If you're an investor, business owner, or expat weighing your options between the United Kingdom and the United Arab Emirates, understanding the United Kingdom United Arab Emirates capital gains tax comparison is essential. Capital gains tax (CGT) can significantly erode investment returns, and the difference between these two jurisdictions is nothing short of dramatic. In this comprehensive guide for the 2025/2026 tax year, we'll break down everything you need to know — from rates and thresholds to practical examples — so you can make informed financial decisions. Spoiler alert: when it comes to which country has lower capital gains tax, the answer is remarkably clear.
What Is Capital Gains Tax and Why Does It Matter?
Capital gains tax is a levy on the profit you make when you sell or dispose of an asset that has increased in value. This includes stocks, bonds, real estate (beyond your primary residence in many cases), business assets, and other investments.
For individuals planning cross-border investments or considering relocation, the CGT regime of a country can be a decisive factor. A favourable capital gains tax environment means more of your investment profits stay in your pocket, compounding your wealth over time.
Let's see how the United Kingdom and the United Arab Emirates stack up against each other.
Capital Gains Tax in the United Kingdom: Rates, Rules, and Thresholds (2025/2026)
The United Kingdom operates one of the more complex CGT systems among developed nations. Here's what you need to know for the 2025/2026 tax year.
CGT Rates for Individuals
Following significant changes introduced in the Autumn Budget 2024, the UK's CGT rates for the 2025/2026 tax year are as follows:
- Basic rate taxpayers: 18% on most assets (previously 10% before October 2024 changes)
- Higher and additional rate taxpayers: 24% on most assets (previously 20%)
- Residential property (not primary residence): 18% for basic rate taxpayers and 24% for higher rate taxpayers
- Business Asset Disposal Relief (formerly Entrepreneurs' Relief): The rate has increased to 14% for 2025/2026, rising to 18% from April 2026, with a lifetime limit of £1 million in qualifying gains
- Investors' Relief: Also aligned at 14% for 2025/2026, with a lifetime limit of £1 million
Annual Exempt Amount (Tax-Free Allowance)
For the 2025/2026 tax year, the UK's annual exempt amount remains at:
- £3,000 for individuals and personal representatives
- £1,500 for most trustees
This is a sharp decline from the £12,300 allowance that was in place as recently as 2022/2023, meaning far more investors are now caught in the CGT net.
Key Rules and Exemptions
- Primary Residence Relief (Private Residence Relief): Gains on your main home are typically exempt from CGT, provided certain conditions are met.
- ISA and Pension Wrappers: Gains within Individual Savings Accounts (ISAs) and pensions are exempt from CGT.
- Spousal Transfers: Transfers between spouses or civil partners are CGT-free, though this is under review.
- Losses: Capital losses can be offset against gains in the same tax year or carried forward to future years.
- Reporting Deadline: UK residents must report and pay CGT on residential property disposals within 60 days of completion. For other assets, CGT is reported via the Self Assessment tax return by 31 January following the end of the tax year.
Practical Example: UK Capital Gains Tax
Imagine you're a higher-rate taxpayer in the UK who sells shares in 2025/2026 for a profit of £50,000.
- Gain: £50,000
- Less annual exempt amount: £3,000
- Taxable gain: £47,000
- CGT at 24%: £11,280
That's a significant tax bill. Use our United Kingdom Capital gains tax Calculator to model your own scenario with precision.
Non-Residents and UK CGT
Non-UK residents are subject to CGT on disposals of:
- UK residential property
- UK commercial property (since April 2019)
- Assets used in a UK trade carried on through a UK branch or agency
- Interests in "property-rich" entities deriving 75% or more of their value from UK land
This means that even if you relocate to the UAE, your UK property investments may still attract UK CGT. More on this in the double taxation section below.
Capital Gains Tax in the United Arab Emirates: Rates and Rules (2025/2026)
The United Arab Emirates has long been celebrated as one of the world's most tax-friendly jurisdictions, and its approach to capital gains tax is the centrepiece of that reputation.
CGT Rates for Individuals
The answer here is simple and powerful:
- The UAE imposes 0% capital gains tax on individuals.
