What to do
- Run the free check above. It compares your assessed value per square foot with similar homes in your assessment neighborhood.
- If yours looks high, get the evidence kit from the result page: the comps in the Board's format, recent sales, and a statement to paste into the form.
- File online at the office whose window is open. Filing is free at both. You type the complaint yourself; only you or an Illinois attorney can file for your home.
- Leave an email on the result page and we'll remind you a week and three days before the deadline.
