Reasons for an Appeal
You have a legitimate reason to appeal your property tax assessment if you can prove any of the following:
1. The assessed value of your property is higher than the property’s actual market value. (As determined by a recent sale or appraisal.)
2. The assessment of your property is based on inaccurate information, such as incorrect dimensions for a building or lot.
3. The assessment of your property is higher than those of similar surrounding properties.
Eight Steps to Appeal an Assessment
There are eight steps you can follow to appeal your property assessment.
Step 1: Determine the Fair Market Value of Your Property
There are several methods you can use to determine the current value of your property. They are:
1. A professional appraiser may be hired. No Realtors comparative market analysis will be accepted.
2. You can determine the selling prices of several properties similar to yours using the previous three (3) years sales. You can also obtain the assessed value of those properties from their property record cards. Taxpayers have the right to inspect the property record cards and other assessment records of any property. You can also obtain copies of real estate transfer declarations or other evidence of the sale price of any property you are using to compare to your own.
3. If your home was recently built, you can determine its market value by calculating the actual cost of the structure and the purchase price of the land. Remember though that construction costs do not always equal value.
Step 2: Determine the Prevailing Level of Assessments
Illinois law requires the Supervisor of Assessments to release the average level of assessment in his or her township or county. The information is usually printed in your local newspaper or it can also be obtained from your township assessor’s office. For 2020, the York Township assessment level is 33.33.
Step 3: Determine the Assessed value of Your Property
A copy of the property record card showing the assessed value of your home is on file at your township assessor’s office. Remember that real estate in all Illinois counties, except Cook, is assessed at one-third of the actual market value. Therefore, the assessed value of your property should be close to one-third of its actual market value.
Step 4: Discuss Your Appraisal With an Assessor
Contacting your assessor early in the year and notifying him/her of an incorrect assessment may result in a correction without using the formal appeals process. Click here to submit an inquiry about your property.
Step 5: Determine the Basis for Your Complaint
After reviewing the information you have obtained, and after talking to your assessor, determine if there is still a basis for a formal complaint.
Step 6: File a Complaint With the Board of Review
Note: All forms require duplicates, therefore it is recommended to utilize the Acrobat- Editable forms and print duplicates. Please see Board of Review Rules for additional filing requirements.
