Among the concepts that come up more and more often when discussing the sustainability of Spain's pension system is the Intergenerational Equity Mechanism (MEI), an additional contribution introduced in recent years whose purpose and workings are worth understanding.
What the MEI is and why it was created
It's an additional Social Security contribution, applied to the contribution base of workers and companies, specifically aimed at feeding a reserve fund designed to handle the financial impact on the pension system when the largest generations (the so-called baby boom generation) retire over the coming decades.
Why it's called "intergenerational equity"
The name reflects its logic: it aims to spread the cost of population aging more evenly across generations, avoiding a situation where the necessary adjustment falls exclusively on future generations at the moment when the largest wave of retirements happens, through an advance build-up of resources funded by today's workers.
Who pays this additional contribution
It's split between employer and employee, similarly to how other social security contributions are split, applied as an additional percentage on the contribution base for common contingencies, distinct and separate from the ordinary contributions that already existed before.
It's not a contribution that generates direct individual rights
Unlike other contributions that do directly affect the calculation of your future individual benefit (such as ordinary contributions, which determine your regulatory base), the MEI contribution doesn't directly increase the amount of your future personal pension: its function is to feed a collective reserve fund for the system, not to generate a proportional individual right for whoever pays it.
Until when it's expected to apply
It was established for a set period of time, expected to apply over several years (with the possibility of review and adjustment of the applicable percentage during that period), as part of the broader set of pension system reform measures aimed at ensuring its sustainability in the medium and long term.
Why it sparks debate
Like any measure that raises the cost of contributions without generating a direct proportional individual right, the MEI has been the subject of debate among different social and economic actors, with divided views on whether it will really be sufficient to cover the expected financial impact and on its effect on the labor costs of companies and workers.
