Digital Services Taxes and Trade Law Conflicts

The rapid growth of the digital economy has revealed significant structural limitations within traditional international tax frameworks. Multinational digital enterprises are capable of generating considerable revenue in jurisdictions where they maintain little or no physical presence, thereby minimizing their exposure to corporate taxation. In response to this challenge, several countries have introduced Digital Services Taxes (DSTs), which are designed to tax revenues generated by large digital platforms operating within their domestic markets. Although these taxes seek to restore fairness in international taxation, they have also provoked considerable legal debate, particularly concerning their compatibility with international trade law. This study explores whether unilateral DSTs may function as trade barriers and whether they contravene non-discrimination principles within the multilateral trading system. By examining the legal framework of the World Trade Organization, especially obligations arising under the General Agreement on Trade in Services and the General Agreement on Tariffs and Trade, the paper analyzes the tension between national fiscal sovereignty and international trade regulations. It contends that while DSTs are not inherently inconsistent with WTO law, poorly structured unilateral measures may risk violating non-discrimination obligations and provoking trade disputes.
