Can The Corporate Tax Be Delegated?, Reuven S. Avi-Yonah

Articles

In Learning Resources Inc., the Supreme Court held by a 6-3 majority that President Trump lacked the authority under the International Emergency Economic Powers Act (IEEPA) to impose tariffs. The main rationale was that tariffs are taxes and that IEEPA only authorized the president to “regulate” imports, not to tax them. In his majority opinion, Chief Justice John Roberts wrote: But the facial breadth of “regulate” places in stark relief what the term is not usually thought to include: taxation. The U.S.

Code is replete with statutes granting the Executive the authority to “regulate” someone or something. Yet the Government …

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 …

Tax Base Diversification As An Enforcement Tool, David Gamage, Brian Galle, Yulia Kuchumova

Faculty Publications

We examine when it is optimal to employ sales or VAT-type taxes as complements to a labor income tax. We find a Ramsey-type result in which each tax instrument should be imposed in inverse proportion to the combined elasticity of real and avoidance responses to the respective tax. Contrary to some prior results, we find that sales-type taxes are optimally non-zero across a variety of settings, and in particular when the (weighted) elasticity of taxable income with respect to the wage tax is greater than the cross-elasticity of taxable income with respect to the sales tax. We argue this parameter …

Are We Trapped By Realization?, Reuven S. Avi-Yonah

Articles

In this installment of Reflections With Reuven Avi-Yonah, Avi-Yonah examines the downsides of the realization requirement and potential solutions to them. In an excellent Tax Notes article, Steven Sheffrin recently mounted the most convincing defense of the realization requirement I have read. He explained that the case for taxing unrealized capital gains is based on the Haig- Simons definition of income. In this definition, income equals consumption plus savings when savings includes both realized and unrealized capital gains. If asset prices change because of changes in future cash flows, Haig-Simons income can provide an appropriate guide for designing tax policies.

Corporate Tax: Best Tool For Taxation's Regulation Goal, Reuven S. Avi-Yonah

Articles

In this installment of Reflections With Reuven Avi-Yonah, Avi-Yonah explains the three primary goals of taxation — revenue, redistribution, and regulation — and shows how VAT, the individual tax, and the corporate tax each uniquely match one of the goals. On January 20 President Trump signed two executive orders related to international taxation, marking a sharp policy shift from the prior administration. The first renounced any prior U.S. commitments to the OECD/inclusive framework global anti-base-erosion (GLOBE) project, stating that “the Global Tax Deal has no force or effect in the United States.” The order argued that the GLOBE project infringed …

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 …

Can The United States Curb Its Debt?, Reuven S. Avi-Yonah

Articles

After the upcoming presidential election, the United States is almost certainly going to have a president who is barred from running for reelection, regardless of the outcome in November. This situation has never happened before and it presents an important opportunity for fundamental tax reform.

Reimagining A U.S. Corporate Tax Increase As A Supplemental Subtraction Vat, Daniel S. Goldberg

Faculty Scholarship

The U.S. federal government raises tax revenue almost exclusively through income taxes, both corporate and individual, whereas its trading partners and competitors rely for their national revenue on both income taxes and “destination-based” value added taxes (VATs), which are not imposed on exports but are imposed on imports. As a result, U.S. corporations, which are subject to U.S. corporate income tax, may be at a serious trade disadvantage to competitor non-U.S. corporations with respect to both U.S. domestic sales and foreign sales, if the U.S. corporate income tax exceeds the foreign country’s income tax imposed on those competitors.

The Parallel March Of The Ginis: How Does Taxation Relate To Inequality, And What Can Be Done About It?, Reuven S. Avi-Yonah

Articles

The United States currently has one of the highest levels of inequality among industrialized economies. In addition, numerous scholars have shown that social mobility in the United States is significantly lower than it was in the period between 1945 and 1970, when inequality was declining. The combination of these trends is dangerous because it risks transforming the United States into a society where small elites capture most of the gains, a pattern in which growth cannot be sustained over time. The level of inequality in the United States after taxes and transfers are taken into account is much lower, but …

Stanley Surrey, The 1981 Us Model, And The Single Tax Principle, Reuven S. Avi-Yonah

Articles

2021 marks the fortieth anniversary of the 1981 US Model Tax Treaty as well as the fifth anniversary of the 2016 US Model Tax Treaty. The first author has repeatedly argued that the 1981 Model gave life to the single tax principle (‘STP’). The 2016 Model updates effectively implemented the principle that cross-border income should be taxed once – that is not more and but also not less than once. For example, the 2016 Model does not reduce withholding taxes on payments of highly mobile income that are made to related persons that enjoy low or no taxation with respect …

Afghanistan's New Vat, Part 1: Invoice Matching Or A Unitary Digital Invoice, Richard Thompson Ainsworth, Musaad Alwohaibi, Andrew Leahey, Yujin Li, Haseena Rahman

Faculty Scholarship

In the summer of 1990 two groundbreaking articles on business process re-engineering (BPR) were published, one by Thomas H. Davenport (a professor in information technology at Babson College) in the MIT Sloan Management Review, the other by Michael Hammer (a professor of computer science at MIT) in the Harvard Business Review. BPR is a management strategy that analyzes IT-intensive workflow designs and business processes within an organization.

