This article discusses the permitted text books for the ADIT International Tax exams.



ADIT Permitted Text

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 a Permitted Book or Permitted Text). 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.

If your exam results weren’t what you’d planned,

you might be considering an ADIT resit this summer?


We’re sharing our advice and tips for passing the ADIT exams to help you succeed!


1. Don’t be disheartened

Everyone can have a bad day!  In the exam, every second counts.  Anything that slows you down can affect your results.

It’s a good idea to think about what affected you.  Then work out what you can do about those factors, and get ready to try again.

If you weren’t familiar with the exam software, and got distracted trying to use it, then note down the things you struggled with and log in again to familiarise yourself with its features.

Perhaps you found it difficult to keep an eye on the time, and couldn’t attempt all the questions.  Or you spent too long on the lower mark questions, and had to rush through the more complex scenarios.  As part of your preparation, be sure to sit past papers in exam conditions – great time management practice.

Maybe you just had a terrible day.  If you had been ill, lost sleep, or were preoccupied with other pressures, you might not have been in the right headspace to draw on your knowledge and apply it to the questions.

Whatever the cause, if you know that you can succeed, then it is worth giving it another go!


2. Make a study plan

There are still a few months before the June exams.  If you plan to enter again, which you need to do by March 31st, then this is exactly the time to make plans.

You might have already read our helpful guide for getting ‘Ready, Steady, Go’ to study again, published on the CIOT website?  If not, you can access it here.  It is full of practical advice and tips for getting into good study habits as you prepare for your next exam.


3. Find resources to support your study

You probably invested considerable time and effort in preparing for the exam, and are finding it hard to get motivated again.  Why not look for different resources to support your study?  You could find new and interesting ways to test the application of your knowledge.

You can access ADIT past papers on the CIOT website here.  There are discussion groups on social media, such as the ADIT Professional Group on LinkedIn, where you will find others in your peer group who are tackling the same issues and sharing their learning.

At Extratax Training, we publish a weekly ADITextra blog.  This summarises what’s been taught and discussed in our live online classes.  You’ll find updates from our sessions on Principles of International Tax (Module 1); UK Paper (Module 2.09); US Paper (Module 2.10); and the Transfer Pricing Paper (3.03). You can also subscribe to our YouTube channel to watch parts of our classes covering key topics.

This is a great way to benchmark your own learning and check you’re progressing.  Follow us on Twitter @TrainExtratax and LinkedIn @Extratax Training to keep up to date with our blogs and advice.

4. Go for it

Commit to a regular study schedule and don’t get distracted.

Get used to typing as you think, rather than writing on paper.

Practice, practice, practice your exam technique by attempting past questions in exam conditions – timed, and with only permitted texts.

Spend time familiarising yourself with the Exam4 software (we’ll soon be posting advice from our past students on using Exam4, so keep an eye out for that!).

Most importantly, remember to take regular breaks from studying.  Step away from the books to go for a walk, catch up with a friend, even just to have a drink of water, and come back refreshed and ready to get to grips with the material again!

Good luck with your ADIT exam!

Why does student feedback matter?

We’re committed to supporting every one of our ADIT candidates on their professional journey.
We believe the best way to do this is to find out what you need to succeed, and to provide it!


See what our students had to say on:


Choosing an ADIT study provider

I wanted someone to guide me as I had no clue about international tax or the ADIT Program.  Catriona’s openness, willingness to listen and give advice to a complete stranger, whilst not marketing her firm, convinced me to train with Extratax. It ended up being one of my best decisions in 2020.

Everyone is unique.  At Extratax Training we appreciate that the process of learning is different for each individual.  We are very open about the style of tuition and study support that we provide, so that prospective students understand the commitment involved before they book their place.


Course logistics

Start the course earlier as the time is too short to exams, especially to allow students without practical background time to catch up.

In response to this feedback, we extended the length of some of our live online classes this year, and included a mid-semester break, as well as the revision weeks we already include at the end of each course.

Most of our students are juggling a career alongside their family commitments.  We want to ensure the Extratax Training programme helps you to enhance your professional development in the most manageable and enjoyable (!) way possible.


The structure of the course was extremely beneficial for myself. It helped me to keep on with studies during extremely busy time at work

We spread the live online tuition across a 10 week timetable, and make the slides and recordings of these sessions available for students until the end of the semester.  This aids revision and allows everyone to catch up, or consolidate learning, at your own pace.


