G7 Eases Application of Pillar 2: Challenges for Transfer Pricing Policies

The recent G7 agreement introduces a “side-by-side” approach for Pillar 2 of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS), allowing countries to apply their own national rules if they are equivalent to the global minimum tax rules. This decision could delay the uniform application of the 15% minimum tax and increases complexity for multinational groups.

Background

The 2021 agreement, reached by more than 140 countries under the auspices of the OECD, consisted of two pillars:

  • Pillar 1: Redefine taxing rights for large multinational corporations (with particular focus on digital giants) based on the location of their consumers, not only where the company is headquartered.
  • Pillar 2: Introduce a global minimum effective tax rate of 15% for multinational groups with revenues exceeding €750 million, to prevent a race to the bottom in tax rates.

The G7 agreement adopts the new “side-by-side” approach, which allows countries like the United States to apply their own domestic rules to tax their multinationals (instead of other countries applying compensatory adjustments, known as “top-up taxes”), provided that these rules are considered “equivalent” to Pillar 2.

This has been driven mainly by the U.S., which seeks to have its tax regime (specifically GILTI, Global Intangible Low-Taxed Income) recognized as compliant with Pillar 2, thus preventing U.S. companies' subsidiaries in Europe from facing additional taxes.

The essence of Pillar 2 is to discourage profit shifting to low-tax jurisdictions. However, this agreement reduces international pressure for a uniform standard and opens the door to national interpretations.

In practice, this means there may be differences in how each country defines an effective minimum tax, increasing complexity for multinationals needing to align their transfer pricing policies with the realities of each jurisdiction.

Impact on Transfer Pricing

This new scenario presents several challenges and opportunities for multinational companies:

  • Review of tax structures: Companies will need to assess whether their current structures remain efficient under the new system and consider potential reorganizations to optimize their tax burden.
  • Alignment with economic substance: Transfer pricing policies must reflect the economic reality of operations, especially in jurisdictions with tax regimes deemed equivalent. This is particularly relevant in countries like Spain, which strongly support Pillar 2 and will seek to secure additional tax revenues.
  • Increased complexity and regulatory divergence: With national “equivalent” regimes and Pillar 2 rules coexisting, multinationals will face differences in how the minimum tax is calculated across jurisdictions, potentially leading to inconsistencies in their transfer pricing analyses.
  • Greater scrutiny and control by tax authorities: Countries that strongly support Pillar 2, such as Spain and other European jurisdictions, may strengthen their audit programs and intragroup transaction reviews to ensure no erosion of the taxable base occurs.
  • Documentation and compliance: The coexistence of national and international rules will require greater diligence in transfer pricing documentation and compliance, to avoid double taxation risks or penalties.
