How do I request additional copies of blank paper ST-556 and ST-556-LSE returns?

After activating your account, you can utilize MyTax Illinois to obtain and print blank ST-556 or ST-556-LSE returns pre-filled with certain information for each of your business locations. You can also contact the Illinois Department of Revenue’s (IDOR) Central Registration Division at 217 785-3707 to request additional blank paper returns for each of your business locations.

Note: Do not photocopy or otherwise duplicate a paper Form ST-556 or ST-556-LSE if you need additional returns. Each return is printed with a unique transaction number that IDOR uses for identification purposes. Filing a photocopied return may cause delays in processing the return and may result in IDOR assessing penalties and interest.

You may access additional information by searching the entire Illinois Department of Revenue website.

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