Picking a name for your business is the fun part. Registering it is where people slow down, second-guess themselves, and sometimes get it wrong.
The good news is that business name registration in Australia is genuinely straightforward. The whole thing can be done online in under an hour. The not-so-good news is that there are a few things worth understanding before you start, because some of the common assumptions people carry into this process are just wrong.
This guide covers how it works, what the rules are, and what trips people up when doing company registration in Australia.
First, Do You Even Need to Register a Business Name?
Not everyone does. A lot of people register a business name out of habit without checking whether they actually need to. Here is the rule.
You need to register a business name if you are trading under any name that is not your own full legal name.
That means:
- John Smith trading as John Smith does not need to register anything
- John Smith trading as “Smith Electrical” or “North Shore Repairs” absolutely does
- A company registered as “Fletcher Holdings Pty Ltd” trading as “Fletcher Holdings Pty Ltd” does not need a separate business name
- That same company trading publicly as “FlexBuild” does need to register that as a separate business name
Simple rule. If the name on your invoices, website, or signage is different from your legal personal name or your exact registered company name, it needs to be registered with ASIC.
One update worth knowing as of November 2025. Unregistered trading names were removed from public visibility on the Australian Business Register. If your business was relying on an informal trading name that was never formally registered, it no longer shows up in public searches. If that applies to you, register it now.
What Business Name Registration Actually Does
People often assume that registering a business name protects it. It does, but only in a limited way.
Here is what registration with ASIC actually gives you:
- The right to legally trade under that name in Australia
- A public record confirming your business identity
- Protection from another business registering the identical name with ASIC
Here is what it does not give you:
- Trademark protection
- Any legal right to stop a sole trader from using a similar name
- Any protection for your brand, logo, or identity
If the name you are building a business around genuinely matters to you, register it as a trademark through IP Australia separately. Business name registration and trademark registration are two different things handled by two different government bodies. One gets you on the register. The other gives you actual brand protection.
Step 1: Get an ABN First
You cannot register a business name without an Australian Business Number. It is a prerequisite, not a parallel step.
If you do not have one yet, apply through the Australian Business Register online. It is free. Most applications are processed immediately. The ABN is an 11-digit number that identifies your business across all government interactions, tax filings, and commercial dealings.
Once you have your ABN, you are ready to register the name.
Step 2: Check Whether Your Name Is Available
Do this before you fall in love with a name. Two checks, both important.
Check the ASIC register
Use the business name availability search on ASIC Connect. The name you want cannot be identical to one already registered. It also cannot be so similar to an existing name that it would confuse people.
Check the IP Australia trademark database
A name can be fully available on the ASIC register and still belong to someone else as a registered trademark. Registering a name with ASIC does not override an existing trademark. If you build a brand on top of someone else’s trademark, you will eventually receive a letter from their lawyer.
Ten minutes of checking both databases saves enormous headaches later.
The Naming Rules Worth Knowing
ASIC has clear rules about what names are acceptable. Most of them are straightforward. A few catch people off guard.
Names that are not allowed:
- Identical or confusingly similar to an existing registered business or company name
- Offensive or obscene in any way
- Misleading about the nature or location of the business
- Names that imply a connection to a government body, the Royal Family, or a registered charity without authorisation
Restricted words that need special approval:
Words like “bank,” “trust,” “finance,” “insurance,” “university,” “registered,” “incorporated,” and similar terms require written approval from the relevant authority before you can use them. Using them without approval gets your application rejected.
Practical rules:
- Names can only use letters of the English alphabet, numbers, spaces, and common punctuation marks
- The name cannot be a single letter or number on its own
- Names must not be over a reasonable length or deliberately formatted to confuse
Step 3: Register Through ASIC Connect
The registration itself is done through ASIC Connect, the online portal. You can also use the Australian Government’s Business Registration Service, which is worth knowing because it lets you apply for your ABN, register your business name, and set up GST all in one form if you are starting fresh.
What you need to have ready:
- Your ABN
- The business name you want to register
- Your contact details and address
- Payment method
The fees as of July 2025:
- One year: $42
- Three years: $98
The three-year option almost always makes more sense. You save money and avoid the administrative task of renewing annually.
Most online applications are processed almost instantly once payment is received. You will get a Record of Registration emailed to you confirming the name is yours.
Step 4: Display Your Business Name Correctly
Once registered, there are rules about how you use the name. These are not optional.
You must display your registered business name on:
- All invoices and receipts
- Business signage
- Any written contracts with clients or suppliers
- Your website and marketing materials
- Correspondence with government bodies
You also need to display your ABN alongside the business name in most commercial contexts. Leaving either off invoices is a common oversight that creates problems with clients who need to verify your details for their own records.
Step 5: Renew Before It Expires
Business name registration is not permanent. It expires at the end of the period you paid for, one year or three years.
ASIC sends renewal notices before expiry, but the responsibility to renew is yours. If you let it lapse, the name becomes available for anyone else to register. And if someone else picks it up while you are still trading under it, you have a problem.
Renew through ASIC Connect using your account number or ABN. The fee is the same as the initial registration. Set a calendar reminder well before the expiry date. It takes five minutes to renew and significantly more time to untangle if it lapses.
What Business Name Registration Does Not Cover
Worth being clear on this because it catches people regularly.
It is not the same as company registration. A business name is a trading name. A registered company is a separate legal entity with its own ACN and limited liability protection. If you want the protection that comes with a Pty Ltd structure, you need to go through ASIC’s company registration process separately.
It does not protect your brand. Someone can operate as a sole trader using a name very similar to yours and business name registration gives you no legal recourse against them. Only a registered trademark gives you that.
It does not cover a domain name or social media handles. Register those separately and do it early. A business name registration does not secure your .com.au domain or your Instagram handle. Someone else can take them while you are sorting out the paperwork.
One Thing That Changed in 2025
As mentioned earlier, as of November 2025, unregistered trading names were removed from the Australian Business Register. If your business had been showing up under an informal name that was never properly registered, that visibility is gone.
This matters for two reasons. Clients searching for your business by that name through ABN Lookup or the ABR will no longer find it. And it is a reminder that informal arrangements do not hold up over time. Register what you are trading under. It is $42 and twenty minutes of your time.
Getting Your Business Name Right From the Start
Business name registration is one of the first steps in company registration in Australia and it is genuinely simple when you approach it in the right order. Get the ABN first, run both name checks, register through ASIC Connect, and set a renewal reminder.
The mistakes are always avoidable. Skipping the trademark search, letting the registration lapse, assuming the name is protected when it is not. None of these are complicated to get right. They just need to be thought about before they become a problem.

FAQs
1. Do I need a business name if I trade under my own name?
No. If you operate using your full legal first and last name and nothing else, registration is not required. Add anything to your name, even “and Co,” and you need to register it.
2. How long does business name registration take?
Most online applications through ASIC Connect are processed almost instantly after payment. You will receive your Record of Registration by email within minutes in most cases.
3. Can two businesses have the same name in Australia?
No. ASIC will not register a name that is identical to one already on the register. Similar names may be allowed depending on how closely they resemble existing registrations, but identical names are rejected outright.
4. Does registering a business name protect it as a trademark?
No. These are entirely separate things. ASIC registration stops someone from registering the same business name. A trademark registered through IP Australia gives you actual legal protection over your brand identity.
5. What happens if I do not renew my business name?
It expires and becomes available for anyone else to register. ASIC sends renewal notices but the responsibility to act on them is yours. If the name matters to your business, set a reminder well before the expiry date.
