50 Essential Tax Strategy Thought Leaders in the USA (2026)

Last updated: June 2026

The most important voices shaping tax strategy in the United States right now are not the ones you will find recycled across every generic list. They are the economists rebuilding how governments think about corporate taxation, the journalists translating dense legislative text into actionable intelligence, the practitioners helping business owners keep more of what they earn, and the advocates challenging assumptions about who the tax code actually serves. As of June 2026, knowing who these people are gives any leader, CFO, or tax professional a genuine edge in a year when the tax landscape is shifting faster than at any point since the Tax Reform Act of 1986.

This directory was compiled to surface the 50 voices doing the most consequential public work on tax strategy in the United States in 2026. They span corporate tax, estate planning, small business strategy, digital assets, state and local tax, and the policy architecture that shapes every planning decision. What they share is a commitment to engaging with the public conversation rather than confining their thinking to client-only channels.

If your organisation needs help navigating the people and leadership challenges that come with major tax transformation, whether building alignment around a new operating model, improving how decisions get made under uncertainty, or facilitating the executive conversations that turn external thinking into internal action, email jonno@consultclarity.org. Jonno White, author of Step Up or Step Out (10,000+ copies sold) and Certified Working Genius Facilitator, works with corporates, nonprofits, and schools around the world.

Why 2026 Is a Pivotal Year for US Tax Strategy

The enactment of the One Big Beautiful Bill Act in July 2025 permanently extended most of the Tax Cuts and Jobs Act provisions, raised the estate tax exemption to $15 million per individual, and reshaped international tax rules, renaming GILTI as Net CFC Tested Income (NCTI) and FDII as foreign-derived deduction eligible income.

According to the BDO 2026 Tax Strategist Survey, 30% of senior tax leaders now cite regulatory complexity as their single greatest enterprise tax risk, more than double the 13% who said the same in 2025. At the same time, the Urban-Brookings Tax Policy Center estimates that the top 1% of earners will receive a substantially disproportionate share of the tax cuts enacted in 2025. Knowing who is shaping the thinking on these issues, and what they are saying, has never mattered more.

For organisations looking to improve how their leadership teams communicate about tax strategy and make decisions in complex environments, engage Jonno White at jonno@consultclarity.org.

How This List Was Compiled

This directory was assembled through research across Tax Foundation rankings, Urban-Brookings Tax Policy Center publications, Tax Notes editorial contributions, conference speaker registers at the Tax Council Policy Institute, AICPA conferences, and the annual TCPI symposia, plus sustained review of LinkedIn and published output across the US tax profession in 2025 and 2026. Candidates were assessed on their documented expertise in tax strategy, the quality and consistency of their public contribution, disciplinary and geographic diversity across the United States, and active engagement with the professional conversation in 2025 and 2026.

Category 1: Policy Architects

The policy architects are the researchers, analysts, and think tank leaders who define the intellectual framework within which every tax planning decision gets made. Their models, reports, and congressional testimony shape legislation before it becomes law. The Tax Foundation and the Urban-Brookings Tax Policy Center are the two most-cited independent organisations shaping the US federal tax policy debate. The analysts working from these institutions occupy a unique position: they are credentialed, independent, and publicly accessible in ways that the Big 4 firms are not.

1. Erica York

As Vice President of Federal Tax Policy at the Tax Foundation's Center for Federal Tax Policy, Erica York is one of the most active and publicly visible federal tax analysts working in the United States today. Her analysis covers the distributional effects of income tax changes, tariff policy, and the interaction between federal and state tax systems. In 2026, her modelling of the One Big Beautiful Bill Act's household-level effects was widely cited in major media outlets including The Wall Street Journal, The Washington Post, and Politico, establishing her as a primary reference point for journalists and policymakers navigating a complex legislative environment. She posts original analysis consistently on LinkedIn, making her work accessible to a broad professional audience.

York's commentary is distinguished by its combination of rigour and accessibility. Her ability to translate economic modelling outputs into clear policy implications, without sacrificing technical accuracy, places her in a rare category of analysts who are equally useful to a policymaker and to a CFO trying to understand what a new law means for their organisation. Her work on the tariff's household cost in 2026 provided one of the most-cited estimates of the consumer cost of trade policy.

2. Garrett Watson

As Director of Policy Analysis at the Tax Foundation, Garrett Watson conducts research on both federal and state tax policy, with a particular focus on how tax systems interact at multiple levels of government. His work has been featured in The Washington Post, The Atlantic, Politico, and the Associated Press, and his LinkedIn activity reflects a professional commitment to public-facing analysis rather than firm-internal research. Watson's analysis of how state governments responded to the conformity challenges created by the One Big Beautiful Bill Act has been particularly valuable in 2025 and 2026.

Watson's contribution is most visible at the intersection of federal and state tax policy, a genuinely underserved area of public analysis. When federal legislation changes the base on which state taxes are calculated, states face decisions about conformity that have major fiscal consequences. Watson's ability to track those decisions across multiple jurisdictions simultaneously and make the implications legible for practitioners and policymakers sets him apart as a consistently useful voice.

3. Kyle Pomerleau

Now a resident fellow at the American Enterprise Institute, Kyle Pomerleau was previously Chief Economist at the Tax Foundation, where he led the macroeconomic modelling team. His research at AEI covers corporate taxation, international tax policy, and the economic effects of the OBBBA provisions that came into force in 2025 and 2026. He has been frequently quoted in The New York Times, The Wall Street Journal, and The Washington Post, and has testified before Congress and state legislatures on tax reform. His analysis of how the OBBBA affects the distribution of income tax burdens across households, finding that roughly 60% of tax units will receive an average 2025 tax cut of nearly $1,200, was widely circulated in policy circles.

Pomerleau's transition from Tax Foundation to AEI reflects a broader shift in how independent tax economists move between think tanks, each with a distinct ideological orientation, while maintaining technical credibility across the policy spectrum. His willingness to engage critically with proposals from both sides of the aisle, offering clear-eyed modelling rather than advocacy, makes his work a useful benchmark for anyone assessing tax policy claims.

4. Howard Gleckman

A nonresident fellow at the Urban-Brookings Tax Policy Center and a regular contributor to Forbes.com, Howard Gleckman is one of the most experienced tax policy communicators in the United States. He was the founding editor of TaxVox, the Tax Policy Center's fiscal policy blog, and spent nearly 18 years at Urban before transitioning to a visiting fellow role. His decades covering fiscal policy as a senior correspondent at Business Week, where he was a 2003 National Magazine Award finalist, give his work a journalistic clarity that distinguishes it from purely academic output.

Gleckman's Forbes columns on tax policy and aging issues are read by a broad professional audience that extends well beyond the tax specialist community. His ability to explain complex distributional effects, such as who actually benefits from SALT deduction changes or how estate tax rule modifications affect planning, in language accessible to a financially literate generalist audience makes him an invaluable gateway into tax policy analysis for senior leaders who need to understand the implications of legislative change without a background in tax economics.

5. Len Burman

The co-founder of the Tax Policy Center, co-author with Joel Slemrod of Taxes in America: What Everyone Needs to Know, and currently the Paul Volcker Chair of Behavioral Economics at the Maxwell School of Syracuse University and Director of the Tax Policy Center, Len Burman is one of the foundational figures in American tax policy analysis. He served as Deputy Assistant Secretary for Tax Analysis at the US Treasury from 1998 to 2000 and as a Senior Analyst at the Congressional Budget Office, giving him a rare combination of institutional experience and academic depth. He is past president of the National Tax Association and has testified before Congress on numerous occasions.

