On Thursday, 7 March 2024, the Tax Subcommittee of the House Committee on Ways and Means held a hearing on the Organization for Economic Co-operation and Development (OECD) inclusive framework’s Pillar One project. The hearing marked Congress’ first public inquiry dedicated solely to Pillar One since the release of the draft Multilateral Convention to Implement Amount A of Pillar One (MLC) and the final Amount B report. The same Subcommittee examined both Pillar One and Pillar Two in a July 2023 hearing that featured then-Deputy Assistant Secretary for International Tax Affairs Michael Plowgian.

On 8 December 2023, Treasury and the IRS released Notice 2024-16 announcing their intent to issue proposed regulations addressing the treatment of basis under section 961(c) in certain inbound nonrecognition transactions in which a domestic corporation acquires the stock a controlled foreign corporation (CFC) from another CFC. These proposed regulations are in addition to the highly anticipated proposed previously taxed earnings and profits (PTEP) regulations expected this year. According to the Notice, the proposed regulations will provide that, in the case of certain “covered inbound transactions,” the domestic acquiring corporation’s adjusted basis in the acquired CFC stock (as determined under section 334(b) or 362(b)) will be determined as if the transferor CFC’s section 961(c) basis were adjusted basis.
