OECD Pillar Two – 15% Global Minimum Tax: Complete Guide 2026

The OECD/G20 Inclusive Framework’s Pillar Two — also known as the Global Anti-Base Erosion (GloBE) Rules — represents the most significant overhaul of international corporate taxation in more than a century. By establishing a global minimum corporate tax rate of 15%, it aims to end the decades-long race to the bottom where multinational enterprises (MNEs) shifted profits to low-tax jurisdictions, depriving nations of critical tax revenues.

As of 2026, over 140 countries have agreed to adopt the framework, and India stands at a pivotal juncture — having integrated Pillar Two principles into its domestic tax regime while also grappling with the implications for its vast pool of international investments, Special Economic Zones (SEZs), and outbound Indian multinationals. This guide covers every aspect of Pillar Two — from global architecture to India-specific impact, calculations in Indian Rupees (₹), and what businesses must do right now.

1. Background — The Race to the Bottom & Why Pillar Two Was Needed

For decades, multinational corporations exploited gaps and mismatches in international tax rules to minimise their global tax burden. Structures such as the ‘Double Irish’, ‘Dutch Sandwich’, and ‘Singapore Hub’ allowed MNEs to route profits through low or zero-tax jurisdictions, often paying effective tax rates (ETRs) of less than 5% or even 0% on billions of dollars of profit.

1.1 The BEPS Project — Setting the Stage

The OECD launched the Base Erosion and Profit Shifting (BEPS) project in 2013, resulting in 15 Action Plans in 2015. While BEPS Actions addressed specific avoidance techniques, they did not eliminate the fundamental incentive for profit shifting — the existence of jurisdictions with very low or zero tax rates.

1.2 The Two-Pillar Solution

In October 2021, the OECD/G20 Inclusive Framework reached a landmark agreement on a Two-Pillar Solution:

• Pillar One: Re-allocation of taxing rights — large MNEs (revenue > €20 billion, profit margin > 10%) must pay a portion of their residual profits to market jurisdictions (where customers are). Effective 2026–27.
• Pillar Two: Global minimum tax of 15% — ensures that MNEs with consolidated global revenue of €750 million or more pay at least 15% tax in every jurisdiction where they operate.

Key Context for India India is both a source country (many foreign MNEs operate here) and a residence country (Indian MNEs like Tata, Infosys, Wipro, Reliance operate globally). Both dimensions are impacted by Pillar Two. India’s standard corporate tax rate is 22% (base) / 15% (new manufacturing companies under Section 115BAB), making the interaction with the 15% minimum tax complex.

2. What is OECD Pillar Two? — Core Architecture

Pillar Two is a comprehensive set of rules designed to ensure that large MNEs pay a minimum effective tax rate of 15% on profits earned in each jurisdiction. It operates through a system of interlocking domestic and treaty-based rules.

2.1 Scope — Who Does It Apply To?

Pillar Two applies to Multinational Enterprise (MNE) Groups with:

• Annual consolidated revenue of €750 million (approximately ₹6,750 crore at ₹90/€) or more in at least 2 of the preceding 4 fiscal years.
• Operations in at least two jurisdictions.

It does NOT apply to:

• Government entities, international organisations, non-profit organisations, and pension funds.
• Investment funds and real estate investment vehicles that are Ultimate Parent Entities (UPEs).
• Pure domestic groups (operating in only one country).

2.2 Key Pillar Two Rules — Overview

Rule	Full Name	Who Applies It	Trigger
IIR	Income Inclusion Rule	Parent jurisdiction	Top-up tax on low-taxed foreign subsidiary profits
UTPR	Undertaxed Profits Rule	Any group jurisdiction	Backstop if IIR not applied; denies deductions or imposes top-up
STTR	Subject to Tax Rule	Source country (treaty)	Withholding tax if intra-group payments taxed below 9%
QDMTT	Qualified Domestic Minimum Top-up Tax	Source jurisdiction itself	Domestic version of top-up tax; keeps revenue in source country

3. The GloBE Rules — Detailed Mechanics

3.1 Effective Tax Rate (ETR) Calculation

The ETR under GloBE is calculated jurisdiction-by-jurisdiction using the following formula:

