If you're an investor, property owner, or expat weighing your options between two of Europe's largest economies, understanding the United Kingdom France capital gains tax comparison is essential. Capital gains tax (CGT) can significantly impact your net returns when you sell assets such as shares, property, or business interests—and the rules in the UK and France differ in important ways.
In this comprehensive guide, we compare which country has lower capital gains tax for the 2025/2026 tax year, walk through real-world examples, and highlight the pitfalls that catch taxpayers off guard. Whether you're a resident of either country, a cross-border investor, or considering relocation, this article will give you the clarity you need.
How Capital Gains Tax Works: A Quick Overview
Before diving into the comparison, let's establish the basics.
Capital gains tax is levied on the profit you make when you dispose of (sell, gift, or transfer) an asset that has increased in value. Both the UK and France tax these gains, but they do so using fundamentally different mechanisms:
- United Kingdom: CGT is a standalone tax charged at specific flat rates that depend on the type of asset and the taxpayer's income tax band.
- France: Capital gains can be subject to a flat-rate levy (prélèvement forfaitaire unique, or PFU) or, in some cases, integrated into the progressive income tax scale, plus social charges (prélèvements sociaux).
This structural difference is the first clue that a simple rate-versus-rate comparison doesn't tell the whole story.
United Kingdom Capital Gains Tax Rates and Rules (2025/2026)
The UK tax year runs from 6 April 2025 to 5 April 2026. Here are the key CGT parameters.
CGT Rates
Following the changes announced in Autumn Budget 2024 and taking effect from April 2025, UK CGT rates are:
| Taxpayer Band | Standard Assets (shares, etc.) | Residential Property (non-PPR) |
|---|---|---|
| Basic-rate taxpayer | 18% | 18% |
| Higher/additional-rate taxpayer | 24% | 24% |
Note that the previous lower rates of 10% and 20% for non-property assets were increased in the October 2024 budget. From April 2025, the rates are unified at 18% (basic rate) and 24% (higher/additional rate) for all asset types.
Annual Exempt Amount (Tax-Free Allowance)
For 2025/2026, the annual exempt amount remains at:
- £3,000 for individuals
- £1,500 for most trustees
This means the first £3,000 of capital gains in the tax year is completely tax-free. While this allowance has been dramatically reduced from the £12,300 it stood at just two years ago, it still provides a small buffer.
Key Exemptions and Reliefs
- Principal Private Residence (PPR) Relief: Gains on your main home are generally exempt from CGT.
- Business Asset Disposal Relief (BADR): Qualifying business owners can benefit from a reduced 14% rate (rising to 18% from April 2026) on up to £1 million of lifetime gains.
- ISAs and Pensions: Gains within Individual Savings Accounts and registered pension schemes are fully exempt.
- Spousal transfers: Transfers between spouses/civil partners are made on a no-gain, no-loss basis.

France Capital Gains Tax Rates and Rules (2025/2026)
France's tax year follows the calendar year (January–December). The rates below apply for the 2025 income year (declared in 2026).
The Flat Tax (Prélèvement Forfaitaire Unique – PFU)
France's default regime for most capital gains on movable assets (shares, bonds, cryptocurrency, etc.) is the PFU, commonly called the flat tax:
| Component | Rate |
|---|---|
| Income tax portion | 12.8% |
| Social charges (prélèvements sociaux) | 17.2% |
| Total PFU | 30% |
So a French resident selling shares at a profit faces a combined 30% flat tax by default.
Option for Progressive Scale (Barème Progressif)
Taxpayers can elect to have their capital gains taxed under the progressive income tax scale instead of the PFU. This may be advantageous for lower-income taxpayers because:
- Marginal rates start at 0% (up to €11,497 for 2025) and rise through 11%, 30%, 41%, to 45%.
- A partial CSG deduction (6.8% of the 9.2% CSG is deductible) becomes available.
- Enhanced allowances for holding period may apply to shares acquired before 2018.
However, the 17.2% social charges always apply regardless of which option you choose.
Capital Gains on Real Estate (Plus-Values Immobilières)
France treats property gains differently from financial gains:
- Tax rate: 19% income tax + 17.2% social charges = 36.2% base rate.
- Surtax: An additional surtax of 2%–6% applies on gains exceeding €50,000.
