Since its establishment in 2007, the IRS’ Whistleblower Office has awarded more than $1.3 billion to whistleblowers who have helped the agency recover more than $7 billion in delinquent taxes, interest and penalties. Now, the Whistleblower Office is revamping its operations to encourage even more whistleblowers to come forward. For corporate taxpayers, whistleblower complaints can create substantial liability exposure, and even when a whistleblower’s allegations are unfounded, avoiding unnecessary liability requires the representation of an experienced Washington D.C. tax lawyer.