Burman's particular contribution is the framing of tax policy as a question of trade-offs that affects ordinary people, not just high-income households or corporations. His book with Slemrod, first published and updated across multiple editions, remains one of the most widely read accessible guides to the American tax system for a general professional audience. His work on capital gains tax policy has directly influenced legislative debates, and his continued engagement with congressional testimony in 2025 and 2026 reflects a career-long commitment to translating rigorous research into policy-relevant communication.

6. Steve Wamhoff

As Director of Federal Tax Policy at the Institute on Taxation and Economic Policy, Steve Wamhoff leads the organisation's analysis of federal tax legislation with a particular focus on distributional effects and corporate tax reform. ITEP is one of the few organisations in the US that produces granular state-by-state and income-group analysis of the effects of tax proposals, and Wamhoff's work anchors that analytical program. His analysis of the OBBBA, published in July 2025, was among the most-cited progressive tax policy responses to the legislation, providing detailed modelling of who gains and who pays under the new regime.

Wamhoff's public communication is consistently clear, technically grounded, and explicitly oriented toward the policy implications for working and middle-income households. His willingness to engage with the media and translate ITEP's microsimulation models into accessible commentary makes him one of the more useful voices for a generalist professional audience seeking to understand the redistributive effects of major tax legislation.

7. Chye-Ching Huang

As Executive Director of the Tax Law Center at New York University School of Law, Chye-Ching Huang leads one of the most technically rigorous independent tax policy research organisations in the country. The Tax Law Center focuses specifically on the quality and integrity of the tax rulemaking process, publishing detailed legal and technical analysis of IRS guidance, Treasury regulations, and the interaction between legislation and administrative implementation. Her background includes senior positions at the Center on Budget and Policy Priorities, where she developed expertise in tax policy and its intersection with income security.

Huang's contribution to the public conversation is distinctive because it focuses on the nuts and bolts of how tax law actually gets implemented, not just what it says on paper. When major legislation like the OBBBA is enacted, the real-world effect on taxpayers depends heavily on how Treasury and the IRS interpret and implement it through regulations and guidance. The Tax Law Center's work on this implementation layer is a resource that practitioners, academics, and advocates across the political spectrum rely on.

8. Donald Marron

An Institute Fellow and Director of Economic Policy Initiatives at the Urban Institute, Donald Marron is a former Acting Director of the Congressional Budget Office and has served on the President's Council of Economic Advisers. His work at Urban covers tax policy, budget policy, and economic research with a particular focus on fiscal responsibility and the long-term trajectory of federal finances. His engagement with questions around tax expenditures, corporate taxation, and the interaction between tax policy and social policy reflects a career that bridges government service and independent research.

Marron's institutional experience at the highest levels of federal economic policymaking gives his analysis a practical orientation that complements the modelling work of younger analysts at TPC and the Tax Foundation. His ability to frame tax policy questions in terms of long-run fiscal sustainability is particularly relevant in 2026, when the OBBBA's permanent extension of TCJA provisions has raised new questions about the long-term federal revenue trajectory.

Category 2: Academic Economists and Tax Scholars

The academic economists on this list produce the research that eventually shapes legislation, court decisions, and professional practice. Their work operates on a longer time horizon than the think tank analysts in Category 1, but its influence is no less real. Several of these scholars have also built substantial public platforms that make their technical work accessible well beyond specialist journals.

9. Joel Slemrod

The David Bradford Distinguished University Professor of Economics at the University of Michigan and Director of the Office of Tax Policy Research, Joel Slemrod is one of the most widely cited tax economists in the world, with over 43,000 citations on Google Scholar. His research covers the impact of tax systems on behaviour, tax compliance, and the political economy of tax policy. He is co-author with Len Burman of Taxes in America: What Everyone Needs to Know and co-author with Michael Keen of Rebellion, Rascals, and Revenue: Tax Follies and Wisdom through the Ages, published by Princeton University Press in 2021. He served as Senior Economist for Tax Policy on the President's Council of Economic Advisers and as Editor of the National Tax Journal.

Slemrod's particular contribution is the integration of behavioural economics with tax analysis, drawing attention to how taxpayers actually respond to tax rules rather than how economists assume they will. His research on tax compliance, including the use of IRS administrative data to understand what actually drives reporting behaviour, has practical implications for both tax administration and tax planning strategy. His 2026 paper in International Tax and Public Finance, co-authored with several colleagues, examining how taxes affect economic growth across countries, represents his continuing contribution to one of the most contested questions in the field.

10. Raj Chetty

The William A. Ackman Professor of Public Economics at Harvard University and founder of Opportunity Insights, Raj Chetty is one of the most celebrated empirical economists in the world. His research on tax policy, intergenerational mobility, and the effects of place on economic outcomes has been cited in media coverage from The New York Times to the Economist, and he has testified before Congress on tax and social policy. His work using administrative tax data to track economic mobility across generations has fundamentally shifted how researchers and policymakers think about the relationship between the tax system and economic opportunity.

While Chetty's work spans many policy domains beyond tax, his use of IRS data to produce some of the most rigorous analysis of how the tax system affects different income groups gives his research direct relevance for tax strategy practitioners and policymakers. His findings on how opportunity varies by geography, race, and family income have informed debates about the distributional fairness of the US tax code. For CFOs and policy professionals who want to understand the evidence base behind tax equity arguments, Chetty's research is foundational.

11. Michelle Hanlon

Professor of Accounting at the MIT Sloan School of Management and a former academic fellow with the US House Ways and Means tax staff, Michelle Hanlon has testified before the US Senate Committee on Finance and the US House Ways and Means Committee on US tax policy. Her research addresses the interaction of tax policy and financial reporting, corporate tax compliance, and how firms respond to tax law changes. Her academic work straddles the boundary between public economics and accounting, making her contribution particularly relevant for practitioners in corporate tax functions who need to understand how research findings translate into compliance and planning decisions.

Hanlon's testimony before congressional committees reflects a rare combination of technical depth and willingness to engage directly with the legislative process. Her research on how public disclosure of corporate tax information affects firm behaviour has direct implications for the growing policy debate around corporate tax transparency, which accelerated in 2025 and 2026 under pressure from Pillar Two implementation in other jurisdictions. Her continued engagement with both academic publications and congressional testimony in 2025 makes her one of the most directly policy-relevant tax accounting scholars in the United States.

12. Jeff Hoopes

Research Director of the University of North Carolina Tax Center and Professor of Accounting at UNC, Jeff Hoopes studies how taxpayers respond to tax laws and changes in tax enforcement. His research draws on empirical methods to examine issues at the intersection of accounting, public economics, and finance, covering both corporate and individual taxation as well as tax administration and compliance. His work on how increased IRS scrutiny of specific taxpayer populations affects compliance behaviour has direct implications for corporate tax risk management.

Hoopes occupies a valuable position in the academic landscape as a researcher whose work is both technically rigorous and directly oriented toward practitioner-relevant questions. His leadership of the UNC Tax Center, one of the most active university-based tax research organisations in the country, also means that his influence extends beyond his individual publications to the pipeline of tax policy research that the Center produces and disseminates through conferences and working paper series.

