Opening a company in Portugal as a Brazilian: single-member or partnership?

Brazilian citizens can set up companies in Portugal, whether or not they live there. The process is quick and can be done within a few days, but choosing the legal form and the tax framework is strategic: some decisions made at incorporation are hard to change later.

This guide compares the most common forms, walks through the steps to open the company and summarises the obligations that begin the next day.

What do you need before opening the company?

• NIF: the tax identification number is mandatory for shareholders and managers and can be obtained remotely through a representative.
• Tax representation: non-residents may need to appoint a tax representative, except where the law allows opting for electronic notifications instead.
• Registered address: the company needs a registered office in Portugal, which can be an office, a domiciliation address or the home of a resident shareholder.
• Company name: it can be chosen from a pre-approved list or requested through a name admissibility certificate.

Single-member company, private limited company or sole trader?

The single-member private company is the most common choice for solo founders who want to separate personal and business assets. The private limited company with two or more shareholders calls for extra care with the articles of association and a shareholders' agreement covering entry and exit, profit distribution and decision-making.

How to incorporate the company, step by step

1. Define the structure: legal form, shareholders, management, share capital and activity code (CAE).
2. Incorporate the company in person through the Empresa na Hora service, or online through the ePortugal portal. With standard articles and a pre-approved name, registration can be done the same day.
3. Declare the start of activity with the tax authority and register with social security.
4. Declare the beneficial owner in the RCBE register, generally within 30 days of incorporation.
5. Open the company bank account and pay up the share capital.
6. Hire a certified accountant, which is mandatory for companies.

What are the costs and obligations after opening?

The minimum capital is low, but real costs include registration, certified accounting, tax filings (VAT, corporate income tax, the annual accounting information return) and, depending on the activity, specific licences. The company's books and minutes must also be kept up to date.

The tax framework should be assessed before incorporation: VAT regime, corporate taxation of profits, dividend distribution and any taxation in Brazil. The Brazil–Portugal double taxation treaty helps coordinate the two systems but does not replace planning on its own. For those with several companies or significant assets, it is also worth considering whether a holding company in Portugal makes sense.

Does opening a company give you the right to live in Portugal?

Not by itself. The company can be run remotely, but anyone who wants to live in Portugal needs their own permit, such as the entrepreneur visa or another visa suited to their profile. Before deciding, compare the options, including the D7 and D8 visas, and remember that Brazilian documents such as powers of attorney and articles of association generally need a Hague apostille.

Planning the structure from the outset makes it possible to choose the right legal form for the project, prevent disputes between shareholders and avoid unnecessary tax costs between the two countries. This article is for information only and does not replace a legal consultation.
