Expertise since 2003

The firm was founded in 2003 by Su Na, who brought her experience as Head of Finance at an international tourism company into her independent advisory practice. Since then, the firm has grown steadily and is now one of the largest Chinese-speaking tax advisory firms in Austria, supported by a highly qualified team.

A longstanding focus has been the advisory of clients in the gastronomy and retail sectors. With the addition of Mag. Zhu Lei, the firm has further expanded its expertise, particularly in international tax law and corporate restructuring.

SuNa & LZh thus continues its development—true to its guiding principle: Together. Better.
