How To Get An ABN

Apply for an ABN

Applying for an Australian business number (ABN) is free with the Australian Business Register (ABR). You can apply online below or lodge a form by mail. There are requirements that you have to meet before you can get an ABN. Your application will be refused if you are not entitled. The information you provide when you apply for an ABN must be true and correct. Once you are registered your details will be added to the ABR. It is your responsibility to keep them up-to-date.

Apply online

When you apply online the Registrar of the ABR will determine if you are entitled to get an ABN straight away. You will need the following information to complete your application.

All applicants will be asked for:

  • entity type – for example, individual/sole trader, company, super fund
  • previous Australian business number (ABN) – check on ABN LookupExternal Link to see if you are an existing ABN holder
  • tax agent number (TAN) – if you are using one
  • legal name of the entity
  • tax file number (TFN) – providing a TFN is not mandatory, but will help us identify who you are and speed up the application process
  • all business locations – physical and postal addresses
  • authorised contact details
  • main business activity.

If you are a company, partnership, trust or superannuation fund in addition to the above you may need:

  • Australian Company Number (ACN) or Australian Registered Body Number (ARBN)
  • TFN for your business – if you do not already have a TFN, you can apply during the ABN application
  • all associate details.
After submitting your application

Once you have submitted your application you will get a notification advising if:

  • you have been successful
  • your application needs further information
  • your application has been refused.

If your application needs more information or if you are refused you will be contacted by the ABR.
