Contribution bases for 2025
The social security contribution system for the self-employed is based on annual net income. Self-employed individuals must provide the Social Security Administration with a forecast of the net income they expect to obtain from all their economic activities. Net income is calculated by deducting all necessary expenses from total income, as well as a 7% deduction for general expenses (3% for self-employed individuals who are also company directors).
Throughout the year, self-employed workers can modify their contribution base up to six times to adjust it to changes in their projected income. Based on the income forecast they have submitted, they must choose a contribution base between the minimum and maximum contribution bases corresponding to their income bracket, according to the general table of contribution bases.
In any case, the chosen bases will be provisional until they are regularized from the following year onwards, based on the annual income obtained and reported by the Tax Office.
Once the final contribution base has been calculated, if it is higher than the base on which the self-employed worker has been contributing provisionally during the year, the affected party may pay the contribution differences, without late payment interest or any surcharge, until the last day of the month following the month in which they are notified of the result of the adjustment. If their provisional base is higher than the final base, they will receive a refund for the excess contributions paid.
For the purpose of choosing the contribution base, the General State Budget Law will establish tables each year with different income brackets for the self-employed; in addition, a minimum and a maximum contribution base will be established for each bracket. Thus, the self-employed worker must choose a contribution base that falls between the minimum and maximum set for the income bracket they expect to earn during the year.
The table for the year 2025 is as follows:

The total contribution rate is 30.60% (plus 0.80% of the MEI), broken down into the following items:
| Concept | Percentage |
|---|---|
| Common contingencies | 28.30% |
| Professional contingencies | 1.30% |
| Cese de actividad | 0,90% |
| Formación profesional | 0,10% |
| Total quotation rate | 30.60% |
*Where applicable, the 0.80% corresponding to the MEI (Intergenerational Equity Mechanism) must be added.
