Downers Grove Township’s annual multiplier and changed assessments are published in our local newspapers in September or October. An exact date cannot be set due to the volume of assessments having to be reviewed in any particular year. The assessments are also displayed on our website, see Parcel Search.
Prior to filing an assessment appeal contact the Assessor’s Office; many times problems can be solved at the Township and save you a trip to Wheaton. However, once the publication occurs, a property owner or agent has 30 days to file an appeal with the DuPage County Board of Review. Appeals must be postmarked on or before the deadline. Based on your preference, the Board of Review will schedule a hearing or an assessment review without you having to appear. You must submit your evidence to the Board of Review along with your Appeal form.
Please note: This is not an appeal or protest of your tax bill; it is about the assessed value of your property.
Appeal forms can be downloaded from the Supervisor of Assessments website. Once at the County website you will see a list on the left; at the bottom you will see Forms, Documents and Links, this will direct you to the Board of Review Appeal forms.
Please read the Appeal form carefully. Fill in the necessary information, submit any additional evidence, and mail directly to the Board of Review. This will assist the Board of Review in making a decision regarding the assessed value of your property.
If you have opted to have a hearing, the Board of Review will notify you by mail of the date and time. Hearings normally take place at 421 North County Farm Road, Wheaton, at the Board of Review/Supervisor of Assessments offices on the first floor. Due to the volume of hearings, rescheduling is not possible.
A Deputy Assessor from Downers Grove Township will also be present at the hearing. The Deputy will bring your Property Record Card file and evidence to support the assessment. Hearings are scheduled in 15 to 20 minute increments. Due to the volume of hearings and the time allotted, it is important to be concise and prepared to present your evidence.
Once heard, the Board of Review will determine the proper assessment of your property and will notify all parties by mail in March.
After receiving the Board of Review decision, if a property owner remains dissatisfied, you have 30 days to file an Appeal with the State of Illinois Property Tax Appeal Board. The forms and procedures are available on the PTAB website. Please note, due to cut backs at the State level the PTAB is experiencing a huge backlog of hearing case files. Your hearing may not take place for 2-3 years. During that time you must pay your property tax.
Normally residential appeals fall into two categories, a market value complaint or a uniformity problem. If you recently sold or purchased the property you are appealing please notify the Assessor’s Office first. We will review the sale transaction and make any necessary adjustments to the assessment.
If there has been no sale of your property then you would want to gather evidence of recent sales of similar properties in your area and fill in the Residential Comparison Grid. To find sale information, a property owner can utilize the Assessor’s Parcel Search, contact the MLS or a realtor for sales information or get an appraisal of the property.
If you think the assessed value of your property is too high compared to other similar properties, list these comparable properties on the Residential Comparison Grid. Most of the information needed for the Grid can be obtained at our website.
The type of commercial-industrial property is important when submitting evidence for an appeal. If the property is income-producing, such as an apartment building, strip mall, office building, etc. an income and expense statement or vacancy statement should be submitted.
In some cases, it may be necessary to get an appraisal of the property. Forms for a Commercial-Industrial Appeal can be found at the Supervisor of Assessments website.