GloBE ETR Formula GloBE ETR = Adjusted Covered Taxes ÷ GloBE Net Income  If GloBE ETR < 15%  →  Top-up Tax is triggered Top-up Tax = (15% − GloBE ETR) × GloBE Net Income − Substance-Based Income Exclusion (SBIE)

3.2 Adjusted Covered Taxes

Covered Taxes include current and deferred income taxes. Key adjustments include:

• Deferred Tax Assets (DTAs) from losses may be included but are subject to a 15% recapture threshold.
• Taxes related to excluded dividends or equity gains are removed.
• Certain non-income taxes (GST, customs duties) are NOT covered taxes under GloBE.

3.3 GloBE Net Income

GloBE Income starts from financial accounting income (IFRS/Ind AS) with specific adjustments:

• Excluded dividends and equity gains removed
• Policy disallowed expenses (bribes, fines) added back
• Asymmetric foreign currency gains/losses adjusted
• Qualified Refundable Tax Credits treated as income

3.4 Substance-Based Income Exclusion (SBIE)

SBIE is a carve-out for real economic activity — it reduces the base on which top-up tax is computed. It is calculated as:

SBIE Formula SBIE = (5% × Eligible Payroll Costs) + (5% × Eligible Tangible Asset Net Book Value)  Note: During transition period (2026), the payroll percentage is 9.8% and tangible assets rate is 7.8% — these reduce to 5% by 2033.

3.5 De Minimis Exclusion

A jurisdiction is excluded from top-up tax if both conditions are met:

• Average GloBE Revenue in that jurisdiction is less than €10 million (approx. ₹90 crore)
• Average GloBE Net Income is less than €1 million (approx. ₹9 crore)

3.6 Transitional Country-by-Country Report (CbCR) Safe Harbour

For the years 2024–2026 (transition period), an MNE may apply the Transitional CbCR Safe Harbour which exempts a jurisdiction from detailed GloBE calculations if any one of three tests is met:

1. De Minimis Test: Revenue < €10M and income < €1M in CbCR
2. Simplified ETR Test: ETR computed using CbCR data ≥ transitional rates (15% for 2024, 16% for 2025, 17% for 2026)
3. Routine Profits Test: GloBE income ≤ SBIE computed from CbCR data

4. Income Inclusion Rule (IIR) — How It Works

The IIR is the primary charging rule under Pillar Two. It operates like a ‘top-up’ CFC (Controlled Foreign Corporation) rule at the parent level.

4.1 How IIR Is Applied

4. Parent entity (UPE) calculates the GloBE ETR for each jurisdiction of its subsidiaries.
5. If ETR < 15%, the top-up tax is calculated.
6. The top-up tax is collected by the UPE’s home jurisdiction.
7. If the parent is also subject to an IIR, intermediate holding companies can be used (Intermediate Parent Entity — IPE rule).

4.2 IIR Allocation

When multiple tiers of ownership exist, the IIR is allocated top-down — the highest-tier parent that has implemented IIR collects the tax. This prevents double taxation of the same undertaxed profits.

Numerical Example — IIR (in Indian Rupees) Indian MNE Group (HoldCo India) has a subsidiary in Singapore. Singapore subsidiary GloBE Net Income: ₹100 crore Adjusted Covered Taxes paid in Singapore: ₹10 crore GloBE ETR = ₹10Cr ÷ ₹100Cr = 10% Shortfall = 15% − 10% = 5% SBIE (payroll + tangible assets carve-out) = ₹8 crore Top-up Tax Base = ₹100Cr − ₹8Cr = ₹92 crore IIR Top-up Tax payable by India HoldCo = 5% × ₹92Cr = ₹4.6 crore

5. Undertaxed Profits Rule (UTPR) — The Backstop

The UTPR is the secondary charging rule — it acts as a backstop when the IIR has not been applied (e.g., because the parent jurisdiction has not yet enacted GloBE rules).

