Portugal Business Registration Guide 2026 — Lda, SA, Sole Trader

Sole Trader (Empresário em Nome Individual)

The empresário em nome individual (ENI) is the simplest business structure in Portugal, ideal for freelancers, small service providers, and independent professionals. There is no minimum capital requirement. Registration involves: obtaining a NIF (Número de Identificação Fiscal) if you do not already have one; registering as a self-employed worker (trabalhador independente) with both the Autoridade Tributária (for IRS and VAT) and Segurança Social (for social security contributions); and selecting the appropriate CAE (Classificação das Actividades Económicas) code for your activity. The registration process is completed at your local Finanças (tax office) or through the Portal das Finanças online. Once registered, you issue green receipts (recibos verdes) for your services and file quarterly VAT returns (if applicable) and annual IRS declarations. The sole trader bears unlimited liability — personal assets are at risk for business debts. Tax is calculated under IRS at progressive rates (13–48%) on business profits, rather than IRC (corporate tax). You can opt for the regime simplificado (presumptive taxation) if your turnover is below €200,000 per year, which applies a coefficient of 0.75 to service income (i.e., only 75% of income is taxable). The regime de contabilidade organizada is mandatory for turnover exceeding €200,000 or if you opt in voluntarily.

Lda (Sociedade por Quotas — Quota Company)

The Lda (sociedade por quotas) is the most common corporate structure for small and medium-sized businesses in Portugal. Key features: minimum share capital of €1 (since 2023 reform, previously €5,000); at least two partners (sócios) — if you are a sole founder, you need a second partner (can hold a single €1 quota); liability is limited to each partner's capital contribution; and management is conducted by one or more gerentes (managers) who can be partners or third parties. Registration steps: (1) choose a company name and check availability via the RNPC (Registo Nacional de Pessoas Colectivas) online portal; (2) prepare the memorandum of association (contrato social); (3) deposit the share capital in a Portuguese bank account; (4) register the company with the Commercial Registry (Conservatória do Registo Comercial) — this can be done via the Empresa na Hora service (company in one hour) for a simplified process; (5) obtain the NIPC (Número de Identificação de Pessoa Colectiva); and (6) register for VAT (IVA) and social security as an employer. The total cost is typically €360–€500 via Empresa na Hora. Lda profits are subject to IRC (corporate tax) at 21% (17% for SMEs on the first €25,000 of taxable income), plus municipal surcharge (derrama) of up to 1.5% and state surcharge of up to 9% on high profits.

SA (Sociedade Anónima — Share Company)

The SA (sociedade anónima) is designed for larger businesses requiring access to capital markets. Key features: minimum share capital of €50,000 (at least 70% paid up at incorporation); at least 5 shareholders (accionistas); liability is limited to the value of subscribed shares; governance includes a board of directors (or a single director), a supervisory board or audit committee, and a statutory auditor (revisor oficial de contas). The SA structure is more regulated and expensive to maintain than an Lda, with stricter reporting and audit requirements. Registration follows a similar process to the Lda but with additional formalities: appointment of a statutory auditor, publication of the incorporation deed in the Commercial Registry, and registration with the Comissão do Mercado de Valores Mobiliários (CMVM) if shares are publicly traded. The cost of incorporation through Empresa na Hora is higher — approximately €500–€1,000 depending on complexity. SA companies are also subject to IRC at 21% (standard rate, with SME relief not applicable) plus municipal and state surcharges. SAs are required to publish annual accounts. This structure is uncommon for startups and SMEs unless they plan to raise significant equity capital or prepare for an IPO.

