Portugal is a country of small and medium companies, most of them built in the last three or four decades by founders who are now in their sixties and seventies. KPMG's work on Portuguese family firms puts their average age at sixty-seven years, with 31% already run by a second-generation chief executive. A great many of the rest will change hands in the coming decade, and a large share of those will go to buyers outside the family.
Selling here is procedurally lighter than in most of Europe — a quota transfer needs no notary at all — but it carries three specifically Portuguese things that decide the outcome: a property transfer tax that can be triggered by buying shares, an employee who can legally refuse to move with the business, and a tax rule that halves the seller's bill if the company holds the right certificate on the day of the sale.
This article sets out the mechanics of a Portuguese sale, what buyers diligence, and what to fix in the twelve months before you go to market.
Most owner-run Portuguese companies are a sociedade por quotas, the Lda. Since the 2006 reform, transferring its quotas requires nothing more than a written document. There is no notarial deed, no public form, no witnessed signing.
Two things follow that matter more than the form itself. First, under article 228 of the Companies Code the transfer only becomes effective towards the company once it has been notified to the company in writing or recognised by it. Second, unless the articles of association say otherwise, the transfer requires the company's consent, except where the quota moves between spouses, between ascendants and descendants, or between existing shareholders. An outside buyer falls into none of those exceptions, so consent is a condition of a normal third-party sale, not an afterthought.
The transfer is then registered at the Commercial Registry. The registry certificate is where a buyer will start, and where a messy history shows up: quotas divided among heirs decades ago and never regularised, an old partner who was paid out but never formally removed, a pledge nobody cancelled.
Read the articles before you approach anyone. Portuguese articles frequently add pre-emption rights for the other shareholders or conditions on who may hold a quota. For a sole shareholder this is background. For a company with a retired partner, a family branch or a manager holding a few per cent, it decides whether you can deliver a hundred per cent — and an outside buyer almost always wants it.
This is the point most Portuguese owners discover too late, and it has no equivalent in most other European sales.
Under article 2 of the IMT Code, buying quotas in a sociedade por quotas that owns real property is treated as a transfer of that property for property transfer tax purposes when, as a result, one shareholder comes to hold at least 75% of the share capital. A buyer acquiring your whole company is, by definition, above that line. If the company owns its factory, its warehouse or its offices, IMT becomes payable on the property, at rates that on commercial property are meaningful money.
The rule applies to the sociedade por quotas and to partnership forms, but not in the same way to a sociedade anónima, which is one of the few genuinely tax-driven reasons Portuguese companies with substantial property convert form before a sale. That conversion takes time and has to be done for real corporate reasons, not as a manoeuvre in the final month.
The alternative is to separate the property from the business before you go to market, so that the operating company is sold and the real estate stays with the family under a lease. That decision changes the price, the tax, and the buyer's financing, and it is the single structural question worth settling first. In the experience of Conclave Partners, more Portuguese deals are repriced by this one article of the tax code than by anything found in the accounts.
In a quota sale the employer does not change and employment contracts simply continue. Where a business or establishment is transferred, article 285 of the Labour Code applies: the employer's position passes to the acquirer with the contracts intact, and the seller remains jointly liable for two years after the transfer for employee credits accrued up to that date, together with the corresponding social security charges. Two years is a long tail, and buyers price it.
Article 286 adds a process. Information must be given in writing before the transfer and at least ten working days before the consultation that follows, and both seller and buyer must consult the workers' representatives with a view to reaching agreement on the measures they intend to apply. Where the affected employees have no representatives, they may appoint a committee of up to three or five members among themselves within five working days of receiving the information.
Then there is article 286-A, which is unusual in Europe. An individual employee may oppose the transfer of their contract where it could cause them serious harm — the examples given in the law are a buyer of manifestly weak solvency or in a difficult financial position, and a buyer whose work organisation policy does not merit confidence. A valid objection blocks the transfer of that contract and the employee stays with the seller. For a buyer acquiring a business for its team, that is a real risk, and it is one reason why deals involving key people are often structured as quota sales rather than asset sales.
