Our location in Switzerland means that we are the first port of call for many Swiss based asset managers, financial institutions, and trustees, who may have UK connected clients or face UK tax issues. We regularly advise clients on the tax implications of moving to and from the UK, or the acquisition of property in the UK whether that be through a structure or in personal name. We also advise on the remittance basis of taxation for non-domiciliaries. UK tax disclosures for private clients can also be handled by our team in Switzerland.
