Thinking about starting a business on your own? In Australia, one of the simplest ways to begin is as a sole proprietor - commonly called a sole trader.
It’s popular because you can get up and running quickly, costs are low, and you keep full control over decisions and profits.
However, there are important legal and practical considerations to understand before you jump in. In this guide, we’ll explain what a sole proprietorship is, how it compares to a company, the steps to set up, the key laws you’ll need to follow, and the essential documents to protect your business.
What Does “Sole Proprietorship” Mean In Australia?
A sole proprietorship (sole trader) is a business structure where one individual owns and runs the business. There’s no separate legal entity - you and the business are the same person for legal and tax purposes.
This means you receive all the profits, but you also carry all the risks and debts personally. If something goes wrong (for example, a dispute or unpaid debt), your personal assets may be on the line.
You can still hire employees and engage contractors as a sole trader. You can also trade under your own name or under a registered business name (more on registration below). Day to day, a sole trader business can look just like any other small business - the difference is in how it’s set up legally and how liability sits with you personally.
Sole Trader Vs Company: Which Structure Should You Choose?
Choosing a structure is one of your most important early decisions. Here’s how a sole trader stacks up against a company.
Key Differences
- Liability: As a sole trader, you’re personally liable for business debts and claims. A company is a separate legal entity, which means limited liability for owners in most cases.
- Cost & Complexity: Sole trader setup is quick and low-cost. A company has more setup steps, ongoing reporting obligations, and compliance requirements, but offers stronger separation between personal and business matters.
- Tax: Sole traders are taxed as individuals at personal tax rates. Companies pay tax at the company tax rate, and directors/shareholders then consider how they pay themselves (e.g. salary/dividends). Get tailored tax advice to understand what’s best for your situation.
- Growth & Investment: If you’re bringing in co-founders or investors, a company structure is usually more suitable, as you can issue shares and formalise ownership and control.
For many new ventures, starting as a sole trader makes sense because it’s simple. If your risk increases or your business grows, you can transition to a company later. If you think you’re ready to incorporate now, explore our Company Set Up options to understand what that involves.
Business Name Vs Personal Name
You can trade under your own personal name without registering anything further. If you want to trade under a name that isn’t your exact personal name (for example, “Coastal Creative Studio”), you’ll need to register a business name. Registering a business name allows you to brand your business, open business bank accounts, and present professionally in the market.
What About Getting an ABN?
Most sole traders apply for an Australian Business Number (ABN) to issue invoices and deal with other businesses. An ABN also helps with GST registration if required. Many owners consider the ABN pros and cons early so they understand when it’s needed and how it impacts their operations.
How Do You Set Up As A Sole Trader? (Step-By-Step)
Getting started is straightforward. Here’s a practical roadmap to follow.
1) Plan Your Business
Even micro-businesses benefit from a simple business plan. Clarify what you’re selling, who your ideal customer is, how you’ll price your offerings, and how you’ll market yourself.
Map your key risks too - for example, customer non-payment, supplier delays, or data security - and note how you’ll manage them with contracts, processes, and insurance.
2) Apply For Your ABN
Most sole traders apply for an ABN so they can invoice, register for GST (if required), and identify the business with government agencies and suppliers. You’ll also provide your Tax File Number (TFN) for income tax purposes.
3) Decide On Your Trading Name
If you’re trading under your personal name only, you can skip this step. If you want to trade under a different name, register a business name so customers and suppliers can find and recognise you. This also helps with bank accounts, invoicing, and branding.
4) Set Up Business Essentials
- Banking: Open a separate business bank account so your business income and expenses are clearly tracked.
- Bookkeeping: Choose an accounting system to record invoices, expenses, and tax. This makes BAS and tax time much easier.
- Insurance: Consider insurance appropriate to your industry (for example, public liability, professional indemnity). A broker can help you find the right cover.
- Digital Presence: Secure your domain name, set up your website and socials, and put in place basic legal policies for your site (covered below).
5) Put Your Core Legal Documents In Place
Before you start trading, make sure your key contracts and policies are ready. Having your terms, privacy settings, and employment/contractor agreements sorted from day one reduces disputes and improves your cash flow.
