HMRC Bolsters Fraud Investigation Team: Will It Deliver?

In a move signalling a tougher stance on tax evasion, HM Revenue and Customs (HMRC) has announced plans to expand its Fraud Investigation Service (FIS) and increase prosecutions for serious tax fraud by 20% by 2029-30, raising the annual target from 500 to 600 cases. This initiative, coupled with intensified efforts like increased "dawn raids" and a focus on "phoenixisation" schemes, reflects the UK government’s commitment to closing the £7.5 billion tax gap. But will this expansion translate into meaningful action, achieve its goals, and target high-value offenders, or will it merely sweep up low-hanging fruit?

The Expansion: What’s Happening?

HMRC’s strategy involves bolstering its counter-fraud capabilities, with a focus on individual and corporate tax evasion. The agency has already ramped up property searches, averaging 648 "dawn raids" annually, a clear escalation in its enforcement tactics. Additionally, HMRC is targeting complex fraud schemes like "phoenixisation," where businesses use contrived insolvencies to dodge tax liabilities. The government is also introducing a whistleblower incentive scheme, modelled on U.S. practices, to encourage tip-offs on tax dodgers, potentially rewarding informants with a percentage of recovered funds.

 

This push comes amid political pressure to boost public coffers, particularly after HMRC reported a £9.5 billion VAT gap in 2023-24. The agency’s collaboration with entities like the Insolvency Service and Kent Police, as seen in a recent case uncovering a £22 million tax fraud, underscores its intent to tackle sophisticated schemes. However, the decline in prosecutions of tax fraud enablers—down from 16 in 2018-19 to fewer than five in 2023-24—raises questions about HMRC’s track record.

Will It Actually Happen?

The expansion is plausible, given the government’s fiscal priorities and public support for cracking down on tax evasion. Chancellor Rachel Reeves has secured the Office for Budget Responsibility’s approval for the £7.5 billion tax gap reduction target, lending credibility to the plan. HMRC’s recruitment of additional staff and investment in investigative tools, such as data analytics, further suggest that the infrastructure for expansion is being built.

 

However, challenges loom. HMRC has faced criticism for staff retention issues and resource constraints, which contributed to a six-year low in serious tax fraud investigations (480 cases in 2023-24, down from 1,091 the previous year). These limitations could hamper the agency’s ability to scale up effectively. Moreover, criminal investigations are complex and time-consuming, often spanning years, which may delay visible results. The reliance on whistleblowers also introduces uncertainty, as the success of the incentive scheme depends on public willingness to come forward and the quality of information provided.

Will It Be Successful?

Success hinges on how we define it. If the goal is to increase prosecution numbers by 20%, HMRC’s enhanced resources and political backing make this achievable. The agency’s £1.1 billion tax recovery in 2023-24, albeit inflated by a single £652.6 million settlement, demonstrates its capacity to secure significant sums. Partnerships with other agencies, like the Insolvency Service for COVID fraud cases, could further amplify outcomes.

 

Yet, the broader aim of closing the tax gap may prove elusive. The £9.5 billion VAT gap and £8.2 billion in inheritance tax duties collected last year highlight the scale of evasion. Critics, including TaxWatch, argue that HMRC’s data reliability issues and declining prosecution rates for enablers suggest systemic weaknesses. Without addressing these, the agency risks focusing on quantity over quality, potentially missing high-value targets. The National Audit Office has also noted HMRC’s lack of a clear strategy to combat small business tax evasion, which accounts for £4.4 billion annually.

Low-Hanging Fruit or High-Value Targets?

A critical concern is whether HMRC will prioritise easily prosecutable cases—low-hanging fruit—or pursue complex, high-value offenders. Recent trends suggest a mixed approach. The focus on "highest-harm and highest-value fraud" indicates an intent to target sophisticated schemes, as seen in the Kent Police collaboration that dismantled a £22 million VAT fraud. However, the sharp rise in inheritance tax investigations (3,961 in 2023-24, up 31% from the prior year) suggests HMRC is also leaning on straightforward cases, such as errors or undervalued assets in estates, which are easier to investigate.

 

The decline in prosecutions of enablers—those who facilitate tax evasion—further fuels scepticism. These cases are resource-intensive and require unravelling complex networks, yet they yield significant deterrence. HMRC’s claim of having 150 enablers under investigation is promising, but the drop from 16 to fewer than five prosecutions in five years suggests a preference for simpler cases. The whistleblower scheme could shift this balance by uncovering high-profile offenders, but its impact remains speculative.

Critical Perspective: Beyond the Headlines

While HMRC’s expansion is a step toward accountability, it risks becoming a performative exercise if it prioritises easy wins over systemic reform. The agency’s history of unreliable data and declining investigations undermines confidence in its ability to deliver. Political pressure may drive HMRC to inflate prosecution numbers with low-level cases, leaving wealthy tax dodgers and enablers unscathed. Moreover, the focus on individual prosecutions ignores broader structural issues, such as loopholes exploited by corporations or the underfunding of HMRC’s investigative arm.

Conclusion

HMRC’s plan to expand its fraud investigation team and boost prosecutions is feasible, backed by political will and resource allocation. However, success is not guaranteed. Resource constraints, data issues, and a history of declining investigations could limit impact, while the focus on numerical targets risks prioritising low-hanging fruit over high-value offenders. For the initiative to truly close the tax gap, HMRC must balance its pursuit of easy cases with a relentless focus on complex fraudsters and enablers, ensuring that the crackdown delivers both justice and deterrence. Without this, the expansion may amount to little more than a headline-grabbing gesture.

Tax does have to be taxing.
