A new report by the National Audit Office has raised serious questions about how HMRC tackles tax avoidance and non-compliance among the UK’s wealthiest individuals. The findings paint a picture of limited strategy, a lack of transparency, and worrying gaps in skilled enforcement — all at a time when public trust in the fairness of the tax system is under strain.
The NAO’s report makes clear that HMRC knows far more than it tells. Internally, it has identified a much larger sum of tax at risk from offshore non-compliance than it publishes. This hidden figure, linked to the complex tax affairs of wealthy individuals using offshore structures, remains undisclosed to the public — a decision the NAO suggests undermines transparency and weakens public confidence. When ordinary taxpayers see cuts to services while wealthy individuals appear to escape proper scrutiny, the social contract starts to fray.
The wealthy, defined here as individuals with over £10 million in assets or high levels of income, are often in a better position than most to exploit loopholes and complex tax arrangements. Yet, despite this, HMRC has adopted what the NAO calls only a “limited strategy” to address non-compliance in this group. The report warns that this piecemeal approach lacks the overarching vision or coherence needed to systematically close tax gaps and deter wrongdoing.
Adding to the concern is a resourcing issue. In the Autumn Budget, the government announced funding for an extra 5,500 compliance staff over the next five years. While this sounds impressive on paper, the NAO cautions that there’s no clear plan to ensure that these roles are filled with people who have the right expertise to investigate sophisticated financial arrangements. The question isn’t just about numbers — it’s about capability. Tackling high-end avoidance isn’t the same as chasing unpaid PAYE or VAT; it requires specialist knowledge, legal insight, and investigative skill.
The NAO makes several recommendations. Chief among them is the call for HMRC to develop a clear, strategic plan specifically aimed at wealthy non-compliance. It also urges the department to be more open about the scale of the problem — arguing that greater transparency could reassure the public and act as a deterrent to those tempted to push the boundaries.
The report’s message is that fairness matters — and is not just about outcomes, but visibility. When ordinary working people are held to strict compliance and face fines for minor mistakes, the perception that the rich play by a different set of rules corrodes the legitimacy of the entire system.
For those advocating tax justice and a fairer society, the NAO’s findings offer a powerful tool. They expose the need for structural reform in how the tax authorities approach the powerful — and remind us that without scrutiny, fairness is just a slogan. The next step must be political will: not only to fund enforcement, but to demand the transparency and accountability that a healthy democracy requires.
