US Tax Services

The challenge

Multinational companies often have significant US tax implications. Either through a significant presence of non-US individuals working in the US or significant volumes of US citizens working or employed in Switzerland. US tax legislation creates unique and ongoing implications for compliance and costs,  and understanding these is a constant challenge.

Our team is uniquely placed to handle the  US tax  position of individuals – whether they are full US tax payers or resident outside the US but with business, investment, family or other personal connections to the US. 

As well as assisting clients with US expatriates on foreign assignment, we have extensive experience in dealing with entrepreneurs, partners and associates of law firms and many senior executives based in Switzerland. We are fully integrated with our Swiss PCS group to ensure holistic advice is provided on both Swiss and US implications.
