France vs Portugal: Comparing Capital Gains Tax in 2025/2026

If you're an investor, expat, or property owner weighing your options between France and Portugal, understanding the France vs Portugal capital gains tax landscape is essential. Both countries sit within the EU, share a bilateral tax treaty, and attract significant foreign investment — yet their approaches to taxing capital gains diverge in meaningful ways.

In this comprehensive capital gains tax comparison for the 2025/2026 tax year, we break down rates, exemptions, holding-period reductions, and real-world examples so you can make informed financial decisions. Whether you're selling property, disposing of shares, or planning a cross-border relocation, this tax comparison France Portugal guide has you covered.

Overview: How France and Portugal Tax Capital Gains

Before diving into the details, it helps to understand the fundamental philosophy each country takes toward capital gains.

France generally treats capital gains as a distinct category of income but applies social charges (contributions sociales) on top of the flat tax or progressive income tax. The system includes generous holding-period abatements for certain assets — particularly real estate.
Portugal taxes capital gains either at a flat rate or by including 50% of the gain in your taxable income (for residents), depending on the asset type. Portugal's former Non-Habitual Resident (NHR) regime — which offered favorable treatment for foreign-source capital gains — has been replaced by a new incentive scheme with different eligibility rules.

Both systems distinguish between real estate capital gains and financial/securities capital gains, and both offer specific rules for residents versus non-residents.

Real Estate Capital Gains: A Detailed Comparison

Property is one of the most common triggers for capital gains tax, especially for expats and cross-border investors. Let's examine how each country handles the sale of real property.

France: Real Estate Capital Gains Tax

When you sell property in France (other than your primary residence), the taxable gain is calculated as the sale price minus the acquisition price (adjusted for purchase costs, improvement works, and notarial fees). Key rules for 2025/2026:

Flat rate: 19% income tax on the net gain.
Social charges: 17.2% (CSG, CRDS, and solidarity levy). EU/EEA residents who are insured under another EU social security system may pay a reduced rate of 7.5%.
Holding-period abatement (income tax): 6% per year from the 6th to the 21st year, then 4% in the 22nd year. After 22 years of ownership, the gain is fully exempt from income tax.
Holding-period abatement (social charges): 1.65% per year from years 6–21, 1.60% in year 22, then 9% per year from years 23–30. After 30 years, the gain is fully exempt from social charges.
Surtax: An additional surtax of 2% to 6% applies when the net taxable gain exceeds €50,000.
Primary residence: Completely exempt — no conditions on reinvestment.

Practical example — France: Imagine you purchased a rental apartment in Lyon for €200,000 (including fees) and sell it 10 years later for €350,000. Your gross gain is €150,000.

After the flat-rate 7.5% uplift for acquisition costs and 15% for improvements (if no receipts): adjusted purchase price = €200,000 + €15,000 + €30,000 = €245,000. Net gain = €105,000.
Income tax abatement for 10 years of ownership (5 years × 6% = 30%): taxable gain for income tax = €105,000 × 70% = €73,500.
Income tax: €73,500 × 19% = €13,965.
Social charges abatement (5 years × 1.65% = 8.25%): taxable gain for social charges = €105,000 × 91.75% = €96,337.
Social charges: €96,337 × 17.2% = €16,570.
Surtax: The net gain exceeds €50,000, so a surtax of 2% applies to the portion over €50,000 = 2% × €23,500 = €470.
Total tax ≈ €31,005 (effective rate of about 29.5% on the gross gain of €105,000).

Portugal: Real Estate Capital Gains Tax

Portugal calculates the taxable gain as the sale price minus the acquisition price, with the acquisition price adjusted for inflation using official coefficients (coeficientes de desvalorização da moeda). Key rules for 2025/2026:

Residents: Only 50% of the net capital gain is added to your taxable income and taxed at progressive IRS rates (ranging from 14.5% to 48%, plus a solidarity surcharge of up to 5% for very high incomes).
Non-residents: The full gain is taxed at a flat rate of 28%. However, EU/EEA residents may elect to be taxed under the same conditions as Portuguese residents (50% inclusion at progressive rates), which can be beneficial for lower-income taxpayers.
Primary residence exemption: The gain on the sale of your primary residence is exempt if you reinvest the proceeds in another primary residence within the EU/EEA within 36 months (or 24 months before the sale). Partial reinvestment leads to partial exemption.
Improvement costs: Documented improvement expenditures from the last 12 years can be deducted.
No holding-period abatement beyond the inflation adjustment — Portugal does not offer a sliding-scale reduction based on years of ownership.

