The Cook County Treasurer will mail the 2nd installment tax bills on or about July 1st. To avoid late fees, the bills must be paid by August 1, 2017. If you received a reduction in your assessed value from the Cook County Assessor or the Board of Review, it will be reflected on this bill.

 Check your bill carefully to make sure any exemptions you are entitled to were deducted.


Property owners may file an appeal to contest their total assessed value with the Cook County Assessor for the 2017 taxes payable in 2018.  The tentative 30 day period for filing an appeal is July 7th through August 7th, 2017.  You can file online at www.cookcountyassessor.com when the Cook County Assessor opens our township.  Check the county website for the exact dates to file.  If you qualify for the senior freeze, you do not need to appeal.

If you file a hard copy appeal at the township office, please drop off a few days before the appeal deadline, so we can deliver it to the Cook County Assessor on time. If you plan on dropping it off with us, call to see when our deadline is.  Check the Cook County website for the exact dates to file with the county.

The township office will be extremely busy during this period as it will overlap the mailing of the 2016 second installment tax bills. If you call or visit our office during this time, we ask that you have a tax bill with your property index number ready.

 Please note that you cannot appeal the current tax bill.

If successful in getting a reduction of your assessed value, the effect will appear on the second installment tax bills paid in the calendar year 2018.  

If you need help finding comparables, email us @ taxpayerassistance@wheelingtownship.com.  

Please Provide:

  • E-mail address
  • Property index # (found on your tax bill)
  • Address and phone number

 We will e-mail comparables and instructions for appealing as soon as possible. You can also call or visit the county office in Skokie located in the Cook County Circuit Courthouse at: 5600 W. Old Orchard Rd., Rm 149. Phone #: 847-470-7237. You may also drop off your appeal at their office. 

The Rolling Meadows Cook County Assessor's office in the Circuit Courthouse is permanently closed.

 After the 30 day filing period is over, taxpayers will have a second change to appeal later in the year with the Cook County Board of Review. The Board of Review still maintains a county office in the Rolling Meadows Circuit Courthouse. You do not have to file with the Cook County Assessor first to file an appeal with the Board of Review. Check the Board of Review website periodically to follow the filing dates for our township www.cookcountyboardofreview.com.


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.  The renewal forms should have been returned to the Cook County Assessor's office by February 3, 2017.

At this point you must file a Certificate of Error for the Senior Exemption if you did not file the renewal. You will need to attach a copy of your tax bill and a driver's license or a state I.D., with the property address issued prior to January 1 of the tax year. If you filed after the deadline, your exemptions will not show on your tax bill.  You should receive a revised bill shortly. 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 1951 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 5,000.  That can equate into a savings of $500 or more annually on the property tax bill. 
  3. 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 $55,000 (for income tax year 2015), and if the senior has been an owner-occupant of the house since January 1, 2015.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 1951 and turned sixty-five in 2016 would not have received senior application forms when the senior renewal forms were mailed.  A first-time applicant must complete the 2016 Homeowner/Senior Exemption application or the 2016 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.  At this point, a Certificate of Error for Senior Exemption is required.

 Homeowners who were born in 1952 and will turn 65 in 2017 will be eligible for the senior exemptions in 2018 when Cook County property owners pay property taxes for 2017.  These forms will not be available until mid January 2018.

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.
