A £175 million deal aims to improve efficiency and tackle fraud in the UK tax system
Category: Business
In a landmark move, HM Revenue and Customs (HMRC) has signed a £175 million contract with Quantexa, a London-based software firm, to modernize its data infrastructure and implement advanced artificial intelligence (AI) systems. This 10-year partnership is part of HMRC's broader strategy to streamline operations, improve taxpayer services, and combat organized tax crime, marking one of the UK's largest AI deployments in the public sector.
The announcement of the contract comes as HMRC intensifies its efforts to integrate AI and automation technologies across the department. Last month, HMRC confirmed it was rolling out 29,000 Microsoft Copilot licenses, aiming to embed AI into daily operations. James Mitton, HMRC’s chief AI officer, has expressed ambitions to transform the agency into the "world’s most AI-enabled tax authority." This partnership with Quantexa is expected to significantly advance these goals.
Quantexa specializes in "decision intelligence" technology, which combines AI, analytics, and contextual data modeling to identify risks and inefficiencies within large datasets. The technology will enable HMRC to connect siloed data sources, unearthing hidden relationships and supporting informed decision-making in areas such as fraud detection, compliance, and customer service. By using graph analytics and entity resolution, the tax office will be able to link IP addresses and device fingerprints to dismantle synthetic identities and mule networks associated with cyber-enabled fraud.
This initiative is particularly timely, as HMRC has faced increasing public scrutiny over its performance. Complaints about the agency rose to over 93,000 in 2024-25, up from 70,000 four years earlier, with response times cited as a primary concern. The integration of AI is seen as a way to improve service delivery and operational efficiency, allowing HMRC to focus its resources where they are most needed. As AI Minister Kanishka Narayan stated, "This partnership will help HMRC deploy AI safely at scale, bringing its data together to support smarter decisions, improve efficiency, and deliver a stronger service for taxpayers."
The HMRC-Quantexa collaboration also reflects a growing emphasis on digital sovereignty within the UK government, as it seeks to reduce reliance on foreign technology platforms for sensitive operations. By partnering with a British firm, HMRC aims to maintain control over its data and decision-making processes. As part of this strategy, Microsoft is also rolling out its 365 Copilot and Gen AI agents to HMRC staff, with plans to extend access to 50,000 employees. This dual approach enhances operational capabilities and reinforces the importance of human oversight in AI-driven processes. Quantexa CEO Vishal Marria emphasized that the technology is built to support human decision-making, stating, "In government environments, AI cannot operate as a black box." Every automated insight must remain transparent and auditable, ensuring that human experts review decisions.
As HMRC embarks on this ambitious transformation, it aims to create a more resilient and proactive digital-first service. By automating low-level clerical tasks, the agency intends to free its specialist investigators to focus on high-value, complex cyber-crime cases. If successful, this initiative could serve as a blueprint for how large-scale government departments can leverage AI to combat sophisticated fraud schemes and improve public service delivery.
With this £175 million investment in AI and data modernization, HMRC is not just addressing current inefficiencies but is also setting the stage for a future where technology plays a central role in tax administration. The success of this program will be closely monitored, as it has the potential to significantly impact the taxpayer experience and the efficiency of public services across the UK.
As the rollout progresses, stakeholders will follow closely closely to see how these technologies are integrated and how they improve both operational performance and customer service. The upcoming months will be telling, as HMRC strives to balance innovation with accountability, ensuring that the implementation of AI enhances rather than undermines public trust in the tax authority.
