When should you cancel your ABN

You should cancel your ABN when your business:

• has been sold
• has closed down
• is no longer operating in Australia or making supplies connected with Australia.

You may also need to cancel your ABN if your business structure has changed.

If your business operation has ceased you must update your details or cancel your ABN within 28 days.

The fastest way to cancel your ABN is online using myGovID. Your myGovID needs to be linked to your ABN using Relationship Authorisation Manager (RAM). Alternatively, your taxation professional can cancel your ABN on your behalf.

Cancelling your ABN will:

• cancel your taxation registrations such as goods and services tax (GST), luxury car tax, wine equalisation tax and fuel tax credits
• remove any authorised relationships between a myGovID and your ABN.

To cancel you can also contact us or lodge a form by mail.
