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.

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
