NDIS Registration for Sole Traders: The Complete 2026 Guide

Many NDIS providers are sole traders - self-employed support workers, allied health practitioners, or behaviour support practitioners delivering under their own business name. Sole trader registration is simpler than company registration, but it has unique requirements. Here's what differs.

Sole Trader vs. Company Registration

As a sole trader, you are the business. There's no separate company entity. Registration is tied to you personally - your name, ABN, tax file number. This simplifies governance (no board meetings, no company minutes required) but it also means your personal liability is higher. As a company, registration is tied to the legal entity - the company is separate from you personally. Registration requires board governance, company minutes, and director oversight. Sole traders skip these. We started Enrichment Care as a company to separate personal and business liability, but many NDIS providers operate successfully as sole traders.

Sole Trader Governance Simplified

You don't need a board or formal governance structure. You need documented decision-making. Auditors ask: How do you make decisions about participant care, safety, and service quality? As a sole trader, answer: You, as the sole decision-maker, review each participant case, consult with relevant professionals (allied health, medical practitioners), and document your decisions. Create a simple decision log or case review note template. Document your thought process. This satisfies governance questions without requiring a formal board.

Worker Screening for Sole Traders

If you employ casual support workers under your sole trader business, standard screening applies - police checks, working with children checks (state-dependent), referee checks. If you're the only worker (you deliver all supports), screening still applies to you - police check required, working with children check if you work with children. State requirements vary. NSW DCJ clearances, QLD Blue Cards, VIC Working with Children Checks. Get your screening sorted before registration.

Participant Agreements and Scope for Sole Traders

You still need written agreements with every participant, even as a sole trader. Your agreement should cover: your name and ABN, services you provide, costs/billing, confidentiality, emergency contacts, complaint process. We use a one-page agreement template. Also specify your scope clearly in your self-assessment and registration application. Are you available 24/7 or only 9am-5pm? Do you work with all participant types or specialise? Sole traders often specialise - 'Allied health practitioner for adults with acquired brain injury' or 'Behaviour support practitioner for children.' Specify your scope clearly.

Financial Management and Invoicing for Sole Traders

As a sole trader, you invoice the NDIA from your business ABN. Your invoices must include your provider number (once registered), invoice number, date, participant details, support hours, hourly rate, and GST (if registered). Keep invoices simple and clear. We recommend using accounting software like Xero with NDIS invoice templates. The NDIA doesn't reimburse until they receive your invoice, so accurate, timely invoicing is critical. Many sole trader providers invoice fortnightly or monthly.

Even as a sole trader, you need professional indemnity insurance (for allied health) or public liability insurance (for all support workers). This protects you if a participant is injured or makes a complaint. Audit Sole trader sole trader insurance is often cheaper than company insurance. Get a quote before registration. We recommend budgeting $500-$1,500 annually for insurance. This is non-negotiable. If you're uninsured and there's an incident, you're personally liable.
