A Gdpr-Compliant Fatca Structure?, Michael Hatfield

Articles

A 2025 Belgian Data Protection Authority (DPA) decision and ensuing preliminary questions referred by the Belgian Market Court to the Court of Justice of the European Union (CJEU) highlights the tension between the General Data Protection Regulation (GDPR) and the US Foreign Account Tax Compliance Act (FATCA) structure in Europe. The FATCA structure relies on intergovernmental agreements (FATCA IGAs) between the US and EU Member States. Under these agreements, Member State tax authorities transfer personal data of their citizens and residents to the US Internal Revenue Service (IRS). It may be determined that these transfers violate some or all of …

False Idols In The Early History Of International Taxation, Wei Cui

All Faculty Publications

A careful reading of recent scholarship on the early history of international taxation, especially on the League of Nations ’ work on ‘ double taxation ’ , ought to have dislodged many myths about this history. But more often than not, such scholarship is taken to offer mere details without altering our fundamental understanding. This chapter suggests that this reception refl ects a longstanding pattern in discourses about international taxation: participants perpetuate or cling onto narratives that are easily seen to be false. The chapter exposes this pattern by summarising evidence for four rarely-acknowledged conclusions about the League ’ s …

Taxing Ai, Assaf Harpaz

Scholarly Works

Artificial intelligence (AI) is poised to transform the distribution and sources of income, with some experts predicting widespread job displacement. Even under optimistic projections, AI is expected to exacerbate wealth inequality, given that the technology’s ownership and immense value are concentrated within a subset of Big Tech companies and AI startups. These outcomes will have far-reaching impacts on the federal tax system, which heavily relies on taxing individual labor income and payroll, rather than capital or consumption.

This Article argues that AI threatens to disrupt the tax system’s ability to fulfill its fundamental goals of raising revenue, redistributing income, and …

Was The Early U.S. Tax Treaty Program A One-Man Show?, Wei Cui

All Faculty Publications

This article examines the origins of the U.S. tax treaty program from the mid-1930s to the early 1950s. Drawing on congressional records and previously unexamined Treasury and State Department archives, it argues that the program was shaped to an extraordinary degree by a single Bureau of Internal Revenue official, Eldon P. King. Far from merely administering treaty policy, King effectively created and directed it: he developed legal justifications for treaty negotiations, selected negotiating partners, led negotiations, managed relations with the State Department, and helped secure Senate acceptance of the resulting agreements. The article shows how King transformed the limited treaty-related …

How The U.S. Constitution Shapes International Tax Law: Instrument Choice In Tax Agreements, Noam Noked, Young Ran (Christine) Kim, Reuven Avi-Yonah

Articles

The U.S. Constitution’s Treaty Clause, which requires Senate approval by a two-thirds vote for treaties, has significantly influenced the development of international tax law. This Article examines the implications of Senate supermajority requirements on bilateral and multilateral tax treaties and agreements, alternative instruments, relevant international tax standards, and global tax governance.

Historically, tax treaties have been approved exclusively as Article II treaties requiring Senate approval. The difficulty of entering into treaties with the United States has influenced the instrument choice and design of U.S. and international tax standards. To address this challenge, several U.S. and international tax reforms have employed …

Dividend Distribution Tax: More Than Meets The Eye - A Critical Analysis Of Polycab India Ltd. V. Assistant Commissioner Of Income-Tax, Ashrita Prasad Kotha

Articles

The case emanates from the dividend distribution tax (DDT) paid by Polycab on shares held by International Finance Corporation (IFC), one of its shareholders. IFC was set up by an international agreement to support the private sector in developing countries and was granted tax immunity on its income and transactions under the founding multilateral treaty and supporting domestic law. Polycab sought refund of DDT owing to IFC's immunity. The Income Tax Appellate Tribunal (ITAT) ruled in favour of Polycab by considering dividend distribution within the immunity clause and reading in an exemption into the income tax legislation. Significantly, the DDT …

The Forgotten Weapon: Section 891 And The Origins Of U.S. Retaliatory Tax Policy, Reuven S. Avi-Yonah, Gianluca Mazzoni

Articles

The original version of the One Big Beautiful Bill Act (P.L. 119-21) included section 899, which would have imposed retaliatory taxes on individuals and corporations from countries that apply “discriminatory or extraterritorial” taxes to U.S. corporations, defined specifically to include digital services taxes and the undertaxed profits rule of pillar 2.

