Summary

The IRS Whistleblower Program Improvement Act changes how award decisions are reviewed, guarantees anonymity in court, adds interest to delayed payments, and shields awards from sequestration. It also requires the IRS to publish a short list of the most common tax‑avoidance schemes reported by whistleblowers. The changes aim to encourage more people to report tax fraud and to ensure they are fairly compensated.
