LDA company vs sole trader in Portugal: which should you choose?

Sooner or later, every successful freelancer in Portugal asks the same question: should I keep invoicing as a self-employed individual, or set up a company? And every founder moving to Portugal asks the mirror image: do I really need a company, or can I just open atividade?

The two main options are working as a sole trader — a self-employed individual (trabalhador independente, or formally Empresário em Nome Individual, ENI) — or incorporating an LDA (sociedade por quotas, a private limited company; a single-owner version is called a unipessoal LDA). Neither is universally better. Here is how they compare on the dimensions that actually matter.

Setup and running costs

Sole trader: registration is free and takes an hour online — you open atividade with Finanças (the tax office) and start invoicing recibos verdes. Under the simplified tax regime there is no mandatory accountant, and compliance can be genuinely light.

LDA: incorporation is fast in Portugal (the Empresa na Hora "company in an hour" service is real) and minimum share capital is symbolic — as little as €1 per shareholder, though a sensible working capital is advisable. But a company must have organized accounting with a certified accountant (contabilista certificado) from day one, file corporate returns, and maintain statutory records. Budget for monthly accounting fees plus incorporation costs, bank account and registered address.

Rule of thumb: the sole trader's fixed costs are near zero; the LDA's are a permanent monthly line item.

Taxes: where the crossover happens

Sole trader: your profit is taxed as personal income under IRS (Portuguese personal income tax) at progressive rates. Under the simplified regime, tax applies to a coefficient of revenue (typically 75% for professional services) rather than actual profit. Simple, but at higher incomes the progressive brackets bite hard.

LDA: the company pays IRC (corporate income tax) on its profits — the standard rate has been coming down in recent years to around 20%, with a reduced rate for SMEs on the first tranche of profit (check current rates, as the government has been lowering them year by year). But corporate tax is only half the story: getting money out of the company — as salary or dividends (dividends carry a 28% flat tax for residents) — triggers a second layer.

The honest summary:

• At modest incomes, the sole trader usually wins — the simplified regime's coefficients and low overhead beat the double layer of IRC plus dividend tax and accounting fees;
• At higher incomes, the company can win — you control how much you pay yourself, retain earnings at corporate rates, deduct real business expenses fully, and plan distributions;
• The crossover point depends on your expenses, how much you need to live on, and social security effects — it is a calculation, not a slogan.

Tip: Do not incorporate for tax reasons based on a forum post. Ask for a side-by-side projection on your real numbers — revenue, expenses, and the salary you actually need — before committing to a structure with monthly fixed costs.

Liability and credibility

• A sole trader has unlimited liability: business debts are your personal debts;
• An LDA limits liability to the company's assets (with exceptions for managers' misconduct and personal guarantees banks often demand anyway);
• Some larger clients, agencies and platforms prefer or require contracting with a company, and an LDA reads as more established. For raising investment, hiring employees, or co-founding with partners, a company is effectively mandatory.

Social security differences

• A sole trader pays self-employed contributions: 21.4% on a base of (usually) 70% of service income, with quarterly declarations — and first-timers get a 12-month exemption;
• An LDA manager (gerente) is covered under a different regime, with contributions based on their declared salary at combined employer + employee rates similar to regular employment, and generally no first-year exemption;
• If you already pay social security elsewhere (as an employee, or abroad under an A1 certificate or totalization agreement), the picture shifts again.

Social security is often the forgotten variable that flips the comparison — include it in any projection.

Conclusion

Start simple unless there is a concrete reason not to: for most freelancers and remote workers arriving in Portugal, sole trader status under the simplified regime is cheaper, lighter and entirely respectable. Incorporate an LDA when the numbers justify it — sustained higher profits, significant deductible expenses, more money earned than you need to withdraw — or when the business itself demands it: partners, employees, investors, or clients who insist on a company.

The decision is reversible but not free to reverse, and the social security and tax interactions are genuinely case-specific. A one-off structuring consultation with an accountant, done on your actual figures, is the right way to choose — and much cheaper than unwinding the wrong structure later.
