If you own property in Portugal or are considering investing in Portuguese real estate, understanding the Portugal wealth tax explained in plain language is essential for your financial planning. Unlike many European countries that have abolished broad-based wealth taxes, Portugal maintains a targeted wealth tax known as AIMI (Adicional ao Imposto Municipal sobre Imóveis), which applies specifically to high-value real estate holdings.
In this comprehensive guide, we'll break down how wealth tax works in Portugal for the 2025/2026 tax year, including current rates, thresholds, exemptions, and practical strategies to manage your tax liability. Whether you're a resident, non-resident, or expat relocating to Portugal, this article covers everything you need to know.
What Is Portugal's Wealth Tax (AIMI)?
Portugal's wealth tax is officially called the Adicional ao Imposto Municipal sobre Imóveis (AIMI), which translates to the "Additional Municipal Property Tax." Introduced in 2017, AIMI replaced the old Imposto do Selo (Stamp Duty) surcharge on high-value properties and serves as Portugal's de facto wealth tax.
Here's what makes AIMI distinctive:
- It targets real estate wealth only — unlike wealth taxes in countries such as Spain or Norway, Portugal does not tax financial assets, investments, vehicles, art, or other movable property.
- It applies to the taxable value (VPT) of Portuguese residential and building land properties registered in the taxpayer's name as of January 1 of each year.
- It is levied in addition to the standard annual municipal property tax (IMI — Imposto Municipal sobre Imóveis).
In essence, AIMI functions as a supplementary property tax that kicks in once the total taxable value of your Portuguese property portfolio exceeds certain thresholds.
AIMI vs. IMI: What's the Difference?
It's important not to confuse AIMI with IMI. Here's a quick comparison:
| Feature | IMI (Municipal Property Tax) | AIMI (Wealth Tax) |
|---|---|---|
| Applies to | All property owners | Property owners above threshold |
| Tax base | Individual property VPT | Aggregate VPT of all qualifying properties |
| Rates | 0.3%–0.45% (urban); 0.8% (rural) | 0.4%–1.5% (see below) |
| Threshold | No minimum threshold | €600,000 per individual |
| Administered by | Municipal authorities | National tax authority (AT) |
Both taxes use the Valor Patrimonial Tributário (VPT) — the tax-assessed value of the property — as the tax base, which is often significantly lower than the market value.
Wealth Tax Rates in Portugal for 2025/2026
Understanding the wealth tax rates Portugal applies is crucial for calculating your liability. The AIMI rate structure depends on the type of taxpayer and the total VPT of qualifying properties.
Rates for Individual Taxpayers
For individuals, AIMI applies to the aggregate VPT of all qualifying residential properties and building land owned as of January 1, after deducting a personal allowance:
- Personal allowance: €600,000 per taxpayer
- Married couples (joint taxation option): €1,200,000 combined allowance
| Taxable VPT (after deduction) | AIMI Rate |
|---|---|
| Up to €1,000,000 | 0.7% |
| Above €1,000,000 | 1.0% |
Important: For properties held by individuals with a total VPT exceeding €2,000,000 (after the €600,000 deduction), a marginal rate of 1.5% may apply to the excess portion, depending on the specific legislative provisions in force.
Rates for Corporate Taxpayers
Companies and other legal entities that own qualifying Portuguese property are subject to different rules:
- Standard rate: 0.4% on the total VPT (no deduction/threshold)
- Properties held by entities in blacklisted jurisdictions: 7.5% on the total VPT
Notably, companies do not benefit from any personal allowance or threshold. AIMI applies from the first euro of VPT, which is a critical consideration for those holding property through corporate structures.
Married Couples: Joint vs. Separate Taxation
Married couples or civil partners can choose between:
- Separate taxation: Each spouse uses their own €600,000 deduction against properties held in their individual name. Jointly owned properties are split 50/50.
- Joint taxation: The couple combines their properties and benefits from a €1,200,000 deduction, with rates applied to the combined excess.
The optimal choice depends on how property ownership is structured between spouses. Use our Portugal Wealth Tax Calculator to model both scenarios and determine which saves you more.
How to Calculate Your AIMI Liability: A Step-by-Step Guide
Let's walk through how wealth tax works in Portugal with a practical calculation:
Step 1: Identify Qualifying Properties
AIMI applies to:
- ✅ Residential properties (urban buildings classified as "habitação")
- ✅ Building land (terrenos para construção)
AIMI does not apply to:
- ❌ Commercial, industrial, or service-use properties
- ❌ Rural properties
- ❌ Properties classified as public infrastructure
Step 2: Determine the Total VPT
Add up the VPT of all qualifying properties you own as of January 1, 2025. You can find the VPT on your Caderneta Predial (property tax document) or through the Portuguese tax authority's online portal.
Step 3: Apply the Deduction
Subtract your personal allowance:
- Individual: €600,000
- Married (joint election): €1,200,000
- Company: €0 (no deduction)
Step 4: Apply the Rates
Apply the marginal AIMI rates to the remaining amount.
Practical Example: Individual Taxpayer
Scenario: Maria owns three apartments in Lisbon with a combined VPT of €950,000.
| Step | Calculation | Amount |
|---|---|---|
| Total VPT | — | €950,000 |
| Less: Personal deduction | — | -€600,000 |
| Taxable amount | €950,000 - €600,000 | €350,000 |
| AIMI at 0.7% | €350,000 × 0.7% | €2,450 |
Maria's AIMI liability for 2025 is €2,450, payable in addition to her regular IMI on each property.
Practical Example: Corporate Ownership
Scenario: A Portuguese company (Sociedade Limitada) owns the same three properties with a combined VPT of €950,000.
| Step | Calculation | Amount |
|---|---|---|
| Total VPT | — | €950,000 |
| Less: Deduction | None for companies | €0 |
| Taxable amount | — | €950,000 |
| AIMI at 0.4% | €950,000 × 0.4% | €3,800 |
Despite the lower corporate rate (0.4% vs. 0.7%), the company pays €3,800 because no deduction applies. This demonstrates that holding property personally can sometimes be more tax-efficient — though corporate structures may offer other advantages.

