Brazil Tax Reform consolidates multiple indirect taxes into a dual VAT structure to simplify compliance and improve transparency. It affects calculation, reporting and processes, so early preparation supports smoother operations.
Brazil’s Tax Reform: Opportunities and Challenges for Businesses
Brazil’s tax system has long been recognised as one of the most complex in the world. Businesses operating in the country often find it difficult to stay compliant due to its fragmented structure, with a lack of harmonisation between jurisdictions leading to inconsistent interpretations and costly errors, especially when managing multiple indirect taxes in Brazil at once.
To address these challenges, Brazil has approved a landmark tax reform law, a major step in tax reform in Brazil aimed at simplifying the system, improving efficiency, and enhancing transparency.
While the new structure promises to reduce the administrative burden over the longer term, the transition period presents a significant challenge for businesses, requiring them to manage both systems simultaneously and adapt to how Brazil taxes consumption under legacy and new regimes.
To support businesses through this transition, Vertex offers a comprehensive solution with robust support for Brazil, powered by our industry-leading tax engine Vertex O Series. It is designed to help organisations stay compliant with indirect tax requirements in Brazil and reduce risk throughout the reform and beyond.
What’s Changing? The Brazil Tax Reform Explained
Brazil’s tax reform will be introduced gradually between 2026 and 2033, creating a clear timeline for planning and readiness. During this transition period, businesses will need to comply with both the legacy and new tax systems, making early preparation essential.
Until the end of 2025, Brazil’s tax system will remain divided across federal, state, and municipal levels, with overlapping taxes such as PIS, COFINS, ICMS, and others. However, from 1 January 2026, a simplified structure will be introduced alongside the existing system during the transition period:
- Federal level: CBS (Contribution on Goods and Services) will replace PIS and COFINS.
- State / municipal level: IBS (Tax on Goods and Services) will replace ICMS and ISS, beginning in 2027.
- Additional taxes: IS (Selective Taxes) will apply to specific goods, such as tobacco and alcohol, and IPI (Tax on Industrialised Products) will continue to apply in Free Trade Zones only.
CBS and IBS will function as value-added taxes (VAT) in Brazil, applied at each stage of the supply chain to improve transparency. Oversight will be centralised, with the federal government managing CBS and a national committee managing IBS.
