Australia’s Public Country-by-Country Reporting regime marks an important shift in tax transparency. For many multinational groups, Country-by-Country Reporting is already part of the annual transfer pricing compliance cycle. However, the Australian public CbCR regime should not be treated as a simple re-use of the existing confidential OECD CbCR report.
The Australian rules create a separate public reporting obligation. The information is provided to the Australian Taxation Office in an approved electronic form and is then facilitated for publication on an Australian Government website. The ATO expects the first public release of information in late 2026.
For multinational tax teams, the challenge is therefore not only whether the group is in scope, but whether the data can be collected, validated, reconciled and explained in a way that is suitable for public disclosure.
When does Australian Public CbCR apply?
The regime applies for reporting periods starting on or after 1 July 2024. Reports are due within 12 months after the end of the relevant reporting period. For a group with a 30 June year-end, the first reporting period started on 1 July 2024 and the first report is due by 30 June 2026.
The obligation generally sits with the Public CbC reporting parent, not the Australian subsidiary. This is important for foreign-parented groups. An Australian subsidiary will usually not have its own separate obligation, unless it is not included in the foreign parent’s consolidated accounts and qualifies as a Public CbC reporting parent in its own right.
Broadly, an entity may be in scope where it is a CbC reporting parent with annual global income of at least A$1 billion, has the required connection with Australia, and has at least A$10 million of Australian-sourced aggregated turnover for the reporting period.
Public CbCR is not the same as ordinary CbCR
One of the biggest caveats is that public CbCR and ordinary CbCR are separate measures. Existing OECD CbCR data may be a useful starting point, but it is not sufficient on its own. The ATO explicitly warns that Public CbCR and CbCR are different regimes with different reporting requirements.
This matters because ordinary CbCR was designed for confidential exchange between tax authorities. Australian Public CbCR is designed for public disclosure. That changes the risk profile. The audience is no longer only the tax authority. Investors, journalists, NGOs, competitors, employees and the wider public may read the published information.
As a result, the filing process should include a stronger review of consistency, explanations and reputational sensitivity.
Caveat 1: jurisdiction-by-jurisdiction versus aggregated reporting
The Australian regime does not treat all jurisdictions in the same way.
For Australia and specified jurisdictions, information must be reported on a country-by-country basis. For other jurisdictions, the reporting parent may choose to report either on a country-by-country basis or on an aggregated basis.
This creates an important filing decision. Full country-by-country disclosure may be more transparent and easier to reconcile internally, but it also increases public visibility. Aggregated reporting for other jurisdictions may reduce granularity, but the aggregation must still be complete and technically correct.
A tax team should therefore not only ask: “Can we complete the form?” It should also ask: “What reporting approach are we applying, and can we defend that approach consistently year after year?”
Caveat 2: the specified jurisdiction list is not optional
The specified jurisdictions are determined by legislative instrument. The ATO guidance lists jurisdictions including Singapore, Switzerland, Hong Kong, Bermuda, Cayman Islands, Jersey, Guernsey, Mauritius and several others. These jurisdictions require particular information to be published on a country-by-country basis.
This is a practical data issue. A group may have historically aggregated or reviewed some of these jurisdictions at a regional level for internal reporting purposes. Under the Australian Public CbCR regime, that may not be sufficient.
The filing process should therefore include a jurisdiction-mapping exercise. Each legal entity, permanent establishment and relevant activity should be mapped to the correct tax jurisdiction, and the group should identify whether that jurisdiction is Australia, a specified jurisdiction, or another jurisdiction.
Caveat 3: the required information goes beyond a simple financial table
For Australia and specified jurisdictions, the reporting parent must disclose information including:
- main business activities;
- number of employees on a full-time equivalent basis;
- unrelated party revenue;
- related party revenue from parties that are not tax residents of that jurisdiction;
- profit or loss before income tax;
- tangible assets excluding cash and cash equivalents;
- income tax paid on a cash basis;
- income tax accrued for the current year;
- reasons for differences between tax accrued and the amount that would be due if the jurisdiction’s tax rate were applied to profit or loss before tax; and
- the currency used.
This is where many practical issues arise. Employee data may sit in HR systems, revenue data may sit in ERP systems, tangible asset data may sit in fixed asset registers, and tax paid may be tracked separately from tax accrued. The form may look like a tax filing, but the underlying data comes from multiple systems and teams.
Caveat 4: explanations may be as important as the numbers
The requirement to explain differences between income tax accrued and a notional tax amount based on profit before tax is particularly sensitive.
A low effective tax rate may have perfectly valid reasons, such as losses, timing differences, tax incentives, withholding taxes, prior-year adjustments, non-taxable income or permanent differences. However, once the information is public, unexplained differences may be misunderstood.
The tax team should therefore prepare explanations that are technically correct, concise and understandable to a public audience. The explanation should not read like internal tax jargon. It should help a reader understand why the tax outcome differs from a simple headline-rate calculation.
Caveat 5: the information should reconcile with audited consolidated financial statements
The ATO’s finalised filing guidance and updated public CbCR materials refer to information adopted from GRI 207: Tax 2019 and indicate that the information must reconcile with the reporting entity’s audited consolidated financial statements for the relevant accounting period.
This is a major control point. If the public CbCR figures do not reconcile with the financial statements, ordinary CbCR, local files, master file, tax returns or Pillar Two data, the group may create unnecessary audit and reputational questions.
A robust filing process should therefore include reconciliation checks against:
- consolidated financial statements;
- existing OECD CbCR data;
- local file financial data;
- tax return data;
- permanent establishment data;
- ERP trial balances;
- Pillar Two data, where relevant; and
- prior-year reporting positions.
