If you're an investor, expat, or digital nomad weighing up life in Southern Europe, understanding the Portugal Italy capital gains tax comparison is essential before you make your move. Both countries attract foreign residents with sunshine, culture, and — in some cases — competitive tax regimes. But when it comes to capital gains tax (CGT), the details matter enormously.
In this comprehensive guide for the 2025/2026 tax year, we'll compare capital gains tax in Portugal and Italy side by side, covering rates, exemptions, special regimes, and practical examples. By the end, you'll know which country has lower capital gains tax for your specific situation — and how to plan accordingly.
What Is Capital Gains Tax and Why Does It Matter?
Capital gains tax is the levy imposed on the profit you make when you sell an asset — such as shares, bonds, real estate, or cryptocurrency — for more than you originally paid. In both Portugal and Italy, CGT can significantly eat into your investment returns if you don't plan ahead.
For anyone considering relocating between these two countries, or investing across borders, the capital gains tax rate is often a decisive factor. Even a few percentage points can translate into thousands of euros saved or lost on a single transaction.
Portugal Capital Gains Tax: Rates and Rules for 2025/2026
Portugal's capital gains tax framework distinguishes clearly between real estate gains and financial asset gains, and between tax residents and non-residents.
Capital Gains on Real Estate (Imóveis)
For Portuguese tax residents, only 50% of the net capital gain from selling real estate is added to your taxable income. This amount is then taxed at Portugal's progressive income tax rates, which range from 14.5% to 48% (plus a solidarity surcharge of up to 5% on very high incomes). In effect, the maximum real tax rate on property gains can reach roughly 24% to 26.5% for the highest earners, though most taxpayers will pay considerably less.
Key exemptions include:
- Primary residence reinvestment relief: If you sell your main home and reinvest the proceeds in another primary residence within the EU/EEA within 36 months (or 24 months before the sale), the gain can be fully or partially exempt.
- Properties acquired before 1989: Gains on properties purchased before January 1, 1989, are generally exempt from CGT.
- Over-65 or retired exemption: Residents aged 65+ (or retired) can be exempt if they reinvest the gain in a qualifying life insurance contract or pension fund within six months.
For non-residents, the full capital gain on Portuguese real estate is taxed at a flat rate of 28% — unless the seller is an EU/EEA resident and elects to be taxed under the progressive rates (with only 50% of the gain included), which can sometimes result in a lower effective rate.
Capital Gains on Financial Assets (Shares, Bonds, Crypto)
Portuguese tax residents pay a flat rate of 28% on gains from selling shares, bonds, investment fund units, and other financial assets. Alternatively, they can opt to include these gains in their general taxable income and be taxed at progressive rates — a strategy that benefits those with low total income.
Cryptocurrency gains are now taxable in Portugal. Short-term crypto gains (assets held less than 365 days) are taxed at the 28% flat rate. Gains on crypto held for more than one year are exempt from capital gains tax.
Non-residents are generally not taxed on gains from the sale of Portuguese financial assets, unless the assets are shares in a company whose value derives more than 50% from Portuguese real estate.

Italy Capital Gains Tax: Rates and Rules for 2025/2026
Italy applies a somewhat different approach, with a notable emphasis on a flat substitute tax for financial assets and a more complex system for real estate.
Capital Gains on Real Estate (Immobili)
In Italy, capital gains from selling real estate are taxable as ordinary income if the property was held for less than five years (unless it was used as a primary residence for the majority of the ownership period). If you hold the property for five years or more, the gain is generally exempt from capital gains tax — a significant advantage over Portugal.
For gains that are taxable (i.e., short-term holdings), the seller can choose between:
- Including the gain in ordinary taxable income, taxed at Italy's progressive IRPEF rates ranging from 23% to 43% (plus regional and municipal surcharges of roughly 1.5–3.5%).
- Opting for a flat substitute tax of 26%, applied directly at the time of the notarial deed.
Key points:
- Primary residence exemption: If the property was your primary residence (prima casa) for the majority of the time you owned it, the gain is exempt regardless of holding period.
- Inherited property: Gains from selling inherited property are generally exempt from CGT.
- No partial inclusion: Unlike Portugal, Italy does not halve the gain before taxation — the full amount is taxed (though the five-year rule provides a powerful exemption).
