Register a Business Name in Australia: The Complete 2026 Guide
Choosing and registering a business name is one of the first legal steps most new businesses in Australia need to take. Get it right and you trade with confidence, protect your brand identity, and avoid delays that can hold up contracts, banking, and marketing. Get it wrong, and you could face a rejected application, a dispute with another business, or a name you cannot actually use the way you planned.
This guide walks through exactly how to register a business name in Australia in 2026: who needs to register one, the step by step process through the Australian Securities and Investments Commission (ASIC), what it costs, how long it takes, and the mistakes that trip up new business owners most often. If your situation involves a company structure, multiple founders, or overseas ownership, it also explains when it makes sense to bring in a lawyer rather than go it alone.
What Is a Business Name in Australia
A business name, sometimes called a trading name, is the name you use to operate and market your business when that name is different from your own legal name. Your legal name is either your personal name as a sole trader, or the registered legal entity name of your company, partnership, or trust.
For example, if you operate as a sole trader and your legal name is John Carter, you can trade as "John Carter" without registering anything extra. The moment you want to trade as "Carter Building Co" instead, that becomes a business name, and it must be registered separately with ASIC before you use it publicly, put it on invoices, or open a business bank account under that name.
A registered business name is not the same thing as a company. A company is a separate legal entity created through ASIC under the Corporations Act, with its own ACN (Australian Company Number). A business name is simply a trading identity, and it can sit on top of a sole trader, a partnership, a trust, or a company. If you are weighing up whether to trade as a sole trader or set up a company first, it is worth reading our guide on how to establish a company in Australia before you lock in a trading name, since the structure you choose can affect how the name is held and who is listed as the business name holder.
Do You Need to Register a Business Name
You need to register a business name with ASIC if any of the following apply:
- You are a sole trader and want to trade under a name other than your own full legal name.
- You are in a partnership and want to trade under a name other than the full legal names of all partners.
- You have registered a company and want to trade under a name that is different from the company's registered legal name.
- You are operating through a trust and the trust wants to trade under a name other than the trustee's legal name.
You generally do not need to register a business name if:
- You are a sole trader trading under your own exact personal name, with no added words (for example "Jane Smith" rather than "Jane Smith Photography").
- Your company trades under its exact registered company name, including the "Pty Ltd" suffix where applicable. If you are unsure what that suffix actually means for your structure, our explainer on what does Pty Ltd mean breaks it down in plain language.
The test ASIC applies is simple: if the public-facing name differs in any way from the legal name behind it, even by adding a single descriptive word, that name needs to be registered as a business name before you start using it.
Business Name, Company Name, and Trading Name: Clearing Up the Confusion
These three terms get mixed up constantly, so it is worth being precise:
- Legal entity name is the name on your formal registration, whether that is your own name as a sole trader, your partnership agreement, your trust deed, or your company's certificate of registration.
- Company name is the legal entity name of a company specifically, registered under the Corporations Act and almost always ending in "Pty Ltd" or "Ltd".
- Business name (also called a trading name) is any name used publicly that differs from the legal entity name, and it must be separately registered with ASIC regardless of what structure sits behind it.
A single company can register several business names if it operates multiple brands under one legal entity, which is common for businesses running different product lines or regional brands from the same corporate structure.
Before You Register: What to Prepare First
A smooth registration starts well before you open the ASIC application form. Work through these steps first.
1. Decide on your business structure
Your business name sits on top of a legal structure, so decide whether you are operating as a sole trader, partnership, trust, or company before you register. If you are leaning toward a company structure, read through our guide on how to set up a Pty Ltd company in Australia so the business name and the company registration can be lodged in the right order.
2. Get your Australian Business Number (ABN)
ASIC links every business name registration to an ABN held by the same holder. In practice this means you need an ABN already active, or you apply for the ABN and the business name together through the Australian Government Business Registration Service. ABN applications through the Australian Business Register are free.
3. Brainstorm and shortlist names
Pick a shortlist of two or three names rather than falling in love with one option. Keep these practical points in mind:
- Avoid names that are offensive, misleading about the business's activities, or suggest a government or regulatory connection you do not have.
- Check that a matching domain name and social media handles are realistically available.
- Think about how the name reads and sounds, since a name that is hard to spell can cost you search traffic and word-of-mouth referrals later.
4. Check name availability on the ASIC register
Search the ASIC business names register and the ASIC company register before you apply. ASIC will not register a name that is identical or nearly identical to an existing registered business name or company name, so this check saves you a wasted application fee. We have put together a dedicated walkthrough of this step in our guide to checking business name availability in Australia, including how ASIC's "near identical" rule actually works in practice.
