NDIS providers must get three things right: GST (many NDIS supports are GST-free, but not all), PAYG withholding (required once you employ staff), and correctly classifying workers as employees or contractors. Misclassifying an employee as a contractor is one of the most expensive mistakes in the sector, creating back-paid super, PAYG and penalties.
What NDIS Providers and Support Workers Need to Know (Melbourne Guide)
If you operate within the disability services space, whether as a support worker, sole trader, company or growing provider, understanding your tax obligations is critical.
Many NDIS businesses are unsure about:
- GST registration
- Whether invoices should include GST
- How PAYG withholding (PAYGW) works
- Whether workers should be treated as contractors or employees
- How to lodge their tax return correctly
As experienced accountants in Melbourne, we regularly assist providers with these issues.
This guide explains these concepts in clear, practical terms so you know what is required and when.
1. NDIS and GST – Are Your Services Taxable?
One of the most common questions we receive as tax accountants in Melbourne is: “Do I need to charge GST on NDIS services?”
Many NDIS-funded supports are GST-free, but not all income earned in the disability sector is automatically GST-free.
Under ATO rules, disability supports are generally GST-free when:
- The service is provided to an NDIS participant
- The support is included in the participant’s NDIS plan
- There is a written agreement in place
- The service qualifies as a GST-free disability support under legislation
If these conditions are met, you do not charge GST.
However, GST may apply if:
- You provide services outside of an NDIS plan
- You deliver services that do not qualify as GST-free supports
- You provide other taxable services (for example training, consulting, or non-NDIS services)
Incorrect GST treatment can create serious ATO compliance issues. A qualified chartered accountant or CPA accountant with experience can help you determine the correct position.

2. When Do You Need to Register for GST?
You must register for GST when your annual turnover reaches $75,000 or more.
This applies whether you are:
- A sole trader support worker
- A company
- A partnership
- A trust
Turnover refers to your total business income before expenses.
Important: Even if your NDIS services are GST-free, they still count towards the $75,000 GST registration threshold.
This means many NDIS providers in Melbourne must register for GST even though they may not charge GST on most invoices.
Voluntary GST registration is also possible if turnover is below $75,000, but this should only be done after speaking with a registered tax agent or chartered tax advisor.
3. Should Your Invoices Include GST?
Whether GST applies depends on:
- Are you registered for GST?
- Are your services taxable or GST-free?
If you are registered and your services are GST-free, your invoice should: state the supply is GST-free and show GST as $0.
If your services are taxable and you are registered: you must charge 10% GST and your invoice must meet ATO tax invoice requirements.
If you are not registered for GST, you cannot charge GST.
4. PAYG Withholding (PAYGW) – When Does It Apply?
PAYG withholding applies when you have employees. If you hire staff in your NDIS business, you must register for PAYG withholding, withhold tax from wages, report through Single Touch Payroll, pay withheld amounts to the ATO, and pay superannuation.
PAYGW does not apply to genuine contractors. However, incorrectly classifying workers as contractors can result in unpaid superannuation, backdated PAYG obligations, ATO penalties, and payroll tax exposure.
5. Contractor vs Employee – Why It Matters for NDIS Providers
The difference between contractor and employee is based on the working relationship — not what you call them.
An employee generally works under your direction and control, uses your systems and processes, cannot delegate work, is paid hourly wages, and receives superannuation.
A contractor generally operates their own business, can delegate work, controls how and when work is performed, has their own insurance, and invoices for services.
The ATO and Fair Work actively review worker classification in the NDIS sector. A chartered accountant or CPA accountant experienced in NDIS businesses can assess your structure and reduce compliance risk.
Why Professional Advice Is Important
NDIS providers operate in a highly regulated environment where tax, payroll and compliance obligations intersect with ATO regulations, Fair Work legislation, NDIS Commission requirements, and superannuation laws. Getting it wrong can be costly.
If you operate in the NDIS sector and are unsure about your current structure, speak with a qualified tax accountant in Melbourne who understands the sector.

NDIS providers must register for GST if their annual business turnover reaches $75,000 or more. This threshold applies even if most or all of their NDIS services are GST-free. GST-free income still counts toward the registration threshold. If turnover is below $75,000, registration is optional, but it is important to seek professional advice before registering voluntarily to understand the reporting and compliance obligations involved.
2. Should I charge GST on my NDIS invoices?
Many NDIS-funded supports are GST-free if they are provided to an NDIS participant, are included in the participant’s approved plan, and meet the ATO requirements for GST-free disability services. If your services qualify as GST-free and you are registered for GST, your invoice should show that GST is $0 and clearly state that the supply is GST-free. If you provide taxable services and are registered for GST, you must charge 10% GST and issue a compliant tax invoice. If you are not registered for GST, you cannot charge GST.
3. Do I need to register for PAYG withholding in my NDIS business?
You must register for PAYG withholding if you employ staff and pay them wages. This means you are required to withhold tax from their pay, report through Single Touch Payroll, pay superannuation, and meet Fair Work obligations. PAYG withholding generally does not apply to genuine independent contractors, but the working relationship must meet ATO criteria. Misclassifying employees as contractors can result in penalties and back payments.
4. How do I know if my support worker is a contractor or an employee?
The difference depends on the actual working arrangement, not what the contract says. An employee typically works under your direction, cannot delegate their work, and is paid wages with superannuation and PAYG tax withheld. A contractor usually runs their own business, invoices for services, controls how the work is performed, and may delegate tasks. Because the NDIS sector is closely monitored, it is important to assess these arrangements carefully to ensure compliance with ATO and Fair Work rules.

Frequently Asked Questions
Are NDIS services GST-free?
Many NDIS supports are GST-free when the participant has an NDIS plan, the support is listed in the relevant NDIS rules, and there is a written agreement to provide it. Not every support qualifies, so each service you provide must be checked against the GST-free conditions.
When does an NDIS business need to register for GST?
You must register for GST once your turnover reaches $75,000, even if most of your supplies are GST-free. Registering lets you claim GST credits on business purchases while still treating eligible NDIS supports as GST-free to participants.
What is the difference between an employee and a contractor?
It depends on the whole working relationship, not just the label in a contract: the level of control, the ability to delegate, who bears financial risk, who provides tools, and whether the worker genuinely runs their own business. Getting this wrong creates PAYG, super and workers compensation liabilities.
Do I have to pay super to NDIS contractors?
Often yes. If a contractor is paid mainly for their labour, they can be deemed an employee for super purposes even with an ABN, which means the super guarantee applies. Review each arrangement carefully rather than assuming an ABN removes the obligation.
