• Following the June 26, 2025 G7–U.S. Treasury compromise, the U.S. Congress removed proposed IRC Section 899 retaliatory withholding surcharges (+5% to +20%) in exchange for Side-by-Side UTPR safe-harbour protections for U.S.-parented groups (Source: U.S. Department of the Treasury, 2025-06-26).
• Investment entities and sovereign wealth funds qualifying as Excluded Entities under GloBE Article 1.5 are subject to a 0% GloBE top-up tax floor, provided they are not consolidated line-by-line into a non-exempt MNE group (Source: OECD GloBE Commentary, 2026-09-18).
• OECD Pillar Two 15% Global Minimum Tax (GloBE, QDMTT, IIR & UTPR) (OECD-GLOBE-QDMTT) prints at 15.0% (Minimum Effective Tax Rate) under OECD/G20 Inclusive Framework supervision as of 2026-10-20.
