What ADIT people say

Since the first ADIT exams took place in 2004, the number of international tax professionals pursuing ADIT has continued to grow.

Today, the ADIT network includes students, graduates and International Tax Affiliates from more than 1,400 employers in over 110 different countries and territories around the world. You can find a selection of their comments about ADIT below.


"I have found the ADIT to be an invaluable asset in my international tax career. The pursuit of the qualification has, to date, provided me with both the theoretical understanding of many of the issues faced on a day to day basis as well as helping me to apply that theory to practical scenarios. In a competitive industry I have found the pursuit of the qualification to be acknowledged by both my peers and by employers as a unique selling point on my CV.”

Creaseys | Carron McKinney ADIT, VAT Director | UK


“ADIT provides in-depth knowledge of cross-border tax, invaluable to a global company like Michelin. It enhances the value that I am able to add to the business and provides opportunities to extend my horizons beyond the UK.”
Michelin | Robert Johnstone ADIT, Director of International Taxation | Singapore


“It can be quite difficult for international tax specialists to acquire a deep and broad technical knowledge base on which to build their practical experience. The ADIT is a unique qualification which perfectly meets this need and was designed with this in mind. I would regard the ADIT as a huge advantage when recruiting for international tax specialist roles.”
HM Treasury | Paul Morton, Office of Tax Simplification | UK


“In recommending an international tax qualification for our staff to pursue, we reviewed what was available in the global marketplace and concluded that ADIT, with its modular structure that combines international tax skills with experience in one of a number of major domestic tax systems, was a very good fit for our competency development requirements.”
Shell | Jim Robertson, VP Tax | USA


“Studying ADIT and gaining the qualification proves to your employer that you are serious about international tax and about pursuing an international career. Studying for ADIT has allowed me to build up broader knowledge in international tax than I would get by just gaining experience on the job.”
Proctor & Gamble | Doris Gonzalez-Hurtado ADIT, Associate Director, Taxes CEEMEA | France


“ADIT is a qualification which will help you gain an in-depth understanding of international taxation and of a home country and a second country’s taxation system. While you prepare for the ADIT Papers, you continue to build a better understanding of international tax. I passed the Hong Kong and China Option Papers and use this expertise to benefit my clients and employer.”
HLB Hodgson Impey Cheng | Grace Xia ADIT, Senior Tax Consultant | Hong Kong


“Not only does ADIT provide a USP for your CV, but there is also a compelling business case to have a tax professional in-house who understands the concepts, and the hard cash reality that it saves advisor fees in dealing with the areas most would instantly outsource. Being a modular qualification, ADIT also helps me better manage my study and manage the demands of my work and home life. For any tax professional, keeping abreast of tax developments is a precondition to doing the right thing both professionally and for the business. With the tax agenda firmly being on improving the effectiveness and collaboration of jurisdictional tax systems, studying for the ADIT qualification puts you at the cutting edge of that.”
Drax Group | Martin Harris, Head of Tax | UK


"In the aim of finding a qualification to broaden my career prospects I got to know the CIOT, and then ADIT, and registered as a student. As I continue to build my experience and expertise in international taxation, I am convinced that having this qualification will contribute to improving both my knowledge and career prospects."
Philip Morris | Florencia Ali, Latin America Services | Argentina


"The addition of the ADIT qualification was a clear choice to enhance our offering as an independent consultancy. It strengthens our own brand, and offers our clients the security that the advice they receive is of an assured, global standard. We have not looked back."
Priority Tax Consulting | James Ryan ADIT, Principal | Ireland


"In pursuing ADIT, I have been able to acquire an understanding of the structure of treaties which enhances my professional expertise; my ADIT studies have also served to refresh my knowledge of legislation, whilst remaining up-to-date with new developments within a fast-changing international tax environment. The syllabus includes a strong corporate focus, and has proved highly relevant to my day-to-day work at EDF, whilst the freedom to select a second jurisdiction paper enables me to develop my expertise across multiple tax systems."
EDF | Karen Fisher ADIT, Senior Tax Manager | UK


"In pursuing the ADIT exams, I developed a strong technical understanding of international tax issues, and by successfully completing ADIT I was able to gain the confidence to apply this technical knowledge of important topics affecting my clients, such as transfer pricing and permanent establishments. My success, first as an ADIT student and now as an International Tax Affiliate of the CIOT, has not only assisted my self-development, but has helped me to gain significant recognition as an international tax practitioner."
Grant Thornton | Quang Tran-Trung Phan ADIT, Tax Manager | Malaysia


“Coming from an accountancy background, I found that, in pursuing ADIT alongside an LL.M. at Leiden, I was able to benefit from a syllabus that enabled me to study for both qualifications simultaneously, and obtain both academic and professional certification within my chosen international tax subjects. Selecting the Transfer Pricing paper challenged me to develop a detailed understanding of a complex subject that has become very pertinent within the current international tax environment.”
Amicorp | Cora Cheung ADIT, Senior Relationship Manager, Product and Restructuring | Singapore


“One of the benefits of ADIT is that it gets you to understand the why behind the rules. Understanding the principles really helps when approaching international tax issues in practice. My international tax Masters was a useful preparation, but the Diploma is significantly more demanding. Nevertheless the syllabus, including the ADIT extended essay option, enabled me to use my academic experience as a foundation for successfully achieving the Diploma.”
Chantrey Vellacott | Jeremy Norman ADIT, Tax Consultant | UK


“ADIT is an essential qualification for international tax practitioners.”
Telles de Abreu Advogados | Joao Araujo ADIT, Lawyer | Portugal


"As an international company in 45 countries it is important that they have staff who have proved their knowledge and level of skills. It helps in risk management because you know people have skills because they have proved it by successfully completing the ADIT qualification." (International insurance)


"Very important in a group of companies that there be people who specialise in and focus on international taxation. It is also a competitive advantage for a company. Other companies have accountants doing tax but not someone who specialised in tax." (Pharmaceuticals)


"Added level of confidence especially when dealing with high level lawyers in other countries. It is that added confidence that the ADIT brand brings." (Tax advisory)


"I had never stood back and looked at the overall tax structure as when you learn by going along and pulling on levers without understanding the engine. The ADIT course is fantastically good at helping you understand the engine. With associated companies in other countries it was very helpful to study another jurisdiction. It helps me progress within my organisation because I can apply ADIT in my day job." (International consumer goods)


"I'm getting the theory because in my day-to-day job I'm doing it but didn't have the 'why' I'm doing it. The course is very up to date and it's always based on current case law and covers the trends and what important areas are now. It provides a better foundation and the basics of international tax."
