Important Notice Regarding Assessments Learn More


The 2020 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 1.0367 for Batavia Township. (35 ILCS 200/9-205)

Assessments are determined by a property’s value as of January 1, 2020.  The market “today” is not reflected until the 2021 assessment year.  Therefore, any sales or appraisals dated after January 1, 2020 cannot be considered until the 2021 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 2020 assessment considers sales from 2017, 2018 and 2019.

Please note: Not every taxpayer will receive a notice.  Only those assessments changed by your Assessor will receive a notice.  

Assessments changed only by the county equalization factor will NOT receive a notice.
