For UK business owners who are seriously planning a UAE move — running a real business that will operate from the UAE, not just routing income through a UAE entity while continuing to live and work in the UK. This page sets out the UK Statutory Residence Test, the post-2025 non-dom regime, and the split-year rules, as of May 2026, and the friction points we see in practice.

The two halves of the question
Most UK business owners we speak to about a UAE move arrive with the same two questions, usually phrased less precisely than this. The first: when, exactly, does UK tax stop applying to me. The second: what does the UAE side actually look like once I am there. Until April 2025 these were difficult but well-trodden questions. The Statutory Residence Test had been in place since 2013, and the remittance basis gave non-domiciled UK residents a long-standing route to keep foreign income outside the UK net. From 6 April 2025, that option was removed.
Finance Act 2025 abolished the remittance basis and replaced it with a four-year Foreign Income and Gains regime aimed at people newly arriving in the UK. That is a different policy doing a different job. For someone leaving the UK for the UAE, the real point is that the comfortable middle ground — UK-resident but not paying UK tax on offshore income — has effectively closed. Residence itself now does most of the work. Where you are tax-resident in any given year, and how cleanly you exit when you leave, matter more than they used to (see how to leave the UK tax system properly for the operational checklist).
We advise on both sides of this question. The UAE side is our core work — 17 years on UAE structures since 2009, with IFZA Silicon Oasis our default free zone for UK business owners. For the UK side — SRT analysis, post-non-dom planning, exit timing, ongoing UK return obligations — we work alongside experienced UK qualified tax advisers who handle that work directly, so the UK side and the UAE side of the move run together, not across two firms that do not talk to each other. This page sets out, in plain English, what the UK rules say as of May 2026, where the friction points usually arise for business owners, and how we approach the engagement.
The Statutory Residence Test, in plain English
Whether you are UK tax-resident in a given tax year (6 April to 5 April) is decided by the Statutory Residence Test, set out in Schedule 45 to the Finance Act 2013 and explained in HMRC’s RDR3 guidance. The test runs in three layers, applied in order. You stop at the first layer that gives you a definite answer.
The three layers
First, the automatic overseas tests. If you meet any one of them, you are automatically non-resident for the year, and the rest of the test does not apply. The most relevant ones for a UK business owner leaving for the UAE are: fewer than 16 days in the UK in the year if you were UK-resident in any of the previous three tax years; fewer than 46 days if you were not; or full-time work overseas, broadly meaning an average of 35 hours a week of work outside the UK across the year, with fewer than 91 UK days and no more than 30 of those days being UK workdays.
Second, the automatic UK tests. If none of the overseas tests apply, you check these. You are automatically UK-resident if you spend 183 days or more in the UK in the tax year, if your only home in the year is in the UK (subject to specific conditions), or if you carry out full-time work in the UK across a 365-day period that overlaps the tax year. Most of the disputes we have seen turn on the “only home” test, where a UK property has been let out but kept available.
Third, the sufficient ties test. If neither set of automatic tests gives an answer, residence is determined by counting your UK days against your number of UK ties. This is where the real planning work happens for someone in the year of departure or the year after.
The four ties (or five, if you are a leaver)
There are five potential ties. Four apply to everyone; the fifth applies only to people who were UK-resident in any of the previous three tax years (HMRC calls these “leavers”).
- Family tie — your spouse, civil partner or minor child is UK-resident in the year.
- Accommodation tie — you have a place to live in the UK that is available to you for a continuous period of 91 days in the year, and you spend at least one night there (16 nights if it belongs to a close relative).
- Work tie — you do more than three hours of work in the UK on at least 40 days in the year.
- 90-day tie — you spent more than 90 days in the UK in either of the previous two tax years.
- Country tie (leavers only) — the UK is the country in which you spent the greatest number of midnights in the year.
The number of ties you can have before becoming UK-resident depends on how many days you spend in the UK and whether you are a leaver or an arriver. As a rough orientation for a leaver: four ties make you UK-resident at 16 days; three ties at 46; two ties at 91; one tie at 121; and at 183 days you are caught by the automatic test regardless. The exact thresholds are in the HMRC RDR3 tables, and they should be looked up rather than remembered.
