If you're considering moving to France taxes should be high on your research list — and capital gains tax (CGT) is one of the areas that catches expats off guard most often. France's tax system is comprehensive, sophisticated, and notably different from what you may be accustomed to in the UK, US, or elsewhere. Understanding expat capital gains tax France rules before you arrive can save you thousands of euros and prevent unpleasant surprises at filing time.

This France expat tax guide walks you through everything you need to know about capital gains tax as an expatriate living in — or moving to — France for the 2025/2026 tax year. We'll cover real estate gains, securities gains, social charges, key exemptions, double taxation treaties, and common mistakes to avoid.

How France Defines Tax Residency — And Why It Matters

Before diving into capital gains tax rates and rules, you need to understand whether France considers you a tax resident. Your residency status fundamentally determines how your capital gains are taxed.

Under French tax law (Article 4 B of the Code Général des Impôts), you are considered a French tax resident if any of the following apply:

  • Your principal home (foyer) is in France, meaning your family or habitual place of living is located there.
  • You spend more than 183 days per year in France (not necessarily consecutively).
  • Your principal professional activity is exercised in France.
  • Your centre of economic interests is in France — for example, the majority of your investments, business interests, or income sources.

If you qualify as a French tax resident, you are subject to French tax on your worldwide capital gains — including gains from selling property or securities abroad. Non-residents, by contrast, are generally only taxed on French-source capital gains (such as selling French real estate).

The Arrival Year: Split Residency

The year you move to France can create a split-residency situation. France taxes you as a resident from the date you establish residency. Any capital gains realised before your arrival may still be taxed in your country of origin. Double taxation treaties (discussed below) help resolve overlapping claims.

Capital Gains Tax on Real Estate (Plus-Values Immobilières)

Real estate capital gains tax is one of the most significant tax considerations for expats in France, whether you're selling a French property or disposing of real estate back home.

Tax Rates for 2025/2026

For French tax residents, the standard rate on real estate capital gains is:

  • 19% flat income tax on the net gain
  • 17.2% social charges (prélèvements sociaux), bringing the combined effective rate to 36.2%

For non-residents (EU/EEA citizens), the rate is also 19% plus social charges at 17.2%. Non-EU/EEA non-residents may face a rate of 33.33% instead of 19%, depending on their country of residence and applicable tax treaties.

Additionally, a surtax applies to large gains:

Net Taxable Gain Surtax Rate
Up to €50,000 0%
€50,001 – €100,000 2%
€100,001 – €150,000 3%
€150,001 – €200,000 4%
€200,001 – €250,000 5%
Over €250,000 6%

Calculating the Taxable Gain

The taxable gain is calculated as:

  1. Selling price minus allowable selling costs (e.g., estate agent fees, diagnostics)
  2. Minus the acquisition price (purchase price plus notarial fees — either actual or a flat 7.5% of the purchase price)
  3. Minus improvement works (either actual documented costs or a flat 15% of the purchase price if you've held the property for more than 5 years)

The resulting gross gain is then reduced by holding period allowances (abattements), which are crucial for long-term property owners.

Holding Period Allowances

France provides generous tapering relief based on how long you've owned the property:

For income tax (19% portion):

  • Years 1–5: 0% reduction
  • Years 6–21: 6% per year
  • Year 22: 4%
  • Full exemption after 22 years of ownership

For social charges (17.2% portion):

  • Years 1–5: 0% reduction
  • Years 6–21: 1.65% per year
  • Year 22: 1.60%
  • Years 23–30: 9% per year
  • Full exemption after 30 years of ownership

This means if you sell a property you've held for over 30 years, you pay zero capital gains tax and zero social charges.

The Principal Residence Exemption

One of the most valuable tax breaks in France: gains on the sale of your principal residence (résidence principale) are completely exempt from capital gains tax and social charges — with no cap on the amount.

To qualify, the property must be your actual, habitual, and primary residence at the time of sale. A second home, rental property, or holiday home does not qualify.

Example: If you bought an apartment in Paris for €400,000 and sell it five years later for €600,000 while living in it as your main home, the entire €200,000 gain is tax-free.

This is one reason many expats moving to France prioritise purchasing their primary residence early.

