Profile
Services
Jonathan is a partner in the firm’s private wealth team. He advises both UK residents and international clients on UK tax, trusts, estate and succession issues with a particular focus on international cross-border matters for non-UK domiciled clients (resident in the UK or elsewhere), offshore trustees and family offices.
This includes advising on residence, domicile, the remittance basis of taxation, and developing or refining structures and strategies to preserve wealth and avoid unnecessary tax and succession implications.
Jonathan regularly advises individuals moving to or from the UK on how to plan their affairs in a tax efficient manner before they arrive or depart. Often this will include considering the impact on, and planning for, any business they own or structure they can benefit from.
He is experienced in advising entrepreneurs at all stages in the lifecycle of their business. For example, an efficient will, personal tax strategies around sale, or how to manage the succession of the business down to the next generation of the family.
Jonathan has built up experience on the cross border tax, legal and compliance issues between South Africa and the UK, and has travelled there often.
He is a member of the Society of Trust and Estate Practitioners (STEP) and has obtained the STEP Diploma and the STEP Advanced Certificate in UK Tax for International Clients and a STEP excellence award. Jonathan is named as a key lawyer in the leading legal directory Legal 500, and is ranked in Chambers in the High Net Worth Guide and as a lawyer with foreign expertise in South Africa. Also, he is included in the top 100 Crypto Advisers and managers curated by Citywealth as highly accredited.
Jonathan is a member of the Tax Law Committee of the Law Society which engages with HMRC on policy and new legislation.
