Tax

Denton’s Luxembourg team has advised clients from major industry sectors in all key business areas. The team is expansive and handles major cross-border transactions, litigation and structuring. In Luxembourg, the practice has tax compliance and reporting faculties. Partner Jean-Luc Fisch is supported by senior counsel Romain Baroan and counsel Vincent Quittre.

Recent highlights include advice to Adepa, an independent fund administrator, in relation to its alliance with Banco Inversis. It also provided a special purpose vehicle for the Islamic Development Bank in a lucrative transaction.

Practitioner Lars Weineck joined the firm as head of anti-money laundering during the research period, with associates Alexandre Michorzic and Yifei Li also coming on board.

Client feedback

“Highly professional, short reaction times, in-depth know-how, very organised with a plan broken down into more than a dozen steps, very easy to work with, worth every cent we paid.”

“Very professional and collaborative.”
