How HMRC’s New Whistleblower Payments Will Encourage Reporting of Tax Evasion in 2025

Budget 2025: HMRC to pay tax whistleblowers

How the New HMRC Reward Works

The Autumn Budget 2025 introduced a new whistleblower reward scheme for HMRC. Under this scheme, individuals who report high-value tax fraud can receive a cut of the recovered tax. Specifically, HMRC will pay rewards up to 30% of the additional tax collected in cases where over £1.5m is eventually reclaimed. In practice this means a tip that directly leads to a £1.5m tax recovery could earn at least £450,000 (30% of £1.5m) for the whistleblower. Importantly, rewards are paid discretionarily after investigations conclude – there is no guaranteed minimum payout.

Key points of the HMRC payments to whistleblowers scheme:

Eligibility: High-Value Cases Only

– High-value cases only: Whistleblowers qualify only if their information triggers HMRC to recover at least £1.5 million in tax.

– Generous reward percentages: Informants can earn 15–30% of the extra tax collected (after the £1.5m threshold), excluding penalties and interest.

– Discretionary payouts: All rewards remain at HMRC’s discretion; tips alone don’t guarantee payment. Payments are made only after a successful investigation and tax recovery.

– US-inspired model: The new UK scheme closely follows the US IRS whistleblower program. In the US, informants routinely receive 15–30% of recovered taxes, and agencies have awarded whistleblowers

billions of dollars for tips leading to enforcement actions. The Budget proposal explicitly references this model.

These measures took effect immediately with the Budget announcement (from 26 November 2025). In summary, HMRC’s new payments to whistleblowers are aimed at rewarding informants who reveal large-scale tax evasion by major companies, wealthy individuals or complex offshore schemes. The government hopes this will help close the UK’s tax gap.

Impact and expert insights on whistleblower payments

Why Whistleblower Payouts Remain Modest

In practice, HMRC already receives very large numbers of fraud tips each year. For example, in 2024/25 the tax authority logged 164,670 anonymous fraud reports via its hotline. Despite this flood of intelligence, total rewards paid have been modest – around £850,000 in 2024/25. In fact, payouts fell 13% year-on-year even as tips rose, suggesting HMRC is being overwhelmed with low-value or unverified claims. As one report notes, this implies HMRC is “inundated with more low-value or unverifiable evidence” and fewer high-value leads that would merit payment.

Putting these figures in context: last year HMRC paid roughly £852,000 to informants (the previous year it was ~£978,000). This works out at just a few pounds on average per tip – evidence that most whistleblowers so far have reported minor issues. By contrast, under the new payments to whistleblowers scheme, a single big tip could earn hundreds of thousands. However, experts caution that not every tip will pay off. Investigations into large-scale tax fraud can take years (especially if court action follows), and HMRC will thoroughly verify leads before recovering tax.

Some analysts warn that the promise of big rewards could flood HMRC with tip-offs of varying quality. One commentator notes that investigating these reports demands “hefty resources” and that tips will range “from good, to well-meaning but unfounded, to out-and-out vexatious”. In other words, HMRC will need to sift through a lot of noise to find the genuine cases. Whistleblowers must also understand that payouts are not automatic – HMRC emphasizes that rewards will remain discretionary and case-dependent. A tipster can’t simply provide a name and expect a cheque; only actionable, verifiable intelligence will eventually generate a reward.

Key considerations:

Tip Volume vs Reward Value

– Tip volume vs reward value: HMRC recorded

~164,700 tips in 2024/25 but paid only about £850k in rewards, implying an average of ~£5 per tip. The new scheme aims to focus on the few high-value cases.

– Risk of speculative tips: Industry observers warn that many informants might submit incomplete or exaggerated reports in hope of a payout. As one analysis put it, HMRC may see a rise in “speculative, exaggerated or malicious claims”.

– No quick payoff: Large fraud investigations take time. Whistleblowers should expect a lengthy process, with any reward only paid after final tax recovery. There is “no free lunch” – tips won’t be “oven-ready” settlements.

– Enforcement boost: HMRC expects the scheme to supercharge its enforcement capabilities. City A.M. notes the new programme will “target higher-value tax fraud and is expected to supercharge the government’s enforcement capabilities”. In short, officials anticipate more resources devoted to pursuing the biggest tax cheats.

We advise all businesses and individuals to remain vigilant. Ensure your tax affairs are above board, as insiders may now be more inclined to report any questionable avoidance. If you need clarity on compliance or if you are approached by investigators, seek professional advice early.

Comparing UK and US whistleblower rewards

How the UK Follows the US System

The UK’s move mirrors an established US system. In the United States, the IRS and other agencies pay 15–30% of recovered taxes to whistleblowers, and over $1.3 billion has been awarded from billions recovered. American whistleblowers have exposed major fraud (often in financial services, healthcare, etc.) and have taken home multi-million dollar rewards. The UK scheme explicitly follows this model, though on a smaller scale. For context, in 2023/24 HMRC paid out nearly £1 million in fraud-tip rewards (up 92% from £508,500 in 2022/23). Those figures are still modest compared to US payouts, but the new rules could bridge the gap.

As the Reuters summary explains, informants in Britain could receive between 15% and 30% of recovered tax (excluding penalties and interest) for tips that lead to at least £1.5m collected. This is a significant shift from the previous UK approach, which offered only small flat payments. While the IRS program also excludes already-public information, the key lesson is that the UK now offers tangible financial incentives comparable to those abroad. HMRC hopes this will encourage “the reporting of high-value tax fraud and avoidance”, as noted by analysts.

Next steps for businesses and individuals

What Businesses Need to Know

What does this mean for you? For businesses of all sizes, the new whistleblower payments signal greater HMRC scrutiny ahead. Companies should double-check compliance in areas targeted by the government (for example, corporate tax planning and offshore transactions). It’s wise to tighten internal controls and reporting channels now, before tipsters come forward. Likewise, individuals who suspect tax wrongdoing have an added incentive to report it

If you are involved in or affected by any HMRC investigation (either as a potential whistleblower or as someone under scrutiny), professional guidance is essential. The rules and eligibility criteria can be complex. Our Naail & Co team is ready to advise on HMRC payments to whistleblowers, tax investigations and compliance strategy. Get in touch with Naail & Co to book a free initial consultation and ensure you fully understand your rights and options under the new scheme.

Conclusion

Budget 2025 has set the stage for “handsome rewards” to informants. Up to 30% of recovered tax (above £1.5m) will be paid out, but only when a successful investigation wraps up. While this could unearth hidden evasion, it also raises practical challenges. We encourage anyone with relevant information – or anyone facing an HMRC query – to seek specialist help. Naail & Co’s chartered accountants and tax advisers can help you navigate these changes and protect your interests.
