Spanish civil servant going freelance: the price means giving up allowances

Civil servant and freelancer: the price of holding two jobs

A civil servant with a permanent post and full-time dedication wants to start their own business. The problem is not the law: it's the arithmetic. Combining the post with private activity means giving up allowances and productivity bonuses, and net pay plummets. The calculation this public employee is working with points to a drop of up to 400 euros a month. Requesting permission, moreover, means first reducing the specific allowance (complemento específico, a variable pay component) and waiting months to receive, in all likelihood, a no.

The sole-shareholder alternative isn't convincing either. A limited company with 100% of the capital and no staff ends up with the tax agency (AEAT) and Social Security pointing at the only person who actually works there: the civil servant themselves. The family front-man figure falls apart when the partner also holds a public post. And registering as self-employed without declaring it is a serious offence that only works as long as nobody cross-checks the data.

What registering as self-employed really costs

The debate over compatibility runs into a reality many discover too late: being registered in the self-employed scheme is not free even if you already pay contributions through an employer. Contributions must be paid all the same. Someone who has combined a full-time job with a weekend activity sums it up in a frightening figure. There is no exemption for double contributions.

Some propose an intermediate way out: registering as self-employed while keeping the salaried job, on the idea that the income from the main job improves when the new activity is added. On paper it sounds good. In practice, the system does not reward the dual status; the sum of contributions and tax obligations eats up much of the margin.

The limited company as a tax shelter: why it doesn't wash

The corporate structure is the route most explored and the one dismantled fastest. Setting up a limited company (SL) with 100% ownership and no employees does not hide the reality: the person who invoices, decides and executes is the same one paid by the Administration. Data cross-checks between AEAT and Social Security don't need shared surnames to detect a concealed economic activity.

The straw-man solution —a trusted third party with no apparent ties— is proposed as the only clean path. It's also suggested that a nephew-in-law or a brother-in-law would be enough to dodge the tracking. It's a risky bet: if the business contracts with the Administration or is related to the duties of the post, the matter stops being an administrative offence.

Leave of absence, passive income or coaching exam candidates: the real way out

The most cited and least segarro route is the leave of absence (excedencia). It allows registering as self-employed without restrictions, with the safety net of being able to return, though not before two years except in childcare or family care cases. For those unwilling to give up their post, passive income and preparing candidates for civil service exams remain.

The underlying diagnosis is uncomfortable: full-time dedication is designed so that public employees do not compete with the private sector. Those who want to do both run into a system that forces them to pick a side. The question is how many are willing to give up a fixed salary to try.
