What is a sole trader?

Starting a microbusiness or side-hustle in Australia often begins with a simple question: what legal form should you use? A sole trader is the simplest business structure — one person runs and owns the business, keeps the profits, and is personally responsible for debts and legal obligations. This guide explains what a sole trader is in Australia, the practical and tax implications, and the day-to-day steps to set up and run one.

Key features of a sole trader

• Single owner and controller: You make the decisions and receive all profits after tax.
• Legal identity: There is no separate legal entity — you and the business are the same for contracts and debts.
• Unlimited personal liability: Business debts and legal claims can be enforced against your personal assets.
• Taxed at personal rates: Business income is included in your personal tax return and taxed at your marginal rates.
• Simple to set up and wind up: Lower set-up and administration costs compared with a company or trust.
• ABN and business name: You typically need an ABN to trade; register a business name if you trade under a name other than your personal name.
• GST and PAYG obligations: You may need to register for GST if you meet the threshold and manage PAYG withholding if you employ staff.

When considering finance or asset purchases, note there are many funding and lending options available, such as invoice finance, asset finance, and secured business loans.

Advantages and disadvantages

Advantages

• Simplicity and control: Quick to set up, low ongoing compliance, and full control of operations and profits.
• Lower compliance costs: No separate company tax return or director obligations — simpler reporting.
• Tax simplicity for small operations: Losses can generally be offset against other personal income (subject to anti-avoidance rules).
• Flexible income use: You can draw funds as needed without formal salary arrangements.

Disadvantages

• Unlimited personal liability: You're personally liable for debts, leases and legal claims; creditors can pursue your personal assets.
• Perception and growth limits: Some suppliers, clients or lenders prefer a company structure for larger contracts or lending.
• Tax inefficiency at scale: As profits grow, paying personal marginal rates may be higher than the company tax rate.
• Access to capital: Raising equity or attracting investors is harder than for a company; lenders may require personal guarantees.

A sole trader is ideal for low-risk, owner-operated businesses and testing ideas. If you plan to scale, hire many staff, or seek investors, consider alternative business structures or financing paths available to support your growth.

How to set up as a sole trader — step by step

1. Check licences and industry rules
   • Visit business.gov.au for required licences and permits relevant to your trade. Some trades require professional registration or state licences.

2. Apply for an ABN
   • Apply for an ABN via the Australian Business Register and review ABR eligibility advice for sole traders.

3. Register a business name (if needed)
   • If you trade under a name other than your personal name, register it with the Australian Securities & Investments Commission (ASIC) or the ABR.

4. Decide on GST registration
   • Monitor your turnover. If your GST turnover will be $15,000 or more per year, you must register for GST. Check the ATO for current thresholds.

5. Set up a business bank account
   • Keep business revenue and expenses separate for clear records and to support tax deductions.

6. Organise insurance
   • Obtain relevant policies: public liability, professional indemnity, and workers' compensation if you employ staff.

7. Put bookkeeping in place
   • Use cloud accounting software (e.g., Xero, MYOB) to manage invoicing, GST and BAS. Onboarding a simple chart of accounts and monthly reconciliation saves time.

8. Understand payroll and super obligations
   • If you hire, register for PAYG withholding and understand employer super obligations.

9. Plan for tax and BAS reporting
   • Decide BAS frequency (monthly or quarterly) and whether to pay PAYG instalments. Keep tax records and lodge on time.

In your first 30 days, get an ABN, a business bank account, and basic insurance. By month 2–3, set up accounting software, register for GST if expected turnover approaches $15,000, and implement basic invoicing and receipts procedures.

Tax and reporting obligations

ABN vs TFN: An ABN identifies your business to clients and suppliers; your TFN is used for your personal tax return.

Income taxed at personal rates: Business profit is added to your other income and taxed at your marginal rates — there is no separate company tax.

GST (Goods and Services Tax):

• Threshold: register if GST turnover is $15,000 or more (check the ATO for updates).
• When registered, you add 10% GST to taxable sales, can claim credits for GST paid on business purchases, and must lodge a BAS.
• BAS frequency: monthly or quarterly depending on turnover and ATO settings.
• Example: if you invoice $1,100 including GST, $100 is GST payable on the BAS; you can claim GST credits on eligible purchases.

BAS vs tax return: BAS reports GST, PAYG withholding, and other instalments; it does not replace your annual personal tax return, where business profit is declared.

PAYG withholding: If you employ staff, you must withhold tax from wages and remit to the ATO. You may also pay PAYG instalments on expected tax liabilities.

Income splitting and family payments: Payments to family must reflect commercial reality; artificial income splitting to reduce tax can attract ATO attention.

