Boutique tax firm specialized in international tax law
Focusing on complex international situations
Our practice focuses on complex international situations involving multiple jurisdictions, including tax residency issues, cross-border investment structures, holding and ownership planning, and the coordination of tax exposure across different legal systems.
Our approach is pragmatic, discreet and highly personalized, with a strong focus on legal certainty, tax efficiency and long-term sustainability in an international context.
We regularly advize clients with ties to Brazil, France, and the United States, and assist them in navigating the interaction between domestic tax rules and international tax treaties.
From strategic tax advice to the design and implementation of tailored legal and tax structures, taking into account income tax, wealth tax and succession-related tax aspects where relevant.
We are experienced in situation involving US citizens and I provide solutions to mitigate the double taxation issues.
We also have a special knowledge of the conventions with Brazil (social security and tax treaty) and can assist with taylor-made propositions.
We work fluently in French, English, and Portuguese, with conversational Russian.
