FROM THE RICHARD ALLEN CASE TO HMRC REFORM: WHISTLEBLOWERS AND THE FRONTIER OF TAX ENFORCEMENT

Taxation and Veil of Secrecy

In recent months, tax whistleblowing has shifted from a mere compliance tool to a structural lever for criminal and tax enforcement, with a growing convergence toward economic incentive models.

World Whistleblower Day, therefore, provides an important opportunity to reflect on the increasingly central role that internal reporting is playing in the prevention and countering of economic, financial, and tax crime.

In recent years, whistleblowing has progressively moved away from its traditional ethical or reputational dimension to become a structural tool for enforcement. While in the past reports were predominantly considered a safeguard for corporate compliance, today they increasingly represent an essential source of information for judicial authorities, tax administrations, and regulatory bodies.

In this context, the most significant evolution in recent months comes from the United Kingdom, where the topic of tax whistleblowing has taken center stage in public and institutional debate. However, to fully grasp its scope, it is useful to reconstruct the path that led here.

The Richard Allen Case: The Story of an Unrewarded Whistleblower

Among the most emblematic cases that fueled the debate on the British reform is that of Richard Allen, founder of the mail-order music company Delerium Mail Order and spokesperson for the association Retailers Against VAT Abuse Schemes (RAVAS).

Beginning in 2005, Allen started exposing the existence of a fraudulent scheme linked to the VAT exemption for the Channel Islands (Low Value Consignment Relief, LVCR), which allowed low-value goods to be imported into the UK without the application of VAT. Certain operators exploited this mechanism by shipping goods from British ports to the Channel Islands and then reintroducing them into the country, thus systematically bypassing the tax.

His reporting and advocacy activities proved crucial in bringing the matter to the attention of the UK Parliament's Public Accounts Committee, helping launch the process that led to the progressive closure of the scheme. Reflecting on the personal toll of competing against this tax evasion before it was addressed, Allen testified to the Committee: "It happened to me... By that point, it was unsustainable; we just had to close. [...] There were 10 staff and our total turnover, including assets, was over £1 million. It was impossible to compete in the end" (https://perma.cc/AJ2Z-PKEY).

Despite his contribution, it took HMRC years to intervene decisively, allowing similar schemes related to global e-commerce imports to continue in the meantime. Subsequently, Allen himself became embroiled in a dispute with the British tax administration, which concluded with him being ordered to pay hefty legal fees. His complaint to the Parliamentary and Health Service Ombudsman (PHSO) was rejected; he later expressed doubts regarding the actual independence of the institution.

The case became emblematic of a structural dysfunction: the absence of transparent and proportional recognition mechanisms for whistleblowers, combined with exposure to significant economic and reputational risks (see Bailiwick Express Report, https://perma.cc/N8KM-FY38).

The British Turning Point: The Strengthened Reward Scheme

In March 2025, HM Revenue & Customs (HMRC) announced a new, enhanced reward program for whistleblowers, which was subsequently confirmed in the Autumn Budget on November 26, 2025. The new model, named the Strengthened Reward Scheme, operates alongside the previous discretionary regime.

The new model introduces the possibility of granting a financial reward ranging between 15% and 30% of the recovered taxes for reports leading to the recovery of at least £1.5 million, with no maximum cap (https://www.cliffordchance.com/insights/resources/blogs/regulatory-investigations-financial-crime-insights/2025/12/a-sign-of-things-to-come-hmrc-launches-informants-rewards-for-tax-evasion-cases.html).

The contrast with the previous system is striking: in 2024, HMRC had paid out approximately £852,000 in total across more than 160,000 reports received (https://www.taxadvisermagazine.com/article/cash-information-how-hmrc-paying-intelligence)

The underlying benchmark is the US Internal Revenue Service (IRS) model, active since 2006, which has enabled the recovery of over $7 billion, with total awards exceeding $1.3 billion (https://www.taf.org/the-united-kingdoms-hmrc-new-tax-reward-program/). It is also telling that more than 700 British whistleblowers have chosen to turn to the US system since 2012, which is deemed more effective due to its incentive mechanisms (https://www.whistleblowers.org/news/uk-new-whistleblower-program-historic-shift/).

Nevertheless, several critical elements remain: the discretionary nature of the award, the lack of a statutory right to the reward, the exclusion of anonymous reports, and limited procedural transparency (https://www.macfarlanes.com/insights/102lwst/new-hmrc-reward-scheme-for-whistleblowers-introduced/).

From Document Audits to Human Intelligence

The growing focus on whistleblowing reflects a deeper shift in strategies to combat economic crime.

The most sophisticated tax frauds are characterized by complex organizational structures, formally correct documentation, and processes designed to appear fully compliant with regulations.

