An AUSkey is a unique secure login linked to an Australian business number (ABN) which allows the Australian Government to identify you and the business you're representing. You'll need an AUSkey if you ever need to conduct transactions for a business you represent such as:

  • updating the details of an ABN
  • conducting transactions via the BAS Agent Portal, or Business Portal.

A standard AUSkey will also allow you to:

  • manage your own AUSkey
  • obtain additional AUSkeys to use on other computers
  • manage a Device AUSkey if you are the custodian.

If you'd like to apply for a standard AUSkey you can do this online.


Anyone can register for a standard AUSkey providing they know the email address of the AUSkey Administrator.

An email will be sent to the AUSkey Administrator requesting their approval. It is the AUSkey Administrator who will determine if you are suitable to represent the business.
