How Multilateral Instruments Are Reshaping Tax Avoidance in Australia

As part of a global effort to curb tax avoidance and ensure transparency in cross-border taxation, Australia has embraced the OECD’s Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (BEPS) — commonly known as the Multilateral Instrument (MLI).

This development has significant implications for multinational enterprises operating in or through Australia.

Enhanced Global Coordination to Track Tax Avoidance

In this post, we outline how the MLI functions, its impact on Australia’s treaty network, and the key considerations for taxpayers navigating this evolving regulatory environment.

A New Era in International Tax Coordination

The MLI, developed by the OECD and G20, enables jurisdictions to rapidly update bilateral tax treaties with minimum renegotiation. Rather than revising treaties individually, the MLI allows participating countries to incorporate standardized anti-avoidance measures into their existing agreements, promoting a consistent international tax framework.

Australia signed the MLI in June 2017, ratified it in 2018, and began applying its provisions progressively from 1 January 2019, depending on the ratification timeline of treaty partners.

Key MLI Measures Implemented in Australia

1. Prevention of Treaty Abuse

A cornerstone of the MLI is the Principal Purpose Test (PPT). This rule denies treaty benefits—such as reduced withholding tax rates—if it is reasonable to conclude that one of the principal purposes of a transaction or arrangement was to obtain that benefit.

For Australian tax treaties, the PPT has been adopted as a minimum standard. This provision strengthens the ATO’s ability to challenge treaty-based structures that lack economic substance or commercial purpose.

2. Enhanced Dispute Resolution Mechanisms

The MLI reinforces the Mutual Agreement Procedure (MAP) to provide more efficient and effective resolution of cross-border tax disputes. Australia has also opted in to mandatory binding arbitration, offering greater certainty for businesses navigating complex treaty matters.

3. Tackling Hybrid Mismatch Arrangements

Hybrid mismatches, where entities or instruments are treated inconsistently between jurisdictions, have been a focus of BEPS Action 2. Through the MLI, Australia has adopted provisions to limit the benefits of such mismatches, ensuring that income is not unduly exempted or deducted twice.

4. Strengthened Permanent Establishment (PE) Provisions

The MLI broadens the definition of permanent establishment to counter the artificial avoidance of taxable presence. This includes:

• Tightening rules around commissionaire arrangements

• Preventing the fragmentation of activities to avoid PE status

• Expanding coverage of dependent agent relationships

These updates increase the likelihood that foreign enterprises conducting business in Australia may now be deemed to have a taxable presence under amended treaty rules.

5. Updated Methods for Eliminating Double Taxation

The MLI provides flexibility in how jurisdictions relieve double taxation, aligning with BEPS Action 6. Australia generally continues to apply the exemption or credit method, depending on the relevant treaty.

Scope of Impact: Treaties Affected

Australia maintains 44 bilateral tax treaties, of which over 35 are currently covered by the MLI. However, not all provisions apply uniformly—each MLI article is subject to specific reservations and notifications by both treaty partners. As such, businesses must carefully assess the applicability of MLI changes on a treaty-by-treaty basis.

Strategic Implications for Multinational Enterprises

The implementation of the MLI significantly alters the cross-border tax landscape. Key takeaways for businesses include:

• Substance over form is paramount. Transactions lacking genuine economic purpose may be denied treaty benefits under the PPT.

• Increased scrutiny of permanent establishment exposure, especially for digital and service-based business models.

• Enhanced MAP and arbitration provisions offer greater legal recourse, but also require careful documentation and audit readiness.

• Hybrid arrangements require reevaluation to avoid denial of deductions or unexpected taxation.

Conclusion

The Multilateral Instrument represents a pivotal shift in how tax treaties are interpreted and enforced, and Australia is at the forefront of this global movement. While the MLI enhances the integrity of the international tax system, it also introduces complexity that businesses must navigate with care.
