Buying, owning, or selling property in Portugal comes with a set of tax obligations that every homeowner and investor should understand. Whether you are a Portuguese resident, an expat settling on the Algarve coast, or a non-resident investor eyeing Lisbon's rental market, understanding how Portugal property tax works is essential to making smart financial decisions.
In this comprehensive guide, we break down every property tax you will encounter in Portugal for the 2025/2026 tax year—from the annual municipal property tax (IMI) to the transfer tax (IMT), stamp duty, and the additional surcharge on high-value properties (AIMI). We also cover exemptions, payment deadlines, and common mistakes to avoid.
Use our Portugal Property Tax Calculator to quickly estimate your annual IMI liability based on your property's tax value.
Overview of Property Taxes in Portugal
Portugal's property tax system is composed of several distinct taxes, each triggered at a different stage of property ownership:
- IMI (Imposto Municipal sobre Imóveis) – The annual municipal property tax paid by all property owners.
- IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis) – A one-off transfer tax paid when purchasing property.
- Imposto do Selo (Stamp Duty) – A stamp duty charged on the property purchase transaction.
- AIMI (Adicional ao IMI) – An additional annual wealth-style surcharge on owners of high-value property portfolios.
Each of these taxes uses the Valor Patrimonial Tributário (VPT)—the tax assessment value of the property—as its calculation base. The VPT is determined by the Portuguese Tax Authority (Autoridade Tributária e Aduaneira) and is often significantly lower than the market value.
IMI: Portugal's Annual Municipal Property Tax Explained
IMI is the core property tax in Portugal that every owner pays each year. It is levied by the local municipality (câmara municipal) where the property is located.
How IMI Is Calculated
The formula is straightforward:
IMI = VPT × IMI Rate
The VPT is reassessed periodically by the tax authority using factors such as location, age, size, quality, and intended use of the property.
IMI Rates for 2025/2026
IMI rates are set by each municipality within legally established bands:
| Property Type | Minimum Rate | Maximum Rate |
|---|---|---|
| Urban properties | 0.3% | 0.45% |
| Rural properties | 0.8% | 0.8% |
| Properties owned by entities in blacklisted jurisdictions | 7.5% | 7.5% |
Most municipalities set their urban rate between 0.3% and 0.4%. Lisbon and Porto, for example, apply rates of 0.3%.
Municipalities can also apply surcharges or discounts:
- A discount of up to 20% for families with dependents.
- A surcharge of up to 30% for properties that have been vacant for more than one year.
- Properties not revalued for over three years may face a VPT uplift.
Practical Example: Calculating IMI
Imagine you own an apartment in Lisbon with a VPT of €150,000 and the municipality applies a rate of 0.3%:
IMI = €150,000 × 0.3% = €450 per year
If the same property were in a smaller municipality applying 0.45%:
IMI = €150,000 × 0.45% = €675 per year

IMI Payment Deadlines
IMI is assessed based on ownership on 31 December of the preceding year and is paid in the following year:
- Up to €100: Single payment in May.
- €100 to €500: Two installments in May and November.
- Over €500: Three installments in May, August, and November.
Payments can be made through the Portuguese Tax Authority's portal (Portal das Finanças), at ATM machines (Multibanco), or by direct debit.
IMT: The Property Transfer Tax
IMT is a one-off tax paid by the buyer at the time of purchasing property in Portugal. It is one of the most significant upfront costs and must be paid before the deed (escritura) is signed.
How IMT Is Calculated
IMT is calculated on the higher of two values: the declared purchase price or the VPT. Portugal uses a progressive rate system for residential property.
IMT Rates for Permanent Residence (Continental Portugal) – 2025/2026
| Taxable Value (€) | Marginal Rate | Deduction (€) |
|---|---|---|
| Up to 101,917 | 0% | 0 |
| 101,917 – 139,412 | 2% | 2,038.34 |
| 139,412 – 190,086 | 5% | 6,220.70 |
| 190,086 – 316,772 | 7% | 10,022.42 |
| 316,772 – 633,453 | 8% | 13,189.14 |
| 633,453 – 1,102,920 | 6% (flat on total) | — |
| Over 1,102,920 | 7.5% (flat on total) | — |
Note: For secondary/holiday homes or non-habitual residences, the brackets are lower and rates start sooner. For non-residential/commercial property, a flat rate of 6.5% applies. Properties in Madeira and the Azores benefit from reduced rates.
Practical Example: Calculating IMT
You purchase a primary residence in Porto for €250,000 (and the VPT is lower than this):
IMT = (€250,000 × 7%) – €10,022.42 = €17,500 – €10,022.42 = €7,477.58
If the same property were a second home, the applicable rates would be higher, and the exempt threshold would be lower (€0 for the first bracket).
IMT Exemptions
- Properties purchased for permanent residence with a value up to €101,917 are exempt from IMT (continental Portugal).
- Certain urban rehabilitation properties may qualify for IMT exemptions.
- Properties acquired by real estate investment funds may benefit from reduced rates.
Stamp Duty (Imposto do Selo) on Property
In addition to IMT, buyers must pay stamp duty at a flat rate of 0.8% on the higher of the purchase price or the VPT.
Using the same €250,000 Porto example:
Stamp Duty = €250,000 × 0.8% = €2,000
Stamp duty is also payable on mortgage financing at a rate of 0.6% for loans with terms over five years (or 0.5% for shorter terms), calculated on the loan amount.
