Mandatory Repatriation Tax Challenged: Potential Billions in Refunds for US Multinationals

The most recent filing in the significant tax case, Moore v. United States, has presented compelling arguments for the US Supreme Court to invalidate the mandatory repatriation tax. This outcome, according to observers, could potentially lead to billions in tax refunds for US multinationals.

Taxpayers Charles and Kathleen Moore have clarified their standpoint in their November 15 reply brief. They assert that an overturning of the mandatory repatriation tax wouldn’t spur budgetary chaos as critics suggest, but would remain limited in scope.

At the heart of the matter is the Moores’ request for a $14,729 tax refund on an Indian machine-tool company’s undistributed earnings. A key contention of this case is whether the IRS can tax the shareholders of a foreign corporation on the company’s income without a cash dividend or other distribution.

Until now, the word ‘realization’ has been a bone of contention between the taxpayers and the government in cases spanning the last century. The Moores argue that without actual cash distribution, shareholders haven’t ‘realized’ any income that can be suitably taxed under the 16th Amendment. The government, however, refutes that the Constitution necessitates a realization requirement, stressing only upon the need for economic gain or profit.

The Moore’s latest filing poses a potent challenge to the government’s interpretation of the landmark 1920 tax case, Eisner v. Macomber. They argue that by the same factors that rendered an attempt to impute a corporation’s income to its shareholders unconstitutional in the Macomber case, the mandatory repatriation tax should also be considered unconstitutional.

Addressing concerns that their argument applies only to cases involving stock dividends, the taxpayers posit that the Macomber Court necessitated engagement with the constitutional question pertaining to both stock dividends and the attribution of corporate earnings to shareholders.

In their brief, the Moores counter the government’s claim that attribution in corporations mirrors the process in partnerships. They highlight that Macomber had rejected similar assertions of likening shareholders to partners when they are not.

The Moores contend that their interpretation of Macomber wouldn’t invalidate any tax law provisions other than the mandatory repatriation tax. They assert that their approach wouldn’t affect Subpart F, partnership taxation, accrual accounting, original issue discount, and various anti-abuse rules.

The case, Moore v. United States,, continues to unfold with the latest reply brief filed on 15 November 2023.
