Tax Treaties, The Constitution, And The Noncompulsory Payment Rule, Reuven S. Avi-Yonah
Tax Treaties, The Constitution, And The Noncompulsory Payment Rule, Reuven S. Avi-Yonah
Articles
US Tax treaties have been regarded as self-executing since the first treaty (with France) was ratified in 1932. Rebecca Kysar has argued this raises a doubt on whether the treaties are constitutional, because tax treaties (like other treaties) are negotiated by the executive branch and ratified by the Senate with no involvement by the House, and all tax-raising measures must originate in the House under the Origination Clause (U.S. Const. Art I, section 7, clause 7). Her preferred solution is to make tax treaties non-self executing, but that would reverse the universal practice since 1932, and is therefore unlikely. Moreover, …
If Not Now, When? Us Tax Treaties With Latin America After Tcja, Reuven S. Avi-Yonah
If Not Now, When? Us Tax Treaties With Latin America After Tcja, Reuven S. Avi-Yonah
Law & Economics Working Papers
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). The traditional explanation for why the US has no treaty with, for example, Argentina or Brazil is the US refusal since 1957 to grant tax sparing credits to developing countries. Before the Tax Cuts and Jobs Act of 2017 (TCJA), this explanation was wrong, because the combination of deferral and cross-crediting meant that tax holidays in a source country …
Does Customary International Tax Law Exist?, Reuven S. Avi-Yonah
Does Customary International Tax Law Exist?, Reuven S. Avi-Yonah
Law & Economics Working Papers
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 agreements are intended for adherence by states generally and are in fact widely accepted.” Does customary international law (CIL) exist in tax? There are over 3,000 bilateral tax treaties, and they are about 80% identical to each other, but do they create CIL that binds in the absence of a binding treaty, like for example the …
Formulary Apportionment And International Tax Rules, Reuven S. Avi-Yonah, Zachee Pouga Tinhaga
Formulary Apportionment And International Tax Rules, Reuven S. Avi-Yonah, Zachee Pouga Tinhaga
Book Chapters
Any proposal to adopt unitary taxation (UT) of multinationals has to contend with whether such taxation is compatible with existing international tax rules, and, in particular, with the bilateral tax treaty network. Indeed, some researchers have argued that the separate accounting (SA) method and the arm’s length standard (ALS), introduced in the early twentieth century, are so embodied in the treaties that they form part of customary international law, and are binding even in the absence of a treaty. We disagree, because the unitary approach is just as widely embodied in most of the current international tax treaties, and, where …
Tax Competition, Tax Arbitrage And The International Tax Regime, Reuven S. Avi-Yonah
Tax Competition, Tax Arbitrage And The International Tax Regime, Reuven S. Avi-Yonah
Articles
In the past ten years, I have argued repeatedly that a coherent international tax regime exists, embodied both in the tax treaty network and in domestic laws, and that it forms a significant part of international law (both treaty-based and customary). The practical implication is that countries are not free to adopt any international tax rules they please, but rather operate in the context of the regime, which changes in the same ways international law changes over time. Thus, unilateral action is possible, but is also restricted, and countries are generally reluctant to take unilateral actions that violate the basic …
The New United States Model Income Tax Convention, Reuven S. Avi-Yonah, Martin B. Tittle
The New United States Model Income Tax Convention, Reuven S. Avi-Yonah, Martin B. Tittle
Articles
On 15 November 2006, the United States Treasury released its long-awaited new Model Income Tax Convention (“New Model”), which replaced the 1996 US Model (“Old Model”). This article reviews some of the major differences between the New and Old Models, as well as some of the major differences between the New Model and the current (2005) OECD Model Tax Convention. The article also discusses some new trends in US treaty policy which are not reflected in the New Model. The article concludes by evaluating the New Model in light of the emerging trend to use tax treaties not just to …
International Tax Law As International Law, Reuven S. Avi-Yonah
International Tax Law As International Law, Reuven S. Avi-Yonah
Articles
Is international tax law part of international law? To an international lawyer, the question posed probably seems ridiculous. Of course international tax law is part of international law, just like tax treaties are treaties. But to an international tax lawyer, the question probably seems less obvious, because most international tax lawyers do not think of themselves primarily as international lawyers (public or private), but rather as tax lawyers who happen to deal with crossborder transactions. And indeed, once one delves into the details, it becomes clear that in some ways international tax law is different from "regular" international law. For …
U.S. International Treatment Of Financial Derivatives, Reuven Avi-Yonah, Linda Swartz
U.S. International Treatment Of Financial Derivatives, Reuven Avi-Yonah, Linda Swartz
Articles
The current proposals to substitute consumption for income as the principal U.S. tax base have already been the topic of considerable commentary in these pages. However, one issue has received relatively little attention in the discussion of the various reform proposals: What potential complications are likely to arise if a single major player in the world's economy unilaterally adopts radical tax reform? The global economy is becoming more and more unified, with multinational corporations dominating world trade and trillions of dollars in portfolio investment flowing across national boundaries. In this economy, what would be the consequences if a single country, …
