Overview
- The Supreme Federal Court reached a 6‑to‑4 majority on Aug. 27, 2026 in favor of permitting IRPJ and CSLL to be charged on profits attributed to Brazilian parent companies from their foreign subsidiaries.
- Ministers Gilmar Mendes, Alexandre de Moraes, Flávio Dino, Cármen Lúcia, Cristiano Zanin and Kassio Nunes Marques formed the majority while rapporteur André Mendonça and Luiz Fux held the opposing view that the matter is infraconstitutional and belongs to the STJ.
- The case arises from a União appeal against an STJ ruling that protected Vale’s subsidiaries in Belgium, Denmark and Luxembourg from Brazilian tax, and the dispute centers on how article 74 of MP 2158‑35/2001 attributes foreign profits to domestic parents.
- Official estimates cited in the proceedings put the fiscal stakes in the billions: the 2026 Budget Guidelines Law (LDO) cites about R$22 billion for the immediate case and a 2023 Receita Federal note estimated R$142.5 billion for 2017–2021 plus roughly R$28.5 billion per year thereafter.
- With the plenary still open, the final outcome now rests on the vote of STF President Edson Fachin and the ruling could reshape tax certainty for multinationals, change tax audits and refunds, and alter federal revenue forecasts.
