The Internal Revenue Service (IRS) Whistleblower Office (WO) is responsible for processing thousands of tax whistleblower claims annually for two related whistleblower programs: for claims of $2 million or less, the 7623(a) program, and for claims over $2 million, the 7623(b) program. The whistleblower claim review process takes several years to complete, and GAO found that the WO is not using available capabilities to track and monitor key dates in its claim management system. Without available information on key dates related to award review and payments, the WO is unable to assess its performance against timeliness targets and risks unnecessarily delaying award payments.
Tax whistleblowers who report on the underpayment of taxes by others have helped IRS collect almost $2 billion in additional revenue since 2011, when the first high-dollar claim was paid under the expanded program that pays qualifying whistleblowers a minimum of 15 percent of the collected proceeds. These revenues help reduce the estimated $450 billion tax gap—the difference between taxes owed and those paid on time.Read the full report