5. Check for trademark conflicts
A name clearing the ASIC register does not mean it is free to use. ASIC only checks for identical or near identical names on its own register, it does not check the trademark register held by IP Australia. If you register a business name that infringes an existing registered trademark, the trademark owner can still take action against you, and you could be forced to rebrand after you have already spent money on signage, packaging, and marketing. Searching the IP Australia trademark database, and speaking with a lawyer about trademark protection for your own name, are both worth doing at this stage rather than after a dispute arises.
Step by Step: How to Register a Business Name With ASIC
Once your preparation is done, the registration itself is a relatively fast online process. Here is how it works in 2026.
Step 1: Set up your access to lodge
You can apply online in one of two main ways. If you already hold an ABN, you can apply directly through ASIC Connect. If you are applying for an ABN and a business name at the same time, you can do both through the Australian Government Business Registration Service, which feeds your business name application through to ASIC once your ABN is confirmed.
Step 2: Enter your proposed business name
Type in your chosen name and run it through the system's availability check. The result will typically come back as either available, or flagged for manual review if it looks similar to an existing registered name. If it is flagged, you may need to choose a different name or provide further information before ASIC will approve it.
Step 3: Enter the business name holder's details
The "holder" is the legal entity that will own the business name: you as an individual, your company via its ACN, your partnership, or your trust. You will need to provide the holder's ABN, registered address details, and contact information. Make sure these details exactly match what is held by the Australian Business Register, since mismatches are a common cause of application delays.
Step 4: Choose your registration period
You can register a business name for one year or three years. A three year registration costs more upfront but saves you the administrative task of renewing annually, and it reduces the risk of accidentally letting the registration lapse.
Step 5: Review and submit your application
Double check the spelling, spacing, and punctuation of the business name exactly as you want it to appear, since this is what will be published on the public register. Review the holder details one more time, then submit.
Step 6: Pay the registration fee
Payment is made online as part of the application. You can typically choose to pay immediately or select a "pay later" option, though your registration will not be finalised until payment clears.
Step 7: Receive confirmation
Once approved, ASIC issues a registration record, often called a business name extract, confirming the name, the holder, the ABN it is linked to, and the registration period. Your business name also becomes visible on the public ASIC register at this point, which is often needed to open a business bank account, set up a merchant facility, or finalise supplier contracts.
How Much Does It Cost to Register a Business Name in Australia
ASIC charges a government fee for business name registration, with two options:
- A one year registration, which is the lower upfront cost but needs renewing annually.
- A three year registration, which costs more upfront but covers a longer period without needing to renew.
ASIC reviews these fees periodically, so always confirm the current published amount on the ASIC website before you apply, rather than relying on a figure from an older article. If you engage a registered agent, accountant, or lawyer to handle the application for you, there will usually be a separate professional fee on top of the ASIC government fee, which reflects the time spent on name checks, trademark screening, and structuring advice rather than the registration itself.
How Long Does Business Name Registration Take
Straightforward applications, where the name is clearly available and the ABN details check out instantly, are often processed quickly, sometimes within the same day. Applications that get flagged for manual review, because the proposed name is similar to an existing registration, or because the ABN details could not be automatically verified, can take noticeably longer while ASIC staff assess the application by hand. Building in a buffer of several business days before you need the registration finalised, for example before a bank appointment or a contract signing, is a sensible precaution.
Common Mistakes to Avoid When Registering a Business Name
Most problems that come up during business name registration are avoidable with a bit of planning. The most frequent ones we see are:
- Trading before registration is confirmed. Putting a new name on invoices, signage, or a website before ASIC has actually approved it can create a gap where you are technically trading under an unregistered name.
- Assuming registration equals trademark protection. As covered above, registering a business name only blocks identical or near identical names on the ASIC register. It does not stop a competitor from trademarking the name and later asking you to stop using it.
- Mismatched holder details. If the ABN holder details do not match exactly what you enter in the business name application, the system can reject or delay the application.
- Choosing a name that misleads about your business. Names that imply a government connection, a professional qualification you do not hold, or an activity you are not licensed for can be rejected or cause compliance issues later.
- Forgetting to renew. If a business name registration lapses, someone else can register it, and you would then have to apply for a brand new registration, assuming the name is still available at all.
- Registering a name that is not actually used consistently. If your website, invoices, and marketing material use variations of the registered name, this can create confusion with customers and, in some cases, compliance questions down the line.
Renewing, Updating, and Cancelling a Business Name
A business name registration is not a one-off task. A few ongoing obligations sit alongside it:
Renewing your business name
ASIC will issue a renewal notice ahead of your registration's expiry date. You can renew through ASIC Connect or ASIC's online payment service, and the renewal fee mirrors the original registration fee for the period you choose.
Updating your details
If your business address, contact details, or ownership structure changes, you are required to update your business name record in ASIC Connect. Keeping these details current matters because an outdated address can mean you miss a renewal notice entirely.
