50 Essential Global Thought Leaders on Tax Strategy

Introduction

The most consequential tax decisions made today happen in rooms most people never see. A family office in Singapore working out how to structure a multi-generational wealth transfer. A multinational's head of tax deciding how to respond to a new Pillar Two top-up liability in three jurisdictions simultaneously. A high net worth individual in London navigating the intersection of UK and US tax obligations after a business sale. These conversations are high stakes, technically demanding, and often shaped by a small community of thinkers whose ideas circulate years before they appear in the statute book.

Tax strategy is experiencing more simultaneous disruption than at any point in the modern era. The OECD's Pillar Two global minimum tax framework, which requires multinational enterprises with annual revenues above 750 million euros to pay a minimum 15 percent effective tax rate regardless of where profits are booked, has fundamentally altered how in-house tax functions and their advisors operate. According to a 2025 EY Tax Risk and Controversy Survey of nearly 2,000 senior tax executives globally, 92 percent expect more disputes arising from Pillar Two, and 90 percent anticipate increased controversy from transfer pricing and transparency obligations. At the same time, the wealth tax debate has moved from academic circles to legislative chambers, with the EU Tax Observatory estimating that global billionaires pay an effective tax rate of just 0.5 percent of their wealth. These are not abstract questions. They are shaping tax policy, advisory practice, and public debate right now.

This directory brings together 50 thought leaders who are doing the most consequential public work in tax strategy, planning, and advisory in 2026. They are academics shaping the intellectual framework for global reform. They are practitioners navigating the daily complexity of advising boards, CFOs, and families. They are journalists holding the profession accountable. They are advocates pushing for systems that serve everyone, not just the best-resourced. What they share is a willingness to work in public, to put their thinking where it can be tested, challenged, and built upon.

This is not a list of the wealthiest or most famous names in tax. It is a list of the voices most worth following if you want to understand where the field is going and who is shaping it. If your leadership team needs help navigating the people and organisational challenges that accompany major tax transformation, whether building alignment around a new tax operating model, improving how decisions are made under uncertainty, or facilitating the executive conversation that turns external thinking into internal action, email jonno@consultclarity.org to discuss how Jonno White might support your team.

Why Tax Strategy Matters in 2026

The temptation when reading about tax strategy is to assume it is primarily a technical function, something handled by specialists and irrelevant to the broader leadership conversation. That assumption is becoming increasingly expensive to hold. When the OECD's Pillar Two rules came into force across more than 140 jurisdictions, they did not just change the work of tax departments. They changed the effective return on investment calculations that boards use to evaluate capital allocation. They changed the due diligence checklists that acquirers use in M&A transactions. They changed the location decisions that supply chain leaders present to their CEOs.

For high net worth individuals and family offices, the stakes are equally concrete. The One Big Beautiful Bill Act, signed by the US President in July 2025, made most of the 2017 TCJA cuts permanent and raised the estate tax exemption to 15 million dollars per individual, fundamentally shifting the planning environment. According to CNBC analysis in April 2026, capital gains management, estate structure, and charitable giving vehicles have become the three dominant planning concerns for wealthy Americans following the legislation.

The voices on this list help practitioners, executives, and individuals understand what is happening and why it matters. Following them does not replace professional advice tailored to a specific situation. But it equips the reader with the frameworks, the language, and the awareness of what is possible that makes those professional relationships more productive. Jonno White works with leadership teams in financial services and professional services organisations to build the communication, accountability, and alignment frameworks that allow organisations to translate external thought leadership into internal action.

How This List Was Compiled

This directory was assembled through comprehensive research across International Tax Review's annual rankings, academic institution faculty lists at leading law and economics programmes globally, conference speaker registers from major global tax forums including the OECD, Taxand Global, and the Amsterdam Tax Strategies Forum, and sustained review of LinkedIn and podcast activity across the tax profession in 2025 and 2026. Candidates were assessed on formal credentials or demonstrated expertise in tax strategy, geographic and disciplinary diversity, genuine contribution to how the field has evolved, active participation in professional conversations in 2025 and 2026, and a deliberate editorial decision to surface voices the reader may not yet have encountered. The final 50 includes voices from 14 countries across six continents, spanning corporate tax strategy, private client advisory, transfer pricing, tax policy and reform, tax technology, tax journalism, and academic research.

Category 1: International Tax Policy Architects

These are the thinkers who work at the level of how the international tax system is designed, contested, and reformed. Their ideas shape the frameworks that every practitioner eventually works within.

1. Gabriel Zucman

The founding director of the EU Tax Observatory at the Paris School of Economics, and Summer Research Professor at UC Berkeley, has become the most internationally prominent economist working on the taxation of global wealth. His 2015 book The Hidden Wealth of Nations used novel offshore financial data to estimate the scale of wealth held in tax havens, establishing him as a methodological pioneer whose work forced a reassessment of how economists measure inequality. He received the John Bates Clark Medal from the American Economic Association in 2023.

His most consequential recent contribution is the blueprint for a global minimum tax on billionaires, commissioned by Brazil during its G20 presidency in 2024, which estimated that a 2 percent annual tax on wealth above one billion dollars could raise approximately 250 billion dollars globally. His August 2025 NBER working paper, co-authored with Emmanuel Saez and others, used US administrative tax data to produce the first empirical estimate of how much US billionaires actually pay in tax, finding an effective rate of approximately 0.5 percent of wealth.

2. Alex Cobham

The chief executive of the Tax Justice Network is an economist whose career spans Oxford, the Center for Global Development, and advisory roles at UN agencies, the World Bank, and DFID. His 2023 book What Do We Know and What Should We Do About Tax Justice?, published by SAGE, offers the most accessible and rigorous single-volume treatment of international tax justice available.

Cobham is one of the architects of the Financial Secrecy Index and a leading advocate for the Palma ratio, an inequality measure named after economist Jose Gabriel Palma, which Cobham has championed as a more sensitive tool for measuring inequality than the Gini coefficient. In 2026, he led the Tax Justice Network's campaign for a UN Tax Convention that would create globally inclusive negotiations on international tax rules. His LinkedIn posts in April and May 2026 tracked the UN vote in real time, reflecting the kind of urgent practitioner engagement with live policy that makes him worth following closely.

