OECD Pillar Two – further guidance

Components of the Pillar Two rules

The OECD Inclusive Framework model rules apply to large multinational groups with annual consolidated group revenue of at least €750 million and have the following key components:

• An income inclusion rule (IIR) applies on a top-down basis such that tax due is (in most cases) calculated and paid by the ultimate parent entity to the tax authority in its country. The tax due is the ‘top-up’ amount needed to bring the overall tax on the profits in each country where the group operates up to the minimum effective tax rate of 15%.
• The undertaxed profits rule (UTPR, sometimes referenced as the undertaxed payments rule) will apply as a secondary (backstop) rule in cases where the effective tax rate in a country is below the minimum rate of 15%, but the income inclusion rule has not been fully applied. The top-up tax will be allocated to countries which have adopted the undertaxed profits rule based on a formula and is to be implemented by countries either by denial of a deduction for payments or by making an equivalent adjustment.
• The model rules also allow for countries to introduce a qualified domestic minimum top-up tax (QDMTT) aligned with Pillar Two. Under a QDMTT, top-up taxes in respect of any low-taxed profits of a group’s entities in that country are payable domestically, rather than to other countries under the income inclusion or undertaxed profits rules.

Further administrative guidance

The third set of administrative guidance has been released to further clarify the interpretation and operation of the model rules.

Transitional country-by-country reporting (CbC) safe harbour

The transitional CbC safe harbour uses information taken from a business’s CbC report and/or financial statements to exclude a group’s operations in lower-risk countries from the compliance obligation of preparing full Pillar Two calculations, for up to three years.

Further guidance is provided on the requirement that the business’s CbC report must be prepared and filed using qualified financial statements, including.

• Consistent use of data: All of the data used in the transitional CbC reporting safe harbour calculations for a country must come from the same qualified financial statements (i.e. consolidated financial statements of the ultimate parent entity or the separate financial statements of each group entity).
• Using different accounting standards: It is possible to use data from the consolidated financial statements of the ultimate parent entity for some countries and data from the separate financial statements of each group entity for other countries.
• Unless explicitly required, adjustments to qualified financial statement data are not permitted, even if the adjustments are intended to increase consistency with the Pillar Two rules.
• Groups in scope of the Pillar Two rules but not required to file CbC reports are eligible for the transitional CbC reporting safe harbour if they prepare calculations using data from qualified financial statements that would have been included in a CbC report.

The guidance also includes confirmation that the definition of ‘simplified covered taxes’ for the safe harbour’s simplified effective tax rate computation taken from qualified financial statements includes any adjustments for prior periods (but amounts in respect of any uncertain tax positions must be removed).

When calculating the routine profits test, the substance-based income exclusion amount should be calculated using the model rules’ transitional rate applicable for the period i.e. 9.8% for payroll and 7.8% for tangible assets in 2024.

An anti-avoidance rule will prevent the transitional CbC reporting safe harbour from applying if targeted ‘hybrid arbitrage arrangements’ (e.g. deduction/non-inclusion arrangements, duplicate loss arrangement, or duplicate tax recognition arrangements), are entered into after 15 December 2022 (or 18 December 2023 in some circumstances).

Purchase price accounting adjustments

Additional guidance has been issued regarding purchase price accounting adjustments in the context of the transitional CbC safe harbour. Adjustments to amounts reported in qualified financial statements are not generally permitted under the safe harbour. Specific rules will apply where purchase price accounting adjustments are allocated and incorporated into the financial accounts of an acquired group entity that are used in the preparation of the consolidated financial statements of the ultimate parent entity, or the separate financial statements of the group entity. In order to be considered ‘qualified financial statements’, a goodwill impairment adjustment must be made to add back the impairment if it relates to transactions entered into after 30 November 2021 and a consistent CbC reporting condition must also be met.

Consolidated revenue threshold

Further guidance has been provided on the meaning of revenue for the €750 million consolidated revenue threshold. Revenue includes the ‘inflow of economic benefits from the group’s ordinary activities reflected in the profit and loss statement of the ultimate parent entity’s consolidated financial statements. Ancillary interest income outside of a group’s ordinary activities is not included in revenues, whereas interest would be included if a business offers customer loans as part of its ordinary business and reports interest income in net revenues in the profit and loss statement. 

