The Indirect Taxes, Conor Clarke, Ari Glogower

Scholarship@WashULaw

Article I of the Constitution empowers Congress to “lay and collect Taxes, Duties, Imposts and Excises.” It is arguably Congress’s most important power. A government’s first task is to fund itself, and the absence of an enforceable funding mechanism under the Articles of Confederation was a primary reason for the Constitution in the first place. Yet scholarly and judicial attention has focused mostly on the term “taxes” (and specifically what constitutes a “direct tax” that must be apportioned) while largely overlooking the three terms that follow—the duties, imposts, and excises that are collectively known as the “indirect taxes.” 

While poorly …

Analysis Of The Impacts Of Propositions 41 And 42 On California Public Finance, David Gamage, Brian D. Galle, Darien Shanske

Faculty Publications

This memorandum discusses the possible collateral damage that Propositions 41 and 42 (on the ballot in California on November 3, 2026) might cause.  The two propositions were concocted very quickly by billionaires in order to trick voters that will vote for Proposition 40 (the billionaire tax) also to vote for these propositions that are designed to undermine the billionaire tax.

The basic trick is that these propositions have plausible seeming veneers but hide a poison pill that aims to frustrate the functioning of the billionaire tax.  The veneers are “plausible seeming” because they address problems that are not problems.  For …

Aligning Reparations And Taxation, Katherine Pratt

William & Mary Journal of Race, Gender, and Social Justice

Rehabilitative reparation remedies advance the important normative goals of intergenerational restorative justice and racial reconciliation. This Article fills a gap in the reparations literature by exploring a critical missing piece of reparations—nontaxation of reparation remedies. Historical examples of reparation remedies show how, in the past, a patchwork of tax rules prevented taxation of reparations and advanced the rehabilitative goals of reparation remedies and procedural fairness in tax administration. Conversely, contemporary examples show how current tax law taxes the receipt of reparation remedies, thereby undermining the rehabilitative goals of reparations and procedural fairness.

This Article proposes a new statutory tax exclusion …

Inequality As Market Failure, Erick J. Sam

William & Mary Bill of Rights Journal

This Article explores economic, philosophical, and legal relationships between economic inequality and market failure, and it draws on these linkages to develop an innovative normative justification and alternative constitutional basis for a levy on wealth.

The Article’s central analytic result is that several general mechanisms responsible for common market failures can also systematically produce economic inequalities whenever preferences against extreme inequality are fairly widespread. Because these mechanisms satisfy both the ‘process-based’ and ‘outcome-based’ criteria of market failure, redistributive transfers designed to reduce these inequalities would be normatively justified under the widely accepted market failure theory of government action. On this …

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 …

Foreword: The Constitution And Public Finance—Why Now And Why Ever?, Conor Clarke, Eric Kubo

Scholarship@WashULaw

This paper introduces the Washington University Law Review’s 2026 symposium issue on “Taxing, Spending, and the Constitution.” We situate the symposium’s ten papers within three interconnected developments in public finance law: the Supreme Court’s recent decision on the Sixteenth Amendment in Moore v. United States; the Trump Administration’s assertions of executive control over appropriated funds; and the use of emergency and trade statutes to justify sweeping tariff authority.

We also step back to ask why constitutional issues in public finance—long treated as a technical backwater—have become such a central site of doctrinal and political conflict. We offer several explanations beyond …

Tariffs And The Progressive Fiscal Constitution, Lawrence J. Liu, Alex Zhang

Scholarship@WashULaw

For more than a century, progressive taxation has constituted the American fiscal state. A resurgent and expanding tariff regime, however, threatens that commitment to progressive distribution. Given the ongoing popularity of tariffs, this Article examines how they might be designed and administered in a way that mitigates their regressive distributive impact. The Article thus develops and assesses proposals to (1) vary tariff burdens in accordance with the consumption of imported goods, (2) reduce income- or payroll-tax burdens on lower-income households, and (3) earmark tariff revenue for specified spending programs. Although none is perfect, we seek to articulate possibilities and highlight …

A New View Of Taxation, Christopher H. Hanna

Faculty Journal Articles and Book Chapters

Tax scholars have made a number of breakthrough discoveries in tax law going back to at least Thomas Hobbes and his observations on a consumption tax almost 400 years ago. In more recent times, in the 1970 and 1980s, a number of tax law scholars made very important contributions in understanding the similarities and differences between an income tax, a consumption tax and a wage tax, as well as developing a greater understanding in a related area—the time value of money. It seems, however, that in the last 30 years or so, the only breakthrough or significant discovery in tax …

The Federal Income Tax Consequences Of Property Settlements In Common Law States And Under The Uniform Marriage And Divorce Act: A Proposal, Maine Law Review

