Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Pat Brown, an International Tax Partner and Co-Leader of PwC’s Washington National Tax Services practice. Pat previously served as the US Treasury’s Deputy International Tax Counsel and has been a frequent guest on the podcast. Doug and Pat discuss the legislative and international tax implications of the 'One Big Beautiful Bill', including its procedural path through US Congress under budget reconciliation, and its implications for both domestic and cross-border taxpayers. They explore the bill’s temporary business provisions, including TCJA 'orphan' fixes, and the evolving treatment of research expenses, bonus depreciation, and interest deductions. A major focus is Section 899—dubbed the 'super BEAT'—which targets foreign digital services taxes (DSTs), diverted profits taxes (DPTs), and Pillar Two’s undertaxed profits rule (UTPR) with steep retaliatory measures. They also analyze the international negotiations around UTPR exemptions, the impact on treaty obligations, and the ongoing debate over treatment of US tax credits—particularly the R&D credit—under global minimum tax rules.
