Paying tax on global wealth can be complicated. We take a proactive approach, helping you stay compliant and making sure you don’t pay more than you should. We provide clear guidance that adapts as circumstances and priorities evolve.

International wealth brings international tax challenges
Our dedicated experts can advise on bespoke international tax strategies and manage them on your behalf.
If you have assets and investments in different countries, your wealth is affected by a variety of different tax regimes, regulatory and cultural issues. Ex-pats, so called ‘non-doms’ living in the UK short or long term, and even UK individuals who simply have a holiday home or other assets elsewhere, can all be affected by cross-border tax complexity.
