Dear Citizens:


If you have recently purchased a home in our township, and your purchase price is less than the current assessed value, please call our office so we may review your assessment at no charge. 

2019 is a quadrennial reassessment year. This means that by state statute, every parcel will receive a revised assessment notice in August of 2019, regardless of if the value of your property has changed or not. 

In DuPage Township, we look at all subdivisions every year to determine what is happening with the market; whether it is going up, down or staying the same.  Appropriate factors are applied to the subdivisions if needed, and notices are sent. During the years between the quadrennials, if there is no change in value, the parcels do not receive notices.  If only a township multiplier is applied by the county, no notices are sent, however, the multipliers are published in a local paper chosen by the county, as this is more cost effective for the taxpayers.

Quadrennial notice assessed values are used for the 2019 tax bill, which is payable in 2020. The notice is not a bill! Remember these values are as of January 1, 2019.  Please keep in mind the following:

  • Assessed value is 1/3 of market value (.3333).
  • Assessments are based on 3 years of VALID sales prior to the assessment date.  2019 values are based on sales from 2018, 2017, and 2016 – not current market.
  • Once the notices are sent, there is a 30-day period in which you can formally file an appeal at the Board of Review in Will County. 
  • At this time, you may file an Assessment Review Inquiry located on this website if you do not agree with your assessment.  Please note the deadline for doing so is July 31, 2019.
  •  Exemptions will NOT appear on this notice.  This includes senior freeze amounts.
  •  You DO NOT need to hire a lawyer, a tax consultant, or pay a fee to have your assessment reviewed. This is what we do and we are here to help you understand the process. 
  • If the property is a recent sale, please contact our office before filing.  We may be able to avoid the appeal process. 
  • If your argument is equity. Find three comparables within your subdivision, of the same or similar style and size.  Our office does not do the research for you.
  • If you believe there is an error in what you are being assessed for, please contact us prior to filing. Check our website with your PIN and make sure everything is accurate.  Please know that we are constantly updating our system, and we will be happy to review your property information with you.

Formal appeals are now submitted electronically. To file a formal appeal with Will County Board of Review, please visit their appeal portal at borappeals.willcountysoa.com.  DuPage Township does not have Board of Review appeal forms in our office. The deadline to file an appeal is Monday, September 9, 2019.
