HMRC has signed a 10-year, £175m contract with British AI firm Quantexa to help tackle tax fraud, fix errors, and improve customer service by combining HMRC data with external sources. The deal comes amid rising public dissatisfaction with HMRC, with complaints exceeding 93,000 in 2024–25, partly due to poor response times. Quantexa has emphasised that AI-driven decisions will remain transparent and human-checked, and that HMRC data will be kept secure within the department's own environment.
