What to do

  1. Run the free check above. It compares your assessed value per square foot with similar homes in your assessment neighborhood.
  2. 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.
  3. 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.
  4. Leave an email on the result page and we'll remind you a week and three days before the deadline.