13. Annette Nellen

Professor and Director of the Graduate Tax Program at San Jose State University, Chair of the AICPA Digital Assets Tax Task Force, member of the IRS Advisory Council (IRSAC, reappointed for a fourth year in late 2025), and the only accounting and tax professor named to Accounting Today's Top 100 Most Influential People in Accounting for both 2024 and 2025, Annette Nellen stands at the intersection of academic tax education, professional standards, and emerging technology. Her 21st Century Taxation blog and website make her one of the most publicly accessible tax educators in the country, and her regular column for Tax Notes State covers state and local tax developments with clarity and rigour.

Nellen's combination of roles is unusual and valuable. Her work with the AICPA Digital Assets Tax Task Force, which she chaired through the critical period of Form 1099-DA implementation in 2025, makes her the clearest academic voice on the tax treatment of cryptocurrency and digital assets in the US professional community. Her testimony before the House Ways and Means Committee, Senate Finance Committee, and multiple state bodies on cryptocurrency, worker classification, and tax reform positions her as one of the most directly policy-engaged academic tax professionals in the country.

14. Emmanuel Saez

A Professor of Economics at UC Berkeley and one of the most prominent researchers on inequality and taxation in the world, Emmanuel Saez co-created with Gabriel Zucman the wealth inequality measurement methodology that has reshaped how economists understand income and asset distribution. 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. In 2025, he published research using IRS administrative data that provided empirical grounding for billionaire tax rate analysis, and in 2026 he co-drafted the California Billionaires Tax Act initiative alongside Brian Galle, David Gamage, and Darien Shanske.

Saez's work is among the most politically consequential academic research in the US tax debate. His collaboration with the World Inequality Database, his methodological contributions to measuring wealth concentration, and his willingness to translate research into specific legislative proposals make him a distinctive voice: a technically rigorous academic who also functions as a public intellectual and policy advocate. Whether one agrees with his conclusions or not, understanding his evidence base is essential for anyone engaged with the US tax equity debate.

15. Kimberly Clausing

The Eric M. Zolt Professor of Tax Law and Policy at UCLA School of Law and a former Deputy Assistant Secretary for Tax Analysis at the US Treasury during the Biden administration, Kimberly Clausing brings both academic rigour and government experience to the US corporate and international tax policy debate. Her research covers how multinational corporations respond to tax incentives, profit shifting, and the design of international tax rules. She is the author of Open: The Progressive Case for Free Trade, Immigration, and Global Capital, which situates US tax policy within a broader framework of international economic integration.

Clausing's Treasury experience gives her analysis an insider's understanding of how tax rules are actually designed and administered in practice, which distinguishes her from purely academic contributors. Her post-Treasury return to UCLA has been marked by continued engagement with the international tax policy debate, including her analysis of how the OBBBA's changes to NCTI and FDDEI affect US companies' incentives relative to the OECD Pillar Two framework.

Category 3: Journalists and Media Voices

The journalists and editors on this list do something that no research organisation or practitioner can replicate: they produce the primary record of what is actually happening in US tax policy and practice, in real time. Their coverage translates legislative developments, court decisions, and regulatory guidance into intelligence that practitioners rely on daily.

16. Richard Rubin

The US tax policy reporter for The Wall Street Journal in Washington, Richard Rubin has covered tax policy since 2007 and worked for Bloomberg News and Congressional Quarterly before joining the Journal in 2015. He was the lead author on the Journal's coverage of the 2017 Tax Cuts and Jobs Act and has covered every major tax development since, including the OBBBA in 2025. His LinkedIn activity and consistent output across 2025 and 2026 reflect a journalist who is as accessible as he is technically proficient.

Rubin occupies a singular position in US tax journalism. The Wall Street Journal's tax coverage is read by the senior executives, CFOs, and boards who make the major decisions that tax strategy shapes. His ability to translate congressional negotiations, Treasury rulemaking, and IRS enforcement priorities into clear, actionable reporting means that his byline has a direct influence on how the business community understands and responds to tax developments.

17. Lee A. Sheppard

A contributing editor at Tax Notes and one of the most technically authoritative and independently minded voices in US tax journalism, Lee A. Sheppard has been writing about federal and international tax developments for Tax Notes for decades. Her coverage of transfer pricing, international tax policy, and corporate tax avoidance is characterised by a willingness to name problems directly and challenge conventional practice in a way that is rare in a field where most technical commentary is produced by practitioners with a stake in the outcome.

Sheppard's contribution to the field is both informational and institutional. Her consistent engagement with the technical minutiae of international tax rules, combined with her willingness to take and defend strong analytical positions, has shaped how practitioners, academics, and regulators think about the boundaries of legitimate tax planning. Her commentary on Pillar Two implementation, CAMT, and the OBBBA's changes to the international tax framework has been essential reading for corporate tax professionals navigating the 2025 and 2026 legislative environment.

18. Robert Goulder

A contributing editor at Tax Notes and a veteran tax journalist, Robert Goulder specialises in coverage of international tax developments, with particular depth in transfer pricing, Pillar Two, and the intersection of trade and tax policy. His work draws on decades of reporting from inside the specialist tax community and his coverage of the OBBBA's international provisions has been widely cited in practitioner publications. His podcast appearances and conference speaking extend his reach beyond Tax Notes' readership into the broader practitioner and advisory community.

Goulder's journalism is particularly valuable for practitioners and executives working in multinational environments, where the gap between understanding what a law says and understanding its practical implications in cross-border contexts is enormous. His ability to cover the technical complexity of provisions like BEAT, GILTI's rebranding as NCTI, and the Section 899 developments in 2025, in a way that is accessible to non-specialists, makes him one of the more practically useful tax media voices in the country.

19. Marie Sapirie

A senior editorial contributor at Tax Notes, Marie Sapirie covers exempt organisations, corporate tax developments, and the intersection of tax and governance. Her May 2025 article on Harvard University's fight to retain its tax-exempt status, which prompted a response from multiple law professors including Brian Galle, Philip Hackney, and Ellen Aprill, is an example of the kind of technically grounded investigative tax journalism that Tax Notes produces under her byline. Her engagement with one of the most consequential tax law stories of 2025 reflects both her depth of expertise and her willingness to address politically sensitive material with rigour.

Sapirie's contribution to the public tax conversation is important because the exempt organisation space, encompassing universities, hospitals, foundations, and advocacy organisations, is one of the most politically contested and least publicly understood areas of US tax law. Her coverage makes a specialist topic legible for a broader audience of executives, board members, and policymakers who need to understand the rules governing nonprofit governance and taxation.

20. David D. Stewart

Editor in Chief of Tax Notes Today International and host of the Tax Notes Talk podcast, David D. Stewart is one of the most recognisable public voices in US tax media. His podcast, which features regular conversations with the Tax Notes editorial and contributor team as well as external experts, has become a primary format through which the specialist tax community communicates developments in international and domestic tax law to a practitioner audience. His interviews on the OBBBA's international implications, Pillar Two developments, and IRS enforcement priorities in 2025 and 2026 have reached audiences well beyond Tax Notes' traditional subscriber base.

Stewart's role as both editor and podcast host gives him an unusual influence over the public tax conversation. By choosing which topics to cover and which contributors to feature, he shapes the agenda of what the US and international tax professional community considers important. His consistent engagement with both technical and policy aspects of the tax landscape in 2025 and 2026 reflects a genuine editorial commitment to the kind of in-depth specialist coverage that the profession needs.

