2021 Board of Review Information

The 2021 Board of Review will begin taking appeals after the publication of notices beginning August 11, 2021.

Our office highly recommends submitting your appeal electronically through our online portal at borappeals.willcountysoa.com. Those who would like to submit an appeal will have until September 13, 2021. After this deadline has passed, no appeal submissions will be considered.

For more information regarding the Will County Illinois Board of Review Rules and Procedures, Appeal Forms available for download, and Quick-Start Guides to aid in the submission process, please visit borappeals.willcountysoa.com on or after August 11, 2021.

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.
  • Please wear a mask, regardless of vaccination status, upon entering the Supervisor of Assessments Office and throughout your appeal hearing.



Exemption Renewals

Our office received notice on Friday, July 23, that Governor Pritzker signed HB-3289.
This means if you received a renewable exemption in 2020 it will be carried over for 2021.

Any new applicants still need to apply for their desired exemption, otherwise all received and processed exemptions in 2020 will carry over to the 2021 levy year.

Please call our office with any questions regarding your exemptions!

The Will County Supervisor of Assessments Office governs every aspect of the assessment process, acting as a central resource for its county's residents. We believe that our primary responsibility is to the taxpayers, and we are committed to ensure that all county residents receive fair and equitable assessments. We are also dedicated to making sure that eligible taxpayers are receiving the beneficial exemptions they are entitled to; all with the utmost courteous and respectful service. The Supervisor of Assessments Office is also committed to promoting taxpayers education and involvement in the assessment process through open discussion forums, informational meetings, and community outreach endeavors. The valuations for 2020 are for the assessment year of 2020, payable in 2021. This means that the assessment you are looking at is for this year's upcoming tax bill. The tax rates for this year have not been established yet. The Supervisor of Assessments does not establish tax rates (tax rates are established by local taxing bodies). However, you can search our website for the most current assessments using our Property Search Portal, where you can conduct property searches by PIN, property address, and more.

For an explanation on tax rates, please visit the Will County Clerk's Office.

For any additional tax bill questions visit the Will County Treasurer's Office.
