Dubai's combination of zero personal income tax, year-round sunshine, and a strategic position between East and West has made it one of the most popular destinations for UK leavers. But the tax picture has changed materially since 6 April 2025: the UK abolished the non-domicile regime, replaced it with the Foreign Income and Gains (FIG) regime, and moved Inheritance Tax onto a residence basis. The UAE, meanwhile, introduced 9% federal corporate tax in 2023.
To break UK tax residency you must satisfy HMRC’s Statutory Residence Test — typically by being present in the UK for fewer than 16 days (or up to 90 days with limited UK ties) in the relevant tax year. Even after leaving, the IHT ‘tail’ keeps you UK-domiciled for 3-5 years, and UK rental income remains taxable. Plan exit at least 12 months in advance for a clean break.
This 2026 guide sets out what UK residents actually need to know about leaving for Dubai — both the cleanly-favourable points and the new traps.
⚠️ Three Material Changes Since 2025
- Non-dom regime abolished — replaced by the FIG regime from 6 April 2025
- IHT on a residence basis — worldwide assets in scope if UK-resident for 10 of previous 20 years; IHT tail of up to 10 years after leaving
- UAE 9% corporate tax — in force since June 2023, affecting business owners who incorporate in the UAE
The UK Tax Position When You Leave
Three tests determine your UK tax liability after departure:
📋 Three Determining Tests
- Statutory Residence Test (SRT): decides whether you are UK tax resident in any given year. The SRT counts UK days, ties (family, accommodation, work, prior residence, country tie), and applies different rules to leavers and arrivers.
- Domicile (now largely defunct for tax): abolished as a connecting factor for income tax, CGT and IHT from 6 April 2025. Replaced by residence-based rules across the board.
- Long-Term Residence Test (for IHT): from 6 April 2025, you are within UK IHT on worldwide assets if you have been UK resident for at least 10 of the previous 20 tax years. After leaving, an IHT 'tail' lasts between 3 and 10 years depending on prior residence length.
Becoming Non-UK Resident: The Practical Steps
🏭 Five Practical Steps
- Notify HMRC: submit form P85 if you don't file Self Assessment, or use the residence pages (SA109) on your tax return.
- Limit UK days: the SRT day-count thresholds depend on your ties. Most former UK residents need to keep UK days well below 90 — often below 45.
- Sever ties where possible: selling or letting the UK home, closing UK accounts you no longer need, and ending UK employment all reduce your tie count.
- Establish UAE residency: secure a UAE residence visa (employment, property, or Golden Visa routes) and obtain a UAE Tax Residency Certificate from the Federal Tax Authority once you've been in the UAE long enough to qualify.
- Watch the 5-year temporary non-residence rule: if you return to the UK within five years, certain income and gains realised while abroad can be retrospectively taxed.
⚠️ The SRT Is More Complex Than Most People Expect
The number of UK days you can spend depends entirely on how many 'ties' you have — family, accommodation, substantive UK work, prior residence, and the country tie. Someone with four ties can spend only 15 UK days before being treated as UK resident. Someone with none can spend up to 182 days. Model your specific position for each tax year before committing to a move.
What UK Tax You May Still Pay After Leaving
Becoming non-resident eliminates UK tax on most non-UK income and gains — but several categories remain in scope:
| Income/Gain Type | UK Tax After Departure? | Notes |
|---|---|---|
| UK rental income | Yes — always | Non-Resident Landlord Scheme; UK Self Assessment required |
| UK employment income | Yes — for UK workdays | Days physically worked in the UK remain UK-taxable |
| CGT on UK land & property | Yes — 60-day rule | Report and pay within 60 days of completion |
| UK pensions | Usually — treaty may help | Generally taxable in UK at source; treaty relief may apply |
| UK dividends | Broadly exempt | Disregarded income rules apply; treaty interaction is technical |
| IHT on UK-situs assets | Yes — always | UK property and assets always in UK IHT scope |
| IHT on worldwide assets | During IHT tail | 3–10 years after leaving depending on prior UK residence length |
🏠 Non-Resident Landlords — A Common Trap
- UK rental income always remains UK-taxable — it cannot be sheltered by UAE residency
- Under the Non-Resident Landlord Scheme, letting agents must withhold 20% tax at source unless HMRC approves gross payment
- A UK Self Assessment return is still required annually
- Section 24 still applies — mortgage interest relief is still restricted to a 20% credit for individual non-resident landlords

The UAE Tax Position
The UAE has no personal income tax, no capital gains tax on individuals' personal assets, and no inheritance or estate tax. That core proposition is unchanged.
