POPPING THE BALLOON: WHY LEAVING THE UK MIGHT NOT QUITE BE THE ‘CLEAN BREAK’ FROM UK TAX

So you’ve left the UK for pastures new. The sun is shining. You're making more money. You’re enjoying a great quality of life in a new country. In fact, you’re totally de-mob happy. 

Even better, as a non-UK resident, UK taxes are a dim and distant unpleasant memory, right. Right?
Wrong. 

I don’t necessarily see my role in life as chief balloon popper. However, there are some Uk tax things you should bear in mind before declaring yourself a tax exile. 

Am I really non-UK Resident (“NR”)?

Up until 2013, the UK didn’t really have a statutory definition of residence for tax purposes. Yes, that’s as crazy as it sounds. Fortunately, the Statutory Residence Test (“SRT”) was introduced from 2013.

The idea is that it provides a degree of objectivity through a series of tests. Although a statutory test, other than in straightforward cases, it can still remain complex.

Generally speaking, one is either R or NR for the entire tax year (oddly, 6 April 20X4 to 5 April 20X5 in the UK).


However, one can qualify for split year treatment in certain scenarios meaning one can slice and dice the tax year into resident and non-resident periods.


A detailed consideration of the UK residence rules is beyond this article. But, certainly, as someone leaving the UK, I cannot stress how important it is to get advice in this area. It will be money well spent.


Scope of UK taxes for non-resident


So, where’s my balloon popping pin?


Let’s assume there’s no doubt that our client, Jimmy, is properly NR (he’s also UK domiciled for the short time remaining that this is relevant). Even HMRC agrees. He left the UK to move to the UAE with his family three years ago.


Jimmy, as they say, has his fingers in many financial pies. 


So, let’s look at his UK tax exposure.


Income

The basic principle is that UK residents pay UK income tax on worldwide income and NR’s pay UK income tax on UK source income. Obviously, our man Jimmy’s the latter.


But this is UK tax. So, there are exceptions. And exceptions to those exceptions!

Firstly, some UK income is specifically disregarded from UK tax in the hands of an NR. For example, dividends from UK companies is such income.


But not all dividends are the same. The dividends from Beaver Ltd, his private company, will be subject to an anti-avoidance rule. The rule is complex, and best explained by describing the mischief it targets.

Let us say Jimmy was reasonably smart. He realised that UK dividends paid whilst he was NR are outside of UK income tax as disregarded income. So, a few years before he left he simply allowed surplus profits to roll up in his company, knowing he could decant those funds tax-free whilst NR. Cunning, eh?


However, the anti-avoidance rule will say, that any of those rolled up profits that arose whilst he was UK resident are subject to a 5 year tail. If Jimmy takes them as a dividend then there is no immediate tax. But if his stay outside the UK is not more than 5 complete tax years then the dividend will become taxable on return. Note this does not apply to any profits of the Company that arose whilst Jimmy was non-UK resident.

This rule would not apply to the portfolio of listed shares.


Despite the role he has with Aardvark being with a UK company, being NR, with the duties being performed outside of the UK, this is not taxable in the UK and the employer should not operate PAYE.


The rental income from his UK properties will be taxable in the UK and he’ll be categorised as a Non-Resident Landlord. This imposes and obligation on a tenant or an agent to deduct and pay over to HMRC a withholding tax on rents received. The good news is one can apply for the NRL scheme, which allows one to receive rents gross. Assuming the individual has kept their nose clean with HMRC previously, then this is largely a formality.


However, the landlord still needs to pay tax through their self-assessment on the normal basis.

The rental income from Portugal will not be taxable in the UK.

The interest from the UK bank account will be taxable whereas the interest from the Jersey bank will not.

As a UAE tax resident, this income is outside the scope of UK corporate income tax (which counter-intuitively, can apply to natural persons) and there is no local personal tax.


Capital gains

UK CGT is a relatively simple tax. The general rule is that one pays UK CGT if UK resident. If not, then you don’t – even if assets are in the UK.

However, the jurisdictional scope has been extended to include UK real estate – regardless of whether residential / commercial or held directly / indirectly.


As such, if Jimmy sells any of his UK properties – regardless of whether he purchased them pre / post breaking his UK residence – then they are subject to UK CGT. He will need to report the disposals within 60 days – rather than simply waiting for the usual self-assessment deadline to come around.


If Jimmy sold his non-UK property then the position is a nuanced one. The basic rule is that this sale would be outside the scope of UK CGT. However, because he owned this property when he left the UK, there is a 5 year anti-avoidance tail. This means that if he sells the property there would be no immediate UK CGT. However, if he returns to the UK without being out of the UK in excess of 5 years, the gain crystallises on his return.

The same 5 year rule would apply to his holding in Beaver Limited.


As the UAE properties were acquired after he left the UK, there’s no UK CGT on a sale whilst NR.

Again, no local taxes would apply to these sales.


IHT

Under rules that will remain in place only until up to 5 April 2025, UK IHT was almost entirely based on a person’s domicile.


Broadly speaking, non-doms would only pay IHT on UK assets and not on their foreign ones unless they became deemed domiciled (usually after being resident in the UK for 15 years).


For UK domiciled individuals (regardless of residence status), and those who have become deemed domiciled, their worldwide assets are subject to UK IHT.


This was not good for expats as domicile is based not just on physical presence outside the UK but also on their intention to remain permanently or indefinitely in that same place. This meant that, as well as being uncertain, it was also precarious.


From 6 April 2025, there will also be a new residence-based system. Domicile is out. A person will be subject to UK IHT if they have been UK resident for 10 / 20 tax years. 


As such, long-term expats will have greater clarity by applying the 10 year test.

