If you’re starting a business in Australia, one of the first admin tasks you’ll come across is getting an Australian Business Number (ABN). In many cases, it’s a genuine “first step” because it links into invoicing, GST registration, business banking, supplier accounts, and how you present yourself to customers.
But there’s an important catch: not everyone is entitled to an ABN.
From a small business owner’s perspective, this matters for two reasons. First, you don’t want your application rejected (or worse, cancelled later). Second, you don’t want to set up a business model that accidentally looks like an employment arrangement or a hobby - because that can create tax, compliance and dispute risks later on.
This guide walks you through who can generally apply for an ABN, who typically can’t, and how to sanity-check your position before you apply.
Note: This article is general information only and isn’t tax advice. ABN, GST and withholding rules can be fact-specific and change over time. For guidance on your tax position, check the ATO/ABR guidance or speak with a qualified accountant or tax adviser.
What Does It Mean To Be Entitled To An ABN?
An ABN is a unique 11-digit identifier issued by the Australian Business Register (ABR). It’s used to identify your business (or other entity) when dealing with other businesses, government agencies, and the tax system.
In plain terms, ABN entitlement usually comes down to this question:
Are you carrying on an “enterprise” in Australia (or making supplies connected with Australia) as the entity applying for the ABN?
In practice, the ABR and the ATO look for whether you’re genuinely operating like a business (or another eligible type of enterprise), rather than:
- an employee,
- a hobbyist, or
- someone applying “just in case” without any real business activity.
That’s why entitlement isn’t just about your intention to start. It’s also about your structure, your activities, and whether what you’re doing has the hallmarks of an ongoing enterprise.
If you’re unsure whether your planned activity even counts as a business-like enterprise, it helps to start with the idea of business activity and how it’s generally understood in Australia.
Who Is Entitled To An ABN?
Most small businesses and startups are entitled to an ABN - but only if they’re applying as an eligible entity and they’re carrying on (or genuinely starting) an enterprise.
Below are common categories of applicants who are generally entitled to an ABN when the circumstances fit.
Sole Traders (Individuals) Running A Business
If you’re operating as a sole trader (you personally run the business, and you personally earn the income), you’re commonly entitled to an ABN where you are carrying on an enterprise.
Typical examples include:
- consultants and freelancers providing services to clients
- eCommerce store owners selling products online
- tradies quoting and performing jobs under their own business name
- agency-style service businesses (marketing, design, development, coaching)
From a business owner’s point of view, an ABN can be important because it affects how you invoice and how clients treat your invoices for tax purposes. It can also tie into whether no ABN withholding is applied to payments in some situations (which is a tax/ATO issue you should confirm with the ATO or an accountant for your circumstances).
Companies
If you’re operating through a company (a separate legal entity), the company itself can be entitled to an ABN, provided it is carrying on an enterprise.
This is common for startups planning to scale, bring in investors, hire staff, or separate personal assets from business liabilities. It also tends to suit higher-risk industries and businesses with multiple founders.
Practically, a company will often put a Company Constitution in place (or adopt replaceable rules) as part of being properly set up for growth and governance.
Partnerships
A partnership (where two or more people carry on a business together with a view to profit) can also be entitled to an ABN.
It’s worth noting that partnerships can be simple to start, but they can become complicated if expectations aren’t documented early. If you’re going into business with someone else, a Partnership Agreement is often the difference between a smooth working relationship and a stressful dispute later.
Trusts
Many small businesses operate through a trust structure (for example, for asset protection or tax planning reasons), and a trust may be entitled to an ABN where the trustee is carrying on the enterprise on behalf of the trust.
Trust structures are common, but they’re also an area where getting the setup right early matters - because the ABN application and ongoing compliance depends on the entity that is actually conducting the enterprise (for example, the trustee).
Not-For-Profits And Other Organisations
Some non-profit organisations are also entitled to an ABN where they are carrying on an enterprise (even if their purpose is not profit). For example, certain incorporated associations and charities may be eligible depending on their activities and registration status.
