The United Arab Emirates is one of the most popular destinations for British professionals and executives relocating abroad, and it is easy to understand why. Dubai and Abu Dhabi offer zero personal income tax, no capital gains tax, and no wealth tax. If you have recently moved to the UAE, or are seriously considering it, the local tax picture is straightforward. The part that catches many British expats off guard is what HMRC still expects from them, even after they have left the UK.
How the UAE Determines Tax Residency
Since 1 March 2023, the UAE has operated a formal domestic tax residency framework under Cabinet Decision No. 85 of 2022. You will be considered a UAE tax resident if you meet any one of the following conditions: you have your usual or primary place of residence and your centre of financial and personal interests in the UAE; you are physically present in the UAE for 183 days or more during a consecutive twelve-month period; or you are physically present for 90 days or more during a twelve-month period and hold a valid UAE residence permit, alongside either a permanent place of residence or employment in the UAE.
For most British expats on employment visas in Dubai or Abu Dhabi, the 183-day test or the 90-day plus residence permit route will typically be met comfortably. The UAE will then issue a Tax Residency Certificate upon application, a document that becomes important when you need to demonstrate non-UK residence to HMRC.
What the UAE Does Not Tax
Confirmed by PwC’s Worldwide Tax Summaries (last reviewed March 2026), there is currently no personal income tax at either federal or Emirate level. There is no capital gains tax on individuals, no wealth tax, and no inheritance or estate tax. VAT was introduced in January 2018 at a standard rate of 5%, and applies to goods and services in the usual way, but it does not affect investment income or capital growth.
For non-GCC nationals (which covers the vast majority of British expats), there is no social security obligation either. End-of-service gratuity arrangements apply in most employment contexts, but these are employer obligations, not employee levies.
What HMRC Still Expects From You
This is where British expats often need a clearer picture. Leaving the UK is not simply a matter of boarding a flight and ceasing to file a UK tax return. HMRC applies the Statutory Residence Test (SRT) to determine whether you remain UK tax resident, and the rules have more moving parts than most people expect.
Under the SRT, you will be automatically non-UK resident in a tax year if you spend fewer than 16 days in the UK (if you were UK resident in any of the three preceding tax years) or fewer than 46 days (if you were not). If you do not meet an automatic overseas test, HMRC then counts your “UK ties” (family, accommodation, work, and time in the UK the previous year), and the day thresholds tighten accordingly. Spending 183 or more days in the UK in any tax year makes you automatically UK resident, regardless of where else you live.
The practical implication: many British expats in the UAE who make frequent return trips (for family, for business, or simply because Heathrow is a hub) find their day count creeps up. Careful monitoring of UK days, particularly in the first year of departure, matters.
Split-year treatment applies in the year of departure, meaning only your UK income and gains arising in the UK-resident portion of the year are taxed by HMRC. From the point you satisfy the SRT overseas conditions, UK-source income (rental income, dividends from UK holdings, interest from UK accounts) may still attract UK tax depending on the asset type and any applicable double tax treaty between the UK and UAE.
CRS and Information Exchange
The UAE is a signatory to the Common Reporting Standard (CRS) and exchanges financial account information with participating jurisdictions, including HMRC. If you hold bank accounts, brokerage accounts, or investment products in the UAE, information about those accounts will in due course be shared with the UK tax authority if you have a UK nexus. This does not create a tax liability in itself, but it does mean that offshore account holdings are visible to HMRC. Any undisclosed UK tax obligations do not disappear simply because assets are held in the Gulf.
Where an Investment Policy Wrapper Fits
British expats in the UAE who have accumulated savings (whether from UK pensions and ISAs they have left behind, or from UAE earnings they want to invest systematically) often encounter international investment products for the first time here. Dubai has one of the largest concentrations of expatriate financial advisers in the world, and names such as RL360, Hansard, Friends Provident International (FPI), and Utmost International are commonly mentioned in expat circles.
These products (variously described as portfolio bonds, investment-linked insurance policies, or international investment wrappers) are designed to hold a diversified investment portfolio inside a regulatory structure that sits outside any single country’s tax jurisdiction. The underlying policy is typically written out of a Crown Dependency such as the Isle of Man or Guernsey, both of which carry UK-adjacent legal and regulatory frameworks familiar to British investors. Some are written out of Ireland or Luxembourg for access to the EU regulatory umbrella.
In a zero-income-tax environment like the UAE, the income tax deferral benefit of a portfolio bond is less relevant than it would be in a high-tax jurisdiction. Where these structures become genuinely useful for British expats in Dubai is in a different set of circumstances: consolidating investments across currencies and asset classes into a single portable wrapper; maintaining the same structure if you move from the UAE to Singapore, or back to the UK; and most importantly, managing the UK inheritance tax exposure that follows British nationals wherever they live in the world.
If you have recently been presented with an illustration from a local IFA, or are trying to understand whether a portfolio bond is the right structure for your situation, the cost model and open-architecture flexibility of the product matters as much as the brand name on the cover.
