A Core Proposal For Budget Caring - Will The E.U. Adopt A Progressive Corporate Tax?, Domenico Imparato, Reuven S. Avi-Yonah

Articles

On 16 July 2025, the European Commission unveiled its proposed EU budget for the 2028–2034 period, representing a nearly EUR two trillion fiscal commitment for the bloc’s taxpayers – both individual and corporate. As leaked by some media outlets in the days leading up to the official announcement, the EU budget would introduce a new mechanism known as the ‘Corporate Resource for Europe’ (CORE). In the Commission’s proposal, CORE is described as a ‘financial contribution’ from the corporate sector, intended to become part of the European Union’s system of own resources. In practical terms, however, it would function as a …

Defining The Field Of Law And Macroeconomics: A Framework From International Monetary Law, Nikita Aggarwal, Adam Feibelman

Articles

This Article proposes an analytical framework for defining the contours of the emerging field of law and macroeconomics drawing on the International Monetary Fund's principle of "macro-criticality." Such a framework can help steer scholarly debate toward a clearer understanding of the relationship between law and the economy and inform policymaking within that domain. In its native context, the macro-criticality principle limits the IMF's jurisdiction to policy areas that are critical for member countries' domestic and external stability. The IMF's approach distinguishes between a core set of macrocritical policies and other non-core policies that are contextually macrocritical. Over time, the IMF …

Should Tax-Free Triangular Mergers Be Eliminated?, Reuven Avi-Yonah

Articles

The tax advantages of reverse triangular mergers under section 368(a)(2)(E) are well known. They enable the acquiring corporation (P) to use up to 60 percent cash consideration to acquire the stock of target (T) through a merger with a controlled subsidiary (S), with T surviving. This amount of boot is higher than what is allowed under a B or C reorganization. Because it is a triangular merger, it avoids exposing the assets of P to the liabilities of T (unlike a direct merger), and because it is equivalent to a stock acquisition, it avoids having to transfer assets, which is …

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 …

Deglobalization, Tax Competition, And The Potential Revival Of The Welfare State, Reuven S. Avi-Yonah, Doron Narotzki

Articles

Before 1980 the world was relatively closed. There were significant barriers to cross-border trade and investment in the form of tariffs and exchange controls. Martin Feldstein, former President Reagan’s chief economic adviser, coauthored an article in 1979 that showed that investment in the U.S. economy was about equal to U.S. savings, so the United States could manage without any foreign direct or portfolio investment.

Why Did The Irs Restart Transfer Pricing Litigation?, Reuven S. Avi-Yonah

Articles

In his excellent recent article on Coca-Cola’s appeal of its transfer pricing defeat in the Tax Court, Tax Notes contributing editor Ryan Finley explains that Coca-Cola’s main argument is based on the idea that “the IRS led the company into an ambush.” In 1996 the IRS entered into a closing agreement with Coca-Cola that provided that for the 1987 through 1995 tax years, the division of profits between Coca-Cola and its foreign “supply points” (the subsidiaries responsible for mixing the secret formula) would be based on a 10 percent return to the subsidiary and that any profit above that would …

Should The States Return To Worldwide Combined Reporting?, Reuven S. Avi-Yonah

Articles

On February 20 the Institute on Taxation and Economic Policy (ITEP) released a report on the revenue implications of states adopting worldwide combined reporting (WWCR). WWCR refers to a method of taxation that several states (for example, California) applied from the 1970s to the 1990s. Under WWCR, the state takes the entire worldwide profit of a multinational operating in the state and multiplies it by a formula that traditionally combines payroll, tangible assets, and sales in the state divided by worldwide payroll, assets, and sales. The result is the amount of profit taxable in that state.