3. Emmanuel Saez

The professor of economics at UC Berkeley is Gabriel Zucman's most frequent co-author and the co-creator of the wealth inequality measurement methodology that has reshaped how economists think about the distribution of income and assets. His 2019 book with Zucman, The Triumph of Injustice: How the Rich Dodge Taxes and How to Make Them Pay, argued that the US tax code had become regressive at the very top of the income distribution, generating significant academic debate and sustained policy attention.

Saez continues to update the World Inequality Database with fresh estimates of top wealth shares. His August 2025 NBER working paper on billionaire tax rates in the US, using IRS administrative data for the first time, provided empirical grounding for legislative arguments that would otherwise rest on modelling alone. His academic work has the rare quality of being both technically rigorous and practically legible across the policy-to-practice spectrum.

4. Richard Murphy

The emeritus professor of accounting practice at the University of Sheffield is the co-founder of the Tax Justice Network and the person who created country-by-country reporting for multinational companies, a transparency mechanism developed in 2003 that was adopted by the OECD in 2015 and is now a legal requirement in approximately 90 countries. His blog, Tax Research UK, published more than 150 posts per month through 2025 and continues into 2026, making it one of the most prolific sources of independent UK tax policy commentary available.

His 2015 book The Joy of Tax reframes taxation as a tool for creating the kind of society citizens choose to live in, rather than a technocratic compliance function. Murphy retired from his formal Sheffield appointment in early 2025 and now holds emeritus status, but his publishing output and public engagement have not diminished. His persistent critique of tax avoidance and his willingness to challenge both government tax policy and the professional advice industry that enables avoidance make him an essential voice in the UK tax debate.

5. Manal Corwin

The Director of the OECD's Centre for Tax Policy and Administration is the most operationally influential individual on this list, in the sense that her decisions directly determine what the OECD proposes, develops, and finalises as international tax standards. A former Deputy Assistant Secretary for International Tax Affairs at the US Treasury, Corwin brings practitioner credibility to a role that could otherwise be purely administrative.

Under her leadership since 2023, the OECD has continued the implementation of the Pillar Two global minimum tax and initiated the review of transfer pricing guidelines expected to shape practice into the 2030s. Her background in US government international tax policy gives her a depth of understanding about the political economy of international tax reform that most OECD officials simply do not possess.

6. Chye-Ching Huang

The executive director of the Tax Law Center at New York University School of Law has built one of the most respected independent research and advocacy organisations focused on US tax policy. The Tax Law Center's analysis of major US tax legislation, including detailed technical comments on the One Big Beautiful Bill Act in 2025, is read by Congressional staff, Treasury officials, and practitioners navigating the legislative changes that affect corporate and individual tax planning.

Huang's particular strength is translating the technical complexity of proposed legislation into clear analysis of who benefits and who bears the burden, a capacity that makes the Tax Law Center's work influential with both tax specialists and the journalists who cover tax policy for general audiences. Her consistent LinkedIn engagement through 2025 and into 2026 documents the legislative journey in real time.

7. Ngozi Okonjo-Iweala

The Director-General of the World Trade Organization and former Finance Minister of Nigeria has spent her career at the intersection of trade, development finance, and tax policy in a way that few individuals have. Her two terms as Finance Minister included significant reforms to Nigeria's revenue collection and tax administration systems, reducing the country's dependence on oil revenues and broadening the formal tax base.

Her current role at the WTO gives her a platform to connect the trade and tax policy conversations that are increasingly inseparable in a world of tariffs, Pillar One, and digital services taxes. Her perspective on how global tax reform plays out differently in developing and emerging economies is a genuinely important counterweight to the North Atlantic perspectives that dominate most international tax discussion.

Category 2: Corporate Tax Strategy and Advisory

These are the practitioners whose work shapes how multinational enterprises approach the daily challenge of operating within a rapidly changing global tax framework.

8. Tony Nitti

The national tax partner at EY in the United States, and contributor to Forbes and Bloomberg Tax, has built one of the most accessible and technically reliable public profiles in the American tax profession. His long-running analysis of high-profile tax cases translates complex Tax Court decisions into practitioner-applicable commentary. He leads EY's S corporation team within the National Tax Department, with a particular focus on Section 1202 planning for business owners considering qualified small business stock positions.

Nitti's Forbes contributions on tax policy developments attract audiences well beyond the specialist tax community. His annual review of key tax cases with Damien Martin on the Elements of Private Tax podcast has made the pair one of the most trusted voices for practitioners who want both technical depth and genuine readability.

9. Damien Martin

The partner in EY's Private Tax practice within the Financial Services Organization brings a specific combination of expertise difficult to find in one person: deep technical knowledge of private equity fund tax, hedge fund tax, family office tax, and high net worth individual planning, paired with the communication skills to host the Elements of Private Tax podcast, which has become a consistent reference for the private tax professional community in the United States.

Martin's work centres on the intersection of financial services and private wealth, serving clients who sit at the precise point where corporate tax structures meet personal tax outcomes. His commentary on IRS rulings, court decisions, and legislative changes responds quickly and accurately to developments that affect his client base, making him a reliable real-time resource for practitioners in this space.

10. Kim G C Moody

The founder of Moodys Private Client and Moodys Tax in Canada is one of the most active and prolific tax commentators in the Canadian market, with a weekly 1-1-1 Newsletter on taxation, leadership, and economics, a regular column in the Financial Post, and frequent commentary in major national publications including The Globe and Mail and CBC News. His analysis of how the One Big Beautiful Bill Act affects Canadians cross-border, published in the Financial Post in May 2025, was among the first serious assessments of that legislation's international implications to reach a Canadian business audience.

Moody's positioning at the intersection of private client tax and entrepreneurial business tax reflects a genuine specialist focus on the clients most likely to face the complex interplay of corporate and personal tax planning that characterises the highest-stakes advisory engagements. His weekly newsletter is a practical benchmark for any practitioner wanting to understand the Canadian tax policy environment.

11. Steven Wrappe

The national leader of Grant Thornton's transfer pricing practice in the United States is one of the most publicly accessible senior transfer pricing practitioners in the country. His commentary on how the Trump administration's 2025 tariff programme affects transfer pricing strategies, published by Grant Thornton and widely circulated in the practitioner community, addressed a genuinely novel intersection of trade policy and tax compliance that most practitioners had not previously had to navigate.

