Pillar Two: The 15% Global Minimum Tax at a Glance

Definition

Pillar Two is the BEPS 2.0 project’s global minimum top-up tax — the OECD/G20 Inclusive Framework’s design for a 15% minimum effective tax rate on the profits of large multinational groups, the second of the BEPS project’s two pillars (Pillar One being the allocation reform — the taxing rights over the residual profits of the most profitable MNEs — the Pillar Two the floor reform). The mechanics in one breath: an MNE group with consolidated revenue of €750 million or more (the scope test, the base year) is in scope; for each jurisdiction, the group’s jurisdictional effective tax rate (ETR) is computed (the tax paid/accrued over the covered profit — the GloBE rules the computation, the [SBIE] (/docs/glossary/sbie) the substance-based exclusion of the payroll and PP&E returns); where the jurisdictional ETR is below 15%, the difference is the undertaxed profit, and the top-up tax — the charge that brings the jurisdiction’s effective rate up to 15% — is levied by one of three mechanisms: the IIR (the income inclusion rule — the parent’s jurisdiction charges the parent), the UTPR (the undertaxed profits rule — the backstop where the IIR does not reach), and the QDMTT (the qualified domestic minimum top-up tax — the low-tax jurisdiction’s own charge, where enacted, taking priority). The [pillar two guide] (/docs/pillar-two/pillar-two-guide) carries the full treatment — the why, the scope, the mechanics at a glance, the [India status] (/docs/pillar-two/pillar-two-guide) (India’s position as of this writing), and the [IIR/UTPR/QDMTT guide] (/docs/pillar-two/iir-utpr-qdmtt) the charging map. The interaction with transfer pricing is the standing one: the same group data (the CbCR — the country-by-country reporting — the Pillar Two data backbone, the shared €750 mn scope) feeds both, and the TP adjustments and the FAR-based characterizations that shape the profits are the inputs the GloBE computation reads — the [pillar two for tp teams guide] (/docs/pillar-two/pillar-two-for-tp-teams) the workflow and data checklist.

Pillar Two, in one computation:
  1. The scope (the MNE group — consolidated revenue ≥ €750 mn — the base-year test)
  2. The ETR (per jurisdiction — the tax over the covered profit — the GloBE computation, the SBIE excluded)
  3. The undertaxed profit (the ETR < 15% — the difference to the 15% floor)
  4. The top-up (the charge to the 15% — the IIR (the parent), the UTPR (the backstop), the QDMTT (the domestic, where enacted))

The element	The content
The floor	The 15% minimum effective tax rate — the jurisdictional ETR below 15% triggers the top-up (the difference to 15%, the undertaxed profit)
The scope	The MNE group with consolidated revenue ≥ €750 million (the base-year test, the two-year grace where crossed) — the same threshold family as the CbCR and the Master File
The computation	The GloBE rules — the jurisdictional ETR, the covered taxes, the SBIE (the substance-based income exclusion — the payroll + PP&E returns excluded)
The mechanisms	The IIR (primary — the parent’s charge), the UTPR (secondary — the backstop), the QDMTT (domestic — where enacted, the priority) — the IIR/UTPR/QDMTT guide

The working read (the pillar two guide): Pillar Two is not a new tax on the profits — it is a top-up on the difference between the jurisdiction’s effective rate and the 15% floor (the undertaxed profit the charge’s base, the top-up tax the charge’s form), and it is a group-level computation (the consolidated CbC entity, the jurisdictional ETRs, the allocation of the top-up among the in-scope jurisdictions) — the GloBE rules the computation’s mechanics, the [ETR and SBIE guide] (/docs/pillar-two/etr-sbie) the exclusions that matter (the [SBIE] (/docs/glossary/sbie) — the payroll and PP&E returns excluded from the covered profit, the [transitional safe harbour] (/docs/glossary/transitional-safe-harbour) the 3-year CbCR-based fast path that can avoid the top-up for the applicable years). The India angle: the pillar two guide carries India’s position (the enactment status, the group-level implications for the Indian entities of the in-scope groups) — and the [CbCR and Pillar Two] (/docs/pillar-two/cbcr-and-pillar-two) guide the data backbone (the CbCR data the GloBE computation’s input, the data-quality requirements the shared discipline). The [pillar two for tp teams] (/docs/pillar-two/pillar-two-for-tp-teams) guide is the workflow layer — the new data duties, the system impacts, the interaction with the TP documents (the same profits, the two computations, the reconciliation), the action checklist.

