Episode 17: How could your tax career benefit from the ADIT Qualification?


We’re delighted that Catriona Loughran, our Director and founder, is Jack Bonehill‘s guest on today’s edition of the Tax Professionals Podcast. Click on the link below to hear them discuss the Advanced Diploma in International Tax (ADIT).


As an ADIT graduate working in international tax, Catriona is well placed to discuss the benefits and challenges of the ADIT qualification!  To find out more, read her story here.


Talking International Tax

In this episode, Jack and Catriona talk about this prestigious tax certification, debunking any misconceptions about ADIT.  Listen as Catriona and Jack explore the ways in which it stands apart from the Chartered Tax Adviser (CTA) qualification, illustrating why ADIT is the mark of a high quality international tax professional.


During their chat, Catriona talks about the structure of the qualification.  She starts by explaining that the core module, Principles of International Taxation, is mandatory.  Jack and Catriona move on to discuss the wide range of papers available under the jurisdictional and thematic modules. This choice means that tax professionals can tailor the qualification to their own areas of interest or specialism.


Training for the ADIT Qualification

Unsurprisingly, there is a considerable commitment required for anyone planning to undertake the ADIT exams.  However, as Catriona points out, there are ADIT training providers like Extratax Training who provide structured, modular study programmes to support and encourage candidates on their ADIT journey.


In conclusion, Catriona recommends that all tax professionals consider how this international tax qualification could benefit them.

The Chartered Institute of Taxation (CIOT) brought certainty and convenience to students with their welcome decision to move all Advanced Diploma in International Taxation exams online for the June 2021 sitting.


Benefits of Online ADIT Exams

This offers you a great opportunity to sit the exams from anywhere in the world, including the comfort of your own home! This is of particular benefit to candidates who otherwise be required to spend time and money travelling to reach an examination centre.


Online exams increase the flexibility of this prestigious international tax qualification, making it even more accessible to global tax professionals.


Sitting an Online Exam with the CIOT

You will not need to select an examination centre as part of the registration process for your exam.  However, you will need to state where in the world you plan to sit the exam. This is because the exam is made available at specific times in different time zones.


You must download the Exam4 software application to sit the online exams.  Using this software, you’ll see your exam paper on one half of the screen while you type your answers on to the other half.  You do not need to remain online for the duration of the timed exam, although you will require access to an internet connection to download the exam and to submit your completed exam paper at the end.


To find out more details about the online exam rules and guidance, visit the CIOT website.

The ADIT qualification offers a fantastic return on investment. This article explains the costs of ADIT to help you decide on investing in your international tax career.


1. Mandatory Fees to Chartered Institute of Taxation

The initial cost of ADIT is registering with the CIOT as an ADIT student. This is a one-off fee of £210. Registration as an ADIT student remains valid for 5 years.

If you are already a member of the CIOT (e.g. a CTA), you may not be required to pay this fee. If this applies, you should contact the ADIT Education Team to discuss registering as an ADIT student.

There is an entry fee of £195 for each exam paper (or the extended essay option). 

Therefore, the total fees for registering as an ADIT student and sitting three ADIT papers are £795.

2. Costs for Permitted Texts

The syllabus for each ADIT module lists books which you are permitted to bring into the exam hall to use as reference materials during the examinations (known as Permitted Texts). You should include the costs of buying at least some of these Permitted Texts when evaluating the costs associated with ADIT.

It is possible to obtain free online copies of some of the materials, e.g. the UN Model Convention & Commentary, to use in your studies. However, it is not possible to bring printed versions of these materials into the exam centre, as all Permitted Texts must be bound books.

As a minimum, you should purchase the latest version of  the relevant volumes of ‘Materials on International, TP and EU Tax Law’ by Kees Van Raad. These are available to buy from the International Tax Center Leiden‘s webshop at https://webshop.itc-leiden.nl/.

The volumes and current prices for the Kees Van Raad materials are:

Volume A is essential for Principles of International Taxation and many of the optional ADIT papers, including the jurisdictional options. Volume B is essential for the Transfer Pricing module. Volumes C1 & c2 are essential for the EU Direct Taxation module.

Buying all four volumes of Materials on International, TP and EU Tax Law currently costs €190 plus postage. These materials are a good investment for any practitioner of international tax, whether or not studying for ADIT.

3. Costs of ADIT Course Providers

The most significant part of your investment in your ADIT studies is likely to be the cost of ADIT training courses. There are a variety of options on structure, delivery, pricing etc. and you’ll need to decide which options will give you the best learning experience for your investment.

