Notify us of a new eligible tier-1 company of a multiple entry consolidated group

How to notify us when a new eligible tier-1 company joins a multiple entry consolidated (MEC) group.

Last updated 24 November 2024

New eligible tier-1 company

The provisional head company of a MEC group must notify us if it makes a written choice to allow a new eligible tier-1 company of the top company to join the MEC group.

The provisional head company must notify us:

  • no later than the date it lodges its income tax return for the income year in which the special conversion event occurs, or
  • if a return is not required for that income year, by the date it would have otherwise been due.

We recommend the head company submits the notification 28 days before lodging its income tax return. This will allow us to update our records for the group and ensure the return is processed correctly.

How to notify us

The public officer of the head company, as listed in the Australian Business Register (ABR), or its registered tax agent must notify us that the new eligible tier-1 company has joined the group, using a Notification of a new eligible tier-1 company of a multiple entry consolidated (MEC) group (NAT 73442, PDF 355KB)This link will download a file form.
