Fully versed in all expatriate tax issues such as social security planning, non-dom planning he has enhanced the established expatriate tax team. In 2018, Fiona Mitchell became our Senior Expatriate Tax Manager and will expand our capacity to handle specialist expatriate enquiries.  In particular our assignment planning services are seeing strong growth and she will be invaluable in enabling those services.

With this expansion we have also grown a network of international partners enabling us to provide an holistic advisory service to clients who have interests in multiple countries.
