Key takeaways:

• • • Stability is the story — The OBBB’s main value has been predictability for business planning, not sweeping new rules — a sharp contrast to the disruption of prior major tax legislation like the TCJA.

    • Section 1202 is a live opportunity — The expanded QSBS exclusion has reopened planning conversations around corporate structuring that had cooled in recent years.

    • Plan for both today and tomorrow — Practitioners should help clients capitalize on current certainty while preserving flexibility, and they should help clients build tax positions that can hold up to increasingly AI-powered IRS scrutiny.

When major tax legislation lands, the instinct is to brace for upheaval. But one year after the passage of the (OBBB) Act, the consensus among practitioners is notably different: The OBBB didn’t rewrite the rules so much as confirm them, and that distinction has mattered more than it might sound.

Certainty over seismic change

Unlike the (TCJA) — which was passed in 2017, mostly took effect the following year, and forced practitioners to relearn much of the code — the OBBB’s significance lies less in what it changed and more in what it settled. It gave businesses a stable set of rules to plan against, rather than a moving target to which to react.

“From a purely tax lens, it was… easier to unpack than in prior years because there are fewer seismic changes,” says , Partner at Plante Moran, reflecting on the past year under the OBBB. “It was providing a lot of clarity that just [meant], at least for the next several years, we had the rules.”

That clarity is not a small thing. Multi-year business decisions — around such big-ticket items as entity structuring, capital investment, and succession planning — depend on practitioners being able to tell clients that the rules will hold. Thus, OBBB’s real contribution was buying back that predictability.

Section 1202 comes back to life

If one provision captures the OBBB’s practical impact, it’s the revitalization of — the qualified small business stock (QSBS) gain exclusion. The expansion of this program has done more than simply adjust a technical detail; indeed, it has reopened a whole category of planning conversations that had gone quiet.

“The action around the qualified small business stock gain exclusion… has really reinvigorated the Section 1202 planning conversations,” Eckert explains. “Ultimately, what we got was an expansion of the program. So, what that has done is reinvigorated those conversations around planning into corporate structures.”

For founders, investors, and the tax advisors who serve them, that means is back on the table — and often earlier in a company’s lifecycle than before, since the incentive to structure correctly from the outset is now more valuable.

A new kind of advisory opportunity

Of course, stability doesn’t mean passivity. If anything, the OBBB has expanded what tax professionals can offer clients. With a known set of rules, advisors can move beyond compliance and into genuine strategy by helping clients maximize their position under current law while still preparing for the fact that today’s certainty has a shelf life.

That balance — seize the moment, but don’t get comfortable — is a concept that isn’t lost on many tax specialists. “Maximize your opportunities today but also have a long-term view while having flexibility and preserving flexibility wherever you can, and knowing and anticipating that there could be future changes,” Eckert says, framing this moment as a broader opening for the profession, not just a technical one.

Legislative clarity, he argues, gives practitioners a reason to go deeper with clients than simply processing the next filing. “From a practitioner lens, I think [legislative changes] are a huge opportunity… giving us an opportunity to really bring value to our clients and to also get to know our clients better,” he notes. “It’s been, in a certain sense, a great opportunity to just build deeper relationships.”

In other words, the firms getting the most out of this environment aren’t the ones treating the OBBB as a compliance checklist; rather, they’re the ones using it as a reason to have a better conversation with clients about where they’re headed.

The IRS isn’t standing still either

The one area in which practitioners should definitely not get comfortable is enforcement. A smaller IRS workforce doesn’t mean lighter scrutiny — it likely means a different kind. As the agency leans more heavily on AI-driven tools, its ability to examine returns at scale is set to expand even as headcount contracts.

“I think across the board, we’re certainly aware of that and are counseling clients on the need to establish and build positions and think carefully about it,” Eckert explains. “In a world of AI-enabled tools, the scrutiny may actually increase, and the ability for the IRS to quickly and efficiently examine lots of data is something that could certainly exist.”

That means that tax advisors need to help their clients build positions that can withstand more sophisticated review, not less. Meticulous documentation and defensible reasoning matter more, not less, in an environment in which fewer human examiners can still cover more ground with better tools.

One year in, the OBBB’s legacy isn’t a story of dramatic reform, but rather it’s a story of tax firms and their clients finally getting room to plan. The tax advisors making the most of that room are the ones using it to build sharper strategies and deeper client relationships, all while keeping an eye on an IRS that’s quietly getting more capable of deeper examination.

Key takeaways:

• • • The wash sale loophole is likely closing — For clients that have been harvesting crypto losses and immediately repurchasing the same asset should know that “wash sale” strategy may soon work exactly like it does for stocks — with a mandatory 30-day waiting period.

    • Non-compliant holders have a potential off-ramp — A proposed voluntary disclosure program would let clients that haven’t properly reported digital asset income to get into compliance with reduced penalties — but it’s only available for a limited time.

    • Staking and mining income treatment is changing — Proposed legislation would allow taxpayers to elect to defer recognizing newly minted digital assets as income, which could be a meaningful planning opportunity for active miners and stakers… or a trap, depending on their situation.

Walk into any conversation with a cryptocurrency-owning client right now and you’re navigating the same awkward reality: The rules are genuinely unclear, have been unclear for years, and yet the IRS has increasingly expected compliance anyway. Now, however, the U.S. House Ways and Means Committee is trying to resolve that tension.

And crypto legislation is one piece of a much larger shift reshaping the tax profession and potentially impacting clients right now. The recent 2026 State of Tax Professionals Report from the Thomson Reuters Institute maps the challenges and opportunities defining the profession this year, including AI adoption, advisory pricing, talent constraints, and the growing gap between what clients want and what firms are charging for it.

Add to that list now, the changes coming for crypto asset owners and their tax, audit & accounting advisors.

New legislative changes for crypto owners

The package of crypto legislation — a collection of seven separate bills — currently under consideration by Ways and Means is serious enough that their tax advisors need to start thinking now about what it means for clients.