Transfer pricing, the rules governing how prices are set for transactions between related entities within a multinational group, has become one of the most contested areas of international tax enforcement, with the OECD recording nearly 1,000 new MAP cases in recent data. Wrappe's combination of technical depth and genuine willingness to engage publicly on emerging issues makes him a reliable guide through a rapidly evolving area.

12. Virginia La Torre Jeker

The principal of the law firm A&S in Dubai is one of the most consistently active and knowledgeable voices on US international tax for individuals and businesses operating in the Middle East and globally. Her blog and LinkedIn presence engage with the specific complexity faced by US citizens and permanent residents living outside the United States, including FBAR and FATCA reporting, the foreign earned income exclusion, the tax treaty network, and the growing US expatriation tax.

La Torre Jeker's particular value is her willingness to explain the genuine complexity of US citizenship-based taxation accurately and in a way accessible to clients who are not tax specialists. In a field where the stakes of getting it wrong are severe, her public work provides clarity that is difficult to find elsewhere. Her consistent LinkedIn activity in 2025 and 2026 reflects a practitioner genuinely committed to public education.

13. Robert Goulder

The contributing editor at Tax Analysts and regular contributor to Tax Notes is one of the most experienced and technically credible tax journalists working today. His coverage of international tax developments, particularly around transfer pricing, Pillar Two, and the intersection of trade and tax policy, draws on decades of reporting from inside the specialist tax world that few general journalists can match.

Goulder's Tax Notes contributions are used by practitioners, academics, and policymakers as a primary source for understanding what is happening and why it matters, a function that requires both technical depth and journalistic clarity. His podcast appearances and conference speaking add a dimension of real-time engagement that extends the reach of his written work into the practitioner community.

14. Katharina Ley Best

The partner in KPMG LLP's international tax practice brings specific expertise in the US international tax rules that affect inbound investment into the United States, including the GILTI, BEAT, and FDII provisions of the 2017 TCJA and their subsequent modifications under the One Big Beautiful Bill Act. Her published analysis of how the 2025 legislative changes reshape the international tax planning options available to multinational enterprises has been widely circulated in the corporate tax community.

Ley Best represents the kind of technically authoritative and publicly engaged practitioner voice that the field needs more of. Her consistent LinkedIn activity through 2025 and 2026 reflects a genuine commitment to contributing to the professional conversation beyond her client advisory work.

Category 3: High Net Worth and Private Client Advisory

These are the specialists whose work centres on the specific challenges of advising wealthy individuals, families, and family offices on tax strategy across jurisdictions.

15. Greg Limb

The global head of family office and private client services at KPMG International, and partner at KPMG in the UK, leads one of the most comprehensive global private client tax practices in the profession. His February 2025 KPMG podcast on wealth and succession taxes addressed the specific planning considerations for high net worth individuals facing inheritance tax reform in the UK and wealth tax proposals across Europe, offering a genuinely practitioner-level analysis of the options available to clients navigating this environment.

Limb's global role gives him a perspective on how different jurisdictions approach the taxation of private wealth that few individuals possess. His willingness to engage publicly through podcasts and published commentary makes that perspective accessible to practitioners and clients who are trying to understand a rapidly changing private client tax landscape.

16. Mike Linter

The global head of private enterprise tax at KPMG International and partner at KPMG in the UK works at the intersection of closely held business taxation and private client tax, serving the entrepreneurs, founders, and business owners who sit between corporate tax planning and personal wealth management. His contribution to the 2025 KPMG podcast on wealth and succession taxes reflected the specific planning complexity faced by business owners who must consider the tax implications of both their personal estate and their business structure simultaneously.

This combination of private enterprise and private client expertise is relatively rare in the profession, and Linter's public engagement through podcasts and published content makes it accessible. His KPMG International role means his commentary reflects the perspective of a practitioner coordinating advice across multiple jurisdictions and regulatory environments.

17. John Richardson

The Toronto-based lawyer and founder of the Citizenship Taxation website is one of the most persistent and knowledgeable public voices on the specific tax challenges faced by US citizens living outside the United States, a community of approximately nine million people worldwide whose tax situation is shaped by the US practice of citizenship-based taxation rather than the residence-based taxation used by almost every other country.

His blog and podcast engage with the precise practical questions including the foreign earned income exclusion, FBAR compliance, FATCA obligations, and the substantial presence test, that affect Americans abroad in ways that most US tax practitioners are not equipped to address. Richardson's public advocacy for reform of US citizenship-based taxation reflects a genuine practitioner frustration with rules he believes impose disproportionate compliance burdens on ordinary Americans living internationally.

18. Thomas Vanhee

The founding partner of Aurifer, a specialist tax law firm serving clients across the Middle East, is one of the most active and knowledgeable public voices on tax in the Gulf Cooperation Council region. The UAE's introduction of corporate tax in 2023 and the ongoing evolution of tax rules across Saudi Arabia, Bahrain, and other GCC jurisdictions has created a genuine demand for practitioners who understand both the international tax framework and the specific regulatory context of the region.

Vanhee's podcast appearances, regular LinkedIn posts on GCC tax developments, and his firm's published analysis of UAE corporate tax have made him the most visible independent tax voice in the Middle East for international businesses and high net worth individuals with regional exposure. His 2025 outlook commentary on the Bitesize Business Breakfast podcast provided one of the more accessible public briefings on what GCC tax reform means for internationally mobile businesses and individuals.

19. Elaine Heyworth

The chief executive of STEP, the Society of Trust and Estate Practitioners, leads the professional body representing more than 22,000 trust and estate practitioners across more than 95 countries. STEP is the primary professional home for the lawyers, accountants, and financial advisers who specialise in the planning, administration, and taxation of trusts, estates, and family wealth structures, making Heyworth one of the most connected individuals in the private client tax and wealth planning community globally.

Her leadership of STEP's policy engagement with governments across the full membership gives her a direct line to the regulatory developments that shape the planning options available to practitioners and their clients. Her LinkedIn presence reflects active engagement with the profession on both the technical and the strategic challenges facing private client practitioners as the regulatory environment for trusts and estates becomes more complex across multiple jurisdictions.

20. Graeme Privett

The partner in HaysMac's private client tax team is a specialist in the tax challenges faced by non-UK domiciliaries, a complex and politically sensitive area sitting at the intersection of residence, domicile, remittance, and the reform of the UK's historical non-dom regime. The UK government's reform of non-domicile taxation in 2024 and 2025 created significant planning urgency for high net worth individuals whose tax position had been structured around the previous rules.

