Jean-Luc Bouton is a partner at Ascott Associes, a business law firm based in the heart of Paris that advises a demanding French and international clientele. Working from the firm's offices at 22 rue Jean Mermoz in the city's eighth arrondissement, he focuses on international tax, one of the most technically exacting areas of modern legal and financial advice.

A Paris business law firm with international reach

Ascott Associes describes itself as a firm dedicated to delivering high-quality services to an exacting French and foreign clientele, and its practice spans corporate law, business law, real estate, tax, employment and litigation. That breadth allows the firm to support companies and entrepreneurs across the full life cycle of their activities, from structuring and day-to-day operations through to disputes. The firm coordinates with specialist partners such as accountants, auditors, notaries and banks, and represents clients before the administrative and regulatory authorities, so that complex matters can be handled in a joined-up way. Within this full-service platform, Jean-Luc Bouton's international tax expertise is a natural complement to the firm's corporate and cross-border work.

International tax at the centre of cross-border business

International tax is the discipline that governs how income, gains and transactions are taxed when they cross national borders. It draws on domestic tax codes, bilateral tax treaties and the evolving body of international standards, and it bears directly on how multinational groups, investors and individuals structure their affairs. For a French firm advising foreign clients and French clients operating abroad, the ability to give clear, reliable international tax advice is essential. Ascott Associes maintains relationships with foreign counsel across the United States, the United Kingdom, Hong Kong, Spain, North Africa and Central and Eastern Europe, and its multilingual team is equipped to work in English alongside French, which positions the firm well to handle matters that reach beyond France.

International tax work of the kind carried out at this level typically involves:

• Advising on the tax structuring of cross-border investments and operations
• Applying double tax treaties to avoid or relieve double taxation
• Guiding internationally mobile individuals and businesses on their French tax obligations
• Coordinating tax advice with corporate, real estate and employment matters
• Representing clients in dealings with the tax and regulatory authorities

Integrated, client-focused advice

What distinguishes Ascott Associes is its emphasis on personalised handling of each matter and its willingness to coordinate with the other professionals a client relies upon. In international tax, where a single transaction can raise corporate, financial and regulatory questions simultaneously, this integrated approach is particularly valuable. Clients benefit from advice that is not delivered in isolation but is joined up with the wider legal and commercial picture, helping them to pursue their objectives while remaining compliant across the jurisdictions in which they operate.

Recognition in a demanding field

International tax rewards precision and experience, and recognition in this area reflects a practitioner's ability to guide clients confidently through some of the most intricate questions in modern law. For a partner at a Paris firm advising an international clientele, an award of this kind acknowledges not only technical mastery but also the trust that clients and peers place in the quality and reliability of the advice. As tax authorities around the world coordinate more closely and cross-border transactions face growing scrutiny, the value of a steady, well-informed adviser continues to rise. Clients turn to specialists who can anticipate difficulties, structure arrangements soundly and stand alongside them in dealings with the authorities, and it is on this foundation of dependable, expert counsel that a reputation in international tax is built.

For French and international clients seeking dependable guidance on cross-border tax, Jean-Luc Bouton and Ascott Associes offer the combination of technical depth, an international network and a full-service Paris platform. His recognition as International Tax Lawyer of the Year in France at the Corporate INTL Global Awards 2026 confirms his standing as a leading practitioner in this specialised and demanding field.