5.1 How UTPR Works

• It operates by denying deductions or making equivalent adjustments at the level of entities in the group that are located in UTPR-implementing countries.
• UTPR is allocated among UTPR-implementing jurisdictions based on employee headcount and tangible assets.
• UTPR cannot be applied against the UPE’s own jurisdiction (the UPE exclusion).

5.2 UTPR Timeline

• Most EU countries, UK, Japan, South Korea, Australia — UTPR effective 1 January 2025.
• India — UTPR rules under domestic legislation being finalised; expected full implementation by 2026.
• USA — Legislation pending as of 2026; currently opposing UTPR through domestic policy.

6. Subject to Tax Rule (STTR) — Protecting Developing Nations

The STTR is a treaty-based rule that specifically protects developing countries — allowing source countries (including India) to impose a withholding tax of up to 9% on certain intra-group payments (interest, royalties, service fees) where the receiving jurisdiction taxes those payments at below 9%.

6.1 STTR and India

• India, as a developing economy and a significant source of inbound FDI and royalty payments, has a strong interest in the STTR.
• India’s existing withholding tax rates on royalties/FTS (Fees for Technical Services) to non-residents range from 10% to 20% under the Income Tax Act (Section 115A), often reduced by tax treaties to 10-15%.
• STTR allows India to ‘top up’ withholding to 9% minimum where treaty rates are lower AND the recipient country taxes below 9%.
• India has signed the Multilateral Instrument (MLI) and is expected to update bilateral tax treaties to incorporate STTR by 2026.

STTR — What It Means for Foreign Companies in India Foreign companies receiving royalties or technical service fees from India must ensure they are subject to at least 9% tax in their home jurisdiction on such income. If not, India can apply the STTR top-up. This primarily impacts companies in low-tax treaty jurisdictions like Mauritius, Singapore, Netherlands, and UAE that are used as conduit structures.

7. Qualified Domestic Minimum Top-up Tax (QDMTT) — India’s Strategic Choice

A QDMTT allows India (or any jurisdiction) to impose a domestic top-up tax on its own low-taxed MNE subsidiaries, thereby capturing the GloBE top-up tax revenue domestically rather than allowing foreign parent jurisdictions to collect it under the IIR.

7.1 Why QDMTT Is Critical for India

• Without a QDMTT, if a foreign MNE’s Indian subsidiary is undertaxed below 15% GloBE ETR, the parent jurisdiction collects the top-up under IIR — India gets nothing.
• With a QDMTT, India collects the top-up tax domestically — boosting India’s tax revenue.
• QDMTT safe harbour: If India has a QDMTT, foreign parent jurisdictions must credit India’s domestic top-up against their IIR liability, preventing double taxation.

7.2 QDMTT and SEZ/Manufacturing Incentives

This is the most critical intersection for India:

• Companies in SEZs enjoy 0% tax for initial years under the SEZ Act 2005 and Section 10AA of Income Tax Act.
• New manufacturing companies under Section 115BAB get a 15% tax rate — exactly at the GloBE minimum threshold.
• Companies under Section 115BAB with additional deductions (accelerated depreciation, R&D) may have GloBE ETR below 15% even with the 15% statutory rate.
• Companies in SEZs are most at risk — QDMTT or IIR may neutralise the tax holiday benefit entirely.

India QDMTT Status — 2026 The Government of India introduced provisions in the Finance Act 2025 to enable QDMTT-compatible domestic minimum tax legislation. The full QDMTT framework is expected to be effective from Assessment Year 2026-27. India’s QDMTT will apply to MNE groups with consolidated revenue of €750 million (approx. ₹6,750 crore) or more, operating in India.

8. India’s Response to Pillar Two — Legislative & Policy Developments (2026)

8.1 Finance Act 2024 & 2025 — Key Changes

• Introduction of domestic GloBE-compatible rules in the Income Tax Act via new Chapter XII-GB.
• Notification empowering CBDT to issue rules for GloBE ETR computation aligned with OECD Commentary.
• Amendment to Section 115BAB to clarify interaction with QDMTT for eligible manufacturing companies.
• Pillar Two-compatible Country-by-Country Reporting (CbCR) amendments under Section 286.

