Becoming an NDIS support worker or allied health provider as a sole trader is one of the most flexible ways to build an independent career in disability support, but the paperwork can feel overwhelming if nobody walks you through it step by step.
This guide brings together everything you need to know, from choosing your provider status through to sending your first invoice and keeping your bookkeeping organised.
Think of this as your starting point. Each section explains the next stage of the process and links to more detailed resources where appropriate.
1. Decide Between Registered and Unregistered Provider Status
Before doing anything else, understand the difference between being a registered and an unregistered NDIS provider. Your choice affects who you can work with and how much administration is involved.
Registered providers are audited against the NDIS Practice Standards by the NDIS Quality and Safeguards Commission. Registration allows you to support participants regardless of how their plans are managed, including NDIA-managed (agency-managed) participants, and is mandatory for certain higher-risk support categories.
Unregistered providers don’t complete the formal registration audit. They can work with self-managed and plan-managed participants. Most new sole traders choose this option because it’s quicker, more affordable and involves significantly less paperwork.
Unregistered Provider
- Faster to get started
- Lower setup costs
- Less administration
- Can work with self-managed and plan-managed participants only
Registered Provider
- Requires registration audit
- Ongoing compliance obligations
- Can work with NDIA-managed participants
- Required for certain higher-risk support types
There isn’t a right or wrong choice. Many sole traders begin as unregistered providers and register later once their business grows.
Ask yourself:
Who do I want to work with during my first year?
If most of your clients will be self-managed or plan-managed participants, becoming an unregistered provider is usually the simplest path.
2. Get an ABN as an NDIS Sole Trader
As a sole trader, you and your business are the same legal entity, making setup straightforward.
Before you can invoice participants, plan managers or the NDIA, you’ll need an Australian Business Number (ABN).
Your checklist:
- Apply for a free ABN through the Australian Business Register.
- Decide whether you’ll trade under your own name or register a business name.
- Determine whether you need to register for GST. Registration becomes compulsory once your turnover exceeds the ATO threshold.
- Open a dedicated business bank account to keep income and expenses separate.
Once your ABN is active, set up your invoicing and bookkeeping system immediately.
Starting with an organised system from day one makes tax time much easier than trying to sort months of receipts later.
3. Complete the NDIS Worker Screening Check
Most sole traders delivering NDIS-funded supports need to complete an NDIS Worker Screening Check before working with participants.
What does the screening check include?
The assessment reviews:
- Criminal history
- Workplace misconduct findings
- Other relevant safety information
It is more comprehensive than a standard police check and is specifically designed for NDIS workers.
Possible outcomes
After assessment you’ll receive either:
- Cleared — You can provide NDIS supports covered by the screening requirements.
- Excluded — You cannot undertake those NDIS roles.
Clearances remain valid for a set period before renewal is required. Check your state or territory’s screening unit for current validity periods.
How the application works
Applications are handled by your state or territory screening authority.
Generally you’ll:
- Apply online.
- Verify your identity.
- Pay the applicable fee.
- Wait for your assessment.
Processing times vary depending on where you live.
NDIS Worker Screening Database (NWSD)
Once approved, your clearance appears in the NDIS Worker Screening Database (NWSD).
Participants, plan managers and providers can verify your clearance through this national database.
It’s good practice to periodically check your record, particularly if:
- You move interstate.
- Your personal details change.
- You’re renewing your clearance.
PRODA and portal access
Unregistered providers can still set up identity verification using PRODA (Provider Digital Access).
Unlike registered providers, most unregistered sole traders invoice participants or plan managers directly rather than claiming through the NDIA portal.
4. Get the Right Insurance
Insurance is considered essential for operating as an NDIS sole trader.
Many participants, plan managers and support coordinators will request proof of insurance before engaging your services.
Public Liability Insurance
Public liability insurance covers situations where:
- Someone is injured because of your work.
- You accidentally damage another person’s property.
This is generally considered essential if you provide in-person supports.
Professional Indemnity Insurance
Professional indemnity insurance protects you if someone claims your advice or professional services caused them financial loss or harm.
It is particularly important for allied health professionals but is increasingly expected for support workers as well.
Insurance requirements vary depending on the services you provide, so always check your service agreements and speak with an insurer experienced in the NDIS sector.
5. Set Up a Service Agreement With Each Participant
A service agreement outlines the arrangement between you and your participant.
It protects both parties and provides a written record of what has been agreed.
Your agreement should include:
- Supports you’ll provide
- Frequency of supports
- Rates and applicable NDIS support item numbers
- Travel arrangements
- Cancellation policy
- Start date
- Review date
- How either party can end the agreement
It doesn’t need to be lengthy.
Many sole traders use a simple one or two-page agreement written in plain English.
The important thing is that:
- Both parties understand it.
- Both parties receive a copy.
- It is updated whenever support arrangements change.

6. Send Your First Compliant NDIS Invoice
Once you’ve delivered supports, your invoice needs to include specific information so participants and plan managers can process it correctly.
A compliant invoice should include:
- Your business name
- ABN
- Participant’s name
- NDIS participant number
- Support item number
- Support description
- Dates services were delivered
- Hours or units provided
- Unit price
- Total amount
- GST treatment
The invoicing process varies depending on how your participant’s plan is managed:
Using bookkeeping software with NDIS invoice templates and support catalogue integration can save significant time and reduce errors.
7. Keep On Top of Bookkeeping and GST
Once your business is operating, accurate bookkeeping becomes one of your most important ongoing responsibilities.
This includes:
- Recording income
- Tracking expenses
- Setting aside money for tax
- Reconciling bank transactions
- Managing BAS obligations (if applicable)
Most NDIS supports are GST-free under ATO disability support provisions, provided eligibility requirements are met. Learn more in our NDIS GST Guide for Sole Traders.
However, if you’re registered for GST, you still have reporting obligations.
It’s also worth reviewing your hourly rates regularly to ensure they’re consistent with the latest NDIS Pricing Arrangements and Price Limits. Our NDIS Hourly Rate Calculator makes it easy to calculate compliant rates.
