Moving Abroad & UK Inheritance Tax: What Many Business Owners Miss
Does Moving Abroad Stop UK Inheritance Tax? – It’s Not as Simple as Many Business Owners Think
One of the most common assumptions in succession and wealth planning is simple:
“If I move abroad, UK inheritance tax no longer applies.”
For many internationally mobile business owners, the perceived solution is often a move to jurisdictions such as Dubai or Monaco.
In short — it is usually not that simple.
In some cases, individuals can remain exposed to UK inheritance tax for up to 10 years after leaving the UK.
Recent reforms mean that, depending on an individual’s UK residence history, moving abroad may not help to reduce UK inheritance tax (IHT) exposure at all — and in some cases, individuals can remain within the UK IHT regime for many years after departure.
Despite the significance of the changes, many business owners and advisers remain unaware of how the new rules operate in practice.
What Many People Assume — And What The Rules Actually Mean
Common assumption:
“If I move to Dubai and become non-UK resident, UK inheritance tax no longer applies.”
Practical reality:
For many long-term UK residents, UK inheritance tax exposure can continue for years after departure, potentially extending to worldwide assets, depending on residence history.
Simply changing location or tax residence may therefore not achieve the inheritance tax outcome many individuals expect.
What Changed – IHT is Now Increasingly Based On Residence
From 6 April 2025, the UK moved away from the traditional domicile-based approach for inheritance tax and introduced a new long-term residence regime.
Broadly speaking, an individual may now fall within the UK IHT net if they have been a UK tax resident for at least 10 of the previous 20 tax years, i.e. you may remain exposed to IHT for a full decade after you left the UK.
Under the new rules, individuals can remain within the UK inheritance tax regime for a continuing “tail period” after departure, depending on how long they previously lived in the UK.
For some individuals this may be:
3 years after leaving
5 years or more for longer-term residents
up to 10 years after departure for those with extensive UK residence history
In practical terms, this means that many business owners who have spent significant time living and building wealth in the UK may continue to be exposed to UK inheritance tax long after relocating overseas.
Example – Business Owner Relocating To Dubai
A business owner sells their company and subsequently relocates to Dubai.
Common assumption
"The UK inheritance tax issue has now gone away."
Practical reality
Depending on residence history and the new long-term residence rules, UK inheritance tax exposure may continue for many years after departure, potentially applying to the business sale proceeds and wider family wealth.
In practical terms, an individual who has lived in the UK for 10 years may still find themselves within the UK inheritance tax regime for up to a further 10 years after leaving.
Why This Matters For Business Owners
For SME owners and entrepreneurial families, these changes are particularly relevant where wealth comprises:
trading company shareholdings
business sale proceeds
pension wealth
overseas property or investment holdings
trusts and family succession structures
This can be particularly relevant where wealth has already been crystallised through a business sale, investment portfolio, property holding or pension accumulation. Simply relocating overseas may not remove UK inheritance tax exposure from those assets as quickly as many expect.
Professional commentary has described the move to residence-based inheritance tax as “the most significant change to UK inheritance tax in decades”, reflecting its broad implications for internationally mobile individuals and families.
Pensions and Cross-border Planning Considerations
These changes also sit alongside the planned April 2027 pension reforms, under which unused pension funds and certain death benefits are expected to fall within the inheritance tax net.
For internationally mobile business owners and families, this may create additional complexity across:
pensions
estates
overseas succession regimes
family wealth structures
There may also be circumstances where beneficiaries face multiple layers of taxation, including inheritance tax, income tax and overseas succession taxes.
Financial advisory firm deVere Group has estimated that approximately 4.8 million Britons living overseas could potentially still be affected by UK inheritance tax exposure under the revised rules.
Practical Implications For Business Owners and Advisers
These developments reinforce several important planning considerations:
moving abroad is not, in itself, an inheritance tax strategy
residence history matters — often significantly more than expected
succession planning should be reviewed before relocation, not afterwards
cross-border wealth structures require careful technical review
pension, trust and business ownership arrangements may require reassessment under the new regime
In many cases, the timing of planning can be critical. Reviewing structures before relocation may provide materially different options compared to addressing the position after departure.
As with many recent tax reforms, planning opportunities remain available — but timing, structure and technical detail are becoming increasingly important.
