IRS Whistleblower Program

The IRS Whistleblower Program offers monetary awards and anti-retaliation protections to individuals disclosing tax evasion and fraud. Since 2007, the program has awarded whistleblowers over $1 billion based on the collection of over $6 billion in back taxes, interest, penalties, and criminal fines and sanctions. Types of Fraud Covered by the IRS Whistleblower Program:

  • Offshore Tax Havens — when a company knowingly moves money to a bank in another country to avoid reporting taxable income in the U.S.;
  • Shell Accounts — setting up multiple bank accounts and circulating money across these accounts to evade or avoid taxes;
  • False Reporting — reporting false information on tax returns, such as underreporting revenues or taxable income;
  • Pyramiding — withholding employee taxes and intentionally not remitting taxes to the IRS, then filing bankruptcy and starting another company;
  • Failure to Pay or Report Payroll Taxes — failing to file employment tax returns or pay employment taxes on wages.

How to Report Someone to the IRS

Any individual with original information about tax fraud or large-scale tax evasion may blow the whistle to the IRS. Individuals do not need to be U.S. citizens or to be located in the U.S. to qualify.

The first step in blowing the whistle to the IRS is to hire an experienced tax whistleblower attorney. With the assistance of an attorney, a whistleblower may then file an IRS Form 211, an Application for Award for Original Information, with specific and credible information on tax fraud.
