If you own property in Portugal — or you're planning to buy — understanding Portugal property tax obligations is essential. The Portuguese property tax system involves several different taxes that apply at the point of purchase, during ownership, and even upon sale. For the 2025/2026 tax year, rates and thresholds have been updated, and this guide walks you through every key detail so you can plan your finances with confidence.
Whether you're a Portuguese resident, a non-resident investor, or an expat relocating under Portugal's revised Non-Habitual Resident (NHR) successor regime, this comprehensive guide covers IMI (annual property tax), IMT (transfer tax), stamp duty, the additional AIMI wealth surcharge, capital gains tax on property, available exemptions, and critical payment deadlines.
Use our Portugal Property Tax Calculator to quickly estimate your annual IMI and other property-related tax liabilities.
What Taxes Apply to Property in Portugal?
Portugal's property tax framework is made up of multiple levies. Here's a quick overview of each:
- IMI (Imposto Municipal sobre Imóveis) – The annual municipal property tax, similar to council tax or property tax in other countries.
- IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis) – A one-off transfer tax paid when you purchase or acquire a property.
- Imposto do Selo (Stamp Duty) – A flat-rate stamp duty also payable upon purchase.
- AIMI (Adicional ao IMI) – An additional property tax surcharge for owners of higher-value real estate.
- Capital Gains Tax (Mais-Valias) – Tax on profit when you sell a property.
Understanding each of these taxes — and how they interact — is the key to accurate budgeting when buying or holding property in Portugal.
IMI: Portugal's Annual Property Tax for 2025/2026
IMI is the most important recurring property tax in Portugal. It is levied annually by the municipality where the property is located and is based on the property's Valor Patrimonial Tributário (VPT) — its tax-assessed value determined by the Portuguese Tax Authority (Autoridade Tributária).
IMI Tax Rates for 2025/2026
IMI rates are set by each municipality within ranges defined by national law:
| Property Type | Minimum Rate | Maximum Rate | Typical Rate |
|---|---|---|---|
| Urban properties | 0.3% | 0.45% | 0.3% – 0.4% |
| Rural properties | 0.8% | 0.8% | 0.8% (flat) |
| Properties owned by entities in blacklisted jurisdictions | 7.5% | 7.5% | 7.5% (flat) |
Key points:
- Most municipalities apply rates between 0.3% and 0.4% for urban properties.
- The rate is applied to the VPT, not the market value or purchase price. The VPT is often significantly lower than the actual market value.
- Municipalities can reduce the standard rate by up to 20% for certain taxpayers (e.g., families with dependents) or increase it for long-vacant properties.
- Properties owned by companies registered in tax havens on Portugal's blacklist are subject to a punitive 7.5% IMI rate.
How Is the VPT Calculated?
The VPT is determined using a formula that considers:
- Base construction cost per square meter (updated annually)
- Area of the property (including gross area, dependent areas, and land)
- Location coefficient (higher in Lisbon and the Algarve, lower in rural areas)
- Quality and comfort coefficient (pools, garages, age of the building, etc.)
- Property use coefficient (residential, commercial, etc.)
You can check your property's VPT on the Portuguese Tax Authority's portal (Portal das Finanças). If you believe the assessment is too high, you can request a reassessment.
IMI Payment Deadlines
IMI is calculated based on the property's status on December 31 of the previous year and is payable in the following year:
- Single payment (May): If total IMI is €100 or less.
- Two installments (May and November): If total IMI is between €100 and €500.
- Three installments (May, August, and November): If total IMI exceeds €500.
Payment can be made via direct debit, ATM (Multibanco), the Tax Authority portal, or at a local tax office.
Practical Example: Calculating IMI
Suppose you own an apartment in Lisbon with a VPT of €150,000, and the municipality applies an IMI rate of 0.3%:
Annual IMI = €150,000 × 0.3% = €450
Since the amount is between €100 and €500, you would pay in two installments: €225 in May and €225 in November.

IMT: Property Transfer Tax When Buying in Portugal
IMT is the one-off transfer tax paid by the buyer before the deed of purchase (escritura) is signed. It is one of the largest upfront costs when buying property in Portugal.
IMT Rates for 2025/2026
IMT rates are progressive for residential properties (mainland Portugal) and depend on whether the property is your primary permanent residence or a secondary/investment property.
Permanent Residence (Mainland Portugal)
| 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) | — |
Secondary/Investment Properties (Mainland Portugal)
| Taxable Value (€) | Marginal Rate | Deduction (€) |
|---|---|---|
| Up to 101,917 | 1% | 0 |
| 101,917 – 139,412 | 2% | 1,019.17 |
| 139,412 – 190,086 | 5% | 5,201.53 |
| 190,086 – 316,772 | 7% | 9,003.25 |
| 316,772 – 607,528 | 8% | 12,170.85 |
| 607,528 – 1,102,920 | 6% (flat on total) | — |
| Over 1,102,920 | 7.5% (flat on total) | — |
Note: Properties in the Azores benefit from a 20% reduction in IMT rates. Properties in Madeira follow the mainland rates.
IMT Exemptions
- Properties purchased for permanent residence with a value up to €101,917 are exempt from IMT (mainland).
- Properties for urban rehabilitation may qualify for IMT exemption under specific government programs.
- Purchases by the state, local authorities, or certain public entities are exempt.
Practical Example: IMT Calculation
You're buying a second home in the Algarve for €350,000:
IMT = (€350,000 × 8%) – €12,170.85 = €28,000 – €12,170.85 = €15,829.15
IMT must be paid before the purchase deed is executed. You can obtain the payment slip (guia de pagamento) through the Tax Authority portal.
Stamp Duty (Imposto do Selo) on Property Purchases
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.