Practical Example: Selling a French Rental Property

Let's say you purchased a rental apartment in Lyon 10 years ago for €250,000 (including notarial fees) and sell it in 2025 for €400,000.

  1. Gross gain: €400,000 – €250,000 = €150,000
  2. Flat 15% works allowance (held > 5 years): €250,000 × 15% = €37,500
  3. Adjusted gain: €150,000 – €37,500 = €112,500
  4. Income tax taper (years 6–10 = 5 years × 6%): 30% reduction → €112,500 × 70% = €78,750 taxable for income tax
  5. Social charges taper (years 6–10 = 5 years × 1.65%): 8.25% reduction → €112,500 × 91.75% = €103,219 taxable for social charges
  6. Income tax: €78,750 × 19% = €14,962.50
  7. Social charges: €103,219 × 17.2% = €17,753.67
  8. Total CGT: approximately €32,716

Capital Gains Tax on Securities and Financial Assets

For expats with investment portfolios, shares, bonds, or other securities, the rules differ from real estate.

The Flat Tax (Prélèvement Forfaitaire Unique — PFU)

Since 2018, France has applied a flat tax of 30% on capital gains from securities, consisting of:

  • 12.8% income tax
  • 17.2% social charges

This flat tax (known as the PFU or "flat tax") applies to gains from the sale of shares, bonds, mutual funds, ETFs, and other movable assets.

Opting for the Progressive Scale

Alternatively, you can elect to be taxed under the progressive income tax scale instead of the flat tax. This is advantageous if your marginal tax rate is below 12.8%. Under the progressive option:

  • You may benefit from a partial exemption of 50% for shares held between 2 and 8 years, or 65% for shares held more than 8 years (applies only to shares acquired before 1 January 2018).
  • Social charges of 17.2% still apply, but a portion (6.8% CSG) becomes deductible from your taxable income the following year.

This election applies globally to all your investment income for the year — you cannot cherry-pick between the flat tax and progressive scale for different types of income.

Cryptocurrency and Digital Assets

France taxes capital gains on cryptocurrency disposals. For occasional sellers (non-professional traders), the flat tax rate of 30% applies to net annual gains exceeding €305. Professional crypto traders are taxed under the BIC (industrial and commercial profits) regime at progressive rates.

Social Charges: The Hidden Cost Expats Overlook

One of the most common mistakes expats make when estimating their French capital gains tax is forgetting about social charges (prélèvements sociaux). At 17.2%, these charges effectively add a second layer of tax on top of the headline income tax rate.

The 17.2% is composed of:

  • CSG (Contribution Sociale Généralisée): 9.2%
  • CRDS (Contribution pour le Remboursement de la Dette Sociale): 0.5%
  • Prélèvement de solidarité: 7.5%

EU/EEA Expats and Social Charges

A landmark European Court of Justice ruling (the de Ruyter case) established that EU/EEA residents who are affiliated with another EU/EEA country's social security system should not be subject to full French social charges on investment income. If you are covered by another EU country's social security, you may only owe the 7.5% solidarity levy instead of the full 17.2%.

This is particularly relevant for expats who have recently moved to France and may still be under their home country's social security system during a transitional period.

Double Taxation Treaties: Protecting Yourself from Being Taxed Twice

France has an extensive network of double taxation agreements (DTAs) with over 120 countries, including the UK, United States, Canada, Australia, Germany, and most EU nations. These treaties are essential for expats.

How Treaties Affect Capital Gains

Most French DTAs follow the OECD Model Tax Convention. Under these treaties:

  • Real estate gains are generally taxable in the country where the property is located (the "situs" country). So if you're a French resident selling a UK property, the UK has the primary right to tax the gain, but France can also tax it — while granting a tax credit for UK tax paid.
  • Securities and movable property gains are typically taxable only in the country of residence. So a French tax resident selling US stocks would generally pay tax in France, not the US (with some exceptions for substantial holdings in certain treaties).

The US-France Tax Treaty: Special Considerations

American expats face a unique situation because the US taxes its citizens on worldwide income regardless of residency. Under the US-France tax treaty:

  • France generally has the primary taxing right on capital gains if you are a French resident.
  • The US allows a Foreign Tax Credit (FTC) for French taxes paid, preventing double taxation.
  • The €305 crypto exemption and French holding period allowances on real estate do not exist in US tax law, creating potential mismatches that require careful planning.