Example

An MNE group: consolidated revenue €2.1 bn (in scope — the €750 mn test), the ultimate parent in a 25%-rate jurisdiction, with operations in Jurisdiction A (the IP holding, the 5% effective rate — the sub-15% jurisdiction), Jurisdiction B (the manufacturing, the 20% ETR), and India (the operations, the 25%+ ETR). The Pillar Two computation (the GloBE rules):

The jurisdiction	The ETR	The position	The top-up
Jurisdiction A (the IP holding)	5%	Sub-15% — the undertaxed profit	The top-up on the difference (the 5% → 15% — the IIR the parent’s charge, where A has no QDMTT; the UTPR the backstop, the allocation to the in-scope jurisdictions)
Jurisdiction B (the manufacturing)	20%	Above 15%	No top-up (the ETR above the floor)
India (the operations)	25%+	Above 15%	No top-up (the ETR above the floor)

The group’s Pillar Two exposure is the Jurisdiction A top-up (the IP holding’s sub-15% ETR — the classic exposure, the [pillar two guide] (/docs/pillar-two/pillar-two-guide)’s standing fact pattern) — the [IIR] (/docs/glossary/iir) charging the parent (the parent’s jurisdiction, the 25% rate, the top-up the charge on the undertaxed profit), the [QDMTT] (/docs/glossary/qdmtt) (where A enacts it) taking priority (the domestic charge first, the IIR the fallback). The TP interaction: the IP holding’s 5% ETR is the TP outcome (the royalty/fee the IP’s exploitation priced, the DEMPE the IP’s value creation allocated) — the Pillar Two top-up is the tax on that outcome, and the [pillar two for tp teams] (/docs/pillar-two/pillar-two-for-tp-teams) checklist (the data, the reconciliation, the system impacts) is the TP team’s work.

FAQ

What is Pillar Two, in one sentence? The OECD/G20 global minimum top-up tax: a 15% floor on the effective tax rate of large MNE groups (consolidated revenue ≥ €750 mn), computed per jurisdiction (the GloBE rules, the ETR over the covered profit, the SBIE excluded), with the difference to 15% (the undertaxed profit) charged as the [top-up tax] (/docs/glossary/top-up-tax) by the IIR (the parent), the UTPR (the backstop), or the [QDMTT] (/docs/glossary/qdmtt) (the domestic, where enacted) — the pillar two guide the full treatment.

How is Pillar Two different from Pillar One? The reform: Pillar One is the allocation reform — the taxing rights over the residual profits of the most profitable MNEs (the profits allocated to the market jurisdictions, the user countries’ share, the Amount A / Amount B of the Pillar One design); Pillar Two is the floor reform — the 15% minimum effective rate on the groups’ profits (the top-up on the sub-15% jurisdictions, the GloBE computation). One allocates taxing rights (Pillar One, the residual profits to the markets); the other floors the effective rate (Pillar Two, the top-up to 15%). The Pillar Two is the one with the immediate compliance burden (the GloBE computation, the top-up, the enactment map) — the [pillar two guide] (/docs/pillar-two/pillar-two-guide) carries both pillars’ context, the Pillar Two the focus.

What is India’s position on Pillar Two? The [pillar two guide] (/docs/pillar-two/pillar-two-guide) carries India’s status (the enactment position as of this writing — the government’s stance on the GloBE enactment, the domestic legislation’s status). The practical implication for the Indian entities of the in-scope groups: the [CbCR] (/docs/glossary/cbcr) data (the Indian rows, the [Form 3CEBA] (/docs/glossary/form-3ceba) where the group’s CbCR is prepared abroad) is the Pillar Two data backbone (the CbCR and Pillar Two guide), and the Indian operations’ ETR (the 25%+ — above the floor) means the Indian entities are not the sub-15% jurisdictions (the top-up is the other jurisdictions’ — the IP holdings, the low-tax entities — the IIR / QDMTT the charge). The [pillar two for tp teams] (/docs/pillar-two/pillar-two-for-tp-teams) checklist is the data duty (the Indian rows, the reconciliation, the system impacts) — the TP team’s work, the India angle the guide’s section.
