Contribution gaps are considered to be those periods without contributions that fall within the range of months from which the regulatory base is determined. For workers who retire through the General Scheme, the 48 months without contributions closest to the qualifying event (retirement) will be integrated by the minimum base of all those existing at any given time, and the rest by 50% of that minimum base. In the Self-Employed Workers’ Scheme (RETA), there is no formula for integrating gaps, and they are computed as a zero base.
