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 AUSkey, or to talk to your taxation professional who can do this 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
- cancel any AUSkeys linked to your ABN.