The UK-France Tax Treaty

British expats moving to France should note:

  • UK principal private residence relief and French résidence principale exemption operate independently.
  • Gains on UK property may be taxed in both countries, with France providing a credit for UK CGT paid.
  • UK ISA gains, which are tax-free in the UK, are taxable in France once you become a French tax resident.

Common Mistakes Expats Make With French Capital Gains Tax

Avoiding these pitfalls can save you significant money and stress:

  1. Assuming your home country's rules apply. France has its own definitions of taxable gains, allowable deductions, and exemptions. Don't assume like-for-like equivalence.

  2. Ignoring social charges. The 17.2% social charges are not optional and apply on top of income tax. Many expats budget only for the 19% (property) or 12.8% (securities) rate and are shocked by the real total.

  3. Failing to declare worldwide gains. French tax residents must report capital gains from all countries. Non-disclosure can result in severe penalties — up to 80% of the unpaid tax for deliberate concealment.

  4. Not keeping records of acquisition costs. If you cannot prove your purchase price, the French tax authorities may use a deemed acquisition cost that could inflate your taxable gain.

  5. Missing the principal residence exemption. Some expats don't realise they need to be living in the property at the time of sale. Moving out and renting it for a period before selling may disqualify the exemption.

  6. Overlooking treaty benefits. Failing to claim tax credits under applicable double taxation treaties leads to unnecessary double taxation.

  7. Selling assets just before establishing French residency. Timing matters. Disposing of appreciated assets before becoming a French tax resident can legitimately reduce your French tax exposure — but this must be genuine and properly documented.

Key Deadlines and Filing Requirements for 2025/2026

French tax returns are filed annually, typically between April and June. For the 2025/2026 tax year:

  • Real estate capital gains: The notaire (notary) handling the property sale calculates and withholds the CGT at completion. You then report the gain on your annual return (Form 2042-C) for informational purposes. No additional payment is usually required.
  • Securities capital gains: Reported on your annual income tax return (Form 2042 and annexes). French financial institutions issue IFU (Imprimé Fiscal Unique) statements summarising your transactions.
  • Foreign gains: Reported on Form 2047 (income from abroad) and carried over to Form 2042-C. You claim treaty credits on Form 2042-C.
  • Cryptocurrency gains: Reported on Form 2086.

Online filing deadlines vary by department (geographic zone), typically falling between mid-May and early June. Late filing incurs a 10% penalty (rising to 40% after a formal notice).

Frequently Asked Questions

Do I pay French capital gains tax if I sell my home country property?

Yes, if you are a French tax resident, you must declare worldwide capital gains, including property sold abroad. However, a double taxation treaty will usually grant you a tax credit for taxes paid in the country where the property is located.

Is there a capital gains tax exemption for expats leaving France?

France has an exit tax (which was reformed in 2019) that may apply if you hold substantial securities portfolios (gains exceeding €800,000 or a 50%+ holding in a company). The tax is assessed but can be deferred if you move to an EU/EEA country, and is cancelled after a certain holding period.

Are there any special CGT exemptions for first-time sellers?

Yes. Non-residents (and former French residents) may benefit from a one-time exemption of up to €150,000 on the sale of a French property, provided certain conditions are met (e.g., the seller was previously a French tax resident and sells within 10 years of leaving France).

Can I offset capital losses against gains in France?

For securities, yes — capital losses can be carried forward for 10 years and offset against future capital gains of the same category. For real estate, losses generally cannot be offset against gains (each property transaction is treated independently).

Conclusion: Plan Before You Pack

Moving to France is an exciting life decision, but the tax implications — especially around capital gains — deserve careful advance planning. Here are the key takeaways:

  • French tax residents pay CGT on worldwide gains, not just French assets.
  • Real estate gains are taxed at a combined rate of up to 36.2% (plus possible surtax), but generous holding period allowances and the principal residence exemption can dramatically reduce or eliminate the tax.
  • Securities gains face a 30% flat tax, with an option to elect progressive rates if beneficial.
  • Social charges at 17.2% are a significant additional cost that many expats underestimate.
  • Double taxation treaties are your best protection against being taxed twice — but you must actively claim the benefits.
  • Timing asset disposals around your move to France can make a substantial financial difference.
