Oladiwura Eyitayo Oyesode

Wura Eyitayo (Doctoral candidate at Schulich School of Law, Dalhousie University)

I grew up in Nigeria inspired by my father’s career as a lawyer. Years later, I decided to follow in his footsteps. After earning my law degree from the University of Lagos in 2013, I practiced at two law firms in that city. I moved to Canada in 2016 to earn my master’s degree in Law. I am now in my fourth year as a PhD candidate at the Schulich School of Law, Dalhousie University. The aim of my research is to examine the nature of the tax treaty network of three African countries, namely Nigeria, Botswana, and Tanzania. Second, I examine the impact that these treaties have on tax revenue generation in the three countries. These questions will lead to my argument that the way these tax treaties are structured, they continue to impede tax revenue generation in the three African countries, which is a bane to the fulfilment of the Sustainable Development Goals (SDGs). A comparative analysis of the tax treaty networks which I will undertake will show if these countries have similar tax treaty provisions, the implications of these provisions on tax revenue generation, and possible recommendations on how the three countries can reform their tax treaties to increase tax revenue generation. The three countries are chosen to demonstrate similar challenges that impede tax revenue generation across the African continent, and how African countries can collectively change the story by reforming their tax treaties to reflect the changes proposed in my thesis. My goal is to help design effective and efficient international tax rules and policies for fostering inclusive growth and development in the three African countries and in other African countries as well.
