Understanding the Compliance Implications of the OECD’s Global Minimum Tax

As companies expand their operations to new countries and geographies, it brings new complications, especially from a taxation perspective. To woo multinationals and boost their respective economies, some countries offer extremely low levels of corporate taxation, which affects other countries, creating an imbalance in the global economy. To avoid this unfair advantage to any region or country, the Organization for Economic Co-operation and Development (OECD) has created a Global Minimum Tax. This initiative addresses the complexities and loopholes in international tax systems that have allowed Multinational Corporations (MNCs) to minimize their tax obligations. Businesses operating on a global scale must understand these compliance implications.

Background of the OECD’s Global Minimum Tax

The OECD’s Global Minimum Tax is part of the organization’s broader effort to combat tax Base Erosion and Profit Shifting (BEPS). BEPS refers to strategies that MNCs use to shift profits from high-tax jurisdictions to low-tax ones, thereby reducing their overall tax burden. The OECD, in collaboration with G20 countries, developed the BEPS Action Plan, which includes 15 actions to ensure that profits are taxed where economic activities generating those profits are performed.

One of the most important outcomes of the BEPS project is the development of the Global Minimum Tax, formerly known as Pillar Two. This measure establishes a minimum Effective Tax Rate (ETR) of 15% for MNCs with annual revenues exceeding €750 million. If a company’s profits are taxed at a lower rate in any jurisdiction, the home country of the parent company can impose an additional tax to bring the ETR up to 15%. This prevents companies from benefiting from tax havens with extremely low or zero tax rates.

Computation of Effective Tax Rate (ETR)

The ETR is calculated by aggregating the Global Anti-Base Erosion (GloBE) income or loss and the covered taxes of all constituent entities in a given jurisdiction. If the ETR falls below the 15% threshold, a top-up tax is triggered.

The top-up tax percentage is the difference between the 15% minimum rate and the calculated ETR in the jurisdiction. This percentage is then applied to the jurisdiction’s GloBE Income or Loss, after accounting for a substance-based income exclusion. The exclusion is based on a percentage of tangible assets and payroll expenses, designed to acknowledge the real economic activity within a jurisdiction.

Rule Order for Tax Liability

The OECD has established a clear hierarchy to determine which jurisdiction can collect the top-up tax:

• Qualified Domestic Minimum Top-Up Tax (QDMTT): The low-taxed jurisdiction where the income is earned has the primary right to impose the top-up tax.
• Income Inclusion Rule (IIR): If the low-tax jurisdiction does not implement a QDMTT, the top-up tax can be collected by the jurisdiction where the Ultimate Parent Entity (UPE) is located.
• Intermediate Parent Entity (IPE): If the UPE’s jurisdiction lacks a Qualified IIR, the tax can be imposed on the next entity in the ownership chain within a jurisdiction that has implemented an IIR.
• Undertaxed Payments Rule (UTPR): If none of the above rules apply, the remaining jurisdictions that have implemented UTPR can collect the tax, allocated based on a substance-based allocation key.

Coordinated Implementation

The GloBE rules require consistent implementation across jurisdictions to prevent double taxation and ensure predictability. While jurisdictions are not required to adopt these rules, those that do must implement them consistently with the agreed framework. Such measures guarantee a uniform application of the 15% minimum tax rate globally.

Now that you know how the Global Minimum Tax is computed, let’s explore its implications for organizations.

Implications for Organizations

This Global Minimum Tax impacts organizations across all sectors with a global presence, especially those that have moved a bulk of their operations to low or no-tax countries. Here’s a look at how it can impact existing operations and expansion plans.

Increased Compliance Burden

Global companies must now compute their ETR on a jurisdictional basis, which increases the complexity of tax reporting. Its financial team must understand local tax laws and align them with the OECD’s GloBE rules. This elaborate process could require additional time and resources.

Impact on Tax Planning Strategies

The Global Minimum Tax limits the effectiveness of traditional tax planning strategies, like shifting profits to low-tax jurisdictions. Companies may need to rethink their global tax structures to comply with the new requirements and avoid top-up taxes.

Risk of Double Taxation

Inconsistent implementation across jurisdictions could lead to double taxation. While the OECD’s framework aims to prevent this, the reality is that discrepancies in local law interpretations and applications could still result in companies being taxed twice on the same income.

Influence on Investment Decisions

The introduction of the Global Minimum Tax may influence where companies choose to invest. Jurisdictions with higher tax rates might become less attractive, leading companies to consider other factors, like the availability of tax incentives that are compliant with the GloBE rules.

Monitoring and Reporting Challenges

To comply with the new rules, companies will need to enhance their monitoring and reporting capabilities. This includes tracking income and taxes on a jurisdictional basis, which may require more investments in technology and expertise.

Navigating these implications requires a comprehensive understanding of the taxation structure, followed by strategic planning and implementation.

7 Best Practices for Complying with OECD’s Global Minimum Tax

To effectively meet the OECD’s Global Minimum Tax requirements, multinational enterprises should consider the following best practices:

1. Implement robust data management systems that can accurately track income, taxes, and substance-based income exclusions on a jurisdictional basis.
2. Conduct a comprehensive review of existing tax structures to identify potential risks of top-up taxes and explore opportunities for restructuring to optimize the global ETR.
3. Stay updated on developments in local tax laws and international tax frameworks.
4. Leverage technology solutions that can automate the calculation of ETR and top-up taxes, ensuring accuracy and efficiency in compliance efforts.
5. Work closely with tax advisors and legal experts specializing in international tax law to meet the Global Minimum Tax requirements.
6. Conduct scenario planning exercises to understand the potential impact of the Global Minimum Tax on various business operations and investment decisions. Accordingly, make proactive adjustments where needed.
7. With the increased scrutiny of global tax practices, prepare for audits and inquiries by tax authorities. Maintain transparent documentation and calculations to comply with GloBE rules.

Thus, these best practices can help organizations meet the OECD’s global minimum tax and avoid the penalties that come with non-compliance.

Key Takeaways

The OECD’s Global Minimum Tax is an important change in international taxation, with far-reaching implications for multinational enterprises. Understanding the detailed requirements and proactively adopting best practices can help global companies navigate the complexities of this new tax regime and mitigate potential risks. More importantly, companies must use this Global Minimum Tax as an opportunity to reassess global tax strategies and align them with evolving international standards.