Day-counting — less obvious than it sounds
A day generally counts as a UK day if you are present in the UK at midnight. Transit days are excluded if you arrive and leave the next day without doing substantive activity. The deeming rule — sometimes overlooked — can pull additional days into the count for leavers with three or more UK ties: where you are physically in the UK during the day but leave before midnight, and you have already had more than 30 such “qualifying” days, the rest in that year are treated as UK days. There are also exceptional-circumstances rules (capped at 60 days) for genuinely unforeseen events such as serious illness, but HMRC reads these narrowly.
Split-year treatment
For the deeper mechanics, see split-year treatment explained. By default, residence is an all-or-nothing matter for the tax year. Either you are UK-resident for the whole 6 April to 5 April period, or you are not. Split-year treatment is the statutory exception that allows the year to be divided into a UK part and an overseas part, so that foreign income and gains arising after departure are not pulled into the UK net for the whole year.
There are eight split-year cases in Schedule 45. For someone leaving the UK for the UAE, three are usually in play. Case 1 applies where you start full-time work overseas. Case 2 applies where you accompany a partner who is starting full-time work overseas. Case 3 applies where you cease to have a UK home. Each case has specific tests for the date the overseas part of the year is treated as starting, and each requires that you actually become non-resident for the following tax year — so split-year only crystallises in retrospect.
The practical point for business owners: split-year is helpful, but it is not automatic and it is not a get-out-of-jail card. Case 1 in particular requires a genuine pattern of full-time overseas work — not nominal employment with a UAE entity while continuing to run the UK business from your laptop. ICAEW Tax Faculty has flagged repeatedly, in its TAXguide series, that HMRC reviews of split-year claims focus on whether the working pattern after departure is consistent with the overseas-work requirement. Plan the move so that the facts genuinely fit, not just the form.
The end of the remittance basis and what replaced it
Until 5 April 2025, a UK-resident but non-UK-domiciled individual could elect for the remittance basis. Foreign income and gains were not taxed in the UK while they remained offshore; they were taxed only when remitted. The regime had been narrowed several times — most recently by the deemed-domicile rules from April 2017 — but it remained the central planning device for UK residents with income from abroad. From 6 April 2025, the remittance basis is gone.
Finance Act 2025 introduced the Foreign Income and Gains regime in its place. The headline shape, as set out in the Government’s Technical Note of 30 October 2024 and confirmed in the Act, is a four-year window for individuals who become UK-resident after a period of ten consecutive tax years of non-residence. During those four years, qualifying foreign income and gains can be claimed exempt from UK tax, regardless of whether the funds are brought into the UK. After the four years, the individual is taxed on worldwide income on the arising basis like any other UK resident.
The FIG regime is for people coming to the UK. It does not help an existing UK-resident non-dom; the previous remittance basis is genuinely gone for that person, subject only to specific transitional rules including the Temporary Repatriation Facility for previously unremitted foreign income and gains. ICAEW Tax Faculty and the Chartered Institute of Taxation have both, in their consultation responses through 2024 and early 2025, set out the practical edges of the transition — including a rebasing election available to qualifying former remittance-basis users (the precise pivot date depends on the individual’s deemed-domicile status and the FA 2025 transitional rules — in many cases 5 April 2017, but practitioners should verify on the facts), and the treatment of pre-arrival foreign income for FIG-eligible new arrivals. STEP’s UK technical committee has also published commentary on how the FIG regime interacts with offshore trust structures, an area where the Finance Act 2025 changes are particularly material.
For a UK business owner leaving for the UAE, the relevance of FIG is asymmetric. On the way out, FIG does nothing for you — it is for incoming residents. What matters on the way out is that the prior comfort of the remittance basis no longer exists for any UK-resident year you have left, so any year in which you are still UK-resident now exposes worldwide income on the arising basis. That sharpens the case for getting the residence position right at the point of departure rather than relying on a remittance-basis cushion that is no longer there.
