Starting a Company in Portugal 2026: The Empresa na Hora Desk, the Sociedade por Quotas, the ENI Route, and How to Open a Business in 90 Minutes

Setting up a company in Portugal in 2026 is fast — sometimes astonishingly fast — but the speed can mask a stack of decisions that will shape your tax bill, your personal liability and your social-security bill for years. This guide walks through every step an expat needs to know to open a Portuguese company or launch as a trabalhador independente in 2026: the Empresa na Hora desk, the sociedade por quotas form, the single-shareholder unipessoal variant, the empresário em nome individual (ENI) route, the sociedade anónima, and the tax, accounting and social-security architecture that sits around them.

1. Pick the Right Legal Form

Portuguese company law recognises a handful of legal forms. For expats the practical choice is between four:

• ENI — Empresário em Nome Individual. Not a company at all; the business is the person. One NIF, no share capital, unlimited personal liability. Taxed under IRS Category B. This is the cheapest, fastest route — a simple Finanças declaration — but exposes your personal assets.
• Sociedade Unipessoal por Quotas. Single-shareholder private limited company. Separate legal personality, liability ring-fenced at the company, minimum share capital €1 (yes, one euro), taxed under IRC. The most common form for expat-founded Portuguese micro-businesses.
• Sociedade por Quotas (LDA). Two or more shareholders. Same mechanics as the unipessoal but with multiple partners, a partnership deed (pacto social), and the formal quota-based equity split. The default form for two-founder start-ups.
• Sociedade Anónima (SA). Public limited company, minimum share capital €50,000, minimum five founders (or a single founder if that founder is the State or a sociedade anónima itself). Heavier governance — conselho de administração, fiscal único or conselho fiscal, mandatory external audit above certain thresholds. The right form for a business raising institutional capital, not for a three-person consultancy.

In practice, roughly 95 per cent of expat-founded Portuguese entities in 2025 were either unipessoais by quotas or ENIs (INE/IRN annual registry data). Everything below assumes you're making that choice.

2. ENI vs Sociedade Unipessoal: The Decision Tree

The trade-off, in plain English:

• Go ENI if your expected annual turnover is below about €50,000–€70,000, your services are low-risk (no employees, no inventory, no real-estate operations), and your personal liability exposure is tolerable. The simplified IRS Category B regime taxes 75 per cent of professional-services revenue and 15 per cent of commercial-sales revenue as presumed profit, and you're done with accounting obligations beyond the livro de registo. Below €15,000 turnover in the first year and €14,500 subsequently you're IVA-exempt under Article 53 CIVA.
• Go unipessoal if your turnover will be higher, if you plan to hire employees, if you intend to raise external capital, if you're working with bigger B2B clients who prefer invoicing a pessoa colectiva, or if you want to separate personal and business assets. You get IRC at a flat 17 per cent on the first €50,000 of taxable income (for a PME — pequena e média empresa) and 20 per cent above that (2026 rates), plus municipal derrama, plus state-level derrama on profits above €1.5 million.

There is no fixed cross-over point, but accountants will routinely recommend the sociedade form once expected net annual profit exceeds around €20,000–€25,000 — the level at which the marginal IRS rate catches up with the IRC rate and the liability protection becomes proportionately more valuable.

3. What You Need Before You Register

Before you can open a company in Portugal you need, for every shareholder, director and gerente (managing partner):

• NIF — Portuguese tax number. If you are EU/EEA you can obtain one directly at a Finanças desk; if you are third-country (UK, US, Brazil post-Brexit-style residency rules, Canada, Australia, etc.) you need a representante fiscal until you have a Portuguese residency title or a Portuguese address.
• Portuguese address for the company seat (sede). A rented office, a coworking space that offers a morada fiscal, a virtual-office provider, or the gerente's home. The sede determines which Serviço de Finanças and which municipal derrama rate applies.
• CAE code — Código de Actividade Económica — the five-digit INE classification that identifies your main activity. You can pick up to three secondary CAEs; the primary CAE drives your IVA regime, your labour-law collective agreement and parts of your tax regime.
• Company name — either chosen from the RNPC pre-approved list at Empresa na Hora, or individually approved via a Certificado de Admissibilidade issued by the Registo Nacional de Pessoas Colectivas (typically 2–4 working days, €75, valid 3 months).
• Bank account — a Portuguese bank account in the company's name, into which the subscribed capital is deposited. Since the 2011 reform that reduced minimum capital to €1 per share, the deposit is largely formal — but the bank KYC is still the single-longest step of the whole process, often taking two to three weeks.
• TOC / contabilista certificado. Sociedade forms legally require a Portuguese contabilista certificado (the old TOC) registered with the OCC. Most expat founders engage one before incorporation to process the post-registration obligations immediately.

