Quantexa to receive £175 million to modernize the UK tax system
UK tax authority HMRC has signed a major 10-year contract worth £175 million with London-based company Quantexa. The company will modernize HMRC's data infrastr
The UK tax authority HMRC announced a partnership with Quantexa, a British company specializing in AI for fraud detection. The £175 million contract for 10 years is one of the largest government AI contracts in British history.
Scale of Investment
£175 million is a serious investment in technology. The contract covers a complete modernization of HMRC's data infrastructure and the implementation of AI systems for automatic detection of fraud and errors in tax declarations. The main goal is to close the tax gap — the difference between expected and actually received taxes. In the UK, this figure amounts to billions of pounds annually.
What Quantexa Will Do
The company will deploy several key artificial intelligence solutions:
- Automatic detection of tax fraud through analysis of behavioral patterns
- Identification of errors in declarations with automatic correction
- Analysis of relationships between companies and individuals to identify evasion schemes
- Risk forecasting based on historical HMRC data
- Integration with existing infrastructure without a complete rewrite of legacy systems
Quantexa was founded in 2016 and specializes in detecting financial fraud and money laundering. The company has already worked with banks and law enforcement agencies, so it has experience working with sensitive data and meets strict government sector security requirements.
A British Alternative to American Solutions
HMRC's choice of Quantexa has an obvious political undertone. Several years ago, the UK spent £900 million on Palantir — an American company known for its close ties to intelligence services. The new solution signals the UK's desire to build its own AI stack and reduce dependence on American technology giants. Investment in a British company is not only an economic move, but also a matter of technological sovereignty.
What This Means
This contract demonstrates that the public sector is ready to invest in AI not for publicity, but to solve concrete economic problems — recovering hundreds of millions in unpaid taxes. The success or failure of this project could become a benchmark for other government agencies considering the implementation of similar fraud detection systems.
