Capital gains tax (CGT) can significantly impact your net returns on property sales, share disposals, and other asset transactions — and the difference between these two countries could hardly be more striking.
In this comprehensive capital gains tax comparison for the 2025/2026 tax year, we break down the rates, exemptions, filing obligations, and practical implications for both residents and non-residents in each country. Whether you're relocating, investing internationally, or simply exploring your options, this tax comparison United Kingdom United Arab Emirates guide will help you make informed decisions.
What Is Capital Gains Tax? A Quick Overview
Capital gains tax is a tax levied on the profit (or "gain") you make when you sell or dispose of an asset that has increased in value. Not all countries impose this tax, and among those that do, the rates and rules vary enormously.
- Taxable events typically include selling shares, investment funds, property, business assets, and certain personal possessions.
- The gain is usually calculated as the difference between the disposal price and the original acquisition cost (with certain allowable deductions).
- Some jurisdictions offer annual exemptions, reduced rates for long-held assets, or complete exemptions for certain asset classes.
The UK and the UAE sit at opposite ends of the CGT spectrum, making this comparison especially relevant for anyone with financial ties to both nations.
Capital Gains Tax in the United Kingdom: 2025/2026 Rates and Rules
The United Kingdom has a well-established capital gains tax regime administered by HM Revenue & Customs (HMRC). For the 2025/2026 tax year (6 April 2025 to 5 April 2026), several important changes have taken effect following the Autumn Budget 2024 announcements.
Who Pays UK Capital Gains Tax?
- UK residents are liable to CGT on gains from worldwide assets.
- Non-UK residents are generally only liable on gains from UK residential property (and certain other UK land and property interests), as well as gains from assets used in a UK trade carried on through a UK branch or agency.
- Temporary non-residents who return to the UK within five years may still be liable for gains made during their absence.
UK CGT Rates for 2025/2026
Following the increases announced in October 2024, the main UK CGT rates for individuals in 2025/2026 are:
| Asset Type | Basic Rate Taxpayer | Higher/Additional Rate Taxpayer |
|---|---|---|
| Residential property | 18% | 24% |
| Other assets (shares, etc.) | 18% | 24% |
Key point: The lower rate of 10% for non-property assets was increased to 18% from 30 October 2024, and the higher rate was raised from 20% to 24%. Residential property rates remain unchanged at 18% and 24%. This means that from 2025/2026 onwards, the same rates apply across all asset types.
Annual Exempt Amount (AEA)
For 2025/2026, the UK annual exempt amount for individuals is £3,000. This means you can realise up to £3,000 in capital gains each tax year without paying any CGT. This threshold was significantly reduced from £12,300 in 2022/2023, making tax planning more important than ever.
- Married couples and civil partners each receive their own £3,000 allowance.
- Trusts have a reduced allowance of £1,500.
Key Reliefs and Exemptions in the UK
- Principal Private Residence Relief (PPR): Gains on the sale of your main home are typically fully exempt from CGT, provided certain conditions are met.
- Business Asset Disposal Relief (BADR): Formerly known as Entrepreneurs' Relief, this provides a reduced 14% rate on qualifying business disposals up to a lifetime limit of £1 million. Note that this rate is set to rise to 18% from April 2026.
- Investors' Relief: A 14% rate on qualifying shares in unlisted trading companies, subject to a £10 million lifetime limit (also rising to 18% from April 2026).
- ISA and pension exemptions: Gains within Individual Savings Accounts (ISAs) and pensions are exempt from CGT.
- Transfers between spouses/civil partners: These are generally CGT-free (though rules have been tightened for separating couples).
Reporting and Payment Deadlines
- UK residential property disposals: A CGT return must be filed and any tax paid within 60 days of completion.
- Other gains: Reported through the annual Self Assessment tax return, with payment due by 31 January following the end of the tax year.

Capital Gains Tax in the United Arab Emirates: 2025/2026 Rules
The United Arab Emirates has long been renowned as a tax-friendly jurisdiction, and this reputation largely holds true for capital gains — but with some important nuances following the introduction of corporate tax in 2023.
Individuals: No Capital Gains Tax
The UAE does not impose any capital gains tax on individuals. This applies regardless of:
- The type of asset (property, shares, gold, cryptocurrency, etc.)
- The size of the gain
- Whether the individual is a UAE resident or non-resident
- The holding period of the asset
This zero-tax treatment on personal capital gains is one of the primary reasons the UAE attracts high-net-worth individuals, investors, and entrepreneurs from around the world. There is no annual filing requirement for individuals in relation to capital gains, and no exemption thresholds to track — because there is simply no tax to pay.
Businesses: Corporate Tax Considerations
Since 1 June 2023, the UAE has imposed a federal corporate tax at a rate of 9% on business profits exceeding AED 375,000. Capital gains realised by businesses generally form part of taxable income under this regime. However, there are significant exemptions:
- Qualifying participation exemption: Capital gains from the disposal of qualifying shareholdings (generally ownership of 5% or more in a company for at least 12 months) may be exempt from corporate tax.
- Free zone businesses: Qualifying Free Zone Persons may benefit from a 0% corporate tax rate on qualifying income, which can include certain capital gains.
- Small business relief: Businesses with revenues below AED 3 million may elect for simplified treatment.
For most individual investors and personal asset holders, the UAE remains a zero capital gains tax environment in 2025/2026.

