If you own property in Portugal — or you're considering investing in Portuguese real estate — understanding the Portugal wealth tax is essential for accurate financial planning. Unlike many European countries that impose broad-based wealth taxes on net assets, Portugal's approach is more targeted: it applies an additional property tax called AIMI (Adicional ao Imposto Municipal sobre Imóveis) on high-value real estate holdings.
In this complete guide for the 2025/2026 tax year, we'll break down everything you need to know about the wealth tax in Portugal, including current rates, thresholds, exemptions, filing deadlines, and practical examples to help you estimate your liability. Whether you're a Portuguese resident, a non-resident investor, or an expat relocating to Portugal, this article will give you the clarity you need.
What Is the Portugal Wealth Tax (AIMI)?
Portugal does not have a traditional wealth tax that applies to all personal assets such as bank accounts, investments, and valuables. Instead, Portugal levies the AIMI — an additional municipal property tax — which functions as a wealth tax on real estate.
Introduced in 2017, AIMI was designed to replace the old Stamp Duty surcharge on high-value properties. It applies to the taxable patrimonial value (Valor Patrimonial Tributário, or VPT) of Portuguese residential and building land properties that exceed certain thresholds.
Key Features of AIMI
- Tax base: The combined taxable patrimonial value (VPT) of all urban residential properties and building plots owned in Portugal.
- Assessment date: Property ownership is assessed as of January 1 of each year.
- Taxpayers: Individuals (residents and non-residents), married couples (with optional joint taxation), and corporate entities owning Portuguese property.
- Exclusions: Commercial, industrial, and service-related properties are generally excluded from AIMI. Rural properties are also excluded.
AIMI is levied in addition to the standard annual municipal property tax (IMI — Imposto Municipal sobre Imóveis), which applies at rates of 0.3%–0.45% for urban properties and 0.8% for rural properties.
Portugal Wealth Tax Rates and Thresholds for 2025/2026
The Portugal tax rates for 2025/2026 under AIMI follow a progressive structure for individuals and a flat structure for corporate owners. Understanding these brackets is crucial for calculating your liability.
AIMI Rates for Individuals
| Taxable Patrimonial Value (VPT) | AIMI Rate |
|---|---|
| Up to €600,000 | 0% (exempt) |
| €600,001 to €1,000,000 | 0.7% |
| Over €1,000,000 | 1.0% |
For married couples or civil partners who elect joint taxation, the exemption threshold doubles to €1,200,000. The same rate brackets apply to the combined VPT above that threshold.
AIMI Rates for Corporate Entities
| Ownership Type | AIMI Rate |
|---|---|
| Standard corporate ownership | 0.4% |
| Properties held by entities in blacklisted jurisdictions (tax havens) | 7.5% |
Corporate entities do not benefit from any exemption threshold — the 0.4% rate applies to the entire VPT of all qualifying properties from the first euro. This is a critical distinction that makes holding high-value property through a company potentially more expensive for moderate portfolios, but sometimes beneficial for very high-value holdings depending on the circumstances.
Important Note on the Marginal System
For individuals, AIMI operates on a marginal basis, similar to income tax brackets. This means only the portion of VPT that exceeds each threshold is taxed at the higher rate. The first €600,000 (or €1,200,000 for couples opting for joint taxation) is always exempt.
How to Calculate Your Portugal Wealth Tax Liability
Calculating your AIMI liability involves several steps. Let's walk through the process with practical examples.
Step 1: Determine Your Total Taxable Patrimonial Value
Add up the VPT of all urban residential properties and building plots you own in Portugal as of January 1. The VPT is not the market value — it's the fiscal value assigned by the Portuguese tax authority (Autoridade Tributária e Aduaneira) and recorded in the property tax register (Caderneta Predial).
Step 2: Apply the Exemption Threshold
- Individual taxpayer: Subtract €600,000 from your total VPT.
- Married couple (joint taxation): Subtract €1,200,000 from the combined VPT.
If the result is zero or negative, you owe no AIMI.
Step 3: Apply the Marginal Rates
Apply 0.7% to the portion between €600,001 and €1,000,000, and 1.0% to any amount above €1,000,000.
Practical Example 1: Individual Owner
Scenario: Maria is a Portuguese resident who owns two apartments with a combined VPT of €850,000.
- Exempt amount: €600,000
- Taxable amount: €850,000 − €600,000 = €250,000
- AIMI due: €250,000 × 0.7% = €1,750
Practical Example 2: Married Couple (Joint Taxation)
Scenario: João and Ana are married and jointly own properties with a total VPT of €1,500,000. They opt for joint AIMI taxation.
- Exempt amount: €1,200,000
- Taxable amount at 0.7%: €1,000,000 × 2 (doubled threshold for couple at 0.7% band) — actually, let's recalculate correctly under the marginal system for couples:
- The thresholds for couples double: exempt up to €1,200,000, the 0.7% band applies from €1,200,001 to €2,000,000, and 1.0% applies above €2,000,000.
- Taxable at 0.7%: €1,500,000 − €1,200,000 = €300,000
- AIMI due: €300,000 × 0.7% = €2,100
Practical Example 3: Corporate Owner
Scenario: A Portuguese limited company (Lda.) owns residential properties with a total VPT of €800,000.
- No exemption threshold for companies.
