Dear Property Owners:

In Illinois the 2019 taxes are billed and collected in calendar year 2020.  I do not know the amounts of the individual bills, but I understand that the average tax rate is down 1.59% with the average bill up 2.21%  Remember this is an average, so it may not be your experience.  I have yet to meet with the "average".  

I am currently able to share some of the more interesting 2019 statistics.  The assessed property value in the County increased by 2.8% in 2019, the fifth year in a row for an increase. We will collect approximately $2,953,856,765.70 and we will distribute the funds to the appropriate taxing bodies.  New this year, the County adapted the Property Assessed Clean Energy (P.A.C.E) finance program for commercial properties.  This allows the property owners to repay their loans on their property tax bill.

There are three critical factors in determining what you pay.  The first is the assessed value of your property.  2019 was a “general assessment year.”   During this past year, the Township Assessors have determined the assessed value of each property based on 33.33% of the fair market value.  Any questions you may have concerning your assessed value, please contact your local assessor.  The telephone number is printed on your bill.

The second factor is exemptions you might be eligible to receive.  The most often missed is the senior exemption.  If you are 65 or older, check to make sure you have this exemption.  The number of senior exemptions this year is on 67,901 parcels.  There have been instances where taxpayers in their eighties have never benefited from this exemption.

The third factor is the tax rate.  It appears on the lower left side of the tax bill.  The rate is computed by the County Clerk using the assessed value and the amount of dollars levied by each taxing body.  Even though your tax rate may have decreased, the amount of taxes you owe can increase, if the taxing bodies ask for more money.

The Treasurer’s team is ready to assist you with your questions and payments.  Our website is available 24/7.  It has some interesting information about your property including:  Property Tax distributions; Assessment information regarding your property; a five (5) year Property Tax history as well as a Sale History or your property.  You can also print a duplicate bill. We urge you to consider using ePay for your payments.

If you have questions, please feel free to contact my office at 630-407-5900 or  It is a privilege to serve you.
