Submitting files

Illinois accepts electronic filing for Prior Year Filing.
The state accepts W-2C electronic filing for Corrections.
At this time the e-file add-on does not support the MyTax Illinois Login Version of the csv formatted file. The Non-Login Bulk Upload is supported. Please refer to: https://tax.illinois.gov/content/dam/soi/en/web/tax/programs/electronicservices/documents/idr-996.pdf

Before you process a file, if your W-2s contain Medical Savings Account Information, MSA, enter the information on any line in box 14 in the following format: MSA 1234.56.

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.
