Relocating internationally is exciting — but it’s one of the easiest times to make expensive, lasting tax mistakes. Small decisions made at the wrong time can cost you thousands.
UK tax is fundamentally driven by residence, determined under the Statutory Residence Test (SRT). Before thinking about tax rates, allowances, or planning, you need to know:
That’s where we can help you by identifying your SRT date and if split year treatment (SYT) applies
Yes, you can be taxed in two countries at once, but you are not usually taxed twice on the same income.
This can happen because:
For example, the UK may tax you on income earned within its borders, while another country taxes you as a resident
However, double taxation treaties (DTT) and domestic rules are designed to prevent you paying tax twice on the same income. Typically, one country has the primary right to tax, and the other gives relief (usually a tax credit) for tax already paid.
We can help you determine where you will pay taxes under the DTT
Yes, possibly. Leaving the UK does not automatically end your UK tax obligations.
You may still pay UK tax if you have:
If you become non-resident, the UK generally only taxes your UK income and gains, and if you achieve split year treatment (SYT), will not tax your worldwide income even in the tax year of departure
We can work through all your income positions, the SRT and SYT applicable to you, and give you certainty on your taxes
You need to tell HMRC as soon as your circumstances change—and report it formally after the tax year.
You should tell HMRC about:

Conversation
is often all it takes to protect thousands in tax
Your residency status, the exact date you leave or arrive, what income you hold and where — these all interact in ways that aren’t obvious. And by the time most people realise there was a decision to make, they’ve already made it.
HMRC can investigate and assess tax going back years. A residency miscalculation at the point of departure can resurface long after you’ve settled in.
Without correct planning, two countries can simultaneously and legitimately claim tax on the same earnings.
You must notify HMRC of residency changes even when no tax is due. Missing this triggers automatic penalties that compound over time.
The timing of asset disposals relative to your departure date can make an enormous difference. Once you’ve moved, that window closes permanently.
The exact date you leave or arrive in the UK can determine your tax residency status under the Statutory Residence Test. This is where most people go wrong: they wait until after the move. By then, options are limited, and decisions are locked in.
Determines whether you’re a UK resident for tax in a given year based on precise day counts, ties, and working patterns.
Can halve your UK tax liability in the year you move, but qualifying depends on the specific facts of your departure or arrival date.
Disposing of assets before or after establishing non-residence leads to very different CGT outcomes. The window to plan around this closes when you leave.
Late notifications carry automatic penalties even when no tax is due. The obligation arises at specific points in the process, not just at tax return time.
This is not generic accountancy. We work exclusively with individuals and families in international transitions, people whose tax situation has become complex and who need answers they can act on.
01 — RESIDENCY
We establish your precise UK tax residency status before you commit to a move date, counting your days, assessing your ties, and applying the SRT correctly.
02 — YEAR OF MOVE
We assess all eight HMRC cases to determine if SYT applies to you, then apply it correctly so you’re not over-taxed in the year you move.
03 — ASSETS
Strategic advice on UK and overseas asset disposals, when to sell, how to structure ownership, and how to avoid avoidable CGT charges before and after your move.
04 — PROTECTION
We navigate the UK’s 130+ country treaty network to ensure you are never paying tax twice on the same income, wherever in the world your life spans.
05 — COMPLIANCE
Every return filed, every notification made, every deadline met on time and correctly. Penalties are never a concern when everything is handled properly from the start.
06 — INCOME
Rental income, dividends, business interests across borders, we clarify what stays in the UK tax system and how to structure everything most efficiently.
Happy Clients
“Thanks Mark for yet another clear explanation of an area with many complexities in a language us normal folks can understand!”
“Great level of knowledge and expertise. Opened the lid on a tax issue that we thought was covered off and gave great advice that helped take things forward.”
“Professional and resourceful! We’ve received value-added, tailored financial advice to solve our immediate needs.”
You’re leaving for work, lifestyle, retirement, or family. Before you go, we establish your residency position, plan the timing, and ensure you’re not carrying unnecessary UK obligations into your new life.
Coming back after time overseas means re-entering the UK tax system, often with overseas income, investments, and property in the mix. We ensure you arrive with clarity, not complications.
Your life doesn’t fit neatly into one country’s tax framework, and most advisers aren’t equipped to handle it. We specialise in multi-jurisdiction situations that others shy away from.
Non-resident property owners, overseas investors in UK assets, your UK tax exposure doesn’t disappear because you live abroad. We ensure your investments are structured and compliant.
If you’re asking any of these, you’re in exactly the right place — and the right time to get answers is now, before the move.
Have a question that isn’t here? We’re happy to answer it — no obligation, no pressure.
The SRT applies a structured series of tests. First, automatic overseas tests that can confirm you as non-UK resident. Second, automatic UK tests that confirm you as resident. If neither applies clearly, “sufficient ties” tests assess your family, accommodation, work, and time in the UK. The interaction is often counterintuitive — a single extra day or one additional tie can shift your entire residency position for the year.
Potentially yes — and significantly. SYT divides your tax year at the point of departure or arrival, so you’re only taxed as UK resident for the portion you were actually here. Qualification isn’t automatic: HMRC defines eight specific cases and you must satisfy at least one. We assess all of them and apply the most beneficial correctly in your return.
Leaving removes you from most CGT — but not all. UK residential property always remains within UK CGT regardless of your residency. And if you return within five years, gains made overseas on certain assets can be brought back into UK charge under the “temporary non-residence” rules. Pre-departure disposal planning is therefore critical for anyone with significant assets.
The UK has double tax treaties with over 130 countries. These allocate taxing rights and can provide relief — but claiming it isn’t automatic. It typically requires applying for treaty protection, understanding which articles apply to your income types, and sometimes making specific elections. We navigate this for you, working with the specific treaty in play for your countries of residence.
Your obligations depend on your circumstances but commonly include: completing a Self Assessment return for the year of departure or arrival (even with no UK tax due), notifying HMRC of residency changes, reporting UK-source income while non-resident, and potentially filing under the Non-Resident Landlord scheme for UK property. Missing any of these triggers automatic penalties that grow over time.
The right conversation — before your move — costs far less than the wrong outcome after it. We offer a straightforward initial consultation to understand your situation and give you the clarity you need to move forward confidently.

The nomad’s position depends on the Statutory Residence Test (SRT):
If you remain UK resident, the UK taxes your worldwide income. If you become non-resident, the UK generally taxes only your UK-source income.
Whereas a seafarer may live in the UK, they will have achieved the standard required for Seafarers’ Earnings Deduction (SED), and they have the HS205 record of their days afloat
Lifestyle labels like “nomad” or “seafarer” don’t determine your tax, the facts do, and we will guide you through the process to achieve this status
Non-residents still pay UK tax on UK property income and gains.
Rental income: taxed in the UK on net profits (after allowable expenses)
Capital gains: UK tax applies when you sell UK property, even if you’re non-resident
You will need to file a UK Self-Assessment tax return
The Non-Resident Landlord Scheme will apply to rental income
Being non-resident does not remove UK tax on UK property; the UK always taxes UK land and property and our specialist team will be able to assist you with all your compliance requirements
