Brazil's Tax Reform Impacts Retail, Banking, Energy and Transport Sectors

Brazil's tax reform, enacted by Constitutional Amendment 132/2023, replaces ICMS, ISS, PIS and Cofins with the consumption taxes IBS (Imposto sobre Bens e Serviços) and CBS (Contribuição sobre Bens e Serviços). The transition runs until 2033, with mandatory invoice adaptation starting in 2026 and split‑payment mechanisms required from 2027.

Retailers in Minas Gerais are preparing for the new split‑payment system, which will automatically deduct tax at the point of sale and affect cash flow, pricing and inventory. The banking sector has secured a judicial ruling from the Superior Tribunal de Justiça (STJ) that discounts on bank fees are considered unconditional, meaning ISS will be calculated only on the amount actually paid by customers, reducing tax liabilities.

Small and medium‑sized enterprises in the electricity sector face a complex transition, needing new accounting systems, technology upgrades and liquidity management to handle the shift to IBS and CBS while maintaining competitiveness. The STJ also created a new “Conflito Federativo” procedural class to resolve disputes between states, municipalities, the Union and the IBS Management Committee, clarifying governance during the transition.

In the logistics and transport industry, executives warn that the reform is not merely an accountant's issue but a business leadership challenge. As one transport executive stated, “A reforma tributária não é um tema do contador, é um tema do empresário.” The sector must also adapt to AI tools, new regulatory identifiers (CIOT) and heightened complexity, prompting calls for staff development and anticipating consolidation through mergers and acquisitions.