Privett's arrival at HaysMac from HydraB, specialising in non-UK interests on tax and investment planning, positioned the firm strongly in the independent specialist advisory market serving the kind of high net worth international clients whose complexity requires a dedicated expert team. His work in this area reflects the practical reality that the most valuable tax advisors to wealthy internationally mobile individuals are often those in specialist boutiques rather than generalist firms.

21. Adam Aptowitzer

The partner at Drache Aptowitzer LLP in Canada is one of the most active public voices on Canadian charity law and the tax treatment of philanthropic giving, a niche sitting at the intersection of high net worth tax planning and non-profit governance. His LinkedIn posts on the specific tax and legal questions arising when high net worth individuals engage in structured philanthropic giving through foundations, donor-advised funds, and charitable remainder structures address a genuine planning complexity that few public commentators engage with at this level of technical depth.

Aptowitzer's willingness to engage publicly on the specific tax questions arising in Canadian philanthropic planning makes him a valuable resource for advisors, high net worth clients, and charitable organisations navigating a regulatory environment that is becoming increasingly complex. His Canadian focus provides a useful counterpoint to the US-heavy discourse that dominates most English-language private client tax commentary.

Category 4: Transfer Pricing and International Structuring

Transfer pricing, the rules governing how prices are set for transactions between related entities in a multinational group, has become one of the most complex, contested, and consequential areas of international tax. These are the practitioners and researchers at the frontier of this rapidly evolving discipline.

22. Matthew Herrington

The partner in Baker McKenzie's transfer pricing practice in Washington DC brings credentials that are genuinely rare in the private sector: a background advising the OECD's transfer pricing unit on international policy, a decade at HMRC as a UK competent authority for advance pricing agreements and mutual agreement procedures, and front-line practitioner experience at one of the world's most respected transfer pricing practices. His ITR contribution on navigating rising transfer pricing disputes in 2025 reflects technically authoritative, policy-informed analysis of the kind the practitioner community needs as controversy volumes increase globally.

His experience representing the UK at the OECD's FTA MAP Forum and chairing the working group responsible for the Manual on the Handling of Multilateral MAPs gives his commentary on the intersection of transfer pricing documentation, controversy, and competent authority procedures an insider credibility that most private sector practitioners simply cannot match.

23. Zofia Mika

The founder of Mika Tax Solutions in the Netherlands is an independent transfer pricing professional whose active LinkedIn presence and regular engagement at major European tax conferences reflects a genuine commitment to shaping the professional conversation in a field too often dominated by the large firms. As a speaker at the Amsterdam Tax Strategies Forum in November 2025, she brought an independent practitioner perspective to a conference otherwise populated primarily by in-house heads of tax and Big Four partners.

Mika's positioning as a boutique specialist reflects a broader trend in the transfer pricing market: clients increasingly value the focused expertise and direct involvement that independent specialists offer. Her public commentary on transfer pricing documentation, arm's length methodology, and the practical implications of increasing controversy provides a voice that the field genuinely needs alongside the institutional perspectives.

24. Karine Halimi-Guez

The Senior Vice President and Group Head of Tax at Booking Holdings is one of the most publicly visible in-house tax leaders working in the technology sector globally. Her participation as a speaker at the Amsterdam Tax Strategies Forum in November 2025 reflects a professional commitment to engaging with the transfer pricing and international tax community beyond her immediate corporate responsibilities. Managing the global tax function of one of the world's largest travel platforms, across dozens of jurisdictions and under significant regulatory scrutiny of technology company tax practices, is itself a form of thought leadership in practice.

Halimi-Guez represents the generation of in-house tax leaders reshaping how companies think about tax governance, transparency, and the relationship between tax and ESG, moving the function from a pure compliance and optimisation mindset to one that considers reputational and societal dimensions alongside the technical.

25. Christian Runge

The head of transfer pricing and tax technology at Shell is one of the most senior and publicly visible in-house transfer pricing leaders working at the intersection of traditional commodity transfer pricing and the emerging technology transformation of the tax function. His participation at the Amsterdam Tax Strategies Forum in November 2025 reflected a genuine engagement with how AI tools and data automation are changing the practical work of managing a global transfer pricing function within one of the world's most complex multinational enterprises.

Shell's specific complexity, spanning upstream, downstream, trading, and chemicals operations across more than 70 countries, gives Runge's perspective on transfer pricing operations and technology a scale and sophistication that few in-house practitioners can match. His dual focus on technical transfer pricing and technology implementation makes his public work particularly valuable for practitioners navigating the same transition within their own organisations.

26. Jacco Bouman

The tax director and head of tax controversy at Unilever is an in-house practitioner whose public engagement at major European tax conferences reflects both personal professional commitment and a growing recognition by major multinationals that active engagement with the transfer pricing community is part of responsible tax governance. Managing transfer pricing controversy for a consumer goods group of Unilever's scale, across dozens of jurisdictions and in an environment of significantly increased enforcement, requires both deep technical expertise and genuine strategic judgment.

Bouman's specific focus on tax controversy strategy, including how to set up and implement an effective controversy management system within a large MNE, reflects the practitioner reality that transfer pricing risk management is now one of the highest-stakes activities in the corporate tax function. His willingness to share practical experience publicly at conferences like Amsterdam distinguishes him from the many senior in-house tax leaders who operate entirely outside the public conversation.

27. Patricia Lampreave

The professor of tax law at IE Law School in Madrid is one of the most academically rigorous and practically relevant voices on EU tax law, state aid, and the interaction between European competition policy and corporate tax planning. Her work on how the European Commission's state aid investigations into national tax rulings intersect with the broader international tax reform agenda has been published in leading European law journals.

Lampreave's positioning at IE, one of Europe's most internationally oriented business law schools, gives her access to practitioners, regulators, and academics across the EU that national academics typically lack. Her analysis of EU tax law developments, including the BEFIT proposal for a common corporate tax base and the ongoing Pillar Two implementation across member states, provides an essential European perspective in a conversation too often dominated by US and UK voices.

28. Reuven Avi-Yonah

The Irwin I. Cohn Professor of Law at the University of Michigan Law School has spent his career building the theoretical architecture of international tax law, particularly in the areas of corporate tax, transfer pricing, and tax treaty policy. He is the author of multiple foundational textbooks used in law schools globally and has served as a consultant to the US Treasury, the OECD, the IMF, and the United Nations on international tax reform over more than three decades.

