The Cook County Assessor mailed reassessment notices to each property owner in Wheeling Township.  The 30 day period for filing an appeal with the Cook County Assessor for the proposed assessed value was from July 11th through August 11, 2016.  If you file an appeal with the Cook County Assessor, you will get a response directly from their office through the mail.  If you receive a reduction in the proposed assessed value, it will be reflected on the second installment tax bill payable in 2017.  

If you missed filing an appeal with the Cook County Assessor and feel that your assessed value is too high, you will have an opportunity to file an appeal with the Cook County Board of Review.  We do not have the filing dates yet for Wheeling Township.  You can pre-file on their website @www.cookcountyboardofreview.com or check their website periodically to determine the opening and closing dates for filing an appeal.  The Cook County Assessor must complete their appeal process before the Board of Review can open for Wheeling Township.

If you need help finding comparables, email taxpayerassistance@wheelingtownship.com.  It is best to wait until we are open for appeals with the Board of Review as the figures might change.

Please Provide:

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

 We will e-mail comparables as soon as possible. If you visit our office or call during this period, please make sure you have a recent tax bill with your property index number ready.

 You can also call or visit the Cook County Assessor's office in Skokie located in the Cook County Circuit Courthouse, 5600 W. Old Orchard Rd., Rm 149. Phone #: 847-470-7237 

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.

Although the Board of Review still maintains a county office in the Rolling Meadows Circuit Courthouse, the Cook County Assessor does not.  It is permanently closed.


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.

Eligibility for Senior Citizen Exemptions (Born in 1950 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 $400 or more annually on the property tax bill. 
  2. Senior Freeze may provide some seniors with additional savings if the combined income of all occupants in a senior's household is less than $55,000 (for income tax year 2014), and if the senior has been an owner-occupant of the house since January 1, 2014.

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 1950 and turned sixty-five in 2015 would not have received senior application forms when the senior renewal forms were mailed.  A first-time applicant must complete the 2015 Homeowner/Senior Exemption application or the 2015 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 1951 and will turn 65 in 2016 will be eligible for the senior exemptions in 2017 when Cook County property owners pay on property taxes for 2016.  These forms will not be available on-line until mid January 2017.

Township Assessors do not assess property in Cook County.  The thirty Cook County Township Assessors including Wheeling Township are not funded or controlled by the County Assessor.  Assessment levels for all property are set by the Cook County Assessor.  Your 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.
