Claudia Lanzoni, Tax Manager at SMP Accounting and Tax, has become the first person to complete the Advanced Diploma in International Taxation (ADIT) in the Isle of Man.

She had to pass three examinations to achieve the Chartered Institute of Taxation qualification, with subjects covering principles of international taxation, transfer pricing, OECD double tax treaties and OECD initiatives in the tax field, UK taxation of cross-border transactions, UK taxation of mobile individuals, UK non-domiciled and offshore trusts, EU law and CJEU tax cases.

Claudia’s first language is Italian, meaning she had to study complex tax matters and sit demanding exams in her second language, making her achievement remarkable.

ADIT is a specialist, advanced qualification in international and cross-border taxation which provides the opportunity to prove and improve professional credentials in international tax. It is recognised as a global benchmark of quality and an independent way of demonstrating knowledge and ability.

Claudia, who joined SMP in 2006, said: ‘I am extremely proud to have achieved this qualification, which is the result of intensive studying, hard work and the support of everyone in the SMP Partners Group.

‘The additional knowledge earned during this process will further enhance the professional service SMP Accounting and Tax delivers for our clients all over the world.’

Since joining SMP Accounting and Tax in 2012, Claudia has assisted with queries on UK and international taxation, as well as the preparation of UK tax returns for companies, individuals and trusts.
