Updated information about global and domestic minimum tax

Our updated website has more details on the rules, potential law amendments and interactions with other provisions.

Published 16 May 2025

We’ve published updates on our website about key aspects of the global and domestic minimum tax.

The updates follow on from the royal assent of the primary legislation, and the subordinate legislation being registered as a legislative instrument.

Our website information is designed to help taxpayers who may be in-scope of Pillar Two to meet their obligations, as first lodgments are due by 30 June 2026.

The global and domestic minimum taxes are a key part of the Organisation for Economic Co-operation and Development's coordinated global approach to prevent a 'race to the bottom' on corporate tax rates.

What the website updates cover

Our website information now includes:

  • guidance about how we'll administer potential amendments to Australian law to address inconsistencies
  • an overview of the mechanics for calculating top-up tax
  • additional information on how the rules apply, including in respect of specific entities
  • additional information and examples about lodgment, payment and record-keeping obligations
  • how Pillar Two interacts with other provisions and how it applies.

 

Moving forward

Through our consultation with the Pillar Two Global and Domestic Minimum Tax Working Group, we've been considering the need for, and prioritising the development of, formal and informal guidance for the market. We're also updating existing guidance that may be affected by the introduction of this measure.

We'll continue to update our website with more information over the coming months.
