The Internal Revenue Service (IRS) offers substantial rewards for information on people and businesses that don’t pay the taxes they owe the United States government. The IRS Whistleblower Office can award whistleblowers up to 30 percent of additional taxes, penalties and other amounts it collects following a tip.
If you suspect an individual or business is not complying with United States’ tax laws, mail a completed Form 211, Application for Award for Original Information, with an original signature to the Whistleblower Office using the address on the form. Include copies of all relevant supporting documentation in your possession.
See Whistleblower-Informant-Award, How to File a Whistleblower Award Claim and The Whistleblower Law on IRS.gov for more information. If you have any additional questions, you may call the Whistleblower office in the United States at 801-620-2169.
If you would like to report tax noncompliance and are not interested in an award, or you have other information you believe may be of interest to the IRS, visit Report Suspected Tax Fraud Activity on IRS.gov for information on how to submit a report.