Practical example — Portugal: You purchased a rental apartment in Lisbon for €200,000 and sell it 10 years later for €350,000. Assume the inflation coefficient adjusts the acquisition price to €230,000 and you spent €10,000 on documented improvements.

Net gain: €350,000 − €230,000 − €10,000 = €110,000.
As a resident, 50% is taxable = €55,000.
If your other taxable income is €40,000, total taxable income = €95,000. The marginal rate at this level is 45% (plus possible solidarity surcharge).
Approximate additional tax on the €55,000 gain portion ≈ €22,000–€24,750 depending on exact bracket allocation.
Effective rate on the full €110,000 gain ≈ 20–22.5%.

Key Takeaway: Real Estate

For short-to-medium holding periods (under 15 years), Portugal's 50% inclusion rule often results in a lower effective tax rate than France's combined 36.2% (before abatements). However, France's generous holding-period abatements mean that for very long holding periods (22–30 years), France becomes significantly cheaper — and eventually tax-free.

Financial and Securities Capital Gains Compared

Both countries tax gains on shares, bonds, funds, and other financial instruments, but the mechanisms differ.

France: The Prélèvement Forfaitaire Unique (PFU)

France's default system for taxing investment income and capital gains on securities is the PFU (flat tax), set at 30% (12.8% income tax + 17.2% social charges). Key points:

Option for progressive scale: Taxpayers can elect to have all investment income taxed under the progressive income tax scale instead of the PFU. This benefits those in lower tax brackets.
Abatement for shares acquired before 2018: A holding-period abatement of 50% (2–8 years) or 65% (8+ years) may apply if you opt for the progressive scale and acquired shares before January 1, 2018.
Non-residents: Generally exempt from French tax on securities gains (provided they don't hold >25% of the company and benefit from a tax treaty). This makes France quite favorable for non-resident investors.
Crypto-assets: Gains exceeding €305 per year are taxed at the 30% PFU (or progressive scale by election).

Portugal: Flat Rate or 50% Inclusion

Portugal taxes securities capital gains as follows:

Residents: Gains on the sale of shares and other securities are taxed at a 28% flat rate. Alternatively, residents can opt to include the gains in their taxable income at progressive rates — but unlike real estate, there is no 50% inclusion benefit for securities.
Non-residents: Gains on Portuguese securities are taxed at 28%. However, gains on foreign securities are generally not taxable in Portugal for non-residents.
Crypto-assets: Gains on crypto held for less than 365 days are taxed at 28%. Gains on crypto held for more than 365 days are exempt — a notable advantage over France.
Shares held for 2+ years in SMEs: Certain qualifying holdings in small and medium enterprises may benefit from reduced taxation or exemption.

Key Takeaway: Securities

Scenario	France	Portugal	Advantage
Resident selling shares (short-term)	30% PFU	28% flat	Portugal (marginally)
Resident selling shares (pre-2018 acquisition, 8+ years, low income)	Potentially <20% via progressive scale + abatement	28% flat or progressive (no abatement)	France
Non-resident selling shares	Usually 0% (treaty protection)	28% on Portuguese securities	France
Crypto held >365 days	30% PFU	Exempt	Portugal (significantly)

The France-Portugal Double Taxation Treaty

France and Portugal have a bilateral double taxation agreement (DTA) in force, which is critical for anyone with financial interests in both countries.

Key Provisions Relevant to Capital Gains

Real estate gains: Taxed in the country where the property is situated. If you are a French resident selling Portuguese property, Portugal taxes the gain first, and France provides a tax credit to avoid double taxation (and vice versa).
Shares deriving value from real estate: May be taxed in the country where the underlying real estate is located.
Other securities: Generally taxed only in the country of residence of the seller.
Elimination of double taxation: France uses the tax credit method — meaning French residents can credit Portuguese tax paid against their French liability on the same income.

Practical Implication

If you're a French tax resident selling a property in Lisbon, you'll pay Portuguese capital gains tax first, then declare the gain in France. France will give you a credit equal to the French tax attributable to that gain, effectively ensuring you pay the higher of the two countries' rates — not both combined.