8.2 India’s Position on STTR

• India formally opted into STTR via the OECD Multilateral Instrument (MLI) amendment notification in 2024.
• India is renegotiating key tax treaties (Singapore, Mauritius, Netherlands, UAE, Cyprus) to incorporate STTR provisions.
• STTR implementation expected to be complete for major treaties by December 2026.

8.3 Impact on India’s Tax Treaty Network

India has over 90 Double Taxation Avoidance Agreements (DTAAs). Key treaties being reviewed under Pillar Two:

Treaty Partner	Current WHT on Royalty/FTS	STTR Impact	Status (2026)
Singapore	10% (treaty)	Top-up if taxed below 9% in Singapore	Renegotiation in progress
Mauritius	15% (treaty)	Minimal — above 9%	Monitoring
Netherlands	10% (treaty)	Top-up possible for conduits	Renegotiation in progress
UAE	0% (treaty)	STTR fully applicable	Amendment signed 2025
USA	15% (treaty)	Minimal impact	No renegotiation needed
UK	15% (treaty)	Minimal impact	No renegotiation needed

9. Impact on Indian Companies — Outbound MNEs

India is home to several large multinational groups — Tata Group, Infosys, Wipro, HCL, Reliance, Mahindra, L&T, and others — with significant overseas operations. These groups are directly impacted by Pillar Two.

9.1 Which Indian Groups Are In Scope?

Any Indian MNE group with global consolidated revenue of ₹6,750 crore (€750 million) or more in 2 of the last 4 years is in scope. This includes:

• IT services companies with large US/Europe operations
• Pharmaceutical companies with global manufacturing and IP structures
• Infrastructure and energy companies with overseas subsidiaries
• BFSI groups with offshore banking/insurance entities

9.2 Key Risks for Indian Outbound MNEs

• Subsidiaries in low-tax jurisdictions (Ireland, Singapore, Netherlands, UAE, Cayman Islands, Mauritius) may trigger IIR top-up.
• IP holding structures in low-tax jurisdictions are particularly at risk — patent box regimes and IP royalty flows will be scrutinised.
• Tax holiday structures in overseas SEZs may now attract top-up taxes.
• Significant compliance burden: GloBE Information Return (GIR) filing, jurisdiction-by-jurisdiction ETR computation.

9.3 Restructuring Opportunities

• Shift IP holding and treasury centres to higher-tax jurisdictions OR jurisdictions with substance-based activity to increase SBIE carve-out.
• Increase genuine payroll and tangible asset presence in low-tax jurisdictions to maximise SBIE.
• Review entity structures to optimise allocation of IIR vs UTPR.
• Evaluate QDMTT impact in key jurisdictions to ensure no double top-up.

10. Impact on Foreign MNEs Operating in India

India is a major destination for foreign direct investment (FDI) — the world’s 5th largest recipient of FDI. Foreign MNEs with Indian subsidiaries must carefully evaluate their GloBE position in India.

10.1 Is India a Low-Tax Jurisdiction Under GloBE?

For most regular corporates in India, the effective tax rate exceeds 15%:

Tax Regime	Statutory Rate	Effective Rate (approx)	GloBE Risk
Normal Domestic Company	30% + surcharge + cess	~25.17%	No risk — well above 15%
New Tax Regime (Sec 115BAA)	22% + surcharge + cess	~25.17%	No risk
New Manufacturing (Sec 115BAB)	15% + surcharge + cess	~17.01%	Low risk — marginal above 15%
SEZ Units (initial years)	0% (tax holiday)	~0–5%	HIGH RISK — GloBE top-up very likely
Companies with large MAT credits	Varies	May drop below 15% GloBE ETR	Moderate to high risk

10.2 SEZ Units — The Biggest Pain Point

India’s Special Economic Zones have attracted billions of dollars in investment based on the promise of 0% income tax for 5 years (full export profits) and 50% for next 5 years. Under Pillar Two:

• SEZ tax holidays do NOT reduce the GloBE top-up — they are simply treated as zero tax in the ETR calculation.
• Foreign parent entities must pay the GloBE top-up under IIR in their home jurisdiction (e.g., EU parent pays top-up to their government).
• Unless India implements a QDMTT for SEZ companies, the revenue benefit of SEZ investment goes to the parent’s jurisdiction.
• India’s QDMTT framework (2026) includes provisions for SEZ entities — India will collect the top-up domestically.

