Only purchasers complete and lodge these forms.

A purchaser can authorise a representative to lodge the forms on their behalf by giving them a signed declaration.

Representatives can include conveyancers or solicitors.

Declaration for representative

Purchasers can authorise a representative to complete and lodge the forms on their behalf by completing a signed declaration. The declaration states that:

  • you have authorised your representative to lodge the form
  • the information in the form is true and correct
  • if your representative is a conveyancer, you're aware they
    • aren't a registered tax or BAS agent or Australian legal practitioner
    • can't provide tax agent or legal services.

You can give this declaration to your representative in email, fax or paper form. You need to keep the declaration (or a copy) for up to 5 years. We recommend your representative also keeps a copy of the declaration for their own records. Paper declarations can be scanned and stored electronically.

Note: Don't send your declaration to us unless we ask for a copy.

Penalties may be imposed for giving false or misleading information.

Acting as a representative

If you're acting as the purchaser's representative, you need to understand your obligations under the Tax Agent Services Act 2009 (TASA).
