How to Register a Business Name in Australia: A Guide for Tradies & Service Businesses

If you're starting a trade or service business in Australia, one of the first decisions you'll need to make is what your customers will know your business as.

You might operate as a sole trader under your own name, or you might want to trade under a name such as Smith Lawn Care, Brisbane Pool Services or Jack's Property Maintenance.

If you want to trade under a name that's different from your legal name, you'll generally need to register it as a business name. This guide explains when registration is required, how to choose and check a name, what it costs and how to register it.

Before you start, you'll need an Australian Business Number (ABN), or an ABN application reference number, to register a business name. If you haven't applied yet, our guide to getting an ABN in Australia explains the process.

What is a business name and do you need one?

A business name is the name your business trades under and presents to customers. It isn't necessarily the same as the legal name of the person or entity operating the business.

For example, imagine you're a sole trader named Jack Williams. You could simply operate as Jack Williams, or you could choose to trade publicly as Jack's Pool Care.

If Jack trades only as Jack Williams, he generally doesn't need to register a separate business name. If he wants to operate as Jack's Pool Care, he generally needs to register that name.

The same principle applies to other structures. A partnership trading only under the partners' own names may not need a separate business-name registration, while a company can trade under its registered company name without registering another business name.

For example, a company with the legal name Williams Group Pty Ltd could operate under that company name. If it instead wants to trade publicly as Rapid Plumbing Brisbane, it would generally register Rapid Plumbing Brisbane as a business name.

A business name doesn't create a separate legal entity. Registering Jack's Pool Care doesn't create a new company or separate Jack from the underlying business structure.

Your business name also isn't the same thing as your ABN. Your ABN identifies the business or entity, while the business name is the name you trade under. You usually obtain your ABN first and then register the business name against that ABN.

ASIC requires either an ABN or an ABN application reference number before you can register a business name. If you're setting up both at the same time, you can use the Australian Government Business Registration Service.

Business names are registered nationally through the Australian Securities and Investments Commission (ASIC), so you don't need to register the same business name separately in each Australian state or territory.

How to choose a business name

It's worth spending some time choosing and checking a name before paying to register it. For a service business, the name can end up appearing on your ute, uniforms, quotes, invoices, website, advertising and almost every other customer-facing part of the business.

A good business name should ideally be:

• Easy to remember.
• Easy to spell.
• Easy to say.
• Relevant to the business.
• Suitable if the business expands.
• Distinct from competitors.

Think about where the business might go in the future as well as what you're doing today. A name that's extremely specific can sometimes become limiting as your services or service area expand.

For example, North Brisbane Lawn Mowing may work well if lawn mowing in North Brisbane will always be your focus. But if you later expand into landscaping, garden maintenance and property services across a larger area, the name may no longer describe the business particularly well.

Once you have a shortlist, check whether ASIC considers the proposed name available. ASIC's business name availability search can return green for available, amber when assessment is required, or red when the name is unavailable.

A name may be unavailable because it's identical or nearly identical to an existing registered name, contains restricted words or doesn't meet other registration requirements. You can also search the ASIC Business Names Register to see existing registered business names and their holders.

Don't stop at checking whether ASIC technically allows the name. Look at businesses using similar names as well. If you're planning to register Rapid Pool Care and another established pool service in your area trades as Rapid Pool Services, customers could easily confuse the two.

A more distinctive name can be easier to turn into a recognisable brand and may reduce confusion when customers search for you online.

You should also check for existing trade marks. Registering a business name and owning trade-mark rights are two different things, and business-name registration doesn't give you exclusive ownership of the name or brand.

IP Australia provides a free TM Checker that can help small businesses perform an initial search for potentially relevant trade marks.

This is particularly worth doing before investing heavily in vehicle signage, uniforms, advertising, printed materials, logos or a website. Finding out later that your branding conflicts with someone else's trade mark can be much more expensive than checking before launch.

Finally, check whether suitable domain names and social media usernames are available. For example, if you want to call the business Coastal Lawn Care, you might check whether an appropriate .com.au or .au domain is available.

Business-name registration, domain registration and trade-mark rights are separate systems. Registering one doesn't automatically give you rights to the others, so checking them together before settling on the final name can make building the brand much easier later.

How to register a business name in Australia

Once you've chosen a name, checked that it's available and have your ABN or ABN application reference number ready, you can register the business name online.