This makes the DTA a crucial planning tool. Understanding which country has primary taxing rights can save you thousands of euros.

Special Regimes and Incentives

Portugal: The New Tax Incentive for Scientific Research and Innovation (IFICI)

Portugal's famous Non-Habitual Resident (NHR) regime closed to new applicants in 2024. It has been replaced by the IFICI regime (Incentivo Fiscal à Investigação Científica e Inovação), effective from 2024 onward. Key differences:

Eligibility is narrower — focused on professionals in scientific research, innovation, qualified professions, and certain startup activities.
Qualifying individuals enjoy a 20% flat rate on Portuguese-source employment and self-employment income for 10 years.
Foreign-source capital gains may be exempt from Portuguese tax for qualifying IFICI beneficiaries, similar to the old NHR benefit. However, the precise scope depends on the applicable double taxation treaty.
Not all expats will qualify — the regime is no longer a blanket incentive for retirees or general high-net-worth individuals.

France: No Equivalent Flat-Rate Expat Regime for Capital Gains

France does not offer a comparable flat-rate regime for new residents. However, France does provide:

Inbound impatriate regime (Article 155 B): Offers partial income tax exemptions on certain compensation elements for employees and directors transferred to France, but this does not directly reduce capital gains tax.
Exit tax (Article 167 bis): French residents who have been tax resident for at least 6 of the last 10 years and hold securities worth over €800,000 (or representing >50% of a company) may face an exit tax on unrealized gains when they move abroad. The tax can be deferred and eventually cancelled under certain conditions.

Common Mistakes to Avoid

Assuming NHR still applies: Many online resources still reference Portugal's NHR regime. New applicants from 2024 onward must qualify under IFICI or use the standard tax rules.
Ignoring social charges in France: The 17.2% social charges often surprise taxpayers who focus only on the 19% income tax rate.
Forgetting inflation adjustment in Portugal: The acquisition cost is indexed to inflation, which can meaningfully reduce the taxable gain.
Not claiming the DTA credit: If you pay tax in both countries on the same gain, ensure you claim the foreign tax credit to avoid double taxation.
Overlooking the French exit tax: If you're moving from France to Portugal (or vice versa), the exit tax on unrealized securities gains can be substantial.

FAQ: France vs Portugal Capital Gains Tax

Which country has a lower capital gains tax rate on property? It depends on the holding period and your overall income. For properties held fewer than 15 years, Portugal's 50% inclusion rule often yields a lower effective rate for residents. For properties held over 22–30 years, France's abatements reduce the tax to zero.

Do I pay capital gains tax in both countries if I sell property abroad? No — the France-Portugal tax treaty prevents full double taxation. The country where the property is located taxes the gain first, and your country of residence provides a credit.

Is cryptocurrency taxed differently? Yes. Portugal exempts crypto gains on assets held for more than 365 days, while France taxes all crypto gains above €305 at 30%. This is a significant advantage for long-term crypto investors in Portugal.

Can I still benefit from Portugal's NHR regime? Only if you registered before the end of 2023/early 2024 transition period. New applicants must apply under the IFICI regime, which has stricter eligibility criteria.

What about capital gains on my primary residence? Both countries exempt gains on your primary residence. In France, the exemption is unconditional. In Portugal, you must reinvest the proceeds in another primary residence within the EU/EEA within 36 months.

Conclusion: Which Country Is Better for Capital Gains Tax?

There is no one-size-fits-all answer to the France vs Portugal capital gains tax question. Here are the key takeaways for 2025/2026:

For long-term real estate investors: France's holding-period abatements are extremely generous — full exemption after 22 years for income tax and 30 years for social charges. Portugal offers no equivalent time-based relief.
For short-to-medium-term property sales: Portugal's 50% inclusion rule typically produces a lower effective tax rate than France's combined 36.2% flat rate.
For securities investors resident in each country: Rates are broadly similar (30% in France vs 28% in Portugal), but France offers abatements on pre-2018 shares and exempts non-resident sellers.
For crypto investors: Portugal is the clear winner, with a full exemption on gains from crypto held over one year.
For non-residents selling securities: France is generally more favorable (often 0% under treaty protection), while Portugal charges 28%.
For cross-border situations: The France-Portugal DTA is essential. Always claim your foreign tax credit and consider the French exit tax if relocating.