Practical pitfalls when relocating to the UAE
The technical rules are one thing. The traps we see in practice are usually facts, not law. A clean exit on paper can be undermined by routine commercial decisions in the months after the move.
Continuing to do work for UK clients from the UAE
If you are personally performing services for UK clients while resident in the UAE, two issues arise. First, depending on the pattern, you may be creating a UK presence that risks UK source income or, in some cases, a UK permanent establishment of your UAE company. Second, your UK workdays may push you over the work-tie threshold or, in combination with other ties, over the day-count threshold for residence. It depends on your facts. We can run through it.
UK property income
Rental income from UK real estate remains UK-source and taxable in the UK regardless of where you are resident. Becoming non-resident does not switch this off. The Non-resident Landlord Scheme administered by HMRC governs how the rent is taxed and how letting agents withhold; this is administrative rather than transformative, but it is the place where new UAE residents most often discover that some income still needs to be reported in the UK.
The “available” UK home
Keeping a UK property that is technically available to you — not fully let on a recognised tenancy, not occupied by someone with a clear right of exclusion — can keep the accommodation tie alive even when you are sure you have moved. The tie runs on availability, not actual use beyond the one-night threshold. BDO and RSM both point to this in their private-client commentary as one of the most common reasons a non-residence position falls over under review.
Days back in the UK
The temptation, particularly in year one, is to come back regularly — board meetings, family, school holidays. Each visit is a midnight count. Combined with a family tie or accommodation tie, the day budget shrinks faster than people expect. We have seen business owners who were comfortably non-resident on a forecast basis become resident in practice because they did not track midnights against the table.

Where the company is managed and controlled
A UAE company managed in substance from the UK risks being treated as UK-resident for corporation tax under the central-management-and-control test, regardless of where it is incorporated. This is well-established in UK case law — covered in detail in UK management and control risks for UAE companies. For business owners who set up a UAE entity but continue to make all strategic decisions from a UK kitchen table, the company itself can become a UK taxpayer. Substance matters, and it is more than the licence.
How we approach this with you
Our role on a UK-to-UAE relocation runs across both sides. On the UAE side, we set up the entity for what the business actually does, build real substance in the UAE (the corresponding UAE tax-residency picture for UK business owners works alongside this) so the structure holds up to scrutiny, and support the operational reality — banking, residency visa, and the working-between-jurisdictions side — so the move is not just paperwork. On the UK side — Statutory Residence Test analysis, post-non-dom planning, exit timing, and ongoing UK return obligations — we work alongside experienced UK qualified tax advisers who handle that work directly. You don’t need to chase a separate UK adviser yourself; we coordinate both sides together. For HMRC enquiries, tribunal work, or complex offshore trust positions, the same UK advisers handle the technical work — so the depth is there when the facts need it.
What that looks like, in practice: we look at the UAE structure and the UK position together, not separately, because they affect each other. We are explicit about what is settled and what is judgement. We help you choose the right tax-year point to leave, and we build the substance so the SRT position holds up under HMRC review. After the move, we stay involved. The year-one and year-two questions — days back in the UK, and FIG if anyone in the family later moves to the UK — are where most business owners need an adviser still on the file.
If you are at the stage of working through the timing and the structure, we sit down with your specific facts — UK ties, UAE plans, family situation, business model — and work through it with you. There is no template that fits this question.

Frequently asked questions
Will I still owe UK tax if I move to the UAE?
It depends on whether you’re still considered UK tax-resident under the UK Statutory Residence Test in the year you’re asking about. If you’re non-resident for a UK tax year, the UK only taxes you on UK-source income (like UK rental property, UK employment, UK pensions) — your worldwide income from outside the UK is no longer in scope. If you’re still resident, the UK can tax your worldwide income unless you qualify for the new four-year FIG relief regime (covered below). The big change in April 2025 was that ‘domicile’ no longer matters for income tax or capital gains tax — what matters is residence status only.
How do I work out if I’m UK tax-resident in a given year?
