Person responsible for the obligation to contribute
The contribution is to be paid by the subscriber to the special agreement. Natural or legal persons who voluntarily assume this obligation with the express authorisation of these workers may act as substitutes for the workers who sign the special agreement.
Contribution basis
The contribution basis will be the one chosen by the interested party from among those in force in the Special Scheme for Self-Employed Workers.
Determination of the payment due
The single contribution basis in force in the General Scheme shall be applied to the type of contribution chosen by the person concerned.
The result obtained shall be multiplied by the reduction coefficient set annually by the Contribution Order.
Likewise, from 1 January 2023, the additional payment corresponding to the Intergenerational Equity Mechanism is in force, which is determined by applying the corresponding rate each year to the contribution basis.
Payment deadline
The payment shall be made in the same month as the month to which the settlement applies.
Increase in the contribution basis of the agreement after the special agreement has been concluded
In general, the contribution basis will be increased by the same percentage as the increase in the minimum base of the Special Scheme for Self-Employed Workers.
However, the subscriber may choose to have the contribution basis of the agreement revalued in accordance with the annual increase in the maximum contribution base of the Special Scheme for Self-Employed Workers.
If this increase has not been chosen, it shall be increased in accordance with the previous paragraph.
The application for a voluntary increase in the contribution basis (or waiver of such an increase) can be made through any of the channels indicated for this purpose in the section: “Special Agreement Procedures and Arrangements
”. The deadline for applications is 30 September of each year, with effect from 1 January of the following year.
