What Is Stamp Duty (Imposto de Selo)?
Imposto de Selo (IS) is Portugal's oldest tax, dating back to 1660. Despite its age, it remains highly relevant in 2026 because it applies to virtually every major financial transaction: property purchases, mortgages, leases, donations, and inheritances.
Unlike IMT (transfer tax), which only applies to property purchases, Stamp Duty touches the entire property lifecycle. Many buyers are surprised to find it on their closing statement — often after they thought they had budgeted for all costs.
Stamp Duty on Property Purchase (0.8%)
When you buy a property in Portugal, you pay Stamp Duty at 0.8% of the purchase price or the tax value (VPT), whichever is higher.
| Scenario | Rate | Example (300,000 EUR) |
|---|---|---|
| Urban property purchase | 0.8% | 2,400 EUR |
| Rural land purchase | 0.8% | 2,400 EUR |
| Commercial property | 0.8% | 2,400 EUR |
This is paid on the same day as IMT, at the notary. There are no exemptions for first-time buyers or primary residence.
Key point: The tax base is the higher of the purchase price and the VPT. If you buy a property for 250,000 EUR but the VPT is 280,000 EUR, you pay 0.8% x 280,000 EUR = 2,240 EUR.
Stamp Duty on Mortgages
Mortgages attract Stamp Duty at 0.6% of the loan amount (for terms over 5 years). This is separate from the purchase Stamp Duty and is paid by the borrower.
If you refinance your mortgage, you pay Stamp Duty again on the new loan amount — a cost often forgotten when calculating the break-even of a refinance.
Stamp Duty on Leases
Rental contracts are subject to Stamp Duty at 10% of one month's rent. This is a one-off payment due when the lease is signed. Short-term rentals (Alojamento Local) are exempt.
Stamp Duty on Gifts and Inheritances
Gifts and inheritances between spouses, parents, children, grandparents, and grandchildren are exempt. For all others (siblings, nephews, friends), the rate is 10%.
A property worth 300,000 EUR gifted to a sibling triggers 30,000 EUR in Stamp Duty — a figure that surprises many families.
Total Buying Costs: A Complete Example
For a 350,000 EUR property financed with a 280,000 EUR mortgage (25-year term):
| Cost | Calculation | Amount |
|---|---|---|
| IMT (transfer tax) | Varies by bracket | ~9,800 EUR |
| Stamp Duty (purchase) | 0.8% x 350,000 | 2,800 EUR |
| Stamp Duty (mortgage) | 0.6% x 280,000 | 1,680 EUR |
| Notary and Land Registry | Fixed fees | ~1,200 EUR |
| Total transaction costs | ~15,480 EUR |
This represents approximately 4.4% of the purchase price — a figure that surprises many first-time buyers who budget only for the down payment.

Stamp Duty in Portugal 2026: Complete Guide
Stamp Duty (Imposto de Selo) is one of Portugal's most comprehensive taxes, applying to a wide range of transactions, contracts, and legal documents. When buying property, it is a mandatory cost that buyers must include in their budget.
What is Stamp Duty in Portugal?
Portuguese Stamp Duty is regulated by the Stamp Duty Code (CIS) and the General Stamp Duty Table (TGIS). It is an indirect tax on the transfer of assets, contracts, documents, and other legal acts.

Mortgage (home loan):
- Rate: 0.6% on the loan amount
Inheritance and gift of property:
- Rate: 10% on the property value (except spouses, children, and parents, who are exempt)
Tax Base: Acquisition Value vs. VPT
Stamp Duty applies to the higher of:
-
Declared value in the deed (purchase price)

Regional Market Analysis
The Portuguese rental market in 2026 shows significant regional variation:
Lisbon: Average rents for a T2 apartment range from €1,200-€2,500/month depending on neighbourhood. Prime areas (Chiado, Príncipe Real, Avenidas Novas) command €2,000-€3,500. The market remains tight with vacancy rates below 2% in central parishes.
Porto: T2 rents range from €800-€1,800/month. The Baixa and Foz do Douro areas are most expensive. Porto has seen the fastest rent growth in Portugal over the past 3 years, driven by tech companies and digital nomads.
Algarve: Highly seasonal. Annual contracts for T2 apartments: €700-€1,500/month. Short-term summer rentals can generate €1,500-€4,000/week in peak season, but occupancy drops to 30-40% in winter months.
Interior and smaller cities: Coimbra, Braga, Aveiro, and Évora offer T2 rents of €500-€900/month. These markets are less liquid but offer higher gross yields (5-7% vs 3-4% in Lisbon).
Legislative Framework: Novo Regime do Arrendamento
The Portuguese rental market operates under the NRAU (Novo Regime do Arrendamento Urbano), last significantly amended in 2023-2024. Key provisions affecting investors:
- Rent increases: Limited to the annual coefficient published by INE (based on inflation). For 2026, the coefficient is approximately 2-3%.
- Contract duration: Minimum 1 year for new contracts (previously could be shorter). Contracts automatically renew unless terminated with proper notice.
- Tenant protections: Eviction for personal use requires 6 months' notice and compensation in certain cases. Non-payment eviction takes 3-12 months through courts.
- Tax incentives: Reduced IRS rates for long-term contracts: 25% for 2-5 year contracts, 15% for 5-10 years, 10% for 10-20 years, 5% for 20+ years (vs standard 28% autonomous taxation).
Yield Calculation and Investment Strategy
For buy-to-let investors, understanding the difference between gross and net yield is critical:
Gross yield = Annual rent / Purchase price × 100 Net yield = (Annual rent - Annual costs) / (Purchase price + Acquisition costs) × 100
Typical annual costs for a Portuguese rental property:
- IMI (property tax): 0.3-0.45% of VPT
- Condominium fees: €30-€150/month
- Insurance: €150-€400/year
- Maintenance reserve: 5-10% of annual rent
- Management fees (if applicable): 8-12% of rent
- Vacancy allowance: 5-8% of annual rent

