If you're an investor, expat, or digital nomad weighing life on the Iberian Peninsula, the Spain Portugal capital gains tax comparison is one of the most consequential financial decisions you'll face. Both countries attract foreign talent and capital, yet their tax regimes diverge in meaningful ways — ways that can cost or save you thousands of euros every year.
In this comprehensive guide for the 2025/2026 tax year, we'll dissect the capital gains tax (CGT) systems of Spain and Portugal side by side, so you can answer the critical question: which country has lower capital gains tax for your particular situation?
What Is Capital Gains Tax and Why Does It Matter for Spain and Portugal?
Capital gains tax is levied on the profit you make when you sell or dispose of an asset — shares, real estate, cryptocurrency, or other investments — for more than you paid for it. In both Spain and Portugal, the tax treatment depends on:
- Tax residency status (resident vs. non-resident)
- Type of asset (property, equities, crypto, etc.)
- Holding period in some cases
- Available exemptions and reliefs
Understanding these variables is essential. A blanket statement like "Portugal is cheaper" or "Spain is cheaper" ignores nuances that could flip the answer depending on your profile.
Spain Capital Gains Tax Rates: 2025/2026 Overview
Spain taxes capital gains as part of what it calls the renta del ahorro (savings income). Gains are separated from general income and taxed at progressive rates.
Resident Capital Gains Tax Rates
For Spanish tax residents in 2025/2026, the savings-income bands are:
| Taxable Gain (EUR) | Marginal Rate |
|---|---|
| Up to €6,000 | 19% |
| €6,001 – €50,000 | 21% |
| €50,001 – €200,000 | 23% |
| €200,001 – €300,000 | 27% |
| Over €300,000 | 28% |
These rates apply to net capital gains after allowable costs (purchase price, notary fees, transfer taxes, improvements for property, etc.) are deducted.
Example: If you sell Spanish shares and realise a gain of €80,000:
- First €6,000 at 19% = €1,140
- Next €44,000 at 21% = €9,240
- Remaining €30,000 at 23% = €6,900
- Total CGT ≈ €17,280 (effective rate ≈ 21.6%)

Non-Resident Capital Gains Tax
Non-residents selling Spanish assets are typically subject to a flat 19% rate if they are EU/EEA residents, or 24% for non-EU/EEA residents, unless a double taxation agreement (DTA) provides a lower rate. Buyers of Spanish property from non-residents must withhold 3% of the sale price as an advance payment toward the seller's CGT liability.
Key Spanish Exemptions and Reliefs
- Primary-residence reinvestment relief: If you sell your main home and reinvest the full proceeds in a new primary residence within two years, the gain can be fully exempt.
- Over-65 exemption: Residents aged 65+ who sell their principal home are completely exempt from CGT on that sale, with no reinvestment requirement.
- Loss offsetting: Capital losses can offset capital gains in the same year, and unused losses can be carried forward for four years.
- Beckham Law (Régimen de Impatriados): Qualifying inbound workers can elect to be taxed as non-residents for up to six years, potentially accessing the flat 24% rate on employment income — but note that capital gains from Spanish-source assets may still be taxed under savings-income rules, and foreign-source capital gains could be exempt (complex rules apply).
Portugal Capital Gains Tax Rates: 2025/2026 Overview
Portugal's CGT framework differs depending on whether the gain is from movable assets (shares, funds, crypto) or immovable property (real estate), and whether the taxpayer is a resident or non-resident.
Resident Capital Gains Tax on Financial Assets
For Portuguese tax residents, gains on shares, bonds, funds, derivatives, and cryptocurrency are taxed at a flat autonomous rate of 28%. However, taxpayers can opt to include (englobamento) these gains in their general income if their marginal IRS rate is lower than 28%.
The 2025/2026 IRS progressive rates range from 13% to 48%, so englobamento only benefits those with relatively low total income.
Resident Capital Gains Tax on Property
When a Portuguese resident sells real estate, only 50% of the net gain is subject to tax. That 50% is added to general income and taxed at progressive IRS rates.
Example: You sell a Portuguese property for €400,000, having purchased it for €250,000 with €10,000 in allowable costs. Net gain = €140,000. Taxable amount = €70,000. If your other income places you in the 37% bracket, the CGT on the property is roughly €70,000 × 37% = €25,900 — an effective rate on the full gain of about 18.5%.

Non-Resident Capital Gains Tax
- Property: Non-residents face a flat 28% on the full gain — unless they are EU/EEA residents, in which case they can elect the 50%-inclusion method available to residents, potentially resulting in a lower effective rate.