Is The Utpr Extraterritorial Or Discriminatory?, Reuven S. Avi-Yonah

Articles

On January 20 President Trump issued two executive orders on international tax. The first order rejected the OECD’s two-pillar project, stating: The OECD Global Tax Deal supported under the prior administration not only allows extraterritorial jurisdiction over American income but also limits our Nation’s ability to enact tax policies that serve the interests of American businesses and workers. Because of the Global Tax Deal and other discriminatory foreign tax practices, American companies may face retaliatory international tax regimes if the United States does not comply with foreign tax policy objectives. This memorandum recaptures our Nation’s sovereignty and economic competitiveness by …

Esg Irony: Why Corporate Tax Avoidance Must Be Considered, Reuven S. Avi-Yonah

Articles

Environmental, social, and governance (ESG) investing has been the focus of major attention in corporate law. Many writers praised ESG as the future of corporate governance. The push for ESG comes from the belief that the government is incapable of fulfilling its responsibility of achieving social and environmental goals, and that corporations are frequently in the best position to help. ESG investing has been significantly bolstered by large asset management institutions like BlackRock Group, State Street Global Advisors, and Vanguard Group. The “Big Three” own large stakes in most public corporations, which they have been pushing to address ESG issues.

Tax Experience Isn’T Everything: A Tale Of Two Justices., Reuven S. Avi-Yonah

Articles

Any student of federal income taxation is familiar with a series of important Supreme Court tax decisions written by Justice Harry Blackmun (associate justice, 1970-1994). They would also know of three important decisions written by his contemporary, Justice Thurgood Marshall (associate justice, 1967-1991). It is interesting to compare the two, because Blackmun was the only recent justice with extensive tax practice experience, whereas Marshall had none. Yet, most of Blackmun’s tax opinions were wrong while Marshall’s opinions were right.

Should Country-By-Country Reporting Be Public?, Reuven S. Avi-Yonah

Articles

Under action 13 of the base erosion and profit shifting project, large multinational enterprises are obligated to file country-by-country reports with tax authorities. As of April 2024, over 80 countries have adopted a multilateral agreement on exchanging CbC reports. The United States has not adopted the multilateral agreement, but regulations require U.S.-based MNEs to file these reports with the IRS, which can then exchange them with other countries under tax treaties.

Tax In Law Schools, Michael Hatfield

Articles

At the 2023 Association of American Law Schools Tax Section meeting, professors discussed their impressions of a decline in the number of JD students studying tax. Their impressions were consistent with declines that have been documented in similar fields. Between 2011 and 2021, U.S. accounting programs saw an 18% drop in students, while new CPA candidates declined 39% from 2010 to 2022. In the United Kingdom, the number of law schools that teach tax has diminished by 43% since 2002. This Article examines tax education in 40 U.S. law schools, focusing on course offerings and enrollment trends from 2012 to …

Three Implications Of Moore., Reuven S. Avi-Yonah

Articles

In his majority opinion in Moore, Justice Brett Kavanaugh listed several provisions of the code that could be subject to a constitutional challenge if realization were a constitutional requirement, as suggested by Justices Amy Coney Barrett, Samuel A. Alito Jr., Clarence Thomas, and Neil M. Gorsuch. Kavanaugh wrote: In short, the Moores cannot meaningfully distinguish the [mandatory repatriation tax] from similar taxes such as taxes on partnerships, on S corporations, and on subpart F income. The upshot is that the Moores’ argument, taken to its logical conclusion, could render vast swaths of the Internal Revenue Code unconstitutional. See, e.g., 26 …

Delay, Politics, And Expertise In Oira Tax Review, Kristin E. Hickman, Bridget C.E. Dooling

Articles

The opening months of the second Trump administration have featured a wide range of changes to federal policy accomplished through presidential  executive orders. Among those changes, a lesser-known shift is the reinstatement of centralized review of tax regulations by the Office of Information of Regulatory Affairs (OIRA).

For many years, most tax regulations were exempt from OIRA review. That changed in the first Trump administration when the Treasury Department (Treasury) and OIRA signed a memorandum of agreement bringing more tax regulations within OIRA’s oversight sphere. In the Biden administration, Treasury and OIRA reversed course, this time clearly and unequivocally exempting …

Should Congress Reform The Accumulated Earnings Tax?, Reuven S. Avi-Yonah

Articles

In this installment of Reflections With Reuven Avi-Yonah, Avi-Yonah explains why the shifting landscape of the corporate tax rate requires congressional intervention. The Tax Cuts and Jobs Act 2017 permanently cut the corporate tax rate from 35 percent to 21 percent, and the Republican victory in the 2024 presidential election means that the rate is unlikely to be raised in the next four years. This means that there is, once again, a large disparity between the top individual tax rate of 37 percent (scheduled to increase to 39.6 percent in 2026 unless Congress acts) and the corporate rate. The corporate …

