The number of non-domiciled taxpayers in the UK climbed 7% in 2023 and they paid £8.9bn in tax, according to the latest HMRC figures for 2023.

Some 12,900 non-domiciled taxpayers arrived in the UK in the 2023 tax year, up 18% on the previous year, according to the figures.

HMRC reckons there were 74,000 non-domiciled taxpayers in the UK in 2023, an increase of 7% year-on-year.

Tax revenue from non-domiciled taxpayers in the year came in at £8.9bn, some 6% higher year-on-year, and the highest level since 2017.

The amount non-doms paid includes an estimated £6.2bn of income tax, £384m of capital gains tax and £2.3bn of national insurance contributions.

Nicholas Hyett, investment manager at broker Wealth Club, said: “Non-doms will soon be extinct in the UK, with the new government looking to abolish the tax status that many wealthy individuals use to shelter their international earnings from UK tax. These numbers are therefore a glimpse into the past, soon to be part of the fossil record.”

He pointed out that the Labour manifesto promised a process of evolution with, “a modern scheme for people genuinely in the country for a short period”.

My Hyett said: “These numbers show how important it is to get that new regime right. £8.9bn of tax revenue is not to be sniffed at, and while taxing the rich might raise more revenue it also runs the risk that the global elite decide to move their taxable wealth somewhere with a lighter touch tax regime.”

He said the government must deliver an economic climate that’s more welcoming and more reliable than the British summer has proven this year.

He said: “If it can achieve that it has the potential to achieve the best of all worlds – a tax regime where the wealthy contribute more, but don’t feel the need to flee abroad to sunnier climes.”
