Filing an Assessment Complaint

Rules of the Board of Review Guidelines for Assessment Complaints

Before you submit a complaint, please review the Guidelines for Assessment Complaints (PDF). It does not replace the Rules of the Board of Review, but it does help provide practice tips and explanations of the appeal process, including:

  • Examples of supporting evidence
  • Farm guidelines
  • Hearings by the Board of Review
  • State of Illinois property tax assessment law

The Board of Review wants to help you be well prepared and informed. These guidelines are intended to help you understand the process and to be successful in your presentation.

Current Assessment Details

The current assessment is based on the past three years' market value prior to January 1 of the assessment year, as required by Illinois law. An equalization factor (multiplier) will be applied where the three-year market value is either more or less than the assessed value to bring the statutory assessment to 33.33%.
