Setting up a company is a common next step for people who have relocated to Portugal — whether to run a consultancy, hold property, invoice international clients or build a local business. The process is well established and open to foreign nationals, but the choices you make at the start affect your liability, your tax position and the insurance you are obliged to hold. This guide walks through choosing a legal form (with a focus on the single-member limited company), the two main routes to incorporation, the accounting obligations that follow, the insurance that is mandatory, and the start-up costs to plan for. It complements the tax-registration steps in our relocation services, since a company cannot be formed without each participant holding a NIF.

Choosing the legal form

The right structure depends on how many owners there are, how much personal protection you want and how you intend to be taxed. For most individual entrepreneurs relocating to Portugal, the decision comes down to three options.

Sole trader, Unipessoal Lda and Lda

The Unipessoal Lda is popular precisely because it combines limited liability with a manageable structure. It gives a professional footing for contracts and invoicing while ring-fencing personal assets, without the greater complexity of a public limited company (S.A.). If you expect to bring in partners or investors later, it is worth discussing the structure with an accountant at the outset so the initial choice does not become an obstacle.

Empresa na Hora versus the traditional route

There are two established ways to incorporate.

Empresa na Hora ("company in an hour")

This fast-track service lets you form a company in a single appointment at a dedicated desk, choosing from a list of pre-approved company names and standard, off-the-shelf articles of association. It is quick and convenient, and well suited to a straightforward Unipessoal Lda where the standard model fits your needs.

The traditional route

The traditional process — reserving a bespoke company name and drafting tailored articles before registering — takes longer but offers more flexibility. It is the better choice where you need specific clauses, an unusual shareholding arrangement or a particular company name that is not available off the shelf. Many foreign founders use the traditional route when the structure is anything other than standard, and rely on professional support to prepare the documents correctly.

Whichever route you choose, expect to need each participant's NIF, identification, a registered company address and a decision on the business activity codes (CAE) that describe what the company does.

Accounting and reporting obligations

A Portuguese limited company carries ongoing obligations that begin as soon as it is incorporated. In practice, a company is required to keep organised accounts and to work with a Certified Accountant (Contabilista Certificado), who is responsible for the regulated bookkeeping and filings. Typical duties include:

Because these obligations are continuous, budgeting for monthly accounting is part of the real cost of running a company, not an optional extra. The technical work must be carried out by a qualified professional; a broker or concierge coordinates the setup but does not perform reserved accounting acts.

Mandatory insurance for your company

Insurance is where many new company owners underestimate their obligations. Two areas matter most:

Workplace accident insurance (acidentes de trabalho)

If your company has employees — and, in many cases, for the working directors themselves — workplace accident insurance is compulsory in Portugal. It covers work-related injury and is one of the first policies a new employer must arrange. This is a legal requirement rather than a discretionary cover, and operating without it exposes the company to serious consequences. We explain employer obligations in more detail in our guide to mandatory insurance for companies in Portugal.

Professional indemnity / professional civil liability

For many regulated professions and advisory activities, professional indemnity insurance (responsabilidade civil profissional) is either required by law or by the professional body, and is strongly advisable even where it is not strictly mandatory. It responds to claims arising from professional errors or negligence. Whether it is compulsory depends on your specific activity, so confirm the position for your sector — our article on professional indemnity insurance explains how it works and who typically needs it.

Beyond these, depending on your premises and activity you may also want general public liability and property cover. The obligations vary by sector, so it is worth having your specific activity reviewed rather than assuming a standard package fits.

Start-up costs to plan for

The cost of getting a company up and running is a combination of one-off and recurring items. Rather than quote figures that quickly date, it is more useful to know what to budget for:

Because these amounts change and depend on your circumstances, we deliberately avoid publishing specific numbers here; ask for a current, itemised estimate before you commit so there are no surprises after formation.
