On Tuesday, Zero Hedge posted an article about the number of high-paying taxpayers who have left Britain since 2025 when the non-dom regime was scrapped in April 2025 and inheritance tax was extended to worldwide assets.
The article reports:
This shift is already visible on the Sunday Times lists: six of the 2026 Tax List’s top 100 (including Revolut’s Nik Storonsky) had left in the previous year, the compiler noted that one in nine names on that list were no longer UK-resident, and the companion Rich List dropped dozens of foreign billionaires while recording a sharp rise in British nationals now based in Dubai, Switzerland and Monaco.
But, the latest news is likely the most disturbing to the increasingly socialist government as the UK’s 3rd largest taxpayer – hedge fund founder Chris Rokos – is set to leave.
When you raise taxes to the point where they are confiscatory, people take measures to avoid them. We have seen that in America with the population movement from blue to red states where the taxes and cost of living are lower.
The article notes:
Rokos will also open an office in Athens as part of the move, one of the people said, asking not to be identified because the details are private.
Italy operates a similar 15-year system, but after recent increases, it has set the flat tax at €300,000 on foreign-sourced income.
Greece has also sought to lure fund managers and private equity executives, adopting new tax rules this summer designed to prevent double taxation.
If the highest taxpayers keep leaving – as Rokos’s reported move to Greece underlines – Labour’s bet that abolishing non-doms and tightening inheritance tax would raise more money starts to look fragile, because a thin slice of people already supplies a large share of income-tax receipts.
The government then faces an awkward choice: accept a smaller tax base and tighter budgets, or raise rates on the mobile and immobile alike and risk accelerating the outflow it is trying to tax.
This is the Laffer Curve at work. If you are not familiar with the Laffer Curve, this article at investopedia is a good place to learn about it.