HMRC’s Statutory Residence Test (SRT) is precise day-counting. Three tests are applied in order: an automatic non-resident test (if you spend few enough days in the UK, you’re automatically non-resident), an automatic resident test (if you spend enough days, you’re automatically resident), and a ‘sufficient ties’ test that weighs days against ties like a UK home available to live in, UK work, UK family, and UK days in prior years. The day thresholds depend on whether you’ve been UK-resident in any of the previous three tax years. The full SRT rules sit in HMRC’s RDR3 guidance and the underlying legislation in Finance Act 2013, Schedule 45.
What is the new FIG regime that replaced non-dom in 2025?
From 6 April 2025 the UK abolished the long-standing non-domicile regime and replaced it with a four-year Foreign Income and Gains (FIG) relief. New arrivers to the UK who haven’t been UK-resident in any of the 10 previous tax years can claim FIG relief for their first four years — meaning their non-UK income and gains aren’t taxed by the UK during that window. After year four, full UK tax applies on worldwide income whether you stay or leave. Existing non-doms who were already in the UK before April 2025 are subject to a separate transitional regime that’s outside the scope of this page.
How many days can I spend in the UK after I move to the UAE?
There’s no single answer — it depends on your specific UK ties and your prior UK residence history. The Statutory Residence Test sets day thresholds that change based on whether you’ve been UK-resident in any of the previous three tax years and how many ties you retain (UK home available to live in, UK work, UK family, UK days in prior years). For someone with no remaining UK ties who was UK-resident in the prior three years, around 90 days per year is a typical safe-harbour figure; for someone with significant UK ties, the threshold is lower. The ‘sufficient ties’ test is detailed and rests on individual facts — it’s not a number to guess at.
Do I get split-year treatment for the year I move?
Possibly — if you meet one of the eight ‘split-year cases’ set out in the SRT. The most common ones for UAE-bound business owners are Case 1 (you start full-time work overseas) and Case 3 (you cease to have a home in the UK). If you qualify for split-year, the tax year is split into a UK-resident part (everything before you leave) and a non-UK-resident part (after you leave), and the non-UK part is taxed only on UK-source income. The case you qualify for depends on the specific facts of your move, which is why pre-departure planning matters.
What about tax on UK property I keep after leaving?
UK rental income remains subject to UK income tax even after you become non-resident — you can elect into the Non-Resident Landlord Scheme to receive rents gross and file a UK tax return. Capital gains on UK residential property held by a non-resident are also taxed by the UK from April 2015 onwards (and from April 2019 for non-residential UK property). For UK shares held in a UK broker or ISA, the position depends on whether you continue contributing while non-resident (typically not allowed) and whether you sell while non-resident (usually outside UK CGT, with anti-avoidance exceptions for short absences).
What is the “management and control” rule for my UK company?
If you own a UK Limited Company and you become non-UK-resident, the company itself can also become non-UK-resident if its central management and control shifts overseas — for example, if all directors live abroad, board meetings happen abroad, and strategic decisions are made abroad. That sounds like a tidy outcome but it can trigger an exit charge in the UK on the company’s unrealised gains, plus immediate UK corporate tax consequences. Conversely, if the company stays UK-resident even though you’ve left, the company keeps paying UK corporation tax on its worldwide profits regardless of your personal residence. Either decision has real consequences and needs to be planned, not stumbled into.
Can I keep my UK ISA after I leave?
Yes — you can keep an existing ISA after you become non-UK-resident, and any growth and income inside the wrapper continues to be free of UK tax. What you can’t do is contribute to it while you’re non-resident; new contributions are only allowed for UK-resident taxpayers (and Crown employees abroad). When you become UK-resident again you can start contributing again. ISAs are usually not protected from tax in the country you move to — many countries (including the UAE) do not recognise the UK ISA wrapper for their domestic tax purposes. The UAE has no personal income tax, so the UAE side is moot. Other destinations may tax ISA growth as ordinary investment income.
Do I still need to file a UK tax return after I move?
