Portugal has leaned hard into digital-first registration, and it shows: a sole trader can be up and invoicing within days, and a company can be formed in about an hour at an Empresa na Hora desk. Here's what it takes to start a business in Portugal in 2026.

1. Which business structure fits you?

Before you register anything, it helps to know what you're actually choosing between.

  • Empresário em Nome Individual (ENI). A sole proprietorship, the default for freelancers, consultants, and small retailers. No minimum capital, no articles of association, and you're personally liable for whatever the business owes.
  • Sociedade Unipessoal por Quotas. A single-member limited liability company, with just €1 in minimum share capital, giving you legal separation from the business without needing a co-founder.
  • Lda (Sociedade por Quotas) or SA. Multi-member limited liability company or public limited company, the latter requiring €50,000 in minimum capital and generally reserved for larger operations.

2. Register your business

ENI (sole trader)

You don't file a formation document at all. You need an NIF (Portuguese tax number), and then you submit a Declaração de Início de Atividade (declaration of business activity) through the Portal das Finanças to formally start trading. If you're not a Portuguese national with a Citizen's Card, you'll apply for the NIF separately first, and non-EU non-residents generally need a fiscal representative.

Companies

You register through Empresa na Hora, an in-person same-day service available at designated desks across the country, or Empresa Online, the fully digital equivalent. Empresa na Hora typically costs around €360; Empresa Online can start as low as €220 if you use a pre-approved standard company template (pacto social). Either way, you'll walk away with a commercial registration certificate confirming your company's legal existence.

3. Get your NIF and NISS

Your NIF (Número de Identificação Fiscal) is the tax identification number every individual and business in Portugal needs before anything else, and it's free to obtain. You'll also need a NISS (social security identification number) to start social security contributions, whether you're a sole trader or a company owner.

4. Check licenses and permits

Portugal doesn't issue a single national business license. What you need depends on your CAE code, the economic activity classification you select at registration, and your municipality. Regulated professions need their own authorization, and certain activities carry additional local permits. Check with your local câmara municipal for anything industry-specific.

5. Understand Portuguese taxes

ENI income is taxed under personal income tax (IRS) as Category B income, with brackets running from 13% to 48%. Most sole traders under €200,000 in annual turnover use the simplified regime, which taxes a percentage of turnover rather than actual profit; for many service businesses, this works out to roughly 75% of revenue being taxable. Payments from Portuguese business clients typically carry a uniform 23% withholding at source, credited against your final IRS bill. Self-employed workers also pay social security at 21.4%, calculated on 70% of quarterly income, though the first 12 months of activity are generally exempt from contributions entirely, a genuine head start for new founders.

Companies pay corporate income tax (IRC) at 19% standard, reduced to 15% on the first €50,000 of profit for qualifying SMEs, with an even lower 12.5% rate available for SMEs headquartered in Portugal's Interior territories.

VAT (IVA) is 23% standard on the mainland (22% in Madeira, 16% in the Azores), with intermediate and reduced rates of 13% and 6% for specific categories. Registration is required once turnover exceeds €15,000 a year; below that, sole traders and small businesses can operate VAT-exempt.

6. Stay compliant

Every company must appoint a Certified Accountant (TOC) to manage tax filings, a legal requirement, not just a convenience. Corporate tax returns are due between 16 April and 16 May each year. Individual IRS returns for the prior year are filed between April and June. VAT returns are typically filed monthly or quarterly depending on turnover, with payment due about a week after the reporting deadline.
