15% Global Minimum Tax: What Changes with the Technical Correction for Multinationals

Key data

Multinational groups with more than €750 million in consolidated revenues have a specific task after 26 May 2026: to verify that their tax compliance analyses are based on the corrected version of Directive (EU) 2022/2523. The correction published in the EU Official Journal does not modify the global minimum rate of 15% or the application threshold, but it does clarify formal and linguistic aspects of the official text that may affect technical interpretations.

Working with an outdated version of the directive in compliance analyses is a real risk for any group with presence in multiple European jurisdictions.

What does this regulation establish?

The Directive (EU) 2022/2523, approved by the Council on 14 December 2022, transposes the GloBE (Global Anti-Base Erosion) rules agreed within the OECD framework into European law. Its objective is to ensure that no multinational group or large national group pays tax below 15% in any EU jurisdiction.

The correction published on 26 May 2026 does not alter this mandate. It corrects exclusively technical or drafting errors detected in the original text published in Official Journal L 328 of 22 December 2022. These are formal or linguistic clarifications that, without changing the regulatory substance, may be relevant in technical interpretations and compliance analyses.

In Spain, this directive has been transposed through the Complementary Tax, which is the national mechanism to ensure that affected groups achieve the 15% minimum rate when effective taxation in any jurisdiction falls below that threshold.

Economic and operational impact

The direct impact of this correction is not economic in itself: it does not modify rates, thresholds, or payment obligations. The impact is operational and compliance-related.

Groups working with the original text of Directive (EU) 2022/2523 without incorporating this correction may be basing their analyses on a version containing formal inaccuracies. In an environment of increasing international tax scrutiny, operating with outdated technical documentation creates risk of incorrect interpretations during inspections or requests from tax authorities.

Groups with presence in multiple EU jurisdictions have an additional operational burden: they must review their tax structures to ensure that no entity pays tax below 15% in any member state, and that analysis must now be done with the corrected version of the text.

Who does it affect?

• Multinational groups with consolidated revenues exceeding €750 million with presence in the EU.
• Large national groups with consolidated revenues exceeding €750 million operating in multiple jurisdictions within the EU.
• Tax directors and CFOs of affected groups overseeing Complementary Tax compliance in Spain.
• Tax advisors who prepare GloBE compliance analyses for their clients and must incorporate the corrected version of the directive.
• Legal and compliance teams that maintain updated regulatory reference documentation.

Practical example

A multinational group headquartered in Spain with subsidiaries in Ireland, the Netherlands, and Germany, with consolidated revenues of €1.2 billion, is required to apply the GloBE rules transposed by Directive (EU) 2022/2523.

Its tax advisor has prepared a Complementary Tax compliance analysis based on the original text of the directive published in December 2022. Following the correction of 26 May 2026, that analysis must be reviewed to confirm that the formal clarifications introduced do not affect any technical interpretation used in the calculation.

If the Irish subsidiary pays tax at an effective rate below 15%, the group must apply the complementary tax mechanism to cover the difference. That calculation must be performed with the corrected version of the official text, not the original version.

What should companies do now?

1. Update reference documentation: Replace the original text of Directive (EU) 2022/2523 with the corrected version published on 26 May 2026 in all internal regulatory compliance repositories.
2. Review current GloBE compliance analyses: Tax advisors must verify that Spanish Complementary Tax analyses incorporate the corrected version and that no technical interpretation is affected by the formal clarifications introduced.
3. Verify effective taxation by jurisdiction: Groups with presence in multiple EU countries must confirm that no group entity pays tax below 15% in any jurisdiction, using the corrected text as reference.
4. Communicate the change to involved teams: Inform tax, legal, and compliance teams of the existence of this correction so they update their workflows and analysis templates.
5. Consult with your tax advisor: If there are doubts about whether the formal corrections affect any specific interpretation applied in the group, consult with an international tax specialist before filing returns or responding to requests.
