This course will provide tax advisers with a practical overview of Subpart F tax treatment of controlled foreign corporations (CFCs). The panel will detail in plain language specific areas of Subpart F, including the recent changes made by the One Big Beautiful Bill Act (OBBBA), the final and proposed regulations, and foreign information reporting requirements on Form 5471.
Faculty

Mr. Samtoy’s practice specializes in international tax compliance and consulting services, with a focus on individuals, closely-held businesses, and hedge funds. He has particular expertise in structuring and reporting foreign manufacturing arrangements and foreign holding companies, and is experienced in foreign asset disclosure requirements, as well as foreign trust and estate reporting.
Description
The Subpart F rules require U.S. shareholders of CFCs to treat certain types of income as taxable in the current year. These calculations have long presented challenges to tax advisers serving clients with CFC holdings. Most recently, OBBBA made significant changes to Subpart F inclusions. Under OBBBA, the income inclusion is pro-rated based on the time period the CFC shareholder held the stock. Prior to OBBBA, a shareholder's income inclusion was determined based on ownership on the last day of the CFC's year. Additional modifications impacting Subpart F inclusions, including the reinstatement of Section 958(b)(4) limiting downward attribution of stock and New 951B anti-deferral rules, were also added by OBBBA.
Continually updated legislation adds complexity to an already challenging regime. Tax advisers must also know whether the new rules create new filing obligations to avoid severe penalties for foreign information reporting noncompliance.
Listen as our authoritative panel of international tax practitioners reviews the Subpart F rules and provides a practical guide to the specific CFC ownership and reporting obligations.
