Will County Supervisor of Assessments
Board of Review - Assessment Appeals Process

The time window to file an appeal with the Will County Board of Review is August 7, 2024 through September 9, 2024.

The Board of Review suggests that you speak to your township assessor with any specific questions about your assessed value change. The Board of Review appeal process begins in August for each assessment year and appeal forms can be obtained at the Board of Review office, mail, or by download:

Will County Board of Review
Will County Office Building
302 N. Chicago Street, 2nd Floor
Joliet, IL 60432
Phone: (815) 740-4661

The owner for each parcel of property must file a separate appeal unless the parcels are contiguous. Contiguous parcels may be on the same appeal provided they are of the same land use. The property identification number (PIN) must be included along with the address of each parcel. The appeal form must be signed, have the mailing address of the owner, and a daytime telephone number where the appellant may be reached.

ATTENTION: Pursuant to Section 7 (e) of the Open Meetings Act, the Will County Board of Review requires that you check the Board of Review Portal 48 hours prior to your scheduled hearing to ensure that the hearing will be a live hearing. In the event that the Board chairperson determines that an in-person hearing is not practical, prudent, or unfeasible due to an unforeseen circumstance, the Board will have a non-interactive hearing in place of your scheduled hearing and the decision will be based on the weight of the evidence provided. If you do not have computer access, you must call the board office at 815/740-4648.  In the event that a live hearing is not feasible, you will have the ability to submit rebuttal to the township assessor and or intervenor evidence via electronic submission of a written brief. This must be submitted 48 hours prior to the non-interactive hearing.

Pursuant to Section 7(e) of the Open Meetings Act, in the event of a disaster Declaration, the Chairperson of the Board of Review reserves the right to determine whether an in-person meeting is not practical or prudent because of the disaster. In that event, the procedures outlined in the Open Meetings Act and that section of the act as amended shall be followed.

**Due to security changes in the Will County Office Building, all visitors are required to pass through a security check upon entrance of the building.**

  • Please arrive to the building at least 15 minutes prior to your scheduled hearing. This will allow you time to pass through security and arrive at your hearing in a timely manner.



The Board of Review shall base its decision on the documented evidence presented by the appellant and the township assessor and their testimony. The Board of Review uses three methods of valuation that are standard in most appraisal organizations. These are Cost, Market, and Income approaches to value. While the Board of Review does not expect the general public to know the finer points of the appraisal business, if they reasonable believe that their property is not being assessed properly, or that its value is too high, then some method of comparison should be used to prove their case.