The CIOT publishes a list of ADIT course providers here. You’ll have to visit their individual websites or contact them for pricing details. The CIOT recommends that you ask questions to evaluate the following factors when deciding on your ADIT course provider:

  • Style
  • Content
  • Success rates 
  • Experience and qualifications held by the tutors

You can find detailed information about the ADIT training provided by Extratax Training at ADIT Information and ADIT FAQ. We measure success not just in terms of achieving your ADIT diploma or certificate – also by how we increase your international tax skills and knowledge to help your career advancement. 


4. Benefits of ADIT 

The costs of ADIT are easier to quantify than the benefits, but we believe that investing in ADIT offers a significant return on investment. Our tutors can tell you their personal stories about their ADIT success. If you’d like to hear what senior international tax experts have to say about ADIT, visit the ADIT section of the etaxjobs website to read comments including:

“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

P.R. Bhuta & Co. Chartered Accountants | Harshal Bhuta ADIT, Partner | India

“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 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.”

Looking for more exam-standard questions as part of your preparation for the ADIT UK paper?

We’ve compiled the list below of recent past paper questions from the CTA Awareness & Advanced Technical papers which overlap with the Option 2.09 syllabus.

Our advice is to attempt these questions under exam conditions, being careful to stick to the timing of 1.8 minutes per mark. It’s tempting to read the question & then the answer, and tell yourself that ‘I would’ve got that point’! You’ll have a much better idea if this is true by writing out your answer and using the marking guides to see how you’ve performed.


Individuals, including Globally Mobile Employees

  • Deemed domicile and remittance (Q1 Taxation of Individuals – May 2019 Advanced Technical Paper)
  • Note on ‘Transactions in UK Land’ anti-avoidance (Q2 Taxation of Individuals – May 2019 Advanced Technical Paper)
  • UK employee on secondment to Germany (Q4 Human Capital Taxes – May 2019 Advanced Technical Paper)
  • Individual moving tax residence from UK to Spain (Q5 Taxation of Individuals – November 2018 Advisory Paper)
  • Note on Business Investment Relief for non-UK domiciled individual (Q6 Taxation of Individuals – November 2018 Advisory Paper)
  • Dutch company engaging a UK employee (Q1 Human Capital Taxes – November 2018 Advisory Paper)
  • Global secondments from a UK company (Q3 Human Capital Taxes – November 2018 Advisory Paper)
  • German workers coming to the UK (Q1 Human Capital Taxes – May 2018 Advisory Paper)
  • UK employee relocating to Australia (Q5 Human Capital Taxes – May 2018 Advisory Paper)
  • New Zealand resident spending time in the UK (Q1 Human Capital Taxes – May 2017 Advisory Paper)

As the CTA exams focus on specific areas of UK tax, you will find that some of the questions (e.g. Human Capital) require more in-depth knowledge than typically required for the ADIT UK option. Tackling these questions is a good way to confirm your understanding & prepare you for the challenges of the ADIT paper.


Corporation Tax & Anti-Avoidance

  • Hybrid mismatch & Controlled Foreign Companies (Q4 Taxation of Major Corporates – May 2019 Advanced Technical Paper)
  • Corporate migration (Q5 Taxation of Major Corporates – May 2019 Advanced Technical Paper)
  • Corporate residence, permanent establishment and Withholding Tax (WHT) on royalties & service fees (Q5 Taxation of Major Corporates – November 2018 Advisory Paper)
  • Transfer pricing & Diverted Profits Tax (DPT) (Q6 Taxation of Major Corporates – November 2018 Advisory Paper)
  • Scope of UK corporation tax, entity classification, Controlled Foreign Companies and international financing structures (Q4 Taxation of Major Corporates – May 2018 Advisory Paper)
  • Cross-border dividend, interest & royalty payments (Q3 Advanced Corporation Tax – November 2017 Advisory Paper)
  • Note on Diverted Profits Tax (DPT) (Q2 Advanced Corporation Tax – May 2017 Advisory Paper)
  • Acquiring a group with Controlled Foreign Companies (CFCs) (Q5 Advanced Corporation Tax – May 2017 Advisory Paper)


See the CIOT website (https://www.tax.org.uk/students-qualifications/studying/past-exam-papers) for the past papers, suggested solutions and candidate scripts. Please remember that the answers will reflect the law at the date of the exam.
