The Digital Economy, Global Tax Reforms and Developing Countries – An Evaluation of Pillar I and Art. 12B UN Model

  • By Jost Heckemeyer, Inga Schulz, Christoph Spengel, and Sarah Winter

This paper evaluates the Multilateral Convention to implement Pillar I Amount A, released by the OECD in October 2023, and the alternative proposal of Art. 12B for tax treaties suggested by the UN, with a particular emphasis on the perspective of developing countries. It provides a comparative analysis of the proposals using an integrated economic and legal approach. The assessment is based on the two proposals’ ability to generate tax revenue and their implications for net-importing countries. The legal analysis demonstrates significant differences between the two proposals in the implied reallocation of taxing rights, depending on the considered (digital) business model. The paper contends that overall and despite its complexity, Pillar I Amount A addresses the specific interests of developing countries better than Art. 12B UN Model. In particular, Pillar I Amount A will likely outperform the UN’s proposal in terms of its tax revenue potential.

Broader Border Taxes: A New Option for European Union Budget Resources

  • By Pascal Saint-Amans

The EU suffers from ‘tax leakage’ in which profits are shifted from high-tax to low-tax EU countries, and from there onto no or low-tax non-EU jurisdictions, often without the application of withholding taxes. So far, an opportunity for what could be seen as a tax at the border of the internal market, aiming to protect the market from harmful competition, may have been missed. Such a tax could reflect the undertaxed profit rule agreed as part of the international deal on the corporate minimum tax. Focusing on protecting the revenues of EU members by common tax borders could offer scope for new own resources.

Efficient Economic Rent Taxation Under a Global Minimum Corporate Tax

This IMF working paper highlights that the international agreement on a corporate minimum tax is a milestone in global corporate tax arrangements. The minimum tax disturbs the equivalence between otherwise equivalent forms of efficient economic rent taxation: cash-flow tax and allowance for corporate equity. This paper shows that the marginal effective tax rate initially declines as the statutory tax rate rises, reaching zero where the minimum tax is inapplicable and increases thereafter. The key insight is that a minimum tax, akin to Pillar Two, breaks the equivalence between cash-flow taxation and the allowance for corporate equity (ACE).

Location, Financial and Real Effects of CFC Rules after the ATAD Implementation in the EU

This paper investigates the introduction of Controlled Foreign Company (CFC) rules by the Anti-Tax Avoidance Directive (ATAD) in the European Union. The authors study whether the implementation of CFC rules, in the context of the ATAD, alters the location, financial, and economic activity decisions of multinational enterprises (MNEs). The results reveal that the newly implemented CFC rules are only partly effective in reducing profit shifting. Instead, the overall number of CFC subsidiaries decreased, and the financial revenue of the persisting subsidiaries remained largely unchanged. The authors observed positive effects on the costs of employees assigned to a CFC subsidiary, suggesting that the economic activity exemptions introduced by the ATAD allow MNEs to circumvent the rules. This permits them to opt for a simple approach, enhancing economic activity in these locations.

Business model digitalization, competition, and tax savings

The authors examine the effect of business model digitalization on competition and corporate tax savings. Global policymakers have expressed concern that digitalization-related tax savings unfairly benefit the competitive standing of rival firms over their competitors. This article argues that rivals’ adoption of a digital business model leads to negative economic effects on the performance of their non-digitalizing competitors. Contrary to policymakers’ concerns of digitalization-related tax savings unfairly shaping competition, the authors' findings suggest that tax savings from digitalization are not a key driver of altering competition between digitalized and non-digitalized firms.
