On 20 December 2021, the OECD / G20 Inclusive Framework on BEPS involving 137 countries issued detailed rules for the Pillar Two global minimum effective tax rate of 15%. This is a major milestone in the OECD / G20’s initiatives to address perceived tax challenges arising from the digitalisation of the economy. The release contains the details on how to calculate the minimum effective tax rate under the Global Anti-Base Erosion (GloBE) rules and targets 2023 for implementation.
The minimum effective tax rate and how it is calculated is one element of the Pillar Two GloBE plan. The actions to take if profits are not taxed in the home country at an effective rate of at least 15% is another element of Pillar Two. Excluded from the OECD release were details on the Subject to Tax Rule (STTR). The STTR provides for withholding tax on payments included on a defined list (e.g., interest, royalties), from developing countries. Details on this rule are expected to be released in early 2022.
As expected, details pertaining to Pillar One, which provides for the reallocation of taxing rights to market jurisdictions for certain groups with turnover of greater than €20bn, were not published at this time. Again, these are expected to be released in 2022.
The EU intends to implement the Pillar Two measures by way of a Directive. The European Commission formally confirmed this on 22 December 2021. It is this Directive which, if it enters into force, will ultimately be transposed into Irish domestic legislation. The Commission has stated that the Directive should align closely with the BEPS Pillar Two plan with one important exception, extending the 15% minimum effective tax rate rules to groups that meet the €750 million revenue threshold but have purely domestic operations, i.e. do not have any foreign operations. This extension of the rules is required to ensure the Directive complies with the fundamental freedoms afforded to taxpayers under the Treaty on the Functioning of the European Union, notably the Freedom of Establishment.