However, on June 26 Treasury Secretary Scott Bessent announced that a compromise was reached on the UTPR, and as a result, section 899 was removed from the OBBBA. Now that section 899 is gone, section 891 is the most important part of the United States’ legislative armory against “discriminatory …

From Relic To Relevance, The Resurgence Of Tariffs, Reuven S. Avi-Yonah, Doron Narotzki, Tamir Shanan

Law & Economics Working Papers

Modern legal scholarship has largely relegated tariffs to economic analysis, overlooking their legal and policy significance. This article challenges that view by examining tariffs as a potential pillar of fiscal policy, exploring their viability as a revenue source alongside or in place of traditional income and corporate taxation. While historically central to U.S. government funding, tariffs diminished in importance with the rise of income taxation and trade liberalization. However, their recent resurgence as a tool for trade protection raises broader questions about their role in national economic strategy. This article critically assesses the feasibility of a tariff-based tax system, drawing …

Should The Oecd Accept Gilti As A Valid Iir?, Reuven S. Avi-Yonah

Articles

On June 26 Treasury Secretary Scott Bessent announced a deal with the G7 to accept the global intangible low-taxed income tax as a valid income inclusion rule tax and not apply the undertaxed profits rule to U.S. multinational enterprises. Bessent said a “joint understanding” among the United States and other countries will be announced soon. “OECD pillar 2 taxes will not apply to U.S. companies, and we will work cooperatively to implement this agreement across the OECD-G20 inclusive framework in coming weeks and months,” Bessent wrote. Soon after, Senate Finance Committee Chair Mike Crapo, RIdaho, and House Ways and Means …

Proposed Cloud Services Sourcing Rule: The Right Direction, Reuven Avi-Yonah, Jeffery M. Kadet, Karen Sam

Articles

This past January, in conjunction with the issuance of a final regulation (T.D. 10022) that treats income from defined cloud transactions as income from services, Treasury and the IRS released a proposed regulation (REG-107420-24) on the sourcing of that income. In 2019 a Treasury official had asked the tax community for feedback on whether specific cloud transaction sourcing rules were needed, and the preamble to a 2019 proposed regulation asked for comments on “administrable rules for sourcing income from cloud transactions in a manner consistent with sections 861 through 865.” The feedback was “split almost evenly with regard to whether …

No Trade Wars Without Taxation -Who's To Blame, And What Comes Next?, Domenico Imparato, Reuven S. Avi-Yonah, Doron Narotzki

Law & Economics Working Papers

As tariff policy once again shapes U.S. trade strategy, this article makes a foundational claim: trade wars are, at their core, tax wars. Against the backdrop of escalating economic tensions with the United States’ trade partners, this article argues that tariffs cannot be understood apart from the fiscal architecture that sustains them. What appears to be protectionism often masks deeper structural asymmetries in the U.S. tax system.

The discussion proceeds through three interrelated dimensions: reshoring production, promoting fair trade, and raising revenue. In each, the interaction between tariffs and the tax system reveals deeper distortions. U.S. export mechanisms such as …

Where Intangibles Travel: Essays On The Tax-Motivated Geography Of Innovation And Capital, Xuerui Kou

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation explores how taxation and institutional environments shape the global strategies of United States multinational enterprises (MNEs), with a particular focus on intangible assets and the cross-border allocation of innovation. Positioned at the intersection of international trade, public economics, and innovation studies, the three chapters collectively examine firm responses to international tax incentives and regulatory asymmetries.

Chapter 1 introduces the motivation and theoretical foundations of the dissertation, reviews related literature, and outlines the core research questions and empirical strategies. It highlights the increasing policy and academic interest in the geographic mobility of intangible capital, particularly in the context of …

Fixing A 100-Year-Old Mistake, Michael J. Graetz

Faculty Scholarship

Posing the question of international tax cooperation versus competition reminds me of multiple-choice exams in which the right answer is “all of the above.” National interests determine which dominates at any given time. And in tax competition among nations, zero is not a lower bound.

