From Switzerland · Remote preparation, on-site signing
Set up your company in Portugalfrom Switzerland
You are a Swiss resident considering a company in Portugal? Preparation is done remotely, in French — starting with the NIF — then you come to Lisbon to sign the articles and open the bank account in person. But the decisive issue is not Portuguese: it is your situation in Switzerland (residence, place of effective management, double taxation) that determines whether the operation is sound or risky. Here are the markers, dated 2026, to validate with a tax adviser.

The real risk is not in Portugal, it is in Switzerland
If you remain a Swiss tax resident, setting up a company in Portugal does not take you out of the Swiss tax net. Switzerland does not apply a CFC-type regime (transparency taxation of controlled foreign companies) comparable to that of neighbouring countries — a point that nonetheless remains to be confirmed for your situation.
The real risk lies elsewhere: the place of effective management. A Portuguese company genuinely administered and run from Switzerland may be regarded as having its place of effective management there and, on that basis, become subject to unlimited taxation in Switzerland (Federal Act on Direct Federal Taxation, LIFD). This is the most decisive point for a Swiss resident.
- No classic CFC regime in Switzerland [medium confidence]: it is therefore not the main angle, but it dispenses with no analysis.
- Place of effective management [high confidence]: a Portuguese company run from Switzerland may be subject to unlimited taxation there (LIFD). This is the dominant risk to anticipate.
- The only sound way to come under Portuguese taxation is to genuinely move your management, residence and activity there, with real substance.
- No address or shell replaces a real presence: it is the economic reality and the place where decisions are taken that are examined.
The Swiss markers
Residence and specificity, in brief
Swiss tax-residence test
You are a Swiss tax resident if you have your domicile or a durable stay there (LIFD) — in which case you are in principle subject to unlimited taxation in Switzerland on your income.
Specificity: place of effective management
The decisive test for a company. A Portuguese company genuinely run from Switzerland may be found to have its place of effective management there and become subject to unlimited taxation (LIFD). This is the point to frame upfront.
Swiss lump-sum taxation
Expenditure-based taxation (« forfait fiscal », lump-sum taxation) is a specific regime that may change the analysis depending on the canton and the profile. A special case: to be validated with a tax adviser.

Your process
Prepare from Switzerland, sign on site
From Switzerland, preparation is done remotely, in French — only the NIF is a fully remote step. Signing the articles and opening the bank account then take place in person, during a visit to Lisbon. We coordinate the whole process from Portugal; the exact terms (banking in particular) depend on your profile and your status as a resident of a State outside the European Union.
Obtain the NIF (remotely)
The NIF (individual Portuguese tax number) is the only fully remote step, with no travel. As a non-EU resident, appointing a tax representative is generally required. Not to be confused with the NIPC, the future company's tax number.
Frame the structure by video
Choice between ENI, Unipessoal Lda or Lda (capital from €1 per partner) and consistency with your Swiss situation, in particular the place of effective management, during a call in French. Everything is prepared upfront so your visit stays short.
Sign the articles on site
Signing the articles takes place in person in Portugal, during a visit to Lisbon. The NIPC is allocated and the Certidão Permanente (registration extract) follows; the RCBE is then declared by the partner lawyer, generally 24 to 48 hours after incorporation. Segurança Social is handled in the same wave.
Open the bank account on site
The business account is opened in person, in branch, during that same visit. Accounting is then handled by a partner Contabilista Certificado.

Frequently asked questions
Swiss resident: what people ask me
- Can I set up a company in Portugal while remaining a Swiss resident?
- Yes, it is possible. Preparation is done remotely (the NIF, in particular), but signing the articles and opening the bank account take place in person, during a visit to Lisbon. Above all, as long as you remain a Swiss tax resident, you stay liable to tax in Switzerland: if the Portuguese company is genuinely run from Switzerland, its place of effective management may be recognised there and make it subject to unlimited taxation in Switzerland (LIFD). The operation is only sound if framed upfront with a tax adviser.
- Does Switzerland have a CFC regime that would tax my Portuguese company?
- Switzerland does not apply a classic CFC-type regime comparable to that of some neighbouring countries (a point that remains to be confirmed for your situation). The dominant risk for a Swiss resident is therefore not transparency taxation, but the recognition of the company's place of effective management in Switzerland if it is genuinely run there. To be validated with a tax adviser.
- Does the Switzerland-Portugal treaty avoid double taxation?
- Yes, that is its purpose: a double-taxation treaty binds Switzerland and Portugal (commonly dated 1974, exact date to be confirmed). It allocates taxing rights and prevents double taxation, but it does not neutralise the risk that the company is attached to Switzerland if it is genuinely run there.
- I benefit from lump-sum taxation: does that change the analysis?
- Potentially, yes. Expenditure-based (lump-sum) taxation is a specific regime whose effects depend on the canton and your profile; it may change how it interacts with a Portuguese company. This is a special case that must imperatively be validated with a tax adviser before any decision.
