Seguridad Social
The Seguridad Social is Spain's social security system. It is a public system funded primarily through contributions from employers, employees, and self employed workers. It provides healthcare through the Sistema Nacional de Salud, retirement and disability pensions through the INSS, unemployment benefits, maternity and paternity leave, and other family protections. Nearly every resident in Spain interacts with it in some form.
How it is structured
The system has two main operational arms. The TGSS (Tesorería General de la Seguridad Social) handles the financial side: collecting contributions, managing registrations, and issuing NUSS numbers. The INSS (Instituto Nacional de la Seguridad Social) handles the benefits side: assessing entitlements and paying out pensions, sick leave, and other benefits. Together, they form the complete cycle of contributions in and benefits out.
Who is covered
Employees are automatically covered. Their employer registers them with the TGSS and both parties make monthly contributions. Self employed autónomos register themselves and pay a monthly cuota based on their declared income. Pensioners arriving with an S1 form from another EU country are covered through bilateral agreements. Family members can be covered as dependents (beneficiarios) under the main contributor's registration. People who do not fit any of these categories can access healthcare through the Convenio Especial or private insurance.
What it costs
For employees, the contribution is split between employer and employee. The employee's share is approximately 6.35% of gross salary, while the employer pays approximately 30%. For autónomos, the monthly cuota depends on declared income, with a minimum of approximately 225 euro and a maximum of approximately 530 euro per month in 2026. Pensioners with an S1 form pay a woonlandbijdrage (country of residence contribution) to their home country, not to Spain directly.
