James Quarmby
Spear’s Review
James Quarmby, head of private wealth at Stephenson Harwood, has always been a cerebral and outspoken practitioner in the field. He remains dauntless in defending HNWs and diligently helping his clients navigate the UK’s tax landscape.
One peer commends his technical excellence, ‘which shines through’, noting his ability to ‘dissect difficult subjects into a more comprehensible format’.
Quarmby’s practice is decidedly international – he works with the firm’s offices in Singapore, Paris, Hong Kong and Dubai – and covers a wide-ranging brief across taxation, residency and domicile matters.
He is one of the most prominent tax lawyers in the UK and a frequent face in the media, including a famous defence of David Cameron’s offshore funds in a live argument with John Humphrys.
