After several years of meandering discussions, in 2019 the OECD moved forwards with two pillars of a long-term solution for the taxation of digital businesses.
Pillar 1 looks at when a taxable presence could be created in a market jurisdiction where there would not otherwise be one e.g. because there is no physical presence in that jurisdiction and considers the allocation of taxing rights to market jurisdictions and the interaction with existing transfer pricing rules.
Pillar 2 is concerned with having an overall minimum level of taxation for large digital businesses that operate globally. This minimum tax could be achieved in a number of ways including allowing jurisdictions to tax 'undertaxed' amounts and/or imposing withholding taxes on payments that would otherwise be 'undertaxed'. However, the thinking around this pillar is less developed than under pillar 1.
How would digital businesses be taxed under Pillar 1?
The OECD's proposed method of taxing digital businesses is much wider in scope than the UK's DST. The Pillar 1 proposal would apply to businesses providing automated digital services and "consumer-facing businesses" (businesses that generate revenue from supplying consumer products). This could catch large retailers, although the OECD is exploring whether a higher threshold of activity in market jurisdictions should apply to retailers. Carve-outs and financial thresholds are expected to be included.
A new nexus rule would apply when in-scope taxpayers have a "sustained and significant involvement" in the economy of a market jurisdiction. New complex profit allocation rules would allocate a proportion of the taxpayer's profits to market jurisdictions.
The OECD's goal is to arrive at a consensus solution by the end of 2020. On 31 January 2020, the OECD reported that the 137 countries involved in negotiating the measures had agreed to move ahead with the two pillar solution. However, a lot of work will be required to arrive at an agreed detailed set of rules, especially given that the United States has expressed serious concerns with Pillar 1.