Financial Impact Example — SEZ Foreign MNE (in ₹) US MNE has India SEZ subsidiary. SEZ GloBE Net Income: ₹500 crore India tax paid (tax holiday): ₹0 GloBE ETR in India: 0% Top-up Tax = 15% − 0% = 15% SBIE (payroll + tangible assets): ₹50 crore Top-up Tax Base = ₹500Cr − ₹50Cr = ₹450 crore GloBE Top-up Tax = 15% × ₹450Cr = ₹67.5 crore This would be collected by USA under IIR OR by India under QDMTT (from 2026-27).

11. GloBE Information Return (GIR) — Compliance Requirements

11.1 What is GIR?

The GloBE Information Return (GIR) is a standardised global tax return that MNE groups must file to report their Pillar Two position. It is analogous to CbCR (Country-by-Country Report) but far more detailed.

11.2 GIR Contents

• Entity-by-entity and jurisdiction-by-jurisdiction GloBE ETR computations
• Details of Adjusted Covered Taxes
• GloBE Net Income calculations with all adjustments
• SBIE calculations (payroll and tangible assets)
• Top-up tax amounts for each jurisdiction
• Safe harbour elections and supporting data
• Details of Qualified Domestic Minimum Top-up Tax paid

11.3 GIR Filing Timeline

Jurisdiction	GIR Filing Deadline	First Year
EU Countries (Germany, France, etc.)	15 months after fiscal year end	FY 2024
UK	15 months after fiscal year end	FY 2024
Japan	15 months after fiscal year end	FY 2024
Australia	15 months after fiscal year end	FY 2024
India (expected)	18 months after fiscal year end (transition)	FY 2025-26
Singapore	15 months after fiscal year end	FY 2025

11.4 Local Filing vs. Centralised Filing

The GIR can be filed centrally by the UPE in its jurisdiction, with notification to other jurisdictions. Where no exchange of information agreement exists, local filing may be required in each jurisdiction — a significant compliance burden.

12. Pillar Two and India’s Bilateral Tax Treaties — Key Interactions

12.1 Treaty Override Concerns

Pillar Two rules are designed to override bilateral tax treaty benefits where they result in taxation below 15%. This raises treaty override concerns:

• Existing treaties with tax sparing provisions (e.g., India-Singapore, India-Mauritius) may conflict with QDMTT/IIR obligations.
• OECD has clarified that GloBE top-up taxes are not covered taxes under existing DTAAs, meaning treaty relief does not apply to reduce IIR/UTPR charges.
• India’s QDMTT will NOT be creditable under existing treaty provisions — specific treaty amendments are needed.

12.2 Multilateral Instrument (MLI) and Pillar Two

India ratified the MLI in 2019. The MLI has been amended to include STTR as an optional provision. India has opted in, and bilateral treaty partners are being notified to incorporate STTR clauses.

13. Pillar Two — Global Implementation Status (2026)

Region/Country		IIR Status	UTPR Status	QDMTT Status
EU (27 countries)		Effective Jan 2024	Effective Jan 2025	Most countries implemented
United Kingdom		Effective Jan 2024	Effective Jan 2025	Implemented
Japan		Effective Apr 2024	Effective Apr 2025	Implemented
South Korea		Effective Jan 2024	Effective Jan 2025	Implemented
Australia		Effective Jan 2024	Effective Jan 2025	Implemented
Canada		Effective Jan 2024	Effective 2026	In progress
Switzerland		Effective Jan 2024	Effective 2025	Implemented
Singapore		Effective Jan 2025	Under legislation	Implemented
UAE		Effective Jan 2025	Under legislation	Implemented
India		Draft legislation 2025	Expected 2026	Expected AY 2026-27
USA		NOT enacted	NOT enacted	NOT enacted
China		Under evaluation	Under evaluation	Under evaluation
Brazil		Effective Jan 2025	Under legislation	Implemented
	USA’s Non-Participation — Impact on India The USA’s refusal to enact Pillar Two (as of 2026) means that US parent companies with Indian subsidiaries will NOT apply IIR against India. However, UTPR could be applied by other jurisdictions (e.g., EU/UK) against US groups. Indian subsidiaries of US MNEs must track developments closely as US legislation could change.