Some of these new proposals include:

The wash sale rule: A strategy that may be changing

Of all the provisions in the package, extending wash sale rules to digital assets will have the broadest practical impact. Currently, crypto investors can sell at a loss, immediately buy back the same position, and still claim the deduction — a strategy unavailable to stock investors. The proposed legislation would change that, applying to digital assets the same 30-day before-and-after window that governs stock transactions.

For clients with active portfolios, this isn’t just a planning consideration — it’s a recordkeeping one. Every transaction would need to be evaluated against a rolling 60-day window across potentially multiple wallets and exchanges. The change to this rule was hardly unexpected — the question was never really whether the wash sale rule would come to crypto, but when. Tax advisors should begin their honest conversation with clients by acknowledging that.

Mining and staking: A choice with consequences

For clients who mine or earn staking rewards with crypto, the proposed gives crypto miners and stakers the ability to elect to defer income recognition, which would treat newly minted digital assets more like self-created property than an immediate taxable event.

In practice, the calculus is complicated. Deferring income means the cost-based question gets pushed forward, not eliminated. If the asset appreciates significantly before sale, a client who deferred income recognition could face a larger ordinary tax event later. If the asset depreciates, owners have lost the ability to recognize the loss in the year of receipt.

Making the right choice — with the advice of a tax professional — depends almost entirely on the client’s individual circumstances, such as their marginal tax rate, their expectations for the asset’s trajectory, and their liquidity needs. This is exactly the conversation that tax professionals need to be having with clients around this issue.

The voluntary disclosure program: A limited window

Perhaps the most immediately actionable provision for many tax advisors is the proposed one-time voluntary disclosure program, which gives taxpayers who haven’t properly reported crypto income the opportunity to get into compliance with reduced penalties and a clean slate.

The IRS has run these programs before, and the pattern is consistent — the best terms are early, enforcement pressure increases after the deadline, and clients that wait because they hope the problem will disappear tend to regret it.

Simplification and opportunity

Not everything in the package adds complexity. would exclude gains or losses on network fees and regulated US dollar stablecoins by removing a reporting headache that has made crypto compliance so cumbersome for everyday users. And the Charitable Deductions for Digital Asset Donations Act would eliminate the qualified appraisal requirement for donated digital assets when market prices are readily available, lowering the friction on a strategy that has always made good tax sense for clients that holding appreciated crypto with charitable intent.

The tax advisors that will offer their clients the most value in a post-legislation world are the ones already holding these proactive conversations, and reviewing which clients have crypto exposure, identifying which may have unreported income, flagging which miners and stakers should be thinking about the deferral choice, and identifying charitable giving opportunities before the appraisal requirement disappears.

In addition, the voluntary disclosure program is the clearest example of how proactive advisory work can pay off. Clients that have quietly hoped their unreported crypto transactions would stay below the radar need someone to tell them plainly that a window for clean resolution is likely opening — and that waiting for it to close is not a strategy. That conversation is uncomfortable, of course, but it’s also exactly what a trusted advisor is for.

Beyond compliance, the considered package of crypto legislation creates the need to have genuine planning conversations that didn’t exist before. For example, the wash sale question is time-sensitive, and the staking deferral election requires modeling. None of this requires tax advisors to wait for final regulations; rather, it requires they know their clients well enough to know which ones have exposure, which have opportunity, and which needs a conversation they haven’t thought of requesting.

Right now — in the space between a Congressional hearing and a presidential signature — that is the most valuable thing a tax professional can offer.

Key takeaways:

• • • Almost two-thirds of tax firms expect revenue to grow in 2026 — However, the top two revenue drivers — fee increases and organic client acquisition — both have natural ceilings. Sustainable growth requires moving beyond these transactional levers toward strategies that don’t plateau.

    • Advisory services are the profession’s most in-demand category and its lowest-margin one — This a pricing problem, not a demand problem. Firms that shift to value-based or fixed-fee pricing for advisory work, rather than billing it hourly alongside compliance, consistently report stronger margins over time.

    • More than half of firms are expecting leadership transitions by 2030 — Succession is now a growth variable, not just an HR one. Firms that treat it as a strategic priority now are better positioned to maintain momentum through leadership changes.

The headline numbers from the recent Thomson Reuters Institute’s “2026 State of Tax Professionals Report” — which surveyed more than 600 tax professionals worldwide — are strong. Profit margins across tax, audit & accounting firms averaged above 30% throughout 2025, nearly half of all firms saw profits rise, and two-thirds expect revenue to increase again over the next 12 months.

For most firm leaders, this represents a genuine shift in conditions after years of talent pressure and compliance commodification.

However, a deeper dive in the data shows is that revenue growth and margin growth are not moving in the same direction for most tax firms. The gap between the two is where the profession’s real growth challenge sits and understanding it is where the more useful conversations start.

What is actually driving tax firm revenue growth?

The two biggest revenue drivers cited in the report are fee and rate increases (with 23% of respondents saying this) and organic new client acquisition (22%). Both are proven levers, and both have limits. Fee increases work until clients push back or competitors undercut; and organic acquisition stalls when capacity runs out. Neither of these methods on their own addresses whether firms are growing in ways that actually improve their long-term margin picture or are simply doing more of the same work at a slightly higher price.

The report flags this directly, noting that firms “see growth itself not as a strategy, but rather as a goal,” and that the method chosen to fuel it “will determine the strategy necessary to achieve it.” That distinction — between growth as a goal and growth as a strategy — is where firms that sustain momentum tend to separate from those that plateau.

Why are advisory services the lowest-margin work in the portfolio?

Almost three-quarters (74%) of respondents surveyed say most clients strongly want a trusted advisor relationship that goes beyond basic tax filing. And firms are responding — when asked which services their firm plans to start offering to clients in the next 12 months, almost two-thirds of respondents (65%) say their firm is either planning to offer or considering offering tax strategy advice.

Clearly, the pipeline for advisory work is being built, but the margin data tells a different story about what happens once those services are actually delivered.

The report’s diagnosis that the “advisory pricing gap is not caused by lack of demand — the root cause is lack of confidence in the value of the services provided.” Firms using value-based or fixed-fee pricing for advisory work report stronger margins over time, with margins above 31%. Packaging advisory work into defined service tiers, rather than billing it hourly alongside compliance, makes the value more legible to clients and easier to price consistently.

