Show notes

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Wade Sutton, International Tax Leader of PwC’s Washington National Tax Services practice and guest host of Cross-border Tax Talks. After Wade reflects on his previous experience at the US Treasury Department, he and Doug discuss four proposed regulation packages under the One Big Beautiful Bill Act (OB3): expense allocation for net CFC tested income (NCTI) and foreign-derived deduction-eligible income (FDDEI), FDDEI eligibility changes, CFC pro rata share rules, and repeal of the one-month deferral election. They examine foreign tax credit limitations, overall domestic loss exposure, M&A drafting and tax-year elections, and transition relief. The conversation also covers reconciliation prospects, regulatory comment periods, Loper Bright’s influence on Treasury’s approach, and anticipated guidance on foreign sales branches and foreign-controlled CFCs.

When regs lose their deference: Three cases rewrite the tax playbook Sep 24, 2026

Show notes

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Laura Williams, an international tax partner in PwC’s Washington National Tax Services office and former branch chief in the IRS Office of Chief Counsel. Doug and Laura discuss the role of Treasury regulations, Section 7805(a), and the post-Loper Bright limits on agency deference and delegated authority. They explain why TCJA’s mismatched effective dates created a ‘donut hole’ and examine three recent regulation-validity decisions: Varian Medical Systems, Keysight Technologies, and Siemens Medical Solutions. These cases concern the Section 78 gross-up, GILTI deductions, extraordinary dispositions, and the Section 245A dividends-received deduction. The conversation also addresses judicial precedent, protective refund claims, return and financial-statement positions, possible government appeals, and the IRS’s potential use of economic substance and other alternative arguments when challenged regulations do not survive.

They explain how the election can turn off future Section 987 gain-or-loss computations, while preserving translation and basis-tracking requirements, and examine consistency across commonly controlled CFCs, partnership applications, inbound transactions, and the loss of future Section 987 losses. They also cover the 120-month amortization of pre-election amounts, the $50 million asset threshold, election timing and filing mechanics, reliance on the proposed rules, the November 12 comment deadline, and why detailed modeling is essential before making an effectively irrevocable choice.
