The Illinois Certificate of Mailing Garnishment (Non-Wage) is a document issued by the Illinois Department of Revenue which certifies that a garnishment notice was mailed to an individual or business. It is used to document the time and date when the garnishee was notified of the garnishment. This document is required when a garnishment is issued against a non-wage source, such as a bank account, property, or income from a business. There are two types of Illinois Certificate of Mailing Garnishment (Non-Wage): the Certificate of Mailing for a Bank Levy and the Certificate of Mailing for a Property Levy. Both forms must be completed by the issuing office and mailed to the garnishee along with the garnishment notice.