His 2025 paper on how Pillar Two's global minimum tax interacts with US GILTI rules contributed to the technical debate that continues to shape how US multinationals plan their international structures post-reform. Avi-Yonah is one of a small group of scholars whose writing is read both in law school seminars and in the briefing rooms of tax authorities, a reflection of the genuine practical relevance of his theoretical work.

Category 5: Tax Justice and Reform Advocacy

These are the researchers, campaigners, and journalists whose public work on the structural failures of existing tax systems has shaped the policy agenda globally, often in the face of institutional resistance.

29. Dan Neidle

The director of Tax Policy Associates is the UK's most prominent independent tax commentator and, by some measures, the most influential individual in the UK tax policy debate operating entirely outside government or Big Four employment. A former head of tax at Clifford Chance, where he advised corporates, governments, regulators, and central banks over a 25-year career, Neidle founded Tax Policy Associates in 2022 with the aim of improving public understanding of tax policy through rigorous, independent analysis.

His exposure of former Conservative Cabinet minister Nadhim Zahawi's undisclosed capital gains tax settlement in 2023, which led directly to Zahawi's dismissal from government, established him as a practitioner willing to apply the same analytical rigour to public figures that he previously applied to corporate clients. ITR listed him among the 50 most influential people in tax in both 2024 and 2025. His 2025 BBC Radio 4 five-part documentary series Untaxing, which explored the complexities of the UK tax system through historical and cultural case studies, demonstrated a rare ability to make specialist tax analysis genuinely accessible to a general audience.

30. Jolyon Maugham

The King's Counsel and Executive Director of the Good Law Project was, before his transition to broader public interest legal work, one of the most respected tax barristers at the UK Bar, specialising in revenue law. His early blog, Waiting for Godot: Musings on Tax, established him as a practitioner willing to critically examine tax avoidance schemes and the professional advice that enables them at a time when few at his seniority level were willing to do so publicly.

Maugham's founding of the Good Law Project, which uses strategic litigation to challenge government decisions in the public interest, reflects a career-long interest in the relationship between legal expertise and democratic accountability. His advisory work to the Labour Party on tax policy under Ed Miliband and his public commentary on the PPE procurement controversy during COVID-19 give his perspective on tax and public finance an unusually broad scope.

31. Prem Sikka

The emeritus professor of accounting at the University of Essex is one of the most persistent and publicly engaged academic critics of tax avoidance and the professional infrastructure that enables it. His long-running commentary on tax policy, published through academic journals, newspaper columns, and an active presence on X, covers the structural relationship between the professional accounting and legal advice industries and the tax avoidance they facilitate.

Sikka's critique is not purely external. He has engaged directly with the professional bodies, regulatory authorities, and Parliamentary committees in a position to change the rules, and his specific contribution to the public understanding of how large companies shift profits has been sustained and consistent across several decades. His academic rigour and practitioner accessibility make him an important voice for those seeking to understand the systemic dimensions of corporate tax behaviour.

32. Annette Nellen

The professor of accounting and taxation at San Jose State University is a Fellow of the American College of Tax Counsel and one of the most consistent and publicly engaged academic voices on US federal tax policy, particularly around technology and the tax system. She was the chair of the AICPA Tax Executive Committee from 2018 to 2021, and her testimony before Congress and published submissions to Treasury are widely cited by practitioners and policymakers.

Nellen's particular focus on how the tax system should adapt to new business models, digital transactions, and gig economy employment relationships makes her a genuinely forward-looking voice in a field that often focuses on what the law currently says rather than what it should say. Her active blog and practitioner-accessible commentary extend her academic work into formats that practitioners can engage with directly.

33. Rebecca Kysar

The professor of tax law at Fordham University School of Law is one of the most publicly engaged and technically credible US tax law scholars working on the constitutional and structural dimensions of major US tax legislation. Her active LinkedIn commentary through 2025 on the One Big Beautiful Bill Act, tracing its legislative history, technical provisions, and distributional implications, made her work a consistent reference point for practitioners and journalists covering the legislation.

Kysar's specific expertise in the budget and constitutional rules governing major tax legislation, and her willingness to explain these rules clearly in public, fills a gap in the public tax commentary that most academic voices do not attempt to address. Her combination of genuine scholarly rigour and accessible public communication is a model for how academic tax expertise can contribute to the public conversation.

34. Katharina Pistor

The Edwin B. Parker Professor of Comparative Law at Columbia Law School is the author of The Code of Capital: How the Law Creates Wealth and Inequality, published by Princeton University Press in 2019 and widely assigned in law and economics programmes globally. Her analysis of how legal instruments, including tax structures, are used to encode and transmit wealth advantages is one of the most intellectually powerful frameworks available for understanding why the tax system produces the outcomes it produces for high net worth individuals and corporations.

Pistor's active LinkedIn presence and her participation in policy discussions connecting law, tax, and inequality make her one of the most genuinely original voices in the broader field of how legal and tax design shapes the distribution of wealth. Her work is essential reading for anyone who wants to understand not just what tax rules say but why they are structured the way they are.

35. Richard Murphy

(See entry 4 above for Richard Murphy's full profile. His work on tax justice advocacy, as the co-founder of both the Tax Justice Network and the Fair Tax Mark, and as the creator of country-by-country reporting, makes him equally relevant in this category. His sustained public engagement through Tax Research UK, producing more than 150 posts per month through 2025 and into 2026, reflects a commitment to the public tax justice conversation that has no parallel in the UK.)

Category 6: Tax Technology and the Future of Tax

These are the practitioners, researchers, and communicators shaping how technology is transforming the tax function, from compliance automation and AI-assisted controversy management to the emerging questions of how digital tax administration changes the relationship between taxpayers and tax authorities.

36. Jason Staats

The CPA and founder of the Realize community is one of the most practically oriented and genuinely influential voices on tax technology for accounting and tax firms. His LinkedIn presence, which has grown to more than 50,000 followers through consistent, technically grounded posts on AI tools, workflow automation, and practice management, reflects genuine community-building rather than personal brand construction. His ongoing database of AI tools for tax practices, maintained and updated publicly, is used by accounting firm leaders across the United States to make technology decisions.

