Why do ADIT?

Today's international tax professional will have a varied background, and the expectation that he or she will be increasingly mobile with an understanding of more than one taxation system.

ADIT, developed and supervised by leading international tax practitioners and academics, meets the needs of international tax practitioners working in the corporate arena.

It is a challenging and rigorous qualification but will reward you, your career, and your employer.

Authoritative technical knowledge

The ADIT qualification was developed and is supervised by an Academic Board consisting of several prominent international tax practitioners and scholars: Prof John Avery Jones, Dr Philip Baker, Prof Malcolm Gammie, Prof Dr Luis Schoueri, Dr Partho Shome, Prof Kees van Raad, Prof Jefferson VanderWolk, and Prof Richard Vann.

The overall standard of ADIT is comparable to a postgraduate qualification. ADIT is a professional qualification intended for senior level tax professionals and managers, or people working towards a senior level in international tax.


No pre-requirements to register as a student or take exams - we only require an email address so that we can keep in contact with you. Tax professionals around the world have a wide variety of backgrounds and this qualification works to ensure that there are few obstacles to improving your own, or your team's, credentials.

Flexible with work commitments and study commitments - exams are held twice each year, different exam combinations are available in both handwritten and on-screen formats, and the exams are modular so you can take the exams in any order or all at the same sitting.

Five years to graduate - your student registration expires after five years. If you find yourself beyond that time frame, with papers left to complete, you only need to re-register.

Thesis option on the subject and jurisdiction of your choice for one of two papers - should you not want to study the current jurisdictions offered, you can do a 15,000-20,000 word thesis instead of either Paper 2 or Paper 3.

Choice of study options - depending on your commitments and resources available, there are a variety of tuition choices available. In addition, you can choose a different study route or course for each paper. You are not restricted to classroom study only.

Broaden your scope

Many international tax professionals have 'learned on the job', or they are accountants or lawyers or work for the national revenue office doing international tax. This qualification truly identifies you as an international tax specialist. It will 'fill in the gaps' of your knowledge of international tax and other jurisdictions.

The exams are up to date and based on current case law. They cover the trends and what are now important areas in international tax.

Practical qualification - there is a combined focus on the academic understanding but also on the practical, 'real life' application.

A global syllabus

Uniquely cross-border in that everyone has to pass Paper 1 - Principles of International Taxation and have to demonstrate ability in two different jurisdictions or international tax subjects. And there is no requirement that the jurisdictions be where you work or live.
