Sole Trader vs Employee: Understanding the Distinction

The distinction between a sole trader (independent contractor) and an employee is one of the most important — and most frequently misunderstood — issues in the disability sector. Getting it wrong has serious consequences: for workers, it means losing entitlements; for providers, it means potential penalties for sham contracting.

The ATO and the Fair Work Ombudsman assess the true nature of the working relationship, not just what the contract says. Key factors that indicate a genuine sole trader arrangement include:

Factor Employee Indicator Sole Trader Indicator
Control Employer controls how, when, and where work is done Worker decides how to complete the work
Clients Works exclusively for one provider Has multiple clients or is free to accept work from others
Equipment Employer provides tools, equipment, uniforms Worker provides their own tools and equipment
Financial risk No financial risk — paid regardless of business profitability Bears financial risk — responsible for own expenses, insurance, bad debts
Substitution Must perform work personally Can delegate or subcontract work to others
Integration Work is integral to the employer's business Worker operates an independent business providing services

In the NDIS context, a genuine sole trader typically manages their own client relationships, sets their own rates (within NDIS price guide limits), chooses when and how to work, has multiple participants or works across multiple providers, and manages their own business administration.

Setting Up as an NDIS Sole Trader

If you have confirmed that a sole trader arrangement is appropriate for your situation, here are the steps to set up your business.

Step 1: Apply for an ABN

An Australian Business Number (ABN) is essential. You cannot invoice participants or plan managers without one. Apply online at abr.gov.au — it is free and you will usually receive your ABN immediately.

When applying, you will need your tax file number (TFN), personal details, and a description of your business activity. Select "Health Care and Social Assistance" as your industry and describe your activity as "Disability support services" or "NDIS support worker services."

Step 2: Register a Business Name (Optional)

If you want to operate under a name other than your personal name (e.g., "Smith Support Services"), you need to register a business name with ASIC. Registration costs approximately $44 for one year or $102 for three years. If you operate under your own name, business name registration is not required.

Step 3: Open a Business Bank Account

While not legally required for sole traders, a separate business bank account makes financial management dramatically easier. It separates business income and expenses from personal transactions, simplifies BAS preparation, and creates a clear audit trail for the ATO. Most banks offer fee-free business transaction accounts for sole traders.

Step 4: Get Your Screening and Certifications

Step 5: Set Up Record Keeping

The ATO requires you to keep business records for five years. At minimum, you need to track:

Cloud accounting software like Xero, MYOB, or QuickBooks makes record keeping significantly easier. Many offer sole trader plans from $10-$30 per month. Free options like Wave Accounting can work for very simple businesses.

GST, Tax, and Record Keeping

GST Registration

You must register for GST if your annual turnover (gross income, not profit) is $75,000 or more. Below this threshold, GST registration is optional.

There is an important nuance for NDIS services: most NDIS supports are GST-free under Division 38 of the A New Tax System (Goods and Services Tax) Act 1999. This means even if you are registered for GST, you generally do not charge GST on NDIS support services. The GST-free treatment applies where the support is provided under the NDIS and the participant's plan.

However, being GST-registered can still be beneficial because you can claim GST credits (input tax credits) on your business purchases — insurance premiums, equipment, training courses, and other business expenses that include GST. If your business expenses are significant, the GST credits may outweigh the administrative burden of quarterly BAS lodgements.

Income Tax

As a sole trader, your business income is reported on your personal tax return. You pay income tax at individual rates on your net business income (gross income minus allowable deductions). There is no separate business tax return for sole traders — everything goes on your individual return.

Key tax obligations:

Common Tax Deductions

Expense Deductible? Notes
Public liability insurance Yes 100% deductible as a business expense
Professional indemnity insurance Yes 100% deductible
First Aid and CPR courses Yes Training directly related to your business
NDIS Worker Screening Check fee Yes Required for your business to operate
Vehicle expenses Partial Business-use portion only. Keep a logbook for 12 weeks to establish the percentage
Mobile phone and internet Partial Business-use portion only
Accounting software Yes Xero, MYOB, QuickBooks subscriptions
Tax agent fees Yes Deductible in the year they are incurred
Home office expenses Partial If you use a dedicated area for business administration
Tax Tip

Consider using a registered tax agent for your first year as a sole trader. They can ensure you claim all allowable deductions, set up your record keeping correctly, and advise on PAYG instalment obligations. A tax agent typically costs $200-$500 for a sole trader return — and the fee is itself tax-deductible.