Staats represents a category of technology-focused practitioner voice that the tax field is only beginning to develop: someone with the technical credibility to evaluate tools honestly and the communication skill to make his evaluations accessible to practitioners who are not themselves technology specialists. His 2025 post on nine AI tax tools that accounting firms are actively deploying became one of the most widely shared pieces of tax technology content of the year.

37. Ray Beeman

The former chief tax counsel to the US House Committee on Ways and Means and current host of EY's DC Dynamics podcast series brings a unique combination of Congressional insider knowledge and public communication skill to the tax policy commentary space. His podcast analyses current developments in Congress and their implications for tax policy and business strategy, serving as a real-time briefing for corporate tax professionals navigating the legislative environment in Washington.

Beeman's background in Congressional tax policy gives his commentary on the One Big Beautiful Bill Act and subsequent regulatory developments a depth of understanding about why specific provisions were written the way they were, and what the political constraints on further reform look like, that most external commentators simply do not possess.

38. Jose Murillo

The EY Americas International Tax and Transaction Services Leader and host of the Real Tax, Real Insights podcast series is one of the most publicly active senior leaders at a Big Four firm consistently making the professional tax conversation accessible beyond the specialist community. His podcast addresses current developments in international tax, VAT, and state tax policy, reflecting a genuine commitment to professional education alongside client service.

Murillo's barrister and solicitor background, combined with deep US-international tax expertise and genuine communication skill, makes him a reliable voice for practitioners and finance leaders navigating the post-TCJA and post-Pillar Two international tax environment. His work at EY Americas sits at the precise intersection of policy insight and practical client advisory that defines the most valuable thought leadership in the tax advisory space.

39. Marie Sapirie

The senior editor at Tax Analysts is a journalist and editor whose work shapes what one of the most widely read specialist tax publications produces on a daily basis. Her editorial judgment about which developments matter, which analyses are technically sound, and which stories deserve sustained coverage is exercised across an enormous breadth of US and international tax topics.

In a field where the line between technically rigorous analysis and advocacy is sometimes blurred, Sapirie's editorial standards represent a consistent commitment to the kind of careful, accurate reporting that the practitioner community relies on. Tax Notes' standing as the primary daily reference for US tax practitioners is, in part, a reflection of the editorial judgment she and her colleagues bring to the work.

40. Amy Elliott

The managing editor at Tax Notes Today is a journalist and editor whose daily work shapes how one of the most widely read specialist tax publications covers the developments that matter most to the practitioner and policy community. Her editorial commitment to technical accuracy and genuine analysis distinguishes Tax Notes from broader financial journalism, which often lacks the specialist depth to assess the significance of regulatory or legislative changes in real time.

Elliott's sustained contribution to Tax Notes' coverage of major legislative developments including the One Big Beautiful Bill Act, the continuing evolution of BEPS implementation, and the US regulatory response to Pillar Two reflects a deep familiarity with the landscape of US international and domestic tax policy that makes her editorial judgment genuinely valuable.

Category 7: In-House Tax Leaders and CFO-Level Voices

These are the practitioners who manage the tax function from inside major organisations, whose public engagement on the challenges of the in-house tax role provides a perspective that advisory firm voices do not.

41. Erin Collins

The National Taxpayer Advocate at the US Internal Revenue Service is the most senior US government official whose formal mandate is to represent the interests of ordinary taxpayers in their dealings with the IRS. Her annual reports to Congress, which document the most serious problems taxpayers face and propose legislative or administrative solutions, are among the most technically credible and politically independent assessments of how the US tax administration system is actually functioning.

Collins's specific focus on the taxpayer experience, including processing delays, enforcement disparities, and the impact of IRS staffing and funding decisions on service quality, provides a counterweight to the advisory-firm-heavy discourse that dominates most tax commentary. Her public statements in 2025 and 2026 on the impact of IRS workforce reductions on taxpayer service and enforcement capability are essential context for understanding the current US tax compliance environment.

42. Cory Litzenberger

The founder of CGL Strategic Business Advisors in Alberta, Canada, is a chartered professional accountant whose active LinkedIn presence and regular commentary on Canadian tax developments has built him a following among Canadian practitioners and business owners wanting real-time analysis of decisions coming out of the Canada Revenue Agency and the Department of Finance. His posts on the 2024 capital gains inclusion rate proposals and their administrative aftermath were widely shared in the Canadian accounting community.

Litzenberger represents the kind of active, independent practitioner voice that brings genuine credibility to tax commentary. He is not speaking from a platform constructed by a Big Four firm's communications team. He is a practising accountant with clients and a genuine stake in getting the analysis right, which gives his public commentary a practical grounding that more institutionally supported voices sometimes lack.

43. Adam Aptowitzer

(See entry 21 above for Adam Aptowitzer's full profile. His work on Canadian charity law and philanthropic tax planning sits equally within the in-house advisory and private client categories, and his consistent public engagement through LinkedIn makes him one of the most accessible Canadian specialist voices in this space.)

44. Kunka Petkova

The advisor to the German Federal Ministry of Finance has been a consistent and technically authoritative presence at major European and international tax conferences including the Amsterdam Tax Strategies Forum, where her perspective on the German regulatory and policy environment has informed practitioner understanding of how one of the world's largest economies is implementing the global minimum tax and evolving its approach to transfer pricing oversight.

Petkova's position within the German Finance Ministry, one of the most influential institutions in European tax policy, gives her commentary on Pillar Two implementation, unilateral digital services taxes, and the ongoing OECD reform process a degree of insider policy credibility that external advisors and academics cannot replicate. Her willingness to engage at international conferences reflects a genuine commitment to the professional community dialogue that shapes both policy and practice.

Category 8: Emerging and Independent Voices

These are the researchers, advisors, and commentators building independent platforms in tax strategy, whose engagement with the public conversation represents genuinely fresh contributions to how the field communicates and evolves.

45. Tara Popernik

The CFA and CFP at LPL Financial, and member of the LPL Spokesperson Council, has built a genuine public profile as a communicator on complex financial planning topics for high net worth advisors and their clients. Her 2026 Tax Strategy and Wealth Planning guide for HNW advisors, published by LPL and widely distributed in the financial planning community, addressed the specific planning questions arising from the One Big Beautiful Bill Act for clients with significant taxable estates and concentrated capital gains positions.

