When I first arrived in Spain, I was completely baffled by the social security system, especially the amount deducted from my payslip each month. I always wanted to understand how it was calculated. I’ve recently done some research and compiled the latest 2024 contribution rates into a table to share with everyone. I hope this helps others who might have the same questions.

Contribution Bases for the Self-Employed and Employees
First, you need to understand the concept of the ‘contribution base’ (base de cotización). Simply put, this is the basis for calculating your social security contributions, not your entire salary. Each year, the government sets minimum and maximum limits for this base. For 2024, the minimum is €1,260/month, and the maximum is €4,720.50/month. Your specific contribution base falls within this range and depends on your professional category and salary level.
Contribution Percentages for Different Situations
Whether you’re self-employed or work for a company, the bulk of your contributions covers common contingencies, including the public healthcare we’re most concerned about. It also covers unemployment, professional training, and work-related accidents. For regular employees, the company pays most of it, and we only need to cover a small portion, which is a pretty good deal.
The table below clearly lists the respective contribution percentages for employees and the self-employed. You can check it against your payslip. For specific agreements, it’s also worth looking into the Convenio Especial:
| Item | Paid by Company | Paid by Employee | Self-Employed |
| Common Contingencies | 23.60% | 4.70% | 28.30% |
| Unemployment | 5.50% | 1.55% | Not Applicable |
| Professional Training | 0.60% | 0.10% | Not Applicable |
| Work Accidents & Occupational Diseases | Variable Rate | 0% | 1.30% |
| Total | Approx. 31% | 6.35% | Approx. 31.20% |
It is important to note that the contribution system for the self-employed is now tied to their actual income, which is more complex than before, though the basic principle remains. The data in the table serves as a general guide. For those in specific industries, other regulations may also be relevant, such as those concerning Spain medical device certification. In summary, as long as you are legally working and contributing to social security, you are entitled to Spain’s public healthcare services. Consultations with a family doctor, examinations at public hospitals, and even surgeries are generally free of charge, with you only needing to cover a portion of prescription medication costs. We hope this post is helpful! If you have any questions, feel free to join the discussion.