If your startup has a community or membership model, it’s important to be clear about whether you’re truly operating as a not-for-profit, a social enterprise, or a standard commercial business - because that can affect ABN eligibility, as well as reporting and tax obligations.
Who Is Not Eligible For An ABN (Common Scenarios)
This is where many people get caught out - especially early-stage founders who are still exploring an idea, or businesses that engage contractors in a way that can look like employment.
Here are common situations where an ABN may be refused, cancelled, or create compliance issues.
Employees (Or Arrangements That Look Like Employment)
If someone is working as an employee, they generally won’t need (and shouldn’t be asked to use) an ABN “instead of” employment payroll arrangements. From a business owner perspective, this can be a risk area because it may indicate misclassification and potential sham contracting issues.
Even if the worker has an ABN, that doesn’t automatically make them a contractor.
Red flags that an arrangement looks like employment include:
- you control how, when and where they work (like you would an employee)
- they wear your uniform and are presented as part of your staff
- they don’t have their own clients and work mainly (or only) for you
- they don’t invoice in a business-like way, or don’t bear commercial risk
If you engage contractors in your business, it’s worth understanding the practical and legal realities of working under an ABN, so your contractor model stays defensible and clear.
Hobbies Or One-Off Activities Without A Business-Like Purpose
If someone is doing something purely as a hobby (for enjoyment, without a clear business intention or commercial structure), they may not be entitled to an ABN.
For small business owners, this usually comes up when you’re “testing” an idea: selling a few items casually, taking occasional paid gigs, or experimenting with a side project. Testing is fine - but if there’s no real enterprise activity yet, the ABR may not treat it as eligible on the facts.
A common mistake is applying for an ABN too early without any genuine steps towards carrying on a business.
People Applying “Just In Case” (No Enterprise Commenced Or Seriously Planned)
If there’s no evidence you are starting or carrying on an enterprise, ABN entitlement can be questioned.
In a practical sense, you’re on stronger footing if you can point to business-like steps, such as:
- a defined offering (what you sell, who you sell to, and how)
- set pricing or a quoting process
- a website, social accounts, or marketing activity
- supplier relationships or a service delivery plan
- invoicing and record-keeping systems
Businesses Using The Wrong Entity
Another practical issue we see is where a business applies for an ABN under the wrong “owner” (for example, an individual applies personally, but all operations are actually intended to run through a company, partnership, or trustee structure).
This can create confusion about:
- who is contracting with customers and suppliers
- who owns the IP and brand assets
- who is responsible for debts and liabilities
- how income should be recorded and taxed
If you’re building a startup with co-founders or planning to raise capital, sorting out the entity and ownership early is often just as important as the ABN itself.
How To Work Out If You Should Apply (A Practical Checklist)
If you’re trying to work out whether you’re likely to be eligible for an ABN in a real-world, small business scenario, it helps to run through a business-focused checklist.
You don’t need to tick every box perfectly, but the more “yes” answers you have, the more you look like you are carrying on an enterprise.
1. Are You Operating With A Genuine Commercial Purpose?
- Are you aiming to make a profit (even if you’re not profitable yet)?
- Do you have pricing, quotes, packages, or product listings?
- Are you taking steps to generate ongoing sales, not just a once-off?
2. Do You Have Evidence Of Business-Like Activity?
- Do you have a business plan or launch plan?
- Have you set up a website, landing page, or online store?
- Are you advertising, networking, or actively seeking clients?
- Have you set up business systems (bookkeeping, invoicing, customer management)?
3. Are You Exposed To Commercial Risk?
- Do you pay for tools, software, subscriptions, stock, or advertising?
- Could you make a loss if things don’t go to plan?
- Do you have responsibilities to customers (like delivery timelines or service standards)?
4. Are You In Control Of How You Deliver Your Product Or Service?
This is particularly important if your business model involves contractors or freelance work.