In these contexts, information originating from inside the organization holds an investigative value that is difficult to replicate through traditional audit tools.

The whistleblower does not merely report a fact: they often help reconstruct the inner workings of fraudulent schemes, clarifying operating methods, roles, and objectives. It is no coincidence that many of the most significant investigations of recent decades originated from internal disclosures (https://wilmerhale.com/en/insights/blogs/wilmerhale-w-i-r-e-uk/20251202-budget-2025-hmrc-whistleblower-scheme-a-welcome-change).

The European Framework: Protection Yes, Incentives No

The British experience sits within a European context that has adopted a radically different approach, based on protecting the reporter rather than offering financial validation. The benchmark regulatory framework is Directive (EU) 2019/1937, adopted on October 23, 2019, and entering into force on December 16 of the same year, which introduced common minimum protection standards across all Member States, particularly regarding breaches of Union law in strategic sectors such as public procurement, financial services, privacy protection, and cybersecurity.

The philosophy of the Directive is essentially protective. The central goal of the European legislator is to guarantee robust protection for the reporter against retaliation—including reinstatement, compensation for damages, and the reversal of the burden of proof—while ensuring the availability of reliable and confidential internal and external reporting channels. In this design, the European Union has chosen, at least until now, not to introduce economic incentive mechanisms. This choice reflects an institutional tradition shared by many continental jurisdictions, according to which reporting wrongdoing is primarily a civic and moral duty, not an activity to be remunerated.

However, this approach risks showing clear limits in terms of pragmatic effectiveness. Legal protection from retaliation alone may not suffice to offset the devastating economic, professional, and personal costs that those who decide to step forward almost systematically face. Consequently, the gap with the North American model (where reward systems demonstrate a capacity to generate human intelligence that is difficult to replicate via traditional inspection tools) is bound to become a political and legal knot that will be increasingly hard to ignore in the European debate.

The Italian experience offers an illuminating example of this tension between formal protection and substantive efficacy. The transposition of the Directive into the Italian legal framework occurred through Legislative Decree No. 24 of March 10, 2023 (entering into force on March 30 of the same year), accumulating a significant delay compared to the original deadline of December 17, 2021; a delay that had prompted the European Commission to refer Italy, along with seven other Member States, to the Court of Justice of the European Union (https://www.transparency.it/informati/news/direttiva-whistleblowing-commissione-europea-deferisce-italia).

The Italian decree progressively extended the obligations to set up internal reporting channels to the private sector, staging them by company size: by July 15, 2023, for all companies with more than 250 employees, and by December 17, 2023, for those with a workforce between 50 and 249 employees (https://www.anticorruzione.it/-/busia-finalmente-l-italia-recepisce-definitivamente-la-direttiva-sul-whistleblowing). The resulting Italian regulatory framework aligns perfectly with the continental approach: it is a system entirely oriented toward the rigorous structuring of channels and the protection of the whistleblower, leaving the issue of financial incentives completely unaddressed and off the radar.

What emerges from this comparative analysis is thus a fundamental divergence that remains unresolved. While the Anglo-Saxon bloc, led by the historic US model and now followed by the United Kingdom, aims to maximize the flow of information and human intelligence by leveraging economic incentives, continental Europe privileges the protection of the whistleblower as an end in itself, anchoring it to the logic of fundamental rights rather than pure enforcement. The real challenge that the European legislator will face in the coming years will be to understand whether these two approaches must remain rigidly alternative, or whether it is instead possible, as well as desirable, to build a hybrid system capable of combining them in a coherent and effective manner.

A Challenge for Governance and Compliance

The growing centrality of whistleblowing poses new challenges for businesses and corporate governance systems.

The formal presence of reporting channels is no longer enough. What becomes decisive is their actual accessibility, credibility, and capacity to build trust among potential whistleblowers.

Furthermore, the British reform introduces a potential systemic effect: the tendency for whistleblowers to bypass internal corporate channels and go directly to tax authorities, thereby reducing organizations' ability to proactively manage issues (https://www.kingsleynapley.co.uk/insights/blogs/tax-law-and-hmrc-blog/hmrcs-strengthened-reward-scheme-for-whistleblowers-of-tax-avoidance-and-evasion).

Questions that are anything but minor remain open: the risk of opportunistic reporting, the management of the quality of information received, and the balance between investigative effectiveness and procedural guarantees.

On the occasion of World Whistleblower Day 2026, a clear initial conclusion emerges: whistleblowing is no longer just a compliance tool, but a structural component of the enforcement architecture against economic crime.

The path chosen by the United Kingdom points to a possible evolution of the European paradigm in the coming years, opening up an issue destined to become increasingly central in legal and institutional debate: whether and how it is possible to integrate protection and incentives within a single, coherent model for combating economic and tax offenses.
