SUBJECT: Responsibilities of and to the Inspector General

  1. PURPOSE.  This Directive summarizes the authority of the Treasury Inspector General (IG), the scope of the IG’s audit, investigative, and oversight jurisdiction, and the reporting and other responsibilities of Department of the Treasury officials and employees to the Office of Inspector General (OIG). It identifies those Treasury bureaus, offices, and programs that are subject to the authority of the Department’s other inspectors general, the Treasury Inspector General for Tax Administration (TIGTA), the Special Inspector General for the Troubled Assets Relief Program (SIGTARP), and the Special Inspector General for Pandemic Recovery (SIGPR).
  2. SCOPE.  This Directive applies to all bureaus, offices, organizations, and programs in the Department of the Treasury, with certain exceptions. Programs, operations, events, and matters arising in or concerning the Internal Revenue Service (IRS), the IRS Office of Chief Counsel, or the IRS Oversight Board, are within the sole audit, investigative, and other oversight jurisdiction of the TIGTA. Similarly, events and matters relating to the Troubled Assets Relief Program (TARP) are within the sole audit, investigative, and other oversight jurisdiction of the SIGTARP; and programs, operations, events and matters concerning the Coronavirus Economic Stabilization Act (Pub. L. 116-136, Title IV, Subtitle A), fall under the jurisdiction of the SIGPR.
  3. POLICY.  It is the policy of the Department of the Treasury to fully support the OIG in its oversight work, to fully assist and cooperate with its inquiries, and to require its officers, employees, contractors, grantees, and all other responsible persons to fully assist and cooperate with its inquiries. This policy is enforced by Treasury Employee Rule of Conduct 31 Code of Federal Regulations (CFR) 0.210, Cooperation with official inquiries, which requires that “Employees directed by competent Department or other federal authority to provide oral or written responses to questions, or to provide documents and other materials concerning matters of official interest, shall timely respond fully, truthfully, and, when required, under oath.”
  4. RESPONSIBILITIES. This section sets out the authorities and responsibilities of the OIG and the responsibilities of Treasury employees, contractors, grantees, and other affected persons and entities to provide information and assistance to the OIG.
    The Inspector General is the head of the OIG, a statutorily established office of the Department of the Treasury (hereafter Treasury). The OIG was established by the Inspector General Act Amendments of 1988 (Pub. L. 100-504). Treasury Order (TO) 114-01 recognizes that establishment and contains Secretarial delegations of authority to the IG. The IG's duties pursuant to the Program Fraud Civil Remedies Act are found in 31 CFR Part 16. The OIG is independent of the Department and all other offices within Treasury. The IG reports to the Secretary through the Deputy Secretary. The organization and functions of the OIG are set forth in Treasury Directive (TD) 27-12.

      3. 3) All Treasury employees must provide to the IG and to that official's duly authorized representatives full, free, and unrestricted access to Treasury activities, property, data, correspondence, records, information technology systems, and any other information that the IG determines is necessary to an audit, investigation, or other official inquiry. In the case of classified documents, OIG employees accessing information shall comply with applicable security rules and regulations. If such records, etc., include material protected by 26 USC 6103, the OIG shall comply with the requirements and restrictions of such section regarding access to such information, and its proper use, dissemination, storage, and safeguarding.
      4. 4) All Treasury employees shall cooperate fully with duly authorized representatives of the OIG by disclosing complete and accurate information pertaining to matters being investigated, audited, or reviewed by the OIG. If the employee is the subject of an investigation, the employee will be afforded all required rights.

        3. c) Upon completion of an OIG investigation, the IG or the AIGI shall refer any finding of a criminal violation directly to the Attorney General or the appropriate U.S. Attorney.

        8. h) If the IG determines that an investigation is appropriate for referral to the General Counsel or designee, pursuant to the Program Fraud Civil Remedies Act, the IG may submit the Report of Investigation to the General Counsel or designee pursuant to 31 CFR Part 16.4.
        9. i) This paragraph will not apply to whistleblower complaints concerning programs, operations, events and matters within the jurisdiction of another Treasury Inspector General, in which case the Secretary may refer the OSC request to that office for the investigation pursuant to 5 USC 1213.
      16. 16) The OIG provides or supervises all audit services to the programs and operations of the Treasury within its jurisdiction.
        1. a) The OIG formulates Department-wide audit policies and priorities and ensures that all audits performed within the Department, whether performed by Treasury or outside auditors, are in accordance with standards established by the Comptroller General of the United States for audits of Federal entities.

        4. d) The action official will reply to the IG in writing within 30 calendar days of the date of the draft report, unless otherwise provided in the report transmittal. The reply will describe actions taken and planned, target dates for any incomplete corrective action, and reasons for any disagreement with the draft report.
        5. e) The reply will be incorporated as appropriate into the final audit report, which will then be distributed to the action official and others who may have an official interest in the subject of the report. If the reply is not received within 30 calendar days and an extension has not been granted, the report may be issued without the reply. Extensions should be requested in writing and should be from the action official to the OIG official who signed the report.
        6. f) Reports on pre-award audits of contract proposals will be issued in final without written responses.
