If you're weighing up life on the Iberian Peninsula, the Spain Portugal wealth tax comparison should be high on your research list. Both countries attract retirees, digital nomads, and high-net-worth individuals (HNWIs) with their sunshine and lifestyle — but their approaches to taxing personal wealth diverge sharply. Understanding which country has lower wealth tax could save you tens of thousands of euros every year.

In this in-depth guide for the 2025/2026 tax year, we compare Spain's long-standing Impuesto sobre el Patrimonio (and its newer Solidarity Tax) with Portugal's more indirect approach to wealth taxation. We'll cover rates, thresholds, exemptions, practical examples, and common mistakes so you can make an informed decision about where to base your financial life.

How Wealth Tax Works: A Quick Primer

Before diving into the country-by-country breakdown, let's clarify what a "wealth tax" actually is.

A wealth tax is an annual levy on a taxpayer's net assets — the total value of what you own (real estate, investments, bank deposits, luxury goods) minus what you owe (mortgages, debts). Unlike income tax, which taxes money as you earn it, wealth tax targets the stock of accumulated assets, regardless of whether they produce income.

Key points to remember:

  • Residents are typically taxed on their worldwide net assets.
  • Non-residents are usually taxed only on assets located within the country.
  • Thresholds, rates, and exemptions vary dramatically between jurisdictions — and even between regions within the same country.

Spain's Wealth Tax Regime in 2025/2026

Spain has one of Europe's most established wealth tax systems, and in recent years it has actually expanded its reach. There are now two layers to be aware of.

The Traditional Wealth Tax (Impuesto sobre el Patrimonio)

Spain's regular wealth tax applies to both residents and non-residents. Here are the key parameters for 2025/2026:

  • General tax-free allowance: €700,000 per taxpayer (this is the state-level default; some autonomous communities set different thresholds).
  • Primary residence exemption: Up to €300,000 of the value of your main home is exempt.
  • Effective taxable threshold for residents: If you own a primary residence, you may effectively shelter up to €1,000,000 before wealth tax kicks in (€700,000 allowance + €300,000 home exemption).
  • Non-residents: Entitled to the €700,000 allowance but not the primary-residence exemption (since their main home is abroad).

State-level progressive rates:

Taxable Net Wealth (€) Marginal Rate
Up to 167,129 0.2%
167,129 – 334,253 0.3%
334,253 – 668,500 0.5%
668,500 – 1,337,000 0.9%
1,337,000 – 2,673,999 1.3%
2,673,999 – 5,347,998 1.7%
5,347,998 – 10,695,996 2.1%
Over 10,695,996 3.5%

Regional variation alert: Spain's autonomous communities can modify rates, allowances, and even effectively eliminate the tax. Madrid, for instance, has historically applied a 100% rebate — meaning residents of Madrid paid zero wealth tax. However, this advantage has been partially offset by the national Solidarity Tax (see below). Catalonia and Valencia, by contrast, broadly follow or exceed state rates.

The Solidarity Tax on Large Fortunes (Impuesto Temporal de Solidaridad de las Grandes Fortunas)

Introduced in late 2022 and extended through 2025, the Solidarity Tax was designed to ensure that wealthy taxpayers in low-tax regions (like Madrid) still contribute. Key features:

  • Threshold: Applies to net assets above €3,000,000 (after the €700,000 general allowance).
  • Rates:
    • €3,000,000 – €5,347,998: 1.7%
    • €5,347,998 – €10,695,996: 2.1%
    • Over €10,695,996: 3.5%
  • Credit mechanism: Any regular wealth tax already paid is credited against the Solidarity Tax, so you don't pay double. In practice, only taxpayers in regions with low or zero regular wealth tax (Madrid, Andalusia) face an additional bill.
  • Applies to both residents and non-residents with Spanish-situs assets above the threshold.

Practical Example: Spain

Scenario: Maria is a tax resident of Madrid with total worldwide net assets of €4,000,000, including a primary residence valued at €600,000 and a mortgage of €100,000.

  1. Net assets: €4,000,000
  2. Primary-residence exemption: €300,000 (capped, even though her home equity is €500,000)
  3. General allowance: €700,000
  4. Taxable base: €4,000,000 − €300,000 − €700,000 = €3,000,000
  5. Regular Madrid wealth tax: €0 (Madrid's 100% rebate)
  6. Solidarity Tax check: Net wealth after €700,000 allowance = €3,300,000; amount above €3,000,000 threshold = €300,000 taxed at 1.7% = €5,100

Maria owes €5,100 in Solidarity Tax despite living in "tax-free" Madrid.

