UK Non-Dom Tax Rules: The End is Nigh, But What Next?

UK Non-Dom Tax Rules: The End is Nigh, But What Next?

UK Non Dom Tax Rules
For over two centuries, the UK’s non-domiciled tax regime and its remittance basis has been a cornerstone of tax planning for wealthy expats and international families. 

It was introduced, along with income tax, by Willian Pitt the Younger at the very end of the 18th century. It was part of the fiscal firepower necessary to battle Napoleon Bonaparte. And, like income tax, it had pretty much been a constant feature of the UK’s system ever since.

But in March 2024, the then Chancellor, Jeremy Hunt, rang the death knell for the remittance basis, with Labour’s Rachel Reeves – who would succeed Hunt a few months later - declaring she would have abolished it anyway. 
The end is therefore very much nigh for the UK’s non-dom tax regime. More specifically, the end is 6 April 2025.

However, out with the old and in with the new’ goes the saying. As such, the ‘what comes next’ will reshape the tax landscape for non-doms, expats, and international investors with a UK footprint (or those considering creating one).  

What is Domicile (and Non-Domicile)?

Domicile is not a straightforward concept like tax residence. The latter is largely about physical presence (or otherwise) in a particular.

Instead, as well as physical presence, it also requires an understanding of your future intentions. Is a place somewhere that you intend to live permanently or indefinitely. 

There are two main types of domicile that I will discuss here:
• Domicile of origin: This is inherited at birth, usually from your father (if you think that is misogynistic then I don’t make the rules, OK?). You do not lose your domicile of origin. However, think of it as the foundations of a building. You can a domicile of choice on top it.
• Domicile of choice: You build a new domicile of choice by achieving two things. Firstly, by physically residing in place and, secondly, by forming the intention to stay in that same place permanently or indefinitely. Both must be present. 

As you can see, the domicile of origin is ready to rise back from the dead as soon as either ‘intention’ or physical presence changes.


On the other side of the coin, those with domiciles of origin outside the UK who have moved to UK have been able to reject a UK domicile of choice as long as they have not formed the intention to stay in the UK.

As I say, domicile of origin is a sticky thing. Difficult to shake and always ready to return.


The UK’s Non-Dom Rules (Before 6 April 2025)


“So what?” I hear you say.

Income tax & CGT

Well, under the current system, non-doms can elect to be taxed on something called the remittance basis for (broadly) up to 15 years of UK residence. This means: 

·      Foreign income and gains are only taxed if brought into the UK (remitted). 

·      A £30,000–£60,000 annual charge applies after 7 years of residence. 

·      After being resident for 15 /20 tax years, non-doms become deemed domiciled and their remittance basis rights are revoked. 


Inheritance Tax (IHT):

·      Broadly speaking, non-doms only pay IHT on UK assets. 

·      Foreign assets remain outside the scope unless they become deemed domiciled after 15 /20 tax years. 

·      For UK domiciled individuals, and those who have become deemed domiciled, then their worldwide assets are subject to UK IHT. Those non-doms approaching deemed domiciled could often use ‘excluded property trusts’ to park assets outside the scope of UK into the future.


These rules have been criticised for benefiting the ultra-rich. Regardless, they have also, undoubtedly, made the UK an attractive hub for international wealth, talent and investment. 


So, what do the changes look like from April?


The New Rules from 6 April 2025


Out with the old

As I’ve already alluded too, the remittance basis will be abolished and, more broadly, the link between domicile status and tax will be (almost) entirely removed.

There are some transitional rules for those former remittance basis users.


In with the new: Income Tax & CGT

From 6 April 2025, we will have a new and shiny regime called the Foreign Income and Gains (FIG) Exemption which includes: 

·      A 100% exemption for foreign income and gains for the first 4 years of UK residence for new arrivers in the UK (as long as have not been resident in the UK in any of the previous 10 years)

·      After 4 years, all worldwide income and gains will be fully taxable in the UK. 


In with the new: IHT: The End of the Domicile Link

There will also be a new residence-based system for IHT purposes: 

·      Non-doms will now become subject to UK IHT on their worldwide assets if they have been UK resident for 10 out of 20 years. 

·      This replaces the old 15-year deemed domicile rule with a 10-year exposure period, but crucially, non-doms leaving the UK will remain within the IHT net for up to 10 years after departure—making long-term estate planning far trickier. 


Once caught, IHT applies at 40% on worldwide assets. Controversially, this will include pre-existing offshore trusts and other structures (beyond the scope of this article but anyone effected should review as soon as possible). 


An Unexpected Fairytale for Expats?  


Long-Term Expats and IHT

For long-term expats, there new rules provide much more certainty around their IHT exposure. Previously, they would have had to be confident they were non-domiciled in order for their non-UK assets to escape the IHT net. Even then, any planning was dependent on not disturbing their domicile of choice – a precarious status (see the example of Barrie above).


However, someone who has not been resident in the UK for 10 out of the last 20 tax years will benefit from non-Uk assets in their death estate being outside the scope of IHT and will be able to make outright gifts of non-UK assets which are disregarded for UK IHT purposes.


It is worth noting that, unless some relief or exemption applies, then any person with UK assets will be in the scope of UK IHT. Even if they have never set foot there!


Returning Expats and the FIG Regime

The FIG regime also offers a clear plan window for returning long-term expats. If they have been non-UK resident for 10 years, the FIG regime will apply for the first 4 tax years.


Conclusion

The UK will shortly wave a tearful farewell to the remittance basis of taxation. Whether the new FIG regime will be attractive enough to tempt international mobile wealth remains to be seen.

However, as we have seen, the new rules do provide some un-expected benefits for long-term expats in the form of certainty when it comes to estate planning and an attractive benefit for those returning to the UK.

With that, I can hear the bell tolling.

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.
