What is OECD
Pillar Two?
OECD Pillar Two is the global minimum-tax framework establishing a 15% effective tax rate (ETR) for multinational groups with consolidated revenue at or above EUR 750 million. The framework operates through three mechanisms: the Income Inclusion Rule (IIR), the Undertaxed Profits Rule (UTPR), and the Qualified Domestic Minimum Top-up Tax (QDMTT). The UAE has implemented QDMTT to retain top-up tax revenue domestically rather than ceding it to foreign jurisdictions.
What are the three Pillar Two mechanisms?
- Income Inclusion Rule (IIR) — the parent jurisdiction imposes top-up tax on under-taxed income earned by foreign subsidiaries.
- Undertaxed Profits Rule (UTPR) — backstop mechanism. Where IIR does not capture the under-taxed income, UTPR allocates the top-up tax to other group jurisdictions.
- Qualified Domestic Minimum Top-up Tax (QDMTT) — the source jurisdiction collects the top-up tax itself, before IIR or UTPR engages.
Who is in scope?
Multinational groups with consolidated revenue at or above EUR 750 million in at least 2 of the 4 prior financial years. The threshold applies at ultimate parent entity (UPE) level. Government entities, certain investment funds, pension funds and non-profit entities are excluded; most family-office structures and mid-market businesses fall below the threshold.
How is the 15% ETR calculated?
The Pillar Two ETR is calculated jurisdiction-by-jurisdiction. GloBE income is determined per OECD methodology (broadly: financial-accounting income with adjustments). Covered taxes (corporate income tax, equivalent) are aggregated. The ETR is taxes divided by GloBE income. Where ETR is below 15%, top-up tax brings the rate to 15%.
What is the Substance-Based Income Exclusion (SBIE)?
SBIE excludes a portion of income from the top-up calculation, calculated as a percentage of payroll costs and the carrying value of tangible assets. The percentages decline over a transition period but remain meaningful in the long term. SBIE rewards economic substance — real people, real premises, real activity.
How does Pillar Two affect UAE structures?
For in-scope multinationals operating in the UAE:
- The 0% Free Zone Person rate no longer delivers its intended economic benefit; QDMTT brings the effective rate to 15%.
- Structural focus shifts to substance positioning and SBIE optimisation.
- Intra-group financing positions need redesign.
- IP-asset location requires substance-justified placement.
- Transfer-pricing positions face heightened scrutiny.
Sub-threshold groups remain unaffected by Pillar Two but operate in an environment that has changed permanently.
