Do NDIS providers pay GST? Most registered NDIS providers must register for GST once turnover reaches $75,000, but the supports they deliver to participants are usually GST-free, so the provider charges no GST while still claiming GST credits on business purchases. A supply is GST-free only where the participant has an NDIS plan, the support is specified in that plan, there is a written agreement, and the support is covered by a table in the GST-free Supply (NDIS Supports) Determination 2021. Specialist Disability Accommodation sits in Table 1 of that Determination. This guide covers GST, SDA, PAYG withholding and the contractor rules for NDIS provider businesses.
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.
Therapy supports are the area we see go wrong most often. If your business delivers music therapy, art therapy, counselling or exercise physiology, read our detailed guide to GST on NDIS therapy services, because most therapy delivered in a clinic or community setting fails the fourth GST-free condition.
For NDIS and care businesses
Contractor or employee? Get the structure and compliance right
Misclassifying workers or mishandling GST and PAYG withholding is expensive for NDIS providers. We set up the right structure and systems so your business stays compliant and protected as it grows.

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.
GST and Specialist Disability Accommodation (SDA)
SDA is one of the most misunderstood areas of NDIS GST, because accommodation normally sits outside the GST-free rules. Residential rent is input taxed, which would ordinarily mean no GST charged and no credits claimed on related costs.
SDA is treated differently. Specialist disability accommodation, and accommodation or tenancy assistance, are covered by Table 1 of the A New Tax System (Goods and Services Tax) (GST-free Supply—National Disability Insurance Scheme Supports) Determination 2021. That means an SDA supply can be GST-free, rather than input taxed, provided the same four conditions are met: the participant has an NDIS plan, the support is specified in the statement of supports in that plan, there is a written agreement to provide it, and it is covered by one of the tables in the Determination.
The distinction matters commercially. A GST-free supply still allows you to claim GST credits on construction, maintenance and other costs. An input taxed supply does not. For an SDA investor or provider building or acquiring dwellings, that difference can run to tens of thousands of dollars on a single property, and it turns on documentation that is usually settled long before the first participant moves in.
The written agreement does not have to be with the participant personally. It can be with someone managing the plan and funding, including the NDIA, a registered plan management provider, or a guardian or relative. See the ATO guidance on GST and the National Disability Insurance Scheme.
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.

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.
