In two recent cases, the United States Tax Court (Tax Court) has explored the bounds of the anonymity protection afforded to potential whistleblowers under the court’s rules and other authorities. Tax Court Rule 345 relates to privacy protections for filings in whistleblower actions.  Under paragraph (a), a whistleblower may move the court for permission to proceed anonymously.  In order to proceed anonymously, the whistleblower must provide a sufficient, fact-specific basis for anonymity.  Specifically, the Tax Court has held that “[a] whistleblower is permitted to proceed anonymously if the whistleblower presents a sufficient showing of harm that outweighs counterbalancing societal interest in knowing the whistleblower’s identity.”  (Whistleblower 10949-13W v. Commissioner, T.C. Memo 2014-94, at 5).  However, the balance of harm to societal interest may shift as the case progresses, thereby justifying disclosure after anonymity has been granted.  See Tax Court Rule 345(b).
