Employment Sign Up for Updates

What if I participated in a potentially abusive tax avoidance transaction?

If you participated in a reportable transaction, including a "listed transaction," during this tax year and were required to disclose that to the IRS, you are also required to disclose that information to Illinois. You must send us two copies of the form you used to disclose the transaction to the IRS. You must

  • attach one copy of your tax return and
  • mail a second copy to the
    Illinois Department of Revenue,
    P.O. Box 19029, Springfield, Illinois 62794-9029.

NOTE:  Employee benefit plans and other subtractions allowed on Form IL-1040, Lines 5 through 7, are not reportable transactions. For more information, contact the IRS or your tax professional.
