 The Will County Supervisor of Assessments office governs every aspect of the assessment process, acting as a central resource for county residents.  We believe 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 eligible taxpayers are receiving beneficial exemption 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 2016 are for the assessment year of 2016, payable in 2017.  This means, the assessment you are looking at is for next year's tax bill.  The rates for the next year have not been established yet.  The Supervisor of Assessments does not establish tax rates, though, you can search our site for your 2016 assessment under our PIN Search or Address Search.

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.
