Experts for Expats receives enquiries from people living all over the world who remain connected to the UK through citizenship, property, family, work or financial ties and are trying to understand one thing:
“What is my UK tax position now that I live internationally?”
Some people contact us before leaving the UK, wanting to understand how their move could affect their tax position. Others have already relocated abroad and are trying to establish whether they are still considered UK tax resident. Many divide their lives between multiple countries and are uncertain where they are actually resident for tax purposes.
A large number of enquiries received by Experts for Expats come from people who:
- Still complete UK self-assessment tax returns while living overseas
- Receive unexpected HMRC correspondence through Nudge Letters
- Are unsure whether they should continue filing UK tax returns
- Misunderstand schemes such as the Non-Resident Landlord Scheme
- Incorrectly assume that moving abroad automatically removes all UK tax obligations
What quickly becomes clear is that the technical residency question is rarely the real concern.
Usually, people are trying to understand the practical financial consequences of living internationally, including:
- Whether HMRC can still tax them
- Whether they could accidentally remain UK tax resident
- Whether they might face double taxation
- Whether they can continue using UK investments efficiently
- How UK property, pensions or overseas income may be affected
The difficulty is that UK tax residency rules are rarely straightforward once someone’s life begins spanning multiple countries. Owning UK property, returning regularly to visit family, working remotely from Britain or maintaining overseas business interests can all affect residency status in ways many people do not expect.
Ultimately, UK tax residence status is determined using the Statutory Residence Test. However, understanding how the rules apply in real life is often far more complicated than many internationally mobile people initially assume.
This article has been written to identify and respond to some of the most common UK tax residency questions British expats ask through Experts for Expats.

This article is intended as a general guide only and should not be considered tax advice. UK tax residency rules are highly fact specific and international tax matters can become complex very quickly. Always seek independent professional advice before making financial or tax decisions relating to residency status, overseas income or relocation planning.
Am I still considered a UK tax resident if I move abroad but keep ties to the UK?
This is probably the single most common residency concern we see.
Many British expats assume that once they leave the UK, they automatically become non-resident for tax purposes. In reality, HMRC looks at a much wider picture using various ties through the Statutory Residence Test.
The enquiries we receive often involve situations such as:
- Keeping a UK home
- Having a spouse or children remain in Britain
- Travelling back frequently for work
- Spending part of the year in the UK
- Running a UK business while living overseas
- Commuting between countries
In many cases, people are surprised to discover that UK residency status is not simply about where they “live”.
The UK’s Statutory Residence Test looks at:
- How many days are spent in the UK
- Accommodation availability
- Work patterns
- Family connections
- Previous UK residency history
- Other connecting factors known as “ties”
Someone can genuinely feel they have emigrated while still remaining UK tax resident under HMRC rules.
This is particularly common among British expats living in places such as Dubai, Switzerland or Portugal while continuing to maintain strong UK connections.
How do I avoid being taxed twice when moving between the UK and another country?
Another major concern is double taxation.
Many enquiries received by Experts for Expats involve people who suddenly discover that two countries may both believe they have taxing rights over the same income.
This often happens when:
- Moving country during a tax year
- Working remotely across borders
- Receiving pensions from one country while living in another
- Owning overseas rental property
- Becoming resident elsewhere while retaining UK income
People are often surprised to discover that tax residency and tax liability are not always the same thing. Even if someone becomes non-resident in the UK, certain UK-source income may still remain taxable in Britain.
At the same time, their country of residence may also expect worldwide income reporting.
This is where double taxation agreements become extremely important.
Many people first contact Experts for Expats after trying to interpret a tax treaty themselves and realising the situation is more complicated than expected.
The challenge is that treaties do not always eliminate tax completely. In many situations they simply determine:
- Which country gets primary taxing rights
- Where credits can be claimed
- How residency conflicts are resolved
The practical application can become highly technical once pensions, investments, capital gains or business income are involved.
When do I officially become non-resident for UK tax purposes?
This question appears constantly in relocation planning enquiries.
Many British expats want to know:
- Whether they become non-resident immediately after leaving
- Whether they need to complete a full tax year abroad
- How split year treatment works
- How many days they can return to the UK
- Whether working visits create problems
The timing of departure can significantly affect tax exposure.
For example, someone leaving halfway through the tax year may qualify for split year treatment, which can separate UK and overseas periods for tax purposes. However, eligibility depends on meeting very specific conditions.
People are often surprised by how easy it can be to accidentally retain UK residency status after moving abroad.
Many enquiries received through Experts for Expats involve people who have already moved abroad but only later realise they may not have actually broken UK tax residency correctly.
Can I have residency in two countries at the same time?
Yes and this causes enormous confusion.
Dual residency situations appear regularly in enquiries we receive from people all around the world where there’s an assumption there must be one simple answer to residency status. In reality, different countries can apply entirely different residency tests.
