You should cancel your ABN if your business:

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

Before you cancel your ABN


Before you can cancel, you’ll need to meet the lodgment, reporting and payment obligations for all the government agencies you deal with. It is recommended you wait to cancel your ABN until all processes are completed.

Your business might need to:

  • lodge activity statements
  • lodge pay as you go (PAYG) withholding reports
  • repay goods and services tax (GST) credit refunds
  • pay outstanding tax debts

Other registrations will be cancelled

Be aware that cancelling your ABN will also cancel your registration for:

  • any representative holding a login credential for your business. This may prevent you from using some government online services
  • GST, luxury car tax (LCT), wine equalisation tax (WET) and fuel tax credits (FTC)

Cancel your ABN

You can cancel your ABN online through the Australian Business Register.

Before you cancel, check:

  • you’ve met the lodgment, reporting and payment obligations for all the government agencies you deal with and that all processes have been completed.

Note: If you want to cancel your pay as you go withholding, you must cancel it before you cancel your ABN.

If you can’t cancel your ABN online

There are other options available to cancel your ABN.

  • Call the Australian Business Register on 13 92 26 between 8am and 6pm, Monday to Friday. You must be recorded as authorised to update ABN details for your business. You’ll also need to prove your identity. It’s a good idea to have your tax file number (TFN) handy to do this.
