How a UK resident should read a Dubai acquisition

The UK tax treatment of overseas residential property has changed more in the past decade than in the previous fifty years, and the changes have almost all moved in one direction. A Dubai holding does not escape UK taxation. What it does is remove an entire layer of local cost and local tax, while leaving the UK layer intact — and the arithmetic of that trade is what this section sets out.

Section 24 follows you overseas

The restriction on finance cost relief introduced by section 24 of the Finance (No. 2) Act 2015 is widely understood as a UK buy-to-let measure. It is not. It applies to a residential property business, and a UK resident letting a property in Dubai is carrying on a residential property business for these purposes. Mortgage interest is therefore no longer deductible from rental profit. Relief is given instead as a basic rate tax reducer at 20 percent, fully phased in since April 2020.

For an additional rate taxpayer this is the single most consequential number in the model. Interest that would once have reduced taxable profit pound for pound now generates relief at 20 percent against a 45 percent marginal rate. The effect is that a geared overseas holding can show an accounting profit close to nil and still produce a UK tax liability. Any yield projection that deducts interest before tax is overstating the return to a higher or additional rate taxpayer, and a great many circulating in this market do exactly that.

The corollary is that gearing is far less attractive to a UK resident here than the headline mortgage rate suggests, and that an unleveraged or lightly leveraged position often produces a better after-tax outcome. That is an unusual conclusion in a market that sells leverage, and it is the honest one.

Reporting, and the end of the remittance basis

Overseas property income is reported on the foreign pages of the self-assessment return. Rent is taxable in the year it arises, whether or not it is brought into the United Kingdom — and the former remittance basis, which allowed certain non-domiciled residents to be taxed only on remitted foreign income, was abolished from April 2025 and replaced by a residence-based regime. New arrivals with a sufficient period of prior non-residence receive a time-limited exemption on foreign income and gains; established residents do not. Anyone whose Dubai plan was built on the old basis needs it re-examined rather than assumed.

Capital gains, and the SDLT point nobody mentions

A UK resident remains within the charge to UK capital gains tax on the disposal of a Dubai property, at residential rates, with no UAE tax to credit against it. What is genuinely eliminated is the local layer: no annual property tax, no second-home surcharge, no ATED equivalent, and a single 4 percent transfer fee in place of a tiered stamp duty.

One point deserves emphasis because it is almost never raised. Owning property overseas can increase the stamp duty land tax payable on a subsequent UK purchase. The higher rates of stamp duty land tax for additional dwellings test worldwide property ownership, not UK ownership. A client who buys in Dubai and later buys a home in England may find the Dubai holding has pushed the English purchase into the surcharge. That is a foreseeable and quantifiable cost, and it should be modelled at the outset rather than discovered at the second completion.

The treaty, and the sleeper issue

The United Kingdom and the United Arab Emirates have a double taxation convention in force. Its practical effect on rental income is modest, since relief from double taxation presupposes tax in both states and the UAE imposes none. Its value lies in the certainty it provides on residence, permanent establishment and the treatment of gains.

The sleeper issue is inheritance tax. UK inheritance tax exposure now turns on long-term residence rather than domicile following the April 2025 reforms, and a person within scope is exposed on their worldwide estate — a Dubai property included, at 40 percent above the available thresholds, notwithstanding that the UAE levies no estate tax. For a client acquiring a substantial Dubai asset, this is frequently the largest number in the whole analysis and the one least often modelled.

The case that survives all of the above

Dubai residential values average approximately AED 1,759 per square foot, roughly 47 percent above 2022 levels, with gross yields between 6 and 10 percent against the 2 to 4 percent typical of prime London. A qualifying holding of AED 2,000,000 or more opens the ten-year renewable Golden Visa including spouse and children. Even after UK taxation at additional rates, the gross yield differential is wide enough that the position frequently still works — but it works on the unleveraged arithmetic far more often than on the geared version.
