For inclusion in Finance Bill 2022/23, the United Kingdom has released draft legislation to introduce the OECD’s Pillar Two Model Rules into UK law. The draft legislation includes an Income Inclusion Rule (IIR), to be known in the UK as the Multinational Top-up Tax, which will apply to accounting periods beginning on or after December 31, 2023. The UK government also stated its intention to introduce an Undertaxed Profit Rule (UTPR), although the final decision on its timing will be confirmed at a later date. The overall approach to drafting the legislation has been to closely follow the intent of the Model Rules, while also adapting the structure and drafting in places to achieve clarity. Noted below are a few areas where the draft legislation potentially differs from the Model Rules or the associated commentary.
Actions to consider: Although further changes may be made to the UK Pillar Two rules, the draft legislation provides an opportunity to assess the impact and prepare a roadmap to be Pillar Two ready. Also note that transitional rules will apply to transactions undertaken now and therefore the draft legislation should be considered as part of any analysis relating to current transactions.
As part of the summary of responses to the original Pillar Two consultation, the government believes there are strong arguments in favor of the introduction of a UK Domestic Minimum Tax (DMT), to ensure the UK Exchequer receives any additional tax arising from Pillar Two on UK economic activities. The government will continue to consider the introduction of a DMT and envisages that, if introduced: the threshold would be €750m to mirror the Pillar Two rules; and it would apply to both UK-headed and foreign-headed groups. It will also consider the costs and merits of applying it to wholly domestic groups to prevent economic distortions.
While the draft legislation provides additional certainty as to the application of the IIR, the government believes that there are several issues that should be addressed within the context of Administrative Guidance as part of the OECD Implementation Framework (IF). Examples of issues that the IF should address include:
Addressing these issues at an international level would promote consistency across implementing jurisdictions and the reduction of risks for disputes and uncertainty. The government subsequently notes that it will remain open to resolving some issues domestically in order to avoid disproportionate and unintended outcomes, provided that this does not challenge the common approach, produce risks to the Exchequer, or risk double taxation to business.
While the draft UK legislation closely follows the intent of the Model Rules, there are some areas where the legislation could be interpreted to differ, in particular by reference to the Commentary associated with the Model Rules. For example:
HM Treasury addressed the relationship between the IIR and GILTI in their response to the previous UK consultation as part of the draft legislation release. It notes that if GILTI is not changed, the United Kingdom is ready to recognize GILTI as a CFC rule with payments under GILTI to be taken into account as part of the Adjusted Covered Taxes under GLoBE. Although this is welcome news, there are still important technical issues to address regarding the calculation of US taxes paid under GILTI and their allocation amongst Constituent Entities.
The government has invited feedback on the draft legislation and also welcome continued engagement with stakeholders. Comments on the draft legislation are due by September 14, 2022 to inform the final drafting of the legislation.
Although further changes may be made to the UK Pillar Two rules, MNEs should assess the impact, prepare a roadmap to be Pillar Two ready and engage with the relevant stakeholders in their organizations to get their buy-in and support for the required resources. Set out below are key issues to get ‘Pillar Two ready, along with reasons why MNEs should start preparing sooner rather than later.
Note that the draft legislation (in line with the Model Rules) contains transitional rules. These apply to transactions undertaken now and can impact the Pillar Two position for groups once the rules are in place (effective January 1, 2024). Therefore MNEs should factor the draft legislation into the consideration of any current transactions.