In 1918, to encourage U.S. investments abroad, the United States enacted a credit for foreign taxes paid by U.S. companies and relinquished taxing rights to most foreign-source income. With the foreign tax credit, the United States assumed sole responsibility for reducing the double taxation of its residents and citizens. As the influential economist Edwin Seligman …

Canada's New Gaar Preamble: Pivoting Toward Fairness And Parliamentary Contemplation, Jinyan Li, Michael Conroy, Sebastien Tuli, Kitty Wang, Patrick White

Retaliatory Taxation, Reuven S. Avi-Yonah

Law & Economics Working Papers

This paper discusses the Trump administration's potential use of section 891 and pending legislation to apply retaliatory taxes to foreign countries that impose "discriminatory or extraterritorial" taxation on US multinationals.

Preface: The Field Of International Economic Law, Gregory Shaffer, Michael Waibel

Georgetown Law Faculty Publications and Other Works

This is the preface to our forthcoming book Advanced Introduction to International Economic Law for Edward Elgar Publishing. The book is unique in multiple ways. It is the first book that addresses the breadth of international economic law thematically, instead of serially by sub-field of law. We examine the history of key sub-fields, their contested functions, and the ways that they disparately address issues of liberalization and market access, discrimination, state regulatory policy space, fairness, governance and dispute resolution. Unlike law and economic accounts, we do not naturalize the “functions” of international economic law. Rather, we note how different actors …

Was The Niit A Treaty Override?, Reuven S. Avi-Yonah

Law & Economics Working Papers

Three court decisions have recently addressed the interaction of the Net Investment Income Tax (NIIT) and US tax treaties. The issue was whether the treaty provided an independent basis for crediting a foreign tax against the NIIT, because no such credit is available under the Code. First, in Toulouse, the Tax Court held that there was no treaty based credit. Second, in Christensen, the Court of Federal Claims held that a treaty-based credit was available, distinguishing Toulouse. Third, in Bruyea, the Court of Federal Claims issued a broader opinion that allowed the credit. Importantly, Bruyea addressed an issue that was …

Should The United States Abandon Citizenship-Based Taxation?, Reuven S. Avi-Yonah

Law & Economics Working Papers

President Trump proposed during the election campaign to end the "double taxation" of American citizens living overseas. To which the answer is, what double taxation? Americans living overseas already benefit from three significant provisions that in most cases prevent any double taxation, and because of these most of them do not have any U.S. tax liability. Those who do are typically wealthier, derive income from investments or from high wages, and are not subject to foreign tax because they live in tax havens or in countries that do not tax rich immigrants on foreign source income, and they do not …

Improper Use Of Tax Treaties And Source Taxation: Policy, Practice And Beyond, Eivind Furuseth, Jinyan Li

Conference Papers

The question of improper use of tax treaties (or treaty shopping) defies a simple or straightforward answer. The line between “proper use” and “improper use” a tax treaty depends on the determination of the intended use of a treaty provision by Contracting States (i.e. the common intention as well as the object and purpose of the treaty provision). As a treaty interpretation issue, that determination varies from country to country. Furthermore, the extent of taxpayers’ right to tax planning and expectation of tax certainty also varies across countries. Finally, the effect of domestic general-anti-avoidance rules (GAARs) and the new principal …

Weaponization Of Taxation: Sovereign Tax Immunity As A National Security Tool, Vinita R. Singh

Articles

Amidst calls to reconceptualize taxation as a national security tool, legislators are reexamining how the United States taxes foreign governments. Federal income taxation of foreign governments—what this Article terms “the law of immunity from taxation” or “sovereign tax immunity”—strongly influences whether and how foreign governments pursue investment in the United States. This impact on international business transactions indicates sovereign tax immunity has the potential to be a powerful national security tool. Yet, despite its import, the law of immunity from taxation has been underexplored and undertheorized. This Article steps into this gap in discourse by challenging the way recent legislative …

What Can One Learn From Chinese Tax Administration? A Precis Of The Administrative Foundations Of The Chinese Fiscal State (Cambridge University Press, 2022), Wei Cui

All Faculty Publications

The Administrative Foundations of the Chinese Fiscal State (Cambridge University Press 2022) explores how China developed a tax system to support its economic transformation. Among scholars who study taxation and economic growth, a familiar idea is that it is generally very difficult for poor countries to develop the state apparatus needed to raise revenue. The lack of revenue, in turn, prevents governments from providing critical public goods and services needed to spur economic growth. State capacity in taxation, therefore, is a major determinant of which countries become prosperous and which do not. An obvious question, then, is whether the evolution …

Un Tax Negotiations: North-South Tensions And The Challenge Of Institutional Legitimacy, Assaf Harpaz

Scholarly Works

The drafting process for a United Nations Framework Convention on International Tax Cooperation, along with two early protocols, is now underway. A UN framework convention represents a Global South effort to shift international tax policymaking from the OECD to the UN. For developing countries, the UN has long been viewed as a more inclusive space for tax policy negotiations, producing more favorable but historically less influential standards compared to the OECD.

