The Sugar Grove Township Assessment Office is continuously updating Property Record Cards.  You may receive a knock on your door from our Assessor and or Field Deputy to update pictures and property information of all Township properties.  This does not necessarily mean that your assessment will be increased.  Per Statute (35 ILCS 200/9-155) every property should be looked at every four years. If you have any questions please feel free to contact the Sugar Grove Assessment Office at 630-466-5255.



The 2022 equalized assessments are complete and can be viewed on our web site.  The assessed values listed on this site have been equalized by the Kane County Supervisor of Assessments with a factor of 1.0508 for Sugar Grove Township. (35 ILCS 200/9-205)

Assessments are determined by a property's value as of January 1, 2022.  The market "today" is not reflected until the 2023 assessment year.  Therefore, any sales or appraisals dated after January 1, 2022 cannot be considered until the 2023 assessment year.  Illinois State Statute (35 ILCS 200/1-55) mandates the use of sales studies for the three most recent years preceding the assessment year to obtain the fair cash value for a current assessment year.  The 2022 assessment considers sales from 2021, 2020 and 2019.

Please be advised that as a taxpayer in Sugar Grove Township it is NOT necessary to hire legal counsel or any type of tax appeal firm representative when seeking an assessment reduction.

If you would like your property assessment reviewed, please contact our office prior to filing a formal assessment appeal to the Kane County Board of Review.  Please submit three comparable properties
located in the same neighborhood either based on equity or recent sales (Request for Assessment Review form available
HERE). If your concern is based on recent sales please include three comparable properties that have sold within the last three years, this excludes a current year's sale. ***Please note: include sales other than "short sales" or "foreclosures".  The comparable properties must be located in the same neighborhood, same style and the building square footage as close to 200 square feet more or less than your home.  Other items that may affect value are location, amenities,
construction quality and condition.  There could be more factors that affect a property's value and will be determined as a property is individually analyzed.

Upon completion of your assessment review and an agreement of value has not been reached you may file a formal appeal with the Kane County Supervisor of Assessments.  The web address is  There you'll find instructions and forms for property assessment appeals.

 *** If your goal is to decrease your tax burden, having your assessment reviewed and lowered is only a small part of the process.  Decreasing your taxes is achieved by decreasing the taxing

The Assessor is responsible for assessing property at one-third of fair cash value with the exception of farmland, railroad or coal properties which are properties valued by the State of Illinois Department of Revenue. It is always encouraged and highly recommended to discuss your property assessment first and foremost with your local Assessor before ever filing with the Board of Review.

The Assessor is the only elected official with exception to your States’ Attorney that requires a formal education and 2-yr certification along with yearly continuing education and is working directly for you.
