The first GIR filing season revealed just how complex Pillar Two compliance can become in practice.

Data collection requirements were often underestimated. Pillar Two-specific data required significant manual input and transformation. GloBE and ACT adjustments needed local analysis and validation, while filing requirements, validation rules and file formats differed across jurisdictions.

And the GIR itself is only one part of the process: multinational groups must also coordinate local notifications, QDMTT requirements and increasingly tight filing timelines.

So, what can Tax and Finance teams learn from the first filing cycle, and what should they prepare differently for the next one?

During this live webinar, Taxvibes and kShuttle, together with our clients, will share practical lessons from the first GIR filing season and explore how a more structured approach can help organisations prepare earlier, strengthen data quality and reduce manual rework.

The session will combine technical filing insights, customer feedback and a live demonstration, covering the journey from source data to validated, filing-ready outputs.