Maine Law Review

Generally, during marriage, most of the property of husband and wife is held in the husband's name. Then, if there should be a divorce, the husband often finds himself required to transfer some of this property to his wife as a "property settlement." If the transferred property has appreciated in value while held by the husband, this appreciation may be treated as taxable income to the husband. Whether the appreciation is so treated depends on the marital property law of the taxpayer's domicile. In the United States, two different systems of marital property law have developed. Most states have evolved …

The Tax Home Doctrine: Fifty-Five Years Of Confusion, Carolyn Grahame Walker

Maine Law Review

Provisions of the Internal Revenue Code have always allowed taxpayers to deduct business expenses from their gross income before a personal income tax is imposed. Under certain circumstances, traveling expenses, such as amounts expended by taxpayers for travel fares, meals, and lodging, are deductible as business expenses. The United States Supreme Court has held that a taxpayer's traveling expenses must meet three conditions to be deductible under this section: the traveling expenses must be reasonable and necessary, directly related to the pursuit of business, and incurred while away from home. The third condition poses the most problems for taxpayers, the …

The Role Of Unrealized Gains And Borrowing In The Taxation Of The Rich, Edward Fox, Zachary Liscow

Law & Economics Working Papers

As deficits rise and concerns about tax avoidance by the rich increase, we study how unrealized gains and borrowing affect Americans’ income taxes. We have four main findings: First, measuring “economic income” as currently-taxed income plus new unrealized gains, the income tax base captures 60% of economic income of the top 1% of wealth-holders (and 71% adjusting for inflation) and the vast majority of income for lower wealth groups. Second, adjusting for unrealized gains substantially lessens the degree of progressivity in the income tax, although it remains largely progressive. Third, we quantify for the first time the amount of borrowing …

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

Marquette Law Review

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 …

Money Moves: Taxing The Wealthy At The State Level, David Gamage, Brian D. Galle, Darien Shanske

Faculty Publications

It's widely understood today that inequality is a major social problem that in turn contributes to other crises. By most accounts, tax systems are supposed to be our engines of equality. Yet in today’s United States, state and local tax systems mostly do the opposite: they take a greater percentage of the resources of the poor and middle class than of the rich.

Perhaps surprisingly, the traditional view among fiscal policy experts has been that this state of affairs is correct. In this standard account, only national governments should impose progressive or redistributive taxes. While acknowledging that there would be …

#Taxback? Prohibiting State Real Property Taxes On Land In Indian Country, Pippa Browde

Marquette Law Review

Land is a critical asset of Indian tribes. As tribes wrestle with how to create sustainable economies to support their sovereignty, the use and management of tribal land is integral. Taxation is a key component of economic development. This Article is about taxation of land within Indian country. It considers existing law that allows for state taxation of some land within Indian country. It makes a normative claim as to who the proper taxing sovereign should be based on tax policy principles and principles that support tribal self-governance and tribal sovereignty.

In Part II, this Article provides the background for …

Virtual Currency As Real Currency, Jeffrey A. Maine

Faculty Publications

Convertible virtual currency is increasingly equated with the notion of real currency. Indeed, the increased acceptance of virtual currency as a payment method among retailers and consumers, the evolution of new types of virtual currency that alleviate price volatility, and the recent expansion of foreign country initiatives confirm the strong trajectory toward virtual currency’s function as a transactional currency. Yet, the tax system continues to classify all forms of virtual currency as “property,” and not “currency,” which results in immediate taxation every time someone buys something with virtual currency. This Article argues that the adopted tax treatment of virtual currency …

Brief For Tax Law Professors As Amici Curiae In Support Of Petitioners In Learning Resources (No. 24-1287) And Respondents In V.O.S. Selection (No. 25-250), Conor Clarke, Jon Endean, Ari Glogower, Daniel J. Hemel

Scholarship@WashULaw

The Constitution gives Congress, and not the President, the authority to “lay and collect Taxes, Duties, Imposts, and Excises.” The Constitution also mandates that revenue measures begin in the House of Representatives, requires that such measures be geographically uniform, and prohibits the states from imposing import duties without congressional consent. Read together with Article I’s vesting of “all legislative Powers” in Congress and the familiar requirements of bicameralism and presentment, these provisions reflect a recurring constitutional commitment: Tariffs are national and legislative—and thus to be determined by a representative Congress.

