MOORE ET UX. v. UNITED STATES CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE NINTH CIRCUIT

No. 22–800. Argued December 5, 2023—Decided June 20, 2024 Congress generally taxes the income of American business entities in one of two ways. Some entities, such as S corporations and partnerships, are taxed on a pass-through basis, where the entity itself does not pay taxes. 26 U. S. C. §§1361–1362. Instead, the entity’s income is attributed to the shareholders or partners, who then pay taxes on that income even if the entity has not distributed any money or property to them. §§61(a)(12), 701, 1366(a)–(c). Other business entities do pay taxes directly on their income. Those entities’ shareholders ordinarily are not taxed on that income but are taxed when the entity distributes a dividend or when the shareholder sells shares. Congress treats American-controlled foreign corporations as pass- through entities. Subpart F of the Internal Revenue Code attributes income of those business entities to American shareholders and taxes those shareholders on that income. §§951–952. Subpart F, however, applies only to a small portion of the foreign corporation’s income, mostly passive income. In 2017, Congress passed the Tax Cuts and Jobs Act. As relevant here, Congress imposed a one-time, backward- looking, pass-through tax on some American shareholders of American-controlled foreign corporations to address the trillions of dollars of undistributed income that had been accumulated by those foreign corporations over the years. Known as the Mandatory Repatriation Tax, the tax imposed a rate from 8 to 15.5 percent on the pro rata shares of American shareholders. §§965(a)(1), (c), (d). In this case, petitioners Charles and Kathleen Moore invested in the American-controlled foreign corporation KisanKraft. From 2006 to 2017, KisanKraft generated a great deal of income but did not distribute that income to its American shareholders. At the end of the 2017 tax year, application of the new MRT resulted in a tax bill of 2 MOORE v. UNITED STATES

Syllabus

$14,729 on the Moores’ pro rata share of KisanKraft’s accumulated income from 2006 to 2017. The Moores paid the tax and then sued for a refund, claiming, among other things, that the MRT violated the Direct Tax Clause of the Constitution because, in their view, the MRT was an unapportioned direct tax on their shares of KisanKraft stock. The District Court dismissed the suit, and the Ninth Circuit affirmed. Held: The MRT—which attributes the realized and undistributed income of an American-controlled foreign corporation to the entity’s American shareholders, and then taxes the American shareholders on their portions of that income—does not exceed Congress’s constitutional authority. Pp. 5–24. (a) Article I of the Constitution affords Congress broad power to lay and collect taxes. That power includes direct taxes—those imposed on persons or property—and indirect taxes—those imposed on activities or transactions. Direct taxes must be apportioned among the States according to each State’s population, while indirect taxes are permitted without apportionment but must “be uniform throughout the United States,” §8, cl. 1. Taxes on income are indirect taxes, and the Sixteenth Amendment con
