The UK Autumn Budget, delivered in November 2025, was one of the most closely watched fiscal statements in years for high-net-worth individuals, British expatriates, non-doms, and international investors. With public finances under pressure and the government openly shifting toward heavier taxation of wealth, capital, and property, many feared that the UK would introduce a formal exit tax on people leaving the country.
That did not happen.
The most important conclusion for globally mobile individuals is clear: The UK has NOT introduced an exit tax on wealthy individuals leaving the country.
This confirmation from both the UK Government and HM Treasury is a major stabilising factor for international mobility, offshore structuring, and long-term expatriate planning.
However, while no formal exit tax now exists, the 2025 Budget still delivered deep structural changes to residency, domicile, trusts and inheritance tax that dramatically affect internationally mobile families.
This article explains what changed, what didn’t, and how this reshapes UK Exit Tax Wealth Planning for expats, non-doms, and global investors.
If you’re unsure how the Budget changes may affect your residency, trusts, or long-term tax exposure, now is the time to seek clarity. Speak with the specialist team at Global Investments to understand your position and plan your next steps with confidence.
UK Exit Tax Wealth Planning: Has the Government Introduced a Tax on Leaving the UK?
In the months leading up to the Budget, speculation about a UK exit tax reached fever pitch. Several European jurisdictions already impose wealth departure taxes on individuals when they emigrate, crystallising unrealised gains. As UK rhetoric increasingly focused on taxing wealth rather than income, many believed the UK would follow.
It did not.
The November 2025 Budget introduced no exit tax whatsoever:
No deemed disposal tax on assets when leaving
No wealth departure levy
No exit-based capital gains crystallisation
For UK Exit Tax Wealth Planning, this is profoundly important. It preserves mobility for:
British expatriates already resident overseas
Entrepreneurs planning business exits
Family offices running globally diversified structures
International investors assessing UK exposure
Simply put, emigration itself does not trigger a tax charge.
But — and this is critical — no exit tax does not mean no continuing UK tax exposure. The UK still operates several powerful rules that follow individuals after departure.
Temporary Non-Residence: The Hidden Exit Trap Still in Force
Even without an exit tax, the UK’s temporary non-residence rules remain fully operational. If an individual leaves the UK and returns within five complete tax years, certain capital gains realised during the overseas period can still be taxed on return.
This applies to:
Sale of shares
Business exits
Property disposals
Carried interest
Private equity and venture distributions
For expats and entrepreneurs, this makes exit timing absolutely critical. A poorly timed return can re-activate UK capital gains tax exposure even after years abroad. Any credible UK Exit Tax Wealth Planning strategy must therefore integrate long-term residence modelling with exit execution.
The Real Structural Shift: Residence Has Replaced Domicile
While the absence of an exit tax was welcome, the deeper structural change affecting expatriates lies elsewhere.
The traditional UK non-dom regime has now been abolished. Domicile is no longer the dominant factor. Instead, the UK has moved decisively toward a residence-based wealth taxation framework.
This means:
Long-term UK residence now triggers inheritance tax exposure
Offshore trusts lose automatic protection
Non-dom status no longer shields foreign wealth indefinitely
This is a fundamental philosophical shift. It aligns the UK far more closely with continental European wealth taxation models — even without introducing a formal wealth tax.
For international investors, this is arguably more important than any hypothetical exit tax.
If you’re unsure how a residence-based tax framework may affect your long-term plans or offshore structures, now is the time to seek clarity. Speak with the specialist team at Global Investments to understand your position and plan your next steps with confidence.
Trusts and Offshore Structures: Protection Is No Longer Passive
One of the most significant outcomes of the Budget concerns offshore and excluded-property trusts.
Under the old regime, many non-doms structured foreign wealth into excluded-property trusts that remained permanently outside the UK inheritance tax net. That position no longer holds for long-term UK residents.
Once an individual becomes classed as a long-term UK resident:
Their offshore trusts can enter the relevant property regime
Trusts now face 10-yearly inheritance tax charges
Exit charges apply on capital distributions
A limited £5 million cap on periodic charges was introduced for certain legacy trusts, but this only assists very large pre-2024 structures. It does not reinstate the old level of protection.
