Whether you're buying a holiday home in the Algarve, investing in Lisbon real estate, or relocating to Porto, understanding Portugal property tax rules is essential for making informed financial decisions. Portugal levies several taxes on property — from the moment you purchase it through to annual holding costs and even when you sell.
In this comprehensive guide, we break down every property tax in Portugal you need to know for the 2025/2026 tax year, including current rates, exemptions, deadlines, and practical examples to help you plan your budget accurately.
Overview of Property Taxes in Portugal
Portugal's property tax system is made up of several distinct taxes that apply at different stages of property ownership. Here's a quick overview before we dive into the details:
- IMT (Imposto Municipal sobre Transmissões Onerosas de Imóveis) — A one-time transfer tax paid when you purchase a property
- Imposto do Selo (Stamp Duty) — A one-time stamp duty also paid at the time of purchase
- IMI (Imposto Municipal sobre Imóveis) — An annual municipal property tax
- AIMI (Adicional ao Imposto Municipal sobre Imóveis) — An additional annual wealth-style tax on higher-value property holdings
- Capital Gains Tax — Tax on profits when you sell a property
Each of these taxes has its own rates, thresholds, and exemptions. Let's explore them one by one.
IMT: Property Transfer Tax in Portugal
The IMT (Imposto Municipal sobre Transmissões Onerosas de Imóveis) is the most significant upfront cost when buying property in Portugal. It is a progressive tax based on the purchase price or the tax-registered value (valor patrimonial tributário, or VPT) of the property — whichever is higher.
IMT Rates for 2025/2026
IMT rates differ depending on whether the property will be used as a primary residence (habitação própria e permanente) or as a secondary/investment property. They also differ between mainland Portugal and the autonomous regions of Madeira and the Azores.
IMT rates for primary residences (mainland Portugal):
| Property Value (EUR) | Marginal Rate | Deduction (EUR) |
|---|---|---|
| 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) | N/A |
| Above €1,102,920 | 7.5% (flat) | N/A |
IMT rates for secondary/investment properties (mainland Portugal):
| Property Value (EUR) | Marginal Rate | Deduction (EUR) |
|---|---|---|
| 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 – €633,453 | 8% | €12,170.00 |
| €633,453 – €1,102,920 | 6% (flat) | N/A |
| Above €1,102,920 | 7.5% (flat) | N/A |
Note: Rural land is taxed at a flat rate of 5%, and properties purchased by entities based in blacklisted jurisdictions (tax havens) face a flat rate of 10%.
IMT Calculation Example
Let's say you're buying an apartment in Lisbon for €300,000 as your primary residence:
- The applicable marginal rate is 7% (for the €190,086–€316,772 bracket)
- IMT = (€300,000 × 7%) – €10,022.42
- IMT = €21,000 – €10,022.42
- IMT = €10,977.58
If the same property were a secondary home, the IMT would be:
- IMT = (€300,000 × 7%) – €9,003.25
- IMT = €21,000 – €9,003.25
- IMT = €11,996.75
Use our Portugal Property Tax Calculator to quickly estimate your IMT and other property taxes based on your specific purchase price and circumstances.
IMT Exemptions
Several IMT exemptions and reductions exist:
- Primary residences valued at or below €101,917 are fully exempt from IMT on mainland Portugal
- Properties in urban rehabilitation areas may qualify for IMT exemptions
- Properties purchased for resale by licensed real estate traders can qualify for exemptions (subject to conditions)
- Properties acquired by credit institutions through debt recovery may qualify for temporary exemptions
Stamp Duty (Imposto do Selo) on Property
In addition to IMT, buyers must pay Imposto do Selo (Stamp Duty) at the time of purchase. This is a straightforward flat rate:
- 0.8% of the purchase price or VPT (whichever is higher)
Stamp duty also applies to mortgage loans:
- Mortgages with a term of 1–5 years: 0.6% of the loan amount
- Mortgages with a term of 5+ years: 0.6% of the loan amount
- Mortgages with no fixed term: 0.6% of the loan amount
Stamp Duty Example
For the same €300,000 Lisbon apartment:
- Property stamp duty = €300,000 × 0.8% = €2,400
- If you take out a €200,000 mortgage (term > 5 years): €200,000 × 0.6% = €1,200
- Total stamp duty = €3,600
IMI: Annual Municipal Property Tax
The IMI (Imposto Municipal sobre Imóveis) is Portugal's annual property tax, similar to council tax or property tax in other countries. It is levied by municipalities and based on the VPT (valor patrimonial tributário) — the tax-registered value of the property, which is typically lower than the market value.
IMI Rates for 2025/2026
IMI rates are set by each municipality within the following statutory ranges:
| Property Type | Rate Range |
|---|---|
| Urban properties | 0.3% – 0.45% of VPT |
| Rural properties | 0.8% of VPT |
| Properties owned by entities in tax havens | 7.5% of VPT |
Most municipalities in popular areas like Lisbon, Porto, and the Algarve apply rates between 0.3% and 0.4%. Municipalities may also apply surcharges or reductions depending on local policy.
