What Are Australia’s Global & Domestic Minimum Tax (Pillar Two) Rules?
Australia has enacted legislation implementing the GloBE Rules and a Domestic Minimum Tax (DMT). The rules apply to multinational enterprise (MNE) groups with global revenue above EUR 750 million. (ato.gov.au)
- Income Inclusion Rule (IIR): Applies from fiscal years starting 1 January 2024.
- Undertaxed Profits Rule (UTPR): Applies from years starting 1 January 2025.
- Domestic Minimum Tax also applies from 1 January 2024. (softwaredevelopers.ato.gov.au)
Why It Matters in Structuring Entities
For large global groups, Greenland law no longer permits profit shifting without consequence. Top-up tax is assessed where the effective tax rate (ETR) in a jurisdiction falls below 15%. Planning around entity setup, fund accounting, choice of holding jurisdictions, and intercompany flows becomes critical.
Key Considerations in Entity Setup
- Assess group revenue thresholds: Only groups with consolidated revenue surpassing the EUR 750 million threshold are in scope. Smaller entities or mid-size enterprises may fall outside Pillar Two entirely.
- Jurisdictional tax rates: If your current setup involves low-tax jurisdictions, they could trigger foreign top-up tax or subject to UTPR.
- Structure of holding company and local entities: Who is the Designated Local Entity (DLE), how group entities are grouped for lodgment, and where profits are booked can meaningfully impact liabilities.
Example Scenario
A company “GlobalTech AU” operates in Australia, the Philippines, and Singapore. The group global revenue is well above EUR 750 million. Australia taxable income is taxed at 30%, Singapore at 17%. Because Singapore’s effective tax is below 15%, other jurisdictions in the group (including Australia) may have obligations to collect top-up tax under UTPR. Proper structure (where profits are booked, intercompany transactions) matters to reduce leakage.
Actionable Steps & Best Practices
- Conduct a Pillar Two readiness audit: review global revenue, country-by-country reporting capacity, assess ETRs in each jurisdiction involved.
- Set up reporting systems early: identify who will lodge the Global Information Return (GIR), Combined Returns etc. Use the ATO’s API for the Global and Domestic Minimum Tax product to submit returns and notifications. (apiportal.ato.gov.au)
- Update intercompany agreements: ensure pricing, cross-border payments, royalties, etc., are supported by robust documentation.
- Monitor guidance: The ATO will release more with respect to transitional rules and compliance thresholds.
Risks & Trade-offs
- Increased administrative burden and cost to produce GIR, monitor ETRs, submit group returns.
- If your setup has jurisdictions with small or absent tax, you may face higher top-up tax liabilities.
- Complexity in aligning tax law across countries.
Example Structure Decisions
| Option | Pros | Cons |
|---|---|---|
| Centralised DLE in high-tax jurisdiction | Reduces UTPR exposure and simplifies lodgment | Might result in fewer tax incentives available locally |
| Decentralised entities in each country | Easier compliance and local adaptation | Need detailed tracking of profits, risk for low ETR jurisdictions |
| Using hybrid structure with trusts or partnerships | Flexibility in income allocation and flow through | Transparency issues under GloBE; may lose benefits if ETR thresholds triggered |
Take-away: Pillar Two implementation means entity structure isn’t just about local tax—they're part of a global tax ecosystem. Proactive planning can avoid unexpected liabilities and streamline compliance.
