UK Non-Dom Laws Have Changed In 2025, But How Much?

The UK has been home to one of the oldest and most well-known non-dom regimes (preceding the 20th century even), but after a great deal of controversy and back and forth among politicians and political parties over the last year or so, it was finally officially ended as of the 6th of April 2025.

However, as dramatic as that sounds, the official end of the UK’s non-dom regime doesn’t necessarily mean that everything has changed overnight. The reality is quite different, and as is the nature of everything even remotely bureaucratic, the practical implementation of these laws isn’t something that’ll happen overnight or, potentially, even within this government’s term.

 

What Is a Non-Dome Regime?

 

By definition, a classic non-domicile regime allows individuals who live in a country but are legally domiciled elsewhere to benefit from preferential tax treatment.

Under this system, residents are typically taxed only on income and gains earned within the country, while foreign income may remain untaxed unless it’s brought into the country.

The main appeal in this option lies in flexibility and potential tax savings for those with international finances, investments or business interests – naturally, it’s wealthy people earning big money overseas who really stand to benefit.

Non-dom status distinguishes residency from domicile, meaning someone can live in a country long-term without being considered a permanent resident for tax purposes, creating a legal pathway to reduce domestic tax liabilities.

 

What Were the UK’s Non-Dom Regulations Pre-2025?

 

So, in line with the above definition of a non-dom country, before April 2025, individuals residing in the UK but claiming a permanent home (that is, a domicile) abroad could choose for the remittance basis of taxation. Essentially, this meant that they would pay UK tax as normal on all income and gains earned and brought into the country, but they wouldn’t need to pay tax on worldwide earnings.

According to previous UK law, after seven years of UK residency, non-doms were then required to pay an annual fee for this privilege – £30,000 at first, increasing to £60,000 after twelve years.

Understandably, this regulation was particularly advantageous for very wealthy people who were earning a decent amount of money overseas.

 

 

Why Was the UK’s Non-Dom Status Controversial?

 

Nobody will argue that the UK’s non-dom status has long been a point of contention and, unsurprisingly, a topic of debate among opposing politicians, especially in recent years.

On one side, supporters argue that the law encourages wealthy people – entrepreneurs and investors alike – to use the UK as a base, which, in turn, boosts the economy by means of property purchases, business investments and spending. They may not be directly paying tax on those earnings accrued abroad, but they were still going to inject a lot of money back into the UK’s economy by other means. Indeed, this regime offered such individuals flexibility and fairness, allowing them to avoid double taxation while still contributing to the local economy. In this sense, it was seen as kind of a win-win.

Critics, however, saw the system as inherently unfair. They argued that it gave the wealthy a legal loophole to avoid paying taxes that ordinary residents must, undermining the fairness of the tax system. The perception of inequality grew as high-profile individuals and families benefitted from the scheme while others shouldered the full tax burden. Thus, they argued that the country’s non-dom status should be revoked, forcing these people to pay tax on income brought into the UK.

But, for obvious reasons, it’s not as simple as this. The immediate repercussion of this would be that wealthy people would simply choose not to reside in the UK – why would they want to be taxed twice? Plenty of other countries offer non-dom laws so it would be easy as pie for them to relocate, meaning that their money and investment would stop being injected into the UK’s economy and go elsewhere – a big loss for the UK.

Many believe that ending the UK’s non-dom status – or promising to do so, at least – was no more than a campaign promise by the Labour Party, a supposed commitment to making the country’s tax system “fair” and to stop helping the rich become richer. But, on the other hand, opposition disagree – they’ve implemented this change, haven’t they? As of the 6th of April 2025, the UK is no longer a non-dom regime.

Well, it’s a lot more complicated than that, and as much as nobody wants to hear it, this discussion is far from over.

 

How Have the UK’s Non-Dom Regulations Changed?

