The Assessor is responsible for assessing property at one-third of fair cash value with the exception of farmland, railroad or coal properties which are properties valued by the State of Illinois Department of Revenue. It is always encouraged and highly recommended to discuss your property assessment first and foremost with your local Assessor before ever filing with the Board of Review.

The Assessor is the only elected official with exception to your States’ Attorney that requires a formal education and 2-yr certification along with yearly continuing education and is working directly for you.
