The Office of the International Tax Counsel (ITC) develops and reviews policy, legislation, regulations, revenue rulings, revenue procedures, and other published guidance dealing with all aspects of international income tax law. ITC is responsible for advising the Assistant Secretary (Tax Policy) and other Treasury officials in connection with the formulation of the Administration's international taxation policy; for formulating, analyzing, and reviewing international taxation legislation; and for preparing the Administration’s testimony on such legislation. ITC advise congressional staff in drafting legislation and in documenting the legislative history of international tax legislation.
In addition, the office is responsible for negotiating and reviewing income tax and estate and gift tax treaties with foreign countries and coordinating tax treaty matters with the State Department and the Congress. Two important purposes of these treaties are to help reduce international double taxation and thereby facilitate a freer movement of trade and capital flows, and to improve taxpayer compliance. In consultation with IRS, ITC is responsible for review of all Treasury regulations and IRS revenue rulings, revenue procedures, and other published guidance relating to international tax issues.
ITC attorneys serve as the official representatives of the United States in various international organizations including the Organisation for Economic Cooperation and Development.
