OECD Pillar Two (15% Global Minimum Tax): FAQ
Pillar Two is the 15% global minimum tax for multinational enterprise groups with consolidated annual revenue ≥ €750M. Most TaxAtlas readers — individuals, founder-stage businesses, mid-size companies — are out of scope. For in-scope groups, Pillar Two changes the calculus on where to locate operations.

What is OECD Pillar Two?
Pillar Two (the GloBE — Global Anti-Base Erosion — rules) imposes a 15% effective minimum tax on multinational enterprise (MNE) groups with consolidated annual revenue ≥ €750M. Three rule components implement it: QDMTT (the country tops up its own in-scope entities to 15%), IIR (the parent country tops up foreign subsidiaries below 15%), and UTPR (backstop denying deductions where neither QDMTT nor IIR catches the shortfall).
Does Pillar Two apply to me as an individual or small business?
No. Pillar Two applies only to MNE groups with €750M+ consolidated annual revenue. Individuals, founder-stage businesses, mid-size companies, and most family offices are out of scope. The headline rates on country pages still apply to your situation. Pillar Two changes nothing at the corporate level for sub-€750M businesses.
Which jurisdictions have implemented Pillar Two?
As of June 2026, all major EU members, the UK, Switzerland, Canada, Australia, Singapore, Malaysia, Thailand, Hong Kong (announced), UAE, Bahrain (first GCC country), Cayman, BVI, Bermuda, Gibraltar, and all three Crown Dependencies have legislated some combination of QDMTT/IIR/UTPR. Estonia and Malta elected the EU Article 50 6-year deferral. The US has not enacted GloBE rules; GILTI remains the US-specific minimum-tax mechanism. See the full /pillar-two/ tracker for status by jurisdiction.
What does QDMTT mean in practice?
Qualified Domestic Minimum Top-up Tax — the country imposes a domestic top-up to bring in-scope MNE entities to 15% effective. The key feature: QDMTT revenue stays in the local country rather than being collected by parent jurisdictions under IIR. For traditional zero-tax jurisdictions (UAE, Cayman, BVI, Bermuda, Bahrain), QDMTT was the obvious response — collect the 15% locally rather than ceding it to other countries.
How does Pillar Two interact with CFC rules?
For in-scope MNE groups, where a CFC subsidiary's local jurisdiction imposes a 15% QDMTT, the parent country's IIR typically yields to the QDMTT — the local top-up tax is creditable for the parent's Pillar Two calculation. CFC rules continue to apply alongside Pillar Two but the rate effects often collapse to the 15% floor. For sub-Pillar-Two structures, CFC rules remain the binding parent-country constraint.
Does Pillar Two end the rate advantage of zero-tax jurisdictions?
For in-scope MNE groups: yes, the headline-rate advantage collapses to a 15% effective floor. Substance, treaty network, and operational ergonomics now matter more than headline rate. For sub-Pillar-Two structures (most founder-stage businesses), the original rate advantage is preserved — UAE Free Zone QFZP at 0%, Cayman 0%, BVI 0% all still apply to non-MNE entities.
When does Pillar Two compliance start?
Generally for fiscal years starting on or after 31 December 2023 (IIR) or 31 December 2024 (UTPR) in jurisdictions that transposed the EU Minimum Tax Directive. Some jurisdictions started later — UAE DMTT from 1 January 2025, Bahrain DMTT from 1 January 2025, Cayman/BVI/Bermuda QDMTT from 1 January 2025, Cyprus retroactive to 31 December 2023. First compliance returns typically due 18 months after the first in-scope fiscal year-end.
