Lodgment deferrals

Every in-scope taxpayer will be granted an automatic 30-day deferral for their AIUTR and DMTR lodgments for fiscal years starting in 2024. This allows additional time to prepare and lodge Pillar Two obligations.

The lodgment deferral automatically appears on the account. You do not need to apply for this deferral.

This automatic deferral doesn't apply to later fiscal years commencing after 2024.

For more information, including how to request deferrals for longer periods or future years, see Lodging, paying and other obligations for Pillar Two.
