When the shareholder and the director are the same person, Spain makes them autonomo.
Not always — and the line is not where most founders assume. It is drawn by an arithmetic test on your shareholding, and crossing it replaces an employment relationship you thought you had with a self-employed status that costs a fixed 448 euro a month in 2026, whether the company pays you anything or not.
What is an autonomo societario?
A person who works for a company they substantially own, and whom Spanish law therefore treats as self-employed rather than employed. Article 305 of the General Social Security Law puts into the self-employed regime, RETA, anyone who performs management functions as a director, or provides services to a capital company, while holding effective control of it. Control is the whole question, and the law defines it by percentages rather than by what your contract says.
The situation this describes is the most common founder structure in Spain: one person owns the company and one person runs it, and they are the same person. It feels like a single role. Spanish social security law sees two separate questions — what you own, and what you do — and only the intersection of both produces the answer.
What makes this worth a careful reading rather than a glance is that the consequences are not marginal. They reach the monthly cost, the deductibility of your own pay, whether you can hold an employment contract at all, whether you are entitled to anything if the business fails, and whether a flat tax regime you were counting on is available. And in 2026 the cost side changed sharply.
Three places you can land.
Before the test itself, the three possible outcomes, because people often do not realise there is a middle one.
Outcome two is not "employment" in the way people expect either.
Being in the general regime as an assimilated director sounds like being an employee, and for contribution purposes it broadly is. But the exclusion from unemployment cover follows you there too. The practical difference between outcomes one and two is cost and administration, not protection — neither gives you the safety net an ordinary employee has.
The control test, precisely.
The law does not ask whether you control the company as a matter of fact. It presumes control in three defined situations, and leaves you to disprove it if you can. These are the thresholds.
| Your position | Management functions needed? | Result |
|---|---|---|
| You hold 25% or more of the capital | Yes — management and direction functions | Control presumed. RETA. |
| You hold 33.33% or more | No — the shareholding alone does it | Control presumed. RETA. |
| 50% or more held by you plus cohabiting relatives to the second degree | No | Control presumed. RETA. |
| Below all three, with executive functions, paid | Yes | General regime, assimilated. No unemployment cover. |
| Shares only, no functions | No | Nothing arises. |
Read the first two rows together, because the relationship between them is where the confusion lives. Twenty-five per cent is not the threshold on its own. A quarter of the capital triggers RETA only if you also carry management and direction functions. But a third of the capital triggers it regardless of what you do — a passive shareholder at 33.33% who provides any service to the company is caught, while an active managing shareholder at 20% is not.
Your family's shares are added to yours.
For the 50% test, the law aggregates the holdings of relatives to the second degree of consanguinity, affinity or adoption with whom you live. Parents, children, siblings, grandparents, grandchildren and the equivalent by marriage. Two siblings holding 30% each and sharing a home are inside the presumption even though neither reaches a third individually. Splitting a shareholding across a household does not avoid the test; it is the specific arrangement the rule was written to catch.
Four structures, four answers.
| Structure | Analysis | Outcome |
|---|---|---|
| Sole founder, 100%, sole administrador | Both tests cleared several times over | RETA, unavoidably |
| Two co-founders, 50/50, both administradores | Each exceeds a third on their own | Both in RETA |
| Four founders at 25% each, all managing | 25% plus management functions | All four in RETA |
| Hired CEO with 10%, founders hold the rest | Below every threshold, executive functions, paid | General regime, assimilated |
| Investor with 40%, no involvement | Above a third, but performs no services | Nothing — the test needs both limbs |
| Founder at 20%, managing, spouse holds 35% | Cohabiting second-degree aggregation reaches 55% | RETA |
The last row is the one that catches people who believed they had planned around this. The fifth row is the one that surprises in the other direction: a substantial shareholder who genuinely does nothing for the company has no obligation, because the article requires both control and the performance of functions or services.
What it costs, and what changed in 2026.
This is where the analysis stops being theoretical. Ordinary self-employed people in Spain contribute on bands set by their real net earnings, running from roughly 200 to 590 euro a month. The autonomo societario does not use that floor.
About 313 euro a month
The minimum contribution base for company directors sat at 1,000 euro, producing a floor of roughly 313 euro a month regardless of what the company actually paid you.
About 448 euro a month
The minimum base for autonomos societarios was aligned with the general regime minimum, rising to 1,424 euro. At the general rate of about 31.5%, including the intergenerational equity charge of 0.9%, the floor became roughly 448 euro — an increase of some 135 euro a month, or about 43%.
It is a floor, not a calculation on your income.
An ordinary autonomo earning very little pays at the bottom of the real-earnings table. A shareholder-director earning very little still pays the societario minimum. A company in its first year, pre-revenue, with a founder drawing nothing, owes roughly 5,400 euro a year in social security for that founder. That figure belongs in the cash plan from month one, and it is the single most common omission we see in a founder's first budget.
One genuine mitigation exists, and it is widely believed to be unavailable. It is not.
The reduced starting rate does apply to shareholder-directors.
For years the social security administration refused the tarifa plana to autonomos societarios, and a great deal of published guidance still says they are excluded. The Supreme Court settled it against that position, in a judgment of December 2019 and the line of decisions that followed. A new shareholder-director registering in RETA for the first time can access the 80 euro monthly rate for the first year, and for a second year where earnings stay below the minimum wage — subject to the ordinary conditions, including no outstanding debts to social security or the tax authority.