Whatever the structure, expect a careful employment review: accruals, social security contributions, the applicable collective agreement, use of fixed-term contracts and of independent contractors, and any pending claims. Conclave Partners establishes the employment position before a process starts, because in Portugal the choice between selling the company and selling the business is decided as much by the workforce as by tax.
For an individual seller, gains on quotas and shares are taxed at a flat 28%. Aggregation with your other income is only mandatory where the assets were held for less than 365 days and your taxable income including the gain reaches the top bracket, which starts at €86,634 — a combination that almost never catches a founder selling a company built over decades.
The rule worth knowing is article 43 of the personal income tax code. Where the quotas or shares are in a micro or small company that is not listed, only 50% of the gain is taxable. Applied to the 28% rate, that is an effective 14%, and on a seven-figure gain the difference is transformative.
Micro and small are defined by the annex to Decree-Law 372/2007, on headcount, turnover and balance sheet total. An IAPMEI certification that is valid on the date of the sale is treated as sufficient proof. The certification is free, obtained online, and needs to be current — exactly the sort of administrative detail that gets forgotten in the year a company is preparing for sale, and it cannot be fixed retrospectively once the deed is signed. Check it, renew it, and keep it valid through completion.
If the quotas are held by a Portuguese company rather than by you personally, the participation exemption in article 51-C of the corporate tax code can exempt the gain at company level, broadly where the holding has been at least 10% for an uninterrupted twelve months and the other conditions of article 51 are met. The proceeds then sit in the holding company. Which route is better depends on what you intend to do with the money, and restructuring shortly before a sale attracts scrutiny.
For completeness on the buyer's side: the general corporate tax rate fell to 19% for 2026 and is legislated to fall to 18% in 2027 and 17% in 2028, with SMEs and small mid caps paying 15% on the first €50,000 of taxable income. A buyer's model runs on those numbers.
Portugal's foreign investment screening regime, Decree-Law 138/2014, is narrow. It covers strategic assets in national defence and security and in the supply of essential services in energy, transport and communications, and it allows the government to oppose the acquisition of control by a buyer from outside the EU and the EEA within thirty days of the transaction. It has rarely been applied. That is changing: the new EU screening Regulation was published on 26 June 2026, with some provisions applying from 16 July 2026 and full application from 17 January 2028, and Portugal must widen its regime to comply. Owners in sensitive sectors planning a sale to a non-EU buyer in 2027 or later should assume the rules will be broader than today's.
Merger control is the more likely constraint, and Portuguese thresholds are unusual because two of the three are based on market share rather than size. Notification to the competition authority is required where the parties reach a 50% share of a national market; or a share between 30% and 50% where at least two of them each turn over more than €5 million in Portugal; or a combined Portuguese turnover of €100 million or more where at least two of them each turn over more than €5 million. A modest company with a strong position in a narrow national market can therefore need clearance where a much larger company in a broad market would not. The authority notified a record ninety-nine operations in 2025 and has been arguing publicly for a call-in power over deals below the thresholds.
Beyond the financial review, expect concentrated attention in a few places.
Real estate and IMT, for the reasons above, including whether the property is in the company, who owns the company that owns it, and what the lease looks like if it stays out.
Employment and social security, including the two-year joint liability tail, contribution regularity, correct application of the collective agreement, and the classification of long-standing independent contractors.
Tax. Buyers look at the open assessment years, any inspection or dispute in progress, and related-party dealings. Open years are covered by a specific tax indemnity, and the size of the retention reflects how many there are.
Owner dependence and related parties. In a market of founder-run companies, buyers check carefully whether customers, suppliers and banks deal with the business or with its owner, and look at transactions with family members and connected companies. The most expensive finding in a Portuguese diligence is rarely a hidden liability; it is a web of informal arrangements that were never documented, which the buyer then prices cautiously.
Spanish and other Iberian strategic buyers are the most frequent acquirers of mid-sized Portuguese businesses, and they move fastest because the market, the language and the regulatory framework are familiar.
Private equity is active in the Portuguese lower mid-market, often with platform strategies that consolidate several companies in one sector. It pays for a team that stays after the founder leaves.
