This webinar will address the impact of new IRC Section 951B, Amounts included in gross income of foreign-controlled United States shareholders, added by the One Big Beautiful Bill Act (OBBBA), and the restoration of Section 958(b)(4) by the OBBBA. Our panel of veteran international tax practitioners will explain which U.S. shareholders and foreign corporations are impacted, the downward attribution rules, and reporting requirements for U.S. persons subject to these OBBBA provisions.
Description
The OBBBA added Section 951B, expanding the reach of the anti-deferral regime to foreign controlled U.S. shareholders (FCUSS) of foreign-controlled foreign corporations (FCFCs). At the same time, Section 958(b)(4), which prevented downward attribution of stock owned by foreign investors to a U.S. person, has been reinstated.
A FCUSS is a U.S. person owning more than 10% of the vote or value of a foreign corporation whose structure includes an FCFC.
A FCFC is a foreign corporation, other than a CFC, that is controlled by foreign persons owning more than 50% of the vote or value of a foreign corporation.
These modifications under the OBBBA will subject more entities to Subpart F and GILTI inclusions. Along with CFC taxation, these entities could be subject to additional reporting requirements, including PFIC and Form 5471 reporting obligations.
Listen as our panel of international tax advisers walks you through the recent changes OBBBA made to downward attribution rules and the corresponding compliance and reporting requirements.