So, going back to Jimmy, at the moment, ignoring any reliefs that he might qualify for, he will still be subject to UK IHT on all of his assets as he has only been NR for three years.


However, fast forward a few years such that he has been NR for more than 10 tax years, he’ll only be subject to UK IHT on UK assets (the UK properties, the shares in Beaver Limited (subject to business property relief) and his UK bank account).


Conclusion

The above hopefully illustrates that one does not escape UK taxes simply because one has upped sticks, and unpacked one’s life overseas. The UK tax system has a long reach and never assume you’re ‘out of sight, and out of mind’ when it comes to HMRC.

Introduction More wealthy UK residents are exploring life overseas ahead of the 2026/27 tax year. Higher UK taxes, political uncertainty and a desire for a different way of living are all pushing people to look at alternatives. Four destinations stand out for high-net-worth UK individuals as at late 2025: 1. United Arab Emirates (Dubai) 2. Portugal 3. Switzerland 4. Malta Each offers a different blend of tax advantages, residency options and lifestyle. United Arab Emirates (Dubai) - Dubai is now the default choice for many UK entrepreneurs and professionals. Tax For individuals, there is currently no personal income tax on salaries, bonuses or most investment income, and no local capital gains or inheritance tax regime for individuals. There is VAT and a developing corporate tax regime, but personal tax remains far lighter than in the UK. The UK–UAE double tax treaty helps reduce the risk of the same income being taxed twice and needs to be considered alongside UK residence rules. Residency Common routes for UK nationals include: Employer- or company-sponsored residence visas Remote-worker visas for those employed or self-employed abroad Long-term “golden” style visas linked to investment, property or professional status Retirement options for over-55s. (All require private health insurance and periodic renewal.) Lifestyle Dubai offers a high standard of living, excellent connectivity and a large, well-established British community. Housing and schooling are expensive and the lifestyle can encourage overspending, but for many the tax position and opportunity outweigh the costs. Best for: Maximising net income and building or scaling a business in a dynamic, international city. Portugal - Portugal appeals to those who want EU residency, a milder climate and a slower pace of life. Tax The old NHR regime has closed to new applicants and been replaced by a newer incentive framework (often referred to as IFICI) aimed at certain professionals and activities. The UK–Portugal tax treaty reduces double taxation, and Portugal does not operate a classic wealth tax, though property-related charges can apply. (It's signed and ratified but not yet fully in force as of early 2026, which may slightly affect immediate tax planning). Residency Post-Brexit, common routes for UK nationals include: D7 visa – for those with sufficient passive income (pensions, investments, rentals). D8 / Digital Nomad visa – for remote workers with qualifying income from abroad. Work and other residence visas tied to employment or specific skills. These can lead to long-term residence and, ultimately, citizenship if physical presence and integration tests are met. Lifestyle Cost of living is generally below the UK (though higher in central Lisbon and the Algarve), English is widely spoken in cities, and the public and private healthcare systems are well regarded. There are large British and wider international communities. Best for: Those wanting EU residence, good quality of life and a balance of tax and lifestyle advantages. Switzerland - Switzerland attracts UK families who prioritise security, discretion and top-tier services. Tax Tax is set at federal, cantonal and communal level, so overall rates vary widely by canton. Well-chosen cantons can be very competitive for both individuals and companies. Private capital gains are not generally taxed, but there is an annual wealth tax on net assets, with rules depending on location. For suitable non-working individuals, some cantons still offer lump-sum (forfait) taxation, where tax is based on living costs rather than worldwide income, subject to minimum levels and conditions. Residency As non-EU nationals, UK citizens use: B permits – time-limited residence, often linked to work L permits – short-term residence for specific assignments C permits – longer-term settlement after sustained residence and integration Wealthy retirees and non-working individuals may be able to obtain residence based on financial self-sufficiency and, in some cantons, lump-sum taxation. Lifestyle High costs are offset by excellent infrastructure, schools and healthcare (with compulsory private health insurance). International communities are strong in Zurich, Geneva and other cities, though social life can feel more formal than Southern Europe. Best for: Those seeking stability, discretion and first-class public services and education, rather than the lowest day-to-day costs. Malta - Malta is a compact EU state with a very familiar feel for UK nationals: English is an official language and the legal and business environment is comfortable for British professionals. Tax Malta’s tax system and UK–Malta treaty can be particularly attractive where you hold significant foreign-source income. Under the Global Residence Programme, qualifying individuals can pay a favourable flat rate on foreign income remitted to Malta, while foreign capital gains kept offshore are generally not taxed in Malta. There is no separate wealth tax and no classic inheritance tax, though duties may apply to certain Maltese assets. The separate “golden passport” (citizenship by investment) route has been struck down by the EU’s top court, but residence programmes remain available. Residency Options for UK citizens include: Employer-sponsored Single Permits combining work and residence The Global Residence Programme for financially self-sufficient individuals meeting property and minimum tax thresholds Digital-nomad-style visas for remote workers Long-term residence after several years of compliant stay Lifestyle Costs (especially rent and property) are typically lower than in the UK outside the most fashionable areas. English is widely used in government and business, healthcare is solid, and London is only a short flight away. Best for: Those wanting an English-speaking EU base with favourable treatment of foreign-source income and a tight-knit expat community. How to decide & next steps - All four countries can work extremely well for UK high-net-worth individuals, but for different profiles: Choose Dubai if your priority is low personal tax on active income and you are comfortable with a high-energy city. Choose Portugal if EU residency, climate and lifestyle matter as much as tax. Choose Switzerland if stability, education and healthcare are at the top of your list. Choose Malta if you want an English-speaking EU base with flexible options for foreign income. The right answer depends on your overall wealth, income mix, family plans and how tied you remain to the UK.