21. Kelley Taylor

Senior editor covering taxes and personal finance at Kiplinger, Kelley Taylor brings more than two decades of experience at the intersection of education, law, finance, and tax to her public-facing work. Her background as both a corporate attorney at Ernst and Young, where she focused on compensation and benefits tax and tax-exempt organisations, and as a former writer for Tax Notes Today, where she covered sophisticated tax issues involving partnerships, carried interest, and high net worth individuals, gives her analysis unusual depth for a consumer-facing publication. Her coverage of the OBBBA's practical implications for individual and small business filers has been some of the most widely read accessible tax analysis published in 2025 and 2026.

Taylor's contribution is particularly important for the segment of tax thought leadership most often underserved by specialist publications: the educated individual taxpayer, small business owner, or financial advisor who needs to understand what major tax changes mean for their situation without having a specialist tax law background. Her ability to translate legislative complexity into clear, actionable analysis for this audience, drawing on genuine technical depth, makes her one of the more valuable translators in the US tax media landscape.

Category 4: Large Firm and Institutional Practitioners

The large firm practitioners on this list hold senior positions at the Big 4 and national accounting firms with specific responsibility for thought leadership and public engagement. They represent the practitioner knowledge layer that translates policy developments into client guidance at scale.

22. Doug McHoney

PwC's International Tax Services Global Leader and host of the Cross-Border Tax Talks podcast, Doug McHoney is one of the most publicly visible practitioners in US international tax strategy. His podcast, co-hosted with senior colleagues including Pat Brown, covers the most significant international tax developments affecting US multinationals in real time. His January 2026 episode reviewing the OBBBA's international provisions, Pillar Two's evolving architecture, and the implications of the OECD's updated global minimum tax framework provided one of the most comprehensive practitioner-level briefings available on the post-OBBBA international landscape.

McHoney's public platform is distinctive among Big 4 practitioners because it is genuinely technical and substantive rather than purely promotional. His willingness to engage critically with the complexity of provisions like CAMT corrections, stock buyback excise tax guidance, and the implications of long-awaited Section 987 rules reflects a commitment to practitioner education that extends beyond client development.

23. Pat Brown

A Partner and Co-leader of PwC's National Tax Office in Washington, and former General Electric VP of Tax and Director of Tax Policy, Pat Brown brings a rare combination of large company in-house experience and Big 4 advisory leadership to his public work. His co-hosting role on the Cross-Border Tax Talks podcast and his regular analysis of international tax developments for PwC's corporate client base position him as one of the more credible voices on the practical implications of US international tax rules for multinational enterprises. His analysis of how the OBBBA's changes to NCTI, FDII (now FDDEI), and CAMT affect the effective tax rate planning of major US companies has been widely circulated among corporate tax departments.

Brown's particular value is his ability to bridge the policy design world, where he engaged during his GE years and his work with PwC's Washington National Tax Services, and the practical implementation world where large corporate tax departments operate. This dual perspective makes his commentary more directly actionable for CFOs and VPs of Tax than the work of policy analysts who have not spent significant time in corporate tax functions.

24. Dustin Stamper

As Managing Director of Tax Legislative Affairs at BDO USA, Dustin Stamper tracks, interprets, and communicates major tax legislative developments to BDO's client base. His 2026 articles in BDO's tax intelligence series on planning priorities post-OBBBA, which addressed how the legislation affects pass-through entities, real estate, and corporate taxpayers, were among the most practically useful pieces of planning guidance published by a national firm. His LinkedIn activity and consistent publication record in 2025 and 2026 reflect a practitioner committed to public-facing communication rather than internal-only advisory work.

Stamper's contribution is most visible in the middle market, where BDO focuses its practice. The planning implications of major tax legislation are often more complex for middle market companies than for the Fortune 500, because middle market businesses lack the internal tax department resources to absorb and implement legislative change at scale. Stamper's work translating legislative developments into middle market planning priorities fills a genuine gap in the practitioner communication landscape.

25. Jamie Yesnowitz

A Partner and the State and Local Tax (SALT) Leader within Grant Thornton's Washington National Tax Office, Jamie Yesnowitz leads one of the most technically authoritative SALT practices in the country. His team's annual SALT outlook predictions, published each February, are among the most-read state and local tax publications in the practitioner community. His 2026 SALT outlook, which addressed how states were responding to OBBBA conformity questions, the expansion of bonus depreciation, and international tax rule changes at the state level, provided a comprehensive map of the SALT implications of the federal legislative changes for multistate businesses.

SALT is an area where the complexity-to-public-understanding ratio is among the highest in US tax strategy. The interaction between federal tax changes and fifty different state tax regimes, each with its own conformity rules and policy priorities, creates a planning environment that is genuinely difficult to navigate without specialist guidance. Yesnowitz's work making this complexity legible for practitioners and corporate tax departments is a genuine public service.

26. Aruna Kalyanam

As EY's Global and Americas Tax Policy Leader, Aruna Kalyanam presents and communicates EY's annual Tax Policy and Controversy Outlook series, which provides analysis of the major drivers shaping tax policy and controversy globally and in the Americas. Her 2026 series, which identified three major structural drivers shaping the global tax environment, including government revenue pressures, Pillar Two implementation, and the acceleration of digital enforcement, reached audiences well beyond EY's client base through conference appearances, webcast series, and social media distribution.

Kalyanam's role at the intersection of EY's global tax practice and the external policy conversation gives her analysis a real-time quality that think tank researchers, operating on longer publication timelines, cannot replicate. Her ability to draw on EY's global network of tax professionals while translating their collective intelligence into publicly accessible briefings makes her one of the more valuable institutional voices in the US tax strategy landscape.

Category 5: Entrepreneur and Small Business Tax Educators

The entrepreneur and small business tax educators on this list have built public platforms specifically to help business owners and high earners understand and reduce their tax burden legally. They occupy a different part of the thought leadership spectrum from the policy analysts and academics, but their influence on how millions of American business owners think about and act on their tax situation is enormous.

27. Tom Wheelwright

The CEO of WealthAbility, author of Tax-Free Wealth (now in its third edition) and The Win-Win Wealth Strategy, and a Rich Dad Advisor to Robert Kiyosaki, Tom Wheelwright is one of the most widely read and followed tax strategy voices for entrepreneurs and investors in the United States. His books have sold widely and his podcast The WealthAbility Show has built a substantial audience. His approach, which argues that tax laws are designed primarily as incentive systems for the behaviour governments want to encourage rather than as burdens to be minimised, reframes how entrepreneurs think about the relationship between tax planning and business strategy.

Wheelwright's most concrete contribution is The Win-Win Wealth Strategy, which reached number four on the Wall Street Journal bestseller list, in which he maps out seven investment categories that the US government actively incentivises through the tax code, including real estate, energy, qualified opportunity zones, and small business. For business owners who have not engaged deeply with the incentive structure embedded in the tax code, this framework provides a practical entry point into proactive tax planning that extends well beyond compliance and deduction harvesting.

28. Mike Jesowshek

The CPA, entrepreneur, and founder of TaxElm and host of the Small Business Tax Savings Podcast, Mike Jesowshek has built one of the most practically useful free resources for small business owners navigating US tax strategy. His podcast breaks down complex tax concepts, from entity structure selection to the meal and travel deduction rules under the OBBBA, into clear guidance for business owners who are not tax specialists. His LinkedIn activity in 2025 and 2026 reflects consistent original content on the planning implications of legislative changes for small business owners.

