Around 1.2 million self employed workers in Spain are facing a noticeable rise in their social security contributions, with some set to pay €135 more per month from 2026. The change mainly affects family collaborators and company linked autónomos, and while the higher amounts may not be collected immediately, they will still be calculated and could be due later, likely from 2027 or 2028.

For many, the concern is not just the increase itself, but how it is being applied. The adjustment comes from a rise in the minimum contribution base, which will move certain groups into higher payment brackets regardless of what they actually earn.

Why some autónomos will pay more even if they earn less

At the heart of the issue is how the contribution system works. Spain has been moving towards a model where payments are linked to real income. However, in this case, some self employed workers are being pushed into higher levels automatically, without that income link being fully reflected.

This means that certain autónomos will effectively skip several contribution bands compared to others. For those affected, the extra cost is far from symbolic. Estimates suggest an increase of between €869 and €1,606 per year, depending on the situation.

The problem becomes even more visible in family businesses. In some cases, a collaborating spouse may end up contributing more than the main self employed worker, even if their role or income is smaller. It is this kind of scenario that has fuelled frustration among professionals and associations.

Many see it as a mismatch between the idea of a fair system and what is happening in practice.

Government says the change was already planned

The Ministry of Social Security has defended the measure, insisting that it is not a new decision but the result of applying legislation approved in 2022. According to the government, that law already set out that by 2026, certain categories of self employed workers would align their contribution base with the minimum level used in the general system.

From that point of view, the increase is simply the next step in a reform that was agreed several years ago. The aim, officials say, is to improve protection for the self employed and bring their contributions closer to those of salaried workers.

However, this explanation has not settled the debate. Representatives of the self employed argue that the same law also required a review of the system before applying such changes. They say that review has not happened, and that the increase is being introduced without taking into account how it affects people on the ground.

The issue has now reached the political stage, with several parties looking at ways to challenge or amend the measure.

Growing concern among older and rural workers

Beyond the technical details, there is a wider concern about who will feel the impact most. According to organisations representing the self employed, a large share of those affected are women, many over the age of 50 and working in smaller or rural businesses.

For these workers, an extra €135 per month is not a small adjustment. It can directly affect the viability of their activity, especially in sectors where income is irregular or margins are already tight.

There is also frustration about the lack of flexibility. The system does not always reflect the reality of how small businesses operate, particularly when roles within a family business are not equal.

This has led to criticism that the current approach risks creating situations that feel inconsistent, rather than fair.

What self employed workers should expect next

For now, the increase forms part of the current framework, even if the actual payments may be delayed. That means affected autónomos will need to factor these higher contributions into their financial planning, sooner rather than later.

Understanding your category within the system will be key. Not all self employed workers will be affected in the same way, and the exact impact depends on how your activity is classified.

Many are also waiting to see whether the political pressure will lead to changes or adjustments before the measure is fully implemented. Until then, uncertainty remains.

What is clear is that for a large number of self employed workers in Spain, costs are set to rise. At a time when many are already balancing fluctuating income and increasing expenses, this change adds another layer to manage.

For anyone working as an autónomo, it is a reminder that staying informed about how the system evolves is just as important as keeping track of your own business.
