Filing Your Appeal

First:


Check the date of written decision/notification from your county or township - This appeal must be filed within 30 days to be considered.

Your appeal form:

  • Must be completed in its entirety,
  • contain the basis of your appeal, and
  • provide evidence to substantiate your claim.

In general, residential appeals where a change of less than $100,000 in assessed value is sought can use comparable properties, (similar in age, construction, location and square footage) or an appraisal.
For commercial and industrial appeals, an appraisal is recommended.



Required:

  • 3 copies of your completed appeal form must be submitted to PTAB's Springfield Office along with:
  • 2 copies of your evidence (3 copies if the amount sought is more than $100,000)
  • 2 copies of your Board of Review's original final decision letter
  • Two copies of Board of Review's original final decision
  • For Cook County Only: In addition, if your appeal is based upon the date the Board of Review transmitted its decision to the county assessor, then you must also supply a hard copy of the date of transmittal. See Cook County Board of Review's website for this information.
  • County and Township information (Section II)
  • Property I.D. Number (Section 2a)
  • Board of Review assessments (contact your local assessment office for the correct amounts), and your claim for land, improvement, and the total (Section 2c)

  • Three copies of all evidence must be submitted with your appeal, if the change in assessment you request is $100,000 or more.
