## What Changed in the UK’s Non-Domiciled Regime
From **6 April 2025**, the UK’s long-standing domicile rules have been **abolished**. Instead, tax liability now depends on **residence**, not domicile. The policies are detailed in the government’s reforms to the taxation of non-UK domiciled individuals.([gov.uk](https://www.gov.uk/government/publications/changes-to-the-taxation-of-non-uk-domiciled-individuals/technical-note-changes-to-the-taxation-of-non-uk-domiciled-individuals?utm_source=openai))
Key changes include:
- The removal of the remittance basis of taxation.
- Introduction of a **4-year foreign income and gains (FIG) regime**: Individuals who become UK tax residents after 10 consecutive years of non-UK residence may benefit from not paying UK tax on foreign income/gains for their first four tax years in residence.([gov.uk](https://www.gov.uk/government/publications/changes-to-the-taxation-of-non-uk-domiciled-individuals/technical-note-changes-to-the-taxation-of-non-uk-domiciled-individuals?utm_source=openai))
- Overseas Workday Relief (OWR) is retained for first 3 years of UK residence, but eligibility is simplified.([gov.uk](https://www.gov.uk/government/publications/changes-to-the-taxation-of-non-uk-domiciled-individuals/technical-note-changes-to-the-taxation-of-non-uk-domiciled-individuals?utm_source=openai))
- Foreign income/gains in trusts are taxed on an arising basis for UK resident settlors or transferors who have been resident for more than 4 years. Pre-6 April 2025 gains have transitional relief via the Temporary Repatriation Facility.([gov.uk](https://www.gov.uk/government/publications/changes-to-the-taxation-of-non-uk-domiciled-individuals/technical-note-changes-to-the-taxation-of-non-uk-domiciled-individuals?utm_source=openai))
## Who Is Affected
- Individuals who **move to the UK** after long periods overseas.
- Those who were living outside the UK and return, or have previously benefited from being non-domiciled.
- Trusts and trust beneficiaries whose beneficiaries or settlors are UK tax resident.
## Practical Implications & Examples
| Situation | Before April 2025 | After Reforms |
|---|---|---|
| Moving to the UK after 12 years overseas | Could claim remittance basis indefinitely (excluding certain UK income) | Eligible for FIG regime — first 4 years foreign income/gains exempt; thereafter taxed on arising basis |
| UK resident with foreign trust income | Possibly taxed only when remitted | Trust income arises is taxed if settlor/resident meets duration requirement |
| Returning resident with assets appreciated while abroad | Gains could be sheltered under prior domicile rules | Transitional relief: assets could be rebased to 5 April 2019; pre-2025 FIG taxed via repatriation facility at 12% for certain years |
## Actionable Tips for Individuals & Advisors
**For prospective UK residents:**
- Establish proof of non-UK residence for the prior **10 tax years** asap to qualify for FIG.
- Be mindful of when the 4-year benefit expires — plan withdrawals or transfers before full arising basis applies.
**For those with overseas trusts/assets:**
- Review trust distributions and gains to assess whether arising basis taxation will apply.
- Consider harvesting gains or repatriating before reforms fully bite if feasible.
**For compliance:**
- Record detailed information about previous periods abroad, foreign income/gains, trust interests.
- Clarify whether Overseas Workday Relief applies during first 3 years of residence.
## Broader Lessons from this Shift
- Residence-based systems provide more neutrality, less opportunity for tax arbitrage based on domicile technicalities.
- Transitional provisions (rebasing, temporary facility) are key; failing to act in these windows can lead to higher tax burdens.
- Advice early is invaluable—migration decisions, funding of trusts, and asset transfers should be timed with tax law milestones.
By understanding these reforms thoroughly, individuals and advisors can make strategic decisions to adapt — from structuring foreign income flows to planning abroad-UK transitions.
