How to start a business in Portugal — 2026

Portugal is one of Europe's more welcoming places to start a business: you can register a limited company in a single appointment, the minimum share capital is symbolic, and corporate tax is falling. This guide walks through the practical steps — getting a NIF, choosing between sole trader and a company, registering, and the taxes and social security you will actually pay. It sits inside our wider guide on how to start an online business in Europe, and pairs well with our companion piece on starting a business in Spain.

Step 1: Get a NIF (tax number)

Nothing happens in Portugal without a NIF (Número de Identificação Fiscal) — the personal tax number issued by the tax authority, the Autoridade Tributária. You need it to sign a lease, open a bank account, register a business or even a mobile contract.

• EU/EEA residents can request a NIF directly at a Finanças (tax office) or Loja do Cidadão with ID and proof of address.
• Non-EU residents generally need to appoint a fiscal representative resident in Portugal to obtain one, or use a paid service.

The NIF itself is free. A company gets a separate corporate number, the NIPC, when it registers (below).

Step 2: Sole trader (ENI) vs company (Lda)

The two routes most SMB founders weigh up:

Sole trader — Empresário em Nome Individual (ENI), a.k.a. trabalhador independente. Fast, cheap and light on admin. You register your activity at Finanças, issue invoices as recibos verdes (green receipts) through the Portal das Finanças, and are taxed under Category B of personal income tax (IRS). The catch: no separation between you and the business — your personal assets are exposed to business debts.

Private limited company — Sociedade por Quotas (Lda). A separate legal entity with limited liability. Since the 2011 reform, the minimum share capital is €1 per shareholder — €1 for a single-owner Sociedade Unipessoal por Quotas, or €2 for a two-partner Lda. That makes an Lda genuinely accessible, and it is the standard choice once you have real revenue, employees, or partners. Sources: LVP Advogados; gov.pt (sociedade por quotas).

If you are building an online business or a services firm expecting to grow, the Lda is usually worth the modest extra cost and accountant fees.

Step 3: Register the company — Empresa na Hora

Portugal's flagship shortcut is Empresa na Hora ("company on the spot"). You attend a dedicated counter with the required documents and walk out the same day with a registered company, its NIPC, social security registration and a company name from an approved list. It works for limited companies, single-member companies and joint-stock companies.

• Cost: around €360 in public fees for the standard incorporation.
• Timing: the certificate is issued on the spot; allow 1–3 business days for the company to become fully active.
• Alternative: Empresa Online lets you incorporate through the gov.pt portal with a digital certificate if you prefer not to attend in person.

If you want a custom company name rather than one from the pre-approved list, request a certificate of admissibility (Certificado de Admissibilidade) from the RNPC first. Sources: gov.pt (Empresa Online); InvoiceXpress.

Step 4: Social security

Once you are active, social security (Segurança Social) contributions apply.

• Self-employed (ENI): the standard contribution rate is 21.4%, but it is charged on a reduced base — 70% of your relevant income for service providers — so the effective rate on gross turnover is roughly 15%. Crucially, new self-employed workers get a 12-month exemption from contributions when they first register.
• Company directors and employees: the combined rate is 34.75% (23.75% employer + 11% employee) on salaries.

Step 5: VAT (IVA)

Portuguese VAT is IVA, with a standard rate of 23% on the mainland (lower rates apply in Madeira and the Azores).

• Small-turnover exemption: under Article 53 of the VAT Code, businesses with annual turnover below €15,000 are exempt from charging IVA. Cross the threshold and you must register and start charging in the following month.
• Once registered, you file periodic IVA returns and can reclaim input VAT.

Selling to customers in other EU countries changes how VAT applies — our EU VAT calculator is a quick way to work out what to charge on cross-border invoices.

Step 6: Corporate income tax (IRC)

Companies pay IRC (Imposto sobre o Rendimento das Pessoas Coletivas). Portugal is in the middle of a staged rate cut:

• Standard IRC rate: 19% for financial years beginning on or after 1 January 2026 (down from 21% previously, with further reductions to 18% and 17% planned in coming years).
• SME reduced rate: 15% on the first €50,000 of taxable income (10.5% in Madeira and the Azores).
• Municipal surcharge (derrama municipal): up to 1.5% of taxable profit, set locally.
• State surcharge (derrama estadual): 3% / 5% / 9% on profits above €1.5m / €7.5m / €35m — so it only affects larger companies.

What it costs, roughly

• NIF: free (fiscal representative fees may apply for non-residents).
• Sole trader registration: free at Finanças.
• Lda via Empresa na Hora: ~€360 public fees, plus €1–€2 minimum capital.
• Ongoing: a certified accountant (contabilista certificado) is effectively mandatory for a company — budget from roughly €100–€200+ per month depending on activity.

Quick checklist

1. Get your NIF (appoint a fiscal representative if non-EU).
2. Decide ENI (fast, personal liability) vs Lda (limited liability, €1 capital).
3. Register — Empresa na Hora for a same-day Lda, or Finanças for a sole trader.
4. Confirm social security registration; remember the 12-month self-employed exemption.
5. Track turnover against the €15,000 IVA threshold.
6. Engage a certified accountant and plan for IRC at 19% / 15% SME.
