Title 5 › PART I — THE AGENCIES GENERALLY › CHAPTER 4 — INSPECTORS GENERAL › § 412
Gives the Secretary of the Treasury the power to control the Treasury Inspector General when an audit or investigation would need very sensitive information. That includes ongoing criminal probes, undercover work, identities of secret or protected witnesses, intelligence or counterintelligence, policy debates or data that could strongly affect markets, or anything that would seriously threaten national security or protected people. The Secretary can stop or limit an audit, block access to that information, or forbid subpoenas if needed to prevent disclosure or to protect national interests. If the Secretary acts, they must give the Inspector General a written explanation. The Inspector General must send that notice within 30 days to specific Senate and House committees. The Secretary cannot use these powers over the Treasury Inspector General for Tax Administration (TIGTA). Makes the Treasury Inspector General responsible for overseeing internal investigations at the Tax and Trade Bureau, and allows that Inspector General to start audits or investigations across the Department of the Treasury. If the Inspector General tells the head of the bureau in writing that they are investigating a matter, no other Treasury Inspector General investigation of that same matter may be started or continue. TIGTA may access tax returns only under Internal Revenue Code section 6103 and must follow the record-keeping and safeguards required by that code. Audits or investigations do not change final decisions under Internal Revenue Code section 6406. Reports required to Congress must go to certain committees within the same 7-day period. TIGTA handles all Inspector General duties related to the IRS, may enforce specified criminal tax laws (including carrying firearms), protect IRS employees from external threats, report suspected federal crimes to the Attorney General, and must follow rules barring recent IRS employees from certain TIGTA leadership roles (no IRS employment in the 2 years before appointment and no IRS employment for 5 years after leaving; includes certain assistant and deputy IG positions, effective November 27, 2017). The Commissioner of Internal Revenue or the IRS Oversight Board can request TIGTA audits; if TIGTA declines it must explain in writing, and final audit reports and lists of completed investigations must be provided to them.