Jesowshek's contribution is most significant in democratising access to proactive tax planning for business owners who cannot afford specialist advisory fees. His TaxElm platform translates professional-grade tax planning strategies into a format that a business owner with no accounting background can act on, which directly addresses the gap between what the tax code makes available and what most small business owners actually claim.

29. Jackie Meyer

The co-founder and President of TaxPlanIQ, entrepreneur, speaker, and former boutique CPA firm founder who grew and sold her firm for seven figures, Jackie Meyer has become one of the most influential voices in the US tax advisory profession. Named by CPA Practice Advisor as one of the Most Powerful Women in Accounting in 2025, her work with TaxPlanIQ, a SaaS platform built to make professional-grade tax planning accessible to more practitioners and their clients, represents a structural contribution to how tax strategy gets delivered in the American small and medium business market.

Meyer's March 2026 guide to cryptocurrency and digital asset tax strategy for tax year 2026, which addressed Form 1099-DA reporting, broker reporting rules, stablecoin regulation, and the CARF international reporting coordination framework, established her as one of the more authoritative practical voices on digital asset tax planning at the practitioner level. Her willingness to address technically complex topics in accessible formats for both advisors and clients is a distinguishing characteristic of her public contribution.

30. Carlotta Thompson

The founder and CEO of Tax Strategists of America and a former IRS enrolled agent, Carlotta Thompson has built her platform on a specific value proposition: helping small business owners pay the least tax legally possible by educating them about strategies that larger businesses use routinely but that small business owners rarely access. Her April 2026 appearance on The Action Catalyst podcast, where she described her career arc from studying tax law at 14 to working as an IRS auditor before founding her firm, provides a clear picture of the practitioner background that informs her public work.

Thompson's particular contribution is in making advanced tax strategy accessible to the segment of the US business community that is most frequently underserved by the tax advisory profession: small business owners with revenues below the level where the major CPA firms focus their attention. Her background as an IRS enrolled agent, where she saw repeatedly how small business owners left significant deductions on the table, gives her teaching a credibility rooted in actual observation of what goes wrong in small business tax compliance.

31. Shauna Wekherlien

Founder of Tax Goddess Business Services in Scottsdale, Arizona, CPA, Master of Tax, and ranked among the top one percent of Certified Tax Strategists in the United States by the American Institute of Certified Tax Planners, Shauna Wekherlien has built a practice and a public platform specifically around the design and implementation of comprehensive tax strategy plans for high-earning business owners and entrepreneurs. Her clients report tax rates substantially below the average for their income category, and her team has prepared over 4,700 tax strategy plans generating over two billion dollars in total client savings.

Wekherlien's public contribution is characterised by a focus on the proactive architecture of a tax strategy rather than reactive compliance. Her emphasis on helping clients understand the risk profile of various planning strategies rather than simply applying the most aggressive approach reflects a sophisticated approach to tax strategy that acknowledges the trade-offs between tax savings and audit risk. Her LinkedIn activity and podcast appearances in 2025 and 2026 reflect consistent engagement with the practitioner and client community.

32. Logan Allec

The CPA and owner of Choice Tax Relief in Santa Clarita, California, Logan Allec is a 2026 Forbes Finance Council member who has built a public profile through clear, accessible commentary on federal tax developments as they affect individual and small business filers. His quoted analysis in Yahoo Finance's February 2026 piece on the no-tax-on-tips deduction under the OBBBA illustrated his ability to translate technically complex legislative changes into clear guidance for a general financial audience. His social media activity reflects consistent engagement with the practical implications of tax law changes for working Americans.

Allec's contribution is in making the practical consequences of major federal tax changes accessible to a broad public audience in real time. While academic economists model the distributional effects of legislation and think tank analysts assess its structural properties, Allec addresses the question that most individual taxpayers and small business owners actually care about: what does this mean for my specific situation, and what should I do about it?

33. Navi Maraj

The CPA and founder of Navi Maraj CPA in West Palm Beach, Florida, Navi Maraj has built an active LinkedIn and social media presence specifically oriented toward helping realtors and small business owners understand how to legally reduce their tax burden through strategic planning. His consistent original content in 2025 and 2026, addressing topics from S-Corp and multi-member LLC tax deadlines to the warning signs of inadequate tax planning, has built a following among the small business and real estate professional communities. His direct, no-jargon communication style positions him as an accessible entry point for business owners who are new to proactive tax strategy.

Maraj's public contribution is in making the foundational concepts of proactive business tax planning accessible and engaging for an audience that traditional accounting firms often struggle to reach on social media. His willingness to address the psychological and behavioural barriers to tax planning, not just the technical details, reflects an understanding that the gap between available tax strategies and their adoption by small business owners is often a communication problem as much as a knowledge problem.

Category 6: Estate, Private Wealth, and Taxpayer Rights

The specialists in this category work at the intersection of tax strategy, wealth preservation, and the rights of taxpayers navigating an increasingly complex system. Their contribution ranges from technical expertise on estate planning structures to advocacy for better tax administration.

34. Erin Collins

The National Taxpayer Advocate, appointed in March 2020 by Treasury Secretary Mnuchin and serving continuously since, Erin Collins leads the Taxpayer Advocate Service, which functions as an independent voice for taxpayers within the IRS and before Congress. Named to Accounting Today's Top 100 Most Influential People in Accounting for four consecutive years from 2022 through 2025, and described as the 'voice of the taxpayer' inside the IRS, Collins has used the Annual Report to Congress to consistently identify systemic failures in tax administration and advocate for practical improvements.

Collins' contribution in 2025 and 2026 has been particularly significant against the backdrop of IRS staffing constraints, processing delays, and the implementation complexity created by the OBBBA. Her Fiscal Year 2026 Objectives Report, released in June 2025, highlighted successful aspects of the 2025 filing season while raising concerns about persistent refund delays for identity theft victims and the challenges facing taxpayers as the IRS prepares for the 2026 filing season with reduced staffing. Her public advocacy, including her blog post during the Kwong v. United States litigation, has directly helped taxpayers understand and claim rights they might otherwise have missed.

35. Cara Griffith

The President and CEO of Tax Analysts, the nonprofit publisher of Tax Notes and the world's largest independent nonpartisan tax news and analysis organisation, Cara Griffith leads an institution that has been the primary record of US and international tax policy and practice since 1970. Tax Notes, in its federal, international, and state editions, is read by practitioners, academics, and policymakers across the United States and internationally as the authoritative source for tax law developments. Griffith succeeded Christopher Bergin as CEO in 2017 and has led the organisation through its digital transformation and expansion into digital asset tax coverage.

Griffith's influence operates at the institutional level: the editorial standards, coverage priorities, and public service mission of Tax Analysts under her leadership determine what the tax professional community considers worth knowing and discussing. Her recognition in the Fastcase 50 as one of the most innovative legal professionals reflects the broader professional community's assessment of Tax Analysts' contribution under her leadership.