There is no personal capital gains tax in the United Arab Emirates. Whether you sell shares, real estate, cryptocurrency, or any other personal asset, individuals pay no CGT in the UAE for the 2025/2026 tax year.
Corporate Tax Considerations
The UAE introduced a federal corporate tax (CT) effective from June 2023, set at 9% on taxable profits exceeding AED 375,000 for businesses. Within this corporate tax framework:
- Capital gains realised by companies are generally included in taxable income and subject to the 9% corporate tax rate.
- Qualifying Free Zone entities may benefit from a 0% rate on qualifying income, which can include certain capital gains.
- Participation exemption: Gains from the disposal of a qualifying shareholding (generally ownership of 5% or more in a company held for at least 12 months meeting certain conditions) may be exempt from corporate tax.
However, for individuals — including sole proprietors below the corporate tax threshold — capital gains remain entirely untaxed.
Key Rules and Features
- No personal income tax: The UAE does not levy personal income tax, which means there is no additional layer of taxation on investment gains reported as income. Check this with our United Arab Emirates Income Tax Calculator.
- No annual filing requirement for individuals: Since there is no personal tax, there is no CGT filing obligation for individuals.
- Real estate gains: Property investors in the UAE pay no capital gains tax on property disposals, though there may be transfer fees (typically 4% of the property value in Dubai, split between buyer and seller) upon sale.
- No distinction between short-term and long-term gains: Since the rate is 0%, the holding period is irrelevant for individuals.
Practical Example: UAE Capital Gains Tax
Using the same scenario — you sell investments for a profit of £50,000 (or approximately AED 230,000):
- Gain: AED 230,000
- CGT at 0%: AED 0
- Total tax payable: Zero
The contrast could not be starker. You can verify this with our United Arab Emirates Capital gains tax Calculator.
Head-to-Head: United Kingdom vs United Arab Emirates Capital Gains Tax Comparison
Here's a direct comparison table for the 2025/2026 tax year:
| Feature | United Kingdom | United Arab Emirates |
|---|---|---|
| CGT on individuals (standard) | 18%–24% | 0% |
| CGT on residential property | 18%–24% | 0% (transfer fees may apply) |
| Annual exempt amount | £3,000 | N/A (no tax) |
| Business disposal relief | 14% (up to £1M lifetime) | 0% |
| Corporate capital gains | Included in corporation tax (25%) | 9% (with exemptions) |
| Filing requirement | Yes (Self Assessment / 60-day report) | No (for individuals) |
| Tax on crypto gains | 18%–24% | 0% |
| Non-resident obligations | Yes (on UK property/land) | No CGT obligations |
Bottom line: The UAE is the decisive winner on capital gains tax for individuals. The which country has lower capital gains tax question answers itself — the UAE charges nothing, while the UK can take up to 24% of your gains.
Double Taxation Treaties and Cross-Border Considerations
For expats and investors with ties to both countries, understanding the UK-UAE double taxation agreement (DTA) is critical.
The UK-UAE Double Taxation Agreement
The United Kingdom and the United Arab Emirates have a double taxation agreement in force. Key points relevant to capital gains include:
- Immovable property: Under the DTA, gains from the disposal of immovable property (real estate) may be taxed in the country where the property is situated. This means UK property sold by a UAE resident can still be taxed in the UK.
- Shares in property-rich companies: The UK retains the right to tax gains on shares deriving their value primarily from UK real estate.
- Other assets: For most other capital gains (shares, securities, movable assets), the DTA generally allocates taxing rights to the country of residence of the person making the disposal. Since the UAE doesn't tax these gains, a UAE resident disposing of non-UK assets would typically owe zero CGT in either country.
Key Cross-Border Scenarios
- UK resident selling UAE property: Subject to UK CGT at 18%–24% on the gain (less the £3,000 annual exemption). No UAE CGT applies.
- UAE resident selling UK property: Subject to UK non-resident CGT at 18%–24%. No UAE CGT applies. The DTA permits UK taxation.
- UAE resident selling global shares: 0% CGT in the UAE. No UK tax unless the shares are in UK property-rich entities.
- Relocating from UK to UAE: The UK has temporary non-residence rules. If you leave the UK, sell assets abroad, and return within five tax years, the gains may be taxed as if you never left. Plan carefully.
