What happens if my appeal is denied?

A denial isn't the end. The Board of Review is independent of the Assessor, and you can file there whether or not the Assessor reduced your assessment. After the Board decides, you can go to the state Property Tax Appeal Board (PTAB) or, in some cases, file a tax objection in the Circuit Court.

For the full picture, see our guide to the Illinois Property Tax Appeal Board.