Capital Gains on Financial Assets (Shares, Bonds, Crypto)
Italy levies a flat substitute tax of 26% on capital gains from shares, bonds, ETFs, and most other financial instruments. This is known as the imposta sostitutiva.
Notable exceptions:
- Italian government bonds (BTPs) and bonds from EU/EEA white-listed countries: gains are taxed at a reduced rate of 12.5%.
- Qualified participations (significant shareholdings in companies): these are now also subject to the 26% flat tax, having been aligned with the general regime in recent years.
Cryptocurrency gains in Italy are taxed at 26% as of 2025. Italy had considered raising the crypto CGT rate to 42%, but this increase has been deferred as of the latest legislative updates. There is an annual exemption threshold of EUR 2,000 — if your total crypto gains in a tax year are below this amount, no tax is due.
Non-residents are generally not taxed on gains from selling Italian financial assets (with exceptions for substantial participations and certain real-estate-rich companies), broadly similar to Portugal's approach.

Head-to-Head Comparison: Portugal vs Italy Capital Gains Tax
Let's put the two countries side by side for a clear picture:
| Category | Portugal (2025/2026) | Italy (2025/2026) |
|---|---|---|
| Real estate CGT — residents (short-term) | 50% of gain taxed at 14.5%–48% (effective max ~26.5%) | Full gain at 23%–43% IRPEF, or 26% flat substitute tax |
| Real estate CGT — residents (long-term) | Same as above (no holding-period exemption, but primary-residence reinvestment relief exists) | Exempt after 5 years (major advantage) |
| Real estate CGT — non-residents | 28% flat rate (or opt for progressive rates if EU/EEA) | 26% flat substitute tax (or IRPEF rates) |
| Financial assets CGT — residents | 28% flat rate | 26% flat rate (12.5% for government bonds) |
| Crypto CGT — residents | 28% (exempt if held >1 year) | 26% (EUR 2,000 annual exemption) |
| Financial assets CGT — non-residents | Generally exempt | Generally exempt |
| Primary residence exemption | Reinvestment relief (must buy new home) | Exempt if used as primary home for majority of ownership |
Which Country Has Lower Capital Gains Tax?
The answer depends on the type of asset and how long you hold it:
- For long-term real estate investors: Italy wins decisively. The five-year exemption means you pay zero CGT on property held more than five years. Portugal has no comparable holding-period exemption.
- For financial assets (shares, bonds, ETFs): Italy has a slight edge at 26% vs. Portugal's 28%. The difference is small but meaningful on large portfolios.
- For government bond investors: Italy is far more favorable at 12.5% vs. 28% in Portugal.
- For cryptocurrency investors: Portugal is better for long-term holders (exempt after one year), while Italy offers a small EUR 2,000 exemption but otherwise taxes at 26%.
- For short-term real estate flips: Both countries tax heavily; Portugal's effective rate may be lower for moderate earners thanks to the 50% inclusion rule, while Italy's 26% flat option provides certainty.
Practical Examples: Crunching the Numbers
Example 1: Selling an Investment Property After 7 Years
You purchased a rental apartment for EUR 200,000 and sell it for EUR 300,000, realizing a EUR 100,000 gain.
- In Portugal (tax resident, not primary home): 50% of the gain (EUR 50,000) is added to your taxable income. If your marginal rate is 37%, you'd owe approximately EUR 18,500 in CGT.
- In Italy (tax resident, held >5 years): EUR 0 in CGT. The gain is fully exempt.
Winner: Italy, by a wide margin.
Example 2: Selling a Stock Portfolio — EUR 50,000 Gain
- In Portugal: 28% × EUR 50,000 = EUR 14,000 in CGT.
- In Italy: 26% × EUR 50,000 = EUR 13,000 in CGT.
Winner: Italy, saving you EUR 1,000.

Example 3: Selling Cryptocurrency Held for 18 Months — EUR 30,000 Gain
- In Portugal: EUR 0 in CGT — the one-year holding exemption applies.
- In Italy: 26% × EUR 30,000 = EUR 7,800 in CGT (gain exceeds EUR 2,000 threshold).
Winner: Portugal, saving you EUR 7,800.
Special Tax Regimes: NHR 2.0 (Portugal) vs Flat Tax Regime (Italy)
Both countries offer special tax regimes that can dramatically alter the capital gains picture for new residents.
