Sole Trader or Lda in Portugal: How to Choose

Most people setting up in Portugal should be a sole trader, not a company. It is cheaper, faster, and you can do it yourself in an afternoon. An Lda is the right call for a narrower set of reasons, and they are mostly not the ones people assume.

I went the Lda route for my own company, and the deciding factor was not tax. This is the comparison I wish I'd had in front of me when I was choosing: what each structure actually costs you, what it protects, and the handful of situations where the company is worth the overhead.

Already decided? The sole-trader setup is in the freelancer hub; the Lda setup is its own guide.

The two structures, briefly

• Sole trader (trabalhador independente, TI): you, trading under your own name and NIF. No separate legal entity. This is most freelancers and Recibos Verdes workers.
• Lda (sociedade por quotas): a separate legal entity you own and manage, with its own NIPC, accounts, and tax return. A Unipessoal Lda is the single-owner version.

A note on the SA. You may also have heard of the sociedade anónima (SA), the third company form. For a solo entrepreneur it is almost never the starting point: it needs €50,000 of share capital (an Lda can be set up with €1), at least five shareholders (or one, if that shareholder is itself a company), and a mandatory auditor (revisor oficial de contas, ROC) every year. The corporate tax is identical to an Lda, so there is no tax reason to choose it. Where it genuinely matters is raising serious investment and giving employees real equity: venture funds want tradeable shares, and Portugal's tax-advantaged stock-option regime works cleanly on SA shares but not on Lda quotas. The normal path is to start as an Lda and convert to an SA later, if and when you raise. If you are choosing between sole trader and company today, the SA is not your decision.

Liability: the reason that actually matters

This is the one that decided it for me. As a sole trader there is no line between you and the business: a debt, a lawsuit, or a client harmed by your work reaches your personal assets. An Lda draws that line. The company is liable to the limit of its own assets, and your personal savings and home sit behind it (barring fraud or personal guarantees you sign).

For low-risk service work this rarely bites. But if your work can cause real financial harm to someone, if you carry stock or debt, or if one bad outcome could exceed what you can absorb personally, the limited-liability wall is worth paying for on its own. Tax is a rounding error next to "could this take my house".

Tax: "low IRC" is a trap

The seductive pitch for an Lda is the headline rate: IRC is 15% on the first €50,000 of profit (and 19% above that), where a sole trader pays personal IRS at progressive rates up to 48%. It looks like a landslide. It is not, for one reason: the money is still inside the company.

• Sole trader: under the regime simplificado you are taxed on a fixed slice of revenue (for listed professions including IT, a 0.75 coefficient, so 75% of gross is taxable) at IRS rates, plus Social Security of roughly 15% of gross. One layer, and it is yours immediately.
• Lda: the company pays IRC on profit, then you pay again to get the money out, as salary (IRS plus 34.75% Social Security) or dividends (28% flat). Two layers. As a rough shape: a company around €60,000 might pay under €1,000 of corporate tax but €10,000 to €15,000 more once the profit is extracted, depending on the salary-versus-dividend mix.

You may see a 12.5% startup rate quoted. It is real, but it is not a reason to incorporate: you have to be a formally certified startup to get it, which means ANI innovation certification or a venture-capital round, it applies to the same first €50,000 of profit, and it saves at most €1,250 a year over the 15% rate. Going through certification or raising money to shave 2.5 points off the first €50k is not worth the work for an ordinary company. Treat it as a footnote, not a feature.

So, honestly: at low-to-moderate solo income the sole trader is usually cheaper all-in once you count extraction and overhead. The Lda's tax edge only really shows up at higher retained profit, and even then the salary-versus-Social-Security question dominates. The full modeling is in Part 1 and Part 2. Do not pick the structure on the headline rate.

The Lda's real tax edge: benefits, not the rate

If there is a genuine tax win in the company, it is not the IRC rate; it is the benefit suite a salary unlocks. Pay yourself (or a co-owner) properly and the company can route real spending through pre-tax, Social-Security-free, deductible euros, where a sole trader pays for the same things out of fully-taxed personal cash. The catch is in that sentence: it only works once there is a real salary, and the best parts need two genuinely remunerated workers, not a lone owner.

