The United States Department of Justice Tax Division is responsible for the prosecution of both civil and criminal cases arising under the Internal Revenue Code and other tax laws of the United States. The Division began operation in 1934, under United States attorney general Homer Stille Cummings, who charged it with primary responsibility for supervising all federal litigation involving internal revenue (following an executive order from President Franklin Delano Roosevelt).
The United States Department of Justice (DOJ) is an executive department of the United States federal government that oversees the domestic enforcement of federal laws and the administration of justice. It is equivalent to the justice or interior ministries of other countries. The department is headed by the U.S. attorney general, who reports directly to the president of the United States and is a member of the president's Cabinet. Pam Bondi has served as U.S. attorney general since February 4, 2025.
The Justice Department contains most of the United States' federal law enforcement agencies, including the Federal Bureau of Investigation, the U.S. Marshals Service, the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Drug Enforcement Administration, and the Federal Bureau of Prisons. The department also has eight divisions of lawyers who represent the federal government in litigation: the Criminal, Civil, Antitrust, Tax, Civil Rights, Environment and Natural Resources, National Security, and Justice Management Divisions. The DOJ includes the U.S. Attorneys' offices for each of the 94 U.S. federal judicial districts.
