Georgia Law Professor Assaf Harpaz presents at International Roundtable on Taxation and Tax Policy

University of Georgia School of Law professor Assaf Harpaz presented his draft paper “Global Tax Wars and the Shift to Source-Based Taxation” and chaired the “Jurisprudence and Enforcement” panel at the 8th International Roundtable On Taxation And Tax Policy during July.

Below is an abstract from the draft paper:

Current debates in international taxation frequently engage with the concept of global tax fairness, relating to the equitable allocation of taxing rights between jurisdictions. These questions emerge within an international tax framework at a critical juncture. In a rapidly evolving digital economy, intergovernmental organizations are battling to shape the cross-border tax agenda. Global North economies have dominated this regime through the Organisation for Economic Co-operation and Development (OECD), which has drawn backlash due to its undemocratic procedure and unfavorable outcomes for developing countries. Meanwhile, the United Nations has occupied a relatively peripheral role in global tax governance. However, its role could change with the establishment of a new Framework Convention on International Tax Cooperation – an initiative overwhelmingly supported by the world’s developing countries.

The article conceptualizes the contemporary international tax discourse as “tax wars,” contrasting the taxing powers and interests of the OECD-led Global North with those of the UN-backed Global South. It explores the standards and preferences that have underpinned the regime since its inception, focusing on residence and source taxation. The article argues for a shift towards source-based taxation, drawing on procedural and distributive justice principles. To do so, the article proposes expanding the permanent establishment standard in model treaty language, creating an opportunity for broader taxation of business profits in the source country. This transition will address longstanding disparities and is increasingly warranted in a digital economy that does not rely on physical presence.

Assaf Harpaz joined University of Georgia School of Law as an assistant professor in summer 2024 and will teach classes in federal income tax and business taxation. Harpaz’s scholarly focus lies in international taxation, with an emphasis on the intersection of taxation and digitalization. He explores the tax challenges of the digital economy and the ways to adapt 20th-century tax laws to modern business practices.