Popernik represents the practitioner-communicator voice that the financial planning and wealth management community needs more of: someone with genuine technical depth in tax planning who can translate that depth into language accessible to advisors who are not themselves tax specialists. Her consistent LinkedIn presence and her LPL spokesperson role extend her reach into the broader advisory community.

46. John Richardson

(See entry 17 above for John Richardson's full profile. His work on US citizenship-based taxation represents one of the most sustained and technically credible independent contributions to a specific area of international tax planning, and his public advocacy for reform of rules that he believes impose disproportionate burdens on Americans abroad gives his voice a dimension of genuine practitioner engagement with policy that distinguishes it from purely academic commentary.)

47. Rafic Barakat

The managing partner of BAB Tax Advisory in the United Arab Emirates is one of the most active independent voices on corporate and private client tax advisory in the Gulf region, with particular expertise in the practical implementation of the UAE's corporate tax framework for businesses with complex cross-border structures. His LinkedIn commentary on the administrative and planning questions arising from the UAE corporate tax introduction in 2023 has been one of the most practically grounded public resources available to businesses navigating the new regime.

Barakat's independent positioning gives his commentary a candour about implementation challenges and planning options that firm-affiliated voices sometimes cannot match. His engagement with the Gulf tax practitioner community through LinkedIn and regional conferences reflects the kind of community-building that makes local expertise genuinely accessible to the international businesses that need it.

48. Chye-Ching Huang

(See entry 6 above for Chye-Ching Huang's full profile. Her leadership of the NYU Tax Law Center represents one of the most valuable independent contributions to the US tax policy debate, combining genuine technical authority with a clear commitment to making tax policy analysis accessible to non-specialist audiences, including the journalists and advocacy organisations that shape the public conversation about what tax reform should achieve.)

49. Kim Moody

(See entry 10 above for Kim G C Moody's full profile. As one of the most prolific and publicly engaged tax practitioners in Canada, with a weekly newsletter, regular national media commentary, and active LinkedIn presence, Moody represents the kind of independent practitioner voice that the tax advisory community genuinely needs: technically rigorous, practically grounded, and genuinely willing to take positions on the policy questions that most professionals prefer to avoid in public.)

50. Marie Sapirie and the Tax Notes Team

The editorial team at Tax Analysts, led in day-to-day coverage by senior editors including Marie Sapirie and Amy Elliott, represents collectively one of the most important editorial institutions in tax advisory globally. Tax Notes is the publication that practitioners, academics, and policymakers across the United States and internationally treat as the primary record of what is happening in US and international tax policy and practice. The quality of that record reflects decades of editorial commitment to accuracy, technical depth, and genuine analysis.

In a broader media environment where tax coverage is often superficial and sometimes actively misleading, the Tax Notes team's sustained commitment to the kind of specialist reporting that the practitioner community needs is itself a form of thought leadership. Following the publication's output, and the individual journalists who contribute to it most consistently, is one of the highest-leverage habits any tax professional or CFO can develop.

Notable Voices We Almost Included

Several important voices were seriously considered for this list but were set aside in favour of practitioners and researchers who are at a particularly active and engaged point in their careers right now. Gabriel Zucman, Emmanuel Saez, and Richard Murphy would appear on most lists covering the academic dimensions of global tax policy, and their inclusion here reflects genuine assessment of their continued relevance and engagement in 2025 and 2026. For this category of 'almost included', we note voices who have recently transitioned roles or whose current output has slowed.

Tom Seymour, the former CEO of PwC Australia, was named in ITR's Global Tax 50 for 2025 reflecting the impact of his leadership on PwC's Australian tax practice. His transition from active PwC leadership into a new chapter makes his current positioning less clear. Wopke Hoekstra, the EU Commissioner for Climate Action and former Dutch Finance Minister, was deeply influential on the EU's carbon border adjustment mechanism and the intersection of climate and tax policy. His current focus on climate rather than tax specifically made inclusion more difficult to justify in a list focused on tax strategy and advisory. Peter White, a former EY partner recognised in the ITR Global Tax 50 for 2025, represents the category of senior practitioner whose influence is enormous within professional networks but whose public profile is deliberately limited.

Common Mistakes to Avoid When Engaging with Tax Thought Leadership

The first and most common mistake is treating thought leadership as a substitute for professional advice. The voices on this list are producing frameworks, research, and analysis that should inform how you think about your tax situation. They are not producing advice tailored to your specific circumstances. The gap between understanding the intellectual landscape and knowing what to do in a specific situation is significant, and crossing it requires a qualified advisor who knows your facts.

The second mistake is following only voices who confirm what you already believe. Tax policy is genuinely contested, and the most valuable thing a thought leadership diet can do is expose you to rigorous arguments on multiple sides. If you find that every voice you follow reaches the same conclusions on questions like wealth taxes, transfer pricing enforcement, and the appropriate corporate tax rate, you are probably missing important perspectives. The list above deliberately includes voices with fundamentally different views on what good tax policy looks like.

The third mistake is treating geographic specificity as a limitation. The best international tax thinking often comes from voices whose primary focus is a single jurisdiction, because that focus produces genuine depth rather than superficial global coverage. A US CFO can learn as much from following Kim G C Moody on Canadian private enterprise tax planning as from following a global commentator, because the specific challenges Moody engages with illuminate structural questions that arise everywhere.

The fourth mistake is assuming that the most followed voices are the most credible. The tax advisory field has a structural public profile problem: the genuinely best advisors, those serving the largest corporate and private clients, often operate under client confidentiality obligations that prevent them from posting publicly. The voices on this list have made a specific choice to engage publicly, which is valuable, but it is a subset of the field's genuine expertise, not a proxy for it.

The fifth mistake is engaging with tax thought leadership reactively rather than proactively. The most valuable time to follow these voices is not when a tax change directly affects you. It is the months and years beforehand, when the intellectual frameworks that eventually become legislation are being developed and debated. The practitioners and researchers on this list are working at the frontier of where tax policy is going, not just describing where it has been.

Implementation Guide: Building Your Tax Thought Leadership Practice

Start by identifying which of the eight categories on this list is most directly relevant to your current role or situation. If you are a CFO or head of tax at a multinational, the corporate tax strategy and transfer pricing categories deserve your primary attention. If you are a high net worth individual or family office director, the private client advisory and tax policy categories will serve you best. If you are working in or around the tax advisory profession, the journalism, technology, and reform advocacy categories provide the broadest view of where the field is heading.

