HMRC is one of the largest and most complex organisations in the UK, operating across multiple tax regimes with hundreds of legacy systems.

HMRC are exploring how they can better understand, manage, and reuse their data estate to support efficient transformation, reduce risk, and improve decision‑making across the organisation. They are seeking supplier perspectives on approaches that could help address the following broad challenges:

  • Discoverability and Reuse of Data
  • Traceability and Impact Awareness
  • Efficiency of Transformation Delivery
  • Managing a Complex Legacy Environment
  • Assurance, Compliance, and Risk Management

The procurement

HMRC currently operates Informatica Enterprise Data Catalogue (EDC) and AXON (on-premise solution) to support metadata management and governance activities.

The current contract is planned to be extended to December 2027. Therefore, this provides a natural and time critical opportunity to reassess whether these tools continue to meet HMRC’s strategic objectives. The current tools have the following constraints:

  • Limited scalability and integration with modern cloud platforms.
  • Lack of AI-native capabilities e.g. automated metadata extraction or inference.
  • No knowledge graph engine to connect people, processes, systems, policies, data, and controls.
  • High manual effort required to capture metadata.
  • Fragmented metadata landscape due to inconsistent use across HMRC.
  • Insufficient semantic modelling for complex tax regimes.
  • Limited support for RAG, LLMs, or AI assurance tools.

HMRC want to engage with the market and run a competitive procurement to secure a solution that fully aligns with HMRC’s future operating model and unlocks enterprise value across policy, transformation, assurance, and operations.
