Perspective and Summary

Implications of an AI-Enabled HMRC

Citation

Josephine Cumbo, 'Wealthy Warned Over HMRC's Extensive Use of AI' FT Weekend (London, 11–12 July 2026) Money 3.

Summary

HMRC is using 'Connect', a data analytics tool that uses information across 'banks, online marketplaces, social media accounts ... property-letting agent databases and tax returns' [Josephine Cumbo] in order to identify potential non-compliance.

The concern is that the wealthy will face unprecedented levels of scrutiny in their tax affairs, and it is substantiated: HMRC has confirmed that digital analytics and surveillance tools helped bring in/protect ~£10bn in tax last fiscal year.

HMRC also incentivises whistleblowing through their 'Strengthened Reward Scheme' which rewards informants with 15–30% of the value of additional tax collected for recoveries over £1.5mn.

HMRC has also become increasingly willing to employ the law to pursue tax evaders. Its Fraud Investigations Unit secured 260 convictions in 2025–26.

Useful Quotes

Re HMRC's Enhanced Capabilities

Tim Stovold, Head of Tax at Moore Kingston Smith:

'There is a definite trend of HMRC collecting more data from the wealthy and [the] businesses they own'

'This includes plans to require companies to provide HMRC details on transactions with their shareholders, including cash withdrawals, loans, debts, dividends and transfers of assets to and from the company'

'Now, even with basic data analytics tools, once HMRC has this data, sifting it to identify taxable amounts omitted from tax returns becomes a straightforward exercise'

Ian Robotham, Partner at Pinsent Masons:

'The algorithms that [Connect] uses allow HMRC to spot anomalies that would otherwise go unnoticed by the human eye'

'With thousands of HMRC staff now using Connect, taxpayers are facing a level of oversight that would have been unthinkable just a few years ago'

'As Connect grows, taxpayers should expect far greater scrutiny of their financial affairs – and far fewer gaps left undetected'

Nicola Hine, Tax Disputes Partner at CMS:

'Taxpayers should be well organised to respond to HMRC inquiries, assessments and manage their compliance'

Re Whistleblowing Incentives

Hinesh Shah, Partner at Pinsent Masons:

'Once the publicity spreads and it is clear that substantial financial rewards are being given out then there will be a noticeable increase in the quality and quantity of whistleblower evidence being provided to HMRC'

'In those cases, the most significant whistleblower risk may arise from people with close knowledge of their financial arrangements, including former employees, personal assistants, professional advisers, business associates and others who become aware of potential tax non-compliance'

Ian Dickinson, Tax Director at UHY Hacker Young:

'HMRC appears increasingly willing to prosecute individuals who evade tax'

HMRC is looking to close a multi-billion fiscal gap, so it is likely to use all the legal tools it has to recover unpaid tax'

Perspective

The rich and middle-class alike need to be more vigilant regarding their tax affairs.

This new wave of tech-enabled scrutiny, incentivising whistleblowing, and use of legal tools is good news – however – for law and tax firms alike whose advice will be sought by more HNW individuals due to the increasing levels of complexity and likelihood of getting caught if compliance is lacking.