4. The Empresa na Hora Desk Itself

Empresa na Hora is a one-stop-shop scheme run by the Instituto dos Registos e do Notariado (IRN). You walk in with all shareholders physically present (or with certified powers of attorney), pick a pre-approved name, choose one of the pre-approved pactos sociais, pay the €360 registration fee (or €300 online via the Empresa On-Line portal), and walk out — typically in 60 to 90 minutes — with:

• The Certidão Permanente of the company, valid 12 months, with the Ponto Único de Empresa code you'll use everywhere.
• Company NIPC (Portuguese company tax number).
• Registration with the Tax Authority (AT), with the Actividade opened and the CAE codes on file.
• Registration with Segurança Social.
• Publication of the constitution in the Diário da República electrónico.
• The statutory Livro de Actas and Livro de Actas das Assembleias Gerais.

Limits to the Empresa na Hora route: (1) you must accept one of the pre-approved pactos sociais, which are boilerplate and may not fit a bespoke shareholder arrangement; (2) you cannot use this route if any shareholder is a foreign legal person without a Portuguese branch; (3) certain regulated activities (credit institutions, insurance companies, law firms as SCLPs, SAs and investment funds) are excluded.

If any of those apply to you, the route is the classic one: a Certificado de Admissibilidade from RNPC, a notarial deed (or an RNPC-registered articles of association), registration at the Conservatória do Registo Comercial, and Finanças/Segurança Social registrations via the Portal da Empresa.

5. Empresa On-Line: 100% Digital, 24 Hours

Since 2023 the Empresa On-Line portal (portaldaempresa.pt) has accepted fully online company constitution using Chave Móvel Digital or Cartão de Cidadão signature. No physical presence, no desk, no queue — if you have a qualified electronic signature and all founders have Portuguese digital identity. Typical end-to-end turnaround: 24–48 hours. Fee: €300. For expats who already hold CC or CMD, this is the cheapest and fastest route. The hard blocker remains qualified digital signature — most third-country founders will not have one on arrival.

6. IRC, IRS and the Social-Security Architecture

Once the company is incorporated, the tax machinery kicks in. A quick map:

• IRC. Corporate tax. Headline rate 20% (2026), reduced to 17% on the first €50,000 of taxable profit for SMEs (PME as defined in Recomendação 2003/361/CE), plus a derrama municipal of up to 1.5% set by each Camara Municipal, plus a derrama estadual of 3%–9% on profits above €1.5m.
• IVA. Value-added tax. Mainland standard rate 23%, intermediate 13%, reduced 6%; Azores and Madeira rates lower. Under the general regime you charge IVA on every invoice and declare it quarterly (if turnover < €650,000) or monthly (> €650,000). Article 53 CIVA exempts supplies below the €15,000 / €14,500 threshold from IVA entirely.
• Withholding on invoices. Clients who are Portuguese legal persons withhold 25% IRS / IRC on professional-services invoices under Article 101 CIRS. The withholding is an advance payment, reconciled at year-end on the Modelo 3 (for IRS) or Modelo 22 (for IRC).
• Segurança Social — on the gerente. A remunerated gerente is subject to the standard 11% employee + 23.75% employer Taxa Social Única on their salary. An unremunerated gerente pays a fixed monthly contribution based on 1 IAS (€522.50 in 2026) as a membro dos órgãos estatutários, at 28.3% — roughly €148/month.
• Segurança Social — on ENI. Category B workers pay a 21.4% contribution on a contribution base equal to 70% of the quarter-relevant invoicing (professional services) or 20% (commercial sales). First 12 months of activity exempt by default.

7. Post-Incorporation Checklist

The work is not finished when the certidão permanente prints. Within the first month you must:

1. Open the company's conta corrente at Finanças by assigning a contabilista certificado through the Portal das Finanças.
2. Enrol the gerente in Segurança Social Direta (Sistema dos Órgãos Estatutários).
3. Submit the Declaração de Início de Actividade at Finanças if not already bundled with Empresa na Hora.
4. Choose IVA regime (monthly or quarterly).
5. Contract compulsory Seguro de Acidentes de Trabalho if you have, or plan to have, any employee — including the remunerated gerente.
6. Register with the Autoridade para as Condições do Trabalho (ACT) if you intend to hire.
7. If you will be a data controller, register with the CNPD.
8. If your CAE is a regulated activity (turismo, transporte, construção civil, alimentação, etc.), obtain the sectoral licence before trading.

8. Hiring Your First Employee

Portuguese labour law is protective by EU standards and the 2026 Trabalho XXI reform, currently before UGT on 24 April and likely to go to Parliament in the summer, is unlikely to change that materially for small employers. Core numbers for the first hire:

• Minimum wage — €920/month in 2026 (14 monthly payments + holiday and Christmas allowance = €12,880/year gross, plus €23.75% employer Social Security = total annual cost around €15,940).
• Standard probationary period — 90 days for open-ended contracts, extended to 180 days for cargos de confiança.
• Holiday entitlement — 22 working days per calendar year.
• Compulsory seguro de acidentes de trabalho — typically 1.1% of gross payroll, paid to a private insurer.
• Fundo de Compensação do Trabalho contribution — 1% of gross wage, paid for each open-ended contract signed from October 2013 onward.

