Global Minimum Tax (Pillar Two)

Global Minimum Tax (Pillar Two) is an international tax framework agreed by over 140 countries under the OECD and G20 Inclusive Framework, establishing a 15% minimum effective tax rate on profits earned by large multinational enterprise groups with annual consolidated revenues of at least 750 million euros.

Designed to curb base erosion and profit shifting, the framework ensures multinational enterprise (MNE) groups pay an agreed minimum tax rate in every jurisdiction where they operate. When a group's effective tax rate (ETR) in a country drops below 15%, the rules trigger a top-up tax to collect the difference. For corporate finance, treasury, and tax leaders in India, understanding Global Minimum Tax (Pillar Two) is essential for maintaining cross-border governance and avoiding double taxation.

How Global Minimum Tax (Pillar Two) Operates

The core engine of Pillar Two consists of the Global Anti-Base Erosion (GloBE) rules. These apply to constituent entities of MNE groups with annual consolidated group revenue of at least 750 million euros (around 6,750 crore Indian rupees) in at least two of the four preceding fiscal years. Excluded entities include government entities, international organisations, non-profit bodies, and qualifying investment or pension funds.

Unlike statutory headline rates, the GloBE effective tax rate is computed annually on a jurisdictional blending basis. All constituent entities in a single tax jurisdiction are aggregated. The calculation divides adjusted Covered Taxes by net GloBE Income for that jurisdiction. If this jurisdictional ETR falls below the 15% floor, a top-up tax percentage applies to the excess profits.

The Interlocking Charging Mechanisms

The GloBE framework uses an interlocking hierarchy of charging mechanisms to enforce the 15% rate floor across jurisdictions:

• Qualified Domestic Minimum Top-up Tax (QDMTT): Allows the source jurisdiction where undertaxed profits arise to levy the top-up tax first, preserving local tax sovereignty.
• Income Inclusion Rule (IIR): If the host country lacks a QDMTT, the ultimate parent entity pays the top-up tax in its home jurisdiction in proportion to its ownership interest in undertaxed foreign subsidiaries.
• Undertaxed Profits Rule (UTPR): Operates as a backstop. When undertaxed profits are not captured by a QDMTT or IIR, other group entities collect the tax through denied deductions or equivalent domestic adjustments.
• Subject to Tax Rule (STTR): A separate, treaty-based rule allowing developing source countries to impose gross withholding tax (up to a 9% minimum rate) on certain cross-border intragroup payments, including royalties and interest.

The rules also incorporate a Substance-based Income Exclusion (SBIE). This carve-out excludes a routine economic return from top-up tax, calculated from tangible asset values and eligible payroll costs in each jurisdiction.

The sequence below illustrates the collection hierarchy under the GloBE framework.

Impact on Indian Multinational Groups and Foreign Subsidiaries

India is an active member of the OECD and G20 Inclusive Framework. Domestically, the Income Tax Department administers corporate taxes where base corporate rates stand at 22% (effective 25.17% with surcharge and cess under Section 115BAA). Concessional rates exist for eligible manufacturing companies under Section 115BAB, and Minimum Alternate Tax (MAT) imposes an effective floor of approximately 17.47% on book profits.

While India's headline corporate tax rates generally exceed 15%, Pillar Two still directly impacts businesses across two primary channels:

Inbound Exposure for Foreign Multinationals in India

Foreign parent groups operating Indian subsidiaries or capability centres must evaluate whether local tax incentives lower their Indian GloBE ETR below 15%. Units operating under Special Economic Zone (SEZ) exemptions, within the International Financial Services Centre (IFSC at GIFT City), or claiming accelerated investment deductions can produce an effective tax rate below 15%. Without an Indian QDMTT, any top-up tax on these profits would be collected abroad by the parent jurisdiction under the IIR, effectively shifting domestic tax incentives to foreign treasuries.

Outbound Exposure for Indian Multinational Groups

Indian groups with global turnover exceeding 750 million euros must evaluate overseas entities. Operating marketing hubs, intellectual property holdings, or trading subsidiaries in low-tax jurisdictions exposes groups to top-up tax liabilities under foreign QDMTTs or the UTPR. When India enacts domestic GloBE legislation, Indian parent entities will become directly responsible for assessing and remitting top-up taxes under the IIR for their low-tax foreign subsidiaries.

