Sole Trader

Last updated 8 October 2026

A sole trader is a type of business structure owned and run by one person. In this setup, there is no legal separation between you and your business, meaning you keep all the profits after tax, but you are also personally responsible for any debts the business incurs.

What it means

When you operate as a sole trader, you are the absolute master of your own business destiny. Setting up as a sole trader is usually the simplest and cheapest way to start working for yourself, requiring very little paperwork compared to forming a limited company.

You simply register with the tax authorities, keep track of your income and expenses, and file an annual tax return. Because the business and the owner are legally the same entity, you have total control over all decisions and direct access to all generated income.

However, this simplicity comes with a major trade-off known as unlimited liability. If your business runs into financial trouble, cannot pay its suppliers, or faces a lawsuit, creditors can go after your personal assets, such as your car or savings.

This means the risk you carry is much higher than if you operated through a registered company, where your personal wealth is usually protected from business debts. In daily practice, managing your finances as a sole trader means keeping clear, accurate records of every penny that comes in and goes out.

You will pay income tax on your net profits rather than a separate corporate tax. Many people start their entrepreneurial journeys as sole traders to test a business idea with minimal overhead costs before deciding to incorporate as their business grows.

Being a sole trader is like riding a unicycle. You have complete control over the direction and speed, but if you wobble and fall, you hit the ground yourself because there is no safety net.

In practice

Real-world examples

Example 1

Sarah works as a freelance graphic designer. As a sole trader, she designs logos for local cafes, keeps all the money she earns, and pays her income tax directly through her annual personal tax return. She buys her design software and a laptop in her own name and claims them as business expenses. When a client pays late, the gap comes straight out of her own pocket.

Example 2

David runs a local mobile car valeting service by himself. He buys his cleaning supplies using his personal savings and pockets all the daily cash takings as his sole source of personal income. Because he has no employees, he does not run a payroll, but he sets aside a share of every job for his tax bill.

Example 3

Maya operates a small independent bookshop as a sole trader. She manages the inventory, serves customers daily, and assumes full personal responsibility for the shop lease and business loans. If sales slump and a publisher's invoice goes unpaid, there is no company to blame, because the debt is legally hers.

Formula

Calculation

Net Profit = Total Business Revenue - Allowable Business Expenses. For example, if a sole trader earns $40,000 in revenue and has $10,000 in allowable expenses like tools and travel, the net profit subject to tax is $30,000 ($40,000 - $10,000). To see what is left after tax, suppose a simple illustrative tax rate of 20% applies to that profit. The tax owed is $30,000 x 20% = $6,000, so the sole trader keeps $30,000 - $6,000 = $24,000 before personal living costs. Real tax systems use bands and allowances, but the principle is the same: you are taxed on profit, not on revenue.

Case study

Seen in the real world

This is a fictional, illustrative scenario. Consider Alex, who started a landscaping business as a sole trader under the name Green Acres. In his first year, Alex generated $50,000 in total revenue from mowing lawns and trimming hedges for residential clients. To run the business, he spent $12,000 on fuel, equipment maintenance, and insurance, giving him a net profit of $38,000.

Because he operated as a sole trader, this $38,000 was treated as his personal taxable income for the year. Alex enjoyed the simplicity of not having to file corporate accounts or pay accountant fees for complex company structures. However, when his ride-on lawnmower broke down beyond repair, costing $6,000 to replace, Alex had to pay for it directly from his personal savings account because the business had no separate cash reserve. This highlighted the direct link between his personal finances and business operations.

In his second year, revenue grew to $70,000 and Alex began to wonder whether to hire a part-time helper and form a limited company. His accountant explained that a company would add filing duties and costs, but could shield his home from claims if a customer ever sued over damaged property. Alex bought proper liability insurance straight away and decided to revisit incorporation once his profits justified the extra paperwork.

Watch out

Common mistakes

  • Mixing personal and business money by using the same bank account for everything.
  • Failing to save money throughout the year to pay the annual income tax bill.
  • Not realising that personal assets are at risk if the business fails.

Questions

People also ask

Do I need a business bank account as a sole trader?

It is not always legally required, but it is strongly recommended to keep your personal and business transactions separate for clear tax reporting.

How do I pay myself as a sole trader?

You do not pay yourself a salary. Instead, you simply take money out of the business bank account whenever you want, as all profits belong to you.

When should I switch from a sole trader to a limited company?

Many business owners make the switch when their profits grow high enough that forming a company becomes more tax-efficient or to protect personal assets.