- Holding-period allowances: The taxable gain is progressively reduced the longer you've held the property—full income tax exemption after 22 years of ownership, and full social charges exemption after 30 years.
- Principal residence exemption (résidence principale): Like the UK, gains on your main home are fully exempt.
Other Notable Features
- Departure tax (exit tax): France may tax unrealised gains when a taxpayer with a significant portfolio (>€800,000 or >50% in a company) leaves France, although payment can be deferred within the EU.
- PEA (Plan d'Épargne en Actions): A tax-advantaged share savings plan that can shelter gains from CGT after a five-year holding period (social charges still apply).

Head-to-Head: Which Country Has Lower Capital Gains Tax?
Now for the question everyone asks: which country has lower capital gains tax, the UK or France? The answer depends on the type of asset, your income level, and how long you've held the investment.
Comparison on Financial Assets (Shares, Funds, Crypto)
| Factor | United Kingdom | France |
|---|---|---|
| Top effective rate | 24% | 30% (PFU) |
| Lower-income rate | 18% | 30% (PFU) or potentially lower via progressive scale |
| Tax-free allowance | £3,000 per year | None under PFU |
| Tax-advantaged wrappers | ISAs (unlimited CGT exemption) | PEA (exempt after 5 years, social charges still apply) |
Verdict on financial assets: For most investors, the UK is cheaper. Even at the higher 24% rate, the UK undercuts France's 30% flat tax by 6 percentage points. When you add the £3,000 annual exemption and the ISA regime (where gains are 0%), the UK advantage widens further. French taxpayers in low income brackets who opt for the progressive scale could narrow the gap, but the 17.2% social charges create a high floor.
Comparison on Residential Property
| Factor | United Kingdom | France |
|---|---|---|
| Top effective rate (non-main-home) | 24% | 36.2% (+ up to 6% surtax) |
| Main home exemption | Yes (PPR relief) | Yes (résidence principale) |
| Holding-period relief | None | Yes—full exemption after 22/30 years |
| Tax-free allowance | £3,000 | None (but holding-period taper) |
Verdict on property: In the short to medium term, the UK wins again—24% versus 36.2% (or more). However, France's generous holding-period taper means that if you hold a property for over 22 years, the income tax component disappears entirely. At 30 years, social charges also vanish. For long-term property holders, France can actually result in zero CGT, a position the UK cannot match.
Practical Example: Selling Shares Worth £100,000 / €116,000
Let's say you purchased shares for £50,000 (approximately €58,000) and sell them for £100,000 (approximately €116,000), realising a £50,000 / €58,000 gain.
In the UK (higher-rate taxpayer):
- Gain: £50,000
- Less annual exemption: £3,000
- Taxable gain: £47,000
- CGT at 24%: £11,280
In France (PFU):
- Gain: €58,000
- No annual exemption under PFU
- Taxable gain: €58,000
- PFU at 30%: €17,400 (≈ £15,000)
Result: The UK taxpayer pays roughly £3,700 less in this scenario. Even a UK basic-rate taxpayer (18% rate) would pay only £8,460—still significantly below the French figure.

Practical Example: Selling a Second Home After 25 Years
Now consider a rental property bought for €200,000 and sold for €400,000 (gain of €200,000) after 25 years of ownership.
In France:
- Income tax (19%): Fully exempt after 22 years → €0
- Social charges (17.2%): Taper of 1.65% per year from year 6–21, then 1.60% for year 22, then 9% per year from year 23–30. After 25 years, the social charges taper provides a significant reduction (approximately 82.5% reduction), leaving roughly €7,000 in social charges.
- Approximate total: ~€7,000
In the UK:
- Gain: £172,000 (equivalent)
- Less annual exemption: £3,000
- CGT at 24%: £40,560
Result: For very long-term property holdings, France is dramatically cheaper thanks to its taper relief. This is a critical consideration for anyone planning a decades-long property investment.
Double Taxation: What If You Have Ties to Both Countries?
Many readers of this United Kingdom France capital gains tax comparison have connections to both countries—perhaps owning property in France while being UK tax resident, or vice versa.
The UK-France Double Taxation Agreement (DTA)
The UK and France have a comprehensive Double Taxation Convention that covers capital gains. Key provisions include:
- Immovable property (real estate): Gains on property situated in one country may be taxed by that country, even if the seller is resident in the other. The resident country then provides relief (usually a credit) to avoid double taxation.
