This course is available on the Executive LLM. This course is not available as an outside option.

Course content

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 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 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.


The module will provide between 24 and 26 hours of contact teaching time. Students will be provided with online and hard copy materials for the module well in advance of the intensive teaching. The teaching will take place in week-long sessions, which will typically be held in the first half of September, December and April. Where there is student demand we will also offer modules taught over two intensive weekends. For the week-long sessions, the module will run from either Monday to Friday, or Sunday until Friday with a rest day on Wednesday.

Formative coursework

Students will have the option of producing a formative exam question of 2000 words to be delivered one month from the end of the module’s teaching session by email.