- Shares in Portuguese companies: Generally taxed at 28% for non-residents, although many DTAs reduce or eliminate this.
- Crypto and other financial instruments: 28% flat rate for non-residents, subject to treaty provisions.
Key Portuguese Exemptions and Reliefs
- Primary-residence reinvestment relief: Similar to Spain, residents who reinvest the proceeds from selling their main home into a new primary residence within the EU/EEA (within 36 months after or 24 months before the sale) may be fully or partially exempt.
- Inflation adjustment coefficients: For property held for more than two years, the acquisition cost is adjusted upward by official inflation coefficients, reducing the taxable gain.
- Holding-period considerations for shares: Gains on shares in micro and small companies held for more than one year may benefit from partial exclusion. Long-term holders of qualifying Portuguese venture capital or SME shares can access reduced taxation.
- Non-Habitual Resident (NHR) regime — sunset and successor: The original NHR regime closed to new applicants after 2023. Its 2024/2025 successor — the Incentivo Fiscal à Investigação Científica e Inovação (IFICI/NHR 2.0) — targets a narrower group (researchers, tech professionals, start-up employees). Under NHR 2.0, qualifying foreign-source capital gains may be exempt in Portugal for 10 years, depending on the income category and source-country taxation. This can be a powerful benefit, but eligibility is restricted compared to the original NHR.
Head-to-Head: Spain vs Portugal Capital Gains Tax Compared
Let's put the two systems side by side for the 2025/2026 tax year.
| Factor | Spain | Portugal |
|---|---|---|
| Resident rate — shares/financial assets | 19%–28% (progressive) | 28% flat (or opt for progressive 13%–48%) |
| Resident rate — property | 19%–28% on full gain (progressive) | Progressive rate on 50% of gain |
| Non-resident rate (EU/EEA) | 19% flat | 28% (or 50%-inclusion election for property) |
| Non-resident rate (non-EU) | 24% flat | 28% flat |
| Primary-residence relief | Full exemption on reinvestment (or age 65+) | Full/partial exemption on reinvestment |
| Loss carry-forward | 4 years | 5 years (for financial assets taxed via englobamento); property losses can offset property gains in the same year |
| Inflation indexation on property | No | Yes (coefficients applied to acquisition cost) |
| Crypto taxation | 19%–28% as savings income | 28% flat (gains from crypto held <365 days; long-term holdings exempt for residents) |
| Special expat regime | Beckham Law (employment-focused) | NHR 2.0/IFICI (research & innovation-focused) |
Which Country Has Lower Capital Gains Tax on Shares?
For small to moderate gains (under roughly €50,000), Spain's 19%–21% rates beat Portugal's flat 28%. For very large gains (above €300,000), Spain's top rate of 28% converges with Portugal's 28%, making the two broadly equivalent — unless the Portuguese taxpayer has low overall income and opts for englobamento, which could bring the rate below 28%.
Verdict for shares: Spain is generally more favourable unless your total income is low enough for englobamento in Portugal.
Which Country Has Lower Capital Gains Tax on Property?
Portugal's 50%-inclusion rule is a game-changer. Because only half the gain is taxed, the effective rate on property gains often lands between 13% and 24% for residents — comfortably below Spain's 19%–28% progressive scale applied to the full gain.
Verdict for property: Portugal typically offers a lower effective rate for residents selling real estate, especially for medium-to-large gains.
Which Country Is Better for Crypto Investors?
Portugal exempts crypto gains for residents who have held the asset for more than 365 days — a powerful incentive for long-term holders. Spain offers no such exemption and taxes crypto gains at the standard 19%–28% savings-income rates regardless of holding period.
Verdict for crypto: Portugal is significantly more favourable for long-term crypto investors.
Practical Scenarios: Real-World Tax Comparisons
Scenario 1: Selling a €500,000 Share Portfolio (Gain: €150,000)
Spain (resident):
- €6,000 × 19% + €44,000 × 21% + €100,000 × 23% = €1,140 + €9,240 + €23,000 = €33,380
- Effective rate: 22.3%
Portugal (resident, flat rate):
- €150,000 × 28% = €42,000
- Effective rate: 28%
Portugal (resident, englobamento with €30,000 other income):
- Total income €180,000 → marginal rate around 45–48%, so englobamento is not beneficial.
Winner: Spain by roughly €8,600.

