Portal Combat: Pillar Two Forms, Deadlines, and the Fight for Certainty

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Dr. Alexis Crow, partner and Chief Economist for PwC US. Prior to joining PwC, Alexis taught at the London School of Economics. Doug and Alexis discuss the macroeconomic and geopolitical implications of the Iran conflict, including energy-market scarring, oil-price scenarios, fiscal supports, inflation pressures, and central-bank constraints. They also examine the durability of US growth, AI-driven investment, consumer demand, and private credit risk; then move through global trade developments and regional dynamics across Asia-Pacific, Latin America, Europe, and North America. The conversation closes with the “re-industrial era,” energy addition, automation, workforce skills, and financial-stability risks that may be underappreciated. 

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Will Morris, PwC’s Global Tax Policy Leader, at PwC’s Asia-Pacific Global Tax Symposium in Hong Kong. Will previously chaired the Business and Industry Advisory Committee (BIAC) Tax Committee for 10 years. Doug and Will discuss the acute uncertainty surrounding Pillar Two filing readiness as initial 2024 calendar-year deadlines approach, including the OECD’s May 18, 2026, common understanding document, GIR central filing, local filing portals, XML schema differences, penalty relief, safe harbor elections, QDMTT and top-up tax returns, taxpayer outreach to BIAC, the OECD, and national governments, the OECD implementation toolkit, 52/53-week fiscal-year UTPR guidance, and unresolved dispute resolution questions. 

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Adriana Rodriguez, a PwC international tax partner based in Mexico City, for a discussion recorded at PwC’s International Tax Conference. Doug and Adriana discuss the core features of Mexico’s corporate tax system, including corporate income tax, withholding taxes, VAT, inflation adjustments, CFC rules, capital gains planning, and the impact of the multilateral instrument on treaty access. They also explore whether Mexico is likely to adopt Pillar Two, how Mexican multinationals are preparing for compliance, the role of incentives in inbound investment, the continued relevance of the maquila regime, rising audit and transfer pricing pressure, expanding tax authority digitization, and practical lessons for multinationals investing in Mexico.  

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Chris Desmond, leader of PwC’s US Global Trade Services practice and, as Doug notes, a ‘reformed transfer pricing partner.’ Doug and Chris discuss the current fragmented trade environment, why tariffs may remain a lasting feature rather than a short cycle, rising customs enforcement, the Supreme Court’s IEEPA decision and the operational complexity of securing refunds, and how companies should assess gross-versus-net refund exposure across suppliers and customers. They also cover why the tariff environment is forcing customs, tax, and transfer pricing teams to work more closely together, how first sale operates and why it remains under scrutiny, and practical steps tax leaders should take on coordination, data, and documentation. 

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Laura Valestin, an International Tax Services Partner in PwC’s Washington National Tax Services practice, where she focuses on financial transactions. In this episode, recorded at PwC’s International Tax Conference in Carlsbad, Laura unpacks the latest Section 987 developments following Notice 2026-17. Doug and Laura discuss what Section 987 is, why it matters for foreign currency gain or loss in branch and disregarded entity structures, the long regulatory history from the 1991 proposed regulations through the 2024 final rules, the new simplified equity-and-basis-pool method, remittance and loss-suspension mechanics, hedging rules, the proposed CFC election, reliance and applicability dates, and practical taxpayer action items, including comment opportunities and modeling decisions for 2025 and beyond. 

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Anja Manuel, co-founder and principal at Rice, Hadley, Gates, and Manuel LLC, a strategic consulting firm, and a former diplomat, author, and foreign policy advisor. Doug and Anja discuss the geopolitical forces reshaping cross-border business, including the Iran conflict and its implications for oil, shipping, Gulf investment, and AI infrastructure; China’s internal trajectory, tariffs, critical minerals, Taiwan, and supply-chain strategy; the growth outlook for Southeast Asia and India; Europe’s competitiveness challenges and the war in Ukraine; Venezuela’s political and investment risks; the effect of possible US midterm shifts on foreign policy; and whether international institutions, alliances, and the broader global economy still offer reasons for optimism despite a highly unstable backdrop. 

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Steve Kohart, a New York City-based international tax partner at PwC and former advisor to the OECD’s Center for Tax Policy and Administration. Doug and Steve discuss the January side-by-side agreement’s implications for US-parented multinationals, why Pillar Two remains relevant through QDMTTs, and how the CBCR transitional safe harbor bridges to the permanent simplified ETR safe harbor. They unpack what ‘simplified’ really means: financial accounting standards, denominator and numerator adjustments, deferred tax ‘bad DTLs,’ and the practical reality of a third set of books. The conversation also covers JV complications, Chapter 6 M&A/reorg rules, transition provisions (9.1.1–9.1.3) and excess negative taxes, new flexibility for return-to-provision adjustments, integrity rules, and what guidance and compliance planning teams should prioritize next. 

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Wade Sutton, a PwC principal who leads the International Tax Team in PwC’s Washington National Tax Services Practice and previously served as Deputy International Tax Counsel at the US Department of the Treasury. Doug and Wade discuss late-2025 Treasury and IRS guidance implementing cross-border provisions in the One Big Beautiful Bill Act (OBBBA), focusing on transition and compliance mechanics that surface on 2025 returns. They walk through Notice 2025-72 (CFC year-end conformity and short-period foreign tax allocation), Notice 2025-75 (final-year coordination of the 'hot potato' rule with Section 951A(2)(B) as the regime shifts to pro rata attribution), Notice 2025-77 (a 10% foreign tax credit haircut for taxes tied to certain previously taxed distributions), and Notice 2025-78 (limits on deduction-eligible export income for certain property and IP sales). They close with downstream interactions (especially CAMT and loss/FTC limitations) and how Pillar Two 'side-by-side' dynamics may influence structuring.

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Nils Cousin, an international tax partner in PwC’s Washington National Tax Services Practice, for his fourth appearance on the show. Doug and Nils discuss Nils’s April 2024 Jeopardy experience before pivoting to the 1916-era Section 892 exemption: how foreign governments, sovereign wealth funds, and public pension funds use it, and how ‘commercial activity’ and ‘controlled commercial entity’ rules can taint the benefit. They unpack the December 2025 regulation package, highlighting what was finalized (including an inadvertent-activity cure period, the qualified partnership exception, and FIRPTA taint relief) and what remains proposed, especially a framework that presumptively treats many debt acquisitions and workouts as commercial activity. The episode closes with the regulation process, effective-date mechanics, and a January 18 Treasury Secretary tweet, leaving us wondering whether market feedback might drive revisions. 

Doug McHoney (PwC’s International Tax Services Global Leader) is joined by Craig Stronberg, Senior Director on PwC’s Intelligence Team. Craig leads analysts focused on macroeconomic and geopolitical intelligence; he previously served in the Office of the Director of National Intelligence. Doug and Craig discuss why business and tax leaders should focus on the geopolitical landscape to understand its impact on cross-border business, including tax. Stability is the new bar for many businesses in 2026, requiring greater agility to deal with change. Craig discusses how many businesses are in a 'wait‑and‑see' mode versus decisive movers across industries. He also describes areas of focus, such as the US policy stance for the Americas, Greenland, and tariffs; the Global South’s rising coordination; and governance strains across the G20. While AI data falsification is a significant concern, Craig suggests practical actions for boards such as enabling direct access to the business’ risk team.