36. David Handler

A Partner in the Trusts and Estates Practice Group at Kirkland and Ellis in Chicago, David Handler is listed among the top tier in Chambers USA's Wealth Management category and in The Best Lawyers in America. He is a Fellow of the American College of Trust and Estate Counsel, a member of the NAEPC Estate Planning Hall of Fame as an Accredited Estate Planner (Distinguished), and a monthly columnist for Trusts and Estates Magazine. His regular 'Tax Law Update' columns for Wealth Management magazine provide practical, current analysis of estate and gift tax developments for a professional audience.

The OBBBA's permanent extension of the estate tax exemption at $15 million per individual fundamentally shifted the estate planning landscape for wealthy Americans. Handler's analysis of what these changes mean for trust structures, portability elections, and the interaction between estate and gift tax planning represents exactly the kind of authoritative technical guidance that high-net-worth families and their advisors need to navigate the new planning environment. His consistent public output in 2025 and 2026 reflects a practitioner committed to educating as well as advising.

37. Alison Lothes

A Partner at Gilmore, Rees and Carlson in Wellesley, Massachusetts, Alison Lothes focuses on estate planning for high net worth individuals, including estate, gift, and generation-skipping transfer tax planning, will and trust preparation, estate and trust administration, and charitable giving. Her contributions to Wealth Management magazine's 'Tax Law Update' series provide authoritative analysis of estate planning developments in accessible formats for the broader wealth management community.

Lothes's practice reflects the full complexity of post-OBBBA estate planning, including the interaction between the elevated exemption levels and the planning strategies available to families whose estates sit near or above the threshold. Her focus on the practical design of structures that serve both immediate tax minimisation goals and longer-term family wealth objectives represents the kind of integrated planning perspective that distinguishes leading estate practitioners from those focused solely on tax minimisation.

38. Nina Olson

The founder and Executive Director of the Center for Taxpayer Rights and former National Taxpayer Advocate for 18 years, Nina Olson is one of the most influential advocates for taxpayer rights in the United States. During her tenure as National Taxpayer Advocate, she built the Taxpayer Advocate Service into one of the most effective internal oversight mechanisms in federal tax administration. Since founding the Center for Taxpayer Rights in 2019, she has continued to advance taxpayer rights through education, advocacy, and international collaboration, including work on the Taxpayer Rights Charter and global dialogue about fair tax administration.

Olson's current work at the Center for Taxpayer Rights addresses the structural relationship between tax administration and taxpayer rights at a level that neither individual practitioners nor think tank analysts typically reach. Her decades of direct experience with how the IRS interacts with ordinary taxpayers, combined with her continued engagement with policy debates around IRS modernisation, enforcement priorities, and the protection of low-income taxpayers, make her a unique and invaluable voice in the US tax strategy conversation.

39. Steve Rosenthal

A Senior Fellow at the Urban-Brookings Tax Policy Center, Steve Rosenthal focuses on the taxation of corporations and their shareholders, pass-through businesses, and the interaction between the corporate and individual tax systems. His work on how the OBBBA affects the integration of the corporate and individual tax systems has been among the most technically detailed independent analysis produced on this question in 2025 and 2026. Before joining TPC, he practised tax law at Ropes and Gray.

Rosenthal's contribution bridges the academic policy analysis world and the practitioner community in a way that is relatively rare at think tanks. His background in tax law practice gives his analysis a specificity and a grounding in how rules actually work that complements the macroeconomic modelling focus of many TPC colleagues. His consistent engagement with questions around corporate tax integration, pass-through taxation, and the OBBBA's structural effects makes him one of the more technically rigorous voices in the public tax policy debate.

Category 7: Reform and Advocacy Voices

The voices in this category are shaping the broader conversation about what the US tax system should look like, rather than only analysing what it currently does. They include advocates from across the political spectrum, from anti-tax traditionalists to progressive reform advocates, as well as the recently retired economist whose analytical career helped define the field.

40. Amy Hanauer

The Executive Director of both the Institute on Taxation and Economic Policy and Citizens for Tax Justice, Amy Hanauer leads the two most influential progressive tax policy organisations in the country. Under her leadership, ITEP has produced some of the most widely-cited distributional analyses of the 2025 tax legislation, demonstrating through rigorous microsimulation modelling that the OBBBA raises taxes on the poorest 40% of Americans while delivering substantial cuts to the wealthiest households. Her communication of ITEP's research through media appearances, social media, and legislative testimony has made the distributional analysis of tax policy accessible to a broad progressive advocacy and policy audience.

Hanauer's leadership is notable for its combination of technical rigour, communications effectiveness, and explicit commitment to the relationship between tax policy and economic justice. ITEP's state-by-state analysis, which maps the distributional effects of federal tax proposals on residents of each state, is a resource that state legislators, journalists, and advocates use routinely to understand the local implications of federal legislative choices.

41. Scott Hodge

President Emeritus and Senior Policy Advisor at the Tax Foundation, which he led as President for more than two decades from 2000 to 2022, Scott Hodge is recognised as one of Washington's leading experts on tax policy, the federal budget, and government spending. His 2023 book Taxocracy: What You Don't Know About Taxes and How They Rule Your Daily Life presents the case that taxes are not merely revenue tools but structural forces that shape behaviour across every domain of American life. His continued commentary as a senior advisor to the Tax Foundation maintains his influence on the policy conversation.

Hodge's legacy contribution is in building the Tax Foundation into the most widely cited nonpartisan tax policy research organisation in the United States, developing its Taxes and Growth Model, and establishing its reputation for rigorous independent analysis. His book Taxocracy represents a popular synthesis of the behavioural and incentive arguments against tax complexity that have influenced Republican tax reform advocacy for decades.

42. Grover Norquist

The founder and President of Americans for Tax Reform and creator of the Taxpayer Protection Pledge, Grover Norquist has been the most influential anti-tax activist in the United States for four decades. The Pledge, which commits signatories never to vote for a net tax increase, has been signed by hundreds of Republican officeholders and has functioned as one of the most durable constraints on US federal tax policy since the Reagan era. His advocacy directly shaped the parameters within which the OBBBA was designed, ensuring that the package was structured to avoid net tax increases on a static-scoring basis.

Norquist's contribution to the US tax strategy landscape is structural rather than technical: he defines the political constraints within which tax legislation must operate on the Republican side of the aisle, and understanding those constraints is essential for anyone working on or around the US tax policy process. His Americans for Tax Reform organisation also produces analysis of specific tax proposals through a consistent anti-tax lens that provides useful information about the political pressure points that shape tax law.

43. Martin Sullivan

Recently retired in April 2026 as Chief Economist and Contributing Editor of Tax Analysts after a career that began at Tax Notes nearly 45 years ago, Martin Sullivan is one of the most important economists in the history of US tax journalism. His more than 1,000 economic analyses for Tax Notes, two books on tax reform, and congressional testimony represent a career-long commitment to making the economics of tax policy legible for practitioners, academics, and policymakers. He was awarded the National Tax Association's 2021 Davie-Davis Public Service Award and the 2019 Tax Council Policy Institute Pillar of Excellence Award.

Sullivan's analysis of how the world's largest corporations avoided taxes through 'stateless income' structures, documented in a Washington Post profile by Pulitzer Prize-winning journalist Steven Pearlstein, anticipated many of the structural reforms that eventually became the GILTI and Pillar Two frameworks. His career reflects the rare combination of technical depth, journalistic clarity, and genuine independence that the public tax conversation needs but rarely gets. His retirement marks the end of a specific kind of institutional intellectual leadership at Tax Notes.