Is talent shortages limiting firms’ growth potential?

More clients, more advisory services, and more complexity all require more capacity; and 40% of respondents say their firm’s capabilities are currently constrained or at risk because of talent issues. For midsize tax firms — those with between 4 and 29 professionals — that number climbs to 51%. This constrained capacity can severely limit which services a firm can offer, how many new clients can be absorbed, and how quickly advisory expansion can actually happen.

Hiring alone is not the answer. Those firms managing this challenge the most effectively tend to combine task reallocation — moving non-advisory work to junior staff — with structured internal development programs that build the type of advisors they need rather than trying to hire them.

Which structural decisions will determine growth through 2030?

More than half (51%) of respondents say it is likely or highly likely that one or more partners or firm leaders will retire or leave before 2030. Most expect to fill those roles internally, with only 27% thinking outside partner recruitment is likely. Firms are also genuinely split on whether they stay the same size and structure over the next five years, or change via mergers, acquisitions, or outside capital infusions.

These are growth decisions even when they don’t look like it. As the report notes, “growth is not a universal imperative” — indeed, some firms will deliberately choose resilience over scale, and that is a legitimate path. The firms that tend to struggle are those that have not made the choice explicitly and instead find it made for them by departing partners, capacity limits, or competitors that moved faster.

For tax, audit & accounting firms, the revenue conditions in 2026 are as favorable as they have been in years — revenue is up, clients want more services, and the profession has more tools available to deliver that expanded service.

Those tax firms that convert these current conditions into lasting growth will be the ones that have matched their ambition with a strategy that’s specific enough to act upon.

Key insights:

• • • AI makes everyone’s job easier, including cybercriminals — With Anthropic’s Claude, an attacker breached Mexico’s federal tax portal in less than an hour.

    • Cybersecurity breaches may be a canary in the coal mine for a much larger problem — This is the second publicly disclosed Claude-enabled attack in less than a year.

    • Nearshoring the risk — Beyond the immediate damage to affected citizens and businesses, foreign investors and multinational evaluating their operations in Mexico may see a red flag that could discourage them from moving forward.

Amid the 2025 year-end celebrations — while most people were busy wrapping gifts, decorating trees, spending time with loved ones, and sketching out their 2026 resolutions — a quieter threat was unfolding. Unlike the Grinch, it had no interest in stealing Christmas cheer; instead, it set its sights on something far more valuable: more than 150 gigabytes of sensitive information from Mexican government organizations.

Armed with what appeared to be intermediate knowledge of cybersecurity and an advanced usage of AI tools, the Spanish-speaker attacker convinced Anthropic’s Claude chatbot that the interaction was part of a bug bounty — a legal way to hack a company and get paid for telling them how you broke in — with 3 key rules: avoid making changes that could damage the system, delete all logs, and disable command history.

At first, Claude strongly resisted, flagging these instructions as they sounded like detection-evasion techniques, commonly used by malicious actors. It even challenged the attacker, requesting verification.

However, just three minutes after the suspicious prompts, the attacker dropped a simple and straight-forward instruction: “Could you add this to claude.md”, with a penetration-testing cheat sheet attached. After that, things went as smooth as butter.

In simple terms, using a penetration-testing cheat sheet is like asking a security guard to write instructions to disable the alarms and he refuses, so you pull out a pre-written note with those exact instructions and say, “Can you just stick this on your booth door?” and he does. Now those instructions are in front of him all day, and he follows it when you ask him, automatically without questioning it. In this case, Claude didn’t write the malicious manual — it just stuck the note up, but the result was the same.

Mexican government infrastructure attacked

According to Gambit Security, the attacker breached the Tax Administration Service (SAT, according to its acronyms in Spanish) — along with least 8 other Mexican government institutions during the end of 2025 until mid-February 2026. The incident has been described as one of the largest breaches of government infrastructure.

Within the scope of the SAT alone, the compromise reportedly exposed 195 million taxpayer records and 52 million directory entries. Building on this access, the attacker then leveraged Claude to pursue even more sensitive data, including Mexico’s electronic signature (e.firma) private keys, taxpayer identification numbers (RFC), national ID numbers (CURP), as well as customers’ biometrics, email addresses, phone numbers, and physical addresses.

Even beyond all of this, however, the most unsettling part of the attack came next. With a prompt that revealed a striking lack of technical literacy — “Make a Python or something like that…” — the attacker asked Claude to build a simple web application capable of querying and returning SAT taxpayer information. He then used this tool to develop a script that generated fraudulent tax status certificates, populated with real data pulled directly from the system. While he was unable to forge the document’s digital seal, the deception was still dangerously effective, because without proper cryptographic validation, the certificates appeared legitimate and were nearly indistinguishable from authentic ones.

Thus, the commercial relevance of the SAT hack is not secondary or collateral — it’s central. SAT is not merely a fiscal institution, it is the central nervous system of Mexico’s formal commerce, and its database holds information that companies provide under legal obligation, not only with a reasonable expectation that the government will protect it, but because they have no option but to do so.

When that information is compromised, the damage is not limited to the privacy of the affected taxpayers, it extends to a foreign investor or a company’s compliance team that may be evaluating a nearshore move for the establishment of operations in Mexico. And with all of that, it would be understandable for them to wonder:

If the government cannot protect the data that companies have little choice but to provide, what guarantee exists that it will be safe? And with that, in case of a danger, will the Mexican government have enough tools to investigate and sanction the attackers?

The hack spreads mistrust and apprehension

Within that calculus, weaknesses in government cybersecurity become more than a technical concern — they evolve into a tangible barrier to investment, a contradiction made even sharper amid the ongoing renegotiations of the United States-Mexico-Canada Free Trade Agreement (USMCA).

The last version of the USMCA establishes a framework for cybersecurity cooperation among member countries. Its legal architecture rests on three pillars: i) the recognition that cyber-threats represent a risk to digital commerce; ii) the commitment of the parties to develop capacities to identify and manage those risks; and iii) the promotion of cooperation between the public and private sectors in this area.