Changing to a new business name
You cannot simply edit a registered business name. If you want to trade under something different, you need to register the new name first and then cancel the old registration through ASIC Connect, rather than cancelling the old one first and risking a gap where you have no valid registered name at all.
Cancelling a business name
If you close the business, change structure, or no longer need the trading name, you can cancel it through ASIC Connect. Once cancelled, the name becomes available for someone else to register.
Business Name Registration vs Trademark Protection
This is one of the most misunderstood areas of Australian business law, so it is worth repeating clearly: registering a business name with ASIC and registering a trademark with IP Australia are two completely separate systems that serve different purposes.
Business name registration is primarily about transparency and disclosure. It tells the public who is actually behind a trading name, and it stops another business from registering an identical or near identical name on the same register. It does not give you ownership of the words themselves, and it does not stop a competitor in a different industry, or even the same industry, from using a similar name if they are not on the ASIC register with an identical match.
A trademark, by contrast, gives you exclusive legal rights to use a specific name, logo, or slogan in connection with particular goods or services, enforceable nationally once granted. If your brand name is central to your business value, for example in retail, hospitality, or consumer products, registering both your business name with ASIC and a trademark with IP Australia gives you much stronger protection than relying on the business name registration alone. For businesses thinking seriously about brand protection, it is worth reading our broader guide on intellectual property law in Australia to understand how trademark, copyright, and business name registration fit together.
Registering a Business Name as an Overseas Entity
Foreign individuals and overseas companies establishing operations in Australia can also register a business name, but there are extra steps involved. You generally need to register a presence in Australia first, whether that is as a foreign company registered with ASIC or through an Australian subsidiary, and you will need an Australian registered agent and office address. If you are setting up in Australia from overseas, our guide on investment and market entry into Australia covers the broader structuring questions that usually need to be answered before the business name registration itself, including entity choice, FIRB considerations where relevant, and local compliance obligations.
What Happens After Registration
Once your business name is registered, a few practical next steps typically follow:
- Open a business bank account under the registered name.
- Update your invoicing, website, and contracts to reflect the registered name exactly as it appears on the ASIC register.
- Check whether your business needs to register for GST. Our guide to GST registration in Australia explains the turnover thresholds and timing requirements.
- Set up your record keeping and tax obligations correctly from the start, which our overview of income tax and auditing in Australia can help you plan for.
- Consider whether a trademark application makes sense to protect the name beyond what ASIC registration covers.
Frequently Asked Questions
Do I need to register a business name if I am a sole trader?
Only if you trade under a name different from your own legal name. Trading under your exact personal name does not require a separate business name registration.
How much does it cost to register a business name in Australia?
ASIC charges a government fee that differs for a one year registration versus a three year registration. Fees are reviewed periodically, so confirm the current amount directly on the ASIC website before applying.
Does registering a business name protect it like a trademark?
No. ASIC registration only prevents identical or near identical names from being registered on the same register. It does not grant exclusive rights to the name and does not replace trademark protection through IP Australia.
Do I need an ABN before I register a business name?
Generally yes, since every business name must be linked to an ABN held by the same entity. You can apply for an ABN and a business name together through the Australian Government Business Registration Service if you do not already have one.
How long does it take to register a business name with ASIC?
Straightforward applications are often processed quickly, while applications flagged for manual review because the name resembles an existing registration can take longer.
Can I change my business name later?
You cannot edit a registered name directly. You need to register the new name first, then cancel the old registration through ASIC Connect.
What is the difference between a business name and a company name?
A company name is the legal entity name registered under the Corporations Act, usually ending in Pty Ltd. A business name is a separate trading name registered on top of a legal entity, whether that entity is a sole trader, partnership, trust, or company.
Getting Legal Help With Business Name Registration
Most straightforward business name registrations can be completed without a lawyer. Where legal advice genuinely pays for itself is in situations involving multiple founders and ownership structures, overseas entities entering the Australian market, names that sit close to an existing trademark, or businesses planning a company structure and a business name registration at the same time and wanting them set up correctly from day one.
Collins Quarters Legal advises founders, sole traders, and companies across corporate and commercial law matters, including entity structuring, business name and trademark strategy, and broader startup compliance. If you want a clear structuring plan before you register, or you are unsure whether a name you like might run into trademark trouble later, you can book a consultation or get in touch with our team to talk through your options before you lodge anything with ASIC.
Key Takeaways
- You need to register a business name with ASIC whenever you trade under a name different from your own legal name or your company's registered name.
- An ABN is required before, or alongside, your business name application.
- Checking the ASIC register and the IP Australia trademark database before you apply saves you time, money, and the risk of a forced rebrand later.