14. Pillar Two — Sectoral Impact in India

14.1 Information Technology (IT) and ITeS

India’s IT sector is among the largest globally with export revenues exceeding ₹25 lakh crore annually. Key impacts:

• IT companies with significant IP assets (software, patents) in low-tax jurisdictions face top-up risk.
• SEZ-based IT companies — top-up tax may significantly increase effective tax costs.
• Global Capability Centres (GCCs) in India — generally taxed normally; GloBE ETR likely above 15%.
• Transfer pricing arrangements for IT services must be re-evaluated in the context of SBIE calculations.

14.2 Pharmaceuticals and Manufacturing

• Pharma companies with IP in Ireland, Netherlands, or Singapore face restructuring needs.
• New manufacturing companies under Section 115BAB (15% tax rate) are at the margin — careful ETR monitoring required.
• Production Linked Incentive (PLI) scheme benefits may reduce GloBE ETR below 15% — QDMTT will capture this.

14.3 Financial Services and Banking

• Indian banks and NBFCs with overseas branches face Pillar Two in the host jurisdiction.
• Offshore FDI holding structures in Mauritius/Singapore — significant restructuring expected.
• Gift City (IFSC) units in Gandhinagar enjoy near-zero tax; QDMTT or IIR will apply on MNE groups.

14.4 Infrastructure and Real Estate

• REITs and InvITs are generally excluded from Pillar Two as investment entities.
• PPP infrastructure projects with tax holidays — GloBE top-up may apply to MNE parents.
• Renewable energy projects with accelerated depreciation benefits — ETR calculation must include deferred tax impact.

14.5 Start-ups and Unicorns

Most Indian start-ups and unicorns are NOT in scope of Pillar Two as they have not yet reached the €750 million consolidated revenue threshold. However, as they scale internationally, they must build Pillar Two compliance capability proactively.

15. Pillar Two — Step-by-Step Compliance Roadmap for Indian MNEs

8. Scoping Assessment: Determine if the group meets the €750M revenue threshold (₹6,750 crore). Map all jurisdictions of operation.
9. Data Collection: Gather financial accounting data (Ind AS/IFRS) for all constituent entities. Identify covered taxes, deferred tax assets/liabilities, and tax holiday positions.
10. ETR Calculation: Compute GloBE ETR jurisdiction-by-jurisdiction. Apply SBIE carve-outs for each jurisdiction. Identify any jurisdiction below 15%.
11. Safe Harbour Evaluation: Apply Transitional CbCR Safe Harbour tests (2024-2026) for each jurisdiction. Document which jurisdictions qualify for safe harbour.
12. Top-up Tax Computation: For non-safe-harbour jurisdictions with ETR < 15%, compute top-up tax. Identify IIR vs UTPR vs QDMTT allocation.
13. Structural Review: Evaluate whether entity restructuring, IP migration, or substance enhancement can reduce top-up tax exposure.
14. GIR Filing Preparation: Prepare GloBE Information Return with all required data. Engage Big 4 / specialist tax advisors for GIR preparation.
15. Domestic Tax Provision: Book current and deferred GloBE tax provisions in financial statements (Note: IASB/ICAI has issued mandatory IAS 12 / Ind AS 12 amendments for Pillar Two disclosures).
16. Monitoring and Annual Compliance: Establish an ongoing GloBE monitoring process. Track changes in OECD guidance, domestic legislation, and safe harbour extensions.

16. Accounting and Disclosure — Pillar Two (Ind AS / IFRS Update 2026)

16.1 Mandatory Exception Under Ind AS 12

The International Accounting Standards Board (IASB) issued an amendment to IAS 12 (incorporated in Ind AS 12) granting a temporary mandatory exception from recognising and disclosing deferred tax assets and liabilities arising from Pillar Two. This is because the interaction between Pillar Two top-up taxes and existing deferred tax balances is highly complex and could be misleading.

