Public CbCR readiness: Aligning strategy, systems and stakeholder engagement

Public CbCR: It’s time to consider how to navigate the reporting requirements and prepare for disclosure

As the first European Union (EU) Public Country-by-Country Reporting (CbCR) deadline in Ireland approaches, tax transparency is entering a new chapter — one shaped by public scrutiny, regulatory complexity, and accelerating digital capabilities. With AI-driven analyses and cross-framework comparisons becoming the norm, large multinational groups must prepare for an unprecedented level of public insight into their tax affairs. This article explores how to navigate the evolving Public CbCR landscape, from local filing complexities to aligning with broader disclosures in the tax field.

Public CbCR: A new lens on global tax footprints

CbCR is evolving from a routine compliance report into a dual-purpose instrument of tax administration and public transparency. The Organisation for Economic Co-operation and Development’s (OECD) CbCR framework has matured into a critical tool for tax authorities while public requirements such as the EU’s Public CbCR opens a new chapter in which disclosed data serves investors and the wider public by illustrating multinational enterprises’ (MNEs) tax practices.

Under EU Directive 2021/2101, large MNEs with annual consolidated revenues exceeding €750 million in two consecutive years must publicly disclose jurisdictional financial data, allowing stakeholders to better understand where profits are made and taxes are paid. The rules apply both to EU-headquartered MNEs and non-EU-headquartered MNEs with significant EU operations, including subsidiaries and/or branches. Based on the EU rules, the directive had to be transposed into local law by each EU member state. This has led to a situation whereby local rules can differ in scope, timelines, and format. This means that compliance may not be a single EU‑wide filing exercise, but a set of country‑by‑country obligations that need to be assessed and planned for strategically.

Ireland has implemented the directive with effect for financial periods starting on or after 22 June 2024. For Irish MNEs (and MNEs with Irish subsidiary and/or branches) with a December year-end, the first public reports will be due by 31 December 2026. While Ireland’s approach is broadly aligned with the directive, other EU member states such as Romania and Croatia have adopted earlier regimes, accelerating reporting timelines, while some countries (e.g. Germany, Belgium, etc.) implemented the directive with some differences which can make compliance more challenging.

The directive’s publication requirement (within 12 months of the financial year-end, as per the Irish implementation) means timing and administration are critical. As Public CbCR becomes a publicly accessible dataset, it offers a new, albeit imperfect, window into the global tax footprint of large MNEs.

This article highlights the key aspects to consider, with the following sections unpacking some of the related nuances.

Navigating local Public CbCR requirements

Publishing a Public CbCR report in one EU member state does not automatically satisfy obligations across the EU. Local transpositions of the directive can trigger separate requirements, particularly for EU subsidiaries and/or branches of non-EU headquartered MNEs.

In some jurisdictions (e.g. Italy, Denmark, etc.) local publication or filing is mandatory. These variations mean that MNEs may need to take multiple actions to ensure full compliance. Careful review of each jurisdiction’s implementation is essential to avoid oversight.

Beyond Italy and Denmark, other member states also impose distinctive requirements. In practice, this can include shorter local deadlines (e.g. Spain is 30 June), mandatory local filings irrespective of central publication, and the use of jurisdiction lists that go beyond the directive’s minimum (e.g. Belgium). Consequently, a structured, jurisdiction‑by‑jurisdiction assessment is essential.

Given differences in local implementations and the potential risk if incorrect data is included in the public disclosures, commencing a strategic review as soon as possible is imperative.

Content, format, and challenges

EU Public CbCR requires disclosure of six key datapoints:

• Total revenue;
• Number of employees (FTE);
• Profit or loss before tax;
• Income tax paid;
• Income tax accrued in the current year; and
• Accumulated earnings.

While these terms may appear familiar, their definitions can differ from how they are presented in other financial or tax disclosures. Practical approaches to definitions are therefore important to ensure consistency and, given the limited guidance on these, businesses should adopt a pragmatic approach from the outset to avoid inconsistencies and risk of misinterpretation.

All EU member states require structured, machine‑readable formats (e.g. XHTML/inline XBLR) which enable third parties to use, analyse (especially using AI) and benchmark disclosures more easily.

The data in the Public CbCR could be misunderstood or misinterpreted, particularly where timing differences, jurisdictional aggregation, or different accounting frameworks (e.g. IFRS or another applicable GAAP) affect how amounts are derived. In our experience, reviewing the disclosures from a public stakeholder perspective before release is highly beneficial to identify areas that may need additional supporting disclosures (e.g. concise descriptions, methodological notes or clarifying narrative) to explain recognition or measurement differences. It can be expected that EU Public CbCR reports will be widely reviewed and benchmarked, attracting attention from media, investors, and civil society. Conducting practical sensitivity analyses can surface potential areas where additional explanation may be beneficial and help ensure the published data is intelligible and appropriately contextualised.

