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

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:

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.

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)
