Transforming Tax Expenditures, Sloan G. Speck

Publications

For decades, reformers have advocated the repeal of tax expenditures--disguised government spending through special preferences in the Internal Revenue Code. And yet, tax expenditures persist, impairing federal tax receipts by more than $1.8 trillion in 2024. This Article introduces a novel mechanism for tax expenditure reform. To the extent that direct statutory repeal proves impossible or impractical, lawmakers can achieve an equivalent result through a strategy of legislative anti-repeal. By radically expanding a tax expenditure's legal scope, then adjusting progressive income tax rates to account for revenue loss and distributional considerations, lawmakers can effectively eliminate tax expenditures from the tax …

Are Nonprofit Tax Exemptions And Deductions “Federal Financial Assistance”? Should They Be?, Lloyd Hitoshi Mayer

Journal Articles

Two recent federal court decisions have reignited the debate over whether “Federal financial assistance” as used in four federal anti-discrimination statutes includes the tax benefits enjoyed by most nonprofit organizations. Both courts concluded that it does. While an appellate court reversed one decision, and the other case settled without appellate review, these holdings create significant uncertainty. And this uncertainty affects the more than 1.8 million tax-exempt nonprofits, many if not most of which do not receive federal financial assistance through other channels and so could safely conclude these statutes do not reach them, absent these decisions.

This Article first considers …

Spending Clause Standing, Edward Webre Plaut

Michigan Law Review

The Biden Administration’s American Rescue Plan Act allotted almost $220 billion to state, local, and tribal governments to help combat the COVID-19 pandemic. This money, the Coronavirus State and Local Fiscal Recovery Fund, gave recipients wide spending discretion to address their struggling economies. But the legislation had one key limitation: Recipients could not use the money to “directly or indirectly” cut their taxes. If a recipient violated this “Offset Provision,” the Department of the Treasury might recoup the funds.

Nearly two-dozen states alleged that the Offset Provision was unduly coercive and ambiguous, violating the Spending Clause. However, with no threatened …

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 …

The Original Function Of Tax Apportionment, Conor Clarke, Peter J. Wiedenbeck

Scholarship@WashULaw

The Constitution’s requirement that direct taxes be apportioned by state population is both confounding and important. At best, tax apportionment is regarded as reflecting the unique federalism concerns of the Founding; at worst, it is viewed as a tainted product of the constitutional compromise over slavery. And, in light of the Supreme Court’s decision in Moore v. United States (2024)—which refused to rule out that apportionment might be required for taxes on unrealized gains—tax apportionment is the subject of renewed legal and scholarly interest.

We consider one historical dimension of tax apportionment that has not been developed elsewhere: its original …

Moore Questions, Some Answers: Fixing The Personal Tax System Despite Constitutional Constraints, David Gamage, John R. Brooks, Edward J. Mccaffery

Faculty Scholarship

Moore v United States was expected to rule on the constitutional necessity of the tax-law realization requirement originating from Eisner v Macomber, a potential impediment to progressive tax reform efforts aimed at shutting down the planning techniques of Buy Borrow Die. The various opinions in Moore, however, provided no definitive answer to this core question, instead leaving many more questions. Amid the lingering uncertainty, we argue that various responses to the problem of wealthy Americans’ not needing to pay any taxes remain possible after Moore. An incremental, “mix-and-match” approach to progressive tax reform may best suit the …

The issue waswhether the treaty provided an independent basis for crediting a foreigntax 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 wasavailable, distinguishing Toulouse.Third, in Bruyea, the Court of Federal Claimsissued a broader opinion that allowed the credit.

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 …

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 …

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, …

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 …

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.

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 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.

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.

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.

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 …