NDIS Registration as a Sole Trader

A common question for sole traders is whether they need to register with the NDIS Commission. The answer depends on who you want to provide supports to and what types of supports you offer.

When Registration Is Not Required

If you only provide supports to self-managed and plan-managed participants, NDIS registration is not mandatory. Self-managed participants choose and pay their own providers. Plan-managed participants have a plan manager who pays providers on their behalf. Both can use unregistered providers.

Many sole traders operate successfully without registration, building their client base through platforms like Hireup, word of mouth, and direct referrals.

When Registration Is Required

You must be a registered NDIS provider if you want to provide supports to agency-managed participants (whose funding is managed by the NDIA), or if you want to deliver certain regulated supports such as SIL, specialist disability accommodation, or behaviour support.

Registration as a sole trader follows the same process as for larger organisations:

  1. Complete the NDIS Commission's online application
  2. Undergo a quality audit (verification or certification depending on registration groups)
  3. Meet all applicable NDIS Practice Standards
  4. Maintain ongoing compliance, including incident reporting and complaints management

The cost of registration can be significant for a sole trader — audit fees alone range from $3,000 to $10,000+ depending on the registration groups. This is why many sole traders choose to remain unregistered and focus on self-managed and plan-managed participants.

Invoicing NDIS Participants

Accurate invoicing is essential for getting paid and maintaining professional relationships with participants and plan managers.

What Your Invoice Must Include

NDIS Price Guide Compliance

Whether you are registered or unregistered, the NDIS Price Guide sets maximum prices for most support categories. You can charge less than the Price Guide rates but not more. The Price Guide is updated annually by the NDIA — ensure you are using the current version when setting your rates and preparing invoices.

When invoicing plan managers, accuracy is critical. Plan managers process high volumes of invoices and will reject invoices that do not include correct NDIS support item numbers, or that exceed Price Guide rates. Common rejection reasons include missing NDIS numbers, incorrect support item codes, and rates that exceed the published limits.

Service Agreements

Before providing supports, you should have a written service agreement with each participant. The agreement should cover the types of supports you will provide, the agreed rates, payment terms, cancellation policy, and both parties' responsibilities. A written service agreement protects both you and the participant and is best practice even for unregistered providers.

Insurance Requirements

Unlike employees who are covered by their employer's insurance and workers compensation, sole traders must arrange their own coverage. This is one of the most important (and most commonly overlooked) aspects of operating as a sole trader.

Insurance Type What It Covers Typical Cost Required?
Public liability Claims from third parties for injury or property damage arising from your business activities $300-$600/year Effectively mandatory — most participants and plan managers require it as a condition of engagement. Minimum $10 million cover recommended.
Professional indemnity Claims arising from your professional advice or services — e.g., a participant alleges your support caused harm $200-$500/year Strongly recommended. Some plan managers require it.
Personal accident / income protection Covers your income if you are injured and cannot work. Sole traders are not covered by workers compensation. $500-$2,000/year Not legally required but essential for financial protection. If you are injured at work, you have no workers comp safety net.
Workers Compensation Warning

Sole traders are not covered by workers compensation in most states and territories. If you are injured while providing support — for example, during a manual handling task — you have no automatic entitlement to income replacement or medical expense coverage. Personal accident insurance or income protection insurance is the sole trader's equivalent of workers compensation. Do not operate without it.

NDIS Compliance Obligations

Whether you are registered or unregistered, certain NDIS compliance obligations apply to all workers who deliver NDIS-funded supports.

NDIS Code of Conduct

The NDIS Code of Conduct applies to all NDIS workers regardless of whether they are employed, contracted, or operating as a sole trader. As a sole trader, you are directly subject to the Code — there is no employer between you and the NDIS Commission. A breach of the Code can result in compliance action directly against you, including banning orders that prevent you from providing NDIS supports.

Incident Reporting

If you are a registered provider, you have mandatory incident reporting obligations to the NDIS Commission. If you are unregistered, you are still encouraged to report serious incidents and are obligated to report any conduct that may constitute abuse, neglect, or exploitation of a participant.

Record Keeping

Maintain clear records of all supports provided, including:

Privacy and Confidentiality

You are bound by the Australian Privacy Principles (APPs) under the Privacy Act 1988 if your annual turnover exceeds $3 million, or if you provide health services (which NDIS supports may be classified as). Even below the threshold, best practice is to handle participant information in accordance with the APPs. This includes only collecting information you need, storing it securely, not disclosing it without consent, and allowing participants to access their own records.
