2024 Assessment

The 2023 assessment cycle will be completed with the mailing of the tax bills in early May of 2024. As a result, we have already begun our assessment process for the assessment year of 2024, with bills payable in 2025. We hope to publish our values sometime in September 2024, although no final date has been set.

Your 2023 assessment information and Property Record Card (PRC) are available on our website for reference, and will be updated with the 2024 values once we publish again later this year.

If you have concerns about your potential 2024 value, please contact our office and we would be happy to discuss your property.

The Appeal Process

If you disagree 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:

• Recent purchase contracts, listings, and closing statements of your property
• Sales of similar homes in your neighborhood
• Assessments of similar homes in the area
• Recent appraisal of your property
• Photographs of your home and comparable properties in your neighborhood

Comparable sales and assessments information can be gathered by researching the public records available on our website.

Parcel Search - Locate your property
Residential Sales Search - Review comparable residential sales data
Commercial Sales Search - Review comparable commercial sales data

Complaints may be based on the following objections:

• Incorrect data - Information about your property is incorrectly reported on the Assessor's property record card. Errors in square footage or numbers of bathrooms in the home are some examples.
• Market Value - Based on comparable sales in the area, your house would sell for less than the Assessor's opinion of value.
• Inequity - The market value of your property is accurate, but similar properties are assessed for less.

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 and/or the staff at any time throughout the year. After discussing your property, and if you are still not satisfied with the Assessor's decision, you may file a formal appeal with the DuPage County Board of Review (BOR) within thirty (30) days after the publication of the assessment list. 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 (30) 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.
