Jonathan Colclough

Spear’s Review

Jonathan Colclough is a partner at Mills & Reeve and the head of the firm’s Africa desk. He advises UK and international clients on tax, trust and succession planning, with a particular focus on those with an African – and specifically South African – nexus. 

‘I’m basically a funnel,’ Colclough explains. ‘If there are any inquiries that have an Africa need’, he will reach out to firms ‘in various countries in Africa to see if they can help’. 

Colclough often works with business owners, helping entrepreneurs at ‘all stages in the life cycle of their business’. He also advises on onshore and offshore structures, drawing together tax, investment and estate planning that often involves the UK, Jersey and Guernsey. 

Adviser Profile

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.

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 also accredited with advising on how crypto is taxed and what structures might be relevant for tax and other purposes. 

He is a member of STEP and has obtained both the STEP diploma and the STEP advanced certificate in UK tax for international clients and STEP excellence award.
