 ** Please note that if you have received your property tax bill,

The mission of the Township Assessor's office is to fairly and equitably assess the real property in the jurisdiction according to state statute.   

The Assessor does not decide your property tax bill, which involves a completely different process. Your property is located in several different taxing districts. Not everyone has the same taxing districts, and your districts could be different from your neighbors'. Usually, the most expensive district will be for your local schools. Some people will have two school districts, one for the primary schools and one for the high schools. Each taxing district gets to ask for the amount of money it needs for the next year. In general, if they want more money than the previous year, they are limited to the rate of inflation, but there are some exceptions. When all of your taxing districts decide how much money they need, the County Clerk divides it among the property owners in your district.

Please continue to call our office if you have any questions about your assessment.  My staff will be glad to discuss them with you.  You may reach us at 630.466.5255 from 8:00 a.m. to 4:00 p.m. Monday - Friday.

 Thank you,

Curt John Karas, Assessor

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.
