If you’re looking to become self-employed in Australia, getting an ABN (Australian Business Number) is one of the first legal steps. Whether you’re a freelancer, tradesperson, rideshare driver, or launching a small business, an ABN is essential to operate legally, issue invoices, and claim tax deductions.
What Is an ABN?
An ABN is an 11-digit number issued by the Australian Business Register (ABR) that identifies your business operations to the government, clients, and the Australian Taxation Office (ATO). It’s essential for:
- Invoicing and getting paid
- Registering for Goods and Services Tax (GST)
- Opening business bank accounts
- Applying for business name registration
Who Needs an ABN in Australia?
You’ll need an ABN if you’re:
- A sole trader, freelancer, or consultant
- A tradie, contractor, or delivery driver (Uber, food delivery etc.)
- Launching a side hustle or online business
- Running a partnership, company or trust
- Registering for GST or working in the Fly-In Fly-Out (FIFO) sector
Tip: If you’re applying for entry level FIFO jobs, having an ABN may be required for certain subcontracting roles or services.

- Sole Trader – Common for freelancers and one-person businesses

Fill out:

- Description of your business activities
- Business and mailing address (can be your home)

The process is free, takes around 15 minutes, and in most cases, your ABN will be issued instantly if your details match ATO records.
Required Documents for ABN Application
To complete your Australian ABN application, ensure you have:
- Personal ID details (e.g., name, DOB)
- TFN (Tax File Number)
- Business activity description
- Email and phone contact
- Business address (even if home-based)
How Long Does It Take to Get an ABN?
- Instant approval in most cases
- Up to 28 days if your application requires review by the ATO
Why Do You Need an ABN?
Having an ABN allows you to:
- Legally invoice clients
- Avoid having tax withheld at the highest rate
- Register for GST if your business earns over $75,000/year
- Build business credit and credibility
- Claim legitimate business expenses on your tax return
ABN vs TFN: What’s the Difference?
- TFN (Tax File Number): Personal number for employees and individuals
- ABN: Business number for anyone earning income from business activity
You may need both if you’re working as an employee and running a business.
Is an ABN Safe to Share?
Yes. Your ABN is public information and is typically displayed on:
- Invoices
- Business cards
- Websites
- Emails
However, never share your TFN, which is private.
Can You Cancel or Update Your ABN?
Yes. Use the ABR website or your myGovID account to:
- Cancel your ABN if you’re no longer trading
- Update your contact details
- Change your business structure
Common Mistakes to Avoid
- Applying with incorrect details (e.g., mismatched TFN info)
- Forgetting to update ABN details when your business changes
- Using your ABN to avoid employment obligations
Note: If you’re in FIFO mining jobs with no experience and work on a contract basis, confirm with your employer whether an ABN is required for your position.
