The 2015 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 1.0325 for Batavia Township.

Assessments are based on what your property is valued at as of January 1, 2015. The market "today" is not reflected until the 2016 assessment year. Therefore, any sales or appraisals dated after January 1, 2015 cannot be considered until the 2016 assessment year. Per Illinois State Statutes we are mandated to use the three previous years of sales to obtain the fair cash value for a current assessment year. So for the 2015 assessment year we must use sales from 2012, 2013 and 2014.

If you wish to have your assessment reviewed further please contact our office prior to filing an appeal. We request that you submit three comparable properties and/or sales within your neighborhood. Comparable properties are considered to be located in your neighborhood, approximately the same square footage (within 200 sqft) and the same style as your home. If you submit sales data, please be sure to include sales other than just foreclosed or short sales that occurred within the three year period.

Upon completion of your assessment review, if you still do not agree with our value, 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 levies. To do this, contact the taxing districts located on the front of your tax bill.   ***
