When starting a business in Australia, understanding the difference between trading names, legal entity names, and registered business names is essential for compliance.
Many new business owners confuse these terms, leading to incorrect registrations and potential legal issues.
This guide explains each concept clearly and walks you through the registration process for each.
Key Definitions: What Is Each Type of Name?
Before discussing registration, let's define each term precisely under Australian law.[citation:5]
Legal Entity Name
Your legal entity name is the official name that appears on all legal documents, contracts, and official registrations.
It is determined by your business structure:
- Sole Trader: Your legal name is your personal name (e.g., 'John Michael Smith').
- Partnership: The legal name is the names of all partners (e.g., 'John Smith and Mary Jones').
- Company: The legal name is the registered company name, which must end with 'Pty Ltd' (e.g., 'Smith Retail Pty Ltd'). This name is registered with ASIC when you incorporate.
- Incorporated Association: The legal name is the name registered with the relevant state authority.
Registration required? For sole traders and partnerships, no registration is needed—your legal name is simply your personal name.
For companies, yes—the company name is registered with ASIC as part of the incorporation process.
Trading Name (Historical Concept - No Longer Registerable)
A trading name is an unregistered name that businesses could use before the introduction of the national Business Names Register on 28 May 2012.[citation:5]
- Before 2012, businesses could operate under multiple 'trading names' without registering them separately.
- Trading names still appear on ABN Lookup for historical reference, but you cannot register a new trading name today.
- If you want to use an old trading name that is still listed, you must now register it as a formal business name.
Important: Do not try to 'register a trading name'—this is no longer possible. What you need is a registered business name.
Registered Business Name
A registered business name is the name you register with ASIC to conduct business under a name other than your legal entity name.[citation:5]
- You can have multiple business names linked to your ABN.
- Once registered, the name is protected nationally (no other business can register the same name).
- Registration must be renewed every 1 or 3 years.
Examples: John Smith (sole trader) registers 'Smith's Homewares' as a business name. 'John Smith' is his legal name; 'Smith's Homewares' is his registered business name.
When Do You Need to Register Each Type of Name?
Understanding when registration is required will save you from unnecessary work and fees.[citation:1]
- Legal Name - Sole Trader: No registration needed. Use your personal name freely.
- Legal Name - Partnership: No registration needed if using all partners' full names. However, you may want a partnership agreement.
- Legal Name - Company: Registration is mandatory when you incorporate with ASIC. The company name is your legal name.
- Trading Name (historical): Cannot register. Convert to a business name instead.
- Business Name: Registration is required if you trade under any name other than your legal entity name.
Key Rule: If your customers see a name that is not your legal name, you need to register that name as a business name with ASIC.
Step-by-Step: How to Register a Business Name (Not a 'Trading Name')
Since 'trading names' are obsolete, follow these steps to register a business name instead.[citation:3]
Step 1: Obtain an ABN
You cannot register a business name without an Australian Business Number (ABN). If you don't have one, apply through the Australian Business Register first.
ABN applications are free and can be completed online.
Step 2: Choose Your Business Structure
Decide whether you are registering as a sole trader, partnership, or company. Your ASIC application will require this information.
Step 3: Check Name Availability
Search ASIC's business names register to ensure your desired name is not already taken.
If the name is identical or 'nearly identical' to an existing registration, you cannot register it.
Step 4: Apply Online Through ASIC Connect
The application takes about 10-15 minutes. You will need your ABN, chosen business structure, personal or company details, and registered address in Australia.
Step 5: Pay the Registration Fee
Choose a registration period:[citation:3]
- $45 for 1 year
- $104 for 3 years
Credit card payment gives faster confirmation (2 business days) compared to BPAY or bank transfer (5 business days).
Step 6: Receive Confirmation
Once approved, you will receive a certificate of registration. Your business name now appears on the national register.
Step-by-Step: How to Register a Company Name (Legal Entity Name)
If you are forming a company (Pty Ltd), the company name registration is part of the incorporation process with ASIC.[citation:6]
Step 1: Choose a Company Name
Your company name must end with 'Proprietary Limited' or 'Pty Ltd.' Check that the name is available—not already registered with ASIC.
Step 2: Prepare Company Details
You will need:
- Proposed company name
- Registered office address (physical address in Australia, not a PO Box)
- Details of directors and company secretary (at least one director must ordinarily reside in Australia)
- Details of shareholders
- Company constitution (or agreement to adopt replaceable rules under the Corporations Act)
Step 3: Apply for Registration Online
Use the ASIC Connect portal to submit your application. You will receive an Australian Company Number (ACN) upon registration.
This ACN becomes part of your legal identity.
Step 4: Receive Certificate of Registration
Once approved (typically 1-3 business days for straightforward applications), you receive a certificate of registration.
Your company now exists as a separate legal entity.
Step 5: Apply for ABN and TFN
After incorporation, apply for an ABN and Tax File Number for your new company through the Australian Business Register.
Can a Legal Entity Name Be Different from a Business Name?
Yes, and this is very common. Many businesses operate under a brand name that differs from their legal entity name.[citation:5]
- Legal Entity Name: 'Smith Retail Holdings Pty Ltd' (registered company name)
- Registered Business Name: 'Smith's Homewares' (registered with ASIC as a business name)
- Result: The company trades as 'Smith's Homewares' but its legal name is 'Smith Retail Holdings Pty Ltd.'
Conversely, a company can choose to trade under its registered company name without registering a separate business name.
In that case, the legal name and trading name are identical.
Do You Need Both a Company Name and a Business Name?
Not necessarily. Here is when each is required:
- Trading under your registered company name: No separate business name registration needed. Your company name is your trading name.
- Trading under a name different from your registered company name: You must register that different name as a business name with ASIC (even though you already have a company name).
- Sole trader trading under personal name: No registration needed.
- Sole trader trading under a brand name: You must register a business name.
The short answer is that 'trading names' no longer exist as a registrable concept.
Register a business name instead, and understand whether your legal name already allows you to trade without additional registration.