Combined upfront tax cost for our €250,000 example (with a €200,000 mortgage over 25 years):
| Tax | Amount |
|---|---|
| IMT | €7,477.58 |
| Stamp Duty (property) | €2,000.00 |
| Stamp Duty (mortgage) | €1,200.00 |
| Total | €10,677.58 |
AIMI: The Additional Property Tax for High-Value Portfolios
The Adicional ao IMI (AIMI) is a wealth-style surcharge applied to property owners whose total VPT of urban properties exceeds certain thresholds. It was introduced in 2017 and remains in force for 2025/2026.
AIMI Thresholds and Rates for Individuals
| Total VPT of Urban Properties | Rate |
|---|---|
| Up to €600,000 | Exempt |
| €600,000 – €1,000,000 | 0.7% (on amount exceeding €600,000) |
| Over €1,000,000 | 1.0% (on amount exceeding €1,000,000) + 0.7% on the €600k–€1M band |
For married couples filing jointly, the exempt threshold doubles to €1,200,000.
For companies, a flat rate of 0.4% applies to the entire VPT (no exempt threshold), rising to 0.7% for properties held by entities in blacklisted jurisdictions. Companies can opt for a "subject-to-individual-rules" regime under certain conditions.
Practical Example: AIMI for an Individual
You own three apartments in Lisbon with a combined VPT of €800,000:
AIMI = (€800,000 – €600,000) × 0.7% = €200,000 × 0.7% = €1,400
AIMI is assessed in June and payable in September each year.
Property Tax Exemptions and Reductions in Portugal
Portugal offers several exemptions and reductions that can significantly lower your property tax burden:
Temporary IMI Exemption for New Owners
- Properties purchased for permanent residence with a VPT up to €125,000 qualify for a three-year IMI exemption.
- The owner's household income (rendimento bruto) must not exceed €153,300 in the year prior to purchase.
- The exemption is automatic if conditions are met, but it is advisable to confirm with the tax authority.
Urban Rehabilitation Exemptions
- Properties undergoing certified urban rehabilitation may be exempt from IMI for three to five years, extendable in some cases.
- IMT exemptions may also apply to rehabilitated properties.
Family-Related Discounts
- Municipalities may reduce IMI by up to 20% depending on the number of dependents in the household.
Heritage and Cultural Properties
- Properties classified as national monuments or of public interest may qualify for IMI exemptions.
Property Tax for Non-Residents in Portugal
Non-residents who own property in Portugal are subject to the same IMI, AIMI, and stamp duty rules as residents. However, there are some important nuances:
- IMT rates for non-residents purchasing a non-primary residence are typically higher because the primary-residence brackets (with the higher exempt threshold) only apply if the buyer intends to make the property their permanent home.
- Rental income earned by non-residents is taxed at a flat rate of 25% (or 28% for certain types). This is separate from property tax but is an important consideration. Use our Portugal Income Tax Calculator to understand your overall tax position.
- Double taxation treaties: Portugal has treaties with over 70 countries. These can provide relief on property income if you are also taxed in your country of residence. Check whether your home country offers credits for Portuguese property taxes paid.
- Fiscal representative: Non-residents from outside the EU/EEA were previously required to appoint a fiscal representative in Portugal. Since 2022, this requirement has been relaxed for EU/EEA residents, but non-EU owners should still consider appointing one for practical purposes.
Common Mistakes Non-Residents Make
- Failing to register with the Portuguese tax authority – You need a Portuguese tax number (NIF) before purchasing.
- Missing IMI payment deadlines – Notifications are sent to the fiscal address on file; if you don't update it, you may miss payments and incur penalties.
- Not claiming the correct IMT bracket – Buyers sometimes pay the secondary-home IMT rate when they qualify for the primary-residence rate (or vice versa).
- Overlooking AIMI – Non-residents with multiple properties may not realize the AIMI surcharge applies to them.
Frequently Asked Questions (FAQ)
Is property tax in Portugal expensive compared to other European countries?
Portugal's property tax rates are relatively moderate. IMI rates of 0.3%–0.45% on the VPT (which is often well below market value) tend to result in lower annual bills than equivalent properties in countries like France, Spain, or the UK. However, the upfront IMT transfer tax can be significant.
How do I find my property's VPT?
You can check your property's VPT on the Portal das Finanças (the Portuguese tax authority's online portal) under the "Património" section. You will need your NIF and access credentials.
Can I contest my property's VPT?
Yes. If you believe the VPT is too high, you can request a reassessment (pedido de segunda avaliação) within 30 days of being notified of the valuation. An independent panel will re-evaluate the property.
Do I pay property tax when selling a property in Portugal?
The seller does not pay IMI or IMT on the sale itself. However, the seller may be liable for capital gains tax on the profit. Residents are taxed on 50% of the gain at their marginal income tax rate, while non-residents pay a flat 28% on the full gain (subject to EU/EEA special rules and treaty provisions).
Are there any changes expected for 2026?
The Portuguese government periodically adjusts IMT brackets, IMI exemption thresholds, and AIMI rules through the annual State Budget (Orçamento do Estado). While no major structural overhaul has been announced for 2026, it is prudent to check the latest budget updates or consult a tax advisor.
