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 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 2019 are for the assessment year of 2019, payable in 2020.  This means, 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, however, you can search our site for the most current assessments under our PIN Search or Address Search
