In the United States, Office of Inspector General (OIG) is a generic term for the oversight division of a federal or state agency aimed at preventing inefficient or unlawful operations within their parent agency. Such offices are attached to many federal executive departments, independent federal agencies, as well as state and local governments. Each office includes an inspector general and employees charged with identifying, auditing, and investigating fraud, waste, abuse, embezzlement and mismanagement of any kind within the executive department.
The United States Office of Special Counsel (OSC) is a permanent independent federal investigative and prosecutorial agency whose basic legislative authority comes from four federal statutes: the Civil Service Reform Act, the Whistleblower Protection Act, the Hatch Act, and the Uniformed Services Employment and Reemployment Rights Act (USERRA). OSC's primary mission is the safeguarding of the merit system in federal employment by protecting employees and applicants from prohibited personnel practices (PPPs), especially reprisal for "whistleblowing." The agency also operates a secure channel for federal whistleblower disclosures of violations of law, rule, or regulation; gross mismanagement; gross waste of funds; abuse of authority; and substantial and specific danger to public health and safety. In addition, OSC issues advice on the Hatch Act and enforces its restrictions on partisan political activity by government employees. Finally, OSC protects the civilian employment and reemployment rights of military service members under USERRA. OSC has around 140 staff, and the Special Counsel is an ex officio member of Council of Inspectors General on Integrity and Efficiency (CIGIE), an association of inspectors general charged with the regulation of good governance within the federal government.

Internal Revenue Service, Criminal Investigation (IRS-CI) is the United States federal law enforcement agency responsible for investigating potential criminal violations of the U.S. Internal Revenue Code and related financial crimes, such as money laundering, currency transaction violations, tax-related identity theft fraud and terrorist financing that adversely affect tax administration. While other federal agencies also have investigative jurisdiction for money laundering and some Bank Secrecy Act violations, IRS-CI is the only federal agency that can investigate potential criminal violations of the Internal Revenue Code, in a manner intended to foster confidence in the tax system and deter violations of tax law. Criminal Investigation is a division of the Internal Revenue Service, which in turn is a bureau within the United States Department of the Treasury.
The Office of the Inspector General (OIG) for the Department of Justice (DOJ) is responsible for conducting nearly all of the investigations of DOJ employees and programs. The office has several hundred employees, reporting to the Inspector General. Michael E. Horowitz has held the post since 2012.
The Department of Homeland Security Office of Inspector General was established along with the Department of Homeland Security itself in 2002 by the Homeland Security Act.

A tax protester is someone who refuses to pay a tax claiming that the tax laws are unconstitutional or otherwise invalid. Tax protesters are different from tax resisters, who refuse to pay taxes as a protest against a government or its policies, or a moral opposition to taxation in general, not out of a belief that the tax law itself is invalid. The United States has a large and organized culture of people who espouse such theories. Tax protesters also exist in other countries.
The Internal Revenue Service (IRS) is the revenue service for the United States federal government, which is responsible for collecting U.S. federal taxes and administering the Internal Revenue Code, the main body of the federal statutory tax law. It is an agency of the Department of the Treasury and led by the Commissioner of Internal Revenue, who is appointed to a five-year term by the President of the United States. The duties of the IRS include providing tax assistance to taxpayers; pursuing and resolving instances of erroneous or fraudulent tax filings; and overseeing various benefits programs, including the Affordable Care Act.
The Department of Defense Office of Inspector General is an independent, objective agency that provides oversight related to the programs and operations of the United States Department of Defense (DoD). DoD IG was created in 1982 as an amendment to the Inspector General Act of 1978.
The Department of Defense Whistleblower Program in the United States is a whistleblower protection program within the U.S. Department of Defense (DoD) whereby DoD personnel are trained on whistleblower rights. The Inspector General's commitment fulfills, in part, the federal mandate to protect whistleblowers. It also administers the Defense Intelligence Community Whistleblower Protection Program (DICWP), as a sub-mission for the intelligence community. The Inspector General's Defense Criminal Investigative Service also conducts criminal investigations which rely, in part, on Qui Tam relators.
The Special Inspector General for Afghanistan Reconstruction (SIGAR) is the U.S. government's leading oversight authority on Afghanistan reconstruction. Congress created the Office of the Special Inspector General for Afghanistan Reconstruction to provide independent and objective oversight of the Afghanistan Reconstruction funds. Under the authority of Section 1229 of the National Defense Authorization Act for Fiscal Year 2008, SIGAR conducts audit, inspections, and investigations to promote efficiency and effectiveness of reconstruction programs, and to detect and prevent waste, fraud, and abuse of taxpayer dollars. SIGAR also has a hotline that allows individuals to report suspected fraud.
The Defense Intelligence Community Whistleblower Program (DICWP) is a sub-mission of the Department of Defense Whistleblower Program. In administering the DICWP, the Office of the Inspector General, U.S. Department of Defense (DoDIG) balances the competing national security and separation of powers interests raised by whistleblowing within the Defense Intelligence Community.The DoDIG provides a safe, authorized conduit for Defense Department whistleblowers to disclose classified information. The Inspector General also has authority to investigate whistleblowing reprisal allegations filed by civilian and military members of the Defense Intelligence Community. It therefore accepts the disclosures and provides source protection for those providing the information. The Department of Defense funds and supervises much of the Republic's intelligence gathering. DoD IG accordingly provides protection to a large number of civilian and military intelligence personnel.
In 2013, the United States Internal Revenue Service (IRS), under the Obama administration, revealed that it had selected political groups applying for tax-exempt status for intensive scrutiny based on their names or political themes. This led to wide condemnation of the agency and triggered several investigations, including a Federal Bureau of Investigation (FBI) criminal probe ordered by United States Attorney General Eric Holder. Conservatives claimed that they were specifically targeted by the IRS, but an exhaustive report released by the Treasury Department's Inspector General in 2017 found that from 2004 to 2013, the IRS used both conservative and liberal keywords to choose targets for further scrutiny.
Lois Gail Lerner is an American attorney and former United States federal civil service employee. Lerner became director of the Exempt Organizations Unit of the Internal Revenue Service (IRS) in 2005, and subsequently became the central figure in the 2013 IRS targeting controversy in the targeting of politically aligned groups, either denying them tax-exempt status outright or delaying that status until they could no longer take effective part in the 2012 election. On May 10, 2013, in a conference call with reporters, Lerner apologized that Tea Party groups and other groups had been targeted for audits of their applications for tax-exemption. Both conservative and liberal groups were scrutinized. Only three groups—all branches of the Democratic group Emerge America—had tax exemptions revoked. Lerner resigned over the controversy. An investigation by the U.S. Department of Justice and Federal Bureau of Investigation, completed in 2015, found "substantial evidence of mismanagement, poor judgment and institutional inertia" but "found no evidence that any IRS official acted based on political, discriminatory, corrupt, or other inappropriate motives that would support a criminal prosecution".
An IRS impersonation scam is a class of telecommunications fraud and scam which targets American taxpayers by masquerading as Internal Revenue Service (IRS) collection officers. The scammers operate by placing disturbing official-sounding calls to unsuspecting citizens, threatening them with arrest and frozen assets if thousands of dollars are not paid immediately, usually via gift cards or money orders. According to the IRS, over 1,029,601 Americans have received threatening calls, and $29,100,604 has been reported lost to these call scams as of March 2016. The problem has been assigned to the Treasury Inspector General for Tax Administration.
