An assessment complaint is based on the assessed value of your property – not a complaint about the amount of your taxes.
Property is assessed based on fair market value. Fair market value is the price you would be willing to accept for selling your property. To file a complaint you must fill out a complaint form that is available in the Supervisor of Assessments office or on this page.
Reasons to file a complaint are:
- Incorrect information on the property record card
- The condition of property
- The fair market value is higher than your opinion of market value
- Inequity based on the assessments of similar properties
Evidence may include, but is not limited to the following:
- Proof of a recent sale
- A list of comparable properties
- Recent photos showing condition of property
- A professional appraisal less than one year old
- Any other information you feel will help you prove your claim
The Board of Review will consider an appraisal, but an appraisal is not the only consideration of value, it is just the appraiser’s opinion of the value.
Board of Review Decision
The Board of Review will consider all evidence you provide them and may view your property. You will then receive a tentative decision in the mail. If you agree with their decision, you do not need to do anything.
If you disagree with their decision, you must call within the time listed on the decision to ask for a final hearing. At the final hearing with the Board of Review you will present your case in person. You will be notified by mail of their final decision.
Property Tax Appeal Board
If you disagree with the final Board of Review decision, you have 30 days from the date of the Board of Review mailing to appeal to the Illinois Property Tax Appeal Board (PTAB). Forms will be available in the Supervisor of Assessments office or on the Illinois Property Tax Appeal Board website.