44. Brian Galle

A Professor of Law at UC Berkeley School of Law, where he joined the faculty in 2025 after a decade at Georgetown Law, Brian Galle teaches and researches federal income taxation, nonprofit organisations, and the behavioural impacts of tax policy. In 2026, he co-drafted the California Billionaires Tax Act initiative alongside Emmanuel Saez, David Gamage, and Darien Shanske, which would impose a one-time wealth tax on California billionaires to fund healthcare following federal Medicaid cuts. His research, which frequently tests conventional wisdom about tax incentives and the allocation of public resources, makes him one of the more distinctive academic voices on the reform end of the US tax conversation.

Galle's contribution is in using academic tax law research to directly inform and design legislative proposals rather than only commenting on them. His move from Georgetown to Berkeley in 2025, combined with his active participation in the California wealth tax initiative, positions him as a voice that bridges the academic and advocacy worlds in a way that is unusual for a law school professor. His ability to translate complex tax law design questions into implementable policy proposals reflects both his technical depth and his commitment to making research consequential.

Category 8: Digital, Technology, and Emerging Tax Voices

The professionals in this category are navigating the frontier where new technology, new asset classes, and new administrative tools are rewriting the rules of US tax strategy in real time.

45. Tom Shea

As EY's Americas Crypto and Digital Asset Tax Leader, Tom Shea is one of the most prominent practitioners working specifically on the tax treatment of digital assets in the United States. His June 2026 commentary on the separate treatment of the crypto tax bill and broader market-structure legislation in Congress, which clarified that the IRS and Treasury view the tax treatment of digital assets as a distinct legislative matter, has been widely cited by digital asset practitioners. His analysis of Form 1099-DA broker reporting requirements, which came into effect in 2025, provided essential guidance for the crypto practitioner community during the first full year of implementation.

The digital asset tax space is one where the gap between the rate at which new asset types, transaction structures, and platforms are being created and the rate at which the IRS is producing guidance has created genuine planning uncertainty for practitioners and their clients. Shea's work at EY, where he advises both institutional investors and operating businesses on their digital asset tax obligations, makes him one of the more practically grounded voices on a topic that is often discussed in purely theoretical terms.

46. Shehan Chandrasekera

Head of Tax Strategy at CoinTracker and one of the few CPAs in the country recognised as a subject matter expert on cryptocurrency taxation, Shehan Chandrasekera was among the first practitioners to publicly welcome the IRS's 2024 and 2025 digital asset guidance, noting that having published guidance, even imperfect published guidance, is a significant step forward for compliance. His work at CoinTracker, which served as the basis for the April 2026 joint Crypto Tax Readiness Report with Coinbase surveying 3,000 US crypto investors, gives him direct visibility into the practical compliance challenges created by high-volume digital asset activity.

Chandrasekera's contribution is in occupying the space between the technical regulatory landscape and the practical experience of clients who hold digital assets. His analysis of the 2026 Crypto Tax Readiness Report, which found that 74% of crypto users know their activity is taxable but only 49% correctly understand when a taxable event is triggered, provided one of the most rigorous data-backed pictures of the compliance knowledge gap that tax professionals need to address.

47. Chris D'Ambola

As Managing Director of BDO's Tax Automation and Innovation Practice and host of the Tax at the Speed of Tech podcast, Chris D'Ambola is one of the most publicly visible practitioners working at the intersection of tax technology, artificial intelligence, and the transformation of the corporate tax function. His podcast features conversations with tax, technology, and BDO leaders focused on reimagining the tax function to be more efficient, analytical, and strategic. His coverage of how AI tools are beginning to automate routine compliance tasks and augment practitioner judgement in complex planning decisions reflects direct experience with how the transformation of the tax function is actually happening in practice.

D'Ambola's contribution is in making the practical reality of tax technology transformation accessible to corporate tax professionals who are aware that AI and automation are reshaping their function but need grounded, practitioner-tested guidance rather than theoretical frameworks. His BDO platform gives him the scale and client access to observe transformation across a genuinely diverse cross-section of the corporate tax market.

48. Caroline Weber

Co-editor of the National Tax Journal, the flagship peer-reviewed journal of the National Tax Association, and a Professor of Economics at the University of Kentucky, Caroline Weber was appointed in 2023 alongside Andrew Samwick to lead one of the most important platforms for empirical tax research in the United States. The National Tax Journal, published since 1948 and now published by the University of Chicago Press, provides the primary academic platform for the rigorous empirical and theoretical work that eventually shapes US tax policy and practice.

Weber's role as co-editor positions her as a gatekeeper and amplifier of the research that matters most in academic tax economics. Her ability to identify and develop work that is both technically rigorous and policy-relevant, across the full spectrum of topics the Journal covers, makes her institutional contribution as important as her individual research output.

49. Joseph Thorndike

A contributing editor at Tax Notes and the Director of the Tax History Project, Joseph Thorndike brings a historian's perspective to the US tax policy conversation that is rare and genuinely valuable. His work documenting the history of US tax policy, from the income tax's origins to its successive reforms, provides the long-run context that is often missing from contemporary tax debates. His contributions to the Tax Notes Talk podcast and his commentary on the historical precedents for the OBBBA's permanent TCJA extension connect current policy disputes to their historical antecedents in ways that illuminate both the policy arguments and the political dynamics.

Thorndike's historical perspective is particularly useful in the current environment, where major tax legislation is often framed as unprecedented when in fact it reflects recurring patterns in the American tax policy cycle. His ability to situate the OBBBA's distributional choices, the debate about the estate tax exemption, and the arguments around corporate tax reform within a historical framework that spans more than a century of US tax history makes his contribution genuinely additive to the contemporary policy conversation.

50. Michelle Nessa

An Associate Professor in the Department of Accounting and Information Systems at Michigan State University, Michelle Nessa researches the effects of taxes on business decisions, with a particular focus on R&D tax policy, the taxation of multinational companies, and corporate tax planning. Her 2025 research, co-authored with colleagues, documented that companies were forced to defer more than $59 billion in tax benefits under the revised Section 174 R&D capitalisation rules, with the most R&D-intensive companies in their sample cutting R&D investment by 11.6% in the first year of the new regime. Her work provides rigorous empirical evidence for one of the most contested questions in US corporate tax policy: how do tax incentives actually affect investment and innovation decisions?

Nessa's research sits at the intersection of accounting, economics, and corporate finance in a way that is genuinely cross-disciplinary and policy-relevant. Her findings on the research credit, bonus depreciation, and the interaction between tax policy and corporate investment decisions have direct implications for how practitioners and policymakers assess the effectiveness of corporate tax incentives. Her continued research engagement in 2025 and 2026 reflects a faculty career oriented toward producing work that matters beyond the academic literature.

Notable Voices We Almost Included

A few voices deserve acknowledgment even though they did not make the final 50. Gabriel Zucman, the co-creator with Emmanuel Saez of the wealth inequality measurement methodology, is based at UC Berkeley but whose most prominent recent work has been shaped from a global platform rather than a specifically US-focused practice. The editorial team at Tax Notes as a whole represents a collective intellectual contribution to US tax journalism that goes well beyond any individual contributor's work. Andrew Samwick at Dartmouth, who co-edits the National Tax Journal alongside Caroline Weber, brings a macroeconomist's perspective to fiscal policy research that complements the tax-specific expertise of many others on the list.