- Do you decide how you do the work, rather than being managed like staff?
- Do you have the ability to take on other clients?
- Do you invoice clients and manage your own tax obligations?
5. Are You Choosing The Right “Applicant” Entity?
- Is the ABN going to be held by the same entity that signs customer contracts and invoices?
- If you have co-founders, have you decided whether you’re operating as a partnership or a company?
- If you’re using a trust, is the trustee applying in the correct capacity?
Once you’re set up, it’s also worth doing basic checks as part of your onboarding and supplier processes. For example, many businesses routinely confirm counterparties’ ABNs - and knowing how to check if an ABN is active can help reduce invoicing and payment risk.
What To Set Up Alongside Your ABN (So Your Business Looks And Operates Like A Business)
An ABN is often just one piece of the puzzle. If you want to avoid disputes and compliance headaches later, it helps to treat the ABN as part of a broader “business foundation” you build early - especially if you’re planning to scale.
Choose A Structure That Matches Your Risk And Growth Plans
ABNs can be issued to different entity types, so the question isn’t only “am I eligible?” - it’s also “which entity should hold the ABN?”
- Sole trader: simple and low-cost, but you carry the liabilities personally.
- Company: a separate legal entity, often better for growth and risk management.
- Partnership: workable for some co-founders, but it’s important to document roles and decision-making.
- Trust: can be suitable in some circumstances, but needs careful setup.
If you’re still deciding whether you even need an ABN at all (or whether you can start before getting one), it’s worth thinking through the practical realities of run a business without an ABN and what that means for invoicing, credibility, and tax administration.
Understand Your Tax Touchpoints (Especially GST And Invoicing)
For many businesses, the ABN is tied into day-to-day commercial operations:
- issuing tax invoices and receiving payments
- GST registration (where required)
- withholding rules and supplier onboarding
- business name and branding consistency on invoices and proposals
It’s also a good idea to understand the broader pros and cons, particularly if you’re deciding whether to operate as a side business or formalise quickly. The advantages and disadvantages of having an ABN can help you weigh up what “formalising” means for compliance and admin (and for anything tax-specific, check the ATO guidance or get advice).
Put The Right Contracts In Place Early
One of the biggest risks we see in early-stage businesses is that founders focus on registering identifiers (like an ABN) but forget the documents that actually control the commercial relationship.
Depending on how your business operates, consider whether you need:
- Customer terms (so your payment terms, scope and limitations are clear)
- Supplier terms (so supply, delivery, and quality expectations are documented)
- Contractor agreements (so your team isn’t accidentally treated like employees)
- Founder and ownership documents (so decision-making and equity are clear)
If you’re hiring employees rather than contractors, a clear Employment Contract helps set expectations and reduce disputes as you grow.
Don’t Forget Privacy If You’re Collecting Customer Data
Many startups collect personal information quickly - even before launch - through waitlists, email signups, contact forms, or payment platforms.
If you’re collecting personal information, a Privacy Policy is one of the most practical ways to explain what data you collect, how you use it, and how customers can contact you about it.
This is particularly relevant for online businesses, SaaS products, marketplaces, and any business that relies on marketing automation or customer analytics.
Key Takeaways
- Whether you’re entitled to an ABN generally comes down to whether the applying entity is carrying on an enterprise in Australia (or genuinely taking steps to start one).
- Sole traders, companies, partnerships and trusts can all be eligible for an ABN, as long as the ABN is held by the entity that is actually running the business activity.
- Common scenarios where an ABN may not be appropriate include employment-style arrangements, hobby activities, and applicants with no real enterprise activity underway.
- Before applying, check whether your activity looks commercial: a clear offering, real plans, marketing, customers (or steps toward customers), and business-like systems all help.
- An ABN is only one part of a strong setup - your structure, contracts, hiring arrangements, and privacy compliance are just as important for protecting your business long-term.
