Taxes are everywhere. Year in, year out, many of our clients successfully obtain favorable tax rulings, avoid risks and litigation and optimize their tax situation based on our advice.

The tax matters of our clients is our passion

We provide comprehensive services in tax matters for companies, entrepreneurs, managers and private individuals. Our advice is solution oriented, innovative, legally sound and effective. In many cases, the members of our tax group are co-operating with other professionals within our firm, in particular with colleagues in the Commercial, Corporate and M&A areas.

All our clients do have to pay taxes and we make sure that they do it in an optimized manner within the boundaries of the ever-changing legal framework.

While we strive to provide practical advice in our day-to-day work with our clients, we also have strong academic ties to Swiss tax law and our tax group members have a longstanding track record of publications and teaching in tax law.

Swiss tax law, whether purely local or with international elements, is our focus. For cross-border and international tax matters, we can count on our network of diligently chosen foreign tax experts.