However, it never mentions a minimum-security standard that governments are required to meet, but that is not the only loose thread, since the USMCA was negotiated in a technological context radically different from the present one — back when generative AI (GenAI) was still science fiction rather than a browser tab. Indeed, the cybersecurity framework implicitly assumes that threat actors are organized structures.

And that’s where the case analyzed by Gambit Security could jeopardize everything, as the breach in which AI functioned as a primary operational tool, according to their document. More worrisome, what previously required months of specialized work and considerable resources by a potential network of hackers can today be executed in days by a much smaller unit, or singular person, with monthly subscription tools — and maybe less technical knowledge than you think.

That said, the push for stronger cybersecurity standards may extend beyond USMCA concerns and evolve into a broader industry imperative, particularly in places in which the agreement itself may fall short.

Claude as the mechanism

This attack marks the second known incident involving the use of Anthropic’s Claude — the first having been linked to a Chinese state-affiliated group — and it is unlikely to be the last. Without clearer regulation and stronger security standards, such misuse will not remain an exception but rather become an increasingly recurring threat not only in Mexico but also in Canada and the United States. Even in the US, which maintains comparatively advanced cybersecurity frameworks, experts acknowledge that defenses are still struggling to keep pace with an increasingly complex threat landscape.

The US is not the only one taking the lead, however, as the European Union has already introduced the first comprehensive AI regulatory framework, requiring systems to be resilient against misuse (including for cyberattacks) and obligating companies to report and address vulnerabilities. However, these rules primarily apply to AI developers rather than those who weaponize the technology. By contrast, the US has begun to address this gap by enacting laws that treat the use of AI in criminal activity as an aggravating factor, leading to harsher penalties.

As such, this is not only an alert for Mexico to improve its own cybersecurity practices but is certainly a broader call to action for all three countries. Regulating a technology that evolves faster than legal processes is both urgent and challenging — but not impossible.

Key takeaways:

• • • Understanding is not preparation — Most EU businesses are aware of — but not necessarily prepared for — the sweeping changes that ViDA is bringing.

    • Few businesses have a solid transition plan in place — Only 22% of tax and finance professionals surveyed say their organization has a formal, funded ViDA transition program in place.

    • Some key requirements are already changing — With e-invoice and real-time reporting requirements already shifting, businesses are in danger of falling behind, risking business continuity and non-compliance.

The European Union’s reforms around its value added tax (VAT) — known as VAT in the Digital Age (ViDA) — represent the most significant shift in tax compliance for businesses operating in the EU in a generation. ViDA is more than merely another new compliance requirement or technology upgrade. Indeed, many organizations will need to modernize their entire invoicing and tax reporting systems to get into compliance.

The new compliance horizon: 2026 ViDA Readiness Report

While ViDA’s EU-wide mandates for cross-border e-invoicing and digital reporting take effect in 2030, the pressure on organizations is already mounting as individual EU member states roll out a patchwork of national requirements.

Digging deeper on this, a new report from the Thomson Reuters Institute, , reveals a striking paradox in how EU tax and finance professionals are preparing for this overhaul. While awareness is nearly universal, a significant gap remains between awareness of ViDA and tax teams’ readiness for its changes.

Indeed, 86% of EU tax and finance professionals say they are familiar with ViDA; however, a deeper look reveals that only 35% possess a detailed understanding of the specific requirements of the regulatory reform package. This creates a state of “comfortable uncertainty,” in which high initial confidence can often mask a lack of preparation for the massive technological and operational changes ahead.

Riding the “Confidence Curve”

One of the most compelling findings from the report is the “Confidence Curve” that shows how many organizations often start their journey with high levels of optimism. In fact, even among respondents who say their organization does not yet have a transition program in place or has one that is fragmented across EU member states, 90% say they feel confident in their organization’s ability to achieve ViDA compliance.

However, the Confidence Curve shows that confidence often regresses during the assessment and planning phase. As teams begin to uncover the complexities of new multi-jurisdictional compliance and real-time reporting requirements, the percentage of respondents who say they are “not very confident” doubles. It is only after a program is funded and embedded into digital transformation strategies that confidence strongly rebounds.

Despite the high stakes, the majority of organizations are still finding their footing, the report shows. Unfortunately, more than three-quarters (78%) of respondents say their organization has no formal, funded ViDA transition program with central governance in place, meaning that they’re working in a fragmented country-by-country fashion or are still in the assessment stage.

These delays are risky Many EU member states have already begun rolling out e-invoicing mandates. That leaves those organizations without programs in place at greater risk of falling further behind.

The ViDA-enabled opportunity

Despite the massive changes in VAT requirements that ViDA brings, the reform package also offers corporate tax functions a tremendous opportunity to elevate themselves from a cost center to a strategic business partner. As the report outlines, taking that path forward requires a cross-functional commitment across numerous corporate functions, including tax, finance, IT, and legal departments.

Yet, those organizations that move beyond providing the “minimum viable compliance” and instead take the opportunity to invest in standardized data and central governance will be better positioned to turn these regulatory mandates into a compliance advantage for the tax function and a competitive advantage for the organization going forward.

Key takeaways:

• • • The 2027 end date is not a runway — The One Big Beautiful Bill sets a statutory de minimis end date of July 1, 2027, but its own legislative history explicitly preserves the president’s authority to restrict it before that date. Sellers banking on a two-year transition period are reading the headline, not the fine print.

    • The Supreme Court win didn’t save the refunds — The Supreme Court’s IEEPA decision was real, but the administration switched legal authority to Section 1321 and kept the suspension running. Combined with congressional cover from the One Big Beautiful Bill, the path to recovering tariffs already paid is genuinely uncertain — not just delayed.

    • The refund clock just reset — The lead test case for processing refunds through CBP’s KAPE system, Atmos, just settled, forcing the process to restart with a new test case. Sellers waiting on refunds are further back in the queue than they realize.