Often, yes — for at least one or two more years. You’ll need to file a return for the year you leave (which is usually a split-year filing), and for any year afterwards in which you have UK-source income (UK rental, UK employment, UK pensions, certain UK savings income above the personal savings allowance, UK dividends above the dividend allowance, or UK capital gains on UK property). You also need to file if HMRC has issued you a notice to file. Once your only remaining UK exposure is UK-source investment income within the personal savings/dividend allowances and you have no UK rental, you can ask HMRC to remove you from self-assessment.
What about my UK pension?
UK pensions remain a UK matter even after you move to the UAE. UK private pension lump sums and income payments continue to be taxable in the UK at source under PAYE, unless a UK-UAE double-tax treaty provision applies (the UK-UAE treaty does cover pensions). UK State Pension can be claimed and paid abroad, and is uprated each year for UAE residents (this is not the case for all destinations — Australia, for example, has frozen UK State Pension uprating). Transferring a UK pension overseas is technically possible via a Qualifying Recognised Overseas Pension Scheme (QROPS) but the rules are complex and the tax consequences can be significant; this is its own piece of advice.
Can HMRC challenge my UAE residency?
HMRC doesn’t challenge your UAE residency directly — that’s between you and the UAE. What HMRC can challenge is your UK non-residency: whether your day-counting was accurate, whether your ties were correctly assessed, and whether the move was genuine rather than a paper exercise. The classic risk is someone who claims to have moved to the UAE on paper but in practice spends most of their time in the UK, has a UK home permanently available to them, and works for UK clients from UK premises. HMRC can and does open enquiries on these patterns. The practical defence is keeping clean records of UK days, having genuine UAE ties (real home, real work activity, real local life), and not creating a structure that looks artificial.
What’s the difference between UK domicile and UK residence?
Until April 2025 these were two completely separate concepts: residence determined where you paid tax day-to-day; domicile determined whether you got the non-dom remittance basis. From April 2025 the UK abolished domicile as a tax concept for income tax and capital gains tax — only residence matters for those two. Domicile still matters for inheritance tax (IHT), where the new rules use a ‘long-term resident’ test based on years of UK residence. The practical effect for UAE relocators: residence planning has become the central question; the old non-dom playbook no longer applies for income tax and CGT, but IHT planning is now its own distinct exercise.
What happens to my UK Limited Company after I leave?
Several options exist and the right one depends on what the company does. (1) Keep it as UK-resident, pay UK corporation tax on its worldwide profits, and run it remotely — fine for some service businesses, but you face UK CT on profits you may not need to. (2) Migrate the company’s tax residency overseas — possible by moving central management and control to the UAE, but triggers UK exit charges on unrealised gains and is not a casual move. (3) Wind the company up before you leave (members’ voluntary liquidation if solvent) and start fresh in the UAE — clean but requires the right exit timing for capital gains efficiency. (4) Sell the company, take the gain in the right tax year. Each route has materially different UK tax consequences; the choice should be made before the move, not after.
Can I become UK non-resident mid-year?
Yes, through the split-year cases mentioned above. Outside split-year, you’re either UK-resident for the whole tax year or non-resident for the whole tax year — there’s no general ‘partial year’ rule. Split-year is the exception that allows the year of arrival or departure to be split into a resident part and a non-resident part for income tax and capital gains tax purposes. Note that split-year does NOT apply for inheritance tax purposes — so if IHT exposure is part of your planning, the timing question is calculated separately.
What documentation should I keep to prove I left the UK?
HMRC enquiries (and your own future planning) get much easier with a clean evidence file. Keep copies of: your UAE Emirates ID and visa (showing arrival date), the UAE residency permit, the UAE tenancy agreement or property purchase, UAE utility bills in your name, your UAE bank statements showing day-to-day spending, work contracts or company licence showing UAE-based activity, flights in and out of the UK (use a day-count app from the day you leave), any UK property sale or new tenancy showing you no longer have a UK home available, and your UK Form P85 acknowledgement (the form you submit to HMRC to declare your leaving date). Six years of records is the practical minimum; longer if your move is complex.
