Select committee: Public Accounts Committee

Conclusion 16

3rd Report - HMRC Customer Service and Accounts Published 22 Jan 2025 Addressed to HM Treasury
Conclusion (the committee's words)
The amount of tax debt owed by taxpayers to HMRC fell only marginally in 2023–24, from £43.9 billion at 31 March 2023 to £43.0 billion at 31 March 2024 (5.1% of annual tax revenues). This compares with a debt balance of typically £15 billion in the five years before the pandemic, or 2.5% of tax revenues. HMRC has estimated it may not be able to collect 45% of the established tax liabilities not yet received from taxpayers. In 2023–24, it wrote off £5.0 billion of debt, an increase from £3.2 billion in 2022–23.47 HMRC said that most of its write-offs are when taxpayers become insolvent, and that delays in the courts and a suspension on insolvencies as a result of the pandemic created lower-than-expected levels of write-offs in previous years. It expects write-offs to increase again in 2024–25 as these insolvencies then work through the system.48

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.