- Shares and securities: Generally taxable only in the country of residence of the seller.
- Business assets / permanent establishments: Gains attributable to a PE in one country can be taxed there.
Common Pitfall: Assuming You Only Pay Tax Once
A frequent misconception is that the DTA means you automatically pay the lower of the two rates. In reality, you typically pay the full rate in the source country and then claim a tax credit in your residence country. If your residence country's rate is higher, you pay the difference. If it's lower, you generally don't get a refund of the excess foreign tax.
Example: A UK resident sells a French holiday home. France taxes the gain at 19% + 17.2% social charges. The UK also wants CGT at 24%. Under the DTA, the UK provides a credit for the French income tax portion (19%), but not for French social charges (which the UK does not consider a creditable tax for many purposes post-Brexit). The result can be a combined effective rate that exceeds both countries' standalone rates.
Tip: Social charges (prélèvements sociaux) remain a grey area for credit purposes. UK residents with French property should seek specialist cross-border tax advice.

Non-Residents: How Each Country Taxes Overseas Sellers
UK Rules for Non-Residents
Since April 2015, non-residents are liable to UK CGT on disposals of UK residential property. Since April 2019, this was extended to all UK land and property (commercial and residential). Non-residents selling UK shares are generally not subject to UK CGT unless the shares derive at least 75% of their value from UK land.
- Rates for non-residents mirror those for residents (18%/24%).
- Non-residents must report and pay CGT on UK property within 60 days of completion.
French Rules for Non-Residents
Non-residents selling French property are subject to the standard 19% income tax rate on the gain, plus a potential surtax on large gains. However, the social charges situation differs:
- EU/EEA residents: Subject to 7.5% prélèvement de solidarité instead of the full 17.2% social charges (a significant saving).
- Non-EU residents (including UK residents post-Brexit): Subject to the full 17.2% social charges.
This is an important post-Brexit consequence: UK residents selling French property now pay 17.2% in social charges rather than the 7.5% that applied when the UK was in the EU, adding roughly 10 percentage points to the effective rate.
Frequently Asked Questions
Is crypto taxed differently in the UK and France?
In the UK, cryptocurrency gains are taxed under the normal CGT regime (18%/24%) with the £3,000 annual exemption. In France, crypto gains are taxed under the PFU at 30% for occasional traders, or as bénéfices industriels et commerciaux (BIC) for habitual traders. France does offer a €305 annual exemption on total disposal proceeds (not gains) for crypto.
Do I get inflation adjustment in either country?
Neither the UK nor France currently offers formal indexation relief for capital gains. The UK abolished indexation for individuals in 2008 (it remains for companies). France's holding-period taper for property is based on duration of ownership, not inflation.
Which country is better for a buy-to-let investor?
For short and medium-term buy-to-let investments (under 15 years), the UK's 24% rate is considerably lower than France's 36.2%+. For very long-term holdings (22+ years), France's taper relief can reduce the tax to near zero. Your choice should also factor in rental income taxation, wealth tax (IFI in France), and transaction costs.
Can I use losses to offset gains?
Yes, in both countries:
- UK: Capital losses can be offset against gains in the same year, and unused losses can be carried forward indefinitely.
- France: Under the PFU, loss offsetting is available against gains of the same type, with a 10-year carry-forward period.
Key Takeaways and Next Steps
Here's a summary of the United Kingdom France capital gains tax comparison for 2025/2026:
- For most asset types and holding periods, the UK has lower capital gains tax rates (18–24%) compared to France (30% PFU or 36.2% on property).
- France rewards patience: Its holding-period taper for property can eliminate CGT entirely after 22–30 years—something the UK doesn't offer.
- The UK's annual exempt amount (£3,000) provides a small but useful tax-free buffer that France lacks under the PFU.
- Tax-advantaged wrappers matter: UK ISAs and French PEAs can shelter significant gains from CGT, making the wrapper choice as important as the headline rate.
- Cross-border situations are complex: The UK-France DTA helps avoid double taxation, but post-Brexit social charges can create unexpected costs for UK residents with French assets.
- Non-residents beware: Both countries tax non-resident property sellers, and post-Brexit UK residents face higher French social charges.
