In 2023, a reform was launched that overhauled the social security contribution system for the self-employed (RETA). This modification was based on the report of the Toledo Pact commission. The reasons were clear: the average RETA pension was significantly lower than that of the general system—37.4% lower in Catalonia in 2020—and there was a high dependence on minimum supplements (34% in the RETA, compared to 20% in the general system). All of this occurred within a model that allowed workers to freely choose their contribution base, leading more than 80% of the self-employed to contribute at the minimum rate. The 2023 reform introduced a profound conceptual change: contributions would be adjusted according to business results. The objective was threefold: to improve benefits, reduce the need for supplements, and increase Social Security revenue. The transformation was planned over nine years, with an initial phase (2023-2025) focused on testing the new model.
