Under Internal Revenue Code Section 7623(a), the IRS shall pay awards to people who provide “specific and credible information” to the IRS if the information results in the collection of taxes, penalties, interest, or other amounts from a noncompliant taxpayer. Guaranteed awards, however, are limited to individuals who provide information about significant tax issues. “Significant” is defined by the IRS as taxes, penalties, and interest owed in excess of $2 million. Thus, to meet the $2 million threshold—including back taxes, interest and penalties—the noncompliant taxpayer should have an annual gross income of more than $200,000. If the IRS successfully obtains a recovery from such a taxpayer, the IRS is required to pay the whistleblower between 15 and 30 percent of the recovery. If the whistleblower is not satisfied with the reward, he or she may appeal to the U.S. Tax Court. In cases involving less than $2 million, payment of an award to the whistleblower is discretionary, with a maximum of 15 percent of the recovery and no right of appeal.
