An important aspect of our tax practice is the presence of tax teams in nearly every branch of the firm, ensuring precise and timely legal services regardless of where clients’ transactions take place. This nationwide structure represents a major competitive advantage over other full-service firms.

Current work includes: Advising a French multinational IT and consulting group with operations in Brazil and Spain on the taxation of service imports. The team issued a comprehensive legal opinion covering Brazilian tax rules, the application of double taxation treaties, potential exposure to privileged regimes, as well as assessing the impact of Brazil’s new OECD-aligned transfer pricing rules to ensure compliance, mitigate tax risks, and optimize the client’s global contracting model.