Caveat 6: XML format and technical validation matter
The approved form is in XML schema format. The ATO has also published a Public CbCR 2025 specification package, including a Business Implementation Guide, schema, XML message structure table and XML example files. The current specification is version 2.0, published in February 2026.
This means the process is not only a tax technical exercise. It is also a data and software exercise. The XML must be generated in the correct structure, with the correct fields, formats and validation rules.
Common technical caveats include:
- incorrect jurisdiction codes or jurisdiction names;
- missing mandatory fields;
- inconsistent currency fields;
- incorrect number formats;
- incomplete entity lists;
- schema validation errors;
- character encoding issues;
- rounding inconsistencies;
- mismatches between aggregated and country-level totals; and
- failure to retain a clear audit trail of the submitted version.
For large groups, manually preparing an XML file can create risk. The better approach is to generate the filing from structured data and validate it before submission.
Caveat 7: registration and authorisation should not be left until the deadline
The ATO encourages Public CbCR reporting parents to register at least four weeks before they intend to engage with the ATO on a public CbCR matter. Registration also allows the reporting parent to authorise representatives, including employees, advisers or nominated persons, to act on its behalf.
This is particularly relevant for foreign-parented groups. The parent entity may be outside Australia, while the practical data collection may be coordinated by the Australian tax team or an external adviser. Without clear authorisation, the filing process may slow down close to the deadline.
Caveat 8: errors may need to be corrected quickly
If a material error is identified, the reporting parent must provide corrected information to the ATO within 28 days after becoming aware of the error. The corrected report must be provided in its entirety.
This creates a strong need for version control. A multinational group should be able to answer:
- Which version was submitted?
- Who approved it?
- Which data sources were used?
- Which validations were performed?
- Which assumptions were applied?
- What changed between versions?
Without a proper audit trail, correcting a public filing can become time-consuming and risky.
Caveat 9: exemptions are possible, but they require evidence
The Commissioner may grant a full or partial exemption for a single reporting period. However, the ATO’s draft practice statement makes clear that the onus is on the entity to justify the exemption and support the request with relevant documents, legal references and analysis of adverse impacts.
Commercial sensitivity alone will not automatically be enough. The ATO indicates that hypothetical or remote detriment will weigh against an exemption, while real, measurable and commercially significant detriment is more relevant. The fact that information is private or not otherwise publicly reported is also unlikely to be sufficient by itself.
Groups considering an exemption should therefore start early and document the specific information, jurisdiction and harm involved.
Caveat 10: public disclosure changes the governance standard
Because the report will become public, the internal review process should be closer to an external reporting process than to a routine tax compliance task.
Relevant stakeholders may include:
- group tax;
- local tax teams;
- finance;
- legal;
- investor relations;
- sustainability or ESG reporting;
- communications;
- transfer pricing;
- IT/data teams; and
- external advisers.
The public CbCR report should be reviewed not only for technical accuracy, but also for consistency with the group’s public tax strategy, sustainability reporting, financial statements and transfer pricing documentation.
How TP Forms helps mitigate the risks and caveats
Australian Public CbCR is not just another compliance form. It requires structured data, jurisdiction mapping, reconciliation, technical XML generation, review controls and clear evidence of the positions taken. This is exactly where TP Forms, TPGenie’s dedicated forms module, can support multinational tax teams.
TP Forms helps generate country-specific transfer pricing forms directly from the data already available in TPGenie. For Australian Public CbCR, this means that relevant entity data, jurisdiction data, financial information, CbCR data and transfer pricing data can be reused in one controlled workflow.
Instead of manually preparing the Australian Public CbCR filing in spreadsheets or trying to build the XML file separately, TP Forms can generate the required XML output based on structured data. This reduces the risk of technical filing errors, missing fields, inconsistent jurisdiction mapping, incorrect formatting and mismatches between the filing and the underlying transfer pricing documentation.
The module also helps mitigate several of the key caveats discussed above:
- Jurisdiction mapping: TP Forms can help distinguish between Australia, specified jurisdictions and other jurisdictions.
- Data consistency: figures can be linked back to existing TPGenie data, reducing inconsistencies between Public CbCR, ordinary CbCR, Local Files and other reporting outputs.
- Completeness checks: required fields and filing logic can be checked before the XML is generated.
- XML generation: the filing can be produced in the required technical format, reducing reliance on manual XML preparation.
- Review and approval: tax teams can review the data before finalisation.
- Audit trail: versions, changes and supporting information can be retained in TPGenie.
- Risk mitigation: the process becomes more controlled, repeatable and defensible.
This matters because Australian Public CbCR is a public disclosure. Errors are not only technical issues; they may also create reputational, audit and governance risks. By using TP Forms, multinational groups can move away from manual form preparation and towards a structured, validated and traceable filing process.
In short, TP Forms helps tax teams generate the Australian Public CbCR XML, reduce manual work and mitigate the practical risks that come with public tax reporting.
Conclusion
Australian Public CbCR should not be treated as a last-minute form-filling exercise. The regime combines tax technical analysis, public disclosure, XML filing, data reconciliation and governance.
The main challenge is not only producing the numbers. The real challenge is producing numbers that are complete, explainable, reconcilable and ready for public scrutiny.
For multinational tax teams, the practical message is clear: start with the data, define the reporting approach, validate the XML, document the assumptions and make sure the final report is consistent with the wider transfer pricing and tax reporting position of the group.