The difference between 80 and 448 euro a month over a first year is about 4,400 euro. It is worth checking whether your adviser assumed the old position.
Why you cannot simply give yourself an employment contract.
The instinctive workaround is to sign an employment contract with your own company for your management work, and let that contract define the relationship. Spanish law does not permit the result that is being sought, and the doctrine that blocks it was reaffirmed very recently.
The mercantile relationship absorbs the employment one.
Where senior management functions and membership of the company's administrative body are held by the same person, the relationship is characterised as mercantile, and it swallows any parallel employment relationship. There are not two links; there is one, and it is the corporate one. An employment contract covering the same management duties does not create a second relationship — it is absorbed.
In November 2025 the Supreme Court's conflicts chamber confirmed the doctrine remains fully in force, expressly rejecting the argument that European Court of Justice case law had displaced it. The court's reasoning was that the European decisions define "employed worker" for the purposes of particular social directives, and do not reach into domestic characterisation of the relationship. Anyone who was told in 2024 that this doctrine was on its way out was told something that has since been contradicted.
The consequences follow directly. No dismissal, because there is no employment to terminate — a director is removed by the shareholders, at any time, generally without compensation unless the company agreed otherwise in advance. No severance calculation. No unemployment benefit afterwards. No recourse to the wage guarantee fund if the company becomes insolvent. Disputes go to the commercial courts, not the labour courts.
A genuinely separate employment role
Where a person performs ordinary work distinct from management — a working shareholder who is also a developer, a salesperson, a technician — that work can sit in a real employment relationship alongside the corporate office. The separation has to be real: different duties, evidenced, not a relabelling of the same management activity.
A contract for "managing the company"
A senior management contract covering the same functions the corporate office already covers is absorbed. It will not produce employment protection, it will not change the social security regime, and relying on it is how founders discover the doctrine at the worst possible moment.
Getting paid, and keeping the deduction.
Separate from the social security question, and equally capable of going wrong: how the company pays you, and whether that payment reduces its tax bill.
The deduction is now defensible. The formality is still worth doing.
The case law removes an unfair outcome; it does not make the articles irrelevant. An inspection still starts from what the articles say, and a founder relying on litigation to win a point that a properly drafted clause would have avoided is spending money to fix something that should never have been broken.
Where this collides with the impatriate regime.
Founders relocating to Spain frequently plan around the flat impatriate rate, and the shareholder-director position interacts with it in a way that is easy to miss.
Arriving as a director of an operating company
Appointment as a director is one of the qualifying routes into the regime. A founder moving to Spain to run a real trading business can normally reach it, subject to the ordinary conditions on prior non-residence and the election deadline.
A holding or asset-owning company, with 25% or more
Where the company is an asset-holding entity rather than a trading one, a shareholding of 25% or more takes the director outside the regime. Property and investment structures run into this constantly, and the shareholding threshold happens to be the same number as one of the RETA triggers — which is a coincidence, not a connection, and a fertile source of confusion.
The broader point is that these tests use similar numbers for entirely unrelated purposes. A 25% holding matters for social security if you manage, and for the impatriate regime if the company is asset-holding. They are separate rules in separate statutes and neither implies the other.
The non-resident director.
A founder who owns and directs a Spanish company from abroad sits differently again. Spanish social security generally attaches to activity carried on in Spain, so a director who does not work here does not usually fall into RETA merely by holding the office.
- Where the work happens. Not where the company is registered, and not where the shares are held.
- Coordination rules or a bilateral agreement. Within the EU, the coordination regulations decide which single system applies. Outside it, the relevant bilateral social security agreement does, if there is one.
- Frequency of presence. A director who is in Spain regularly to run the company is on different ground from one who attends a meeting twice a year.
- The company's own residence. Managing a company from abroad raises the separate question of where that company is tax resident, decided by effective management rather than by the registry.
- Withholding on your pay. Director remuneration paid to a non-resident is taxed under the non-resident rules, and the applicable treaty may limit the rate.
This is the configuration where the largest and most expensive mistakes happen, because two exposures are being managed at once — the founder's and the company's — and they are usually analysed separately when they interact.
What goes wrong.
- Registering late. The obligation arises when the activity starts, not when the first invoice is raised or the first salary is paid. Contributions are owed for the intervening period, with surcharges.
- Budgeting the ordinary autonomo figure. A founder plans around 200-odd euro a month, then meets the societario floor. In 2026 the gap is more than 240 euro a month.
- Assuming the reduced rate is unavailable. Guidance written before the Supreme Court settled the point is still widely republished, and following it costs about 4,400 euro in a first year.
- Relying on a management employment contract. Absorbed by the corporate relationship. It buys nothing and it is not a defence.
- Leaving the articles silent on remuneration. Recoverable through litigation, avoidable for nothing at incorporation.
- Forgetting the family aggregation. Shares distributed across a household to stay under a threshold generally reach it anyway.
- Expecting a safety net. No unemployment benefit and no wage guarantee fund. If the company fails, the founder is last in every queue, including their own.
The shareholding split is decided once, and it decides this for years.
Percentages set at incorporation determine the regime, the monthly cost, the availability of the reduced rate and the tax treatment of everything you draw. We model the combination before the deed is signed, which is the only point at which changing it is free.
