Informational Guide

In addition to the information below, we have included a printer friendly high level informational overview of the changes.  We will be updating this document on a periodic basis to reflect the new process.  Please continue to review this website and the informational guide.

UI 3/40 wage report

The second quarter of 2017 “Employer’s Quarterly Contribution and Wage Report” UI 3/40 will be the last pre-printed quarterly report mailed to your business. This move is due to increased security concerns to protect the employee names and Social Security Numbers of Illinois employers.

  • Employers with fewer than 25 employees can still file paper quarterly UI-3/40s. The online form has been improved to allow you to fill out the form online, save it and print it. Download the UI3/40 here.
  • Employers with any employee size will have the option to file quarterly UI-3/40 wage reports and make payments through their MyTax Illinois account at