• Available even to a one-person Lda (a single salaried gerente): a meal card (cartão refeição) at up to €10.46/day tax-free, professional training, and work equipment (laptop, phone). Modest, but the meal card alone is around €2,000 a year of tax-free value.
• Needs at least two genuinely remunerated workers. The law requires the benefit be offered to the "generality of workers" (generalidade dos trabalhadores), so a single owner-gerente does not count, but a couple both on the payroll does. This unlocks health insurance (deductible for the company, untaxed for the worker, and it extends to your spouse and dependent children, the headline one for a family Lda), life or disability insurance and a pension (PPR), and childcare or education vouchers (vale infância, vale educação).
• A company car, if you would buy one anyway: an electric car at or below €62,500 gets 0% autonomous tax, full VAT recovery, and the full depreciation ceiling, advantages a combustion car mostly cannot reach. Private use is taxed as a benefit in kind (around 9% of the car's value a year), so it is a benefit priced as one, not a free private car.

The one trap: this whole suite needs you on a genuine salary, which collides with the acumulação Social-Security waiver (zero gerente salary, available if you already contribute as a sole trader). It is the SS waiver or the benefits, not both. You pick.

I went through all of this for my own company. The first-person numbers (health insurance, the electric car, and the shareholder-loan trick for getting cash back out tax-free) are in Part 2. To put your own figures in, the Lda Tax Benefits Calculator models the whole suite (which benefits you unlock, the 15%-of-payroll cap, the car) for your salary and household.

Cost and admin overhead

• Sole trader: opening activity is free, you can file your own VAT and IRS, and a certified accountant is not legally required on the simplified regime. Realistic fixed cost: near zero, plus optional help.
• Lda: a contabilista certificado is mandatory (roughly €100 to €150 a month), formation costs €360 (or €220 online), and you owe organized accounting, an annual IRC return and IES, monthly sócio-gerente Social Security, and the RCBE. Realistic baseline: around €3,700 a year before the business earns a cent.

That ~€3,700 floor decides most cases. It is trivial for a profitable company and crippling for a side income.

Growth and optionality

An Lda is something you can sell, raise money into, or bring a co-founder onto. A sole-trader activity is just you; it cannot be transferred or part-owned. If you are building something you might sell, take investment in, or scale with partners, the company supports it. For a solo practice you intend to keep solo, that optionality is worth nothing.

Simplicity and speed

A sole trader can be set up the same afternoon, online, by yourself. An Lda is a multi-step process (formation, accountant, abertura, RCBE, Social Security, bank) that, as a foreigner, can take weeks. If you just want to start invoicing next week, that alone may settle it. The Lda path and its pitfalls are in the setup guide.

Which one is you

• Freelance designer, ~€30k, solo, low risk: sole trader. The Lda overhead would eat the tax it saves, and you do not need the liability wall.
• Building a product where a mistake could cost a client real money (fintech, tax, health, anything money- or safety-critical): Lda, almost regardless of income. The wall is the point; tax is secondary.
• Scaling: hiring, raising, or planning to sell: Lda. You need an entity that can hold those relationships and be transferred.
• In between (solid solo income, some risk, no plans to scale): run the all-in numbers (Part 1 and Part 2). The sole trader often still wins until profit is high and retained; do not assume the company is the "grown-up" choice.

Start small, switch later

You are not locked in. The low-regret path is to start as a sole trader and incorporate an Lda only when a concrete reason appears: liability you can no longer carry personally, a co-founder or investor, or retained profit high enough that the tax math finally favours the company. Switching means opening the Lda, moving your activity across, and winding down the sole-trader activity. It is paperwork, not a reset, and you keep trading throughout. Starting as a company "to look serious" is the most common over-engineering mistake: the cost floor is real and the credibility gain is mostly imagined.
