Pro Rata Share of Subpart F Income, Tested Income, or Tested Loss
Key claim: The IRS is proposing rules that would change how U.S. owners of controlled foreign corporations calculate their share of those companies’ Subpart F income and tested income or tested loss for current U.S. tax.
Abstract
(Proposed Rule · Treasury Department, Internal Revenue Service) This document contains proposed regulations relating to the determination of a United States shareholder’s pro rata share of subpart F income, tested income, or tested loss of a controlled foreign corporation. The proposed regulations would affect shareholders of foreign corporations, including United States shareholders of controlled foreign corporations.
Why this matters
Pro rata share rules determine how much CFC income each U.S. shareholder must currently include under Subpart F and GILTI, directly affecting U.S. tax liability for multinationals and their investors. Changes to the allocation methodology can shift which shareholders bear tax on which slices of foreign earnings, even when total CFC income is unchanged. The proposed rule is technical but consequential for international tax planning and compliance.
