MEI 2026: changes in contributions and how they impact costs
The MEI in 2026 has become one of the elements shaping contributions this year.
In fact, one of the most common questions is how much the MEI is in 2026 and how it is applied to contributions.
Beyond the percentage, this mechanism is part of a set of adjustments that are redefining how labor costs are configured in companies.
What the MEI is in contributions
The MEI (Intergenerational Equity Mechanism) is an additional contribution applied to the base for common contingencies. It was created in 2023 so that the State could offset the increase in financial needs arising from the “Baby Boom” generation’s access to retirement benefits.
Unlike other mechanisms in the system, it does not generate increases in future benefits; it increases the cost associated with employment.
In practice, the MEI is incorporated as a percentage added to the rest of the contribution items within Social Security.
How much the MEI is in 2026
In 2026, the MEI stands at 0.90%, split between employer and worker:
Employer: 0.75%
Worker: 0.15%
To understand this figure, it is worth comparing it with the previous year. In 2025, the MEI was 0.80%:
Employer: 0.67%
Worker: 0.13%
This increase of 0.10 percentage points represents a direct rise in contributions, automatically incorporated into labor costs.
How the MEI works in contributions
The MEI is applied to the base for common contingencies and is incorporated into the usual calculation of contributions. This means that it:
is applied recurrently in each payroll
forms part of the monthly labor cost
and is added to the rest of the social security contributions
For this reason, its real impact is not analyzed in isolation, but within the whole.
Other changes to contributions in 2026
The MEI adds to other adjustments that are also having an impact on contributions:
The update of the maximum contribution base
The additional solidarity levy, applied to salaries that exceed certain brackets
These changes broaden the contribution framework and add new variables to the calculation of labor costs.
What companies are taking into account
What we are seeing in practice is that many companies are reviewing how these changes affect their contributions.
The interest lies not only in knowing how much the MEI is, but in understanding how it fits within the whole and what it implies for the cost structure.
That is where the analysis stops being theoretical and becomes operational.
At Fiabilis, we have spent years analyzing contributions from the inside, working with companies that need to understand how these changes really impact their day-to-day operations.
The MEI, the maximum base, and the solidarity levy are not isolated elements: they are part of a structure that, when properly analyzed, makes it possible to make well-informed decisions.