Additionally, for in‑scope subsidiaries and/or branches of non‑EU‑headquartered MNEs, meeting the requirements may lead to an increased compliance burden. Where the non‑EU headquartered MNE does not publish the data necessary for the report, complexities escalate because the rules of each EU member state with qualifying operations need to be considered. As mentioned, given individual EU member states may have transposed the directive slightly differently, multiple local publication or filing mechanics may need to be applied at the same time. In situations where local operations report “based on information available”, it is extremely important to engage with the requirements, systems, and the specific rules early to ensure compliance.

To support this process, our EU Public CbCR tracker can be used to monitor and compare differing jurisdictional rules across the EU.

Bridging EU Public CbCR, OECD CbCR, Australian Public CbCR, and qCbCR

While EU Public CbCR, OECD CbCR, Australian Public CbCR, and qualified CbCR (qCbCR) share similar data requirements to a certain extent, they differ in scope, audience, etc. from multiple aspects. MNEs already preparing OECD CbCR can consider leveraging existing process documentation, controls, and governance structures to support Public CbCR readiness across the various regimes. Aligning internal controls across all frameworks to the extent possible helps reduce duplication, manage reputational risk, and ensure consistency. Establishing a unified governance model and clear ownership of data across tax and finance functions is a practical step toward integrated compliance. Furthermore, engaging with your investor relations team due to the public nature of the website publication requirement is an additional aspect to consider.

Penalties and enforcement considerations

While the directive leaves enforcement to individual EU member states, most (including Ireland) have introduced penalty regimes for non-compliance.

In Ireland, administrative fines may apply for failure to publish the report within 12 months of the financial year-end, or for incomplete or misleading disclosures. Beyond financial penalties, the public nature of the report introduces reputational enforcement through wider stakeholders and media.

Positioning tax disclosures within an evolving transparency landscape

Tax transparency is becoming a defining element of corporate responsibility, and it’s against this backdrop that Public CbCR is being introduced. Public CbCR will heighten scrutiny of how much tax MNEs pay and where, which could lead to external stakeholders forming their own views on the tax affairs of a company and their approach to tax. This creates a clear imperative for companies to supplement mandatory disclosures with meaningful narrative that gives context to the data reported, their approach to tax, and the tax governance framework that underpins it.

There is also an opportunity for MNEs to broaden stakeholder understanding of their wider tax contributions. Public CbCR only focuses on corporation tax, yet companies are subject to other taxes. By voluntarily disclosing information on their total tax contribution, which presents a more holistic view of taxes borne and collected across people, profit, product, property, and planet taxes, companies can provide visibility of their wider contribution to public finances. Based on PwC 29th Annual Global CEO Survey, in which 66% of CEOs report declining stakeholder trust, transparent and credible tax reporting has become essential to safeguarding reputation and sustaining investor confidence. Taking a considered approach to Public CbCR is therefore critical for companies. It also presents a timely opportunity for heads of tax to shape their tax transparency strategy and reposition the tax function as a strategic contributor to long-term value and sustainability.

Key actions businesses can take today

1. Map your Public CbCR obligations

• Confirm the €750 million threshold (in two consecutive years).
• Identify if an EU‑incorporated ultimate parent entity exists, or assess EU subsidiaries (medium/large) or branches that could trigger obligation where there is a non‑EU parent.
• Note start dates (implementation dates and first reporting periods may vary by EU member state).
• Check member state-specific mechanics (e.g. website availability period, language, penalties, etc.).

2. Check and align definitions and data sources early

• Consider applicable definitions for each required datapoint. These may differ from internal or statutory reporting conventions.
• Clarify how figures will be derived under your group’s accounting framework and ensure consistency across jurisdictions. Where needed, prepare narrative notes to explain timing mismatches or anomalies.

3. Centralise CbCR ownership, timelines, and governance

• Establish clear ownership across tax, finance, and legal; set early data request timelines (particularly for non-EU-headquartered MNEs); and centralise preparation while accommodating Irish and other EU local publication/filing mechanics. Ensure governance is built in so process, responsibilities, timeline, review gates, and formal sign‑off are clearly defined.
• Review where existing OECD CbCR and qCbCR processes, controls, and governance can be leveraged to drive consistency and reduce duplication/manual effort.

4. Prepare for public disclosure and scrutiny

• Robust sensitivity analysis and supportive narrative is important.
• Run pre-publication ratio and variance checks and draft clear activity descriptions and explanatory notes to reduce misinterpretation.
• Consider adding voluntary quantitative disclosures on your total tax contribution, beyond corporate income tax, to demonstrate the company’s full societal contribution.
• Complement your quantitative disclosures with qualitative disclosures on your organisation’s approach to tax and tax governance.
• Coordinate with investor relations and corporate communications in you organisation to align messaging and plan responses to likely questions.
