Can you fax Form 211 to the IRS? No.
No. The IRS does not accept Form 211 by fax — it requires an original signature under penalty of perjury.
Because a whistleblower award application must be signed under penalty of perjury, the IRS does not provide a fax number for Form 211. You can submit it electronically through the IRS whistleblower portal, or mail the signed form to the IRS Whistleblower Office in Ogden, Utah.
What Is Form 211?
Form 211, Application for Award for Original Information, is filed by a whistleblower who provides the IRS with specific and credible information about a person or business that has underpaid taxes or violated the tax laws. If the information leads to the collection of taxes, penalties, and interest, the whistleblower may be eligible for a monetary award from the IRS Whistleblower Office.
How to File Form 211 the Correct Way
The IRS gives whistleblowers two official ways to submit Form 211. Either way, the application must be signed under penalty of perjury.
Submit online through the IRS Form 211 portal

- •Confusing Form 211 (whistleblower award) with Form 3949-A (reporting fraud with no award)
- •Trying to fax it — the IRS does not offer a fax number for Form 211
