United Kingdom

The baseline you are leaving: worldwide taxation for anyone resident more than four years, a 45% top income rate, dividends at up to 39.35% and gains at 24%. Non-dom status and the remittance basis ended on 6 April 2025, so long-standing residents now pay UK tax on everything they earn anywhere. Leaving does not cut every tie at once: inheritance tax follows long-term residents for 3 to 10 years after departure, and gains made while temporarily non-resident can be pulled back if you return within 5 years.
