Everything you need to know about starting and registering your Australian business

What is an ABN?

Australian Business Number - Your business identity

An Australian Business Number (ABN) is a unique 11-digit identifier for your business. It's issued by the Australian Business Register (ABR) and is essential for most business operations in Australia. Your ABN identifies your business to the government, other businesses, and the Australian Taxation Office (ATO).

Do I need an ABN?
You need an ABN if you're running a business in Australia, want to register for GST, or plan to hire employees. Even if you're a sole trader working part-time, an ABN helps establish credibility and is often required by clients.

Why You Need an ABN

Business Identity

Your unique 11-digit identifier that shows you're running a legitimate business in Australia

Required if you want to register for GST and claim GST credits on business purchases

Invoice Compliance

Common Questions

Typically, you'll receive your ABN within 1-2 business days after submitting your application. In some cases, it can be instant if all your details are verified immediately. Our service ensures your application is completed correctly the first time to avoid delays.
Applying for an ABN directly through the ABR is free. However, our service fee covers expert assistance, compliance checking, GST registration if needed, business name registration, and ongoing support to ensure your application is completed correctly.
Generally, you only need one ABN per business structure. However, if you operate multiple businesses with different structures (e.g., a sole trader business and a separate company), you'll need an ABN for each entity.
ABNs don't expire, but they can be cancelled if your business structure changes or you stop operating. You must keep your ABN details up to date, including your business location and contact information.
