Overview

Grant Thornton Austria’s tax team, led by Raphael Holzinger and Werner Leiter, comprises over 150 professionals advising a wide range of clients—from sole proprietors to listed companies. With 2024 tax revenues exceeding €17.5 million, it ranks among Austria’s top tax teams. The firm offers partner-led, personalised tax advisory and compliance services, leveraging its international network and cross-border collaboration to support clients expanding globally. 

During the research period, the firm provided buy-side structuring advice and post-deal integration support for the acquisition of a large software provider, navigating multiple complex restructuring steps. In addition, the team assisted a legal tech client for cross-country tax and transfer pricing restructuring, recognising the firm’s reputation as a leading advisor in complex international tax matters.