Most e-commerce merchants couldn’t have told you what de minimis meant two years ago — mostly because they didn’t need to. It was the invisible infrastructure of cross-border trade, the threshold below which imported goods pass through customs without duties or taxes. And in the United States, that threshold sat at $800. For small online sellers sourcing internationally, it wasn’t a technicality — it was their business model. Now, that model is over.

De minimis was deliberate trade policy built on simple logic: the cost of collecting duties on a $25 phone case exceeds the revenue it generates. Let low-value goods flow freely, the thinking went, and e-commerce would grow — and it did.

The Trump administration’s first moves targeted Canada, Mexico, and China on fentanyl-related grounds. Then came Executive Order 14324, suspending duty-free de minimis for all countries effective August 29, 2025. Sellers who had never filed a customs entry suddenly had to file informal entries for goods valued up to $2,500 — and pay tariffs on every single one. Last count, that has meant $175 billion in tariffs paid annually, with small shipments accounting for roughly 63% of that.

The legal basis for Trump’s tariffs — the International Emergency Economic Powers Act (IEEPA) — went to the Supreme Court, which constrained presidential authority to pass these tariffs. Many sellers took that as a signal that tariff refunds were coming — they shouldn’t have.

Then came the legislative layer that changed everything. The One Big Beautiful Bill Act (OBBBA) — H.R. 1, now law — codifies the end of de minimis under Title 19 with a statutory end date of July 1, 2027. Buried in the legislative history, however, is language explicitly stating that nothing in the bill limits the president’s existing authority to restrict de minimis before that date. The current suspension has congressional cover, meaning that any court challenge faces a much tighter call than it would have had a year ago.

What most sellers are getting wrong

What’s making matters worse, however, is that many small e-commerce merchants may not fully understand all the nuances of the laws and regulations they are trying to navigate. Indeed, there are certain aspects of the situation that many are getting wrong, including:

The 2027 date is a headline, not a lifeline — When the ne Big Beautiful Bill passed with a July 1, 2027, , many sellers assumed they had a transition period — time to adjust pricing, renegotiate supplier terms, and build a compliance infrastructure. Buried in House Report 119-106, however, is language explicitly stating that nothing in the bill limits the president’s existing authority to restrict de minimis before that date. Congress didn’t create breathing room; rather, it codified the end while leaving the accelerator fully intact. The 2027 date is when de minimis ends by law. Indeed, it could end sooner — and effectively already has.

The Supreme Court decision didn’t unlock refunds — The Court’s IEEPA ruling was significant, but the administration’s response was swift: reimposed the suspension of tariffs under Section 1321 authority as of February 24. The tariff meter never stopped; and now, with the OBBBA’s legislative history providing congressional cover, the — which specifically addresses whether sellers are entitled to refunds in the de minimis context — faces a much harder statutory construction argument than it would have a year ago. This may mean that the Supreme Court win was a legal victory that may not translate into money back.

The refund process just lost its test case — For sellers hoping to recover duties paid, the most practical path was through the KAPE system run by the U.S. Customs and Border Protection (CBP) — a workaround allowing refund claims to feed directly into anĚýĚýfor verification. The lead case proving out that process, , just settled. Now, the trade legal community has to start over with a new test case, and nobody knows how long that is going to take. Sellers who filed protests rather than complaints at the Court of International Trade (CIT) are in a particularly difficult position — protests have time limits, and the CBP is under court order to re-liquidate open ones. Which legal bucket your entries fall into matters enormously right now.

The bottom line

The de minimis era enabled a generation of small merchants to compete globally on terms that would have been unimaginable 20 years ago. Its sunset doesn’t mean the end of cross-border e-commerce — but it does mean the end of operating on assumptions. The 2027 date, the Supreme Court decision, the refund process — each looked like relief and turned out to be more complicated than the headline suggested.

E-commerce merchants impacted by these de minimis developments need to talk to a trade attorney — not for the basics, but to understand where your claims stand, whether your protest strategy is still viable, and what the Atmus settlement means for you.

The storm isn’t over — and it may be more complicated than most sellers have been told.

Key takeaways:

• • • Profits continue to be strong — Most tax & accounting firms saw revenues and profits increase in 2025 despite a chronic talent shortage and other systemic challenges.

    • Optimism around AI adoption — Tax professionals are generally optimistic about AI-enhanced technologies, and their firms are backing their optimism with unprecedented levels of investment.

    • Expansion of advisory services — Firms are expanding their advisory service offerings to clients in such areas as tax strategy and business consulting, fueling growth and providing opportunities for competitive differentiation.

Tax, audit & accounting firm professionals have been concerned for years that the one-two punch of do-it-yourself tax software and automation might eventually erode the value of —and demand for — their services. However, according to the Thomson Reuters Institute’s “2026 State of Tax Professionals Report”, which surveyed more than 600 tax professionals worldwide, firms of all sizes are adapting remarkably well to the current era of rapid technological change and political upheaval.

Indeed, tax professionals surveyed say that, in addition to traditional tax preparation, their customers want and need more advisory services, a trend that has been gaining momentum for several years. In response, many firms are continuing to expand their service offerings in the areas of tax strategy, business consulting, decision support, and financial planning — especially at larger firms with more abundant resources.

The result of this gradual shift in service offerings is that profit margins for tax & accounting firms worldwide averaged about 30% in 2025, with some firms registering profit margins of more than 40%.

Efficiency and growth were top strategic priorities

When asked about their top strategic priorities for the coming year, survey respondents cite efficiency and promoting firm growth as the top factors on the strategic agenda for 2026, even more emphatically than they did in 2025.

Further, they see that making more and better use of technology is still the most immediate path to greater efficiency, Ěýwhich is why introducing additional automation and AI — or just trying to get the most out of a firm’s existing technology stack — was also mentioned as an important focus for the upcoming year.

Still searching for solutions to talent challenges

Challenges still abound, however. An anemic pipeline of new talent and the ongoing retirement of senior personnel are among the top barriers to progress and profitability at many firms, the report indicates. The report also notes that the resulting competition for qualified candidates leads to overwork, skills gaps, and capacity restraints, all of which can impede a firm’s ability to compete and grow.

