The 2016 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 1.0233 for Batavia Township.

Assessments are based on what your property is valued at as of January 1, 2016.  The market "today" is not reflected until the 2017 assessment year.  Therefore, any sales or appraisals dated after January 1, 2016 cannot be considered until the 2017 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 2016 assessment year we must use sales from 2013, 2014 and 2015. 

Please be advised that as a tax payer of Batavia Township it is NOT necessary to hire legal counsel or any type of tax appeal firm to represent you when seeking an assessment reduction. 

If you disagree with your property assessment please contact our office prior to filing an assessment appeal.  Please submit three comparable properties located in your neighborhood either based on equity or overvaluation. If you are basing your concern on overvaluation please include three comparables that have sold within the last three years, this excludes a current years sale. ***Please note: to include sales other than "short sales" or "foreclosures". The comparable properties shall be located in the same neighborhood, same style, similar year built and the building square footage as close to 200 square feet above or below your home. Other items that may affect value are location, amenities, exterior; such as brick versus wood, 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, 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.  ***
