The current tax treaty network was developed in the 1920s and 1930s in order to prevent double residence/source taxation. This kind of double taxation rarely exists any more because most countries have adopted either an exemption system or a foreign tax credit regime in their domestic...

A central premise of tax scholarship of the last thirty years has been the greater mobility of capital than labor. Recently, scholars such as Edward Kleinbard have recommended that the US adopt a variant of the 'dual income tax' model used by the Scandinavian countries, under which income from...

On April 26, 2017, President Trump issued a one-page tax reform outline that included “territoriality,” i.e., exempting from tax dividends from the non-Subpart F income of controlled foreign corporations. Territoriality is also included in the House GOP “Better Way” Blueprint and was...

The “Unified Framework for Fixing Our Broken Tax Code” (the “Framework”) released by the “Big Six” group of Treasury, White House and Congressional leaders on September 27 has been the focus of a lot of commentary. Most of the comments have focused on the distributive aspects of the...

Customary international law is law that “results from a general and consistent practice of states followed by them from a sense of legal obligation.” “International agreements create law for states parties thereto and may lead to the creation of customary international law when such...

Since the 1990s, the US tax treaty network has expanded to include most large developing countries. However, there remains a glaring exception: The US only has two tax treaties in Latin America (Mexico and Venezuela), and one pending tax treaty (Chile).