The process can be broken down into these steps:

1. Get your ABN. You'll need an ABN or an ABN application reference number before registering the business name. If you're starting a new business, you can apply for the ABN and business name through the Australian Government Business Registration Service.
2. Check the name is available. Use ASIC's business name availability search to check your proposed name. If it isn't available, you'll need to choose another. Also check similar businesses, trade marks and suitable domain names before committing.
3. Start your application. For many people starting a new small business, the Australian Government Business Registration Service is a straightforward option. If you already have an ABN, you can also register directly through ASIC.
4. Enter your ABN. The business name will be connected to the entity that holds the ABN. Make sure you're registering it against the correct ABN, particularly if you're involved with more than one business or entity.
5. Enter the business name. Check the spelling carefully before proceeding. You can't simply edit a registered business name later if you decide you want different wording.
6. Choose your registration period. Business names can currently be registered for either one year or three years. You'll need to renew the registration when that period expires if you want to continue using the name.
7. Enter the holder and address details. You'll be asked for information about the person or organisation that will hold the business name, along with relevant addresses and contact information. The exact details depend on your business structure.
8. Review the application. Check the business-name spelling, ABN, holder details, addresses, contact information and registration period carefully before submitting.
9. Pay the registration fee. Business-name registration isn't free. Once the required fee is paid, your application can be processed.

You can start the process through the Australian Government Business Registration Service or follow ASIC's step-by-step registration guidance.

How much does a business name cost and how long does registration take?

Business-name registration isn't free. As of September 2026, the Australian Government lists ASIC's registration fees as:

• $47 for 1 year.
• $108 for 3 years.

Government fees can change, so check the current pricing on the business.gov.au business-name registration page before applying.

The application itself may only take around 10 to 15 minutes when you have the required information ready.

According to business.gov.au, if you've provided the correct information and paid the fee, confirmation should generally be received within:

• 2 business days when paying by credit card.
• 5 business days when paying by BPAY, EFT or bank transfer.

You should wait until the business name appears on the business names register before using it as a registered business name.

What happens after you register your business name?

Registering the name isn't the end of your responsibilities. You'll need to use it correctly, keep your details current and renew the registration if you want to continue using it.

Once registered, your business name should be clearly displayed wherever the business is open to the public. You should also use your registered business name on written business communications such as quotes, invoices, purchase orders and customer correspondence.

ASIC also requires the registered business name and ABN on business documents such as invoices and purchase orders. For a mobile service business without a traditional shopfront, your quotes, invoices, website, emails and other customer-facing materials become particularly important places to keep your business identity consistent.

If you're preparing your first invoices, our guide to creating an invoice in Australia explains the other information Australian invoices and tax invoices may need.

You can read the current business-name display and registration requirements on business.gov.au.

A single ABN can also have more than one registered business name linked to it. For example, one sole trader could potentially operate different services using separate registered business names while the underlying entity remains the same.

Whether operating multiple business names makes sense from an accounting, branding or business-structure perspective depends on the circumstances, but you don't automatically need a separate ABN simply because you register another business name.

If you later decide you want a different name, you can't simply rename the existing registration. You'll generally need to register the new business name, update your branding and business details, and cancel the old name when you no longer need it.

This is another reason it's worth choosing carefully before you register. The Australian Government provides further guidance on choosing and changing a business name.

Your business name also isn't registered permanently. You'll need to renew it after the registration period you selected — either one year or three years.

ASIC generally sends a renewal notice before the renewal date. If you no longer need the name, you can cancel it instead of renewing it. Make sure ASIC has your current contact information so renewal notices don't go to an old email address or postal address.

Does registering a business name protect it?

Not by itself. Registering a business name allows you to trade under that name, but it doesn't give you exclusive intellectual-property rights to the name or brand.

Trade-mark registration is separate and can provide exclusive rights to a name or brand for particular goods and services.

For a small local service business, you may or may not decide that registering a trade mark is worthwhile, but it's still sensible to check for existing trade marks before investing heavily in branding.

IP Australia's TM Checker can be used as a starting point when checking potentially relevant trade marks.

What to do after registering your business name

Once your ABN and business name are sorted, you can move on to the practical work of getting the business ready for customers.

Before you start sending quotes, you'll also need to decide how you're going to price your work. Our guide to pricing a service job without guessing covers labour, materials, costs and margins when working out what to charge.

Once you're ready to start billing customers, our guide to creating an invoice in Australia explains what should go on an invoice, how GST affects tax invoices and the information customers need to pay you.

Other next steps may include:

1. Check whether you need to register for GST.
2. Check licences, permits and trade-specific requirements.
3. Arrange appropriate business insurance.
4. Register a domain name and set up a business email address.
5. Set up a system for creating and managing quotes.
6. Create a basic website or online presence.
7. Set up a way to manage customers, bookings and jobs.
8. Start marketing the business and finding customers.

Once you begin dealing with customers, keep your legal name, registered business name and ABN consistent across your quotes, invoices and other business documents.