Revenues are determined in line with the relevant accounting standard, which may allow for netting for discounts, returns and allowances. If different types of revenue are separately presented, they must be aggregated. Revenue includes both realised and unrealised net gains from investments reflected in the profit and loss statement of the ultimate parent entity’s consolidated financial statements, as well as income or net gains separately presented as extraordinary or non-recurring items. Adjustments can be made for investment losses if they are shown separately from investment gains in the consolidated financial statements to align with net treatment.

Where a financial entity does not record gross amounts from transactions in its financial statements, the items considered similar to revenue under the accounting standards of the ultimate parent entity should be used e.g. ‘net banking product’ or ‘net revenues’. For example, for a financial entity, revenue includes the net amount of income/gains from a financial transaction such as an interest swap.

Mismatches between financial reporting years

Where there is a mismatch between the financial reporting year of the ultimate parent entity and another group entity, the Pillar Two rules follow the approach taken in the ultimate parent entity’s consolidated financial statements. Similarly, where there is a mismatch between the taxable period of a group entity and the financial reporting year of the multinational group, the group entity should apply the approach used in the ultimate parent entity’s consolidated financial statements to determine its adjusted covered taxes for the year.

Allocation of blended CFC taxes

Administrative guidance was released in February 2023 on allocating blended CFC taxes (such as US GILTI) to group entities for the purposes of the Pillar Two calculations using a formulaic approach based on ‘blended CFC allocation keys’. Further guidance has now been released, including clarification that where multiple jurisdictional ETRs are computed for a country (e.g. because a separate ETR calculation has been required for an investment entity) the allocation key for an entity is calculated using the jurisdictional ETR applicable to the blending group to which that entity belongs. Guidance is also provided on how to calculate the blended CFC allocation key if there is no other requirement to calculate an ETR for the country e.g. the simplified ETR calculation should be used where an election has been made to use the transitional CbC reporting safe harbour. Guidance is also provided in respect of the allocation of blended CFC taxes to entities that are not group members (or joint ventures) for Pillar Two purposes.

Administrative relief for groups with short reporting years

For groups with a short reporting year the due date for compliance and filing obligations will not be before 30 June 2026 (the earliest filing date for groups with full reporting years).

Simplified calculation safe harbour for non-material constituent entities

The guidance includes a permanent simplified calculation safe harbour for non-material constituent entities (‘NMCEs’). Broadly, an NMCE is an entity that is not consolidated in the ultimate parent entity’s consolidated financial statements solely on size or materiality grounds but is still considered a ‘constituent entity’ for Pillar Two purposes. A number of conditions must be met in relation to the NMCE, including that the ultimate parent entity’s consolidated financial statements have been externally audited. An annual election is required for each individual NMCE.

Under the safe harbour, groups can use CbC reporting information for an NMCE to determine whether the country where the NMCE is located meets one or more of the routine profits, de minimis, or effective tax rate tests such that the top-up tax for the country is deemed to be zero. The safe harbour uses ‘total revenue’ and ‘accrued income tax (current year)’ (with no deferred tax) as used for CbC reports as a proxy for the NMCE’s profit and covered taxes respectively.

Next steps

The OECD Inclusive Framework will continue to release further agreed guidance on an ongoing basis. Guidance is expected to be released in the first half of 2024, including on the application of deferred tax liability recapture rules and the allocation of deferred taxes to other constituent entities (e.g. in relation to CFC regimes or permanent establishments). A government peer review process will also be implemented to monitor countries’ implementation of the Pillar Two rules, and work will continue on the Pillar Two administrative framework and dispute resolution mechanisms.

The administrative guidance will be incorporated into a revised version of the Commentary to the Pillar Two Model Rules to be released in 2024.

Countries are in the process of implementing the Pillar Two model rules in their domestic legislation. IIRs and QDMTTs will begin to apply from 2024 in some countries, with UTPRs starting to apply from 2025.