On December 21, 2020 (Jadi 1, 1399) Afghanistan was scheduled to implement a 10% VAT. It has been delayed one year by the pandemic. When it does implement, Afghanistan will have significant workflow …

Singapore’S Proposed Approach To Tackling Missing Trader Fraud, Vincent Ooi

Research Collection Yong Pung How School Of Law

In the Draft Goods and Services Tax (Amendment) Bill 2020 (the “Draft Bill”), Singapore proposes a new framework to deal with the problem of MTF. The approach is neatly summarised by a document released by the Singapore Ministry of Finance: “Annex: Proposed Changes to the Goods and Services Tax Act”, of which one point is of particular interest. The document states that the proposed legislative amendments will “allow the Comptroller of GST to deny a GST-registered business’ input GST claim, if the business knew or should have known that his purchase was part of or connected with a fraudulent arrangement. …

Covid-19 And Us Tax Policy: What Needs To Change?, Reuven Avi-Yonah

Articles

The COVID-19 Pandemic already feels like a historical turning point akin to Word Wars I and II and the Great Depression. It may signal the end of the second period of globalization (1980-2020) and a change in the relative positions of the US and China. It could also lead in the US to significant changes in tax policy designed to bolster the social safety net which was revealed as very porous during the pandemic. In what follows I will first discuss some short-term effects of the pandemic and then some potential longer-term effects on US tax policy.

Uk & Ksa Vats: A Cutting-Edge Proposal – Mini-Blockchain And Vatcoin, Richard Thompson Ainsworth, Musaad Alwohaibi, Mike Cheetham

Faculty Scholarship

This paper develops, extends, and clarifies themes introduced in five prior papers dealing with blockchain, and VATCoin in the context of both (a) the new VATs in the Gulf Cooperation Council (GCC), and (b) the mature VATs in the EU. Five additional papers on VAT technology advances in Fiji, with blockchain and VATCoin applications to New Zealand’s approach to online sales platforms (the Netlix Tax) are similarly referenced and extended. The GCC VAT papers were exploratory. For the most part, they were composed before any GCC jurisdiction had implemented a VAT, and in three instances even before the GCC Framework …

Data First, Tax Next: How Fiji’S Technology Can Improve New Zealand’S 'Netflix Tax' (Part 2), Richard Thompson Ainsworth

Faculty Scholarship

This is the second in a four-part series addressing VAT/GST avoidance schemes involving remote sales of services. These schemes have been growing in importance. The IMF reports that the services component of cross-border trade has been on the rise for fifty-years or more, making the Internet a serious threat to revenue. Technology has accelerated tax avoidance.

Statutory draftsmen in New Zealand have looked at this problem directly with what has been called the Netflix Tax. Technologist in Fiji have been struggling with similar problems and have developed technology-based security systems that would seem to address remote sales of services more …

Data First, Tax Next: How Fiji’S Technology Can Improve New Zealand’S 'Netflix Tax' (Part 1), Richard Thompson Ainsworth

Faculty Scholarship

Over the past decade the VAT in the South Pacific has been changing. More change is coming. Change is needed in both the larger economies (Australia and New Zealand) and the smaller ones (the Pacific Island Countries or PICs). The changes we see currently are propelled by cross-border remote sales of services and low-value goods.

The government response in the South Pacific is not uniform. The larger economies have relied on statutory remedies; the smaller economies are turning to technology. The larger economies are crafting complex, extra-territorial compliance provisions targeting remote sellers. The smaller economies are mandating secure digital invoices, …

Digital Taxation Lessons From Wayfair And The U.S. States’ Responses, Walter Hellerstein, Jeffrey Owens, Christina Dimitropoulou

Scholarly Works

This article provides a detailed and structured synthesis of the discussion that took place in the context of the "fireside chat" event held by the WU Global Tax Policy Center at the Institute of Austrian and International Tax Law on December 17, 2018, at which Hellerstein was the guest speaker. The event was one of the initiatives of the Digital Economy Tax Network, a multi-stakeholder forum, which organized a workshop on the VAT/goods and services tax and the digital economy December 17-18, 2018, in Vienna. In this article, the authors examine the lessons that the U.S. Supreme Court's Wayfair decision …

Cloudy With A Chance Of Taxation, Orly Mazur, Rifat Azam

Faculty Journal Articles and Book Chapters

The growth of the digital economy, and, in particular, cloud computing, has put a significant strain on sales taxation and other consumption tax systems. The borderless, anonymous, and digital nature of cloud computing raises questions about the paradigm used to determine the character of the transaction and the location where consumption, and therefore, taxation occurs. From an American perspective, the effective resolution of these issues continues to grow in importance in light of the recent U.S. Supreme Court decision in South Dakota v. Wayfair and the growing number of U.S. businesses transacting overseas in jurisdictions that impose value-added taxes (VATs). …

Blockchain, Bitcoin, And Vat In The Gcc: The Missing Trader Example, Richard Thompson Ainsworth, Musaad Alwohaibi

Faculty Scholarship

Blockchain is coming to tax administration and will cause fundamental change. This article considers the potential for blockchain technology as it applies to the introduction of a value added tax in the Gulf Cooperation Council.

