The social security portal makes it clear that in cases of multiple activities, the professional must contribute to both regimes, that is, to the public regime, when employed by another person; and in the Special Regime for Independent Workers (RETA) when they do it on their own. In this case, the worker will calculate the advantage of being able to withdraw the coverage to which he already contributes as an employee as a self-employed person.
Thus, the professional is entitled to a refund of 50% of the excess offered, subject to fees paid for contingencies common to both systems.
