Mattos Filho

Mattos Filho‘s government relations practice plays an active role in legislative discussions within the National Congress, offering strategic recommendations and advocating for corporate interests on critical matters—most recently, the tax reform and the regulation of ride-sharing services in Brazil. The team’s high-level engagement is supported by a multidisciplinary approach that draws on expertise in tax, M&A, ESG, financial markets, labour law, compliance, and corporate ethics. This broad-based knowledge enables the practice to advise a diverse client base, including prominent players in agribusiness, biotechnology, renewable energy, finance, infrastructure, and the non-profit sector. The practice is led by tax litigation and government relations specialist Ariane Costa Guimaraes.
