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%.
