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 2023 are for the assessment year of 2023, payable in 2024. 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.