IMI Discounts and Surcharges
Municipalities have the power to:
- Reduce IMI by up to 20% for families with dependents (reduction varies by number of dependents)
- Apply surcharges of up to 30% on properties that have been vacant for more than one year
- Offer reduced rates for properties with higher energy efficiency ratings
- Apply tripled IMI rates to properties classified as degraded (ruínas)
IMI Payment Deadlines
IMI is typically assessed based on the property ownership as of December 31 of the previous year, with payment due in the following year:
- If IMI ≤ €100: Single payment in May
- If IMI is between €100 and €500: Two installments in May and November
- If IMI > €500: Three installments in May, August, and November
IMI Exemptions
- Permanent residence exemption: Properties with a VPT of up to €125,000 used as a primary residence may be exempt from IMI for 3 years from the date of purchase or construction (subject to household income limits — typically aggregate taxable income must not exceed €153,300)
- Urban rehabilitation: Properties in designated urban rehabilitation areas that have been renovated may qualify for a 3-year IMI exemption, extendable to 5 years
- Low-income households: Households with an annual income not exceeding €16,398.17 and a total VPT of properties not exceeding €71,296.40 may qualify for exemption
IMI Calculation Example
If your Lisbon property has a VPT of €180,000 and the municipality applies a rate of 0.3%:
- IMI = €180,000 × 0.3% = €540 per year
- Paid in three installments of €180 (May, August, November)
AIMI: Additional Property Tax for High-Value Holdings
The AIMI (Adicional ao Imposto Municipal sobre Imóveis) is a supplementary tax introduced in 2017, sometimes referred to as Portugal's "wealth tax" on property. It applies to the total VPT of all urban residential properties owned by a taxpayer that exceeds a certain threshold.
AIMI Rates for 2025/2026
For individuals:
| Taxable VPT (above €600,000 exemption) | Rate |
|---|---|
| €600,001 – €1,000,000 | 0.7% |
| Above €1,000,000 | 1.0% |
For married couples filing jointly, the exemption threshold doubles to €1,200,000.
For companies:
| Entity Type | Rate |
|---|---|
| Standard companies | 0.4% (on total VPT, no exemption threshold) |
| Entities in tax havens | 7.5% |
AIMI Example
If an individual owns two residential properties with a combined VPT of €800,000:
- Exemption: €600,000
- Taxable amount: €800,000 – €600,000 = €200,000
- AIMI = €200,000 × 0.7% = €1,400 per year
AIMI is assessed in June and payable in September each year.
Capital Gains Tax on Property in Portugal
When you sell a property in Portugal at a profit, you may be liable for capital gains tax. The rules differ significantly for residents and non-residents.
For Tax Residents
- Only 50% of the capital gain is taxable
- This 50% is added to your other income and taxed at your marginal IRS (income tax) rate, which can range from 14.5% to 48%
- Rollover relief: If you reinvest the proceeds into a new primary residence in Portugal (or within the EU/EEA) within 36 months, you may be fully or partially exempt
- Primary residence exemption: Gains from selling your primary residence are exempt if the full proceeds are reinvested in another primary residence
For Non-Residents
- Capital gains are taxed at a flat rate of 28% on the full gain, OR
- Non-residents from EU/EEA countries can elect to be taxed under the same rules as residents (50% inclusion, progressive rates) if this results in a lower tax bill
- No rollover relief is generally available for non-residents (though EU/EEA residents who elect resident taxation may access it)
Allowable Deductions
When calculating capital gains, you can deduct:
- The original purchase price (adjusted for inflation if held for more than 2 years)
- IMT and stamp duty paid at purchase
- Costs of improvements made in the last 12 years (with invoices)
- Real estate agent commissions and legal fees
- Energy efficiency certification costs

Key Tips and Common Mistakes
Navigating property tax in Portugal can be complex, especially for foreign buyers. Here are the most common pitfalls and practical tips:
Common Mistakes
Confusing market value with VPT: IMI and AIMI are calculated on the VPT (tax-registered value), not the market price. The VPT is typically 20–50% lower than the purchase price, though the tax authorities can reassess it.
Forgetting about AIMI: Many property investors focus solely on IMI and overlook AIMI, which can add a significant annual cost for portfolios with high combined VPTs.
Missing the IMI exemption deadline: The 3-year IMI exemption for primary residences is not automatic — you must apply within 60 days of purchasing the property.
Not claiming all capital gains deductions: Failing to keep receipts for property improvements can cost you thousands in unnecessary capital gains tax when you sell.
Ignoring double taxation treaties: If you're a tax resident in another country, Portugal has double taxation agreements (DTAs) with over 80 countries. These can prevent you from being taxed twice on the same property income or gains. Always check the relevant DTA.
Practical Tips
- Check your municipality's IMI rate — rates vary significantly between municipalities, and this can affect your annual costs by hundreds of euros
- Request an updated caderneta predial (property tax document) before purchasing to verify the VPT
- Budget for all purchase taxes — IMT + stamp duty typically adds 6–10% to the purchase price
- Non-habitual resident (NHR) status ended for new applicants in 2024, but those already registered continue to benefit; the new IFICI regime (tax incentive for scientific research and innovation) may offer benefits for qualifying individuals from 2024 onward
- Keep all property-related invoices organized and retained for at least 12 years
