Submitting files

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. Select MyTaxIllinois 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.

Other ways to submit the file.

Register – Obtain your W-2 transmitter ID and test and production passwords. If you have registered in the past and have ETIN/Logon ID and passwords, those credentials are valid year to year. If you already have an existing ETIN/Logon ID and passwords for other Illinois programs, you may use those for the W-2 program as well. 

Note: You must be registered to file at least one business day before sending a file. Click here to register as a W-2/1099 Transmitter. 

  • Any employer or payroll provider that wants to transmit bulk W-2/W-2c/W-2G files must register to be able to transmit files directly to us electronically.

Logon to this secure online application using your web browser, enter your W-2 transmitter ID and password, browse for your W-2 file, and select the file to upload. This method does not require any software download or programming.

Acknowledgement: This user friendly web application tells whether the file was accepted or rejected and provides a list of any specific errors for a rejected file. Select the W-2 Transmission Acknowledgement link on the Electronic W-2 web page and log in using your ETIN and password you used to transmit the files. This retrieval method works for either transmission method. Important: For a rejected file, all errors must be corrected and the entire file must be retransmitted. If no acknowledgement is present within 24 hours after transmission time, please contact us for assistance at the number listed in contact