Portugal's NHR 2.0 / Tax Incentive for Scientific Research and Innovation
Portugal's original Non-Habitual Resident (NHR) program — which offered a flat 20% rate on qualifying Portuguese-source employment income and broad exemptions on foreign-source income — was phased out for new applicants from 2024. It has been replaced by a more targeted regime (sometimes called "NHR 2.0" or the Incentivo Fiscal à Investigação Científica e Inovação) aimed at professionals in specific scientific and tech fields.
For most investors and retirees, the new regime is less generous than the old NHR. Foreign-source capital gains may still benefit from treaty exemptions, but the blanket exemptions of the original NHR no longer apply to new entrants.
Italy's Flat Tax Regime for New Residents (Regime Forfettario per Neo-Residenti)
Italy offers a flat tax of EUR 100,000 per year on all foreign-source income (including capital gains) for qualifying new tax residents who have not been Italian tax residents for at least nine of the previous ten years. Family members can join for an additional EUR 25,000 each.
This means that for ultra-high-net-worth individuals with large foreign investment portfolios, Italy's flat tax regime can result in an effective capital gains tax rate near zero on foreign-source gains — regardless of the amount. It's one of the most attractive regimes in Europe for wealthy investors.
Key takeaway: If you have substantial foreign-source capital gains, Italy's flat tax regime is significantly more favorable than Portugal's current options.
Double Taxation Treaties and Cross-Border Considerations
Both Portugal and Italy have extensive networks of double taxation treaties (DTTs). If you're a resident of one country selling assets in the other — or in a third country — the applicable treaty can determine which country has taxing rights and provide relief from double taxation.
- Portugal has over 80 DTTs in force.
- Italy has over 100 DTTs in force.
In most treaties, capital gains on shares are taxable only in the country of residence, while capital gains on real estate are taxable in the country where the property is located (with a credit or exemption in the residence country).
Common mistakes to avoid:
- Assuming you're only taxed in one country: Even with a treaty, you may need to file in both countries and claim treaty relief.
- Ignoring exit taxes: Moving between countries can trigger deemed disposal rules or exit taxes on unrealized gains, particularly for substantial shareholdings.
- Forgetting about social surcharges: In Portugal, high earners may face the solidarity surcharge, and in Italy, regional/municipal surcharges add to the headline rate.

Frequently Asked Questions
Is capital gains tax lower in Portugal or Italy?
For most asset classes, Italy has a slightly lower headline CGT rate (26% vs. 28% on financial assets). For real estate held over five years, Italy offers a full exemption, making it substantially cheaper. However, Portugal is more favorable for long-term cryptocurrency holders (exempt after one year).
Do non-residents pay capital gains tax in Portugal and Italy?
Both countries tax non-residents on gains from real estate located within their borders. Gains from financial assets are generally exempt for non-residents in both countries, with certain exceptions for significant shareholdings.
Can I avoid capital gains tax by reinvesting in Portugal?
Yes — if you sell your primary residence and reinvest the proceeds in a new primary residence within the EU/EEA within the specified timeframe, you can qualify for full or partial exemption in Portugal. Italy offers a different but equally powerful exemption through the primary-residence and five-year holding rules.
How are crypto gains taxed in Portugal and Italy in 2025?
In Portugal, crypto gains are taxed at 28% unless the assets were held for more than one year (then exempt). In Italy, crypto gains are taxed at 26%, with an annual exemption of EUR 2,000.
What about Italy's proposed 42% crypto tax?
As of the 2025/2026 tax year, the proposed increase to 42% on crypto gains has not been enacted and the rate remains at 26%. Tax laws can change, so it's important to monitor legislative developments.
Key Takeaways: Portugal vs Italy Capital Gains Tax
- Italy generally offers lower capital gains tax rates on financial assets (26% vs. 28%) and a powerful five-year exemption on real estate.
- Portugal is more attractive for long-term crypto investors, with full exemption after a one-year holding period.
- Italy's flat tax regime for new residents (EUR 100,000/year on all foreign income) can be a game-changer for high-net-worth individuals — far outpacing Portugal's current offerings.
- Both countries exempt non-residents from CGT on most financial assets, but tax real estate gains.
- Double taxation treaties play a critical role for cross-border investors. Always verify treaty provisions before assuming a specific tax treatment.
