Find out how much an ABN costs in Australia. Learn about registration fees, renewal costs, and what you need to apply for your Australian Business Number.

If you're starting a business in Australia, one of the first things you'll need is an Australian Business Number (ABN). The good news is that applying for an ABN is completely free when you do it directly through the Australian Business Register (ABR).
In this guide, we'll break down everything you need to know about ABN costs, including any fees to watch out for and how to get your ABN without paying a cent.
No. Registering for an ABN through the Australian Business Register is free. The ABR is a government service, and there is no charge for submitting your application online at abr.gov.au.
However, some third-party services and agents charge fees ranging from $50 to $150 or more to lodge your ABN application on your behalf. While these services can be convenient, they are entirely optional.
Unlike some business registrations, an ABN does not expire and does not require renewal. Once you have your ABN, it remains active as long as you are entitled to it. There are no annual fees or renewal charges.
If your ABN is cancelled due to inactivity, you can reapply for free through the ABR.
While the ABN itself is free, there are other costs associated with starting a business in Australia that you should be aware of:
Business name registration: $44 for 1 year or $102 for 3 years (through ASIC)
Company registration: $576 for a standard company registration
GST registration: Free (required if your turnover exceeds $75,000)
Domain name: Varies, typically $10-$50 per year
Business insurance: Varies depending on your industry
Applying for your ABN is straightforward:
1. Visit the Australian Business Register at abr.gov.au
2. Click 'Apply for an ABN'
3. Answer the eligibility questions
4. Provide your identity details (TFN, name, date of birth)
5. Enter your business details
6. Submit your application
Most applications are processed immediately, and you'll receive your ABN right away.
