Office of Chief Counsel (IRS) is the in-house legal office of the Internal Revenue Service that provides legal advice, representation, and regulatory drafting support concerning Internal Revenue Code, tax enforcement, and fiscal policy matters. Established in the early 20th century amid expanding federal tax administration, the office coordinates litigation in the United States Tax Court, United States District Courts, and federal appellate courts, while advising the Department of the Treasury and other executive branch entities. It serves as a key legal advisor to tax administrators, influencing regulatory rulemaking, guidance, and compliance strategies across federal agencies.

History

The office traces institutional roots to legal divisions created during the post‑World War I federal expansion and the 1913 ratification of the Sixteenth Amendment to the United States Constitution, with formalization accelerating during the 1920s under leaders tied to the Department of the Treasury and the evolving Internal Revenue Service. Throughout the New Deal era and the tax law reforms culminating in the Internal Revenue Code of 1954 and Internal Revenue Code of 1986, the office expanded its litigation and advisory roles, interacting with entities such as the United States Department of Justice, the United States Tax Court, and the Treasury Secretary's policy staff. In later decades, episodes involving the Tax Reform Act of 1986, the IRS Restructuring and Reform Act of 1998, and the post‑September 11 attacks fiscal shifts shaped its procedural and technological modernization.

Organization and Structure

The Office is headquartered in Washington, D.C. with regional and district counsel offices located in major centers including New York City, Los Angeles, Chicago, Houston, and San Francisco. It is led by the Chief Counsel who reports to the Commissioner of Internal Revenue and coordinates with the Treasury General Counsel. Subunits include divisions specializing in Corporate taxation (handled in coordination with representatives involved in cases before the United States Court of Appeals for the Federal Circuit), Individual taxation (frequently litigated in the United States Court of Appeals for the Second Circuit and United States Court of Appeals for the Ninth Circuit), International taxation (engaging with Organisation for Economic Co-operation and Development standards and bilateral tax treaties), Criminal Tax, Procedure and Administration, and Passthrough entities practice groups. The office employs attorneys who are members of bars across jurisdictions including the District of Columbia Bar, the New York State Bar Association, and the California Bar.

Functions and Responsibilities

Primary responsibilities include advising the Internal Revenue Service on interpretation of the Internal Revenue Code and associated Treasury regulations, representing the Service in litigation before the United States Tax Court, United States District Courts, and federal appellate courts including the United States Court of Appeals for the D.C. Circuit, and assisting in drafting regulatory guidance and notices such as Revenue Rulings and Revenue Procedures. The office provides counsel on enforcement techniques used by Criminal Investigation (IRS) agents, supports administrative appeals before the Office of Appeals (IRS), and reviews tax forms and publications tied to the Internal Revenue Manual. It also issues Chief Counsel Advice documents and participates in interagency coordination with bodies like the Financial Crimes Enforcement Network and the Office of Foreign Assets Control.

Notable Opinions and Litigation

The Office has authored influential litigation positions and opinions in landmark tax disputes involving cases adjudicated by the United States Supreme Court, the United States Court of Appeals for the Federal Circuit, and the United States Tax Court. Notable matters include positions in litigation surrounding corporate reorganizations adjudicated under precedent originating in the Supreme Court of the United States and disputes over transfer pricing that implicated international agreements such as bilateral tax treaties and OECD guidance. The office’s briefs and opinions have influenced outcomes in cases addressing the Economic Recovery Tax Act, the Tax Reform Act of 1986, and controversies over tax shelters litigated against firms and individuals appearing in federal dockets.

Relationship with IRS and Treasury

The Office maintains a dual role advising both the Internal Revenue Service operational leadership and coordinating with the Department of the Treasury on policy and regulatory development. It provides legal review of Treasury regulations proposed by the Office of Tax Policy (Treasury) and supports Treasury negotiations with foreign counterparts, including work tied to the Foreign Account Tax Compliance Act framework and tax treaty negotiations. In enforcement contexts, it interfaces with the Justice Department for civil and criminal referrals and assists the Commissioner of Internal Revenue in balancing enforcement priorities with taxpayer rights articulated under statutes such as the Taxpayer Bill of Rights.

Leadership and Chief Counsels

Chief Counsels have included senior attorneys with backgrounds in prominent law firms, federal practice, and academia who later engaged with institutions such as the American Bar Association, leading universities like Georgetown University Law Center, Harvard Law School, and appellate practice before the United States Court of Appeals for the Second Circuit. The Chief Counsel serves as principal legal advisor to the Commissioner of Internal Revenue and liaises with the Treasury Secretary and Solicitor General of the United States on matters escalated to the Supreme Court of the United States.

Criticism and Controversies

The Office has faced criticism and controversy in contexts ranging from alleged politicization during enforcement decisions, disputes over transparency in issuing Chief Counsel Advice and Internal Revenue Manual interpretations, to scrutiny in high‑profile audits and litigation involving prominent taxpayers and corporations often represented by firms such as Skadden, Arps, Slate, Meagher & Flom, Latham & Watkins, and Sullivan & Cromwell. Episodes tied to enforcement coordination with the Department of Justice and debated interpretations of the Internal Revenue Code have prompted congressional hearings in committees like the United States House Committee on Ways and Means and the United States Senate Committee on Finance.
