Tax Whistle Blower Claim

Form 211

To make a claim, an informant must file a Form 211 (Rev. December, 2007), Application for Award for Original Information.  The informant is required to provide his or her name, address, phone number, social security number, and date of birth on the form, in order to ensure that the IRS will be able to contact the whistleblower with any questions and in order to ensure that the IRS can send the whistleblower an award check.  The second page of the form describes in detail the information that the informant should provide to the IRS. The reason they ask for this information is simple: they need to know who to pay the award to.

Form 211 also asks informants to provide an estimate of the tax owed, the pertinent facts in the case and an explanation of how the informant obtained the information.  In signing the form, the informant makes a declaration under penalty of perjury that the information provided on the form is truthful. 

Form 211 should be sent, along with any additional documentation, to:
