HMRC, the UK's tax authority, is rolling out Microsoft Copilot to approximately 28,000 staff, moving the AI assistant from experimental use to core infrastructure. This follows a Whitehall trial where civil servants reported saving an average of 26 minutes per day, though the trial also warned that generative AI is weaker on complex, data-heavy work. For an agency handling sensitive citizen and business records, the key challenge is governing AI effectively to match its ambition. Discussions on WindowsForum cover the implications of this rollout, including agentic AI features and governance concerns.
