Country-by-country reporting (CbCR) has outgrown its compliance roots. With the EU’s public disclosure clock ticking and jurisdictions like Australia raising the bar on public tax transparency and jurisdiction level disclosure, multinational tax departments face a new reality: data is going public, and narrative needs to be ready now.
Key Takeaways
- Country-by-country reporting will only increase in complexity — Australia’s public CbCR regime requires certain large multinational groups to publish selected information publicly. For Australia and specified jurisdictions where the group operates, this includes separate disclosure of business activities, employees, revenue, profit or loss before tax, tangible assets, income tax paid on a cash basis, current-year income tax accrued, and an explanation of why current-year tax accrued differs from tax calculated by applying the relevant jurisdiction’s tax rate.
- It is preview of where other high-scrutiny jurisdictions may be heading, and companies need to build that explanatory analysis capability now, systematically rather than scrambling later.
- There has to be a shared narrative from corporate teams —The EU’s public CbCR is a reputational event, not just a filing. So that means tax, communications, and investor relations teams need a shared narrative before the data goes public — inconsistencies create exposure you do not want to manage reactively. Australia raises similar issues because the public will see not only the explanations but also the group level and jurisdiction level figures.
- Rethink your filing jurisdiction in light of changes — If EU filing jurisdiction was chosen at initial implementation and never revisited, look again. Guidance has matured, and a more efficient or better-suited option may now be available.
Among the many pressing topics discussed in detail at the recent Tax Executives Institute (TEI) Midyear Conference, country-by-country reporting (CbCR) and its ability to reshape the corporate tax industry, certainly had its place. Between escalating local jurisdiction requirements, the European Union’s public disclosure framework, and Australia’s public CbCR regime and deeper public, jurisdiction level tax transparency, CbCR has quietly evolved from a transfer pricing filing obligation into something far more strategically consequential.
The floor is just the floor.
The creation of the Country-by-Country Reporting framework by the Organisation for Economic Co-operation and Development (OECD) was intended as a minimum standard for countries. And now jurisdictions are increasingly layering additional requirements on top of the OECD’s basic templatpre, resulting in a widening gap between the standard requirements and what tax authorities actually want.
Currently, Australia is one of the most pointed examples. Australia’s public CbCR regime is significant because it is not simply an additional private filing. Once an entity is in scope, it must provide a Public CbC report to the ATO, and the Commissioner must then make the information available on an Australian government website. For 30 June year-end groups, first reports can be due as early as 30 June 2026, with the first publication expected later in 2026. Failure to publish on time or to correct a material error on time can result in penalties, currently up to AUD825,000 (subject to future indexation).
Broadly, the rules apply to a relevant entity that had CBC reporting parent status for the relevant prior period — in general, a non-individual entity not controlled by another CBC reporting group member and with annual global income of AUD1 billion or more — where the entity is a CBC reporting group member during the reporting period, the group has the required Australian nexus, and the entity’s aggregated turnover includes at least AUD10 million of Australian-source income, subject to exemptions.
The report has three main layers:
- it must include group-level information: the reporting entity’s name, the names of other entities in the CbC reporting group, and a description of the group’s approach to tax;
- Australia and each specified jurisdiction where the group operates must be reported separately. For these jurisdictions, the report must disclose business activities, employees on a full-time equivalent basis, revenue from unrelated parties, revenue from related parties that are not tax residents of the relevant jurisdiction, profit or loss before income tax, tangible assets excluding cash and cash equivalents, income tax paid on a cash basis, current-year income tax accrued, the currency used, and the jurisdiction-specific tax-rate explanation (broadly, an explanation as to why current-year income tax accrued differs from the amount of tax that would arise if the relevant jurisdiction’s tax rate were applied); and
- • jurisdictions that are neither Australia nor specified jurisdictions can generally be reported on an aggregated basis, with no default requirement to identify each jurisdiction separately or provide a separate tax-rate explanation for each one.
This requires corporate tax departments to bridge the gap between financial statement amounts, cash tax payments, jurisdictional profits, employee and asset footprints, and the explanations that will sit beside those figures in a public report, in a way that is coherent, defensible, and consistent with positions taken elsewhere.
At the TEI event, panelists explained that for tax departments this will raise complex timing differences, deferred tax positions, or significant jurisdictional mismatches between booked and cash taxes. Indeed, this additional layer of scrutiny will need dedicated attention.
