Taxation (Multinational—Global and Domestic Minimum Tax) Rules 2024
Summary
The Australian Treasury has issued legislative rules implementing the OECD Pillar Two Global Minimum Tax framework, establishing Income Inclusion Rule (IIR) and Domestic Top-up Tax mechanisms. The rules apply to multinational enterprise groups with consolidated revenue of at least €750 million and impose top-up tax liabilities where foreign jurisdictions apply an effective tax rate below 15% on a jurisdictional basis.
What changed
This legislative instrument establishes the detailed rules for Australia's implementation of the OECD Pillar Two Global Minimum Tax framework, comprising the Income Inclusion Rule (IIR) and Domestic Top-up Tax (DTT). The rules define key concepts including the IIR Top-up Tax Amount, Allocable Share, Inclusion Ratio, and the IIR offset mechanism to prevent double-counting. Part 2-4 establishes the Domestic Top-up Tax Amount to ensure low-taxed Australian income is subject to top-up rather than being collected by other jurisdictions under IIR.
Large multinational enterprises operating in Australia must assess whether they meet the €750 million consolidated revenue threshold. Groups subject to these rules must calculate jurisdictional effective tax rates and determine any top-up tax liability. The instrument operates in conjunction with the Taxation (Multinational—Global and Domestic Minimum Tax) Act 2024 and requires careful attention to allocation mechanics and currency conversion provisions for foreign operations.
What to do next
- Determine if the multinational group meets the €750 million consolidated revenue threshold
- Assess jurisdictional effective tax rates across all operating jurisdictions
- Calculate any IIR Top-up Tax or Domestic Top-up Tax liability
