Returned Checks (including non-sufficient funds or NSFs, stop payments, etc.)
There is a $25 processing fee, in addition to any accrued statutory interest, for each check that is returned by the taxpayer's bank for any reason. Note the following:
- The returned-check processing fee cannot be submitted at a Chase Bank or through the Online Payment System.
- The returned-check processing fee must be submitted in person at the Treasurer's Office or by mail to:
Cook County Treasurer
118 North Clark Street, Room 112
Chicago, IL 60602
- Payment of the returned-check processing fee must be submitted separate from any subsequent payment of the taxes and any applicable late payment statutory interest. (The returned-check processing fee cannot be combined with the tax-and-penalty due on the same check.)
Written notices are mailed to the maker of any check returned by a bank for any reason. The original returned check is the property of the Cook County Treasurer's Office. Copies of the returned check are available only upon request in person at the Customer Service Department, Cook County Treasurer's Office, 118 North Clark Street, Room 112, Chicago, IL 60602.