Record retention: Keep tax and business records (invoices, receipts, bank statements) for at least five years as required by the ATO.

See detailed guidance from the ATO and business.gov.au. For tax planning or complex situations, consult an accountant.

Sole trader vs company or trust — quick comparison

• Liability: Sole trader = unlimited personal liability; company = limited liability for shareholders (subject to director duties).
• Tax: Sole trader taxed at personal marginal rates; companies taxed at company rates (may be advantageous as profits grow).
• Compliance: Companies have higher compliance costs and reporting obligations than sole traders.
• Investment and scale: Companies and trusts are typically better for attracting investment and managing complex ownership.

If you're deciding between structures, get tailored advice from an accountant on business structure options.

Superannuation and employees

Employer super obligations: If you employ staff, you must pay the Superannuation Guarantee (SG) for eligible employees at the SG rate on ordinary time earnings and report these payments.

Sole trader's own super: There is no legal requirement for you as a sole trader to pay super to yourself; however, making personal super contributions is a common retirement strategy and may attract tax concessions.

Contractors vs employees: If a worker is genuinely a contractor, you generally don't pay their super; however, modern awards and rules (and the ATO's tests) determine classification. Misclassification can create liabilities for unpaid super and PAYG.

Payroll setup: Use payroll in your accounting software to track super liabilities, STP reporting and pay periods.

Hiring people and subcontractors

Employee vs contractor distinction: Assess the nature of the working relationship — control, independence, equipment provision, and whether the worker invoices you.

PAYG and Super:

• For employees: withhold PAYG, pay super, and meet workers' compensation requirements.
• For contractors: obtain their ABN and a written contract; do not withhold tax if they quote an ABN, unless they fail to provide one.

Payroll obligations: Register for PAYG withholding, report via Single Touch Payroll (STP), and issue pay slips.

Insurance and WHS: Workers' compensation insurance and compliance with workplace health and safety rules are mandatory when you employ staff.

Recordkeeping: Keep contracts, timesheets and payment records to demonstrate compliance.

Insurance and risk management

Because you have unlimited personal liability, insurance is a critical protection layer:

• Public liability: Covers third-party injury or property damage from your business activities.
• Professional indemnity: Important if you provide advice or professional services.
• Business interruption: Compensates lost income when a covered event interrupts operations.
• Tools and contents: Covers business equipment and stock.
• Workers' compensation: Mandatory if you have employees.
• Consideration for contracts: Larger clients may request minimum insurance levels.

Insurance reduces the risk that a business claim or debt will force you to sell personal assets. Combine insurance with clear contracts and risk assessments.

Record-keeping and bookkeeping essentials

Core records to keep:

• Sales invoices and receipts, purchase invoices, bank statements, credit card statements, payroll records, BAS statements and tax returns.

Retention period:

• Keep records for at least five years (ATO guidance).

Recommended workflow:

• Daily or weekly: record sales and expenses digitally.
• Monthly: reconcile bank accounts, review profit and loss.
• Quarterly: lodge BAS (if quarterly) and review cashflow.

Software and automation:

• Use cloud accounting tools, automated bank feeds and receipt capture to reduce errors.

Common mistakes:

• Mixing personal and business bank accounts, failing to track GST on purchases, under-documenting cash sales, and late BAS lodgements.

Good bookkeeping supports tax compliance, borrowing applications and strategic decisions. If you seek financing for growth, lenders will want 12–24 months of organised financials.

When to consider changing structure

Signs you should speak to an adviser about switching to a company or trust:

• Growing profits: When retained profits would be taxed more efficiently in a company.
• Want to limit liability: If clients or contracts require limited liability.
• Raising capital or taking on investors: Companies or trusts are usually preferable.
• Hiring many employees: To separate personal risk and implement formal governance.
• Complex ownership: If you want to split income among family members or partners.

Next steps: review business structure options with an accountant, run scenarios, and consider implications for tax, reporting and transfer of assets.

Common mistakes to avoid

• Mixing personal and business finances — open a business account immediately.
• Failing to register for GST when turnover nears the $15,000 threshold.
• Under-insuring your business given unlimited personal liability.
• Poor record-keeping leading to missed deductions and penalties.
• Misclassifying workers as contractors to avoid PAYG and super obligations.
• Delaying advice when your business outgrows the sole trader model.

Quick checklist: Starting and running a sole trader business

• Check licences and register a business name if needed.
• Set up a business bank account.
• Decide whether to register for GST.
• Put bookkeeping and invoicing in place.
• Organise basic insurance (public liability, professional indemnity).
• If hiring, register for PAYG and set up payroll.
• Keep records for at least five years and lodge BAS and tax on time.