International strategic buyers pay for export positions, manufacturing capacity, brands and access to Portuguese-speaking markets, and are the ones most likely to encounter the foreign investment regime as it widens.
Management buy-outs and family succession remain common at the smaller end and are usually the most constrained by financing.
Which of them will value a particular company highest depends on what is actually being sold — a client base, a production capability, a brand, a team or a location. Sellers who ask Conclave Partners where to begin in Portugal are pointed at two things before anything else: whether the real estate is inside the company, and whether the IAPMEI certification is valid.
Expect a letter of intent with exclusivity, then diligence, then a quota purchase agreement, with the transfer document signed at completion, notified to the company and registered.
Expect warranties concentrated on tax, employment, property and licences, with specific indemnities for whatever diligence found, and a retention or escrow securing them. Warranty and indemnity insurance is increasingly used in the Portuguese mid-market but excludes what is already known.
Expect an earn-out or vendor loan where the business depends on the owner, and a transitional role for the seller.
Expect a non-compete. In a sale of a going concern the seller's duty not to compete is recognised in Portuguese law; in a quota sale it is negotiated in the contract, and its scope and duration are among the terms buyers argue hardest over.
Decide whether the real estate stays in the company or comes out, and model the IMT consequence either way.
Confirm your IAPMEI certification is valid and will remain valid through completion, and check the company still meets the micro or small thresholds.
Read the articles of association and any shareholders' agreement, and establish exactly what consent and pre-emption rules apply.
Check the Commercial Registry history and regularise anything that was never properly filed — inherited quotas, old transfers, uncancelled pledges.
Model the tax outcome with an adviser, including whether the gain belongs in your hands or in a holding company.
Review employment: accruals, contributions, collective agreement application, and the status of anyone working as an independent contractor who looks like an employee.
Assess whether your market share could bring the deal within merger control, given the 30% and 50% tests.
Document and tidy related-party arrangements.
Build a second line of management and move key relationships off yourself.
A prepared Portuguese company typically takes six to nine months from launch to completion, longer where merger control, foreign investment screening or a complicated shareholder register is involved.
Confidentiality needs care. Portuguese business communities are small and closely connected, and banks, accountants and suppliers often hear first. A staged disclosure plan and a controlled buyer list are worth more than a broad approach.
Timing matters commercially. August empties out, and a process whose most delicate moment falls in high summer loses weeks it does not recover. In our experience at Conclave Partners, a launch timed so that offers arrive in the autumn, with the property question already settled and the certification in hand, regularly saves a full quarter against one that starts in late spring.
No. Since 2006 a written document is enough. But under article 228 of the Companies Code the transfer is only effective towards the company once notified to it in writing or recognised by it, and unless the articles provide otherwise the company's consent is required for a sale to an outside buyer. The transfer is then registered at the Commercial Registry.
If your company owns real estate and the buyer ends up holding at least 75% of the share capital of a sociedade por quotas, yes — IMT is due as if the property itself had been transferred. This is the main reason to decide early whether the real estate should be separated from the operating company, or whether a change of corporate form makes sense.
In a quota sale, nothing changes legally. In a sale of the business, article 285 of the Labour Code transfers the contracts to the buyer and leaves you jointly liable for two years for employee credits accrued up to the transfer. Employees must be informed in writing and consulted, and under article 286-A an individual employee can object to the transfer where it would cause them serious harm.
An individual pays 28% on the gain. If the company is a micro or small enterprise that is not listed, only half the gain is taxable, giving an effective 14% — and a valid IAPMEI certification on the date of sale is treated as sufficient proof. If a company holds your quotas, the participation exemption may apply instead, broadly on a 10% holding held for twelve months.
Possibly, even if the company is small. Portugal requires notification not only above €100 million of combined domestic turnover, but also where the parties reach a 50% share of a national market, or a 30% to 50% share where at least two of them each turn over more than €5 million in Portugal. A strong position in a narrow market can therefore trigger it.
Six to nine months from launch to completion for a prepared business, longer with merger control, foreign investment screening or registry complications. The preparation that determines the price — the property decision, the certification, the registry history, the employment review, related-party tidying and a second line of management — takes about twelve months before that.