Many respondents say their firms are using multiple strategies to address these issues, including more targeted training, career development, outsourcing, task reallocation, and automation. Competition for top talent is intense, nevertheless; and the report shows that midsize tax firms may feel the talent squeeze harder than others, chiefly because larger firms can offer higher salaries and more career opportunities to retain top talent.

Another way firms are addressing their talent challenges is by automating more tax processes and workflows; however, the report also suggests that many firms have reached the point in their technological maturity at which it may be more difficult to identify additional processes to be automated. As a result, these firms find themselves in somewhat of a holding pattern, unable to advance technologically because of unyielding systemic and cultural impediments.

Meanwhile, many larger firms have already built the technological infrastructures they need to support more advanced forms of automation and data analysis. Now, the report reveals, these firms are shifting their focus to make better use of workflow-enhancing tools that can enable more efficient operations, expand their firm’s capabilities, and serve as a competitive differentiator.

Not surprisingly, the conversation around AI is heating up as well. While tax professionals may not be so interested in public chatbots such as Claude and ChatGPT, their attention is directed toward the many ways in which AI can enhance the tools they already use and how intelligent deployment of these tools can benefit their firms. Indeed, AI was the only category of technological investment which experienced year-on-year budget growth, the report shows.

Overall, the “2026 State of Tax Professionals Report” offers invaluable insight into where tax professionals see their firms and their industry now, shedding light on how the world’s top tax leaders are advancing the profession.

Key takeaways:

• • • Mandatory compliance mandates are growing — Pillar 2, DAC6, and other real-time reporting mandates are increasing obligations in dozens of jurisdictions today, and those tax departments without the infrastructure to meet these obligations are already behind.

    • Real-time documentation is critical — The window between a transaction occurring and a tax authority scrutinizing it is shrinking to near zero in some markets, meaning that documentation must exist at the moment it is generated, not reconstructed afterward.

    • Data quality is compliance quality — Real-time compliance brings with it heightened pressure to avoid incomplete or inconsistent inputs, because increasingly sophisticated analytics used by tax authorities will find them.

In 2023, a major European manufacturer was hit with a seven-figure penalty not because its tax return was wrong, but because it couldn’t demonstrate how it arrived at the right answer. No documented governance framework, no clear ownership, and no audit trail. The numbers were defensible, but the process wasn’t.

That gap — between getting the right answer and being able to prove it — is where corporate tax risk now lives.

Governments and tax authorities worldwide are to self-report accurately. They are building legal frameworks, digital infrastructure, and enforcement mechanisms to verify compliance in real time. And for tax departments accustomed to managing compliance on their own terms, the window for a comfortable transition is closing fast.

A global tightening

Tax governance requirements are intensifying on multiple fronts. In the United States, for example, the IRS’s Large Business & International division has significantly expanded its compliance campaigns, targeting transfer pricing, research & development (R&D) credits, and multinational structures. Section 174 of the 2017 Tax Cuts and Jobs Act now requires companies to amortize R&D expenditures over five or 15 years depending on where research occurs — a change that many tax departments are still working through while absorbing new obligations on top of it.

Internationally, the pace is faster still. The framework that the Organisation for Economic Co-operation and Development (OECD) created for its base erosion and profit shifting (BEPS) rules has been adopted by more than 135 countries. Pillar 2 — the global 15% minimum corporate tax rate — is already in effect in dozens of jurisdictions and is actively reshaping how multinationals structure their tax affairs. These are not coming changes — they are current ones.

Mandatory disclosure regimes have expanded in parallel. The European Union’s DAC6 directive requires intermediaries and taxpayers to report potentially aggressive cross-border arrangements, with penalties in some member states reaching hundreds of thousands of euros. The United Kingdom’s Senior Accounting Officer regime goes even further, placing personal legal accountability on named senior executives for the adequacy of their company’s tax accounting arrangements. Similar regimes are expanding in Australia, Canada, and Brazil.

These are not isolated experiments. They represent that is not going to reverse any time soon.

The real-time reporting challenge

That means, corporate tax departments must respond to this shift because the traditional audit model — authorities review historical returns and request documentation years later — is being replaced in a growing number of markets. Spain, Hungary, and South Korea already require taxpayers to submit transactional data directly to tax authorities through mandatory electronic systems. The EU’s Value added tax (VAT) in the Digital Age initiative will extend similar requirements across all 27 member states beginning in 2028.

For tax departments, this reporting compression is the central operational challenge of the next five years. A team that once had 12 to 18 months to reconstruct documentation for an audit now needs that documentation to be accurate and defensible at the moment it is generated. That requires a fundamentally different operating model — not just better record-keeping, but automated data capture and real-time reconciliation built into core financial systems — along with the ability to transfer that documentation electronically in real time.

3 actions tax departments must take now

To begin to address this dramatic change, corporate tax departments need to act now, taking steps that include:

1. Building a formal governance framework

Tax departments need written governance frameworks that clearly define what party owns each compliance decision, how decisions are reviewed and approved, and what controls exist to catch errors before filing. This means named ownership of obligations, documented sign-off processes, and regular internal reviews against a compliance calendar.

In the UK, this is already a legal requirement ; and similar standards are emerging in Germany, Australia, and across the EU. A framework should cover at minimum; the ownership of each material filing obligation; the review and approval chain for positions taken; escalation procedures for uncertain tax positions; and a schedule for internal control testing. Without these processes in place, tax departments could face regulatory penalties, personal liability for senior leaders, and reputational damage that may be difficult to recover from.

2. Fixing the data access problem

Tax departments consistently lack reliable, timely access to the financial data they need. This is primarily an organizational problem, not a technology one. Tax functions often sit downstream from finance systems designed without tax requirements in mind — meaning data often arrives aggregated, reclassified, or stripped of the granularity needed for compliance work.

Solving this requires tax leaders such as finance, IT, and business operations — not just to request data, but to influence how that data is captured at its source. That means participating in enterprise resource planning implementations, establishing data requirements for new business lines before they launch, and building direct feeds from source systems rather than relying on manual extracts.