History bolsters these textual commitments. State conflict over import duties …

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 …

Backing-Into Internal Revenue Code Section 338, Drew Erik Swenson

Maine Law Review

In recent years there has been an increasing incidence of corporate takeovers. Typically, the takeover begins with a purchasing corporation acquiring a controlling but less than 100% interest in the target corporation. Often, the partial ownership is merely a transitory step toward complete ownership, shortly after which the target is liquidated or merged into what is now the parent corporation. In other instances, the target retains its separate corporate existence within a parent/subsidiary relationship. The choice between termination and continued corporate existence is made only after a careful appraisal of the economic and tax consequences to the parent and the …

Tax As Hybrid Law: Borrowing And Convergences, Henry Ordower

All Faculty Scholarship

[This article argues that tax is a hybrid of civil and common law, public and private law, and is cross-disciplinary. It observes that tax law has become an all-purpose tool for legislators. It seeks to demonstrate how the U.S., a common law jurisdiction, has turned to civil law models for taxation while civil law jurisdictions and the European Union have sought common law models to combat tax avoidance. The ubiquity of tax and its public law influence on private law transactions, its cross disciplinary nature, and its deployment as a legislative tool to manage the economy make it a candidate …

Taxation's Limits, Luís C. Calderón Gómez

Northwestern University Law Review

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 …

The U.N. Framework Tax Convention: Can It Bridge The North-South Divide?, Assaf Harpaz

Scholarly Works

The United Nations recently concluded the second session of negotiations on terms of reference for a framework convention on international tax cooperation. The framework convention presents an opportunity to multilaterally address pressing global tax issues. Its goal is to “strengthen international tax cooperation and make it fully inclusive and more effective.” The extensively negotiated terms of reference make several substantive commitments, including the fair allocation of taxing rights; tax evasion and avoidance by high-net worth individuals; sustainable development; mutual administrative assistance in tax matters; tax-related illicit financial flows; and prevention and resolution of tax disputes. The ongoing multilateral effort brings …

Crypto Losses, Xuan-Thao Nguyen, Jeffrey A. Maine

Articles

The crypto industry has been hit hard with various market forces and scams, leaving investors with trillion-dollar losses in recent years. The appropriate tax treatment of such losses has yet to be fully examined, as there is scant guidance and a dearth of academic literature on the subject. This Article attempts to fill this gap by applying general tax principles to crypto losses and making several recommendations to improve the clarity and consistency of tax results. It explores various theories of crypto loss “realization” (including theft, abandonment, and worthlessness), highlighting where additional guidance is needed. And it considers appropriate legislative …

The Policy And Politics Of Alternative Minimum Taxes, David Gamage, Ari Glogower

Faculty Publications

This paper contributes to a literature offering qualified justifications for alternative minimum tax (AMT) structures. We conclude that there is a narrow case for justifying AMTs even from the social planner perspective and that the proposed Billionaire’s Minimum Income Tax satisfies that narrow case. Next, incorporating governance collective action problems and electoral political constraints, we conclude that these considerations support a broader case for justifying AMTs that potentially also supports both preference-disallowance AMTs and the new corporate alternative minimum tax enacted in 2022.

A Roadmap To Nil And Taxation, Doron Narotzki, Yariv Brauner

American University Business Law Review

The landscape of college sports has dramatically changed in recent years. What was once considered a place for amateur athletes pursuing education now partially mirrors, at least for some student-athletes, the structure and financial dynamics of professional leagues such as the NFL, NBA, and MLB. However, the collegiate sports ecosystem still remains distinct, shaped by unique regulatory frameworks governed by the NCAA. This article reviews and analyses the implications of these changes, and focuses on the tax considerations surrounding Name, Image, and Likeness (NIL) rights and how the evolving nature of college sports also presents certain tax implications, some of …

Charter Schools And Emos: Who's In Charge, Brendan Glynn

American University Business Law Review

Charter schools are a popular sight in the educational field today. For the IRS to consider a charter school a 501(c)(3) organization, nonprofit charter schools must be organized and operated exclusively for educational purposes, meaning purposes relating to the instruction of individuals to improve their capabilities. To be organized for educational purposes, the articles of the organization must limit the entity to educational purposes while also preventing the organization from engaging in substantial noneducational activities. To operate exclusively for educational purposes, an organization’s activities must be substantially in furtherance of educational purposes while also not substantially benefitting a private individual. …

Transaction-Specific Tax Reform In Three Steps: The Case Of Constructive Ownership, Thomas J. Brennan, David M. Schizer

Faculty Scholarship

Similar investments are often taxed differently, rendering our system less efficient and fair. In principle, fundamental reforms could solve this problem, but they face familiar obstacles. So instead of major surgery, Congress usually responds with a Band-Aid, denying favorable treatment to some transactions, while preserving it for others. These loophole-plugging rules have become a staple of tax reform in recent years. But unfortunately, they often are ineffective or even counterproductive. How can Congress do better? As a case study, we analyze Section 1260, which targets a tax-advantaged way to invest in hedge funds. This analysis is especially timely because a …
