Moore v. United States
Headline: Back-tax on foreign corporate earnings upheld, allowing the Government to tax U.S. owners of closely held foreign companies on undistributed historic profits and reducing offshore tax avoidance opportunities.
Holding: The MRT—which attributes an American-controlled foreign corporation’s realized and undistributed income to its U.S. shareholders and taxes those shares—does not exceed Congress’s constitutional taxing power.
- Allows taxing U.S. owners on undistributed foreign corporate earnings.
- Affirms Congress can attribute undistributed corporate income to shareholders.
- Leaves open whether unrealized appreciation can be taxed without apportionment.
Summary
Background
Charles and Kathleen Moore invested $40,000 for a 13% stake in an American-controlled foreign company called KisanKraft. From 2006 to 2017 KisanKraft earned and kept large profits overseas. The 2017 Tax Cuts and Jobs Act imposed a one-time Mandatory Repatriation Tax (MRT) that attributed those realized but undistributed corporate earnings to American owners. The Moores were assessed about $14,729, paid it, and sued for a refund saying the tax was an unconstitutional unapportioned direct tax; lower courts dismissed their claim and the Ninth Circuit affirmed.
Reasoning
The Court framed the core question as whether Congress may attribute an entity’s realized and undistributed income to its shareholders and tax those shareholders without apportionment. The majority held yes. It explained that income taxes are indirect taxes that the Sixteenth Amendment allows without apportionment. The Court relied on a line of precedents saying Congress can tax either an entity or its owners on undistributed earnings (cases such as Burk-Waggoner, Burnet, Heiner, and Helvering) and on long-standing congressional practice including subpart F, S‑corporation rules, and partnership taxation. The Court distinguished Eisner v. Macomber and stressed its holding is narrow: it applies when Congress treats an entity as a pass-through and does not permit taxing both the entity and its owners on the same undistributed income. The Court also noted due-process limits on arbitrary attribution and expressly did not resolve whether realization is a constitutional requirement for all income taxes.
Real world impact
The decision lets the Government collect the MRT and affirms Congress’s authority to attribute and tax undistributed, realized income of pass-through entities to owners. U.S. owners of American-controlled foreign corporations are most directly affected. The ruling is limited in scope and leaves open related questions, including broader challenges about taxing unrealized appreciation.
Dissents or concurrances
Justice Jackson concurred, urging restraint and deference to Congress on tax matters. Justice Barrett concurred in the judgment but warned the question is complex and indicated different results might follow for widely held or domestic corporations. Justice Thomas dissented, arguing the Sixteenth Amendment requires realization and that the MRT is unconstitutional.
