Schellenberg Wittmer has promoted Regula Portmann to counsel in its taxation group in Zurich. Portmann joined the firm in 2008 as an associate.

She has experience in all aspects of tax law, particularly in corporate tax law and VAT. Portmann advises national and international clients on general questions of the Swiss tax law and has special knowledge in M&A transactions, restructurings, corporate immigration, real estate transactions and business aircraft structures. In addition, she represents clients before the public authorities and courts, in particular in contentious proceedings.