16.2 Mandatory Disclosures Required (from 2026)

• That the temporary exception has been applied.
• The current tax expense / income relating to Pillar Two top-up taxes.
• Qualitative and quantitative information about Pillar Two exposure for periods when legislation is enacted but not yet effective.

16.3 Impact on Indian Companies’ Financial Statements

• Indian listed companies (NSE/BSE) with MNE operations must include Pillar Two disclosures in their Annual Reports from FY 2025-26.
• Audit committees must be briefed on GloBE exposure and compliance status.
• SEBI LODR regulations may require specific Pillar Two disclosures in corporate governance sections.

17. Frequently Asked Questions (FAQs)

Q1. Does Pillar Two apply to Indian domestic companies with no overseas subsidiaries?

No. Pillar Two (GloBE Rules) applies only to MNE groups with operations in at least two jurisdictions and consolidated revenue of €750 million or more. Pure domestic Indian companies are not in scope.

Q2. Will the 15% minimum tax eliminate India’s SEZ benefits?

Not eliminate, but significantly reduce. The tax holiday benefit itself is unaffected by domestic Indian tax law. However, the MNE parent entity will face a top-up tax under IIR (in its home jurisdiction) or India’s QDMTT, effectively neutralising the financial benefit for large MNE groups.

Q3. What is the difference between Pillar Two and India’s existing MAT (Minimum Alternate Tax)?

India’s MAT (Section 115JB) is a domestic minimum tax at 15% of book profit, applicable to all Indian companies. GloBE is an international minimum tax at 15% of GloBE Net Income (which differs from MAT book profit) for MNE groups. MAT credits may be counted as covered taxes in some cases, but the calculations are distinct.

Q4. How does Pillar Two affect transfer pricing in India?

Pillar Two and Transfer Pricing are separate frameworks, but they interact. A transfer pricing adjustment by Indian tax authorities increases the GloBE income of the Indian entity and the covered taxes of the counterparty — this can change ETR positions in both jurisdictions. Companies must model TP adjustments’ impact on GloBE ETR.

Q5. What is the penalty for non-compliance with GloBE filing in India?

India’s draft QDMTT legislation includes penalties for failure to file GIR, misrepresentation, and non-payment of QDMTT. Specific penalty amounts will be notified by CBDT rules under Chapter XII-GB. International precedent suggests penalties of up to 0.1% of global turnover for systemic non-compliance.

Q6. Does Pillar Two apply to Partnership Firms and LLPs?

Generally, transparent entities (partnerships, LLPs) are treated as flow-through entities under GloBE — their income and taxes are allocated to the owners/members. However, if an LLP is owned by an MNE group in scope, the LLP’s India income and taxes will be included in the group’s GloBE ETR calculation for India.

19. Future Outlook — Pillar Two and India Beyond 2026

The full global implementation of Pillar Two will fundamentally reshape international tax planning, FDI decisions, and India’s competitive positioning as an investment destination. Key developments to watch:

• India’s QDMTT full enactment and CBDT rules for Chapter XII-GB — expected H1 2026.
• STTR incorporation into India’s major bilateral tax treaties — ongoing renegotiations.
• OECD’s ongoing Administrative Guidance (10+ rounds issued since 2022) — frequent updates affecting calculations.
• USA’s potential adoption of a UTPR/IIR-equivalent following future legislative cycles.
• Impact on India’s FDI inflows — potential redirection of investment from SEZs to non-holiday structures.
• Pillar One implementation — re-allocation of taxing rights for the digital economy — interacts with India’s existing Equalisation Levy.
• India’s opportunity to strengthen its tax base through QDMTT and STTR without appearing anti-investment — a delicate but achievable balance.

India’s Strategic Opportunity By implementing a well-designed QDMTT, India can reclaim top-up tax revenue that would otherwise flow to the jurisdictions of foreign parent companies. Estimates suggest India could collect an additional ₹15,000 to ₹25,000 crore annually from QDMTT on SEZ and incentive-driven investments alone — without changing any domestic incentive structure.
