Recommendation (the committee's words)
HMRC was unable to say what impact the additional revenues it expects to bring in would have on the tax gap. It said it is not practical to set a target for the tax gap as it is measured more than a year after the end of the tax year and is then subject to revisions as more data become available. Instead, HMRC said its operational target was an annual target for compliance yield which, if delivered, should in turn reduce the tax gap, once that is also measured. 60 HMRC said this operational target for compliance yield, set at £45.5 billion for 2024–25, is stretching but that it hopes to achieve it.61

Treasury minutes: Government response to the Committee of Public Accounts on the Third report from Session 2024-25
Published 6 May 2025.
Summary written by Accountability Index from the government's response. It is not the government's own words.The government agrees with most of the Committee's recommendations, with target implementation dates ranging from March 2026 to March 2028 for several, but disagrees with reinstating a call waiting time target and with the proposed resourcing "guard rails" and corrective trigger.
- On a call waiting time target, the government "disagrees". It says ASA "remains a key performance metric" and that its Adviser Attempts Handled measure and customer satisfaction metrics give "a more rounded view" of the experience for all callers.
- The government agrees that call waiting estimates, no cut-offs without warning and a callback service should be required in a new telephone service, with a target implementation date of March 2027. It says the new Contact Service platform procurement will launch in spring 2025.
- The government disagrees with setting a trigger when service levels fall more than five percentage points below target. It says HMRC is "always reviewing plans and forecasts of demand" and adjusting resourcing "day-by-day and week-by-week".
- On tax debt, the government agrees, and HMRC "will respond to the Committee in September 2025" with its expectations for the debt balance by 2029-30 and plans for older debts, allowing for the outcome of Spending Review Phase 2.
