Sole Trader Setup Checklist Australia

Most sole traders need an Australian Business Number (ABN) before they can start issuing invoices to clients. Without an ABN, clients are required to withhold tax from payments at the top marginal rate. An ABN is also required to register for GST, register a business name with ASIC, claim fuel tax credits, and interact with the ATO and other government agencies in a business capacity. ABN registration is free and is completed online through the Australian Business Register.

As a sole trader, you use your personal Tax File Number (TFN) — not a separate business TFN — to report your business income. Business income is reported on your individual income tax return each year. You will report your total business income and claim deductions for business expenses to arrive at your taxable business income. The ATO uses your TFN to match your reported income against data from clients, banks and other sources.

You can trade as a sole trader under your own legal name (e.g. Jane Smith) without registering a business name. However, if you want to trade under a different name (e.g. "Jane Smith Consulting" or "Bright Star Design"), you must register that business name with ASIC. Business name registration is separate from ABN registration and involves an annual or three-year fee. Check the ASIC Business Names Register to confirm your chosen name is available before registering.

If your projected annual business turnover reaches or exceeds $75,000 (or $150,000 for non-profit organisations), you are generally required to register for GST. Once registered, you must add 10% GST to your prices (where applicable), lodge regular Business Activity Statements (BAS) and remit the GST collected to the ATO. Even if you are under the threshold, you can voluntarily register for GST — which allows you to claim GST credits on business purchases. Check the current GST threshold and your specific obligations with the ATO.

While not legally required, maintaining a separate business bank account is strongly recommended for all sole traders. Mixing personal and business finances makes record keeping significantly harder, complicates your tax return preparation, and can create issues if the ATO ever reviews your returns. A dedicated business account makes it easier to track income and expenses, reconcile payments and demonstrate the legitimacy of your business expenditure.

Tax invoices are a legal requirement for GST-registered businesses and a professional best practice for all sole traders. A tax invoice must include your ABN, business name, the date, a description of the goods or services provided, the amount charged, and if GST-registered, the GST component. Invoices are also part of your legal business records and must be kept for at least five years. Using accounting software or a professional invoice template ensures your invoices meet ATO requirements.

As a sole trader, your business income is taxed as personal income. This means your total income — from both employment (if applicable) and business activities — is combined and taxed at individual marginal tax rates. You will need to lodge an individual tax return each year including a business and professional items schedule. Many sole traders pay PAYG (Pay As You Go) instalments quarterly to spread their tax liability throughout the year. Consider working with a registered tax agent if your tax affairs are complex.

Insurance needs vary by industry, but many sole traders should consider public liability insurance (which covers claims from third parties for injury or property damage) and professional indemnity insurance (which covers claims arising from professional advice or services provided). Some clients and industries require proof of appropriate insurance before engaging a contractor or service provider. Compare policies from reputable Australian insurers and verify your industry's specific requirements.

A professional website, business email address and relevant social media profiles are increasingly important for sole traders in most industries. Your website serves as a digital business card, builds credibility with potential clients, and can attract organic search traffic. A business email address (rather than a personal Gmail or Hotmail) signals professionalism. Social media presence on the platforms your target clients use can be an effective and low-cost marketing tool.

The ATO requires sole traders to keep financial records for a minimum of five years. This includes all invoices you issue, receipts for business expenses, bank statements, tax returns and any contracts or agreements related to your business activities. Good record keeping is not just a legal requirement — it is essential for managing your business, preparing your tax return accurately, and substantiating deductions if the ATO questions your claims.
