Unit
- Policy impetus: Pillar Two addresses the base erosion and profit shifting (BEPS) problem by ensuring large multinational enterprises pay a minimum level of tax on income earned in each jurisdiction, regardless of where they are headquartered.
- OECD framework: Developed by the OECD/G20 Inclusive Framework, Pillar Two comprises the GloBE (Global Anti-Base Erosion) rules, which include the Income Inclusion Rule (IIR) and the Undertaxed Payment Rule (UTPR).
- Minimum tax rate: The rules establish a global minimum effective tax rate of 15%, applied on a jurisdictional basis, to discourage profit shifting to low-tax jurisdictions and create a level playing field.
- Key stakeholders: Over 140 jurisdictions have agreed to the Pillar Two framework, with implementation progressing through domestic legislation in major economies including the EU, UK, Japan, South Korea, and others.
- Compliance scope: Pillar Two applies to multinational groups with consolidated annual revenue of EUR 750 million or more in at least two of the four preceding fiscal years.
- Interaction with BEPS 1.0: Pillar Two complements BEPS actions 5-14 by targeting remaining tax avoidance opportunities, particularly through low-taxed intangible profits and aggressive transfer pricing.
- Economic impact: Estimates suggest Pillar Two could increase global corporate tax revenues by $150-200 billion annually, while also reducing tax competition among jurisdictions.
- Transition timeline: The rules began to take effect in 2024 for some jurisdictions, with full implementation expected by 2025-2026, including transitional safe harbors for early compliance.
- Safe harbors and transitional rules: The OECD introduced transitional safe harbors to ease compliance during early years, including the CFC test, routine profits test, and simplified ETR test. These allow MNE groups to avoid detailed calculations if they meet certain low-risk criteria, reducing administrative burden.
- Substance based income exclusion: To preserve real economic activities, the GloBE rules exclude a portion of tangible assets and payroll costs from the ETR calculation. This exclusion starts at 8% of tangible assets and 10% of payroll, declining over ten years, ensuring that routine activities are not subject to top-up tax.
- Qualified domestic minimum top up tax (QDMTT): Jurisdictions may implement a QDMTT, which allows them to collect the top-up tax locally rather than ceding it to foreign parent jurisdictions. This preserves tax sovereignty and simplifies compliance for MNE groups operating in multiple countries.
Financial Formula
GloBE Effective Tax Rate (ETR)
ETR = Adjusted Covered Taxes / GloBE Income
ETR = Adjusted Covered Taxes / GloBE Income
Where:
- Adjusted Covered Taxes: Sum of current and deferred tax expenses adjusted for items such as excluded taxes, refundable credits, and amounts under appeal.
- GloBE Income: Financial accounting net income of the constituent entities in a jurisdiction, adjusted for certain exclusions and accruals.
- Result: A percentage rate that is compared to the 15% minimum; if below, a top-up tax is due.
Regulatory Requirement
Regulation: OECD/G20 Inclusive Framework on BEPS - Pillar Two Model Rules (2021, updated 2023)
The Model Rules provide the architecture for domestic implementation. Jurisdictions must adopt these rules into local law, and multinationals must comply with reporting and payment obligations. Key requirements include identifying the ultimate parent entity, calculating jurisdictional ETRs, and filing GloBE information returns.