9. The Personal Tax Side for the Founder

A Portuguese-tax-resident founder of a sociedade por quotas faces three layers:

• IRC at the company level (17% / 20% on retained profit).
• IRS on salary paid as gerente — taxed under Category A on the ordinary IRS scale, with employee Social Security of 11%.
• IRS on dividends paid out of after-tax profit — taxed at 28% withholding (final, unless you opt for English), or as part of the IRS general income with 50% inclusion for tax-resident shareholders who opt for englobamento.

If the founder is resident under the IFICI regime, the first two layers interact differently — eligible scientific-and-technical Category A income is taxed at a flat 20% for ten years, and foreign-source dividends are exempt under a participation-exemption-style rule. The IFICI regime interacts with sociedade by quotas structure in non-obvious ways — get specialised advice before electing it.

10. Common Mistakes

• Opening the company without first confirming the CAE code. Changing CAE mid-stream is painful and triggers a fresh IVA regime choice.
• Assuming the €1 share capital is purely formal. Portuguese banks will typically require a real capital deposit of €1,000–€5,000 before opening a corporate account.
• Skipping the contabilista certificado engagement until after the first trading month. Filing obligations start immediately; late filings trigger coimas from day one.
• Over-relying on a virtual-office sede. Finanças inspectors can — and do — check whether the sede matches reality; a repeatedly unattended sede is a flag for IVA-refund audits.
• Not registering the UBO (Registo Central do Beneficiário Efectivo) within 30 days of incorporation. The fine is up to €50,000.
• Treating the unipessoal gerente's monthly Social Security as optional. The minimum contribution kicks in automatically on incorporation; unpaid contributions accrue interest and penalties.

11. A Realistic Cost Sheet for 2026

• Empresa na Hora fee — €360 (in-person) or €300 (Empresa On-Line).
• Initial capital deposit — €1 legal minimum, €1,000–€5,000 bank practice minimum.
• Contabilista certificado — €75–€200 per month depending on volume.
• Virtual office / coworking sede — €30–€100 per month.
• RCBE initial registration — free, annual confirmation free online.
• Optional Certificado de Admissibilidade (bespoke name) — €75.
• Optional notarial deed for bespoke pacto social — €150–€500 at a Cartório Notarial.
• First-year IRC if profit ≤ €50,000 — 17% plus municipal derrama plus IVA on supplies.
• Unremunerated gerente Segurança Social — €148/month fixed.

12. When to Hire a Portuguese Lawyer

You do not need a lawyer to register a vanilla unipessoal at Empresa na Hora. You do need one if: you have multiple founders with a non-trivial equity split; you are building a vesting schedule; you are accepting external investment; you are converting an existing foreign-parent company into a Portuguese sociedade; you are opening a regulated-activity company; or you are taking the Golden Visa / Incentivo à Capitalização das Empresas capitalisation-incentive route. Portuguese corporate lawyers bill €200–€350 per hour on that work; a two-founder LDA with vesting typically costs €2,500–€4,500 end-to-end.

13. Who Can Be a Founder?

Portugal imposes no residency requirement on shareholders or on gerentes. A non-resident EU citizen can open an unipessoal entirely at distance with a Portuguese representative. A non-EU third-country national can too, provided they have a Portuguese NIF (via representante fiscal) and a Portuguese bank account. The founder's residence status does, however, change the sede choice and the IRC/IRS interaction — a non-resident gerente who is paid a salary by the Portuguese LDA triggers a Portuguese Category A liability on that salary, and a Portuguese Social Security liability unless the gerente is covered by a home-country A1 certificate under the EU coordination regulation or a bilateral agreement.

14. Closing the Company

Closing is slower than opening. A voluntary dissolution runs through an extraordinary general meeting, a six-month minimum liquidation period (shorter under the simplified regime if the company has no creditors), a final Declaração de Cessação de Actividade at Finanças and a final Modelo 22 IRC. Budget two to four months and €500–€1,500 in contabilista fees.

15. A Realistic 30-Day Timeline

• Day 1–3: All founders obtain NIFs and, if necessary, a representante fiscal is appointed.
• Day 2–5: Engage contabilista certificado; agree sede; pick CAE code.
• Day 5: Walk into Empresa na Hora with passports, NIFs, IBAN. Company exists 90 minutes later.
• Day 5–20: Open corporate bank account (KYC is the gating item).
• Day 20–25: Deposit capital, enrol gerente in Segurança Social, register RCBE, activate Finanças Portal access with contabilista.
• Day 25–30: First commercial invoice issued, first IVA obligation set.

Portugal's company-formation machinery is genuinely efficient — one of the three fastest incorporation regimes in the EU on the 2024 World Bank and EU Commission benchmarks. The bureaucracy that trips expat founders up is almost never at the Empresa na Hora desk; it is at the bank-account-opening stage, on the RCBE and Finanças compliance calendar, and in the Segurança Social architecture around a remunerated gerente. Engage a contabilista certificado on day one, pick the right legal form for your turnover and liability profile, and the country delivers what it advertises: a company, in 90 minutes, for the price of a mid-range restaurant dinner.