Had Maria lived in Catalonia, her regular wealth tax on a €3,000,000 taxable base would be approximately €25,000–€28,000 (Catalonia's rates are at or above state level), and the Solidarity Tax would then be credited to zero because her regular wealth tax already exceeds it.

Portugal's Approach to Wealth Tax in 2025/2026

Portugal does not levy a traditional, broad-based net wealth tax. There is no Portuguese equivalent of Spain's Impuesto sobre el Patrimonio that captures bank accounts, shares, art, and other movable assets.

However, Portugal is not entirely wealth-tax-free. It uses a property-focused surcharge that functions as a de facto wealth tax on real estate.

AIMI — Adicional ao Imposto Municipal sobre Imóveis

The Additional Municipal Property Tax (AIMI) was introduced in 2017 as a replacement for Portugal's former stamp-duty-based wealth tax. In 2025/2026 the rules are:

  • Scope: Applies to the taxable patrimonial value (VPT) of Portuguese residential and building-land properties owned on 1 January of each year.
  • Taxpayers: Individuals and companies owning qualifying Portuguese real estate.
  • Allowance for individuals: €600,000 per taxpayer (€1,200,000 for married couples filing jointly).

AIMI rates for individuals:

Taxable VPT Above Allowance (€) Rate
Up to €1,000,000 0.7%
Over €1,000,000 1.0%
  • Companies: A flat 0.4% with no allowance (or 7.5% if the property is held through an entity domiciled in a blacklisted jurisdiction).
  • Married couples filing jointly can opt for combined assessment, which doubles the allowance but applies a slightly different rate schedule (0.7% up to €2,000,000 above allowance; 1.0% thereafter).

What Portugal Does Not Tax

Critically, the following assets fall outside any Portuguese wealth tax or surcharge:

  • Bank deposits and cash
  • Listed and unlisted shares, bonds, and funds
  • Vehicles, art, jewellery, and other movable assets
  • Real estate located outside Portugal (for AIMI purposes)

This is a fundamental distinction from Spain, where virtually all asset classes are included in the wealth tax base.

Use our Portugal Wealth Tax Calculator to estimate your AIMI liability on Portuguese property.

Practical Example: Portugal

Scenario: João is a Portuguese tax resident with total worldwide net assets of €4,000,000. His Portuguese property portfolio has a combined VPT of €2,000,000. He also holds €2,000,000 in equities and bank deposits.

  1. AIMI taxable base: €2,000,000 (property VPT) − €600,000 (individual allowance) = €1,400,000
  2. AIMI calculation:
    • First €1,000,000 at 0.7% = €7,000
    • Remaining €400,000 at 1.0% = €4,000
  3. Total AIMI: €11,000
  4. Wealth tax on equities and deposits: €0 (no such tax exists in Portugal)

João's total wealth-related tax bill is €11,000 — and it applies exclusively to his Portuguese real estate.

Spain vs Portugal Wealth Tax: Head-to-Head Comparison

Here's a side-by-side summary to help you see which country has lower wealth tax at a glance:

Feature Spain (2025/2026) Portugal (2025/2026)
Broad net wealth tax? Yes — Patrimonio + Solidarity Tax No — only property surcharge (AIMI)
Asset classes taxed All (property, shares, cash, art, etc.) Portuguese real estate only
Tax-free allowance €700,000 (+ €300,000 primary home) €600,000 per individual (AIMI)
Top marginal rate 3.5% (over ~€10.7M) 1.0% (over €1.6M VPT)
Regional variation Significant (Madrid vs Catalonia, etc.) Uniform nationwide
Non-residents taxed? Yes, on Spanish-situs assets Yes, on Portuguese property (AIMI)
Worldwide assets for residents? Yes No (only Portuguese property for AIMI)

Key takeaway: For individuals whose wealth is concentrated in financial assets (shares, bonds, bank accounts), Portugal is dramatically more favourable — it simply does not tax them. Spain, by contrast, captures everything in its wealth tax net.

For those with significant real estate holdings in the country of residence, Portugal's AIMI rates (0.7%–1.0%) are generally lower than Spain's regular wealth tax rates at comparable levels, although Spain's primary-residence exemption softens the blow on the family home.

The NHR / IFICI Factor: Portugal's Special Tax Regimes

Portugal's attractiveness goes beyond the absence of a broad wealth tax. The country offers special tax regimes for new residents:

IFICI (Incentivo Fiscal à Investigação Científica e Inovação) — The New NHR

Following the phase-out of the original Non-Habitual Resident (NHR) regime in 2024, Portugal introduced the IFICI regime. While primarily an income tax incentive (offering a flat 20% rate on qualifying Portuguese-source employment and professional income for up to 10 years), it reinforces Portugal's appeal by:

  • Not introducing any new wealth tax obligations.
  • Providing potential exemptions on certain foreign-source income, reducing the overall tax burden for internationally mobile individuals.