Scenario 2: Selling a Property (Gain: €200,000)
Spain (resident, no reinvestment):
- €6,000 × 19% + €44,000 × 21% + €150,000 × 23% = €1,140 + €9,240 + €34,500 = €44,880
- Effective rate: 22.4%
Portugal (resident, no reinvestment, other income €40,000):
- Taxable gain: 50% × €200,000 = €100,000
- Added to €40,000 = €140,000 total income
- Marginal rate ≈ 43.5%, but blended rate on the €100,000 slice is roughly 38%–40%
- CGT ≈ €100,000 × 39% = **€39,000**
- Effective rate on full gain: ~19.5% (after inflation coefficients, the effective rate could drop further)
Winner: Portugal, potentially saving around €5,000–€8,000 depending on inflation adjustment.
Scenario 3: Long-Term Bitcoin Holder (Gain: €100,000, Held 2+ Years)
Spain: taxed at 19%–23% → approximately €21,380.
Portugal: held over 365 days → €0 (exempt for residents).
Winner: Portugal — by €21,380.
Double Taxation Agreements and Cross-Border Considerations
Spain and Portugal have an extensive network of double taxation agreements (DTAs) with countries worldwide, as well as a bilateral DTA between themselves. Key points:
- Real estate gains are generally taxable in the country where the property is located, regardless of the seller's residence. The residence country then provides a credit or exemption under the DTA.
- Share gains are typically taxable only in the country of residence, unless the shares derive more than 50% of their value from immovable property in the source country.
- EU residents selling property in either Spain or Portugal can often elect to be taxed under the same rules as local residents, thanks to EU non-discrimination principles.

Common Mistakes and Misconceptions
Avoid these pitfalls when comparing Spain and Portugal capital gains tax:
- Assuming Portugal is always cheaper. For financial-asset gains under €50,000, Spain's starting rate of 19% is substantially lower than Portugal's flat 28%.
- Ignoring regional taxes in Spain. Some autonomous communities (e.g., the Basque Country, Navarra) have their own savings-income schedules that may differ from the state rates.
- Forgetting the 3% withholding in Spain. Non-residents selling Spanish property face an automatic 3% retention by the buyer, which must be reconciled with the actual CGT due.
- Overlooking Portugal's inflation coefficients. These reduce the taxable gain on property and are updated annually — failing to apply them means overstating your liability.
- Conflating NHR with NHR 2.0. The original NHR regime was far more generous. The new IFICI scheme has strict eligibility criteria and different rules. Don't rely on outdated information.
- Not considering exit taxes. If you relocate from one country to the other, Spain may impose an "exit tax" on unrealised gains in shares worth over €4 million, and Portugal has similar anti-avoidance provisions.
Frequently Asked Questions
Do I pay capital gains tax in both Spain and Portugal if I own assets in both countries?
Possibly, but the Spain–Portugal DTA prevents double taxation. Typically, you pay tax in the source country and receive a credit in your country of residence.
Can I avoid capital gains tax by moving from Spain to Portugal (or vice versa)?
Changing residence can alter your tax obligations, but both countries have anti-avoidance rules, including exit taxes and minimum residency requirements. A move must be genuine, not solely tax-motivated, to withstand scrutiny.
Is cryptocurrency taxed differently from shares?
Yes. In Portugal, crypto held over 365 days by residents is exempt — a benefit not available in Spain. In Spain, crypto is taxed identically to other savings income.
What if I'm a non-EU citizen living in neither country?
You'll be taxed as a non-resident. Spain applies 24% (non-EU) or 19% (EU/EEA), while Portugal applies 28%. DTAs with your home country may reduce these rates.
Which country is better for retirees selling investments?
It depends on the asset type and gain size. Spain's over-65 primary-residence exemption is exceptionally generous. For share portfolios, Spain's lower starting rates often win. For property, Portugal's 50%-inclusion rule usually wins.
Conclusion: Spain vs Portugal — Which Country Has Lower Capital Gains Tax?
There is no universal winner in the Spain Portugal capital gains tax comparison. The optimal choice hinges on:
- Asset type: Portugal favours property sellers (50% inclusion) and long-term crypto holders (exemption). Spain favours shareholders with gains under ~€200,000.
- Gain size: Spain's progressive rates start lower (19%) but climb to 28%. Portugal's flat 28% on financial assets can be higher for small gains but equivalent for large ones.
- Residency status: Non-EU non-residents face 24% in Spain vs. 28% in Portugal — advantage Spain.
- Special regimes: Spain's Beckham Law and Portugal's NHR 2.0 serve different profiles; neither is broadly available.
- Holding period: Portugal's 365-day crypto exemption has no Spanish equivalent.
