You must, however, continue to maintain employee W-2, W-2-G, and 1099R records for a period of three years from the due date or payment date, whichever is later. Each year the Department of Revenue requests these records from a sample group of employers. In the event the Department asks for your W-2 records, you must submit the information requested.
If you are requested to submit the W-2 information, the format used will be the same as that required by the Social Security Administration (MMREF format). The specific formats are outlined on their web site at: http://www.socialsecurity.gov/employer/pub.htm. Illinois requires you to submit the following records: RA (Submitter Record), RE (Employer Record), and the RS (State Record) in the MMREF format. When completing the information, please complete all fields listed in the formats, if possible.
