Frequently Asked Questions
What is Pillar 2 and the global minimum tax?
Pillar 2 is an OECD framework that imposes a 15% global minimum effective tax rate on multinational groups with consolidated revenue of EUR 750 million or more. If a group’s effective tax rate in any jurisdiction falls below 15%, top-up taxes are applied to bring the rate to the minimum. This ensures large multinationals pay a fair share of tax globally.
When did Pillar 2 take effect in the UK?
The UK implemented Pillar 2 through the Multinational Top-up Tax (MTT), effective for accounting periods beginning on or after 31 December 2023. The UK also introduced a Domestic Top-up Tax (DTT) from the same date to ensure UK profits are taxed at the 15% minimum before other jurisdictions can levy top-up taxes.
What is the GloBE Information Return?
The GloBE Information Return is the standardised filing required under Pillar 2 rules. It contains jurisdiction-by-jurisdiction data on GloBE income, adjusted covered taxes, effective tax rates, and any top-up tax liabilities. UK groups must file this with HMRC within 15 months of the fiscal year-end (18 months for the first year).
What are transitional safe harbours?
Transitional safe harbours allow qualifying multinational groups to avoid detailed GloBE calculations for certain jurisdictions during the initial years of Pillar 2 implementation (2024-2026). If a jurisdiction meets specific tests based on Country-by-Country Report data, the top-up tax for that jurisdiction is deemed zero, significantly reducing compliance burden.
What are the costs for Pillar 2 support?
Pillar 2 compliance costs vary based on the number of jurisdictions, the complexity of your group structure, and the level of support needed. We offer services from initial impact assessments to full GloBE Information Return preparation. Contact us for a free scoping discussion.