🇦🇪 UAE Federal Corporate Tax — Key Points
- 9% standard rate on business profits above AED 375,000 (approximately £82,000)
- 0% on profits up to AED 375,000
- Free Zone businesses meeting Qualifying Free Zone Person (QFZP) conditions can access a 0% rate on qualifying income — but the conditions are detailed and must be maintained
- Small Business Relief (treating revenue under AED 3 million as zero taxable income) is available only until tax periods ending 31 December 2026
⚠️ Free Zone '0%' Is Not Automatic
QFZP status requires the Free Zone entity to have adequate substance, derive qualifying income from qualifying activities, and not conduct 'excluded activities' (which include most financial services and real estate transactions with UAE residents). The 0% rate applies only to qualifying income — non-qualifying income is taxed at 9%. Proper structuring and annual compliance are essential.
The UK-UAE Double Tax Treaty
A double tax treaty between the UK and UAE has been in force since 2016. The treaty provides relief from double taxation on most types of income and gains by reference to which country has primary taxing rights.
📋 Key Treaty Points for UK Leavers
- Business profits of a UAE-resident company are taxable only in the UAE — unless there is a UK permanent establishment
- UK-source income for UAE tax residents may benefit from reduced withholding rates under the treaty
- A UAE Tax Residency Certificate (TRC) is required to claim treaty benefits — obtain this from the UAE Federal Tax Authority once you qualify
- The treaty does not override the UK's IHT long-term residence rules — the UK can still charge IHT on worldwide assets during the tail period
The IHT Tail — Planning Before You Leave
This is the most significant change for anyone who has been a long-term UK resident. From 6 April 2025, IHT is based on long-term UK residence — not domicile. If you have been UK-resident for 10 or more of the previous 20 tax years, your worldwide assets remain in scope for UK IHT for up to 10 years after departure.
⚠️ IHT Tail Lengths
- Resident for 10–13 years: IHT tail of 3 years after departure
- Resident for 14–16 years: IHT tail of 5 years
- Resident for 17–19 years: IHT tail of 8 years
- Resident for 20+ years: IHT tail of 10 years
Gifts made during the tail period are still Potentially Exempt Transfers — the seven-year clock runs from the date of the gift, not from departure.
✅ Key Takeaways — Moving to Dubai in 2026
- The SRT is technical and unforgiving — model your day count and ties for each tax year before you commit to a move
- From 6 April 2025, IHT depends on long-term residence, not domicile. Even after you leave, the UK can have IHT claims on worldwide assets for up to 10 years
- UK rental income, UK pensions and UK property gains remain UK-taxable after departure — these cannot be sheltered
- If you set up a UAE business, plan around UAE Federal Corporate Tax — particularly QFZP qualification for Free Zone companies, and the expiry of Small Business Relief in December 2026
- Get a UAE Tax Residency Certificate as soon as you qualify — it is essential for treaty claims and UAE tax residency proof
- If you may return within 5 years, structure income and disposals carefully to manage the temporary non-residence rules

Frequently Asked Questions
How many days can I spend in the UK after moving to Dubai?
The Statutory Residence Test (SRT) determines your UK tax residency based on day counts and UK ties. Most former UK residents need to keep UK days well below 90 — often below 45 — depending on how many ties they retain. The exact threshold depends on your specific ties including family, accommodation, work and prior residence.
Do I still pay UK tax after moving to Dubai?
Becoming non-UK resident eliminates UK tax on most non-UK income and gains, but several categories remain taxable: UK rental income, UK employment income for work performed in the UK, CGT on UK land and property (with 60-day reporting), UK pensions, and IHT on UK-situs assets. Worldwide assets remain in IHT scope for up to 10 years after leaving if you were a long-term UK resident.
What is the UAE corporate tax rate?
The UAE has a 9% federal corporate tax on business profits above AED 375,000 (approximately £82,000), introduced from June 2023. Profits up to AED 375,000 are taxed at 0%. Free Zone businesses meeting Qualifying Free Zone Person conditions can access 0% on qualifying income.
