Transmitters of information returns are now able to submit EFW2, EFW2C, and FIRE formatted files through MyTax Illinois without creating an account. This new, non-login feature supports submission from any internet browser and does not require the download of a tool for transmission.

This new submission method provides real-time review and error feedback rather than a back-and-forth acknowledgment process that is typical of other transmission methods. Only error-free files will be accepted and confirmed.

1. Go to https://mytax.illinois.gov on the landing page

2. Scroll to the bottom of the page to the box labeled “Non-Login Return or Report” and select “Submit Bulk W2/1099 File”. This opens an active request in MyTax Illinois.

3. Provide the required information, follow the on-screen instructions, and navigation to complete your submission.
