LAWS6128: Comparative International Taxation

Intensive August - September, 2026 [Block mode] - Camperdown/Darlington, Sydney

Comparative International Taxation is a detailed study of the basic principles of international taxation (residence, source, relief from international double taxation, anti-deferral rules, withholding tax, transfer pricing, thin capitalisation, and tax treaties). The unit is taught from a global perspective with the emphasis being on comparative analysis (focusing particularly on Anglo, US and continental European approaches, and also developed and developing country approaches). The unit examines the core issues in developing international tax rules and identifies different approaches countries have taken in dealing with these issues. As part of this study, recent trends in international tax rule development will be identified (particularly in the context of globalisation) and critiqued. Students should gain an understanding of the different approaches that countries have taken in the development of their international tax rules.

Assessment summary

Early Feedback Task (0%): This unit includes an Early Feedback Task that is designed to provide students with timely insights into their understanding and engagement with the unit content. The Early Feedback Task in this unit is a multiple-choice online assessment drawing on assumed knowledge and materials from Day 1. The task will be available on Canvas from 27 August 9.00am to 11.59pm 2026, Sydney Australia time. Students will be provided with immediate automated feedback upon completion of the task.

Structured class participation (10%): Students will lead the class discussion for one session. This will be allocated prior to the commencement of the unit and the allocated student is required to lead the class discussion under the lecturer's questioning. They will be assessed against the Class Participation Assessment Rubric.
Students who are unable to make their allocated class must apply for Special Consideration. A failure to lead the class discussion in the allocated class will result in 0/10 for this assessment and may lead to an Absent Fail grade.
The outcome of a successful special consideration application is an alternative assessment, such as a viva voce (oral test), that has been designed to meet the same learning outcomes. 

In-class test (30%): The test will begin at 10am on 10 September 2026 Sydney, Australia time. It will be an open book test (hard copy/printed materials only, no electronic devices) in the form of problem style questions. It is a handwritten pen and paper test. You will have 1 hour of writing time plus 15 minutes of reading time to prepare your responses. The outcome of a successful special consideration application is a replacement test. The replacement test may be delivered via an alternative assessment, such as a viva voce (oral test), that has been designed to meet the same learning outcomes as the original test. The format of the alternative assessment will be determined by the unit coordinator.

Final exam (60%): The Final Exam will be held on-campus and supervised. It will be an open book exam (hard copy/printed materials only, no electronic devices) in the form of problem style questions. You will have 2 hours of writing time plus 30 minutes of reading time to prepare your responses. The outcome of a successful special consideration application is a replacement test that may be delivered via an alternative assessment, such as a viva voce (oral test), that has been designed to meet the same learning outcomes as the original test. The format of the alternative assessment will be determined by the unit coordinator.

The supervised final exam will be held on campus during the week beginning Monday, 12 October 2026. The exam timetable will be released by the Exams Office in due course. For further information, please refer to Exam Timetables

 

Alternative Capstone proposal and essay: LLM students who are undertaking this unit towards the end of their degree, and need a capstone experience to complete their degree, must apply to the unit coordinator to undertake the assessment option of a Capstone Essay.

Students wishing to take up this option are required to submit a 500-word topic proposal via Canvas by 11.59pm on 20 August 2026 Sydney, Australia time. 

Your essay topic should respond to the material covered in the present unit. However, at the same time, in order to serve as a capstone for your LLM, it should build upon the learning that has taken place during your LLM studies more generally. 

The Capstone Essay will replace the final exam which is worth 60% of your marks for the unit. The Capstone Essay must be 7000 words and is due at 11.59pm 12 October 2026 Sydney, Australia time.

An oral defence of the Capstone will be held within two weeks of submission. The final mark will be determined taking into account both the written material and the oral defence.

The total word count for the Capstone essay will include all headings, footnotes and any bibliography etc, and exclude acknowledgements of assistance from editors, automated writing tools or generative AI.  No penalty will apply if you exceed the word limit but any words beyond this limit will NOT be read or marked.

Referencing: The Sydney Law School expects you to use the Australian Guide to Legal Citation (4th edition, 2018) for your footnoting style, although you should confirm this with your lecturer. A link to the library website where this is set out comprehensively is available at Referencing and Citation Styles: AGLC4. 

 

Special consideration: Successful grants of Special Consideration may involve alternative tasks, as appropriate.  

Assessment requirements to pass a unit of study: A student must make a genuine attempt at all assessment tasks set out in this Unit of Study in order to obtain a Pass mark and grade (or above); otherwise an Absent Fail grade will be recorded as the student’s result for this Unit of Study. As the EFT is an early diagnostic tool, this task is not included in the final grade for the unit.

Use of generative artificial intelligence (AI)

You can use generative AI tools for open assessments. Restrictions on AI use apply to secure, supervised assessments used to confirm if students have met specific learning outcomes.

Refer to the assessment table above to see if AI is allowed, for assessments in this unit and check Canvas for full instructions on assessment tasks and AI use.

If you use AI, you must always acknowledge it. Misusing AI may lead to a breach of the Academic Integrity Policy.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

Late penalties do not apply to exams and tests. Capstone essay: The late submission of a piece of assessment, without an approved extension, will attract a penalty of 10% of the total marks available for the piece of assessment per 24 hours or part thereof, after the due time on the due date.

Academic integrity

The University expects students to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

Our website provides information on academic integrity and the resources available to all students. This includes advice on how to avoid common breaches of academic integrity. Ensure that you have completed the Academic Honesty Education Module (AHEM) which is mandatory for all commencing coursework students

Penalties for serious breaches can significantly impact your studies and your career after graduation. It is important that you speak with your unit coordinator if you need help with completing assessments.

Visit the Current Students website for more information on AI in assessments, including details on how to acknowledge its use.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.
