Recommendations & Conclusions

22 items
2 Recommendation 3rd Report - HMRC Customer Service and… Rejected

Allocate sufficient resources to HMRC customer service and establish service level guard rails.

HMRC’s digital services have not sufficiently reduced demand on the phone and HMRC has failed to prioritise the resources needed to sustain an appropriate standard of telephone service. HMRC has been working to become a ‘digital-first’ organisation since 2010 and hopes to replace traditional forms of contact with digital services. …

Government response. The government rejects the recommendation, stating it already proactively reviews and adjusts resourcing levels daily and weekly, and continuously discusses performance and resource needs with HM Treasury and ministers.
HM Treasury
3 Conclusion 3rd Report - HMRC Customer Service and… Accepted

Understand digital service replacement capacity and ensure minimum telephone service for all customers.

HMRC has been too willing to let its telephone services fail in the hope this forces people to use its digital services instead. HMRC estimates 66% of calls it receives could be handled online instead. It hopes that by encouraging customers to use digital services it can free up its …

Government response. The government states it has expanded Extra Support teams and funded community organisations, and will publish a Transformation Roadmap in 2025 outlining plans to extend digital services, ensure digital inclusion, and support customers who cannot interact digitally.
HM Treasury
4 Conclusion 3rd Report - HMRC Customer Service and… Acknowledged

Prioritise introducing systems for customers to submit files and send secure digital messages.

HMRC does not provide an efficient means for taxpayers to communicate digitally with HMRC. In 2022–23, HMRC received 22 million items of correspondence, including physical post and forms and interactive forms. Approximately 70% of this comes in through the post. Postal correspondence, as well as some electronic correspondence, requires scanning, …

Government response. The government agrees with the recommendation to prioritise secure digital communication channels as part of its digital roadmap, affirming this will improve customer service and increase yield.
HM Treasury
5 Recommendation 3rd Report - HMRC Customer Service and… Accepted

Set out debt balance reduction targets and a plan for recovering older uncollectable debts.

HMRC’s investment in debt management has not sufficiently reduced the amount of tax owed to it. In 2023–24, the government announced £303 million additional funding for HMRC to improve its capacity to manage tax debts. This followed £47.2 million announced in 2022–23. Despite this investment, the tax debt balance fell …

Government response. The government commits to responding to the Committee by September 2025, outlining its expectations for the tax debt balance by 2029-30 and plans for recovering older debts.
HM Treasury
6 Conclusion 3rd Report - HMRC Customer Service and… Accepted

Set ambitious targets for tax gap reduction, develop offshore strategy, and research effective deterrents.

We welcome HMRC’s new goal to reduce the tax gap but we are concerned that it still plans to reduce the number of prosecutions. HMRC expects to bring in £6.5 billion additional tax revenue by 2029–30 as a result of measures set out at the Autumn Budget 2024, and has …

Government response. The government agrees with the recommendation, stating it will increase counter-fraud capability and publish an updated Issue Brief detailing its ambitions to address fraud and its increased effectiveness through civil and criminal powers, also committing to publish a target for …
HM Treasury
1 Conclusion 3rd Report - HMRC Customer Service and… Accepted

Committee takes evidence from HMRC on 2023-24 performance and customer service.

On the basis of a report by the Comptroller and Auditor General, we took evidence from HM Revenue & Customs (HMRC) on its performance in 2023– 24 and its customer service.1

Government response. The government states it is actively exploring the use of callbacks and will launch procurement for a new Contact Service platform in spring 2025, aiming for it to be in place by 2026-27.
HM Treasury
7 Recommendation 3rd Report - HMRC Customer Service and… Accepted

HMRC provides limited and delayed information on customer telephone waiting times.

We asked whether HMRC provides customers with information on expected call waiting times. It said it provides this information on many of its helplines, but the information is limited to the average call waiting time from the previous day rather than a current waiting time. HMRC explained this was another …

Government response. HMRC will procure a new Contact Service platform in Spring 2025 to be in place in 2026-27, that gives customers an indication of likely wait time and call back options.
HM Treasury
8 Conclusion 3rd Report - HMRC Customer Service and… Accepted

HMRC continues receiving millions of calls despite digital-first ambition and roadmap plans.

HMRC has been working to become a ‘digital-first’ organisation since 2010 and hopes to replace traditional forms of contact with digital services.13 It said its research shows that 86% of customers say they are willing to deal with HMRC digitally or would prefer to do so.14 Despite this, HMRC still …

Government response. The government agreed with the committee's recommendation to consider HMRC's resourcing as part of the Spending Review to further digitise customer services and enable more customers to self-serve online, and will publish a Transformation Roadmap in 2025 outlining plans to …
HM Treasury
9 Conclusion 3rd Report - HMRC Customer Service and… Rejected

HMRC faces resource shortages as taxpayer numbers and complexity continue to increase.

HMRC says it has not had enough resources to deal with all the contact it has been receiving.17 It estimates that in the last two years, the number of taxpayers in the income tax system has increased by 3 million as a result of the freezing of income tax thresholds. …

Government response. The government disagrees with the conclusion that HMRC has been too willing to let its telephone services fail and states that improving customer services is one of the Exchequer Secretary to the Treasury's priorities. It says it will publish a …

10 Conclusion 3rd Report - HMRC Customer Service and… Accepted

HMRC secured additional funding for staff, achieving telephone customer service targets in 2024.

In May 2024, HMRC received £51 million additional funding, to cover approximately 1,500 staff for 2024–25, to bring its customer service to target levels for answering 85% of customers’ attempts to speak to an adviser on the telephone and for handling 80% of correspondence within 15 working days.19 It said …

Government response. The government agreed with the committee's recommendation to consider HMRC's resourcing as part of the Spending Review to further digitise customer services and enable more customers to self-serve online, and will publish a Transformation Roadmap in 2025 outlining plans to …
HM Treasury
11 Conclusion 3rd Report - HMRC Customer Service and… Accepted

HMRC digital service usage and customer satisfaction have significantly increased since 2015.

