Dr Michael Blackwell (NAB 7.21)

This course is available on the LLM (extended part-time), LLM (full-time), MSc in Regulation and University of Pennsylvania Law School LLM Visiting Students. This course is available as an outside option to students on other programmes where regulations permit.

This course has a limited number of places and we cannot guarantee all students will get a place.

This course will provide a comprehensive overview of the phenomenon of tax avoidance and of the attempts by states to combat it: both unilaterally and multilaterally. Whilst using examples predominantly from the UK, Australia and USA the issues addressed by the course are general across many jurisdictions and so will be applicable to those with interests beyond the UK, Australia and USA. 

The course will be multi-disciplinary, in that the course will draw on accessible social-science literature.

Taxpayers have always sought to minimise their tax burden. However recent decades have witnessed a sharp rise in popular and governmental concern with tax shelters and other tax avoidance. Traditional strategies of tax avoidance have included postponement of taxes and tax arbitrage, in addition to attempting to exploit ‘loopholes’ through a formalist interpretation of legislation. In recent years the proliferation of complex financial instruments has increased the opportunities for such avoidance. Additionally, globalisation and the development of the digital economy have facilitated tax avoidance strategies of base erosion and profit shifting (BEPS). This rise in opportunities for tax avoidance has been accompanied by an increased public concern that individuals and companies pay their ‘fair share’ of taxation: which states have responded to both through unilateral and multilateral actions (including the OECD’s project on BEPS and the EU’s Anti Tax Avoidance Package).

Particular topics covered will include (i) defining avoidance; (ii) strategies of tax avoidance; (iii) statutory interpretation and judicial approaches to tax avoidance especially with reference to the UK and USA; (iv) General Anti-Abuse and Anti-Avoidance Rules and Specific and Targeted Anti-Avoidance Rules; (v) reporting rules and other policies to deter avoidance; (vi) BEPS and the EU; and (vii) corporate social responsibility, professional ethics and public attitudes with regard tax avoidance.

This course will have two hours of teaching content each week in Michaelmas Term, either in the form of a two hour seminar or an online lecture and one hour class. There will be a Reading Week in Week 6 of Michaelmas Term.

Students should submit a detailed essay plan and working bibliography for the assessed essay. All students are expected to contribute to a series of class and online exercises and act as either a presenter or discussant during seminars.
