Key Legal Rules for Buying and Selling Property
Property transactions in Portugal follow a clear legal framework that ensures protection and transparency for both buyers and sellers. Below is a practical overview of the most important rules that apply.
Legal Essentials You Should Know Before Signing
Promissory Contract, Deposit, and Breach
Most transactions begin with a promissory sale contract (Contrato-Promessa de Compra e Venda, or CPCV). This agreement secures the terms of the deal before the final deed is signed. A deposit, usually between 10% and 20% of the sale price, is paid at this stage.
The standard period between signing the CPCV and completing the deed is around 60 days. If the buyer fails to proceed, the seller may retain the deposit. If the seller defaults, the buyer may claim double the deposit as compensation.
Sale vs Construction Contract
It’s crucial to distinguish between a sale contract and a construction (empreitada) contract. A typical sale contract involves the transfer of an existing or pre-approved property.
In contrast, an empreitada governs the construction of a property and often implies higher technical responsibilities and post-completion liabilities for the builder. This difference can affect tax obligations, guarantees, and how the transaction is legally structured.
Contract Form Requirements
Under Portuguese law, a sale contract must be executed either by public deed before a notary or by an authenticated private document before a lawyer or solicitor. Without this formality, the contract is not legally valid.
Registration and Effectiveness Against Third Parties
Even after signing the deed, the buyer’s ownership is not fully enforceable against third parties until the transaction is registered with the Land Registry. This step confirms legal title and protects the buyer’s rights in any future disputes.
Pre-emption Rights
Certain parties may have the right of first refusal in a property sale. These can include tenants, co-owners, or public entities such as municipalities, especially when the property is in a designated rehabilitation area. Sellers must notify these parties and provide proof that such rights have been respected before the deed can be signed.
Mortgage Financing
Banks in Portugal typically finance up to 90% of the property value for primary residences and 80% for secondary homes. Buyers must meet a debt-to-income ratio, generally capped at 30%, meaning that monthly loan payments should not exceed 30% of the borrower’s net income. Mortgage deeds are often signed at the same time as the purchase deed, and the mortgage is registered as a lien on the property.
Anti-Money Laundering Compliance
All real estate transactions are subject to anti-money laundering controls. Buyers and sellers must identify the bank accounts used for payments. Cash transactions over €3,000 (or €10,000 for non-residents) are prohibited. Lawyers and notaries are required to conduct due diligence and report suspicious transactions to the authorities.
Construction Warranties for New Properties
When buying a newly built property, buyers are protected even if they did not directly contract the builder. Portuguese law provides a five-year warranty for structural defects and general protections for other faults under the Civil Code. Any issues must be reported in writing within one year of being detected.
Essential Property Documents
What You’ll Need to Validate the Purchase or Sale
To legally complete a property transaction in Portugal, both buyers and sellers must gather a standard set of documents. These ensure the property is properly registered, free of legal issues, and compliant with building and tax regulations.
Land Registry Certificate (Certidão do Registo Predial)
Confirms legal ownership and discloses any mortgages or encumbrances.
Tax Certificate (Caderneta Predial Urbana)
Identifies the property for tax purposes and shows its fiscal valuation.
Usage License (Licença de Utilização)
Required for residential buildings constructed after 1951 to confirm legal habitation status.
Energy Performance Certificate (Certificado Energético)
Mandatory prior to sale or advertising, this rates the property’s energy efficiency.
Housing Technical File (Ficha Técnica da Habitação)
Required for properties licensed after 30 March 2004, detailing construction specifications.
Condominium Debt Statement
For properties in shared buildings, this confirms there are no outstanding dues. It may be waived only if the buyer explicitly accepts the risk.
Identification Documents
Valid passport or citizen card, plus Portuguese tax number (NIF), are required from all parties.
Declaration of Estate Agent Involvement
The deed must state whether a licensed real estate agent participated, including their license number and commission terms, if applicable.