Common Mistakes and Misconceptions
- "Moving to Dubai means I never pay UK tax again." False. Non-residents still owe UK CGT on UK property and certain other UK assets. Always check your specific exposure.
- "The UAE has no taxes at all." While there's no personal income or capital gains tax, the UAE does have a 5% VAT, corporate tax (9%), excise duties, and municipal/transfer fees.
- "I can sell my UK home CGT-free after moving to the UAE." Private Residence Relief can be complex for emigrating individuals. The final period exemption and letting relief rules have specific conditions. You should seek professional advice.
- "Crypto is untaxed everywhere." While the UAE doesn't tax crypto gains for individuals, the UK treats cryptocurrency as a taxable asset. UK residents must report and pay CGT on crypto disposals.
Strategic Considerations: Who Benefits Most?
Investors and Portfolio Holders
If you hold a diversified portfolio of shares, funds, and securities, the UAE's 0% CGT regime offers an extraordinary advantage. A UK-based investor paying 24% on gains above a tiny £3,000 allowance faces a dramatically higher tax burden than a UAE-based counterpart.
Property Investors
Property investors need to think carefully. Buying and selling UAE property attracts no CGT (though there are transfer fees). Holding UK property from the UAE still exposes you to UK non-resident CGT. Consider using our United Kingdom Capital gains tax Calculator to estimate your exposure on any UK holdings.
Entrepreneurs and Business Owners
The UK's Business Asset Disposal Relief at 14% (rising to 18%) with a £1 million lifetime cap is less generous than it once was. UAE-based entrepreneurs selling business assets face no personal-level capital gains tax, though corporate-level disposals may attract the 9% CT (with important exemptions).
Expats and Relocators
For those considering relocation from the UK to the UAE, the tax savings on capital gains can be substantial — but the move must be genuine. HMRC scrutinises claims of non-residence, and the temporary non-residence anti-avoidance rules mean you typically need to remain outside the UK for at least five full tax years for capital gains to escape UK taxation. You should also consider your overall tax position using the United Kingdom Income Tax Calculator.
Frequently Asked Questions (FAQ)
Which country has lower capital gains tax, the UK or the UAE?
The United Arab Emirates has the lower capital gains tax — in fact, it charges 0% CGT for individuals. The UK charges between 18% and 24% depending on your income tax band and the type of asset.
Does the UAE have any capital gains tax at all?
For individuals, no. The UAE does not impose any capital gains tax on personal asset disposals. At the corporate level, gains may be subject to the 9% corporate tax, but exemptions (such as the participation exemption) can reduce or eliminate this.
Do I still pay UK capital gains tax if I move to the UAE?
Potentially, yes. UK non-residents are liable for CGT on disposals of UK real estate and interests in property-rich entities. Additionally, the UK's temporary non-residence rules may apply if you return within five tax years.
Is cryptocurrency taxed differently in the UK and UAE?
Yes. The UK treats cryptocurrency as a taxable asset — disposals are subject to CGT at 18%–24%. The UAE does not tax individual cryptocurrency gains.
Are there any tax-free allowances for capital gains in the UK?
Yes, but they are small. The annual exempt amount for 2025/2026 is just £3,000 for individuals. Gains within ISAs and pensions are also exempt.
How does the UK-UAE double taxation agreement affect capital gains?
The DTA allocates taxing rights: gains on immovable property are taxed where the property is located, while gains on most other assets are taxed in the country of residence. Since the UAE doesn't tax individual gains, UAE residents typically pay zero CGT on non-UK assets.
Conclusion: Key Takeaways
The United Kingdom United Arab Emirates capital gains tax comparison for 2025/2026 reveals one of the starkest contrasts in the global tax landscape:
- The UK charges CGT at 18%–24% on most assets, with a minimal £3,000 annual exemption, complex reporting requirements, and extended obligations for non-residents holding UK property.
- The UAE charges 0% capital gains tax on individuals — no rates, no thresholds, no filing, no complexity.
For investors, entrepreneurs, and expats, the UAE's zero-CGT environment is a powerful draw. However, cross-border considerations — particularly UK non-resident CGT rules and temporary non-residence provisions — mean that careful planning is essential.
