International Roundtable "Compliance, Avoidance, and Evasion in Taxation: The Role of Professionals - The Gray Area (Part 1)"

We are delighted to invite you to the first part of the event “Compliance, Avoidance, and Evasion in Taxation: The Role of Professionals - The Gray Area”, which is entitled "At the Crossroads of Tax Practices: Ethical Challenges and Democratic Issues". The event, which will be held on Zoom on the 8th of September 2023 from 3:30 pm BST (10:30 am EDT), is a collaborative endeavor, co-hosted by Manchester Law School, Boston College Law School, and the Corporate Crime Observatory (CCO) and co-organized by Prof. Diane Ring (BC Law), Dr. Costantino Grasso (Manchester Law School), and Dr. Donato Vozza (University of Roehampton).

This first part aims to engage in a comprehensive examination of the ambiguous domain known as the "gray area" in taxation, a realm where taxpayers' actions oscillate between legality and illegality. The discussion will delve into how tax professionals facilitate various forms of tax abuse, such as aggressive tax strategies and the creation of shell entities while operating in this nebulous zone. A significant focus will be placed on the ethical dimensions and varying loyalties of tax professionals, scrutinizing how their allegiance to clients can sometimes conflict with their responsibilities to the state and society at large, thereby posing risks to democratic values and the rule of law. Furthermore, the event will explore the organizational structures and profit motives that shape the tax profession, questioning the ethical underpinnings and conflicts of interest inherent in the industry. Lastly, the roundtable will address educational and ethical responsibilities in the fields of law, business, and taxation.
