Assessor's Office


The Appeal Process

If you have a problem with your assessment, please feel free to contact the Naperville Township Assessor's Office. We will be glad to sit down and listen to your concerns about your property assessment.

The following information may help you prepare for the meeting, and will help us understand the situation better:

Comparable sales and assessments information can be gathered by researching the public records available on our website. If you need assistance, please contact our office.

Complaints may be based on the following objections:

Higher taxes are a legitimate complaint, however they DO NOT have a bearing on the Assessor's opinion of value.

Taxes are based on the needs of the taxing bodies in your jurisdiction. Even if your assessment stays the same, taxes may still increase. Complaints of this nature should be taken up with the officials who determine budgets in the various bodies.

We always recommend contacting the Assessor's Office first if you have any issue with your assessment. You may discuss your assessment with the Assessor at any time throughout the year. After meeting with Assessor, and if you are still not satisfied with the Assessor's decision, you may file an appeal with the DuPage County Board of Review (BOR) within 30 days after the publication of the assessment list in the Naperville Sun. The publishing date varies each year, and can range from early Spring to November 15th. Please call the Assessor's Office for an estimate of the publishing date. At the BOR hearing, you will be required to present your information to a three member panel. After receiving notice of the Board of Review's decision, you have thirty days to appeal to the State Property Tax Appeal Board.

Remember, most of the misunderstanding on your assessment may be answered by a simple call or by furnishing supporting data to your local Township Assessor.
