HMRC does not know how many billionaires pay tax in UK

HM Revenue and Customs (HMRC) cannot identify how much tax is paid by UK billionaires, despite the relatively small number of individuals and significant sums of money involved, according to a report.
The Public Accounts Committee (PAC) said that HMRC 'can and must' do more to understand and explain the contribution that the very wealthiest in society make to tax revenue.
Its report on collecting the right tax from wealthy individuals said: 'HMRC does not know how many billionaires pay tax in the UK or how much they contribute overall.'
It highlighted The Sunday Times Rich List and artificial intelligence (AI) as ways that the revenue body could dig deeper into wealth and assets.
The PAC is calling for the revenue body to publish its plan for increasing tax yield from wealthy taxpayers both domestically and offshore.
It said HMRC does not collect information on taxpayers' wealth and says that it only collects the data needed to administer the tax system as required by UK tax legislation.
The report said: 'There is much public interest in the amount of tax the wealthy pay.
'People need to know everyone pays their fair share.'
HMRC's plan for improving its understanding of the wealth and assets held by billionaires could include how it might immediately start work on comparing available data on known billionaires, such as The Sunday Times Rich List, with its own records, the report suggested.
In the United States, the Inland Revenue Service has worked with researchers to link its data to The Forbes 400, the report said.
There is 'much more' that HMRC can do to improve its work to risk assess and target wealthy people, in particular through the use of data and technology and recruiting wealth management experts, it added.
It said: 'We think there is scope for HMRC to use artificial intelligence (AI) to better exploit and analyse data and, in this way, improve its risk assessment and targeting of wealthy individuals.
'Possible uses of AI to speed up the system include sifting large amounts of data and suggesting what information is missing from tax returns.'
The tax authority told the inquiry that the tax gaps – the difference between taxes theoretically owed and those actually paid – for wealthy people and for offshore wealth are particularly difficult to measure.
Since 2019-20, HMRC defines wealthy individuals as those with incomes of £200,000 or more, or assets equal to or above £2m, in any of the past three years.
The PAC said it is concerned that HMRC is overly confident and optimistic in its estimate that the wealthy tax gap is £1.9bn.
Its partial estimate of the offshore tax gap, of £0.3bn, seems far too low, particularly when compared with UK residents holding £849bn in offshore accounts in 2019, the committee said.
PAC member Lloyd Hatton said: 'This report is not concerned with political debate around the redistribution of wealth.
'Our committee's role is to help HMRC do its job properly ensuring wealthy people pay the correct tax.
'While HMRC does deserve some great credit for securing billions more in the tax take from the wealthiest in recent years, there is still a very long way to go before we can reach a true accounting of what is owed.
'We already know a great deal about billionaires living in the UK, with much information about their tax affairs and wealth in the public domain.
'So we were disappointed to find that HMRC, of all organisations, was unable to provide any insight into their tax affairs from its own data – particularly given that any single one of these individuals' contributions could make a significant difference to the overall picture.
'We found a similar apparent lack of curiosity in how wide the tax gap is both for the very wealthy and for wealth stashed away offshore.
'Our report shows that, however you slice it, there is a lot of money being left on the table.
'HMRC must, under its new leadership, begin collecting the correct amount of tax from the very wealthiest – and this must include wealth that is currently squirrelled away in tax havens.
'There is certainly room for improvement.'
The yield from HMRC's compliance work with wealthy individuals has more than doubled in recent years, with it collecting £5.2bn in 2023-24, up from £2.2bn in 2019-20.
But the report said: 'The scale of this success suggests either non-compliance among the wealthy has got worse, or that previous estimates of the extent to which they were avoiding tax were too low.'
HMRC has identified opportunities that will help it close the tax gap.
There are currently around 1,000 people in the wealthy team, and HMRC has secured funding for another 400 staff, the report said.
The population of wealthy taxpayers that HMRC's wealthy team administers is growing, up from 700,000 individuals in 2019-20 to 850,000 individuals in 2023-24, it added.
HMRC treats wealthy people as one single group and says it finds some billionaires have quite straightforward tax planning, while some millionaires with much lower wealth will have set up very complex offshore trusts and structures, the committee said.
The revenue body deploys customer compliance managers according to taxpayers who pose the most risk and says managers typically end up working on cases relating to individuals with wealth above £10m, it added.
The committee recommended that HMRC should review whether segmenting its wealthy customer group according to different levels of wealth and complexity would help it to assess and then target the most significant risks.
HMRC should also write to the committee to explain how confirmed funding to date will feed through to better compliance performance, and what it expects to achieve from future investment, the committee said.
It added that a lack of penalties issued to enablers of tax evasion is 'particularly disappointing' despite unscrupulous advisers often playing a key role in helping the wealthy evade tax.
HMRC should assess whether it is using its powers to tackle non-compliance by the wealthy sufficiently, in particular, whether it makes enough use of available sanctions, the report said.