Key Tax Rules for Buying and Selling Property
What You Need to Know Before You Close the Deal
Whether you’re purchasing your future home or selling an investment, understanding the tax implications of real estate transactions in Portugal is essential — and can help you avoid costly surprises.
For Buyers
IMT (Property Transfer Tax)
IMT is a one-time tax paid before signing the final deed. It is calculated on the higher of the purchase price or the property’s official tax value (VPT). For primary residences, rates start at 0% and rise progressively up to 7.5%.
Since August 2024, buyers under the age of 35 purchasing their first permanent home may benefit from a significant tax relief.
- Properties valued up to €324,058 are fully exempt from IMT.
- For homes priced between €324,058 and €648,022, a partial exemption applies — tax is due only on the portion exceeding the threshold.
- Properties above €648,022 do not benefit from this regime.
- These exemptions are automatic and not dependent on income.
Stamp Duty
Stamp duty is charged at a flat rate of 0.8%, also based on the higher of the purchase price or the VPT. Buyers under 35 who qualify for IMT relief are equally entitled to full or partial exemption from stamp duty, under the same property value thresholds.
IMI (Annual Municipal Property Tax)
Once the purchase is completed, the new owner becomes responsible for IMI, an annual tax charged on the property’s official tax value. Rates range from 0.3% to 0.45%, depending on the municipality. IMI is typically payable in May, with the option to split the amount into installments if the annual bill exceeds €100.
AIMI (Additional Property Tax)
AIMI applies to high-value residential property holdings — specifically when the total VPT exceeds €600,000 per person. The applicable rate is 0.7%, increasing to 1% or 1.5% for larger holdings or for properties owned by companies.
For Sellers
Capital Gains Tax
When you sell a property for more than you originally paid, the profit — or capital gain — is subject to tax in Portugal.
This gain is calculated as the difference between the sale price and the original purchase price, adjusted for inflation and reduced by eligible expenses.
For Companies
IRC
If the seller is a company, 100% of the capital gain is taxed as part of the business’s taxable profit under the corporate income tax regime (IRC).
Some relief may apply if the gain is reinvested in qualifying business assets, allowing for partial deferral of the tax under specific conditions.
For Individuals
IRS
If you’re a private seller (not a company), 50% of your capital gain is added to your annual income and taxed under the progressive IRS rates, which range from 14.5% to 48%.
However, if the property was used for short-term rentals (Alojamento Local) in the previous 3 years, the gain is fully taxable — the 50% reduction does not apply.
You may deduct eligible expenses, such as property improvement works (incurred in the previous 12 years), real estate agency commissions, property taxes paid on the acquisition (IMT and Stamp Duty) and notary and registration fees, provided they are properly documented.
Reinvestment Exemption
Sellers may benefit from partial or full exemption if the property sold was their primary residence and the proceeds are reinvested in another primary home.
To qualify, the new home must be purchased within 36 months after or 24 months before the sale.
Additionally, the property sold must have been used as the seller’s primary residence for at least 12 months prior to the sale. This rule applies to reinvestments within Portugal or other EU/EEA countries, as long as the taxpayer is tax resident in Portugal.
For Non-Residents
As of 2023, non-residents are also taxed under progressive IRS rates (on 50% of the gain) — they no longer benefit from the former flat 28% regime. In determining the tax rate, the Portuguese tax authorities will consider the seller’s worldwide income (employment and/or pension income).

What to Expect
From First Question to Final Signature
Buying or selling property in Portugal shouldn’t feel overwhelming. At Step Inside Legal, we guide you through each stage of the process — with legal clarity, tax insight, and practical support that’s tailored to your transaction.
Initial Consultation
We start by understanding your situation — whether you're buying, selling, or both — and outline the key legal and fiscal considerations specific to your case.
Legal Due Diligence
Before any contract is signed, we review the property’s legal documentation: land registry, tax certificate, usage license, energy certificate, condominium statements, and more. If you’re selling, we verify what must be provided. If you’re buying, we flag any issues that could impact the transaction.
Drafting or Review of the Promissory Contract (CPCV)
We prepare or analyse the promissory sale contract to protect your interests, ensure compliance with Portuguese law, and anticipate practical issues such as deposit terms, penalties for breach, and deadlines for completion.
Preparation for the Deed
Between signing the CPCV and the final deed, we help collect all necessary documentation. For sellers, this includes ensuring all property documents are current and compliant. For buyers, we assist with calculating and paying taxes such as IMT and Stamp Duty — on time and with certified proof — to ensure everything is ready for the notary.
Signing the Final Deed
We accompany you to the notary (or represent you via power of attorney), verify the final terms, and ensure the deed is correctly executed and legally binding. If the transaction involves bank financing, we coordinate the signing of the mortgage and the release of funds.
Tax Consultation and Filing
We advise on the taxes that apply to your transaction — from IMT and Stamp Duty to capital gains. If you’re selling, we help calculate the taxable amount and explain any exemptions or reinvestment benefits that may apply.
Post-Sale Support
After the deed, we assist with registering the new ownership, updating utilities, liaising with the condominium (if applicable), and ensuring any final tax or administrative steps are completed.

FAQs
Frequently Asked Questions
Do I need a lawyer to buy or sell property in Portugal?
While not legally mandatory, having a lawyer is highly recommended — especially for international clients. A lawyer ensures the property is legally compliant, drafts or reviews contracts, represents your interests, and helps you navigate tax and registration procedures.
Can foreigners buy property in Portugal?
Yes. Portugal places no restrictions on foreign property ownership. Both EU and non-EU citizens can buy freely, and the legal process is the same for residents and non-residents.
What are the main taxes I need to pay when buying a property?
Buyers must pay IMT (property transfer tax), stamp duty (0.8%), and will become responsible for annual IMI (municipal tax). AIMI may apply to high-value properties. First-time buyers under 35 may qualify for IMT and stamp duty exemptions.
How is capital gains tax calculated when I sell?
The gain is the difference between the sale price and the adjusted purchase price (considering inflation and deductible expenses). Individuals are taxed on 50% of the gain, except in short-term rental cases. Reinvestment in a new primary residence may offer full or partial exemption.
Is a promissory contract (CPCV) necessary?
Not legally required, but strongly recommended. It binds both parties and usually includes a deposit. It can also include clauses for specific performance or penalties in case of breach.
How long does the buying process usually take?
On average, the full process — from signing the promissory contract to the final deed — takes 30 to 60 days, depending on due diligence, financing, and document readiness.
What is the role of the notary in the transaction?
The notary or certifying lawyer ensures the deed is signed correctly, verifies all documentation, confirms tax payments, and registers the transaction with the authorities.
Can Step Inside Legal represent me remotely?
Yes. We frequently act under power of attorney for international clients, handling the entire transaction from due diligence to deed — including tax payments, bank coordination, and registration.
Do I need a Portuguese tax number (NIF)?
Yes. Both buyers and sellers must have a Portuguese tax identification number (NIF). We can assist you in obtaining one, even remotely.
