Register your ABN in under 5 minutes

An Australian Business Number (ABN) is a unique 11 digit number which the ATO will allocate to you. This number is used on your business documents and invoices

You need an ABN to receive all B2B payments, to register for PAYG and GST and to register a .com.au domain and business name(s). Having an ABN will also enhance the legitimacy of your business

You are entitled to an ABN if you are carrying on an enterprise in Australia, a company or making supplies connected with Australia’s indirect tax zone.

You will need to provide the following information when applying for your ABN:

• Proof of identity
• The reason you are applying for an ABN
• The date you require the ABN to be effective from
• Your Tax File Number (TFN)
• Where your business is located
• Details of any officeholders in your business
• The industry your business will operate in
• The activities your business will engage in

Your ABN may be delayed if:

• There are problems with the verification of your identity,
• You have an overdue tax return,
• Already have applied for an ABN, or
• A previous application has been rejected.

If your application has been rejected, you have the option to dispute it within 60 days. You should detail why you are objecting to the decision and provide supporting documentation. Please note that we do not provide refunds for rejected applications.