The broader signal matters: Australia may not be the last jurisdiction to move in this direction. So that means that tax departments should treat Australia’s approach as a leading indicator of where other high-scrutiny jurisdictions could be heading. Building the capability to produce this kind of explanatory analysis systematically — rather than scrambling jurisdiction by jurisdiction — would be the smarter long-term investment for corporate tax teams.
The reputational point is therefore not just that Australia requires more explanation. It is that Australia requires public disclosure of sensitive group-level and jurisdiction-level information: the group’s approach to tax, entity names, business activities, employees, revenues, profit or loss before tax, tangible assets, tax paid, tax accrued, and tax-rate explanations for Australia and specified jurisdictions. Tax teams need to be ready not only to produce the data but also to explain what the public will see.
Public CbCR in the EU: The transparency ratchet has turned
For US-based multinationals with significant European operations, the EU’s public CbCR directive has fundamentally changed the calculus. Unlike the confidential tax authority filings most corporate tax departments are accustomed to, the EU’s public CbCR rules put organizations’ jurisdictional profit and tax data into the public domain, making it visible to investors, journalists, civil society groups, and organizations’ employees and customers.
The EU framework specifies which entities trigger the reporting obligation and which entity within the group is responsible for making the public filing. That scoping analysis is not always straightforward for complex multinational structures and getting it wrong could present both reputational and legal risk.
Choosing a filing jurisdiction is not purely an administrative decision — it is a choice that affects the regulatory environment that governs the disclosure, the language requirements, the timing, and the interpretive framework that applies to data.
For US-headquartered groups, the implications extend well beyond Europe. Public CbCR data is now being read alongside US disclosures, reporting on ESG activities, and public narratives about tax governance. Inconsistencies, including those technically explainable, could create unwanted noise about the company. This is clearly another reason why the tax function should partner across the business — in this case with the communications team — to make they both are aligned to tell the CbCR story instead of being caught off guard by a journalist or an investor during an earnings call.
Questions that US multinationals should be asking
Fortunately, US multinationals with multiple EU subsidiaries are not required to file public CbCR reports in every EU member state in which they have a presence. Instead, under the EU framework, a qualifying ultimate parent or standalone undertaking can satisfy the public disclosure requirement through a single filing in one EU member state, provided the relevant conditions are met. Germany and the Netherlands have emerged as two of the more popular choices for this consolidated filing approach, given their well-developed regulatory frameworks and the depth of available guidance on what compliant disclosure looks like in practice.
The strategic implication is meaningful. Choosing a filing jurisdiction is not purely an administrative decision — it is a choice that affects the regulatory environment that governs the disclosure, the language requirements, the timing, and the interpretive framework that applies to data. Corporate tax departments that defaulted to a filing jurisdiction early in the EU implementation process should take a fresh look. Regulatory guidance has matured significantly, and there may be a more efficient or better-suited path available than the one originally chosen.
The Uncomfortable Divergence
There is a notable irony in the current environment. Domestically, the IRS and U.S. Treasury’s 2025-2026 Priority Guidance Plan reflects an explicit focus on deregulation and burden reduction, detailing dozens of projects aimed at reducing compliance costs for US businesses. Meanwhile, the international compliance environment has moved in the opposite direction, adding disclosure layers, explanatory requirements, and public transparency obligations that many US businesses cannot avoid simply because they are headquartered in the United States.
This divergence has a direct implication for how tax departments allocate resources and make the internal case for investment in international compliance infrastructure. The burden internationally is not going down — indeed, it is intensifying — and that argument is now backed by concrete examples rather than projections.
Three Things Worth Doing Now
There are several actions that corporate tax teams should consider, including:
Audit CbCR data quality with Australia’s public CbCR requirements in mind — If you cannot readily support cash tax paid, current-year tax accrued, profit or loss before tax, employee numbers and tangible assets from the relevant consolidated financial statement data — and explain for Australia and specified jurisdictions why current-year tax accrued differs from tax calculated at the relevant jurisdictional rate — that gap needs to be closed before it becomes a public reporting issue – that gap needs to be closed before it becomes a public reporting issue.
Revisit EU filing jurisdiction strategy — If your jurisdictional decision was made at the time of initial implementation and has not been reviewed since, it is worth a fresh look before the next reporting cycle.
Develop an internal narrative around public CbCR data before it circulates externally — Your company’s tax story should not be a surprise to the corporate teams involved in communications, investor relations, or ESG — and in today’s world, assuming such news stays quiet is no longer a safe assumption. While CbCR started as a tool for tax authorities, it today has become something more visible, more public, and more consequential than that — and that trajectory is not reversing any time soon.
