144 S.Ct. 1680
U.S.2024Background
- Charles and Kathleen Moore owned a 13% stake in KisanKraft, an American‑controlled foreign corporation that earned substantial undistributed profits from 2006–2017.
- The 2017 Tax Cuts and Jobs Act imposed a one‑time Mandatory Repatriation Tax (MRT) under 26 U.S.C. §965, attributing certain accumulated, undistributed corporate income to U.S. shareholders and taxing their pro rata shares (8–15.5% rates); the Moores paid $14,729 and sued for refund.
- The Moores challenged the MRT as an unconstitutional unapportioned direct tax in violation of the Direct Tax Clause (they argued the MRT taxed property/stock value because they had not realized income) and raised a due process retroactivity claim (rejected below; certiorari was limited to the Direct Tax issue).
- The Government defended the MRT as a tax on income (not property) and invoked longstanding congressional practice and precedent permitting attribution of an entity’s realized undistributed income to owners/partners for tax purposes (e.g., subpart F and other pass‑through regimes).
- The Supreme Court affirmed the Ninth Circuit: MRT is an income tax that need not be apportioned because Congress may attribute an entity’s realized and undistributed income to its shareholders and tax them on their pro rata shares; the opinion emphasized precedent and longstanding practice but limited the holding to pass‑through attribution and declined to decide whether realization is constitutionally required in all contexts.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the MRT is an unapportioned direct tax (Direct Tax Clause) because it taxes shareholders on undistributed corporate earnings they never "realized." | Moore: MRT is effectively a property/stock tax (unrealized gains); realization is required for Sixteenth Amendment income taxation, so MRT must be apportioned. | U.S.: MRT taxes income—specifically income realized by the corporation and attributed to shareholders—so it is an indirect income tax and need not be apportioned. | Held: MRT is an income tax; Congress may attribute an entity’s realized, undistributed income to shareholders and tax their pro rata shares without apportionment. |
| Whether precedent (and congressional practice) permits attributing undistributed corporate/partnership income to owners for tax purposes. | Moore: Prior cases (notably Eisner v. Macomber) and differences between entities (partnerships, S‑corp elections, control thresholds) distinguish MRT from longstanding practices. | U.S.: Precedent (Burk‑Waggoner, Burnet, Heiner, Helvering) and long congressional practice (partnership taxation, S corporations, subpart F) allow attribution; MRT fits that tradition. | Held: The Court read precedent and practice as authorizing attribution of undistributed entity income to owners; the Moores’ attempted distinctions fail. |
| Whether realization as a constitutional requirement must be decided (i.e., can Congress tax unrealized gains). | Moore: Realization is constitutionally required for income and MRT taxes unrealized shareholder gains. | U.S.: Contends realization is not constitutionally required in all cases, but MRT taxes corporate realized income attributed to shareholders. | Held: Court did not resolve whether realization is a constitutional requirement in general; decision is narrow and rests on attribution of entity’s realized income. |
| Limits on attribution (due process/arbitrariness; double taxation; scope) | Moore: Attribution must respect limits (ownership, control, temporal nexus); MRT lacks those safeguards. | U.S.: Attribution doctrine and subpart F features (e.g., control thresholds) provide constitutional boundaries; due process prevents arbitrary attribution. | Held: Court recognized due process limits and disclaimed authority to permit double taxation of the same undistributed income; endorsed attribution in the MRT context but limited ruling to pass‑through situations. |
