What each authority actually requires, where the dependencies sit, and the places groups lose time — written out of a cycle where the rules moved while we filed.
Australia splits Pillar Two across four lodgment obligations behind an ATO access layer with its own queue. Covers the GDMT account and role, agent nomination sequencing, the GIR XML identifier rules, Section 3 of the CGDMTR, the designated local entity and its 20-entity ceiling, penalties and the transitional posture — with a ready reckoner for the sequence that worked.
By the first deadline, Irish Revenue had received just over 40 information returns, around 700 notifications and more than 600 domestic returns. That ratio is the whole picture. Includes a terminology map across six jurisdictions and a twelve-point filing matrix.
A notification carries no tax and often only a handful of data points, which is exactly why it gets missed — and where a group relies on central filing, it is the mechanism that makes the relief work. Covers Australia's foreign lodgment notification, the difference between a deferral and a suspension of enforcement, and Article 44 under DAC9.
If you have entities across several jurisdictions and cycle two is on the horizon, I am happy to talk it through.
