Sole trader or limited company in Spain: when it pays off, and the catch behind the 25%

Sole trader or limited company: where the real threshold lies

Is it worth setting up a limited company in Spain, or is it better to register as a self-employed worker (autónomo)? The short answer: it depends on how much you bill and, above all, how much you need to spend. The consensus circulating online puts the tipping point at around €50,000 in gross profit, when the effective income tax rate (IRPF) exceeds the corporate tax rate. But that calculation has a hole almost nobody mentions: money kept in the company isn't yours until you take it out.

The dividend that eats up the tax advantage

In theory, beyond a certain volume it pays to be taxed at the corporate rate instead of climbing the income tax brackets. The problem arises when the shareholder wants to use that profit. If it's extracted as a dividend, another 18% in tax is added, bringing the combined rate back to the equivalent of the top income tax bracket above €53,000 of gross income. The advantage evaporates.

There are intermediate routes: paying expenses in the company's name, per diems, health insurance. All of that exists, yes. So does the tax inspector, who demands proof of who, when, how, where and why. Without paperwork, the per diem becomes a benefit in kind, with the corresponding social security contributions, fines and interest.

Limited liability isn't a perfect shield

The big argument for incorporating a company is protecting your personal assets. Banks, however, know the trick: when the director is also the majority shareholder, the risk department assumes they will personally guarantee the deal. The bridge between assets gets built again, this time by contractual means.

And there's more. Spain's Companies Act allows claims against a director for damage caused by acts contrary to the law or the company's bylaws, or for breaching their duties. The protection exists, but it isn't free or automatic.

The director who hires themselves

In a single-member company, the sole shareholder takes on the directorship and therefore remains obliged to pay self-employed social security contributions. They draw a salary from the company, but don't have the same rights as an employee. The figure of the self-contract raises legal questions nobody has fully settled.

The self-employed route is cheaper to set up and to wind down: a morning between the tax office and Social Security, two if the paperwork isn't in order. Incorporating a company requires a notary, a business registry and, probably, a consultancy. Recurring administrative costs also add up.

The family payroll trap

Hiring your partner to split payrolls and reduce income tax sounds great until the tax office asks questions. If you share a home, the argument of genuine work gets shaky. The tax break exists on paper; in practice, the burden of proof falls on whoever applies it.

With the current support schemes for the self-employed, many start with the simple route. A single-member limited company makes sense when the volume, the risk or the structure justify it. Not before. And certainly not for the tax savings the blogs promise.
