Quick Answer

To start a sole trader business in Australia, you need a Tax File Number, an Australian Business Number (ABN), and — if trading under a name other than your own — a registered business name through ASIC. You’ll also need to register for GST if your turnover reaches $75,000 or more. Beyond registration, building a credible business means establishing your brand, getting online, and setting up the operational basics covered in this guide.

This guide provides general information only and isn’t a substitute for advice from an accountant, tax agent, or legal professional. Always confirm current requirements and fees directly with the Australian Business Register, ASIC, and the ATO before registering.

What Is a Sole Trader?

A sole trader is the simplest business structure in Australia — you, as an individual, own and run the business. There’s no separate legal entity between you and your business, which means it’s straightforward and low-cost to set up, but it also means you’re personally responsible for all business debts and obligations.

This structure suits freelancers, tradespeople, consultants, and many small service or product-based businesses, particularly in the early stages before growth might justify a company structure.

Step 1: Get a Tax File Number (TFN)

You’ll need a personal TFN before registering as a sole trader — it links your business activities to your individual tax record. Most Australian residents already have one from previous tax returns. If you don’t, you can apply through the ATO.

Step 2: Apply for an ABN

Your Australian Business Number (ABN) is an 11-digit identifier that’s essential for invoicing clients, avoiding higher tax withholding on payments, and presenting your business professionally. ABN registration is free and can be completed online through the Business Registration Service, typically within the same session as your business name and GST registration if needed.

You’ll generally need: your TFN, proof of identity details, your business address, and a clear description of what your business actually does.

Step 3: Decide If You Need a Registered Business Name

If you plan to trade under your own legal name (e.g. “Sarah Chen”), no business name registration is required. If you want to trade under a different name (e.g. “Chen Consulting” or “Perth Property Styling”), you’ll need to register that name with ASIC.

Registration fees do change periodically, so confirm the current cost directly on the ASIC business name registration page rather than relying on a fixed figure here.

Step 4: Register for GST (If Applicable)

GST registration becomes mandatory once your annual turnover reaches $75,000. It’s optional below that threshold, though some sole traders choose to register early if they want to claim GST credits on business purchases. If you register for GST, you’ll need to lodge regular Business Activity Statements (BAS).

Step 5: Set Up Your Business Banking and Bookkeeping

While not legally required for sole traders (unlike companies), a separate business bank account makes it far easier to track income, expenses, and tax obligations — and looks more professional to clients. Pairing this with basic bookkeeping software from day one avoids a stressful scramble at tax time.

Step 6: Consider Business Insurance

Depending on your industry, you may need or want public liability insurance, professional indemnity insurance, or industry-specific cover. This is worth discussing with an insurance broker familiar with your specific trade or service.

Step 7: Build a Brand That Looks Credible From Day One

This is where many new sole traders underinvest — and it’s often where it matters most. In competitive markets, a professional, considered brand is one of the fastest ways to build trust with new customers who don’t have a prior relationship with you yet.

At minimum, this means:

A logo that reflects your business and works everywhere it needs to — see our guide on what makes a logo effective, or explore our logo design services
A consistent visual identity — colours, fonts, and tone that stay recognisable across your website, invoices, and social media. Our complete guide to branding covers this in more depth, and our branding services can help build it properly from the start

Step 8: Get a Professional Website

For most sole traders, your website is the first real impression a potential customer forms of your business — often before they ever speak to you directly. A DIY or template-based site can work temporarily, but as you grow, the limitations tend to show.

If you’re offering services, see our web design or our breakdown of how to choose the right platform for your business
If you’re planning to sell products online, WooCommerce is one of the most flexible platforms available — our guide on what WooCommerce actually is is a good starting point
Whichever platform you choose, building on WordPress from the outset gives you room to grow without needing to rebuild later

Step 9: Plan for Ongoing Maintenance, Not Just Launch

A website (and a business generally) isn’t a “set and forget” asset. Once you’re live, regular website maintenance — security updates, backups, performance checks — protects the investment you’ve just made. Our website maintenance checklist is a useful reference for what to check and how often.

Common Mistakes New Sole Traders Make

Delaying an ABN until it’s urgently needed — this can mean higher tax withholding on early payments
Skipping a business bank account — makes bookkeeping and tax time significantly harder
Underinvesting in branding and web presence early — first impressions are hard to undo once formed
Not budgeting for insurance — a single incident without cover can be financially serious for a sole trader, given the lack of separation between personal and business liability

Frequently Asked Questions

Do I need an ABN to be a sole trader in Australia? Yes, an ABN is essential for invoicing clients correctly, avoiding higher tax withholding, and operating professionally, even if your turnover is below the GST threshold.

How much does it cost to register as a sole trader? Getting an ABN is free. A registered business name (only needed if trading under a name other than your own) has a small registration fee, which is best confirmed directly on ASIC’s website since rates are periodically updated.

Do I need to register for GST straight away? Only if your annual turnover reaches, or is expected to reach, $75,000. Below that, registration is optional.

Is being a sole trader the same as owning a company? No. A sole trader has no legal separation between themselves and the business, meaning personal assets can be at risk from business debts. A company is a separate legal entity, offering more protection but with more setup and compliance requirements.

What’s the first thing I should set up after registering my ABN? Most new sole traders benefit from prioritising a business bank account and a professional website early, since both directly affect how credible your business looks to new customers from day one.
