Starting as a sole trader in Australia is like embarking on your own business adventure. It's the simplest way to test your entrepreneurial waters, with minimal red tape and maximum control over your destiny. But with that freedom comes responsibility, and understanding what you're signing up for can mean the difference between thriving and merely surviving.
Whether you're considering making the leap from employee to business owner, or you're already trading and want to ensure you're doing everything right, this guide covers everything you need to know about operating as a sole trader in Australia.
A sole trader, also known as an individual proprietor, is someone who runs their business independently without forming a company or partnership. It's the most straightforward business structure in Australia, where you and your business are legally the same entity.
This simplicity is both the greatest advantage and the biggest risk of sole trading. You have complete control over your business decisions, keep all the profits, and can start trading immediately. However, you're also personally liable for all business debts and legal obligations.
These professionals enjoy the flexibility to set their own hours, choose their clients, and pivot quickly as market conditions change.
As a sole trader, there's no legal separation between you and your business. This means:
This direct relationship simplifies many aspects of running a business but requires careful financial management to protect your personal assets.
You can trade under your own name without any registration requirements. However, if you want to use a different business name, you'll need to register it through ASIC (Australian Securities and Investments Commission).
Business name registration costs around $40 for one year or $95 for three years. The name must be unique and not misleading to consumers.
An ABN is essential if you're earning business income and is required for GST registration. You can apply for an ABN free of charge through the Australian Business Register website.

The ATO will automatically notify you if PAYG instalments are required based on your previous year's tax return.

To create a valuable business asset:
Q: Do I need an ABN to work as a sole trader?
A: Yes, you need an ABN if you're earning business income as a sole trader. It's free to obtain and essential for issuing invoices, avoiding tax withholding, and accessing various business services and registrations.
Q: Can I employ staff as a sole trader?
A: Yes, sole traders can employ staff, but this creates additional obligations including payroll tax, workers' compensation insurance, superannuation guarantee payments, and compliance with Fair Work regulations.
Q: What's the difference between a sole trader and a company?
A: The main differences are legal liability (personal vs limited), tax treatment (personal rates vs company tax), setup complexity (simple vs formal registration), and ongoing compliance requirements (minimal vs extensive reporting).
Q: Do I need to register for GST immediately?
A: You must register for GST within 21 days of your turnover reaching $75,000. If starting a new business expecting to reach this threshold, register before you start trading. Voluntary registration is also possible for businesses below the threshold.
Q: Can I claim home office expenses as a sole trader?
A: Yes, you can claim a portion of home expenses including rent/mortgage interest, utilities, insurance, and maintenance costs. You can use either the simplified method (67 cents per hour) or calculate actual costs based on the percentage of home used for business.
Q: How often do I need to lodge a BAS as a sole trader?
A: If registered for GST, you'll lodge BAS returns monthly or quarterly depending on your turnover and election. Small businesses typically lodge quarterly, while larger businesses may be required to lodge monthly.
Q: What happens if I don't keep proper business records?
A: Poor record keeping can result in lost tax deductions, ATO penalties, difficulty accessing business loans, and problems if you're audited. You must keep records for five years, including income records, expense receipts, and bank statements.
Q: Can I change from sole trader to company later?
A: Yes, you can change business structure, but this involves closing your sole trader business and starting a new company. This has tax implications and should be planned carefully with professional advice to minimise complications.
Q: Do I need separate business bank accounts as a sole trader?
A: While not legally required, separate business accounts are highly recommended for better record keeping, easier tax preparation, professional credibility, and clearer financial management. Most banks offer competitive business account options for sole traders.
Q: What insurance do I need as a sole trader?
A: Essential insurances include public liability (for third-party claims), professional indemnity (for service-based businesses), and income protection (for personal injury). Product liability insurance is crucial if you manufacture or sell goods. Requirements vary by industry.
