On 27 October 2026, the OECD published the revised user guide for the GloBE Information Return (GIR) XML Schema, version 2.0, as part of the BEPS Pillar Two implementation framework. The GIR is the standardized electronic reporting mechanism for Multinational Enterprise (MNE) groups to disclose their Global Anti-Base Erosion (GloBE) calculations to tax administrations. The revised schema incorporates feedback from the public consultation held in Q2 2026 and aligns with the final Commentary to Article 8.1 of the Model Rules released in July 2026. Key updates include enhanced validation rules for jurisdictional effective tax rate (ETR) calculations, new data elements for Transitional CbCR Safe Harbour elections, and improved error handling for constituent entity reporting. The schema is mandatory for fiscal years starting on or after 31 December 2026.
Key Takeaways
- Enhanced ETR Calculation Validation: The schema now includes mandatory fields for the Substance-based Income Exclusion (SBIE) components — payroll and tangible asset carve-outs — with cross-referencing to Country-by-Country Report (CbCR) data. This ensures consistency between GIR and CbCR filings and reduces query risks from tax authorities.
- Transitional CbCR Safe Harbour Data Elements: New optional fields allow MNEs to report qualifying revenue, profit, and ETR thresholds for the three safe harbour tests (de minimis, simplified ETR, and routine profits). Accurate reporting enables tax administrations to verify safe harbour eligibility without additional information requests.
- Improved Error Handling and Constituent Entity Mapping: The schema introduces standardized error codes for common validation failures, such as mismatched GloBE IDs, inconsistent currency conversions, and missing constituent entity types. A new “Entity Classification” field distinguishes between Ultimate Parent Entities, Intermediate Parent Entities, and Permanent Establishments, facilitating automated processing.