Blockchain technology disrupts centralized ledgers. Blockchain improves efficiency, security and transparency. Perhaps no centralized ledger system presents more challenges than that of the modern tax administration. The central data storage system of a modern tax authority contains all return, payment, and audit activity for all taxpayers arranged tax-by-tax for three years or longer periods of time.

It is likely that blockchain will come first to …

Trump & Vat: Nafta, Trade Barriers, And Retaliatory Tariffs, Richard Thompson Ainsworth

Faculty Scholarship

During the first presidential debate President-elect Donald J. Trump argued that the value added tax (VAT) operated as a trade barrier to American business everywhere. He particularly pointed to the North American Free Trade Agreement (NAFTA). Mexico was a special concern. China was also a concern, but in this instance Trump was troubled both by China’s VAT and by China’s alleged currency manipulation.

This paper can only consider the VAT aspect of Trump’s trade policy. There appears to be some confusion about the operation of the VAT, particularly the border adjustment mechanism, and how US tariffs could “level the playing …

Gcc Vat: The Intra-Gulf Trade Problem, Richard Thompson Ainsworth, Musaad Alwohaibi

Faculty Scholarship

It seems reasonably clear that by January 1, 2018 events will be set in motion for the adoption of a community-wide 5% value added tax (VAT) in the six Member States of the Gulf Cooperation Council (GCC).

The GCC’s Framework VAT document is expected to be published by the end of October 2016. One of the clearest, consistently placed observations is that the Arabian VATs will be destination-based and modeled on a European credit-invoice design. Intra-Gulf business-to-business (B2B) transactions will be effectively zero-rated by the supplier, and the buyer’s VAT will be directed to the destination jurisdiction. It is not …

Sales Suppression: The International Dimension, Richard Thompson Ainsworth

Faculty Scholarship

Sales transaction taxes are highly susceptible to technology fraud, which is an inevitable result of today’s widespread reliance on technology to document taxed transactions. Technology can be (and is) manipulated to defeat the collection of these taxes. Both the U.S. retail sales tax (RST) and the European value added tax (VAT) are vulnerable to technology-based fraud. This Article concerns sales suppression — intentionally not recording sales — in the RST, and at the final stage of the VAT, the retail stage, when tax is collected from final consumers.

The modern electronic cash register (ECR)/point of sale (POS) system is vulnerable …

Vatcoin: The Gcc's Cryptotaxcurrency, Richard Thompson Ainsworth, Musaad Alwohaibi, Mike Cheetham

Faculty Scholarship

Bitcoin is the world’s first peer-to-peer cryptocurrency. VATCoin is similar, but it is used in tax compliance. Both Bitcoin and VATCoin are distributive ledger applications built upon blockchain technology. Bitcoin’s ledger is public; VATCoin’s is private. If adopted, VATCoin could well become the world’s first government-mandated cryptotaxcurrency. Unlike Bitcoin, VATCoin will not be a speculative currency. It is always fixed to the home currency.

This paper proposes that the Gulf Cooperation Council (GCC) adopt VATCoin in its VAT Framework. The GCC is expected to have multiple 5% VATs in place by January 1, 2018. There is an ample amount of …

Vat In The Gcc - Missing Trader Frauds, Richard Thompson Ainsworth, Musaad Alwohaibi

Faculty Scholarship

All VATs are susceptible to missing trader (MT) fraud. VATs adopted in an economic community are particularly more susceptible. The EU, for example, loses in excess of €100b annually to this fraud. Given the anticipated adoption of a European-style credit-invoice VAT in the GCC by January 1, 2018, this paper offers a technology-based solution involving the real-time tracking of taxable transactions with centrally collected (securely encrypted) data flows that are risk-analyzed by artificial intelligence (AI).

Constructive Unilateralism: U.S. Leadership And International Taxation, Reuven S. Avi-Yonah

Articles

In recent years, various U.S. international tax proposals have been advanced on the basis that we should follow the lead of our major trading partners. For example, it has been argued that we should adopt a "territorial" tax system (really, an exemption for dividends by controlled subsidiaries of U.S. multinationals) because most of our trading partners have done so. Other voices have called for the United States to adopt a "patent box" because the United Kingdom and other EU jurisdictions have one.

In accordance with Directive 2003/87/EC of October 13, 2003, trade in greenhouse gas emissions commenced in the European Union (EU) on January 1, 2005. The EU-Emissions Trading System (EU-ETS) was born.

The EU has a Value Added Tax (VAT). VAT is a transaction-based levy on all trade in goods and services. Each Member State has a VAT as a condition of membership. Until January 3, 2017 transactions in CO2 permits are taxed as services. After this date they are exempt as financial instruments.

This change in VAT treatment of CO2 permits is directly attributable to rampant fraud in the market. …