Tuition & exam practice

Participation from the rest of the students is really helpful because they sometimes bring a different perspective.

Our tutors set assignments and mock exam questions throughout the semester, which are marked and returned.  Everyone is encouraged to ask questions in the live classes, to share experiences and knowledge with their fellow tax students, and seek one to one support from their tutor when they need it.

I liked the ability to ask questions right on spot during classes…


Our expertise

The faculty is a big strength in Extratax – very knowledgeable not only on tax but knowing the ADIT program inside out. The advice shared by the Director, who herself is ADIT qualified, was invaluable to me as someone without previous understanding of the programme or the content.

Catriona Loughran and James Ryan lead and teach our ADIT exam study programmes.  Both are experienced international tax professionals, with outstanding practical knowledge in their field.  You can find out more about them on our website.

You’ve heard enough from us!
We’ll give our students the final say…


“I am a 20 years Professor of International Tax Law in Mexico. Finding Extratax Training to prepare me for the ADIT exams was a blessing! They give great personalized teaching, with in-depth information, well organized and up to date.”

“Well structured course with plenty of useful practical tips.”

“I love how, as someone with no previous UK Tax experience or knowledge, the course made it possible for me to actually really understand and grasp the concepts.”

“After the course, I am not only feeling that I am ready for the exam but also see extreme improvements in my technical expertise that I can apply right on spot at my job.”

“The ADIT tutors are very knowledgeable and present the materials and theoretical concepts in a way to facilitate understanding much more easily than just reading them.”

“The classes and e-book are all you need to excel in your exam.
Thanks Catriona & team!!!”

Visit our ADITextra blog to find out what our ADIT students have been studying this semester.

Welcome to ADITextra – the new blog for ADIT students from Extratax Training. Here you’ll find out what’s been happening in our online ADIT courses each week.


You’ll learn more about our study programmes and how we support your ADIT journey. And if you’ve chosen the self-study option for your international tax exams, you can follow our training schedules as a guide to keep you on target.


Each week, we’ll select a key topic from one of the classes for the Spotlight section. We’re starting with Fundamental Sources, Part I of the Transfer Pricing syllabus. Find more information and watch part of the lecture in Section 5 below.


The live tuition classes for the June 2021 exam session started this week. The exams are four months away – it might seem like a long time, but the weeks will soon pass and it’s important for you to get started as soon as you can.


If you’ve registered as a candidate for the Advanced Diploma in International Tax, but are not sure where to start, check out our blog on your first steps.

1. Transfer Pricing

We kicked off the semester on Tuesday with the ADIT Transfer Pricing module, taught by James (Jimmy) Ryan. Jimmy has a wealth of knowledge about transfer pricing. In addition, he’s highly engaging and invests in his own continuous learning to share the latest information with his students. Firstly, he gave a warm welcome to his new ADIT students.


After setting the scene, Jimmy dived into the ADIT syllabus, covering fundamental sources. Then he moved on to introduce the core transfer pricing principles of ‘associated enterprises’, the ‘arm’s length principle’ and comparability. This week, the spotlight is on fundamental source for transfer pricing. Check out Section 5 below to learn more and watch part of the class.


It wasn’t long until we received our first piece of feedback. During the class break, one of the students emailed to say “Jimmy is great!” That’s what we love to hear, as it’s all about delivering a valuable training experience to ADIT candidates.


Recording of Live Classes

Once the live class ends, it is Holly’s time to shine. Holly is the course co-ordinator and uses her video editing skills to turn the two-hour live class into four bitesize videos. Our students can watch the videos any time, and as often as they like, to improve their understanding or revisit a key topic.


There’s still time for you to join the Transfer Pricing course – we’re accepting bookings until 8 March. You can catch up on the classes by watching the recordings and you’ll have one-to-one access to Jimmy and the team to get you fully up to speed.



2. Principles of International Tax

Jimmy was back on Wednesday to begin this semester’s Principles of International Tax course. Straightaway, he greeted the brand new students to Extratax Training and welcomed back some familiar faces from the 2020 Transfer Pricing class.


After an introduction to the course, Jimmy explained the legal concepts around jurisdiction to tax – i.e. how do you assess a state’s jurisdiction to tax an individual or entity? Of course, he quickly referred to the OECD’s Model Tax Convention. Obviously, understanding the Model Tax Convention and its impact on international tax is fundamental to the course.