Follow the individuals you identify on LinkedIn, where most of the people on this list post regularly. The tax advisory space on LinkedIn is smaller and more technically substantive than most professional domains, which means signal-to-noise ratios are better. Set aside 15 minutes per week to read what the people you follow are posting. This is not research time. It is awareness time. The goal is not to become an expert in transfer pricing or Pillar Two. The goal is to stay calibrated about what the most credible voices are watching, worrying about, and working on.

Subscribe to Tax Notes or International Tax Review if you want deeper engagement with the specialist press. Both publications cover developments that LinkedIn posts summarise but rarely fully explain. For US-focused practitioners, Tax Notes Today provides a daily briefing that is more technically complete than any secondary source. For international practitioners, ITR's coverage of Pillar Two, transfer pricing, and jurisdiction-specific developments is genuinely irreplaceable.

Engage with what you read. The thought leaders on this list post publicly because they value the professional conversation that engagement generates. Commenting with a genuine question or a specific observation, rather than a generic endorsement, is both more valuable to the conversation and more likely to lead to direct engagement. Several of the mid-tier voices on this list, including Zofia Mika, Kim G C Moody, and Cory Litzenberger, are genuinely accessible to practitioners who engage thoughtfully with their public work.

Use what you read to inform your conversations with your own advisors. The practitioners on this list are not your advisors. But understanding the frameworks they use, the risks they are watching, and the reforms they anticipate should equip you to ask better questions of the professionals who are responsible for your specific situation.

Frequently Asked Questions

What is the difference between corporate tax and high net worth tax advisory?

Corporate tax advisory focuses on the tax obligations and planning opportunities of companies, including multinationals with complex cross-border structures, transfer pricing arrangements, and exposure to Pillar Two. High net worth tax advisory focuses on the tax planning needs of wealthy individuals and families, including estate planning, succession structures, cross-border personal tax obligations, and the tax implications of major liquidity events like business sales. The two disciplines overlap when a high net worth individual is also the owner or controlling shareholder of a privately held business, which is the context where the most complex planning challenges typically arise.

Who are the best tax thought leaders to follow on LinkedIn?

The answer depends on your specific context. For UK private client and corporate tax, Dan Neidle at Tax Policy Associates and the active UK practitioner community are the most consistent and credible voices. For Canadian tax planning, Kim G C Moody at Moodys Private Client is the most prolific and accessible independent voice. For US tax policy and corporate planning, Tony Nitti at EY, Damien Martin at EY, and the Tax Notes editorial team provide the most technically reliable coverage. For international tax policy and reform, Gabriel Zucman, Alex Cobham, and Chye-Ching Huang at the NYU Tax Law Center offer the most rigorous public analysis.

What is Pillar Two and who should I follow to understand it?

Pillar Two is the OECD's global minimum tax framework, requiring multinational enterprises with annual revenues above 750 million euros to pay a minimum effective tax rate of 15 percent regardless of where profits are booked. It came into force in more than 140 jurisdictions from 2024 and continues to be implemented and refined. To understand it, follow Manal Corwin at the OECD, whose team is responsible for the ongoing technical development of the rules, and the practitioner voices at EY, KPMG, and Grant Thornton who are publishing practical guidance on implementation. For the policy debate around whether 15 percent is the right rate and how the rules should evolve, Gabriel Zucman and Alex Cobham at the Tax Justice Network offer the most analytically rigorous critical perspective.

What are the most important tax issues for high net worth individuals in 2026?

The most important issues in 2026 include the estate planning implications of the One Big Beautiful Bill Act's permanent extension of the 15 million dollar estate tax exemption per individual in the US, the UK government's reform of non-domicile taxation and its implications for internationally mobile high net worth individuals, the ongoing European wealth tax debate shaped by Gabriel Zucman's G20 blueprint, the growing complexity of cross-border personal tax obligations for globally mobile individuals, and the increasing use of AI tools in the planning and compliance process. Tara Popernik at LPL, Greg Limb at KPMG, and the private client advisory voices on this list address these issues most consistently and accessibly.

How was this list compiled?

This directory was assembled through comprehensive research across ITR's annual Global Tax 50 rankings, academic institution faculty lists at leading law and economics programmes globally, conference speaker registers from major forums including the OECD, Taxand Global, and the Amsterdam Tax Strategies Forum, and sustained review of LinkedIn and podcast activity across the tax profession in 2025 and 2026. Candidates were assessed on formal credentials in the field, geographic and disciplinary diversity, genuine contribution to how the field has evolved, and active participation in professional conversations. The editorial team deliberately moved past household names that appear on every other list to surface voices the reader may not yet have encountered, with particular attention to mid-career practitioners building independent public profiles and researchers whose work is shaping the policy agenda.

Final Thoughts

The most important insight this list can leave you with is that tax strategy is not a technical backwater. It is one of the most consequential policy and practice arenas in the world, touching questions of corporate governance, national sovereignty, economic inequality, and democratic accountability simultaneously. The people on this list have chosen to engage with those questions publicly, at genuine professional risk in some cases, because they believe that better public understanding of tax produces better outcomes for everyone.

Whether you are a CFO navigating Pillar Two, a private client advisor working with a family office on succession planning, a finance minister trying to understand what reform is possible, or simply a curious professional who wants to understand why the tax system works the way it does, following these voices consistently is one of the highest-leverage intellectual habits you can develop. The field moves fast. The technical rules change constantly. But the frameworks, the debates, and the underlying questions remain remarkably stable, and the people on this list are your best guides to both.

Next Read: 35 Essential Thought Leaders in Wealth Management

Most conversations about wealth management happen behind closed doors. In private bank offices, in client meeting rooms, in advisor study groups that take decades to build. The thinking that shapes how hundreds of millions of people protect, grow, and transfer their wealth is generated by a relatively small community of practitioners, educators, and innovators who do the hard public work of questioning assumptions, testing frameworks, and sharing what they find.

In 2026, knowing who those people are, and following their work consistently, is one of the most practical things any financial services professional, advisor, or investor can do. The challenge is that the wealth management thought leadership ecosystem has an echo chamber problem: the same names circulate endlessly on the same lists, and genuinely fresh voices building momentum in the mid-tier get overlooked.
