The next opportunity to appeal the 2018 Property Tax Assessment will be with the Cook County Board of Review. We are available to provide information and assistance. If you would like comparables for an online appeal please email us at taxpayerassistance@wheelingtownship.com  and provide your PIN number (in subject line), name and address. These comparable properties can be used when filing at www.cookcountyboardofreview.com.

If you do not use the internet you may file a hard copy in our office, which will be mailed to the Cook County Board of Review.

If the Assessed Value is reduced, the lowered amount would be reflected on the 2nd installment bill issued in 2019.

Please note: Cook County Board of Review and Assessor offices in Rolling Meadows Courthouse have been permanently closed.


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

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

The new 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 will be at least 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.


Under current law, SENIOR EXEMPTIONS MUST BE RENEWED EVERY YEAR. Anyone who received a senior exemption on their property in the past and still qualifies for the exemption must submit a renewal form each year. The Cook County Assessor's Office mails senior citizen renewal applications for senior citizen property tax exemptions in early January.  

If you file after the deadline, your exemptions will not show on your tax bill.  If you or your mortgage company pay the full amount, you will receive a refund, if you file a Certificate of Error.  Please note that the bill is still due on the original due date whether you receive the revised bill or not.  

Eligibility for Senior Citizen Exemptions (Born in 1953 or Earlier)

There are two senior citizen property tax exemptions:

  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 into a savings of $500 or more annually on the property tax bill. 

EVEN IF YOU DO NOT QUALIFY FOR THE SENIOR FREEZE fill out the FRONT of the form to renew your senior exemption.

      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 2017), and if the senior has been an owner-occupant of the house since January 1, 2017. 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 changing 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.

Homeowners who were born in 1953 and turned sixty-five in 2018 do not receive senior application forms when the senior renewal forms are mailed.  A first-time applicant must complete the 2018 Homeowner/Senior Exemption application or the 2018 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 www.cookcountyassessor.com 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.  


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.


First installment tax bills will be mailed in February, due and payable in March. Please remember that the first installment is 55% of the previous year's bill; all exemptions are deducted on the 2nd installment which is usually sent in July, due in August.

The County does not forward tax bills. If you are away for the winter you can go online to the treasurer's website www.cookcountytreasurer.com and pay (no fee) from a checking account or print a duplicate bill and mail a check to the Treasurer.

Second installment bills are usually mailed in July and due in August.

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.