 

When it comes to technicalities, the UK’s non-dom regulations certainly have changed, but the practical and immediate changes are actually not nearly as drastic as the government has made them sound. By announcing that the UK is officially no longer a non-dom regime and “everyone will now be taxed fairly”, there’s a direct implication that suddenly, the wealthy who previously benefited from these laws will now be paying oodles more in taxes.

But, that’s not the case, and there are many reasons for this – first, practically speaking, it’s just not possible to make that kind of change so immediately; second, many argue that it’s not actually beneficial for the UK economically. Thus, critics of the Labour Party assert that the government may have made this change to make voters happy, but they# way in which they’ve implemented it means that there aren’t actually any real changes that’ll be seen for a minimum of three years – thus, no real changes means no downsides and no negative fallback on them. Basically, the argument here is that the government has been able to curry favour by being loud about eliminating the UK’s non-dom status without having to be responsible for the implications it’ll actually have on the economy when it’s implemented- after all, who knows who will win the next election!

So, with both arguments in mind, how have the UK’s non-dom regulations actually changed since April 2025?

Officially speak, the UK completely abolished the regime and replaced it with a “residence-based taxation system”. This means that all UK residents are now taxed on all income and gains, both domestic and worldwide, regardless of their domicile status. Ultimately, domicile status is now pretty much irrelevant in the tax system (well, in theory).

Now, here’s where we shift from what seemed like a black and white to a whole lot of grey. The government announced that in order to ease this transition, they would introduce a four-year Foreign Income and Gains (FIG) regime. FIG offers 100% relief on foreign income and gains for new arrivals to the UK for their first four years of tax residence (as long as they haven’t already been a UK tax resident in any of the 10 years prior to their arrival).

For those who were already operating as non-doms between 2017/18 and 2024/25 may qualify for asset rebasing to 5 April 2017 values – this means that they’ll be paying significantly reduced taxable capital gains.

Also, there is a Temporary Repatriation Facility (TRF) that has been introduced to try and encourage people to bring in as much money from abroad as possible in the next few years – essentially, they’ll be able to remit foreign income and gains that were accrued prior to April 2025 at a reduced tax rate of 12% for the first two years and 15% for the third year.

So, undoubtedly, these are some big changes. But, while they were clearly already hesitant to introduce this in the first place (which is clear by the introduction of the TRF and FIG regulations), there’s been a lot of backlash. Not only backlash, but a report published by New World Health in conjunction with Henley & Partners asserted that more than 10,000 millionaires left the UK in 2024 – that’s a 157% increase from 2023. While we can’t absolutely say that that’s all definitely due to the non-dom change (because sure, there may be a few another small variables), there’s absolutely no denying that it’s a huge contributing factor, and it’s something they can’t afford to ignore. Indeed, often, the expectation of a law change will have the same effect as its actual implementation, and it can be just as – if not more – damaging.

What’s the UK’s Future As a No Longer Non-Dom Regime?

 

It’s tough to say, but it certainly seems like there’s been a lot more immediate backlash than anybody expected, even those who were vehemently against the change.

But it’s also really worth noting the caveats that were added to the abolition of the non-dom regime – that is, FIG, TRF and the Capital Gains Tax (CGT) rebasing. While they’ve been floated as transitional regulations, there’s also no way around the fact that they’re also kind of pausing the actual implementation of the change for most people it would affect.

That is, new residents still don’t need to pay tax for income and gains earned outside the UK unless they bring it back – just like under the non-dom regime. Those who were already operating as non-doms still have a massive incentive to remain in the UK because they’re paying significantly reduced rates for years to come (slightly more than before, but not much) and the TRF also means a massively reduced tax rate for the next three years for most other people too.

So, while these three regulations  -FIG, CGT rebasing and TRF – have been floated as mere caveats to the new laws and the supposed abolition of the UK’s non-dom regime, what they actually do, in reality, is negate the abolition (in most cases) for at least the next three years.

Sure, there are some changes and many people who will be paying slightly higher taxes, but it’s definitely not a switch from non-dom to a complete abolition of the non-dom regime. For all intents and purposes, it’s a label change with a whole lot of footnotes.
