Report Identity Theft for a Business


If you think someone is using your business name or Employer Identification Number (EIN) to submit fraudulent tax returns or Forms W-2, complete and send to us Form 14039-B, Business Identity Theft Affidavit PDF. This form is for use by businesses, trusts, estates and tax-exempt organizations.

To prevent processing delays, make sure to send us all the requested documents and sign the Form 14039-B.

For a Spanish-language version, see Form 14039-B (SP) PDF.

Do I Need to Use Form 14039-B?

Send us Form 14039-B if you get a:

  • Rejection notice for an electronically filed return because we already have a return on file for that same period
  • Notice about a tax return that you didn't file
  • Notice about Forms W-2 filed with the Social Security Administration that you didn't file
  • Notice of a balance due that you do not owe
  • You get a notice for a business, but you never applied for an EIN

Do not send us Form 14039-B if:

  • Your business, estate, trust or exempt organization had a data breach with no tax-related impact to your business.
    • For example, a business has a breach of their computer system, but they find no evidence that fraudulent tax returns or Forms W-2 are being filed
