The growing internationalization of both economic agents and operations creates additional challenges for the application of national tax systems, which generally lack appropriate legal instruments to solve the emerging issues.

Under those circumstances, the Iberoamerican Observatory of International Taxation (OITI) was created in 2010 as a common space for academics, practicing professionals, tax administrations and judges to study, exchange information and debate on fiscal law matters. In addition, the OITI encourages research and development of specialized knowledge regarding international taxation among new generations of tax attorneys.
