What happens after I file an appeal?

After submission, your appeal enters a formal review process.

Review steps:

  • Evidence is evaluated by analysts

  • Market data and comparable properties are reviewed

  • A determination is issued

Possible outcomes:

  • Assessment reduced

  • No change

  • Rare increase if errors are discovered

Decision notices are published online by the Assessor or Board of Review.

If denied at one level, you may continue to:

  • Cook County Board of Review

  • Illinois Property Tax Appeal Board at ptax.illinois.gov

  • Circuit Court

Cook County Tax Appeals monitors appeal status and manages the process through each stag
