OECD PILLAR TWO 15% Global Minimum Tax
OECD PILLAR TWO 15% Global Minimum Tax 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: De Minimis Test: Revenue < €10M and income < €1M in CbCR Simplified ETR Test: ETR computed using CbCR data ≥ transitional rates (15% for 2024, 16% for 2025, 17% for 2026) Routine Profits Test: GloBE income ≤ SBIE computed from CbCR data 4.
