Britain's top 100,000 taxpayers footed an average income and capital gains tax bill of £559,000 each in 2021/22.

That was up by 18% from £475,000 in the previous year. They also paid almost a quarter (24.1%) of HMRC's annual tab from this tax, despite accounting for just 0.3% of UK taxpayers, according to a new Freedom of Information request made by Wealth Club to HMRC.

The top 100 taxpayers in the UK collectively paid a total of £4.6 billion of income and capital gains tax in 2021/22, the equivalent of £46 million each. This is a 14% increase from the £3.9 billion paid in the year before.

Alex Davies, founder of high-net-worth investment service, Wealth Club, said:

"It is commonly claimed that wealthy individuals do not pay their fair share of tax. These figures prove what a myth that is. In fact, 100,000 people paid £55 billion in tax, a staggering 24% of all income and capital gains receipts, despite making up just 0.3% of taxpayers.

"The overall income and capital gains tax take they are paying has risen by 45% in just five years, meaning not only are they paying more, but they are shouldering more of the increasingly heavy burden.

"Meanwhile the top 100 people in the UK paid on average over £46 million each in tax, contributing 2% of the UK's total income and capital gains tax receipts, despite accounting for just 0.0003% of the income and capital gains tax paying population.

"An estimated 3,200 millionaires are expected to leave the UK this year. If the top 100 taxpayers up sticks and move to sunnier tax climates, that would be £4.6 billion less in tax receipts. If the top 1,000 taxpayers migrated out of the UK, that figure would rise to £11.5 billion, leaving a massive gap in the country's finances."

The total income and capital gains tax paid by all UK taxpayers in 2021/22 was £232.7bn. This was paid by a total of 33.3m taxpayers.
