I am an employer. Can I submit my employees' Forms W-2, W-2c, W-2G, and 1099 to IDOR electronically?

Forms W-2, W-2c, and W-2G are required to be electronically filed with Illinois. Forms 1099 are not included in the electronic filing mandate or required to be submitted to Illinois, unless we request them. Payers who issue Forms 1099, which report Illinois income tax withheld, may voluntarily file these forms electronically through the Illinois FIRE Electronic Transmittal Program or through MyTax Illinois.

Electronic Filing Methods:

  • One form at a time filing method - MyTax Illinois, our online account filing and management program, may be used to submit Forms W-2, W-2c, W-2G, 1099-R, and 1099- MISC. If you do not already have a MyTax Illinois withholding tax account, you must first create one to be able to file using this method. Once your MyTax Account is set up, enter the W-2, W-2c, W-2G, 1099-R, or 1099-MISC information on MyTax Illinois for each form, one form at a time. For detailed information, go to our website at mytax.illinois.gov. Note: You cannot bulk file through MyTax Illinois.
  • Electronic bulk filing methods - (These methods are separate from MyTax Illinois method) If you have not already registered with us for W-2 electronic transmission, you must register to obtain a Transmitter’s logon ID (ETIN) and receive test and production passwords. If you have already registered for W-2 electronic transmission, you do not have to register again for W-2G and 1099 electronic transmission. You may use the same ETIN and passwords.
    • Forms W-2 and W-2c Electronic Transmission Program - To electronically file Forms W-2 and W-2c using this method, the file must be developed following the Social Security Administration’s Specifications for Filing Forms W-2 Electronically, and the additional Illinois requirements in our Form W-2 and W-2c Electronic Transmission Guide.
    • The W-2G and 1099 Illinois FIRE Electronic Transmission Program - To electronically file Forms W-2G and all types of 1099s using this method, the file must be developed following the Internal Revenue Service’s (IRS) Filing Information Returns Electronically (FIRE) format, and the additional requirements in the Illinois FIRE Electronic Transmission Guide.

For detailed information and updates, refer to Publication 110, W-2, W-2G, and 1099 Filing and Storage Requirements for Employers and Payers, or the W-2 and 1099 Electronic Filing Program page on our website, tax.illinois.gov.
