Do I need an ABN to run my small business?

Navigating the world of small business can be exciting but also overwhelming, especially when it comes to the nitty-gritty of legal requirements. One question we often encounter is: Do I need an Australian Business Number (ABN) to run my small business?  In this blog we explore this question to help you understand what you need for your small business along with additional insights into business name registration, trademarks and the transition from sole trader to company. 

What is an ABN? 

An Australian Business Number (ABN) is a unique 11-digit identifier that makes your business recognisable to the government and others. It’s not just a number; it’s your business’s entry ticket into the formal economy, allowing you to collect Goods and Services Tax (GST) - provided your business is registered for GST (remember for GST registration, you can register at any time but becomes a requirement if you hit the threshold which at time of writing is $75,000AUD or more in turnover), claim tax credits, and much more.  An ABN also allows you to claim tax credits, facilitate smoother transactions with other businesses, and more. 

Applying for an ABN is a fairly straightforward and free process. Applications can be made online through the Australian Business Register (ABR) website. It’s important to have all the necessary information on hand to ensure a smooth application process. 

ABN is not the same as a Business Name 

It's crucial to understand that an ABN is different from a business name. While an ABN identifies your business operations to the government and the community, a business name is the name under which your business operates and is known to your customers. Registering a business name is a separate process handled by the Australian Securities & Investments Commission (ASIC) and does involve a fee. It's essential for businesses that operate under a trading name different from their own name or if the business is a partnership, trust, or company wishing to trade under a name not identical to the legal entity's name.  For more details on how to register a business name go to ASIC’s website. 


Did you know?   

A single ABN can be linked to multiple business names, allowing for diverse operations under one legal umbrella. This flexibility supports business owners in branching out into various ventures or market niches without the need for separate ABNs for each new operation. It's an efficient way to manage multiple facets of your business while maintaining streamlined legal and tax reporting. 


Case Study: Creative Graphix Pty Ltd trading as Creative Graphix 

David Smith runs a successful graphic design business known as "Creative Graphix". To establish a professional presence and to reduce his personal liability, David decided to set up a company "Creative Graphix Pty Ltd". While "Creative Graphix Pty Ltd" is the company's legal name and a separate legal entity, David wanted to trade publicly under a more casual and market-friendly name — "Creative Graphix". To do so, he registered "Creative Graphix" as a business name with ASIC, linked to his company's ABN.  Recognising the value of his unique brand, David was proactive in ensuring the name "Creative Graphix" was not only available but also protected; he registered it as a trademark. 


This case illustrates several key points: 

Business Name vs. Company Name: "Creative Graphix" operates as the business name, the public-facing identity under which David's graphic design services are offered. "Creative Graphix Pty Ltd", on the other hand, is the company name, denoting the business's legal entity. The distinction clarifies that while "Creative Graphix" is used for branding and marketing, all legal and formal business dealings are conducted under "Creative Graphix Pty Ltd".  David did not need to register the business name “Creative Graphix” if he planned to carry on business as Creative Graphix Pty Ltd. 

Multiple Business Names: David could decide to expand his services under different brand names, such as "Innovative Web Design" or "Dynamic Branding Solutions", and register these as additional business names under the same ABN provided by "Creative Graphix Pty Ltd". This strategy allows for business growth and diversification without needing separate legal entities for each venture. 

Trademark Protection: Registering a business name with ASIC does not grant exclusive rights over that name. By trademarking "Creative Graphix", David secured legal exclusivity, protecting his brand and distinguishing it from competitors. This step is crucial for any business aiming to build a strong, recognisable brand. If you want to know more about the difference between a business name and a trademark, then check out our blog “Trademark or Business Name?  What’s the difference”. 

Registration Necessity: If a company wants a business name that differs from its company name, it must register this name with ASIC. Otherwise, it needs to operate under its legal designation (e.g., "Pty Ltd"), ensuring transparency and legal compliance. 


Understanding the nuances between business names, company names, and the importance of trademarks is essential for navigating the Australian business landscape. These measures not only ensure legal compliance but also fortify a business’s brand identity and market position.

When You Might Not Need an ABN 

It’s Just a Hobby… Or Is It? Sometimes, the lines between a hobby and a business can blur faster than your morning smoothie. If your activities are for personal enjoyment and you’re not pursuing profit, you may not need an ABN. However, tread carefully; if your hobby starts to look a lot like a business, it’s time to get that ABN. 

How to Get an ABN 

Taking the Leap: Securing an ABN is simpler than you might think. Here’s how: 

  • Eligibility Check: Ensure you’re eligible — running a business in Australia is a start. 
  • Apply Online: Visit the Australian Business Register website to apply. It’s free and can be done in under an hour. 
  • Provide Information: You’ll need to furnish details about your business, including your business structure, location, and activities. 

ABN vs. ACN: What’s the Difference? 

A lot of people get confused between what is an ABN and ACN so we thought to break it down for you.  You’re welcome😊 
While they might seem similar, they are both unique an ABN and an Australian Company Number (ACN) serve different purposes. An ABN identifies your business in the broader market and with the government its a must have for all business structures, including sole traders, partnerships and companies. An ACN, on the other hand, is specifically for companies and comes with a 9 digit number issued by the Australian Securities and Investment Commission (ASIC) and is required when registering a company in Australia. Think of your ABN as your business’s public identity and your ACN as its corporate fingerprint.  It is worth flagging that you dont need an ACN to operate your business its only if you choose to register your business as a company that you must register for an ACN. 

Registering for an ACN 
The process for registering for an ACN involves a bit more complexity and requires registration with ASIC. You must first register for an ACN before getting your ABN.  Once your company is registered, it is treated as a separate legal entity and is subject to a number of governance rules and obligations. This status allows a company to enter into contracts and hold assets in its own name, marking a significant legal distinction that is more than just a procedural formality. 

Did you know? 
Setting up a company as a separate legal entity provides a layer of protection for the individuals behind it. Owners, known as shareholders, and directors—who manage the business and in the case of most small businesses, shareholders and directors are the same person — gain a degree of financial and legal protection. In instances where the company faces legal action or incurs debt, the personal assets of shareholders and directors are generally protected, provided there is no fraudulent activity or breach of director duties. This setup shields personal wealth from business liabilities, offering a safeguard that is especially valuable in the unpredictable world of business. 

Transitioning from sole trader to company is my ABN transferable? 

As your business grows, you might consider moving from being a sole trader to establishing a company.  It is however important to understand when to transition and what it entails. 

One common query in this process is about whether your ABN is transferable when you change from sole trader to company.  The short answer is no due to each ABN being specific to the business entity’s legal structure it's associated with.
