Our Tax Litigation practice manages over 6,000 judicial and administrative cases across Brazil, combining legal strategy, procedural management and data intelligence to deliver efficient and high-impact results. With more than two decades of experience, we are recognised for developing strategies that prioritise strong evidence at the administrative level, reducing the need for lengthy judicial proceedings.
The team is structured into specialised units covering federal, state, municipal and social security matters, as well as a group dedicated to identifying and recovering unduly paid tax credits. All activities follow strict governance and data protection standards, supported by access-controlled systems and real-time BI dashboards for managers and clients.
We act for major companies in sectors such as telecommunications, energy, mining, infrastructure, oil and gas, logistics, agribusiness and retail. Recent work includes a BRL 500 million credit recovery case for an agribusiness leader, a landmark ICMS dispute for a telecom operator, and the defence of a logistics company against undue ISS charges.
Our mix of technical excellence, innovation and sector insight positions us as a reference in complex tax disputes and credit recovery across Brazil.
