Supervisor of Assessments Office


  The Will County Supervisor of Assessments office in an effort to coordinate with the Centers for Disease Control and Prevention by minimizing contact to mitigate the spread of COVID-19 coronavirus is reducing its operation to phone and email contact only. We will continue to answer taxpayer calls and e-mails, but will not be open for in-person public business until further notice.

  All exemption renewal mailings and sign-up events have been delayed and will be rescheduled until after May 1st.

Local Township Assessor offices in Will County are following the same work plan as the county Supervisor of Assessments office.