Financial Reporting and Safe Harbours

Pillar Two requires extensive data compilation across international finance operations. Groups must submit the GloBE Information Return (GIR), which contains comprehensive data points covering constituent entities, intra-group transactions, and statutory adjustments.

To reduce compliance burdens during initial phases, the framework provides Transitional CbCR Safe Harbours based on qualified Country-by-Country Reporting data. A group can reduce top-up tax in a jurisdiction to zero if it satisfies any of three tests:

• De Minimis Test: Total revenue in the jurisdiction is under 10 million euros and profit before income tax is under 1 million euros.
• Simplified ETR Test: The simplified ETR equals or exceeds the transition rate (15% for 2024, 16% for 2025, and 17% for 2026).
• Routine Profits Test: The Substance-based Income Exclusion equals or exceeds jurisdictional pre-tax profit.

For corporate accounting, the Institute of Chartered Accountants of India (ICAI) and the Ministry of Corporate Affairs introduced amendments to Ind AS 12 (Income Taxes). These provide a mandatory temporary exception from recognising deferred taxes arising from Pillar Two, while mandating qualitative and quantitative disclosures in financial statements regarding potential exposures.

Worked Example: Calculating GloBE Top-Up Tax

Consider an Indian-parented group with consolidated annual revenues exceeding 750 million euros holding an operating subsidiary in Country X. Country X does not levy a QDMTT.

Because Country X lacks a QDMTT, the ultimate Indian parent entity accounts for this 500,000 euro top-up liability under applicable GloBE rules.

Common Pillar Two Compliance Pitfalls

Finance and tax departments navigating Pillar Two frequently encounter four practical challenges:

• Assuming Statutory Rates Prevent Exposure: Relying on a statutory rate above 15% overlooks book-to-tax differences, exemptions, and tax holidays that can push the GloBE ETR below the 15% threshold.
• Fragmented Payroll and Headcount Records: Calculating the payroll carve-out under SBIE requires verifiable employee compensation figures per tax jurisdiction. Groups operating across countries streamline these data inputs through multi-country payroll outsourcing and unified global payroll management.
• Mismatched Accounting Standards: Preparing local accounts under domestic GAAP rather than parent consolidation standards (such as Ind AS or IFRS) leads to discrepancies in GloBE Income calculations. Maintaining synchronized ledgers requires robust record to report outsourcing workflows.
• Ignoring Foreign UTPR Rules: Assuming that delays in domestic Indian legislation eliminate Pillar Two liability is incorrect. Overseas subsidiaries can face top-up assessments through foreign UTPR provisions if undertaxed entities exist elsewhere in the corporate structure.

Frequently Asked Questions

Does Pillar Two apply to standalone mid-sized Indian companies?

No. Pillar Two applies exclusively to multinational enterprise groups with annual consolidated revenues of at least 750 million euros in at least two of the four preceding fiscal years. Standalone domestic companies operating only within India remain outside the scope of GloBE rules.

What is the difference between an IIR and a QDMTT?

A Qualified Domestic Minimum Top-up Tax (QDMTT) permits the source country where low-tax profits arise to collect top-up tax domestically. The Income Inclusion Rule (IIR) allows the parent company's tax authority to collect top-up tax on undertaxed foreign subsidiaries. The QDMTT takes legal precedence over the IIR.

How does the Substance-based Income Exclusion reduce top-up tax?

The Substance-based Income Exclusion (SBIE) deducts a percentage of eligible payroll costs and tangible asset values from GloBE Income. Top-up tax applies solely to the remaining excess profit, protecting tangible business operations from punitive top-up charges.

Are deferred taxes recognised for Pillar Two liabilities under Ind AS 12?

No. Amendments to Ind AS 12 by the MCA introduce a mandatory temporary exception prohibiting companies from recognising deferred tax assets or liabilities linked to Pillar Two. Groups must instead provide qualitative and quantitative footnote disclosures in their financial reports.