Registration Process and Empresa na Hora

Portugal offers a streamlined company registration service called Empresa na Hora (Company in One Hour), available at any Conservatória do Registo Comercial and online through the Portal do Cidadão. With Empresa na Hora, you can: choose from a list of pre-approved company names (or bring your own certified name); select a standard memorandum of association template; make the share capital deposit (if applicable); and complete registration in approximately one hour. The service costs around €360 for an Lda and €500 for an SA, including all registry fees, publication, and initial taxes. You will receive: the company's registration certificate, NIPC (tax ID number), and access to the company's electronic folder (pasta electrónica da empresa) for ongoing compliance. For sole traders, registration is even simpler — completed at your local Finanças office in one to two days at no cost. After registration, all businesses must: register for VAT (IVA) if turnover exceeds €12,500 per year (or voluntarily); register as an employer with Segurança Social; and subscribe to the Centro de Arbitragem for commercial dispute resolution (mandatory for most businesses). Foreign entrepreneurs can register a company without residing in Portugal, but a Portuguese tax representative is required for non-EU/EEA nationals.

Tax Obligations by Business Structure

Tax obligations vary significantly by structure. Sole traders (ENI) file: annual IRS (Modelo 3) return (by June/July), quarterly VAT returns (if turnover exceeds €12,500), and annual social security contributions (calculated on quarterly income). Sole traders cannot deduct as many business expenses as corporate structures. Lda companies file: annual IRC (Modelo 22) return (by May), quarterly or annual VAT returns, quarterly/annual withholding tax (Modelo 10) for employees, annual tax asset declarations (Modelo 25/26), and monthly/annual labour and social security declarations via Segurança Social Direta. Lda companies also prepare and file annual accounts with the Commercial Registry. SA companies have all Lda obligations plus: appointment of a statutory auditor, publication of audited accounts, and (if publicly traded) compliance with CMVM reporting. All structures must keep proper accounting records in Portuguese, follow the SNC (Sistema de Normalização Contabilística), and retain records for 10 years. The standard IRC rate is 21% (17% for SMEs on first €25,000 profit). For sole traders, profits are taxed under IRS at 13–48% progressive rates — which can be higher than IRC rates if your income is substantial.

Compliance and Ongoing Costs

All business structures in Portugal have ongoing compliance requirements. Sole traders have lower fixed costs: an annual accountant (contabilista certificado) costs roughly €50–€150 per month for basic compliance. Lda companies face higher costs: mandatory accountant (€150–€400 per month), annual commercial registry renewal fee (approximately €50–€100), publication of annual accounts (€150–€300), and potentially a revisor oficial de contas (ROC) if the company exceeds two of three thresholds (€1.5M turnover, €750K balance sheet, 10 employees). SA companies have the highest costs: statutory auditor (€3,000–€10,000 per year), board expenses, and CMVM fees for publicly traded companies. All companies must maintain a pasta electrónica da empresa where documents are filed. Penalties for non-compliance: late filing of IRC Modelo 22 (€75–€225), late VAT returns (€25–€125 per return), and failure to file annual accounts (€500–€3,000). Social security non-compliance can result in fines of €300–€9,000. It is mandatory to have a contabilista certificado (certified accountant) for all corporate structures (Lda and SA). The accountant is responsible for submitting all periodic tax declarations. For sole traders, an accountant is highly recommended but not legally required if turnover is below certain thresholds.

Yes — any foreign national can register a company in Portugal. Non-EU/EEA nationals need a Portuguese tax representative. You do not need to reside in Portugal to incorporate a company, but you must be registered for tax purposes.

What is the best structure for a freelancer moving to Portugal?

Most freelancers start as a sole trader (ENI) due to simplicity and lower costs. If you earn over €50,000–€70,000 per year, an Lda may be more tax-efficient (IRC at 17–21% versus IRS at up to 48%).

Approximately one hour if you attend in person with all required documents and a pre-selected name. Online registration can take 1–3 business days.

Do I need a Portuguese bank account to register a company?

Yes — for Lda and SA structures, you must deposit the share capital in a Portuguese bank account and obtain a certificate from the bank. Some banks allow online account opening for non-residents.

Typically €2,000–€6,000 per year, including accountant fees (€180–€480/month), registry fees, annual accounts publication, and other compliance costs. Sole traders cost significantly less.
