ÌìÃÀÓ°Ôº

Our priorities are to close the tax gap, improve day to day performance and the overall customer experience and modernise tax and customs administration. These are now enshrined as part of our new strategic objectives, which you can read about in our latest HMRC annual report and accounts. We are working on further measures across all of our strategic objectives, that may be added to this publication at a later date.

This publication shows how we are performing, with some measures updated on a monthly basis and some quarterly.

Close the tax gap

Our lead measures for this priority are the tax gap and compliance yield. In 2023 to 2024, the tax gap was:

Maintaining the long-term reduction from 7.4% in 2005 to 2006. The absolute value was £46.8 billion [note 1].

The compliance yield we brought in during quarter 1 was:

Note 1: The tax gap is the difference between the amount of tax that should, in theory, be paid to HMRC, and what is actually paid. For the latest tax gap statistics, please see Measuring tax gaps 2025 edition: tax gap estimates for 2023 to 2024.

Our compliance work

Each year, we collect and protect billions of pounds of revenue that would have been lost to the Exchequer without our interventions. Our compliance work helps to keep the tax gap low.

Key Performance Indicators	Q1	Year to date	Target
Total compliance yield (£ million)	9,033.0	9,033.0	50,400

Compliance yield breakdown	Q1	Year to date

Criminal sentences — custodial (years)	27.8	27.8

Closed criminal investigations	95	95

Debt

We want to collect more of the tax that is due, whilst supporting customers who are in financial difficulty to manage their way out of debt with our flexible Time to Pay arrangements. The measures below show the trends on various debt measures. Our lead metric for debt is the tax debt balance as a proportion of tax receipts, which we report in HMRC’s annual report and accounts.

Debt balance and time to pay	Q1
Total debt balance (£ million)	42,592
— of which: managed debt (£ million)	6,512
— of which: debt available for pursuit (£ million)	36,081
Number of customers in time to pay arrangements	870,601

New debt and debt resolved	Q1	Year to date
Value of new debt (£ million)	22,400	22,400
Value of debt resolved (£ million)	24,110	24,110

Reviews and litigation

We know there will be occasions where customers disagree with us on the amount of tax that is due. We seek to resolve any dispute as quickly and cost-effectively as possible, in accordance with the law, using our Litigation and Settlement Strategy and our Code of Governance for resolving tax disputes.

Dispute resolution measures	Q1	Year to date
Number of HMRC reviews concluded (related to automated penalties)	16,960	16,960
— of which: number of HMRC decisions upheld (related to automated penalties)	6,285	6,285
Upheld rate (related to automated penalties)	37.1%	37.1%
Number of HMRC reviews concluded (related to all other matters)	1,476	1,476
— of which: number of HMRC decisions upheld (related to all other matters)	948	948
Upheld rate (related to all other matters)	64.2%	64.2%
HMRC litigation court and tribunal decisions [note 2]	407	407
— of which: HMRC litigation win	346	346
— of which: HMRC litigation part win	9	9
— of which: HMRC litigation loss	52	52
Litigation success rate	87.2%	87.2%

Note 2: Not all litigation cases are finalised through a court judgment. Some are resolved through mutual agreement between the parties involved, without the need for a formal ruling. As a result, the overall volume of cases is higher than the court and tribunal outcomes reported here.

Improve day-to-day performance and the overall customer experience — monthly and quarterly measures

Our lead metrics for this priority are the proportion of customer interactions using automated or digital self-serve channels and the customer satisfaction score.

In quarter 1, the proportion of our customer interactions through automated or digital self serve channels was:

Our overall customer satisfaction score was:

Digital channel adoption

Our digital-first customer service strategy aims to enable as many customers as possible to self-serve online. This frees up our advisers to support those customers who will need to contact us by phone or post — for example, those who are vulnerable, those who struggle to get online or those who have complex queries. The figures below show the progress we’re making.

Digital channel adoption	Q1	Year to date
Customer interactions through automated or digital self-serve channels (% of all customer interactions) [note 3]	76.4%	76.4%
Personal Tax Account — Sessions	37,246,322	37,246,322
Business Tax Account — Sessions	11,741,524	11,741,524
HMRC App — Sessions	41,855,623	41,855,623
HMRC App — New users	758,623	758,623

Note 3: The digital channel self-serve % includes several types of interaction with customers that are not all covered in this publication, such as digital tax return submissions.

Customer experience

We are committed to meeting our customer service standards, including our targets for customer satisfaction and how easy customers find interacting with us.

Customer experience measures – phone, webchat and digital services	Apr	May	Jun	Year to date	Target
Overall customer satisfaction	79.5%	80.0%	81.0%	80.2%	80%
Net easy	+62.5	+63.3	+64.7	+63.5	+65
Once and done	84.5%	85.4%	86.2%	85.4%	Not applicable

Annual customer survey results for:

• ease of dealing with tax issues
• overall experience of dealing with HMRC over the last 12 months
• ease of finding information from HMRC
• HMRC is an organisation I can trust

These measures are recorded annually and are reported in HMRC’s annual report and accounts and our customer survey publications.

Customer experience breakdown by channel

When we break down our customer experience metrics for some of our key channels — phone, webchat and digital — we can see that the increasing number of customers using our online services to manage their tax affairs are generally satisfied with them, find them easy and can do what they need to.

Telephony

A digital self-serve experience remains our ambition for the majority of our customers, but we recognise that this will not be appropriate for all, and that some customers will need a period of adjustment to build familiarity and trust in them, and some customers are unable to use digital services or have complex queries. The measures below show the level of demand for our telephony services, call handling and wait times and how we’ve performed against our telephony target.

Support wider government economic aims through HMRC’s work

HMRC does much more than collect taxes. We support wider government aims, for example, by ensuring that everyone follows the rules and by protecting the system from those who seek to exploit it to gain an unfair advantage.

Protecting society from harm

We monitor performance and report externally:

• the number of workers paid arrears via National Minimum Wage employer checks
• the value of financial penalties issued for non-compliance with money laundering regulations

These metrics are published annually in HMRC’s annual report and accounts.

Proceeds of crime recovery	Q1	Year to date
