Streamline, automate, and ensure compliance for the new standard of financial presentation.

Why it matters: Strategic reporting challenge

• P&L Structure Rework: Companies must overhaul existing income and expense classifications, add two new defined subtotals to the P&L, and design new reporting systems and processes.
• Increased Data Granularity: Meeting presentation requirements demands capturing and categorising financial data at a more detailed level.
• Auditability & Control Pressure: Providing clear, fully traceable reconciliations (especially for MPMs and comparative periods) will place heavy strain on data integrity and internal controls.
• Risk of Manual Errors: Relying on manual adjustments and disconnected systems makes compliance slow, cumbersome, and risk-prone.

❓Why Act Now? Companies that start early can optimise data readiness, minimise manual rework, and future-proof their reporting.

Implementing IFRS 18

Partner with Workiva and seamlessly connect your ERP and consolidation systems into a single collaborative hub. It centralises your reclassification logic, making the transition controlled and audit-ready while streamlining the process for multi-entity reporting.

Here’s how we help you today:

• Automate and Standardize Reporting with Dynamic Table Management: Modernize your financial disclosures and handle complex dual-framework reporting (such as IAS 1 and IFRS 18) with complete control. Using Range Linking, seamlessly push structural additions, row/column edits, and restatements across all entity tables in a single click. Pair this with Enhanced Table Filters to automatically show, hide, or bulk-reapply formula-driven rows (like zero-sum balances), and lock in audit-ready consistency across MPM footnotes and disaggregation tables using centralized Value Format Styles.
• Remapping the Chart of Accounts with Wdata: Solves the challenge of data granularity by extracting "nature of expense" data (e.g., inventory write-downs) that may be buried in functional ERP lines. It automates reclassification logic with full traceability. (Ask your Workiva representative about how to use Wdata, or start here.)
• Workiva AI: Leverage Workiva AI to help evaluate your current Annual Report, supporting your team in identifying potential disclosure and structural updates for IFRS 18 compliance.

📝 Note: Please always consult your external auditor for legal and accounting advice regarding your IFRS 18 compliance.

ESEF Taxonomy Roadmap & Guidance

Understanding your XBRL/ESEF tagging strategy is critical as you prepare your reporting frameworks:

• Available ESEF 2025 Options: Filers have two available taxonomy options:

  • ESEF 2025 (IAS 1)

  • ESEF 2025 (IFRS 18 EA) — designed for early adopters.

• One-Way Migration Rule: Migration between these taxonomies is strictly a one-way process. You can migrate from ESEF 2025 (IAS 1) to ESEF 2025 (IFRS 18 EA), but reverting from IFRS 18 back to IAS 1 is not supported.

• Workiva Recommendation: Because migration cannot be undone, we strongly recommend that all non-early adopters select ESEF 2025 (IAS 1) for this reporting cycle. Once IFRS 18 becomes mandatory next year, you will be able to migrate smoothly from ESEF 2025 (IAS 1) to ESEF 2025 (IFRS 18).

• Mandatory Effective Date: The 2025 ESEF Taxonomy becomes mandatory for all financial years beginning on or after 1 January 2026.

• Previewing the Taxonomy: Filers planning to adopt early should use the Taxonomy Analyzer in Workiva to thoroughly inspect and review the IFRS 18 EA structure before executing any migration.

❗ Important Consideration: Once a document is migrated to ESEF 2025 (IFRS 18 EA), reverting back to IAS 1 is not supported. Ensure your reporting team, external auditors, and local regulatory requirements are fully aligned before initiating the migration.

🔔 Reminder: Always confirm your specific requirements, timeline, and filing acceptance rules with your local National Competent Authority (NCA) and external auditors before proceeding.
