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 and former US Treasury’s Associate International Tax Counsel. In part three of Doug’s three-part OBBBA discussion with Pat, they discuss the newly enacted OB3 reconciliation law, focusing on its permanent corporate and individual tax provisions, the recalibration of bonus depreciation, Section 174 expensing and Section 163(j); the Senate’s redesign of GILTI, FDII and BEAT; Inflation Reduction Act rollbacks; Treasury’s last-minute removal of Section 899; and the G7’s surprise accord intended to exempt US-parented groups from Pillar Two’s IIR and UTPR while elevating QDMTTs and compliance simplification. They map the procedural and legislative steps still needed, potential timing gaps, and why multinational groups must keep Pillar Two compliance front-of-mind.
