When we refer to the ancillary fund guidelines, we are referring to the Public ancillary fund guidelines 2011 as amended in June 2020 for public ancillary funds (public AFs) and the Private ancillary fund guidelines 2019 as amended in June 2020 for private ancillary funds (private AFs).

When we refer to a 'fund' in these instructions, we are referring to an ancillary fund.

When we refer to 'you' in these instructions, we are referring to you as the trustee of the ancillary fund.

These instructions are not a guide to law on ancillary funds. They sometimes refer you to a guideline that specifically addresses an item in the return you are completing. This does not mean the guideline is all you need to consider regarding that item, or the operation of the fund.

Note: Do not send the audit report and financial statements with the return unless you need to do so because of particular circumstances, such as winding up the fund or ceasing to be an ancillary fund.

Penalties may be imposed for giving false or misleading information – penalties may also be imposed for non-compliance with the ancillary fund guidelines.

Relevant period

An entity's income year for the purposes of tax law is usually the period of 12 months ending on 30 June each year.

If you do not write any dates in this field, then your organisation will be treated as having a 1 July to 30 June income year.

An entity that wishes to adopt a substituted accounting period (SAP) can only do so with the Commissioner of Taxation's approval.

If your organisation has an approved SAP, you would have been sent a letter confirming your approved SAP.

Any SAP must be approved by the Commissioner prior to lodgement of the return.


We are authorised by taxation law to collect the information on this form and disclose it to other government agencies. This includes the personal information of the person authorised to sign the declaration. For more information, see Our privacy policy.
