Bloomberg Billionaires Index reveals UK tax impact on billionaires
Summary
Billionaires are leaving the UK in significant numbers due to the introduction of higher taxes on overseas wealth, a trend highlighted by new data from the Bloomberg Billionaires Index. This exodus follows the UK's abolition of the non-dom tax regime in 2025, which replaced it with a residence-based taxation system for foreign income and gains. As a result, many high-net-worth individuals are relocating to lower-tax jurisdictions such as Switzerland, Monaco, and the UAE.
