home. Deductions will appear on the second installment bills issued in summer 2021.

Due to COVID and for the safety of constituents, many exemptions will automatically renew for tax year 2020. Households will receive a letter than confirms the auto-renewal of exemptions. Cook County Assessor has changed application process to electronic, hard copy exemption forms are not available. For those who are newly qualified for the Senior Exemption (born in 1955), or who have recently moved and need to apply go to Click on Exemptions, chose the appropriate exemption from the drop-down screen and click Apply on lower left of screen. This will take you to a DocuSign process.

For further information and to see which exemptions were applied to a property last year go to and click on Exemption History and Status for property details.

Exemptions that automatically renew for Tax Year 2020:


Cook County has increased the exemption amounts as of tax year 2017.

The homeowner exemption is $10,000 off the EAV or 10,000 X the local tax rate.

The senior exemption is $8,000 off the EAV or 8,000 X the local tax rate.

The county has increased the income limitation allowing up to $65,000 gross household income from the previous income tax year. The senior freeze is a minimum $2,000 off the EAV - or 2,000 X the local tax rate. Therefore, all seniors who qualify based on their household income will see a reduction.




A law recently passed that no longer requires seniors in Cook County to renew the senior exemption yearly. Under the new law, seniors who currently receive the senior exemption need not reapply, the exemption will automatically renew annually.

Seniors not currently receiving the exemption and who turn 65 in 2019 must apply in 2020. It will then automatically renew in future years. Forms will be available in early January on the Assessors website

The requirements for the Senior Freeze remain unchanged; the property owner must reapply each year.

Homeowners who were born in 1954 and turned sixty-five in 2019 do not receive senior application forms.  A first-time applicant must complete the 2019 Homeowner/Senior Exemption application or the 2019 Senior Freeze application and attach a copy of the most recent property tax bill and a current driver's license or a valid Illinois State I.D. at the address of the subject property.  The forms are available online at or from our office.  They can be mailed to the address on the form or dropped at our office for forwarding to the Cook County Assessor's office.

Eligibility for 2019 Senior Citizen Exemptions (Born in 1954 or Earlier)

There are two senior citizen property tax exemptions; both forms will be available on the Cook County Assessor website in early January, 2020.

  1. The Senior Exemption, available to all seniors regardless of income, reduces the Equalized Assessed Value on your 2nd Installment bill by $8,000.  That can equate to a savings of $700 or more annually on the property tax bill. This exemption automatically renews unless a sale or death occur.

      2. Senior Freeze may provide some seniors with additional savings if the combined gross income              of all occupants in a senior's household is less than $65,000 (for income tax year 2018), and if                the senior has been an owner-occupant of the house since January 1, 2018. The senior freeze                does not freeze the total amount due each year. It freezes the total assessed value. You are still              subject to the state equalizer and local tax rate changes each year. 

Exemptions can only be taken on one property, and that must be the owner's principal residence. One senior/senior freeze exemption per household is permitted.  If you have questions, need a form or help in completing the form, please contact us at 847-259-1515, or visit the Wheeling Township Assessor's office. We ask that you always have the 14-digit Property Index Number (PIN) available when you call or visit with any property tax questions.  The PIN can be found at the top of your property tax bill.


Veterans with 30%-49% service connected disability receive $2,500 reduction in the equalized assessed value (EAV).

Veterans with 50%-69% service connected disability receive $5,000 reduction in the EAV.

Veterans with 70% or more service connected disability are completely exempt from property taxation on their primary residence UP TO A 250,000 EAV.


The Disabled Persons' Homeowner Exemption provides an annual $2,000 reduction in the EAV of the property. The property must have been owned and occupied on January 1 of the assessment year by a disabled person who is liable for the payment of property taxes.

Township Assessors do not assess property in Cook County.  The Cook County Township Assessors including Wheeling Township are not funded or controlled by the County Assessor.  Assessment levels for all properties are set by the Cook County Assessor.  The Wheeling Township Office cooperates with the Cook County Assessor's Office in order to assist the taxpayer - you. We serve as your Taxpayer Advocate.

The Cook County Assessor is required by law to identify and assign fair market values to all properties in Cook County. The County Assessor does not set taxes, mail bills or collect taxes. The  County Assessor is responsible only for estimating the value of your property, which determines your assessed valuation.
