The GloBE deadline calendar: setting project milestones that hold

Pillar 2 deadlines are hard, but projects usually fail not on the deadline itself but on the missing buffer before it. From a management view, what matters is not the GIR filing date but the dates by which input data must be ready.

From regulatory deadline to milestones

For many groups the first GloBE Information Return for FY2024 falls on 30 June 2026. That is an end date - not the date you plan work towards. A sensible schedule works backwards from it:

T-0: GIR filing.
T-4 to T-6 weeks: data freeze, quality review, final validation.
T-3 to T-4 months: complete consolidation and tax data from one source.
T-6 months and earlier: source map, data owners, policies (FX, asset base).

Three risks worth putting on the register

Third-party dependencies - data from advisors or local entities whose timing you do not fully control.
Structural changes during the year that must be reflected in the entity register.
Policy inconsistency between jurisdictions that only surfaces at aggregation.

Takeaway. The regulatory deadline is one date on the calendar. A project runs on the milestones that come earlier - and those decide whether 30 June is calm or chaotic.