This can lead to situations where:
- The UK considers someone resident
- Another country also considers them resident
- Both countries expect tax reporting
This is where treaty “tie breaker” provisions become important.
However, many people underestimate how complicated dual residency can become once family location, permanent home availability, centre of vital interests, business activity and long-term intentions all begin to interact.
The issue becomes even more significant when wealth, investments and succession planning are involved.
In many cases, the real concern behind the enquiry is not residency itself but uncertainty around:
- Capital gains tax
- Inheritance tax exposure
- Reporting obligations
- Overseas investment structures
- Pension withdrawals
Why am I still paying UK tax if I’m non-resident?
This is another extremely common misunderstanding.
Many British expats believe becoming non-resident means they no longer deal with HMRC at all.
In reality, UK-source income can still remain taxable in Britain even after someone leaves the country.
Common examples include:
- UK rental property income
- Capital gains relating to selling a UK property
- Employment linked to UK duties
- Certain pension income
- UK business income
This often creates confusion because people separate “residency” from “tax” but the reality is that residency status affects how the UK taxes worldwide income, but it does not necessarily remove UK taxation on income arising within the UK itself.
Why residency questions often become bigger financial planning questions
One of the most interesting patterns in the enquiries received by Experts for Expats is that residency questions rarely stay isolated for long.
Very quickly, they begin connecting into wider issues such as:
- pension transfers
- overseas investments
- property ownership
- inheritance planning
- business structures
- currency movement
- future relocation plans
This is why many people initially searching for a simple “Am I resident?” answer eventually realise they need coordinated tax, financial and legal guidance across multiple countries.
The technical rules matter, but so does understanding how they apply to real life.
I’m the owner or director of a company in Dubai or another low-tax country. What happens if I temporarily move back to the UK?
This is a type of enquiry that Experts for Expats is receiving more frequently, particularly since remote working became more common and especially since the conflict in the Middle East.
Many people establish companies in jurisdictions such as Dubai’s free zones, Cyprus, Malta and other lower-tax jurisdictions while the individual was living overseas and operating internationally.
The problem arises when the business owner returns to the UK either temporarily or permanently and assume that, because the company itself is overseas, the UK cannot become involved from a tax perspective.
But that isn’t always the case and the relocation can change the tax liability for the company as well as the individual. Questions that business owners should be asking when relocating back to the UK, but often do not include:
- Could the individual accidentally become UK tax resident again?
- Could the company itself become UK tax resident?
- Where is “central management and control” taking place?
- Does running the business from the UK create UK corporation tax exposure?
- Could HMRC argue that income should be taxed personally in the UK?
- How many days can someone safely spend back in Britain?
For owner-managed businesses, the distinction between the individual and the company often becomes extremely important.
If strategic decision making and management activity begin taking place from the UK, HMRC may potentially argue that the company itself has UK tax exposure, even if incorporated elsewhere.
This becomes particularly relevant for overseas business owners in the following common industries:
- Consultants
- Online business owners
- Investment businesses
- Crypto-related businesses
- Service companies
- Digital nomads
The enquiries we receive where these situations potentially become real are not always connected to the original reason someone contacts Experts for Expats. Instead, the issue often reveals itself later through ordinary life events and practical realities rather than deliberate tax planning.
Someone may originally be asking about visas, property, schooling or pensions before gradually realising that returning to the UK, even temporarily, could create entirely separate residency and business tax implications.
A family illness may require someone to spend extended periods back in Britain. Others return temporarily because of children’s education, relationship changes, instability overseas or visa complications affecting their ability to remain abroad.
More recently, Experts for Expats has also seen enquiries linked to the conflict involving Iran and wider Middle East instability, where people based in the Gulf have faced sudden travel disruption, airspace closures, business uncertainty and concerns about whether they may need to return to the UK unexpectedly or for longer than originally planned.
What initially feels like a short-term or informal move can gradually create far wider UK tax and residency implications than expected.
How Experts for Expats can help
UK tax residency questions are rarely straightforward once multiple countries, income sources and financial arrangements become involved.
Increasingly, many people already have a better understanding of the terminology because they have researched their situation using AI tools and prompts before contacting Experts for Expats. However, while AI can help identify possible issues, applying residency rules to real-life international situations often requires specialist review.
Experts for Expats acts as an introduction and coordination service for people living internationally. Enquiries are reviewed before introducing individuals to independent specialists who can help:
- Assess likely UK residency status and review double taxation exposure
- Bring UK tax affairs up to date
- Understand international reporting obligations
- Coordinate advice across multiple countries
- Explore unforeseen issues and help resolve them through meticulous tax planning
In many cases, the objective is not simply answering one residency question, but helping people better understand the wider financial and tax implications of living internationally.
