This webinar will explore the scope and potential impact of the changes to the downward attribution rules and the new IRC Section 951B. Our panel of seasoned international tax practitioners will explain which U.S. shareholders and foreign corporations may be affected and how to prepare ahead of the effective date.

Description

The One Big Beautiful Bill Act (OBBBA) reinstated, with modifications, Section 958(b)(4), which previously prevented downward attribution of stock owned by foreign persons to U.S. persons. Simultaneously, it introduced Section 951B—a new anti-deferral regime that extends Controlled Foreign Corporation (CFC)-like inclusion rules, with certain modifications, to “foreign-controlled United States shareholders” (FCUSS) of “foreign-controlled foreign corporations” (FCFCs), even if these entities do not meet the traditional definition of a CFC.

U.S. persons subject to Section 951B must comply with a parallel set of rules similar to those governing traditional CFCs. This includes information reporting (e.g., Form 5471) and income inclusion requirements, with specific adjustments for the foreign-controlled context.

Listen as our panel of international tax advisers walks through the recent changes introduced by OBBBA, focusing on downward attribution rules and the resulting compliance and reporting requirements.