For most internationally mobile families, this means:
Trusts must now be actively managed
Residence history determines long-term tax exposure
“Set and forget” offshore planning is over
This is now one of the single largest risks in UK international wealth structuring.
Inheritance Tax: A Quiet but Relentless Expansion
Another major outcome of the 2025 Budget lies in what was not changed. The inheritance tax nil-rate band remains frozen at £325,000, and the residence nil-rate band also remains capped. As asset values rise, this quietly drags more families into inheritance tax every year.
For expatriates, this creates a dangerous illusion: Many believe that simply living abroad removes UK inheritance tax exposure. That is often not true.
UK inheritance tax still applies to:
UK property
UK business interests
UK-domiciled assets
Trust structures linked to long-term residence
Combined with the abolition of the old non-dom rules, UK inheritance tax exposure is now broader, deeper, and harder to avoid than in any decade prior.
Why the Absence of an Exit Tax Still Matters Enormously
It cannot be overstated how significant it is that the UK avoided introducing an exit tax.
If an exit tax had been imposed:
Entrepreneurs would face immediate CGT on unrealised gains
Private business exits would become uneconomic
Long-term capital planning would be severely restricted
Severe capital flight would likely occur
By avoiding it, the UK has preserved:
International labour mobility
Entrepreneurial liquidity
Cross-border family restructuring
Global investor confidence
From a macroeconomic view, this maintains the UK’s competitiveness. From a UK Exit Tax Wealth Planning perspective, it preserves flexibility — but only for those who plan correctly.
Residency Risk Now Matters More Than Ever
The new regime effectively creates a new priority for international families: Managing UK residency is now the central wealth-planning risk variable.
It is no longer enough to be “non-dom”. Instead, individuals must now model:
How many years they reside in the UK
When long-term residence triggers occur
How trusts will be taxed after that point
How re-entry to the UK affects historic gains
This represents a seismic shift in international planning strategy.
What This Means for Expats, Non-Doms and International Investors
Taken together, the 2025 Budget signals that the UK is evolving into:
A residence-based wealth taxation system
A jurisdiction with expanding inheritance tax reach
A country that taxes structure complexity rather than simplicity
For expats and global investors, this creates a new reality:
Offshore trusts face future IHT exposure
UK property retains permanent IHT risk
UK residency years now drive wealth taxation
Exit remains tax-efficient — but only if planned correctly
The UK remains investable — but not tax-passive
Strategic Actions High-Net-Worth Families Should Consider Now
In this new environment, effective UK Exit Tax Wealth Planning is no longer theoretical — it’s operational.
Key strategic reviews now include:
Full residence history modelling: Determining when UK long-term residence thresholds are met.
Trust exposure analysis: Reviewing whether trusts will enter the relevant property regime.
UK property IHT optimisation: Modelling long-term inheritance tax impact on UK real estate.
Exit sequencing planning: Ensuring capital exits do not fall inside temporary non-residence traps.
Jurisdictional diversification: Reducing reliance on any single tax authority.
Multi-generational structuring: Planning not just for current owners, but for heirs under future UK rules.
Final Thoughts: No Exit Tax — But No Easy Ride Either
The November 2025 UK Budget delivered one of the clearest messages yet to globally mobile wealth:
There is no exit tax — but remaining connected to the UK financially has never been more complex or expensive.
From a UK Exit Tax Wealth Planning standpoint, this creates a dual strategy:
Leaving the UK remains tax-efficient if planned correctly
Staying long-term creates increasing inheritance and trust exposure
The era of passive non-dom protection is over. The era of active international structuring, residency modelling, and long-term succession planning has firmly begun.
For expatriates, non-doms and international investors, the question is no longer: “Will the UK introduce an exit tax?”
It is now: “How exposed is my global wealth to the UK’s expanding residence-based tax net?”
If that question feels close to home, now is the time for clarity.
