Young Ran (Christine) Kim (Utah) presented The Digital Services Tax: A Crossborder Variation of Consumption Tax Debate at the University of Vienna yesterday as part of its Faculty Workshop Series hosted by Sabine Kirchmayr-Schliesselberger (University of Vienna) and Neil Buchanan (Florida):
As highly digitalized business models, such as Google, Amazon, and Facebook, have been mainstreamed in the economy, the traditional profit allocation and nexus rules of taxation are further strained. Traditionally, profit is allocated to market countries when the business has physical presence there. However, highly digitalized business models can generate profits in market countries without physical presence. Thus, market countries, especially the EU, have started imposing a digital services tax (“DST”) on the gross revenue generated in jurisdictions with highly digital business models, which has ignited heated debate across the globe.
DST is criticized as “ring-fencing,” or segregating, certain digital business models, because it arguably imposes a disguised corporate income tax on the profits of only certain digital firms, which discriminates against American tech giants. However, while DST is politically driven, the criticism is largely based on practical concerns and focused on the imminent impact, such as who is the winner and loser in the short term, rather than considering DST theoretically. More importantly, there is little discussion of the consumption tax aspect of the DST. DST is a turnover tax, which is a subcategory of consumption tax levied on the gross revenue of a firm. However, strangely, there is little discussion of the theoretical value of DST as a consumption tax.
This article examines the policy debate on the recent legislative movement in the EU to adopt a DST, and then discusses whether it would be a new path towards a consumption tax in international taxation. The article further analyzes the tax incidence of DST as a consumption tax in the case of multi-sided digital platforms where a digital service provider, such as Amazon, interacts with multiple distinct user groups, such as user-buyers and user-sellers, that provide each other with network benefits. It then compares DST with other types of consumption tax, such as value added tax and destination-based cash flow tax. The article also considers whether the recent Supreme Court case of South Dakota v. Wayfair, discussing sales tax imposed on remote sellers, and subsequent state legislation on Netflix Tax may shed light on ways to overcome certain challenges DST faces.
