Business Registration
ABN Registration
Check what an Australian Business Number is used for and the business details usually needed before applying.
Overview
ABN Registration explained
ABN registration gives you an Australian Business Number, the identifier the Australian Business Register issues so your business can be recognised in dealings with the ATO, other businesses and government. It is the foundation most other registrations build on.
Your ABN appears on invoices, lets others verify you, and helps you avoid having tax withheld at the top rate. To apply, you confirm you are genuinely carrying on a business and provide details about who you are and what you do.
Cockatoo helps you check whether you are entitled to an ABN and gather the details before you apply, so the registration goes smoothly.
What to check
Key points
- An ABN is issued by the Australian Business Register, not by ASIC.
- It is used on invoices and lets other businesses verify who you are.
- Having an ABN can prevent tax being withheld from your payments.
- You must be carrying on or starting an enterprise to be entitled to one.
Before you start
What you'll need
- Proof you are carrying on or about to start a business or enterprise.
- Your tax file number and identity details for each owner.
- Your business structure: sole trader, partnership, company or trust.
- A description of the main business activity you will carry out.
- Contact, address and business commencement details.
- An ACN already in hand if you are registering for a company.
Process
How it works
- Confirm you are entitled to an ABN by genuinely carrying on an enterprise.

Avoid these
Common mistakes
- Applying for an ABN when you are not actually carrying on a business.
- Confusing the ABN with an ACN, which only companies receive from ASIC.
- Describing the business activity vaguely, which can slow the application.
- Letting ABN details go stale instead of updating them when things change.
Common questions
ABN Registration FAQs
What is an ABN used for?
An Australian Business Number identifies your business in dealings with the ATO, other businesses and government. It appears on your invoices, lets clients verify you, and helps avoid tax being withheld at the top rate when you are paid. Most other registrations rely on it.
What details do I need for ABN registration?
You need your tax file number, identity details, your business structure, a description of your main activity, and contact and address information. If you are registering for a company, you will also need the ACN that ASIC has already issued.
Who is entitled to an ABN?
You are entitled to an ABN if you are carrying on or starting an enterprise in Australia. A hobby or one-off private sale generally does not qualify. The application asks questions to confirm genuine business activity, so be ready to describe what you do.
Is an ABN the same as an ACN?
No. An ABN is issued by the Australian Business Register for all business types, while an ACN is issued by ASIC only to companies. A company holds both, and its ABN is usually based on its ACN, but a sole trader has only an ABN.