One of Jimmy’s key skills is explaining international tax case law, summarising the facts and highlighting the importance of the decision. As the class progressed, he discussed significant cases in this area, including the UK Court of Appeal’s decision in Jimenez -v- HMRC.


Then Jimmy shared an overview of the topics to be covered in more detail in later sessions. These are the foundations for understanding and applying international tax law – source taxation, personal residence, domicile, corporate residence and treaty tie-breakers on residence.


After the Online Class

At Extratax Training, we focus on bringing tax professionals from around the world together into a global community. So it was fantastic to see the Principles of International Tax participants immediately starting to use our learning portal to ask the tutors questions and support each other through their ADIT studies.


Naturally, the learning doesn’t stop when the class ends. In order to succeed, the participants have to spend time on recommended reading for this week’s topics and prepare their first weekly assignment. It’s important to balance reading the permitted texts, and other materials, with practicing questions. Above all, we help you focus on the fundamental areas to study and improve your exam technique.


It’s not too late for you to join the Principles of International Tax course – you can book online until 8 March. And don’t worry, you can catch up on the classes by watching the recordings. Plus you’ll have one-to-one access to Jimmy and the team to get you fully up to speed.



3. UK Tax

Next, it was time for the UK Tax class on Thursday. Our founder, Catriona Loughran, is the lead tutor for this course. She’s an experienced UK & international tax specialist, with over 20 years’ experience spanning professional practice, HM Revenue & Customs and in-house tax for multinationals.


Our UK Tax course is designed to be suitable for tax professionals with little or no UK tax experience. We love bringing together candidates from across the globe to study the UK module. Therefore, it was fantastic to welcome ADIT students from the United States, Netherlands and Zambia, along with their UK counterparts.


The United Kingdom 

So, where do you start with the ADIT UK module when the syllabus is so broad? Well, Catriona started by looking at the United Kingdom itself. If you’re from the UK, you probably assume that everyone knows which territories form part of the UK, but do they? England, Wales, Scotland and Northern Ireland are the easy ones, but what about, say, the Isle of Man? It could well feature in an ADIT exam question. So, it’s important to know that, while it is deemed to be part of the UK for VAT purposes, it’s otherwise a separate state. It has its own tax laws and double taxation agreements with the UK.


Because this was an introductory session, the focus was on giving an overview of key topics to be covered in future weeks. As you might expect, there was a high degree of overlap with Jimmy’s Principles of International Tax topics – double taxation, source taxation, personal residence, domicile, corporate residence and treaty tie-breakers on residence – but considered from a UK perspective.


The ADIT UK Tax syllabus states that candidates are expected to have some understanding of the major UK treaties, with the US, Netherlands, France and Germany mentioned in particular. Therefore, Catriona makes sure that she references the terms of these treaties when discussing subjects such as the implementation of the Multilateral Instrument in the UK.


Interactive Learning

Thursday’s class was an engaging and interactive session. The participants benefitted from being part of a small learning group, asking questions when they wanted Catriona to clarify a point or give an example to illustrate a concept.


Extratax Training has produced its own set of e-learning materials, written specifically for UK Module 2.09 by leading international tax experts. After the class, Catriona set the chapters to be completed this week, along with the first weekly assignment. There’s a Brexit theme this time, as the students have to advise a UK plc on repatriating funds from its German subsidiary pre- and post-31 December 2020.


You can still choose to join the UK class – the deadline to book is 8 March. You can catch up on the classes by watching the recordings. Plus you’ll have one-to-one access to Catriona and the team to get you fully up to speed.



4. US Tax

Although there were no classes on Friday, it was a great day for ADIT education! Catriona engaged an excellent US & international tax practitioner to lecture the ADIT US Tax module. We’re excited to be able to welcome ADIT students studying US Tax for the first time.


Live online classes are starting on Thursday 11 March. Follow us on LinkedIn, as we’ll reveal more in the coming weeks.


As the US Module 2.10 is new to our portfolio, we’re offering you the opportunity to book for June 2021 at a special introductory rate.



5. Spotlight on Transfer Pricing – Fundamental Sources

Each week, we’ll put the spotlight on a topic covered in one of our classes. Firstly, let’s look at Fundamental Sources from the Transfer Pricing course.


There are six fundamental sources listed in the ADIT Transfer Pricing syllabus:


In addition, don’t forget about the new Chapter X of the Transfer Pricing Guidelines – Transfer Pricing Guidance on Financial Transactions. The OECD released this report in February 2020. As new guidance, it is highly examinable. You should make sure that you understand the guidance and its application.


