Origin and History

In 1965, tax administration authorities from the countries of the Americas were invited to learn about and discuss in the United States of America the fundamental tax administration problems. On that occasion, Messrs. Sheldon Cohen and Harold Moss, Commissioner and Director of the International Assistance Service of the U.S. Internal Revenue Service, respectively, had the vision of creating an organization that could serve as permanent forum for considering the tax administration problems.
