A guide to success in the ADIT Transfer Pricing exam

Jun 3 / Catriona Loughran





Sitting the ADIT Transfer Pricing exam can seem daunting, but with the right approach, you can tackle it confidently.

In this blog post, Catriona Loughran, who has been tutoring the TP paper for four years with a high success rate, shares her expertise to help you succeed in this challenging but rewarding exam.


1. Understand the Module 3.03 Exam Format

Managing your time effectively in the ADIT Transfer Pricing exam is crucial, making every minute count.

Let's start with the exam format. Like other optional ADIT modules, the TP paper is divided into three parts:

• Part A: Two mandatory questions worth 25 marks each. These are typically case studies testing the fundamentals of TP, such as comparability analysis, choice of TP methods and identifying TP risks.

• Part B: Two questions worth 20 marks each – choose only one. These questions may focus on more specialist areas of transfer pricing, for example, business restructuring or permanent establishments.

• Part C: Three questions worth 15 marks each - answer two. This is a key change for the June 2026 exam onwards. Part C used to be a choice of two out of five questions - now, it is two out of three. This significantly reduces your choice and means you need to ensure you're comfortable with a broad range of topics across the syllabus.

Part C questions are often split into multiple components, covering various topics such as transfer pricing of specific transactions (like services or intangibles), dispute resolution and case law. Choose your Part C questions wisely and leave yourself enough time to answer them thoroughly.

Remember that you must only answer five questions – both Part A questions, one of the Part B questions and two from the choice of three Part C questions. Additional answers won't earn you any marks and will waste valuable time.

2. Manage your Time Effectively

Time management is crucial - make every minute count! You have 3 hours and 15 minutes. While the first 15 minutes is no longer mandatory reading time, I recommend using it to read the paper, select your questions, and plan your approach.

The remaining three hours give you 1.8 minutes per mark - stick to this timing:

• 25-mark questions (Part A): 45 minutes each
• 20-mark questions (Part B): 36 minutes
• 15-mark questions (Part C): 27 minutes each

For questions with multiple parts, divide your time based on the marks allocated to each component. When your time is up, move on - you can always come back later if you have time.

Sitting at least one mock paper under exam conditions is the best preparation for managing your time in the exam. You may not get it right initially, but you'll learn from your mistakes. Success comes from attempting all five questions well - completing only four makes passing much harder. As with most things, practice makes perfect!


3. Be Strategic in your ADIT TP Exam

Use the first 15 minutes to choose your questions and decide on the order that you’re going to answer them in. The best way to figure out what works best for you is to sit two or three mock papers under exam conditions.

Here are my tips:

• Start with a Part C question. These theoretical questions can build confidence. Questions with smaller components (like 5+5+5 marks) often yield marks more efficiently. Starting with a familiar Part C topic might save you time for Part A.

• Tackle Part A next. These questions are worth 50% of the marks and require you to apply your TP knowledge to the scenarios. While it's tempting to spend more than 45 minutes on each, remember the rule of diminishing returns - the final 30-40% of marks are hardest to achieve and rarely justify extra time. I've shared my advice on the best way to approach these questions below.

• After 1.5 hours on Part A, move to your Part B question. These often involve complex concepts, so choose the question you're most comfortable with and focus on familiar aspects. Remember: you only need 50% to pass - don't fixate on difficult sections when you can demonstrate expertise elsewhere.

• End with your second Part C question. Ideally you will have 25 minutes left to answer it. If time management hasn't gone to plan and you're down to 10–15 minutes, don't panic. Use bullet points and note key points. Scoring 2+2+2 on a three-part question gives you 40% - which can balance out with a stronger performance in another question.

4. Scoring Well in Part A Case Studies

Part A of the Module 3.03 exam may appear as one large case study covering questions 1 and 2, or as two separate cases. You are usually asked to work through a transfer pricing analysis. It is critical to apply your TP knowledge to the facts given – while you can reference the OECD Transfer Pricing Guidelines, direct quotes won't earn marks.

Here are my key tips for doing well in Part A questions.

Accurately delineate the transactions

Read the facts in the question carefully to work out what intra-group transactions are taking place. You can take blank paper and pens into the exam – use them here to draw a group structure and the transections taking place between each of the companies. Consider both sides of each transaction – i.e. when Company A sells to Company B, Company B is buying from Company A.

You will have to deal with uncertainty in the questions. The facts presented will not give you the full picture and may contain conflicting information. Don't let this panic you, it's all part of the examination process. Practising the case study questions from past papers will help you learn to accurately delineate the transactions and perform a function analysis despite these challenges.

Conduct a functional analysis

When asked to undertake a functional analysis, look at the functions performed, assets used, and risks assumed by each of the parties to each of the transactions. Some of the FAR analysis can be taken directly from the facts in the question (e.g. a manufacturer will have a factory). Other aspects of the FAR analysis require you to consider the value chain - i.e. what does this group do and how does it impact on its business - and work out what that means for each entity's functions, assets and risks. For example, a pet food manufacturer will have different risks from a video games developer. The examiner is looking for you to apply your TP knowledge to the specific business discussed in the question.

Know before you go into the exam how you plan to set out your functional analysis. A table format works well for presenting your functional analysis, but make sure that you have practiced using them in Exam4 beforehand.

Identify and explain appropriate transfer pricing methodologies

  • Start with the CUP method - the facts may suggest the presence of an internal CUP, which you should evaluate.
  • Show how your chosen transfer pricing method links to your functional analysis.
  • Remember to identify the tested party for a one-sided method.
  • When recommending TNMM, suggest an appropriate profit level indicator.
  • Talk about why a method may not suitable, as well as why your selected method is appropriate.


When you are practising past paper questions, you might find that your proposed method for a transaction doesn't match the suggested solution. This is often fine, as there can be different interpretations made and conclusions reached on the same facts.

Your recommended method should be appropriate based on your analysis of the facts. For instance, if you have determined that one party to the transaction is complex while the other is routine, it would then be incorrect to suggest using the Profit Split Method for the transaction.

Highlight potential issues, risks and concerns

This is an important aspect of the whole ADIT TP paper, not just Part A. Don't assume that the facts presented in the question represent an appropriate application of the arm's length principle.

You may be asked to put yourself in the role of tax auditor. Think about what might concern the tax authorities in that jurisdiction. Watch out for entities in high-tax territories with high functionality but low profit margins, and conversely, entities in low-tax jurisdictions with limited functionality but high profits!

5. Final Tips for Maximising your Marks

Helpful tips for ADIT exam day:
  • Keep answers straightforward. Examiners want clear, structured responses showing understanding, not revolutionary theories.
  • If you get stuck, summarise key points and move on. It's better to attempt all questions than perfect just one.
  • Use plenty of bullet points - examiners appreciate them!

Best of luck with your exam. Whatever happens on the day, studying for this paper builds your transfer pricing knowledge, benefitting your career.