The syllabus lists the report as a Permitted Text for the Transfer Pricing exam, so you can bring an authorised copy into your exam room and refer to it in your answers. However, you won’t gain any marks by copying from the text. To pass, you’ll need to be able to discuss it and apply it to a scenario.


Article 9 – Associated Enterprises

Watch this excerpt from this week’s Transfer Pricing class to learn about Article 9 of the OECD Model Tax Convention. Also, you’ll hear Jimmy give a succinct definition of transfer pricing. Learning to explain complex topics in a concise manner is a key skill to master for the ADIT exams.



There’s still time to join our Transfer Pricing course – book today and let us guide you to ADIT success.

Well done, you took the plunge and registered as an ADIT student for 2021!

There’s a few weeks left before the June 2021 exam entry deadline on 31st March*, so this is the time to get yourself organised for sitting an exam this term.

1. Structuring your exam plan

It’s tempting to go all out and enter for three exams at the outset.  While this may be achievable, you’ll need a great deal of time to commit to studying in order to be successful in all three papers in one sitting.

We recommend taking a maximum of two exams first time round.  You have 5 years initially to complete the qualification, and it’s well worth spreading the workload so that you don’t take on too much at the outset.

Getting to grips with one ADIT module syllabus at a time means you have the space to really apply your learning to your work, as well as keeping that all-important balance between your professional and personal life!

2. Choose your module(s)

As you know, the Principles of International Tax module is compulsory, and you must also sit one jurisdictional paper and one thematic paper to complete the ADIT requirements.  You may write an extended essay in place of one of these modules, which is a great option if you have a particular niche interest or specialism.

It is good to be aware that in June each year there are exam sittings for every paper offered, whereas only a specific set of papers are examined in the December sitting.  Click here and take a look at the ADIT exam information for more details.

With all this in mind, you might want to consider which papers you sit in which season.  There’s a view that Principles of International Tax is a good paper to do first, because it offers a general framework for the exams.  However, if you plan to take a paper in an area in which you already specialise, then you might prefer to take that first as it is likely to give you a strong start on your ADIT journey.

When you’ve decided which module(s) to take, you can enter online here.

*Don’t forget the deadline for entering June 2021 exams is 31st March 2021.*

3. Work out a study schedule

It’s never too early to do this!  If you start now, you will be able to work your way through the module syllabus over the next three months, still leaving yourself time for revision and exam practice before the real thing.

The crucial thing about a study plan is sticking to it.  If it starts to slip, make a real effort to put in the extra time to catch up straight away.  Falling behind on your schedule can make the amount of work required appear more daunting than it needs to be.

If you are one of the many people who find it helpful to learn in a group, or with structured tuition, then choose a registered course provider to help you prepare.

Extratax Training are a registered ADIT course provider.  You can check out our ADIT study programmes here.  All our tuition takes place in live, online classes where we encourage everyone to participate and learn together.  The courses run over a 10 week period, and tutors host intensive revision sessions to consolidate your learning before the exams.

4. Purchase set texts

Now you’re a registered ADIT student, you should buy Professor Kees Van Raad’s Materials on International, TP and EU Tax Law Volume A.  This will be an essential resource all the way through your qualification, so it is money well spent!

Candidates who join one of our Extratax Training study programmes will be provided with a set text to support learning for the module in question.  This is included in the course fee.

*Be absolutely certain you have read and understood the guidelines about marking permitted texts before you write on any of them.*

5. Start learning!

Knowing where to start can be tricky.  Extratax Training take the worry out of this by working through the syllabus logically, and providing a forum for discussion of topical and practical issues.  Our online sessions are a great opportunity for all students to ask questions and to learn from the experience of their international tax colleagues in the seminar.

* The June 2021 ADIT exam entry deadline has been extended from 16th March 2021 to 31st March 2021. If you’re not already a registered ADIT student but want to sit an exam in June 2021, contact the CIOT at to enquire about late registration.

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.

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

What is ADIT?

You’re progressing in your international tax career, and you keep hearing about the ADIT qualification.  Do you know what it is and why it’s so talked about?

ADIT is the Advanced Diploma in International Taxation.  Attaining this qualification is a great way to enhance your standing as an international tax expert.

How do I get started?

