Is a UK Exit Tax on the Horizon in 2025?
What It Could Mean for Individuals and Business Owners
There’s been increasing talk in recent months around the potential introduction of a UK exit tax—a charge applied to individuals who leave the UK and become non-resident for tax purposes. While no formal legislation has been proposed, the topic has surfaced in fiscal policy discussions and the financial press, driven largely by government concerns over high-net-worth individuals moving wealth offshore.
The backdrop? A rise in wealthy individuals and entrepreneurs relocating to low- or no-tax jurisdictions such as the United Arab Emirates and the Isle of Man—particularly following last year’s tax changes. An exit tax could be one way the government looks to retain revenue by capturing unrealised gains when individuals leave the UK tax system.
Why Now?
What may surprise some is that, unlike many other countries, the UK currently does not impose an exit tax on individuals. In contrast, jurisdictions like Australia, Canada, and the US have had such measures in place for some time. These rules are designed to stop taxpayers from avoiding future capital gains tax simply by moving abroad.
The idea is to ensure that any value created while a person is UK-resident is taxed before they leave—even if the underlying assets are only sold after they’ve gone.
In today’s globally mobile world, and with mounting pressure to protect the UK tax base, it’s understandable why an exit tax is being discussed, even if only speculatively at this stage.
How Exit Taxes Work Elsewhere
Although the specifics vary by country, most exit tax regimes work on similar principles. Here’s a snapshot of how they tend to function:
-
Deemed Disposal of Worldwide Assets
When someone leaves a country, tax authorities may treat them as if they have disposed of all their global assets—on paper, at least—at current market value. This ‘deemed disposal’ triggers a capital gains tax charge, even though nothing has actually been sold.
Assets commonly included in this calculation might be:
- Overseas property
- Shares and securities
- Investment portfolios
- Other non-UK assets
UK land and property are already subject to UK tax regardless of residency status, so if an exit tax is introduced this type of asset would be expected to be excluded.
-
Company Residency Changes
Although less common, companies can also migrate out of the UK. In such cases, current UK tax legislation already treats the company as having sold its chargeable assets at market value immediately before leaving—taxing any resulting gains. This mechanism exists to prevent businesses from avoiding tax by moving operations or ownership structures offshore. Again any assets which remain in the UK tax net after company has migrated would not be subject to an exit charge.
What Could a UK Exit Tax Mean for Those Planning a Move?
Should a UK Exit Tax be introduced, the implications for those with significant overseas holdings could be considerable.
Individuals who’ve held international assets for many years—such as business interests, investments, or property—could find themselves facing a sizeable tax bill upon departure, even if they’ve made no actual sales. This could significantly alter the financial and tax planning landscape for entrepreneurs, investors, and globally mobile families alike.
What About Those Moving To the UK?
In countries that operate exit tax regimes, there are often corresponding rules for new arrivals.
Australia, for example, deems individuals to have acquired their assets at market value when they become tax-resident—ensuring that only future gains (while resident) are taxed locally. If a UK Exit Tax were to mirror this model, we might see a similar ‘step-up’ in asset values for those becoming UK tax residents.
This would help avoid double taxation and bring clarity for inbound individuals planning to make the UK their home.
So, is a UK Exit Tax likely to be introduced?
At the time of writing, nothing has been confirmed. No draft legislation has been published, and we remain in the realm of speculation.
That said, the broader political and fiscal climate—particularly concerns about a “flight of wealth”—means this is an area to watch. As part of wider discussions about how the UK remains competitive, encourages investment, and retains its tax base, a UK exit tax could be one of several measures considered in the future.