- AIMI due: €800,000 × 0.4% = €3,200
Notice that in Example 1, Maria's individual AIMI on €850,000 is just €1,750, while the corporate rate on €800,000 yields €3,200. This illustrates why holding moderate-value property through a company can be more expensive from an AIMI perspective.

AIMI Exemptions and Deductions
Several exemptions and deductions can reduce or eliminate your Portugal wealth tax liability.
Property Type Exemptions
- Commercial, industrial, and service properties are excluded from AIMI.
- Rural properties are excluded.
- Properties exempt from IMI (e.g., properties owned by the state, recognized charities, or properties with temporary IMI exemptions for urban rehabilitation) are generally also exempt from AIMI.
Personal Deductions
- Mortgage interest deduction: Individual taxpayers can deduct mortgage loan payments (capital and interest) related to the acquisition of their primary residence from the taxable VPT, but only for properties that were acquired with bank financing. This deduction is capped and applies under specific conditions.
- Joint taxation election: Married couples and civil partners can elect to be taxed jointly, effectively doubling the exemption threshold from €600,000 to €1,200,000.
AIMI as a Deduction Against Income Tax
Individual taxpayers who are subject to AIMI can deduct the AIMI amount paid from their IRS (personal income tax) liability, specifically against rental income (Category F) or capital gains from property (Category G). This is an important planning consideration. If you earn rental income from Portuguese property, the AIMI paid can offset part of your income tax bill.

Filing and Payment Deadlines
Unlike IMI, which is calculated and issued automatically by the tax authority, AIMI has its own assessment and payment timeline.
Key Dates for 2025/2026
- Assessment date: January 1, 2025 (for the 2025 AIMI tax year). Ownership on this date determines liability.
- Tax assessment notice: Typically issued by the tax authority in June.
- Payment deadline: AIMI is generally due in a single payment in September of the corresponding year. Unlike IMI, which can be split into installments, AIMI must be paid in one lump sum.
- Joint taxation election deadline: Married couples who wish to opt for joint AIMI taxation must make this election between April 1 and May 31 through the Portuguese tax authority's online portal (Portal das Finanças).
How to Pay
AIMI is paid through the Portuguese tax authority's online portal, by ATM (Multibanco), or at a local tax office (Serviço de Finanças). Non-residents can manage their obligations through the portal or by appointing a fiscal representative in Portugal.
AIMI for Non-Residents and Foreign Investors
The wealth tax in Portugal applies equally to residents and non-residents. If you own qualifying property in Portugal, you are subject to AIMI regardless of your tax residency.
Key Considerations for Non-Residents
- Fiscal representative requirement: Non-residents from outside the EU/EEA who own property in Portugal are generally required to appoint a fiscal representative (representante fiscal) in Portugal. This person acts as a liaison with the tax authority.
- Same rates and thresholds: Non-residents benefit from the same €600,000 individual exemption and the same marginal rates as residents.
- Double taxation treaties: Portugal has an extensive network of double taxation agreements (DTAs) with over 70 countries, including the United States, United Kingdom, Canada, Brazil, Germany, France, and many others. While these treaties primarily address income tax (including rental income and capital gains from property), they generally do not cover property taxes like AIMI directly. However, in some cases, AIMI paid can reduce the income tax base (as mentioned above), which may indirectly interact with treaty provisions.
- NHR and tax incentives: Portugal's former Non-Habitual Resident (NHR) regime, which offered favorable income tax rates for qualifying new residents, has been largely discontinued for new applicants as of 2024, replaced by a more limited incentive for scientific research and innovation. However, NHR status does not exempt holders from AIMI — property tax obligations remain regardless of NHR status.
Holding Property Through a Foreign Company
If a foreign company owns Portuguese residential property, AIMI applies at the 0.4% corporate rate with no exemption threshold. If the company is registered in a jurisdiction classified as a tax haven by Portugal (listed in Portaria 150/2004 and subsequent amendments), the punitive rate of 7.5% applies. This is a critical consideration for international structuring.
Common Mistakes and Misconceptions
Navigating the Portugal wealth tax system can be tricky. Here are the most common pitfalls:
1. Confusing VPT with Market Value
The taxable patrimonial value (VPT) is often significantly lower than the market value of a property. Many property owners overestimate their AIMI liability by using market values. Always check the VPT on your Caderneta Predial through the Portal das Finanças.
2. Forgetting to Elect Joint Taxation
Married couples who fail to submit the joint taxation election by the May 31 deadline are taxed individually by default. This means each spouse gets only a €600,000 exemption on their share of property, rather than sharing a combined €1,200,000 exemption. For couples who own property jointly, this can result in a higher tax bill.
3. Assuming Companies Always Save Tax
While the corporate AIMI rate (0.4%) is lower than the individual marginal rates (0.7%–1.0%), companies receive no exemption threshold. For property portfolios with a VPT below approximately €1.5 million, individual ownership often results in lower AIMI than corporate ownership.
4. Ignoring the AIMI Deduction Against Income Tax
Many taxpayers overlook the fact that AIMI paid can be deducted against property-related income tax. If you earn rental income, failing to claim this deduction means you're effectively paying more tax than necessary.
5. Overlooking the Assessment Date
AIMI liability is determined by ownership on January 1. If you sell a property on January 2, you are still liable for that year's AIMI. Timing property transactions with this date in mind can have significant tax implications.