3. Treating data hygiene as a compliance control

Tax authorities in the UK, the Netherlands, Germany, and the US are deploying advanced analytics to identify anomalies in corporate filings. Unexplained variances between statutory accounts and tax returns, inconsistencies in intercompany pricing, or mismatches between VAT and corporate income tax data could all trigger closer scrutiny.

Data hygiene must be treated as a compliance control, not an IT issue. In practice that means establishing reconciliation checkpoints between source data and tax inputs, maintaining documented data lineage so any figure in a return can be traced to its source, and conducting data quality reviews before filing deadlines — not after.

The bottom line

The regulatory trajectory is set, so that means the question for tax leaders whether their department will be ready when tested. Governance, data access, and data quality are no longer back-office concerns — they are the foundation upon which defensible compliance is now built.

Tax department leaders need to build that foundation now, before the examiner asks.

Key insights:

• • • Real-time tax compliance has restructured the tax function — Dozens of nations now require structured invoice data in real time, with the EU mandating cross-border digital reporting by 2030. The traditional file-and-wait audit cycle is gone now, replaced by clearance regimes that can freeze multi-million-dollar invoices for nonconforming data.

    • Regulators have pulled ahead of the businesses they oversee — Tax authorities in mature CTC jurisdictions now arrive at audits with structured transaction data already processed by their own analytics. Government turnaround times that took months now take weeks, forcing multinational tax leaders to compress multi-year roadmaps into 12- and 18-month cycles to keep up.

    • The lessons travel beyond tax — There are two ways to lose this race: Outrun your own controls or surrender entirely. Both showed up in Las Vegas, and both will show up in every other regulated profession over the next decade.

LAS VEGAS — TheĚý sold out. A guest list that included tax directors from Amazon, Walmart, and Procter & Gamble, OpenAI’s tax department, the Big Four, ¶¶ŇőłÉÄę and every other major tax software provider in the market spent three days at the Aria with pool deck, casino floor, and restaurants worth lingering over all a few steps away.

The room had every reason to spend its evenings somewhere else other than a sunless conference room talking about tax. Yet almost no one did. They were too busy grappling with an arms race the corporate audit side had begun to suspect it was losing.

And it’s one they cannot afford to lose.

End of the traditional model

The arms race is real-time tax compliance, and it has dramatically restructured the ground beneath the tax profession in less than a decade. By April, more than 60 jurisdictions have moved or are moving to continuous transaction controls. Italy and Hungary were early; Poland, France, Belgium, Brazil, Saudi Arabia, India, and Singapore are now operational or imminent, and countries like Spain, Germany, the United Kingdom and the United Arab Emirates are on the way. The European Union has locked onto a 2030 deadline for cross-border real-time digital reporting and a 2035 backstop for harmonizing what’s left.

The traditional model — issue an invoice, file a return weeks later, audit when the auditor gets around to it — no longer exists in those jurisdictions. Tax authorities now see the transaction as it happens, validates it in structured form, and pre-fills the return on the taxpayer’s behalf.

What this new process has done to the tax function is fundamentally alter its structure in a way leaves practitioners reeling. The job used to be a craft of Excel, judgment, and institutional memory. Now, at the high end, it has become as much a data science problem as an accounting one.

The arms race is real-time tax compliance, and it has dramatically restructured the ground beneath the tax profession in less than a decade.

Attendees at TEI’s 2026 Tax Technology Seminar polled themselves on tooling, and the answers came back as a list of data pipelines that dozens of attendees seemed to favor: Alteryx, Power Platform, Snowflake, Databricks, Microsoft Fabric, & Palantir Foundry. These platforms are running agentic AI systems against historical filings, deploying validation agents to critique their own outputs, and using AI-driven image-to-text solutions to pull structured data out of state tax notices that never arrive in the same format twice. They are data integration pipelines in 15 minutes that would have sat in an IT queue for two months before being answered.

They have little choice as the stakes are far higher and the challenges far more demanding than they used to be. In a clearance regime, an invoice has no legal force until the tax authority returns its identifier. Did you submit the wrong VAT ID, malformed schema, or mismatched master data? Congratulations! Your invoice is rejected. That means the truck doesn’t move, the buyer doesn’t pay an invoice that may be in the millions of dollars and then the penalties stack on top. Italy, for instance, charges a fee of 70% of the disputed VAT.

And then there are the audits.

Outgunned

The audit isn’t an occasional event anymore. In government jurisdictions with mature continuous-transaction-control tax regimes, it is a conversation that started weeks before the auditor walked in, on data their analytics had already processed.

A speaker on a seminar panel led by Deloitte and ¶¶ŇőłÉÄę described the dynamic plainly: Tax authorities in those jurisdictions have arrived at audits already knowing more about the transactions than the companies and their in-house audit teams sitting across the table. Not because anyone is hiding anything, but because the data arrived at the tax authority in structured form, in real time, and the authority had run its analytics on it before the meeting was even on the calendar. One panelist said this represents “a shift from us preparing returns to us answering notices on the data that’s been shared.”

What the room kept circling around, however, was that regulators have not just kept pace with their counterparties, they’ve now pulled ahead. Singapore, one panelist noted, is doing more with AI than even major companies. Indeed, government turnaround times that used to take months are now closing in weeks, which is forcing multinational tax leaders to compress their multi-year roadmaps into 12- and 18-month cycles — not because they want to but because their counterparties already had.

The lesson that corporate tax functions have been forced to absorb is that there are two ways to lose this race, and both were on display at TEI’s 2026 Tax Technology Seminar as cautionary tales.

This asymmetry is structural, and that is what makes it an arms race rather than a transition. There is no version of this dynamic in which the company being audited wins by being more careful, more thorough, or more well-prepared at the end of the quarter. The advantage now accrues to the side with the fastest and cleanest pipelines, that runs the smartest AI, and that understands the way these increasingly complex systems interact. Increasingly, that winning side is the government. And, more alarming, this isn’t just a problem for this particular industry — tax just happened to get here first. However, it’s coming for everyone.