Spain has the Beckham Law (Special Expatriate Regime), which caps income tax at a flat 24% on Spanish-source income up to €600,000 for qualifying new arrivals — but it does not exempt them from wealth tax on Spanish assets (and since 2022, Spanish-situs assets are included for Solidarity Tax purposes).

Common Mistakes and Misconceptions

When comparing wealth taxes in Spain and Portugal, people frequently stumble on these points:

1. "Madrid has no wealth tax, so Spain is just as good as Portugal."

This was closer to the truth before 2023. The Solidarity Tax now ensures that no Spanish region offers a full escape from wealth taxation for assets above €3,000,000. Madrid residents with very large fortunes still face 1.7%–3.5% Solidarity Tax rates.

2. "Portugal has no wealth tax at all."

Strictly speaking, Portugal has no tax labelled as a "wealth tax," but AIMI functions as one for real estate owners. If you hold €5 million worth of Portuguese property, your AIMI bill will be material.

3. Ignoring regional differences within Spain

The difference between living in Madrid and Barcelona can be tens of thousands of euros in annual wealth tax. Always model your liability at the regional level, not just the state level.

4. Forgetting the combined income + wealth tax cap in Spain

Spain applies a combined cap: the sum of income tax and wealth tax (at the state level) generally cannot exceed 60% of taxable income. If it does, the wealth tax bill can be reduced — but never by more than 80%. This cap is complex and can actually limit the benefit for those with low income but high wealth.

5. Overlooking double taxation treaties

Spain and Portugal have a bilateral double taxation agreement (DTA), and each country also has DTAs with dozens of other nations. If you own assets in multiple countries, treaty provisions on wealth tax (where they exist) can prevent double taxation. However, many modern DTAs do not include a specific wealth tax article, so professional advice is essential.

Frequently Asked Questions

Q: Which country has lower wealth tax, Spain or Portugal? A: For most asset profiles, Portugal imposes significantly lower wealth-related taxes. Portugal only levies AIMI on Portuguese real estate (at 0.7%–1.0%), while Spain taxes all worldwide net assets of residents at progressive rates up to 3.5%.

Q: Do non-residents pay wealth tax in Spain? A: Yes. Non-residents with assets located in Spain (primarily real estate, but also other Spanish-situs assets) are subject to Spain's wealth tax and, if applicable, the Solidarity Tax on amounts above €3,000,000.

Q: Is Portugal's AIMI deductible against income tax? A: AIMI paid by individuals is not deductible against Portuguese personal income tax (IRS). However, for companies, AIMI is generally deductible as a business expense.

Q: Can I avoid Spain's wealth tax by placing assets in a company? A: Not easily. Spanish wealth tax rules include anti-avoidance provisions, and shares in companies (including holding companies) are valued and included in the taxpayer's net wealth calculation. Professional structuring advice is critical.

Q: What happens if I split my time between both countries? A: Your tax residency determines which country taxes your worldwide assets. Under both Spanish and Portuguese domestic law, you're generally resident if you spend more than 183 days in the country during a calendar year, or if your centre of vital interests is located there. The Spain-Portugal DTA contains tie-breaker rules if you could be considered resident in both.

Conclusion: Key Takeaways for 2025/2026

Here's the bottom line of the Spain Portugal wealth tax comparison:

  1. Portugal is the clear winner for HNWI-friendly wealth taxation. With no broad-based wealth tax on financial assets, Portugal only charges AIMI on Portuguese real estate — and at relatively modest rates.
  2. Spain's wealth tax is comprehensive and getting stricter. The Solidarity Tax has closed the Madrid loophole for fortunes above €3 million, and rates can reach 3.5%.
  3. Your asset mix matters enormously. If your wealth is in stocks, bonds, and bank accounts, Portugal's advantage is massive. If it's concentrated in local real estate, the gap narrows.
  4. Regional choices within Spain still matter — living in Madrid vs. Catalonia can make a five-figure annual difference in wealth tax.
  5. Always model both income tax and wealth tax together. Spain's 60% combined cap and Portugal's IFICI/NHR regimes can shift the overall picture. Use our Spain Wealth Tax Calculator and Portugal Wealth Tax Calculator to run the numbers for your specific situation.
  6. Seek professional advice before making a move, especially if you have complex cross-border holdings or are considering corporate structuring.

Whichever side of the border you choose, understanding the wealth tax landscape before you arrive is the single best financial decision you can make.
