The changes to the UK’s Non-Domiciled
The changes to the UK's Non-Domiciled (Non-Dom) tax rules in 2026 mark one of the most significant shifts in the country's approach to international taxation in recent years.
From April 2026, the long-standing remittance basis will be replaced with a simpler, time-limited regime for new arrivals, alongside stricter requirements for long-term residents.
Key highlights include:
- Four-Year Exemption for New Arrivals
Individuals who become UK tax resident will only be able to benefit from a four-year exemption on foreign income and gains, after which worldwide taxation will apply.
- End of the Traditional Non-Dom Status
The concept of indefinite Non-Dom treatment will effectively cease. Longer term residents will face UK tax on global income and gains, with limited transitional reliefs.
- New Planning Considerations
Trusts, overseas structures, and remittance planning will all require review to ensure compliance and efficiency under the new framework.
These reforms are expected to influence where globally mobile professionals choose to live and invest, while also driving significant pre-2026 planning activity.
If you are a Non-Dom or advise international clients, now is the time to review structures and ensure you are prepared for the upcoming changes.
