Update your ABN details

It's your responsibility to maintain your Australian business number (ABN) details.

You must update your details within 28 days of becoming aware of changes.

The fastest way to update your details is online using myGovID, AUSkey or Manage ABN Connections. All changes made to your ABN online will take effect immediately.

AUSkey and Manage ABN Connections will be retired at the end of March 2020. myGovID and Relationship Authorisation Manager (RAM) are simpler and more secure way to login. Find out if you're ready to start using myGovID and RAM.

  • business names

Name changes made by the ATO and ASIC will update the ABR.

If you're unable to update details using the above link, contact us or lodge a form by mail.