Common Mistakes to Avoid in US Tax Strategy

The most common mistake organisations make in US tax strategy is treating it as a compliance exercise rather than a planning opportunity. The US tax code is one of the most extensively incentive-laden in the world. From bonus depreciation and the qualified business income deduction to R&D credits and opportunity zone investments, the code is filled with provisions designed to reward specific types of investment and business behaviour. Business owners and CFOs who engage with their tax function only at year-end, when decisions have already been made and the planning window has largely closed, routinely leave significant value on the table.

A closely related error is failing to integrate tax planning with broader business strategy. The choice of entity structure, the timing of asset purchases, the design of executive compensation, the structure of cross-border operations, and the approach to M&A transactions all have substantial tax implications that can be managed if they are considered early in the decision-making process but that become difficult or impossible to address after the fact. The practitioners on this list who serve business owners consistently emphasise that the highest-value tax planning conversations happen before decisions are made, not after.

The third common mistake is failing to distinguish between different types of uncertainty in the tax environment. Some things are knowable and plannable. The OBBBA's permanent extension of most TCJA provisions means that the individual income tax rate structure, the qualified business income deduction, and the estate tax exemption are now predictable for planning purposes. Other things, including the outcome of Pillar Two negotiations, state conformity decisions, and IRS enforcement priorities under a changing administration, are genuinely uncertain. Effective tax strategy differentiates between these categories rather than treating all tax uncertainty as equivalent.

A fourth mistake is treating digital assets and emerging compensation structures as tax-planning edge cases rather than mainstream planning considerations. The implementation of Form 1099-DA broker reporting in 2025, the continued growth of equity compensation in private and public companies, and the rapid evolution of cryptocurrency transaction volumes mean that any business or individual with exposure to these areas needs a specific, current strategy, not a generic assumption that existing planning frameworks apply.

Implementation Guide: How to Build Your US Tax Strategy Information Diet

The most effective approach to staying informed on US tax strategy in 2026 is to build a curated information diet that covers all four layers of the tax knowledge stack: policy design, legislative interpretation, practitioner guidance, and compliance requirements.

For the policy layer, the Tax Foundation's Daily Tax Report and ITEP's research publications provide the analytical infrastructure for understanding how proposed and enacted legislation actually works and who it affects. Following Erica York and Garrett Watson on LinkedIn gives direct access to the most technically current analysis of federal and state tax developments from a non-partisan research perspective. The Urban-Brookings Tax Policy Center's TaxVox blog provides an equally valuable analytical perspective with greater emphasis on distributional effects.

For the legislative and regulatory interpretation layer, Tax Notes, particularly through David Stewart's Tax Notes Talk podcast, provides real-time expert interpretation of regulatory guidance and legislative developments. Richard Rubin's Wall Street Journal coverage provides the most widely-read mainstream journalistic account of what is happening in the tax world. Subscribing to the Grant Thornton and BDO Tax Alerts newsletters provides firm-level interpretation of how specific provisions apply in practice.

For the practitioner guidance layer, the Small Business Tax Savings Podcast with Mike Jesowshek and Tom Wheelwright's WealthAbility Show cover the small business and entrepreneurial perspective with genuine technical depth. For larger organisations, the PwC Cross-Border Tax Talks podcast with Doug McHoney and Pat Brown provides some of the most technically current guidance on international tax strategy available for free.

For the compliance requirements layer, Annette Nellen's 21st Century Taxation blog provides comprehensive, timely coverage of state and local tax developments and emerging compliance issues, including digital assets, worker classification, and the interaction between federal and state tax rules.

For organisations that need a structured approach to communicating about tax strategy internally, Jonno White's work with executive teams on communication, alignment, and decision-making frameworks is directly relevant to how leadership teams process and act on the intelligence that the voices in this directory provide.

Frequently Asked Questions

Who are the top tax thought leaders in the USA right now?

The most influential voices in US tax strategy in 2026 span multiple disciplines. For policy analysis, Erica York and Kyle Pomerleau at the Tax Foundation and AEI, and Len Burman and Howard Gleckman at the Tax Policy Center, are the most technically rigorous publicly accessible voices. For academic research, Joel Slemrod, Raj Chetty, and Emmanuel Saez produce the evidence that shapes legislative debates. For practitioner guidance, Tom Wheelwright, Mike Jesowshek, and Jackie Meyer lead on small business strategy, while Doug McHoney and Pat Brown at PwC lead on international strategy. For journalism, Richard Rubin at The Wall Street Journal and Lee Sheppard at Tax Notes are essential follows.

What does a US tax strategy thought leader actually do?

A US tax strategy thought leader engages with the public conversation about how tax law works, what it should look like, and how businesses and individuals can navigate it effectively. This includes publishing research, writing articles and books, contributing to policy debates, speaking at conferences, hosting podcasts, and maintaining a public professional presence that educates practitioners, policymakers, and taxpayers. The people on this list have demonstrated a consistent commitment to this kind of public engagement rather than confining their expertise to client-only channels.

What is the most important US tax strategy issue in 2026?

The single most important issue for most US business owners and tax professionals in 2026 is understanding the full implications of the One Big Beautiful Bill Act, enacted in July 2025, which permanently extended most TCJA provisions, raised the estate tax exemption, and reshaped international tax rules. According to the 2026 BDO Tax Strategist Survey, 30% of senior tax leaders cite regulatory complexity as their greatest enterprise tax risk, more than double the prior year. For business owners, the immediate planning priorities include reassessing entity structure, optimising bonus depreciation claims, and reviewing estate plans in light of the elevated exemption levels.

How do I find the best tax strategy resources in the USA?

The best free resources for following US tax strategy include the Tax Foundation's analysis at taxfoundation.org, the Tax Policy Center's TaxVox blog, the Tax Notes Talk podcast, the Small Business Tax Savings Podcast by Mike Jesowshek, the WealthAbility Show by Tom Wheelwright, and Richard Rubin's Wall Street Journal coverage.

Final Thoughts

The US tax landscape in 2026 is more technically complex and more politically consequential than at any point in the past generation. The permanent extension of TCJA provisions, the rebranding of international tax rules under the OBBBA, the first full year of digital asset broker reporting, and the ongoing tension between US tax policy and the OECD's Pillar Two framework all create a planning environment where the quality of your information sources directly affects the quality of your decisions.

The 50 voices in this directory represent the full spectrum of how the US tax strategy conversation gets made and communicated, from the economists designing the policy frameworks to the journalists translating them, from the academics testing assumptions to the practitioners showing business owners how to act on what the code allows. Following a curated set of these voices, tuned to the specific part of the tax landscape most relevant to your organisation, is one of the highest-leverage investments any financial leader can make in 2026.

For leadership teams that need help translating what they are reading and hearing from these voices into internal action, Jonno White offers executive facilitation, team alignment workshops, and leadership coaching designed specifically for the communication and accountability challenges that complex information environments create. Email jonno@consultclarity.org or visit consultclarity.org to learn more. International travel is often far more affordable than clients expect, and virtual facilitation is always available.

The US tax strategy landscape sits within a broader global conversation about how tax systems are being redesigned and contested. For the voices shaping that global conversation, including OECD architects of Pillar Two, in-house tax leaders at multinational corporations, and the economists who built the wealth inequality measurement framework that is driving billionaire tax debates around the world, read the blog post '50 Essential Global Thought Leaders on Tax Strategy.'

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.
