Instructions for completing Section 2 of the CGDMTR.

Published 31 March 2026

Before you start

Section 2 requires you to:

  • disclose details about each group entity (including the lodging entity), similar to the details requested in Section 1
  • indicate whether a foreign lodgment notification is or will be lodged for each group entity
  • show amounts payable including nil amount for each group entity.

Note: The UTPR does not apply until fiscal year starting 1 January 2025.

For more information, see Pillar Two implementation in Australia.

Applicable group entity details

If you are lodging as a standalone entity, you are only required to complete your own details.

If you are lodging as a DLE, you:

  • must complete an entry for each group entity you are lodging on behalf of, including your own details
  • will need to indicate which reporting obligations apply to each entity.

Depending on which obligations apply, you may need to report one or more of the following for each entity:

  • Foreign lodgment notification
  • IIR top-up tax amount, including a nil amount
  • DMT top-up tax amount, including a nil amount.

Note: UTPR top-up tax will apply for fiscal years starting on or after 1 January 2025.

When reporting for entities in your MNE group:

Depending on your circumstances, you may not need to report every entity within the MNE group. Refer to Lodging, paying and other Pillar Two obligations and our legislative instrument for further details regarding your lodgment obligations.

Do not include entities with a different fiscal year, such as where an entity has joined or left your MNE group during the fiscal year. The relevant entity will need to lodge separately.

Reminder: If you are lodging for more than 20 entities, seek alternative lodgment options; see Lodging, paying and other obligations for Pillar Two.

You must notify the ATO of UPE or DFE information

GIR lodged in Australia (DLE)

The DLE lodges the GIR with the ATO.

Further information

There is a default obligation on all group entities to lodge an AIUTR and DMTR, even when the entity has a nil amount. However, the Commissioner of Taxation, by legislative instrument, has specified the circumstances in which a group entity is exempt from lodging an AIUTR or a DMTR for a fiscal year.

For more information on which group entities are exempt, see LI 2025/28 Taxation Administration (Exemptions from Requirement to Lodge Australian IIR/UTPR tax return and Australian DMT tax return) Determination 2025.

Note that you do not have to list details of excluded entities.

  • Select Yes if the entity is required to lodge both an AIUTR and a DMTR.
  • Select Yes if the entity is only required to lodge one of the AIUTR or DMTR, but not both
    • this means the entity is exempt from lodging either the AIUTR or the DMTR, but not both of them
    • selecting Yes will allow you to access the relevant fields
    • you must complete each field, even if the entity is exempt from lodging that part of the CGDMTR
    • select No in the next section at the relevant field if the entity is not required to report an Australian domestic top-up tax amount or an Australian IIR top-up tax amount
    • for example, if the entity is exempt from lodging the AIUTR, select Yes to access the field. You can then select No in response to whether the entity is required to report an Australian IIR/UTPR top-up tax amount.
  • Select No if the entity is exempt from lodging both the AIUTR and the DMTR.
  • Select No if the entity is an excluded entity.
  • Select No if the entity is only lodging the foreign lodgment notification. You can amend the CGDMTR later to lodge the AIUTR and DMTR.

For more information, see Global and domestic minimum tax.

Did you indicate you need to complete an AIUTR and/or DMTR for this entity?

Australian IIR/UTPR and Australian DMT tax return.

Is this entity required to report an Australian domestic top-up tax amount (including a nil amount)?

  • Select Yes if the entity is required to lodge a DMTR for the fiscal year in respect of the MNE group. Enter the total of the entity's domestic top-up tax amounts, including a nil amount, in the space provided. The sum of these amounts is an amount of Australian DMT tax, being tax payable under section 8 of the Taxation (Multinational–Global and Domestic Minimum Tax) Act 2024 (Minimum Tax Act).
  • Select No if the entity is an excluded entity or it is exempt from lodging a DMTR. For more information, see LI 2025/28.

Is this entity required to report an Australian IIR top-up tax amount (including a nil amount)?

  • Select Yes if the entity is required to lodge an AIUTR for the fiscal year in respect of the MNE group. Enter the total of the entity's IIR top-up tax amounts, including a nil amount, in the space provided. The sum of these amounts is an amount of Australian IIR tax, being tax payable under section 6 of the Minimum Tax Act.
  • However, you can choose to select No even if the entity is required to lodge an AIUTR, if the entity's circumstances are described in paragraph 11(1)(a) of the legislative instrument. Those paragraphs describe circumstances in which an entity could never have an IIR top-up tax amount greater than nil. In these cases, you can either choose to select No, or report a nil amount at this item.
  • Select the appropriate parent entity type from the list; see Appendix 1.
  • Select No if the entity is an excluded entity or it is exempt from lodging an AIUTR. For more information about lodgment exemptions, see LI 2025/28.