Short-Term vs Long-Term Rental
The decision between Alojamento Local (short-term/Airbnb) and traditional long-term rental depends on several factors:
| Factor | Short-Term (AL) | Long-Term |
|---|---|---|
| Gross income | 30-80% higher | Stable, predictable |
| Management effort | High (daily) | Low (monthly) |
| Vacancy risk | Seasonal, 20-40% | Low, 5-8% |
| Regulation risk | High (moratoriums, caps) | Lower |
| Tax rate | 35% (simplified) or 28% | 15-28% (duration-based) |
| Wear and tear | Higher | Lower |
Our Airbnb Investment Calculator and Airbnb vs Long-Term Rental tools help you model both scenarios with real occupancy and pricing data.
Âmbito do Imposto de Selo
O Imposto de Selo (IS) é um dos impostos mais antigos de Portugal, incidindo sobre uma vasta gama de actos jurídicos, contratos e operações financeiras. No contexto imobiliário, aplica-se em várias situações:
Aquisição de Imóveis
Taxa de 0.8% sobre o valor de aquisição ou o Valor Patrimonial Tributário (VPT), consoante o que for superior. Este imposto é sempre devido, sem isenções (ao contrário do IMT que tem escalões isentos para HPP).
Exemplo: Apartamento adquirido por €250,000 com VPT de €180,000 → IS = €250,000 × 0.8% = €2,000
Crédito Habitação
O IS incide sobre o montante do empréstimo bancário, com taxas que variam conforme o prazo:
- Prazo ≤ 1 ano: 0.04% por mês (ou fracção)
- Prazo > 1 ano e ≤ 5 anos: 0.5%
- Prazo > 5 anos: 0.6%
Exemplo: Crédito de €200,000 a 30 anos → IS = €200,000 × 0.6% = €1,200
Garantias (Hipoteca)
A constituição de hipoteca a favor do banco está sujeita a IS de 0.04% por mês sobre o valor garantido, com um mínimo de 0.5% e máximo de 0.6% (para prazos superiores a 5 anos).
Imposto de Selo sobre Doações e Heranças
Desde 2004, Portugal não tem imposto sobre sucessões. No entanto, o Imposto de Selo aplica-se a transmissões gratuitas (doações e heranças) de imóveis:
- Cônjuge, descendentes e ascendentes: Isentos de IS
- Outros herdeiros/donatários: Taxa de 10% sobre o VPT do imóvel
Esta isenção para familiares directos torna Portugal um dos países mais favoráveis da Europa para transmissão de património imobiliário entre gerações.
IS sobre Arrendamento
Os contratos de arrendamento estão sujeitos a IS de 10% sobre o valor da renda mensal. Este imposto é devido pelo senhorio no momento da celebração do contrato e aplica-se à totalidade da renda do primeiro período contratual.
Exemplo: Contrato de arrendamento com renda de €1,000/mês, duração de 1 ano → IS = €1,000 × 12 × 10% = €1,200 (pago de uma só vez na celebração)
Verba 28.1: Imóveis de Luxo
A Verba 28.1 da Tabela Geral do IS impõe uma taxa adicional de 1% sobre imóveis com VPT igual ou superior a €1,000,000 (para imóveis habitacionais). Este imposto é anual e adiciona-se ao IMI.
Nota: O VPT é frequentemente inferior ao valor de mercado, pelo que muitos imóveis com valor de mercado acima de €1M não são abrangidos por esta verba. Contudo, reavaliações patrimoniais podem alterar esta situação.
Optimização Fiscal
Estratégias legais para minimizar o IS no contexto imobiliário:
- Aquisição por empresa: Pode ser vantajoso em determinados cenários, mas não altera a taxa de IS sobre a aquisição
- Doação em vida vs herança: Para familiares directos, ambas são isentas. Para outros, planear a transmissão pode evitar a taxa de 10%
- Fraccionamento: Dividir uma aquisição em terreno + construção (contratos separados) pode reduzir a base tributável do IS em alguns casos
