AUTUMN BUDGET 2024 – A BOON FOR LONG TERM EXPATS?
Introduction

However, there has been less discussion about how these changes will affect individuals with a UK background, particularly British ex-pats.
The proposed changes, set to come into effect on 6 April 2025, present opportunities for British ex-pats living around the world.
While some technical details could still evolve, the draft legislation released on 30 October provides clarity on the framework. This note explores the implications for British ex-pats under the new regime.
Key Features of the New Regime for British Ex-Pats (Effective 6 April 2025)
Special Four-Year Tax Regime for Returning Residents
Qualifying individuals will be exempt from UK tax on their foreign income and gains for their first four years of residence, regardless of whether such income is remitted to the UK.
Eligibility applies to anyone who becomes UK resident after at least ten tax years of non-UK residence, irrespective of their domicile.
New Residence-Based Test for Inheritance Tax (IHT)
Domicile will no longer determine liability for IHT. Instead, individuals will be subject to IHT on worldwide assets after being UK resident for 10 out of the previous 20 tax years.
If they subsequently leave the UK, their estates will remain subject to IHT for a “tail period” of 3–10 years, depending on their duration of UK residence.
Favourable Transitional Rules for Current Non-Residents
Individuals who are non-UK resident during the current tax year and were not UK domiciled on 30 October 2024 can benefit from transitional provisions that shorten the IHT “tail.”
Planning Points for British Ex-Pats
Returning to the UK
Under the current regime, individuals born in the UK with a UK domicile of origin are immediately deemed UK domiciled upon becoming UK resident, making their worldwide income and gains subject to UK tax.
The new rules change this dynamic:
- Those returning to the UK after ten years of absence can take advantage of the special four-year tax regime, exempting non-UK income and gains from tax.
- This presents a favourable window for British ex-pats to return temporarily—for example, to care for elderly parents, settle children in UK schools, or manage tax planning in another jurisdiction.
The UK’s statutory residence test, while complex, offers clear guidance on residence status, enabling individuals to determine their first year of residence and plan their eventual departure if desired.
Increased Certainty Around IHT
The current system ties IHT liability to domicile, which can be difficult for globally mobile individuals to establish. Even after decades of living abroad, a UK domicile of origin can persist if the individual has not formed a permanent intention to remain elsewhere.
The new residence-based IHT test provides clarity:
- Individuals who have been non-UK resident for 10 years by 6 April 2025 can benefit from the change immediately, gaining certainty over the IHT treatment of their non-UK assets.
- Those non-UK resident for less than 10 years by that date will face transitional uncertainty, as the new rules apply only to those with a non-UK domicile on 30 October 2024.
Opportunities to Create Trusts and Structures
The new IHT regime has significant implications for trust creation and other estate planning structures:
- Under current rules, transferring assets to a trust by a UK-domiciled individual triggers immediate and ongoing IHT liabilities, creating risks for ex-pats with uncertain domicile status.
- From 6 April 2025, certainty around IHT treatment will enable non-UK residents to create trusts and similar structures without the risk of upfront IHT charges, supporting succession planning and asset protection.
However, ongoing IHT risks remain:
- Trusts established outside the scope of IHT may later fall within it if the settlor resumes UK residence and meets the 10/20 residence test. Careful monitoring will be required.
Need for Expert Advice
While the proposed regime simplifies certain aspects of the tax rules, expert advice remains essential for individuals returning to the UK.
The new rules bring potential tax implications for corporate, trust, and other structures, making pre-arrival planning crucial.
It is also important to note that UK-based assets and assets linked to UK residential property will remain within the scope of IHT, regardless of residence status.
Conclusion
The new regime introduces welcome clarity and opportunities for British ex-pats, particularly in terms of temporary UK returns and estate planning.
However, careful planning is necessary to maximise benefits and mitigate risks under the new rules.