Register with CIOT as a student

The first step is to register online with the Chartered Institute of Taxation (CIOT) as an ADIT student. All you need is an email address!  It costs £215 and your registration lasts for 5 years.

Students must be registered by a certain date before each exam sitting.  For example, if you want to sit your first ADIT paper in June 2021, you must have completed your student registration by 31 January 2021.  You’ll find more details on the CIOT website here.

Choose your path to qualification

You must select which modules to sit!

ADIT students must pass the compulsory Paper 1 (Principles of International Taxation), along with EITHER two optional modules OR one optional module and an extended essay.

Exams take place in June and December of each year, and you can sit up to three papers at one time.  However, that would be an enormous commitment in terms of preparation, and most people choose to sit one paper per session.

You can find information about each paper in the ADIT Prospectus & Syllabus. For a summary of the options, check out my blog post on what ADIT offers you.

Register for your exam(s)

Providing you are already registered as a student, you can register to sit an exam.  This costs £195 per paper, and it is important to register before the deadline for each sitting as there is a penalty for late entries.  There is more information here.

Get started!

When you register for the exam, it is months away…but that time flies!  It’s a good idea to get your study underway at least 3 months prior to the exam sitting.  This gives you time to work through the topics, consolidate your knowledge, and still have time to practice, practice, practice with those past papers.

Get to grips with the materials

The ADIT syllabus for your chosen module lists the ‘permitted texts’ which are the books you may use during the exam.  These are essential purchases – you need to get familiar with them!

Each syllabus also contains a list of recommended texts. If you intend to undertake self-study, do some research on each of the books listed to decide which ones will be the best use of your time and money.

Get support

To maximise your chance of ADIT success, you may decide to join an ADIT training programme.  It is helpful to learn alongside your peers, so that you can discuss topics and share understanding and techniques.

Extratax Training is one of the recognised ADIT course providers. We offer comprehensive online study packages for:

  • Principles of International Taxation
  • UK Tax (Module 2.09)
  • Transfer Pricing (Module 3.03)

When you choose Extratax Training as your ADIT study partner, you’ll:

~ Join like-minded tax professionals in a virtual classroom for weekly tuition sessions delivered by international tax experts

~ Receive study materials designed to support your learning needs

~ Become part of the Extratax Training community to share your experience and grow your network

Do you want to improve your international tax expertise and gain a globally recognised international tax qualification? Read on to find out about the benefits of the ADIT qualification.

ADIT offers you the opportunity to go beyond your own country’s tax system and learn about how tax systems interact. In an increasingly global world, where even the smallest businesses can use technology to expand overseas, ADIT gives you a robust foundation in international tax to make you stand out from the crowd. There has never been a more exciting time to be an international tax specialist!

ADIT is a practical qualification – combining academic understanding with real life application. ADIT is an advanced level designation in cross-border tax designed by a board of world-leading experts. You may already be working in international tax, having learned ‘on the job’ – the ADIT qualification fills the gaps in your knowledge and identifies you as a true international tax specialist.


One of the benefits of ADIT is that it offers a high degree of flexibility, allowing you to balance work & study commitments. The exams are modular, so you can take them in any order or all at the same sitting. You have plenty of time to complete the qualification, with at least 5 years to graduate. To graduate, you must pass the compulsory Principles of International Taxation paper plus two optional modules, or one optional module and an extended essay on the subject & jurisdiction of your choice. The only prerequisite to register as a student & take the exams is an email address!

If your home jurisdiction doesn’t offer a tax qualification on a par with the Chartered Tax Adviser qualification, studying for ADIT and becoming an International Tax Affiliate of the UK Chartered Institute of Taxation is your chance to gain a globally recognised tax qualification. When you become an International Tax Affiliate, you demonstrate your commitment to upholding the highest professional standards, and highlight your technical expertise and dedication to your career.

The core module – Principles of International Taxation – gives you a solid foundation in international tax without focusing on any one jurisdiction. Its syllabus covers key issues such as principles of international tax law, residence, double taxation conventions and treaty interpretation, transfer pricing, the work of the OECD and international tax avoidance.

You have free choice over your selections for the other two modules. You may choose to focus on the thematic papers to further develop your understanding of international tax in specific areas. Or you may choose to learn more about international tax rules in a neighbouring jurisdiction and a common headquarters jurisdiction, like Singapore or the UK. Or you can choose to mix a thematic & a jurisdiction option.

ADIT gives you the flexibility to design an international tax qualification that meets your needs.

