Introduction
The concept of adjusted covered taxes under Pillar 2 of the OECD’s global minimum tax framework has become a pivotal topic in international tax compliance. As corporations navigate evolving regulations, understanding the computation, implications, and adjustments of covered taxes is crucial. In this article, I break down the intricacies of adjusted covered taxes, provide illustrative examples, and discuss the broader economic implications.

Understanding Pillar 2 and the Global Minimum Tax
Pillar 2, part of the OECD/G20 Inclusive Framework, establishes a global minimum tax of 15% on large multinational enterprises (MNEs). This framework aims to curb profit shifting and ensure fair tax contributions across jurisdictions. The central mechanism, known as the Global Anti-Base Erosion (GloBE) rules, determines an MNE’s effective tax rate (ETR) and mandates additional top-up taxes if the ETR falls below the 15% threshold.
What Are Covered Taxes?
Covered taxes refer to income taxes imposed on corporate profits, including:
- Corporate income tax (CIT)
- Withholding taxes on profits
- Certain tax adjustments related to deferred tax accounting
Adjustments to these taxes influence the final ETR calculation, impacting whether a jurisdiction is subject to top-up taxes.
Adjustments to Covered Taxes
Adjusted covered taxes incorporate specific modifications to ensure accurate ETR calculations. The primary adjustments include:
- Deferred Tax Adjustments: Certain deferred tax assets (DTAs) and liabilities (DTLs) are included in covered taxes to reflect the long-term impact of tax provisions.
- Non-Income Tax Exclusions: Taxes unrelated to corporate profits, such as sales tax and payroll taxes, are excluded.
- Tax Refunds and Credits: Refundable tax credits reduce covered taxes, while non-refundable credits generally do not.
- Temporary Differences Adjustments: Certain temporary book-tax differences are adjusted to align tax computations with economic profit reporting.
Deferred Tax Adjustments
A key aspect of adjusted covered taxes is the treatment of deferred tax assets and liabilities. The OECD framework incorporates a specific methodology for recognizing deferred tax items at a standardized 15% rate.
Example: Suppose a corporation records a deferred tax liability (DTL) of $100 million due to accelerated depreciation. Under Pillar 2 rules, the liability is adjusted based on the 15% minimum tax rate:
\text{Adjusted DTL} = \frac{100 \text{ million} \times 15\%}{\text{Statutory Tax Rate}}If the statutory tax rate is 25%, the adjusted DTL becomes:
\frac{100 \times 15}{25} = 60 \text{ million}This adjustment ensures consistency across jurisdictions with varying tax rates.
Illustrative Table: Covered vs. Adjusted Covered Taxes
| Category | Included in Covered Taxes? | Adjusted for ETR? |
|---|---|---|
| Corporate Income Tax | Yes | No |
| Withholding Tax on Profits | Yes | No |
| Deferred Tax Liabilities | No | Yes |
| Non-Income Taxes | No | No |
| Refundable Tax Credits | No | Yes |
| Non-Refundable Tax Credits | No | No |
Effective Tax Rate (ETR) Computation
The ETR under Pillar 2 is calculated as follows: E
\text{ETR} = \frac{\text{Adjusted Covered Taxes}}{\text{GloBE Income}}Where:
- Adjusted Covered Taxes include modifications discussed earlier.
- GloBE Income represents net profit adjusted for permanent and temporary tax differences.
Example of ETR Calculation
Assume a company has:
- Covered taxes: $200 million
- Deferred tax adjustments: $50 million increase
- GloBE Income: $2 billion
Applying the formula:
\text{ETR} = \frac{200 + 50}{2000} = \frac{250}{2000} = 12.5\%Since 12.5% is below the 15% threshold, the company faces a top-up tax to reach the minimum.
Impact on US Multinationals
For US-based MNEs, adjusted covered taxes impact compliance and tax planning strategies. Key considerations include:
- Interaction with GILTI (Global Intangible Low-Taxed Income): The US GILTI regime already imposes a global minimum tax, potentially reducing additional Pillar 2 liabilities.
- Foreign Tax Credit (FTC) Limitations: FTC rules affect how MNEs credit foreign paid taxes against US tax liabilities.
- Book-Tax Conformity Adjustments: US GAAP-based book-tax differences may necessitate additional reconciliations under Pillar 2.
Strategic Responses
US corporations must adapt to these rules through:
- Proactive ETR Management: Monitoring tax positions to ensure compliance while optimizing tax efficiency.
- Deferred Tax Planning: Aligning deferred tax positions with Pillar 2 methodologies.
- Jurisdictional Tax Modeling: Conducting scenario analyses to predict Pillar 2 impacts across multiple tax jurisdictions.
Conclusion
Adjusted covered taxes under Pillar 2 play a crucial role in determining global tax liabilities for MNEs. By understanding these adjustments, corporations can better navigate compliance requirements and mitigate risks. As implementation progresses, staying informed on OECD guidance and regulatory updates remains essential.