Payment Deadlines and Administration
AIMI follows a specific annual cycle that property owners should mark on their calendar:
- Reference date: January 1 — AIMI is based on property ownership and VPT as of this date.
- Assessment: The Portuguese tax authority (Autoridade Tributária e Aduaneira, or AT) calculates AIMI automatically based on property records.
- Payment deadline: AIMI is typically due in September of the same year. For 2025, expect the payment notice in September 2025.
- Payment method: Through the AT's online portal, at ATM machines (Multibanco), or at authorized payment locations.
Unlike IMI, which can be split into installments, AIMI is generally payable in a single lump sum.
What Happens If You Don't Pay?
Failure to pay AIMI by the deadline results in:
- Late payment interest (juros de mora)
- Potential enforcement proceedings (processo de execução fiscal)
- A tax lien on the property
Exemptions and Special Situations
Several exemptions and special rules affect how AIMI is applied:
Properties Exempt from AIMI
- Properties exempt from IMI are generally also exempt from AIMI. This includes properties owned by the state, charitable organizations, and certain heritage-classified buildings.
- Commercial and industrial properties are not subject to AIMI regardless of value.
- Properties held by collective investment vehicles (such as Portuguese real estate investment funds — fundos de investimento imobiliário) may be subject to special rules.
Non-Habitual Resident (NHR) Regime
The NHR regime, which was largely closed to new applicants from 2024 onward (replaced by the new tax incentive for scientific research and innovation — IFICI), did not provide any exemption from AIMI. Property owners under the NHR or the new IFICI regime are fully subject to AIMI on qualifying Portuguese properties.
Non-Residents
Non-residents who own qualifying property in Portugal are subject to AIMI under the same rules as residents. If you own property individually, you benefit from the same €600,000 deduction. If you hold property through a foreign company, the 0.4% rate applies with no deduction — or 7.5% if the entity is domiciled in a blacklisted jurisdiction.
AIMI as a Deduction Against Income Tax
An important planning consideration: AIMI paid by individuals can, in certain circumstances, be deducted against Portuguese income tax (IRS) on rental income from the same properties. This means that if your Portuguese properties generate taxable rental income, AIMI may partially offset your income tax liability.

Common Mistakes and Misconceptions
When navigating Portugal's wealth tax, taxpayers frequently encounter these pitfalls:
1. Confusing VPT with Market Value
The VPT is the tax-assessed value, not the market price. In Lisbon and Porto, market values often exceed VPT by 50–200%. This means your AIMI liability may be lower than you expect based on purchase prices. However, the tax authority periodically updates VPTs, so this gap can narrow over time.
2. Assuming Corporate Ownership Always Saves Tax
As our examples showed, the absence of a personal deduction for companies can make corporate ownership more expensive from an AIMI perspective, even though the rate is lower. Always model both scenarios before restructuring ownership.
3. Forgetting About Joint Ownership Rules
If you co-own property with your spouse, the VPT is split according to ownership shares for separate taxation purposes. Failing to elect joint taxation when it's beneficial — or electing it when it's not — can cost hundreds or thousands of euros.
4. Overlooking the January 1 Reference Date
AIMI liability is determined by ownership on January 1. If you sell a property on January 2, you're still liable for the full year's AIMI. Timing property transactions around this date can be strategically important.
5. Ignoring Double Taxation Relief
Non-residents should check whether their home country offers a credit or deduction for property taxes paid in Portugal. Portugal has double taxation agreements (DTAs) with over 79 countries, including all EU member states, the United States, the United Kingdom, Canada, and Brazil. While AIMI is a property-based tax (and may not always be directly creditable under DTAs), the interaction with your home country's tax system is worth investigating with a qualified advisor.
Strategies to Minimize Your Portugal Wealth Tax
While tax planning should always be conducted with professional guidance, here are some legitimate approaches to managing AIMI exposure:
- Optimize ownership between spouses: Distribute property ownership and elect joint or separate taxation based on which produces the lower AIMI bill.
- Monitor VPT reassessments: If you believe a property's VPT is inflated, you can request a reassessment from the tax authority. This can reduce both IMI and AIMI.
- Consider property classification: Ensure properties are correctly classified. A property classified as commercial rather than residential would fall outside AIMI's scope.
- Time acquisitions and disposals: Be mindful of the January 1 reference date when planning transactions.
- Evaluate corporate vs. personal ownership holistically: Factor in not just AIMI but also IMI, income tax on rental income, capital gains tax, and succession planning.
Frequently Asked Questions About Portugal's Wealth Tax

You can find your property's VPT on the Caderneta Predial Urbana, available through the Portuguese tax authority's online portal at Portal das Finanças.
When was AIMI introduced?
AIMI was introduced in 2017 as part of Portugal's State Budget Law, replacing the previous Stamp Duty surcharge on high-value properties.
Conclusion: Key Takeaways for 2025/2026