Practical Examples: How the Tax Difference Plays Out
Let's look at a few scenarios to illustrate the United Kingdom vs United Arab Emirates capital gains tax impact in real terms.
Example 1: Selling Shares Worth £100,000 Gain
In the UK (higher rate taxpayer):
- Gain: £100,000
- Annual exempt amount: £3,000
- Taxable gain: £97,000
- CGT at 24%: £23,280
In the UAE:
- Gain: £100,000 (or equivalent in AED)
- CGT: £0
Difference: £23,280 — a substantial amount that could be reinvested.
Example 2: Selling a Buy-to-Let Property With a £250,000 Gain
In the UK (higher rate taxpayer):
- Gain: £250,000
- Annual exempt amount: £3,000
- Taxable gain: £247,000
- CGT at 24%: £59,280
- Plus, a 60-day reporting and payment deadline applies.
In the UAE:
- Gain: £250,000 equivalent
- CGT: £0
- No reporting required.
Example 3: Business Owner Selling a Qualifying Business for £500,000 Gain
In the UK (using BADR):
- Gain: £500,000
- Annual exempt amount: £3,000
- Taxable gain: £497,000
- CGT at 14% (BADR rate): £69,580
In the UAE:
- Gain: £500,000 equivalent
- Individual CGT: £0
These examples demonstrate why asset structuring and residency planning are critical considerations for internationally mobile individuals.

Double Taxation Treaties and Cross-Border Considerations
For individuals and businesses with connections to both the UK and the UAE, the UK-UAE Double Taxation Agreement (DTA) is a critical piece of the puzzle.
Key Provisions of the UK-UAE DTA
- The UK and UAE signed a comprehensive Double Taxation Convention, which has been updated over the years.
- Under most DTAs, capital gains on immovable property (real estate) are taxable in the country where the property is located. So a UAE resident selling UK property will still owe UK CGT on that gain.
- Gains on shares are generally taxable only in the country of residence of the seller — meaning a UAE resident selling non-UK shares would owe no CGT anywhere.
- The DTA provides mechanisms to avoid double taxation where income or gains might otherwise be taxed in both jurisdictions.
Common Cross-Border Scenarios
- UK resident with UAE investments: Any gains are subject to UK CGT at the standard rates, regardless of where the assets are located. The zero UAE rate does not help if you are UK-resident.
- UAE resident with UK property: You will owe UK CGT on any gain from UK residential property. The 60-day reporting rule applies.
- Relocating from the UK to the UAE: If you become non-UK resident, you generally escape UK CGT on most assets (except UK property). However, the temporary non-residence rules mean that if you return to the UK within five complete tax years, gains realised while abroad may be taxed as if you had never left.
- UAE resident with no UK ties: No capital gains tax exposure in either country.
Important Pitfalls to Avoid
- Assuming UAE residency alone eliminates UK tax: If you retain UK property or return to the UK within five years, liabilities can arise.
- Ignoring the 60-day reporting rule: Non-residents selling UK property must report and pay within 60 days — late filing triggers penalties and interest.
- Overlooking deemed domicile rules: Long-term UK residents who are not UK-domiciled may still face CGT on worldwide gains after 15 years of UK residency under the deemed domicile rules (noting that the non-dom regime is undergoing significant reform from April 2025).
Frequently Asked Questions: UK vs UAE Capital Gains Tax
Is there really no capital gains tax in the UAE for individuals?
Correct. As of 2025/2026, the UAE does not impose any capital gains tax on individuals. There is no personal income tax, no capital gains tax, and no wealth tax for individual residents or non-residents.
Will the UAE introduce capital gains tax in the future?
While the introduction of corporate tax in 2023 and VAT in 2018 suggest the UAE's tax landscape is evolving, there are currently no announced plans to introduce personal capital gains tax. However, it is always wise to monitor developments.
Can I avoid UK CGT by moving to the UAE?
Potentially, but it is not automatic. You must become genuinely non-UK resident under the Statutory Residence Test (SRT) and remain so for at least five full tax years. UK property gains will still be taxable in the UK regardless of your residence. Professional advice is essential before making such a move.
How does the UK's non-dom reform affect capital gains?
From April 2025, the UK is transitioning away from the traditional remittance basis for non-domiciled individuals. New arrivals to the UK may benefit from a four-year Foreign Income and Gains (FIG) regime, during which foreign capital gains may be exempt from UK tax. After four years, worldwide gains become fully taxable. This is a significant change that affects expats and internationally mobile individuals.
Do I need to report capital gains in the UAE?
No. Individuals in the UAE have no personal tax return filing obligation. Businesses subject to UAE corporate tax must include capital gains in their corporate tax returns where applicable.
What about crypto gains?
In the UK, cryptocurrency gains are subject to CGT at the standard rates (18%/24%). In the UAE, individual crypto gains are not taxed. This makes the UAE particularly attractive for crypto investors.

Key Takeaways and Next Steps
The capital gains tax comparison between the United Kingdom and the United Arab Emirates reveals a dramatic contrast:
- The UK imposes CGT at rates of 18%–24% on individuals, with a modest £3,000 annual exemption and strict reporting requirements. Reliefs exist for primary residences and qualifying business disposals, but the overall tax burden on capital gains is significant and increasing.
- The UAE levies zero capital gains tax on individuals, with no filing or reporting requirements. Even for businesses, the 9% corporate tax rate comes with generous exemptions for qualifying shareholdings and Free Zone entities.
For investors and expats, the implications are clear:
- UK-based investors should maximise available reliefs (PPR, BADR, ISAs, pensions) and use the annual exempt amount strategically.
- UAE-based individuals benefit from a highly favourable tax environment for all types of capital gains.
- Cross-border individuals must carefully manage residency status, understand the UK-UAE DTA, and be aware of the temporary non-residence anti-avoidance rules.
- Anyone considering relocation should seek specialist advice before acting — the tax savings can be substantial, but the rules are complex.
