Record Layout for Filing New Hire Reports on Magnetic Media

The directory will list all persons hired for full-time, part-time or temporary jobs. The purpose of the directory is to help child support officials track down absent parents. In addition, the information provided through New Hire Reporting will help reduce fraud and abuse in Unemployment Insurance and Welfare programs.

Employers are being offered a range of options for reporting the necessary information. In this case you have chosen to report magnetically. This guide has been designed to help you meet the reporting requirements of this law.

It is designed to aid employers who wish to create a file using either the American Standard Code for Information Interchange (ASCII) or the Extended Binary Coded Decimal Interchange Code (EBCDIC) in the unpacked mode.

The Illinois Department of Employment Security (IDES) will be using the format that resembles the Federal guidelines in order to offer uniformity in reporting new hires. This file includes the information included on the Federal W-4 form.

This format is for "New Hires" only and not to be confused with the Quarterly UI3/40 file format.

Sources of Help: If you have technical questions regarding the file format, call the IDES Magnetic Media Unit.

If you have any general questions regarding new hire reporting, call the IDES New Hire toll free hotline.
