Franco-American taxation

Our expertise for your strategic operations

Companies and investors that have business relations between France and the USA are exposed to separate national rules, which can be hard to articulate together. The U.S.-France income tax treaty has very specific solutions that must be mastered by true specialists. The same applies to the reporting obligations arising from the FATCA system.

Complexity and international compliance

We support our clients with their international fiscal and estate management, optimising and securing a change of tax residency, the taxation of expatriates and foreign sources of income, or even transatlantic inheritance. Our teams also offer assistance with tax audits or adjustments.  

International teams

Our teams guide company directors and groups in how to structure their transatlantic operations to ensure that American, French and European rules are adhered to.