If you take out a mortgage, additional stamp duty applies:
- 0.6% on the mortgage value for loans with terms of 5 years or more.
- 0.5% for terms between 1 and 5 years.
Example
For a property purchase at €350,000:
Stamp Duty = €350,000 × 0.8% = €2,800
If you take a 25-year mortgage of €250,000:
Mortgage Stamp Duty = €250,000 × 0.6% = €1,500
Total stamp duty on the transaction = €2,800 + €1,500 = €4,300
AIMI: The Additional Property Tax Surcharge
The Adicional ao IMI (AIMI) is an annual wealth surcharge that applies to property owners whose combined VPT of Portuguese urban properties exceeds certain thresholds.
AIMI Thresholds and Rates for 2025/2026
| Owner Type | Exempt Threshold | Rate on Excess | Higher Rate (VPT > €1,000,000) |
|---|---|---|---|
| Individuals | €600,000 | 0.7% | 1.0% |
| Married couples (joint filing) | €1,200,000 | 0.7% | 1.0% |
| Companies | €600,000 | 0.4% | 0.7% |
| Entities in blacklisted jurisdictions | No exemption | 7.5% | 7.5% |
Key details:
- AIMI is calculated on the sum of VPTs of all urban properties owned by the taxpayer in Portugal.
- The exemption threshold is deducted before applying the rate.
- Married couples can opt to file jointly for AIMI purposes to benefit from the higher €1,200,000 threshold.
- AIMI is payable in June each year.
Practical Example: AIMI Calculation
An individual owns two apartments in Lisbon with combined VPTs of €800,000:
AIMI = (€800,000 – €600,000) × 0.7% = €200,000 × 0.7% = €1,400
Capital Gains Tax on Selling Property in Portugal
When you sell a property in Portugal at a profit, you may be subject to capital gains tax (Mais-Valias). The rules differ for residents and non-residents.
Residents
- Only 50% of the net capital gain is added to your taxable income and taxed at progressive income tax rates (up to 48% for 2025/2026, plus a 5% solidarity surcharge on very high incomes).
- You can deduct the original purchase price (adjusted for inflation using official coefficients), documented improvement costs (within the last 12 years), and transaction costs (e.g., real estate agent fees, IMT paid on purchase).
- Primary residence rollover exemption: If you reinvest the full sale proceeds in another primary residence within Portugal or the EU/EEA within 36 months (or purchased within the preceding 24 months), the gain can be fully exempt.
Non-Residents
- EU/EEA residents: Can opt to be taxed under the same rules as Portuguese residents (50% inclusion rate at progressive rates) since a 2023 legislative change upheld through 2025/2026.
- Non-EU/EEA non-residents: The full capital gain is taxed at a flat rate of 28%, with no 50% exclusion.
Example: Resident Capital Gains
You bought an apartment in 2018 for €200,000 and sell it in 2025 for €350,000. After inflation adjustment and deductible costs totaling €30,000:
Net Gain = €350,000 – €200,000 – €30,000 = €120,000 Taxable Amount = €120,000 × 50% = €60,000 (added to your other income)
This would be taxed at your marginal income tax rate. Use our Portugal Income Tax Calculator to estimate the tax impact on your overall income.
Common Mistakes and Misconceptions
Avoiding these pitfalls can save you money and prevent problems with the Portuguese Tax Authority:
Confusing VPT with market value. IMI and AIMI are based on the tax-assessed value (VPT), which is usually much lower than the market price. However, IMT and stamp duty are applied to the higher of the purchase price or VPT.
Forgetting to register your fiscal number (NIF). Non-residents need a Portuguese NIF to buy property and pay taxes. You'll need a fiscal representative in Portugal if you're a non-EU/EEA resident.
Missing IMI payment deadlines. Late payments incur interest and penalties. Set up direct debit or calendar reminders for May, August, and November.
Not claiming available exemptions. IMI exemptions for new purchases (primary residence) and urban rehabilitation are not always applied automatically — you may need to request them.
Ignoring AIMI obligations. Property owners with multiple assets may not realize they are above the AIMI threshold, especially as VPTs are periodically reassessed upward.
Overlooking double taxation treaties. If you're a non-resident, Portugal has extensive double taxation agreements with over 70 countries. These treaties can affect how your property income and capital gains are taxed in both Portugal and your home country. Always check the relevant treaty provisions.
Assuming the NHR regime covers property taxes. The original NHR regime (and its 2024 successor) primarily affected income tax. IMI, IMT, stamp duty, and AIMI apply equally to NHR beneficiaries.
Frequently Asked Questions
Do non-residents pay a higher property tax rate in Portugal?
No. IMI rates are the same for residents and non-residents. The rate depends on the municipality and the property type, not the owner's residency status. However, non-residents face different capital gains tax rules when selling.
Can I get an IMI exemption for my first property?
Yes. If you purchase a property for permanent residence and the VPT does not exceed €125,000, you may be exempt from IMI for three years from the date of purchase. This exemption must typically be requested within 60 days of acquisition. Your household income must also be below a specified threshold (generally around €153,300 of total taxable income).
Is rental income from Portuguese property taxed separately?
Yes. Rental income from property in Portugal is subject to income tax. Residents include it in their annual tax return at progressive rates (or may opt for the flat 28%/25% rate depending on circumstances). Non-residents are taxed at a flat rate of 25% on gross rental income (2025/2026), unless a double taxation treaty provides for a different treatment.
When is AIMI due?
AIMI is assessed and payable in June each year, based on property ownership as of January 1.
Do I need to file a tax return just for owning property?
Residents include property-related income (e.g., rent) in their annual IRS return. Non-residents who only own property and receive no income from it generally do not need to file an income tax return — IMI is assessed and collected separately. However, non-residents receiving rental income must file a Portuguese tax return.
