File a Written Complaint

Appealing an Assessment

Step 6:  File a Complaint With the Board of Review

All Illinois counties, have a local appeal board known as the Board of Review. Complaints must be filed in writing with the Board of Review in the county where the property is located within 30 days of the date of publication in your local paper. (important dates).  Appeal forms can be obtained from the York Township Assessor’s Office, the DuPage County Board of Review, or online by using the links shown below.  Please note that appeal forms cannot be faxed or emailed.  If you are using the online forms shown below, the form will need to be printed and mailed to the address listed at the top of the form.

The Board of Review offices are located at 421 N. County Farm Road, Wheaton, IL 60187. The Supervisor of Assessments serves as the Clerk of the Board of Review and can answer your questions when the Board is not in session.

The Board of Review has the power to raise or lower individual assessments on complaint. It may also adjust assessments on its own initiative. But no assessment can be raised until the taxpayer affected has been notified and given an opportunity for a hearing. It is important to remember that you will be appealing the assessment on your property upon which your tax bill is based. The Board of Review does not have the authority to change a tax rate. After deliberating, the Board of Review must notify you in writing of its decision.
