How it works in practice

Understanding a Sole Trader

A sole trader is the simplest and most common business structure in Australia, where an individual directly owns and operates their business. There's no legal distinction between the individual and the business; you are legally the same entity. This means you use your personal Tax File Number (TFN) for income tax purposes, though you will generally need an Australian Business Number (ABN) to operate. As a sole trader, you are personally liable for all business debts and obligations.

Taxation for Sole Traders

Sole traders pay income tax on the profits their business earns through their personal income tax return. Business income and expenses are reported in a dedicated section of the individual tax return. This means you consolidate your business income with any other personal income (like salary or investments) and pay tax at individual income tax rates. You can claim deductions for eligible business expenses. Sole traders may also need to register for Goods and Services Tax (GST) if their annual business income (gross income less GST) reaches or exceeds the current threshold (currently $75,000, or $150,000 for non-profit organisations). You are typically responsible for making Pay As You Go (PAYG) instalments towards your income tax throughout the year.

Important exceptions

The definition and taxation of a sole trader apply unless you choose a different business structure like a partnership, company, or trust, each with its own legal and tax implications. While generally simple, specific industry regulations might impose additional requirements. Additionally, the GST threshold and income tax rates are subject to change by the Australian government, impacting your tax obligations.

What you should do now

  1. Apply for an Australian Business Number (ABN) if you don't already have one, as it's essential for invoicing and tax purposes.

  2. Register for Goods and Services Tax (GST) with the ATO if your projected annual business income will meet or exceed the current threshold.

  3. Set up a separate bank account for your business to easily track income and expenses, simplifying your record-keeping.

  4. Keep accurate and detailed records of all business income and expenses, including receipts and invoices, for tax compliance.

  5. Consult with a tax professional or the ATO for personalised advice on your specific tax obligations, including PAYG instalments.