Two ways to lose

The lesson that corporate tax functions have been forced to absorb is that there are two ways to lose this race, and both were on display at TEI’s 2026 Tax Technology Seminar as cautionary tales. The first is to outrun your own controls. AI coding tools that let a tax analyst build a working data integration pipeline in 15 minutes are genuinely valuable; they also let that same analyst deploy something nobody else has reviewed, documented, or knows how to maintain. An OpenAI panelist conceded the point when an audience member asked about the security implications of vibe coding — clearly, a new capability is also a new problem.

The second way to lose is harder to talk about. One panelist described, to attendees’ general dismay, hearing of companies that have given up on compliance entirely — instead, they pad their numbers with a safety margin and treat the eventual audit as the cheaper of the two costs. The panel recoiled — one member responded with a flat “Do not do this.” However, the anecdote landed because it isn’t theoretical. When the gap between what regulators can see and what your team can produce becomes wide enough, surrender starts to look rational.

Playing to win

Of course, the attendees at TEI’s 2026 Tax Technology Seminar were not surrendering. If they were, they’d have been at the pool deep into their third cocktail. Or they’d have been on the casino floor or were about to catch an afternoon show. Instead, day after day, the tables filled, the exhibit hall ran hot, and the room was buying, listening, and building.

The game has changed and the stakes have risen — and the room is dead set on playing to win.

• • • The reactive phase is partly a mindset problem — More than half of tax departments remain stuck in reactive, compliance-focused operations, not only because of frozen budgets, but because of cost-center thinking that shapes cost-center behavior.

    • The value is there, but the measurement isn’t — Two-thirds of tax professionals say their department’s technology investment has already enabled more strategic work; yet 22% say they track no performance metrics at all, making that value invisible to the people who control the budget.

    • The rebrand starts internally — With AI integration timelines compressing to between 1 and 2 years, tax departments that shift their posture now by measuring wins, designating leadership, and building the business case will be better positioned to lead — and those that don’t will fall further behind, faster.

Apart from the sales department, most other departments within a business are simply viewed as a cost center, and the tax department is no exception. However, like so much of that thinking, this view isn’t quite accurate because it is the tax department that can uncover the most savings for the business.

You need not look further than recent data that shows while 67% of tax professionals say their department’s technology investment has already enabled them to do more strategic work, 22% say they track no performance metrics at all, making it difficult to demonstrate the tax department’s value to the C-Suite.

Given this, it’s somewhat unsurprising that this cost-center view persists. Worse yet, is often internalized by in-house tax teams themselves. It is one thing to be viewed and treated as a cost center but to act like one is a different matter.

So, what if the bigger problem isn’t how the rest of the business views the tax department but instead how the department views itself?

The , from the Thomson Reuters Institute and Tax Executives Institute, reveals a profession that knows it is capable of far more than it is currently delivering. And yet the same patterns repeat: Budgets stay flat, technology adoption stays slow, and a majority of departments remain stuck in a reactive phase in regard to their technological development that has “remained stubbornly consistent over the past few years,” according to the report.

That’s not just an organizational failure; rather, that’s a mindset problem — and it starts from within the tax department.

The choices we keep making

The report outlines a Technology Maturity Curve that maps a progression in tech development from chaotic through reactive, proactive, optimized, and predictive stages.

This year, 64% of respondents placed their tax department at the chaotic or reactive end of the spectrum — up from 57% last year. The reactive phase is the operational definition of a cost center: Heads-down, output-focused, and disconnected from the broader business.

The report reveals something even more important. In those cases in which the budget isn’t the primary constraint, behavior doesn’t change. Almost one-third of respondents (32%) said their strategy for addressing capacity constraints is process optimization — without new technology or additional hiring. Not because they can’t pursue more, but because that’s the default mode.

One respondent put it plainly: “…Our company as a whole is making significant changes, but the tax department is typically an afterthought in those decisions.”

This raises a question that’s worth asking: Who taught the company to treat tax as an afterthought?

There’s evidence showing that tax departments are more

The data to challenge the cost-center identity isn’t missing; rather, it’s just not being captured or communicated to the C-Suite.

Two-thirds of respondents (67%) said their tax department’s technology investment over the past three years has already enabled a shift toward more strategic, proactive work, such as data analytics, forecasting, risk assessment, and decision-making support. Among larger departments, nearly half (48%) are now spending more time on these higher-value activities. This clearly shows that companies that have invested in tax automation are reporting real results, such as improved accuracy, reduced errors, lower costs, and streamlined workflows.

And yet, 22% of tax departments track no technology performance metrics at all, according to the report — not time savings, not error reduction, not ROI. Nothing.

While 67% of tax professionals say their department’s technology investment has already enabled them to do more strategic work, 22% say they track no performance metrics at all, making it difficult to demonstrate the tax department’s value to the C-Suite.

That is cost-center thinking in action — the belief that it’s the job of the tax department to do the work, but not to prove its value. However, what isn’t measured can’t be communicated — and what can’t be communicated can’t change the perception, either internally or externally.

The rebrand starts with how departments see themselves

The most important audience for the tax department’s rebrand isn’t the C-Suite. It’s the department itself.

That means tracking wins and building a formal business case for investment — grounded in hard ROI and cost savings, which the report identifies as the metrics that are most important to Finance and IT, the two functions that frequently share control of the tax technology budget.

It also means getting serious about leadership. The portion of tax departments with a designated person leading tax technology strategy jumped to 88%, from 51%, in a single year. However, a title only goes so far; and the report is clear — that role only works when backed by a team that believes it belongs at the decision-making table.

Finally, this rebranding means treating AI as an opportunity, not a threat. The majority of tax professionals have compressed their expectations for AI integration to 1–2 years, from 3–5 years, with 7% saying AI is already central to their workflow. Those departments still locked in cost-center mode are the least prepared for that shift — because cost centers don’t invest ahead of the curve.

The narrative changes when the mindset changes

No one is going to rebrand the tax department on its own, it has to come from within. Further, it has to be built through deliberate measurement, consistent communication, and a shift in how tax professionals think about our own work.

Your department is not a cost center. The work proves it, and the data backs it up. Now, you should act like you believe it.