Support for the UN framework convention, including its terms of reference, has been sharply divided across traditional Global North-South lines. The backlash following the OECD’s recent two-pillar reform triggered …

Global Tax Wars In The Digital Era, Assaf Harpaz

Scholarly Works

The digital economy fundamentally disrupts international tax principles that rely on physical presence. When a business earns income abroad, the country of residence (where the taxpayer resides) and the country of source (where income is generated) both have legitimate, competing claims to tax that income. The international tax system tends to favor residence-based taxation. The source country has the right to tax business profits only if the enterprise carries on a permanent establishment within its borders, which typically requires physical presence. The permanent establishment standard becomes flawed in a digital economy where profit shifting practices are abundant and businesses no …

Is The Obbba Compatible With Pillar 2?, Reuven S. Avi-Yonah

Articles

In this installment of Reflections With Reuven Avi-Yonah, Avi-Yonah compares House and Senate sections of the One Big Beautiful Bill Act and examines the potential effect on international tax relations. On May 22 the House of Representatives passed the One Big Beautiful Bill Act (OBBBA). The House version of the OBBBA extended the Tax Cuts and Jobs Act tax cuts but did not significantly change its international provisions. It did, however, contain proposed section 899, which would have imposed enhanced taxation on residents and corporations from countries that have “discriminatory or extraterritorial taxes,” defined to include primarily the undertaxed profits …

Eliminating Qbai - One Step Forward, Two Steps Back?, Reuven S. Avi-Yonah

Articles

In this installment of Reflections With Reuven Avi-Yonah, Avi-Yonah explains what makes an effective U.S. tax regime and uses those attributes to evaluate the One Big Beautiful Bill Act. There is plenty to criticize about the One Big Beautiful Bill Act (OBBBA, P.L. 119-21), signed into law by President Trump on July 4. It increases the deficit by about $4 trillion when the interest costs from the additional borrowing are included, and by about $5.5 trillion if its provisions are made permanent in 2029, like the Tax Cuts and Jobs Act provisions were in 2025. It is distributionally skewed to …

Us Policy And Pillar 2: The Evolution Of Us Tax Policy Toward Oecd Pillar 2 And Its Global Implications, Reuven S. Avi-Yonah

Articles

This paper analyzes the United States’ evolving position on OECD Pillar 2, focusing on the Trump administration’s initial rejection and subsequent negotiations to exempt US multinationals from the Undertaxed Profits Rule (UTPR). It examines the legislative and diplomatic strategies that led to international acceptance of GILTI as a valid IIR. The analysis concludes that the resulting compromise preserves US tax sovereignty while maintaining the global framework’s integrity.

Taxation’S Limits, Luís C. Calderón Gómez

Articles

Countless pages have been devoted to the question of why everyone should pay tax, yet its opposite has gone largely unnoticed: why should some people and organizations not pay tax? Our tax system exempts from ordinary income taxation a wide and diverse array of people and organizations engaged in significant economic activity—from parents providing childcare services for their family to consular activities and charities operating animal shelters—seemingly without a convincing explanation. Perhaps because of the dizzying diversity of tax-exempt activities, scholars and policymakers have avoided comprehensively or coherently justifying our exemption regimes.

This Article develops a novel normative theory that …

Challenging The Johnson Amendment: What Safe Space Gets Right - And Wrong, Benjamin Leff

Scholarly Articles in Law Reviews & Journals

There has long been a scholarly debate about the so-called Johnson Amendment, which is the statutory provision that prohibits charities from “intervening” in campaigns for public office. Some scholars argue that the Johnson Amendment, or at least the IRS’s interpretation of it, unconstitutionally prevents charities from exercising their fundamental rights to speech or religious liberty. Activists have tried to provoke IRS enforcement of the prohibition so they could argue their interpretation of the Constitution in court, but the IRS appeared to be avoiding litigation on the issue. On March 18, Students and Academics for Free Expression, Speech, and Political Action …