HMRC said that approximately 70% of interactions with it are digital.21 Since 2015, it has introduced several digital services, including Personal and Business Tax Accounts, an app, and its flagship Making Tax Digital programme for VAT.22 In 2022–23, customers accessed online Personal and Business Tax Accounts and the HMRC app …

12 Recommendation 3rd Report - HMRC Customer Service and… Acknowledged

Many calls could be digital, yet some services remain offline and customers need assistance.

While the use of digital services has increased, HMRC still estimates that 66% of telephone calls could have been handled online. HMRC said this partly reflects customer awareness of the extent of its digital services. It started a campaign in November 2024 to increase awareness, particularly of its mobile app.26 …

Government response. HMRC is considering resourcing as part of the Spending Review, further digitizing customer services, and will publish a Transformation Roadmap in 2025 outlining plans to extend digital services and provide better customer service, including measures for digital inclusion and support.
HM Treasury
13 Conclusion 3rd Report - HMRC Customer Service and… Rejected

HMRC reversed controversial helpline closures following public criticism, with no further plans.

HMRC closed or reduced the queries it handles on four helplines in 2023–24. For the largest change, the trial closure of the Self Assessment helpline in summer 2023, it gave customers only two working days’ notice.31 HMRC said it was not entirely clear what customers would have gained from having …

Government response. The government disagrees with the conclusion that HMRC has been too willing to let its telephone services fail and states that improving customer services is one of the Exchequer Secretary to the Treasury's priorities. It says it will publish a …
HM Treasury
14 Conclusion 3rd Report - HMRC Customer Service and…

HMRC consistently fails to meet targets for processing high volumes of postal correspondence.

HMRC received 22 million items of correspondence in 2022–23, including physical post and forms and interactive forms.37 Around 70% of correspondence comes in through the post. To process postal correspondence, as well as some electronic correspondence, HMRC must scan or manually enter the information into its systems, or both.38 HMRC …

HM Treasury
15 Recommendation 3rd Report - HMRC Customer Service and… Acknowledged

HMRC lags in secure digital file sharing; plans secure messaging via app and tax accounts.

HMRC said it uses email sparingly due to security concerns.42 Several organisations representing taxpayers and their agents wrote to us to highlight the need for a secure digital way to share files and correspondence with HMRC so that communication by post and phone became the exception.43 HMRC acknowledged that it …

Government response. HMRC is considering options to enhance and improve its current services to give taxpayers and intermediaries secure digital channels for communication and document exchange.
HM Treasury
16 Conclusion 3rd Report - HMRC Customer Service and… Deferred

HMRC's tax debt remains stubbornly high at £43 billion, significantly above pre-pandemic levels.

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 …

HM Treasury
17 Recommendation 3rd Report - HMRC Customer Service and… Deferred

High levels of new tax debt continue, prompting HMRC to secure funding for more staff.

HMRC said it is still seeing very high levels of new debt coming into the system, largely as a result of cash-flow issues in small businesses.49 In the Autumn Budget 2024 it received funding for a further 1,800 debt management staff. This follows an additional £303 million in 2023–24 and …

Government response. HMRC will respond in September 2025 with its expectations for the tax debt balance by 2029-30 and plans for older debts, allowing for the outcome of the Spending Review Phase 2 to be taken into consideration. They also mention increased …

18 Recommendation 3rd Report - HMRC Customer Service and… Deferred

Older HMRC debts are less likely to be repaid, requiring tailored interventions.

As HMRC’s debts get older, they are less likely to be repaid.52 HMRC stressed the importance of tackling the new debt before it ages.53 We asked whether HMRC has a new approach planned for tackling older debts.54 It said it 47 Report on 2023–24 Accounts, para 7 48 Qq 37-38 …

19 Conclusion 3rd Report - HMRC Customer Service and… Accepted

HMRC's tax gap increased to £39.8 billion, driven significantly by small business non-compliance.

HMRC estimates that the tax gap–the difference between the amount of tax that should be paid to HMRC, and what was actually paid–increased from £38.1 billion in 2021–22 to £39.8 billion in 2022–23 (the latest year for which HMRC has made an estimate). As a proportion of tax due, it …

HM Treasury
20 Recommendation 3rd Report - HMRC Customer Service and… Accepted

HMRC unable to quantify the direct impact of additional revenues on the total tax gap.

21 Recommendation 3rd Report - HMRC Customer Service and… Acknowledged

HMRC's tax gap estimations, particularly for offshore and foreign income, remain uncertain.

HMRC said that its calculation of the tax gap uses estimation and judgement, and that some parts of it are more certain than others.62 It said in October 2024 it published experimental statistics on the proportion of the tax gap that comes from foreign income. In monetary terms, HMRC 55 …

Government response. HMRC will assess the feasibility of extending the published estimate of the tax gap arising from undisclosed foreign income, including engaging with academics and scaling up compliance activity.

22 Recommendation 3rd Report - HMRC Customer Service and… Accepted

Significant decline in criminal tax prosecutions risks reducing the deterrent effect on non-compliance.

In 2023–24 there were 344 criminal prosecutions, compared with 691 in 2019–20, before the pandemic.64 HMRC said it is very successful in its criminal investigations and has a high conviction rate in its prosecutions, but that it tends to reserve their use for the most serious and higher- value cases …

Government response. HMRC will increase counter-fraud capability and expand work to address fraud, publishing an updated Issue Brief articulating its ambitions and areas of likely focus, and considering the associated uplift in positive charging decisions.
