We asked HM Treasury and HMRC what lessons they had learned that could be used in the event of the next emergency, and what they would do differently in future. They identified successes they would like to preserve, in particular, they said there had been effective close working between policy and operational staff and they had put in place a coherent end-to-end compliance approach. They also identified the need for better data to facilitate targeting of support, learning from international experience and improving how they communicated with those taxpayers selected for compliance checks.48
