What Are Property Taxes?

Property taxes are defined as a tax, generally based on the value of property, authorized by state law and used to fund services provided by local governments. In Champaign County, the majority of property taxes go to fund school districts but also fund many local services such as parks, libraries, emergency protection, police, and county and municipal services.

What Happens If I Don't Pay My Property Taxes?

Tax buyers can purchase the delinquent taxes at the annual tax sale. This adds interest and fees to the outstanding delinquent property tax bill owed by the property owner. If the property taxes continue to go unpaid, it can result in a loss of the real estate deed or title for the mobile home.

How Do I Pay Delinquent Property Taxes?

Delinquent taxes can only be paid in full and by cashier's check, money order, or cash. To pay a delinquent property tax bill, make an appointment with the Taxes Division by calling us at 217/384-3722 or email We will provide an exact amount due when you make the appointment. Cashier checks and money orders should be payable to Champaign County Clerk and must be in the exact amount that is due.

Why Are My Delinquent Property Taxes Increasing?

Interest and fees are added to delinquent property tax bills. To stop the increase, pay the delinquent property tax bill in full as soon as you can.

I Need To Make Changes To My Mobile Home Registration

According to Illinois Statute 35 ILCS 515/4, all mobile homes must be registered with the County Clerk of the county they reside in. It is a Class A misdemeanor if a mobile home is not registered. All registrations must be completed within 10 days of moving into the mobile home.

To make any update to a Mobile Home Registration, ALL taxes must be paid.  You can fill out the form (linked in the right menu) and mail it or drop it off at the Clerk's Office.  You can also come into our office to update the registration as well.  If you need the form printed and mailed to you, please contact us at or 217/384-3722. 

Registration and updating the title are two different things.

To update a mobile home title all taxes must be paid.  You will go to the Treasurer’s Office to obtain a Certificate of Taxes Paid.  To receive this Certificate, you are required to have the title in hand.  If you do not have the title the Certificate will not be issued.  Once you receive the Certificate you will take the title and Certificate of Taxes Paid to the Department of Motor Vehicles (DMV).  The Clerk’s Office receives a copy of this certificate, so unless you are destroying or moving the mobile home, a registration form is not required.