Should Harvard And Other Large Nonprofits Be Taxed?, Reuven S. Avi-Yonah

Articles

In this installment of Reflections With Reuven Avi-Yonah, Avi-Yonah examines justifications for exempting Harvard University and other large nonprofits from tax and argues that treating those organizations like large C corporations would not be such a bad thing. The proposal to subject large university endowment investment income to the corporate tax rate of 21 percent instead of the current 1.4 percent rate has engendered significant debate. More recently, President Trump’s threat to strip Harvard University of its tax-exempt status and treat it as a taxable corporation has likewise been controversial. In their recent Tax Notes article, Harvey Dale, Daniel Hemel, …

Can Side By Side Work?, Reuven S. Avi-Yonah

Articles

On June 26 Treasury Secretary Scott Bessent announced that a compromise had been reached between the United States and the rest of the G7 (Canada, France, Germany, Italy, Japan, and the United Kingdom), providing that pillar 2 of the OECD’s two-pillar global tax reform project will not apply to U.S. multinationals. As a result, proposed section 899, which would have imposed retaliatory taxation on corporations from countries that apply pillar 2 (and specifically the undertaxed profits rule) to U.S.-based multinationals, was removed from the One Big Beautiful Bill Act.

The Irs Approach To Periodic Adjustments: Losing Bet Or Royal Flush?, Jeffery M. Kadet, Reuven S. Avi-Yonah, David G. Chamberlain, Stephen L. Curtis

Articles

In this article, the authors argue that GLAM 2025-001 is consistent with the terms and purposes of the commensurate with income provision, relevant legislative history, and applicable case law and that the IRS approach to commensurate with income enforcement is a valid application of discretion delegated by Congress to the Treasury under Loper Bright.

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

Articles

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

Periodic Adjustments And The Arm's Length Principle, Reuven S. Avi-Yonah

Articles

The Internal Revenue Service (IRS) recently issued AM 2025-001, whichrepresents a significant change in its interpretation of the periodic adjustment rules for transfers of intangibles within a multinational and forcost-sharing agreements.Arguably, this finally brings the IRS into compliancewith the “commensurate with income” language added to Code Sec. 482 in1986.

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 …

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 …

Facebook Decision Enables Irs To Seek Cwi Enforcement Against Meta, Stephen L. Curtis, Reuven S. Avi-Yonah, David G. Chamberlain

Articles

In this report, the authors explain how the Tax Court’s recent decision in the Facebook transfer pricing case — although widely viewed as a victory for the taxpayer, Meta Inc. — could instead be a Pyrrhic victory because it enables the IRS to pursue a potentially substantial periodic adjustment against the company. The views expressed in this report are solely the authors’ and do not necessarily reflect those of any other person or institution. On May 22 the Tax Court issued its opinion in Facebook. This was the third case, after Amazon and Veritas, in which the IRS tried to …

Boden Lecture: Taxation Of Autonomous Artificial Intelligence, Reuven S. Avi-Yonah, Lucas Brasil Salama, Herbert Snitz, W. Robert Thomas

Articles

This Article proposes that tax can be a useful supplement to other measures to regulate Autonomous Artificial Intelligence (AAI) and limit its potential harmful effects. This proposal differs from command-and-control regulation of AAI along the lines of European Union legislation that may unduly limit the development of AAI. It also differs from existing proposals to tax AAI to generate revenue to help workers displaced by AAI programs, or to tax the data used by AAI The proposal is based on granting AAI programs like ChatGPT separate legal personhood, like corporate personhood, while incentivizing or requiring their corporate owner to place …

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.

The Perils Of Pseudo-Textualism, Reuven S. Avi-Yonah

Articles

How much freedom does the IRS have to interpret the code?

In recent years, the Supreme Court and lower courts have put significant barriers in front of the IRS’s ability to interpret the code as it wishes. The question is to what extent the IRS can live with the barriers of textualism, nondeference, the major questions doctrine, nondelegation, and the Administrative Procedure Act. Of these, textualism seems to be the most problematic because it is the hardest to fix. The major questions doctrine rarely applies to statutory tax cases. Nondeference based on Loper Bright can be restricted by Congress adding …
