Wealthy flee as tax raids take their toll Thousands of wealthy people have left Britain in the last five years, with experts saying this comes amid a surge in inheritance tax bills and repeated raids by chancellors. The UK has lost 12,000 rich people since 2017, according to research by migration consultancy Henley & Partners and data firm New World Wealth. It is estimated that 1,500 wealthy individuals – those with assets and cash of more than $1m - are expected to leave the UK this year. Experts point to rising taxes among the factors that are driving departures. Andrew Amoils, head of research at New World Wealth, said an end to loopholes and high taxes, including on inheritance, have contributed. There are only 270,000 people who pay 45% tax and they contribute one third of all income tax, so the loss of wealthy tax payers has a big impact on the overall tax take.