6) Understand Your Tax And Reporting
Work with an accountant to understand your obligations, including income tax, GST (if your turnover is or will be at or above the GST threshold), and PAYG if you hire staff. Set calendar reminders for lodgements so you stay on top of deadlines.
What Laws Do Sole Proprietors Need To Follow?
Running a business in Australia means complying with a range of laws. The specifics depend on your industry and how you operate, but the following areas are common to most sole traders.
Australian Consumer Law (ACL)
If you sell goods or services to consumers, the Australian Consumer Law applies to how you advertise, handle refunds, set warranties, and communicate with customers. Clear, fair terms and honest marketing are essential. If you need support with compliance and policies, our consumer law team can help tailor your approach.
Privacy And Data Protection
If you collect personal information (for example, names, email addresses, phone numbers, order details), you should implement a transparent Privacy Policy and handle data securely in line with Australian privacy standards. This is especially important if you operate online or run email marketing.
Contracts And Fair Dealing
Always use clear written contracts with customers and suppliers to reduce the risk of disputes. Unfair contract terms can be unenforceable, so keep your terms balanced and easy to understand.
Employment And Workplace Law
If you hire staff, you must comply with the Fair Work framework, including minimum wages, leave entitlements, safe workplace standards, and proper onboarding. Put a compliant Employment Contract and basic workplace policies in place before anyone starts.
Intellectual Property (Brand Protection)
Registering your brand name or logo as a trade mark gives you stronger, Australia-wide rights and can stop others from using a confusingly similar brand. Consider applying to register your trade mark once you’ve settled on your name and brand assets.
Business Permits And Local Rules
Depending on your activity and location, you may need local council permits (for signage, home businesses, or outdoor trading), industry-specific licences, or health and safety approvals. Check what applies before you start trading to avoid fines or delays.
Tax And Record-Keeping
Maintain accurate financial records, set aside tax and GST as you go, and lodge returns on time. Good record-keeping isn’t just a legal obligation - it also helps you understand your profitability and make better decisions.
What Legal Documents Should A Sole Trader Have?
You don’t need a mountain of paperwork to run as a sole proprietor, but a few well-drafted documents go a long way in protecting your time, cash flow, and reputation.
- Customer Contract or Terms: A clear Customer Contract sets out scope, pricing, payment terms, timelines, and what happens if something changes or goes wrong. This reduces scope creep and helps you get paid on time.
- Privacy Policy: If you collect personal information, a transparent Privacy Policy explains what you collect, why you collect it, and how customers can contact you about their data.
- Website Terms: If you have a website or online store, Website Terms/Terms of Use outline acceptable use, IP ownership, and limits of liability. These sit alongside your customer terms or product/service pages.
- Quotes/Scopes/Statements of Work: For project-based work, attach a scope or SOW to your customer contract. This clarifies deliverables, milestones, and change control.
- Employment or Contractor Agreements: If you bring on help, use a compliant Employment Contract for employees, or a Contractor Agreement for contractors. This defines duties, pay, IP ownership, confidentiality, and termination.
- Supplier Agreements: If you rely on suppliers or wholesalers, set terms around delivery, quality, warranty, and risk to avoid finger-pointing later.
- IP And Branding: If brand is important to your growth, consider trade mark registration to lock in exclusive rights - you can start with trade mark protection for your name and logo.
Well-structured contracts also help you present professionally and streamline sales. They signal to customers and partners that you run a serious business and that there are clear expectations on both sides.
Can You Move From Sole Trader To A Company Later?
Yes. Many businesses begin as sole traders and incorporate once they grow, hire more staff, or take on larger contracts. Common triggers for switching include wanting limited liability, bringing in co-founders or investors, or planning to sell the business down the track.
If you do transition, you’ll need to set up the company, move key assets and contracts across, and update registrations and bank accounts. Planning this change with a lawyer and an accountant makes the process smoother and helps you avoid issues like double registrations or gaps in insurance and contracts. If you’re weighing this up now, our Company Set Up services can walk you through what’s involved.
