How to add an ABN to a business name holder

Select the 'Lodgements & Notifications' tab at the top of the screen.

  • Select the business name you wish to add the ABN to.
  • In the transactions column, select 'Add ABN'.
  • Select 'Go' to continue.


Enter your ABN in the field provided, ensuring it contains 11 digits and no spaces.

We will verify your details with the Australian Business Register (ABR). If the details for the holder type (e.g. individual or partnership) on the ABR are different to those held by ASIC, you will not be able to proceed.

  • Select 'Next' to continue.

After you have entered your ABN, check that the information returned from the ABR (name of holder and holder type) matches the information held by ASIC. 

  • If the information from the ABR is incorrect, check that you have entered the correct ABN.

Note: If the details returned from the ABR differs from those held by ASIC, you will see an alert box.

You should double check the ABN you have entered is correct. If it is, and you're confident the name of the holder is true, select 'Next'. If the information held by ASIC is incorrect – but the information from the ABR is correct – selecting 'Next' and completing the transaction will automatically update your details on ASIC's registers.

Please note you cannot use this transaction to change the business name holder. For more information about this, see Transfer a business name.
