Tax law | in Switzerland and in France, domestic and international contexts

Tax

We are among the few law firms with experienced tax teams in both Geneva and Paris, providing advisory and support services to clients in domestic and international matters.

Our lawyers and tax specialists combine deep expertise in the Swiss and French tax systems with practical experience in handling both domestic and cross-border issues in a constantly evolving economic environment. To best serve our clients, we consistently integrate the international dimension into our approach, paying close attention to the interplay between national legislation and the impact of bilateral or multilateral tax treaties, tax assistance, and information exchange.

The growing complexity of cross-border situations can create legal uncertainty, such as the risk of double taxation, but also offers opportunities for tax planning and structuring. Our teams provide guidance and support to help you identify and implement the solution that best suits your specific needs.