The thematic options are:

  • EU Direct Tax – examines the impact of European Union Law on all aspects of direct taxation for all Member States, including the background to EU Law in the Treaties, and the role of the various EU institutions.
  • EU VAT – examines the European Union Law on Value Added Tax (VAT) which governs the VAT system in all Member States, including the fundamental concepts of EU Law, the provisions of the VAT Directive & other EU VAT legislation, and the application of EU Law by the Court of Justice in decided cases
  • Banking – covers international taxation of the banking industry, including investment banking, capital markets, global markets, asset financing, asset management, private banking and wealth management.
  • Upstream Oil & Gas – examines the taxation of upstream oil and gas operations in an international context, addressing fundamental tax issues within the oil and gas sector, including a number of country examples, permanent establishments and transfer pricing methods, the taxation of intellectual property, mergers and acquisitions, financing and trading activities within the sector.
  • Transfer Pricing – covers the fundamentals of transfer pricing based on the OECD model, focusing on transfer pricing methods, the arm’s length principle, comparability, compliance issues and avoiding double taxation and dispute resolution.

The jurisdiction options are:

  • Australia – covers the structure of the Australian tax system with particular emphasis on Income Tax, Fringe Benefits Tax and Goods and Services Tax.
  • Brazil – covers the structure of the Brazilian tax system with particular emphasis on the principle of territoriality, taxation of individuals, companies and non-residents, and Brazil’s international tax treaty network.
  • China – covers the structure of the Chinese tax system with particular emphasis on Individual Income Tax, Enterprise Income Tax, and inbound and outbound investment taxes.
  • Cyprus – covers the structure of the Cypriot tax system, with particular emphasis on Income Tax, Capital Gains Tax and Value added Tax, and topics such as the Cyprus Double Taxation Treaty Network, reorganisations and BEPS.
  • Hong Kong – covers the Hong Kong income tax system as it affects individuals and corporate businesses, with particular emphasis on international trading, and includes various special categories of taxpayer, tax administration, double tax relief and tax planning.
  • India – covers the structure of the Indian taxation system with particular emphasis on income tax (including income tax on capital gains) and wealth tax, and addresses tax jurisdiction (including territoriality), taxation of individuals, taxation of companies, tax planning, use of tax treaties, tax procedures, withholding taxes, and tax administration.
  • Ireland – covers Irish personal, corporate and indirect taxes in an international context, along with double tax relief, reorganisations, transfer pricing, cross border issues and anti-avoidance.
  • Malta – covers the structure of the Maltese tax system with particular emphasis on Income Tax, Income Tax from Capital Gains, Property Transfer Tax, Duty on Documents and Transfers and VAT.
  • Singapore – covers the main income taxation issues typically encountered by global businesses operating in a territorial-based taxation economy that is highly dependent on international trade.
  • United Kingdom – covers areas such as UK CFC legislation, double tax relief, thin capitalisation, reorganisations, transfer pricing, application of corporation tax to cross-border situations and anti-avoidance provisions.
  • United States – covers federal income tax in detail (with particular emphasis on inbound and outbound cross-border situations, US tax treaties, transfer pricing and cross-border mergers and acquisitions), along with the basic rules of, and cross-border issues in, the federal estate tax, the federal gift tax, and state and local taxes.

As an alternative to one jurisdiction or thematic exam module, you have the option of writing a 15,000-20,000 word extended essay. This is a great option if your chosen area of international tax is not covered by an available ADIT module options or if you are completing a dissertation or thesis as part of an LLM or masters degree in international tax – a version of your dissertation or thesis may be submitted in fulfilment of the ADIT extended essay option (provided it meets the ADIT extended essay requirements.) Or perhaps you simply wish to gain the experience of researching and writing an advanced level extended essay that contributes to the academic discourse in a specialist area of international tax?

Did you know that you can also obtain modular and standalone certificates from the CIOT?

ADIT students who successfully complete Principles of International Taxation and one optional module may apply for a modular certificate recognising their partial ADIT achievement. Students who pass either Principles of International Taxation or a thematic module can alternatively apply for standalone certification. The modular certificate is a great option to demonstrate your growing expertise as you work towards becoming an ADIT graduate.

The standalone certificates are ideal if you are interested in gaining a qualification in one specialist area of the ADIT syllabus, for instance, transfer pricing. Or maybe you are already an ADIT graduate but wish to continue to expand your international tax knowledge by studying a further thematic module!
