I am an employer. Am I required to submit copies of my employees' Forms W-2 or 1099 to the Illinois Department of Revenue?

Yes. Forms W-2, W-2c, and W-2G are required to be electronically filed with Illinois. Forms 1099, apart from Form 1099-K, are not included in the electronic filing mandate nor are they required to be submitted to Illinois.  Form 1099-K is required to be submitted electronically under certain circumstances.

For information about Illinois' Form W-2 and 1099 filing requirements (including Form W-2c, W-2G, and Forms 1099), see Publication 110, Forms W-2, W-2c, W-2G, and 1099 Filing and Storage Requirements for Employers and Payers.

Note: If you are unable to file electronically, you may request a waiver by contacting Taxpayer Assistance at 1 800 732-8866 or 1 217 782-3336 to request Form IL-900-EW, Waiver Form.

If you have additional inquiries, you may submit them on the Questions, Comments, or Requests form.
