1. Prepare for Global Minimum Tax (Pillar Two) Compliance
The global tax landscape has changed. Australia has officially implemented the OECD Pillar Two global minimum tax rules. If your business is part of a large multinational group with consolidated annual revenue of EUR 750 million or more, you are now subject to a 15% global minimum tax.
This isn’t just a theoretical change; it is an active compliance requirement. You must now prepare to file new Australian Income Inclusion Rule/Undertaxed Profits Rule (AIUTR) and Domestic Minimum Tax (DMT) returns. The ATO expects to streamline this into a single return, often referred to as the CGDMTR.
Why this matters for you:
The first filings are due on 30 June 2026. While that might seem a few months away, the data collection required for these returns is immense. Failing to plan for this can lead to significant cash flow disruptions and heavy penalties.
2. Navigate the New Public Country-by-Country Reporting
Transparency is no longer optional in Australia. The new public Country-by-Country Reporting (CbCR) regime is now in full swing. For the first time, large multinationals are required to disclose jurisdiction-level tax and financial data to the public.
Previously, this data was shared privately with tax authorities. Now, it will be available for public scrutiny. This shift means you need to consider more than just the numbers; you must consider your brand’s reputation.
Action steps for sellers:
- Audit your data: Ensure your jurisdiction-level reporting is accurate before it becomes public.
- Coordinate with your compliance team: Ensure your data is structured correctly to meet these transparency standards.
- Watch the clock: First reports are also due in June 2026.
3. Review Your Cross-Border Financing and Interest Deductions
Are you using related-party debt to finance your Australian operations? If so, you need to act quickly. Effective from July 2024, Australia’s Debt Deduction Creation Rules (DDCR) permanently deny interest deductions for certain related-party debt arrangements.
There is no transitional relief for these rules. This means if your current financing structure falls under these rules, you are losing money on every interest payment that is no longer deductible.
The Benefit of Reviewing Now:
Reviewing your cross-border financing arrangements today will help you prepare for your 2025 and 2026 disclosure obligations.
4. Master the Stricter Foreign Income Tax Offset (FITO) Rules
If you are paying tax in multiple jurisdictions, you likely rely on the Foreign Income Tax Offset (FITO) to avoid double taxation. However, the ATO has tightened the requirements for claiming these offsets.
To successfully claim a FITO, the foreign tax must be:
- Validly imposed under the laws of the foreign country.
- Directly related to income that is also included in your Australian assessable income.
Crucially, you cannot claim an offset for taxes that are refundable or linked to other benefits provided by the foreign government. Additionally, you must “gross up” your foreign income in your Australian tax returns.
5. Keep Track of New Filing Deadlines and Exemptions
The ATO has introduced a variety of new return types and deadlines that vary depending on your business structure. While the June 2026 deadline for Pillar Two is the most prominent, there are other nuances to keep in mind.
Lodgment Exemptions:
There is some good news. The ATO has introduced lodgment exemptions for certain MNE entities that can only ever have nil tax liabilities. However, do not assume you are exempt automatically. In many cases, you may still be required to file a “nil return” to remain compliant.
General Deadlines:
- Initial Year: Generally 18 months after the first applicable income year.
- Subsequent Years: 15 months for later years.
