HMRC Awards Quantexa £175 Million Contract for AI Fraud Detection System
HM Revenue and Customs (HMRC) has announced a significant 10-year contract worth £175 million with UK-based tech company Quantexa. The agreement focuses on deploying artificial intelligence (AI) technology to enhance HMRC’s operational efficiency in detecting fraud and correcting unintentional inaccuracies in tax returns.
Quantexa's systems are designed to merge data collected by HMRC with external information sources. This integrated approach will assist customer service personnel and, critically, identify complex networks of individuals and companies involved in fraudulent activities.
Government figures indicate a rise in public complaints regarding HMRC’s performance in recent years. A Freedom of Information request, submitted by the Contentious Tax Group, revealed over 93,000 complaints in the 2024-2025 period, a notable increase from just over 70,000 in 2020-21. Poor response times constituted a primary grievance.
Quantexa has affirmed that any automated decisions made by AI concerning taxpayers will necessitate human oversight. Vishal Marria, Quantexa's chief executive, stated that the technology is intended to "support human decision-making, not replace it," emphasising the need for transparency, auditability, and explainability in government AI applications, especially where citizens are directly affected. Marria also assured that HMRC data would remain secure within the department's environment, with Quantexa staff working on the project operating separately from the company's broader business.
The company, valued at $2.6 billion, lists HSBC and Vodafone among its corporate clients. The selection of a British firm aligns with the government's broader strategy to cultivate "digital sovereignty," addressing concerns over the UK's reliance on US-based big tech platforms and services, such as the controversial £330 million contract awarded to Palantir for an NHS data platform.
