The Brazilian Superintendence of Private Insurance (SUSEP), together with the Special Secretariat of the Federal Revenue of Brazil (RFB) and the National Superintendence of Complementary Pensions (Previc), issued joint rules establishing procedures for portability of resources and for the transfer of participants and their reserves between pension-type benefit plans. The framework applies to both open and closed complementary pension arrangements and is aligned with Article 22-A of RFB Instruction No. 2,209/2024 and Law No. 14,803/2024. Under Joint Normative Instruction RFB/PREVIC/SUSEP No. 01/2025, the transferring entity must provide the receiving entity, when making portability information available, with information on accumulation periods in the original plan in all cases of portability. Previously, this information was provided only where the participant had chosen the regressive tax regime; the requirement has been expanded because Law No. 14,803/2024 moved the choice between progressive and regressive taxation from the time of enrolment to the time the participant requests benefits or redeems accumulated balances.
