Social Security and Pensions in Spain: What Employers Fund

Spanish social security, the Seguridad Social, is a broad public system. The contributions from employer and employee together fund public healthcare, the contributory state pension, unemployment benefit, sick pay after the employer’s initial period, parental and family leave, and support for workplace accidents. It is why the deductions are larger than income tax alone in many cases.

On a standard permanent contract in 2026, the employer pays around 30.65% of salary and the employee about 6.5%. The mechanics of those rates are covered in our guide to Spanish payroll; this article is about what they pay for.

The centrepiece is the contributory state pension. In 2026 the ordinary retirement age is 66 years and 10 months for people with fewer than 38 years and 3 months of contributions, while those who have contributed 38 years and 3 months or more can still retire at 65. This is the last step of a long transition toward a standard age of 67.

To qualify for a contributory pension at all, a worker needs at least 15 years of contributions, with two of those years falling in the 15 years before retirement. The amount is based on the contribution history over a long reference period, currently the last 25 years, with a phased reform beginning in 2026 that will eventually let retirees choose a more favourable calculation.

Because Spain’s population is ageing, the government introduced the Intergenerational Equity Mechanism, the MEI, to shore up the pension system. It is a small extra contribution on top of the normal rates: for 2026 it is 0.90% of the contribution base in total, split 0.75% on the employer and 0.15% on the employee. It rises gradually over the coming years.

For an employer, the MEI is simply another line in the social security cost, but it is worth knowing what it is when it appears on the breakdown. It is the system’s way of pre-funding future pensions rather than a charge specific to your business.

Alongside the state pension, Spain has been actively encouraging a second pillar: employment, or occupational, pension plans (planes de pensiones de empleo), where the employer is the promoter and employees are the participants. Historically these have been less common in Spain than in some countries, and recent policy has aimed to grow them, including simplified collective plans for smaller firms.

For most employers these remain optional, a benefit rather than a legal requirement, though some sectors introduce them through the collective agreement. If you want to offer a competitive package in Spain, an occupational plan is one of the levers, and it can be set up as part of the wider employment arrangement.

The practical takeaway is simple. Your mandatory obligation is the standard social security contribution, which funds the state pension and the wider safety net. Occupational pension plans are an optional extra you can choose to offer. And the employee’s future pension depends on their contributions being paid correctly and on time, month after month.

That last point is where getting payroll right really matters. Every correctly filed contribution counts toward the employee’s pension and benefits, which is one more reason compliant employment beats an informal arrangement. An EOR service in Spain makes sure those contributions are calculated and paid properly throughout the employment.
