NDIS Provider Business Structure: Sole Trader vs Company vs Partnership

Business Structure Options at a Glance

Every NDIS provider must operate under a recognised Australian business structure. Your choice determines not just how you pay tax, but how the NDIS Commission assesses your suitability, who your key personnel are, and how much personal risk you carry.

Sole Trader: Simplest Entry Point

A sole trader is the simplest business structure in Australia. You trade under your own name (or a registered business name), use your own TFN for tax purposes, and control all business decisions. There is no legal separation between you and your business.

Advantages for NDIS providers

• Cheapest to set up — free ABN registration, no ASIC fees, no company constitution
• Simplest compliance — no annual ASIC returns, no director duties, no separate company tax return
• Full control — you make all decisions without consulting a board or co-directors
• Easiest registration — only one key person (you) needs to pass the NDIS suitability assessment
• Tax offset eligibility — small business income tax offset can reduce your tax bill

Disadvantages for NDIS providers

• Unlimited personal liability — this is the critical issue. If a participant is injured and the claim exceeds your insurance, your personal home, savings, and assets are at risk
• Higher tax at scale — once your profit exceeds approximately $90,000, you pay a higher marginal rate than the 25% company rate
• No continuity — if you become ill, incapacitated, or want to sell the business, the sole trader structure dies with you
• Harder to scale — investors, banks, and partners generally prefer dealing with companies
• Governance concerns — auditors may question the robustness of your governance framework when one person controls everything

When a sole trader structure works

A sole trader structure is appropriate when you are:

• A solo practitioner (support coordinator, plan manager) in a lower-risk registration group
• Starting out and testing the market before committing to a company structure
• Delivering services that do not involve personal care, medication, or high-intensity support
• Operating with no employees (using only your own labour)

Company (Pty Ltd): The Recommended Structure for SIL Providers

A proprietary limited company (Pty Ltd) is a separate legal entity from its owners (shareholders) and operators (directors). This separation creates the limited liability protection that makes it the preferred structure for NDIS providers delivering high-risk supports.

Advantages for NDIS providers

• Limited liability — your personal assets are protected. If the company is sued, only company assets are at risk (with limited exceptions for director misconduct)
• Lower tax rate — 25% company tax rate for base rate entities (turnover under $50 million), compared to personal marginal rates of up to 45%
• Professional credibility — participants, families, support coordinators, and the NDIS Commission view companies as more established and professional
• Scalability — easier to add shareholders, raise capital, hire staff, and eventually sell the business
• Governance structure — the director/shareholder/secretary structure naturally maps to the NDIS Commission's expectations of a governing body
• Continuity — the company continues to exist regardless of changes to directors or shareholders

Disadvantages for NDIS providers

• Higher setup cost — ASIC registration ($538 for a standard company), plus accountant fees for constitution and initial setup
• Annual ASIC fees — approximately $310 per year for the annual review
• More complex tax — separate company tax return, potentially franking credits, and more complex accounting
• Director duties — directors have legal duties under the Corporations Act 2001 (duty of care, duty to act in good faith, duty to prevent insolvent trading)
• More key personnel — every director must pass the NDIS Commission suitability assessment

Company structure for a small SIL provider

A typical small SIL provider company structure looks like this:

• 1–2 directors (who are also the shareholders and operators)
• 1 company secretary (can be a director)
• ABN and TFN registered to the company
• Registered office at the business address or accountant's office

This is the structure we recommend for any provider delivering SIL, personal care, high-intensity supports, or employing more than 2–3 staff. The SIL Rescue Kit includes a governance framework document and organisational chart template designed for this structure.

Partnership: Why Most Advisors Say Avoid It

A partnership is where two or more people carry on a business together with a view to profit. Partnerships can be general (all partners share management and liability) or limited (some partners contribute capital but do not manage).

Why partnerships are problematic for NDIS providers

The critical issue with partnerships is joint and several liability. Under partnership law (Partnership Act in each state/territory), each partner is personally liable for:

• All debts of the partnership
• All actions of the other partners taken in the course of business
• Any claims arising from the partnership's NDIS services

This means if your partner makes a medication error that injures a participant, you are personally liable for the resulting claim — even if you were not present, not involved, and did not know about it. In a high-risk sector like disability services, this is an unacceptable level of exposure.

When a partnership might work

The only scenario where a partnership might be acceptable is for very low-risk, professional service registration groups (such as two support coordinators sharing an office) where both partners are actively involved in every aspect of the business and the risk of participant injury claims is minimal. Even then, a company is usually the better choice.

Not-for-Profit and Charity Structures

Many NDIS providers operate as not-for-profit (NFP) organisations. Common NFP structures include:

• Incorporated association — registered under state/territory associations legislation (e.g., Associations Incorporation Reform Act 2012 in Victoria)
• Company limited by guarantee (CLG) — registered under the Corporations Act 2001 with ASIC; members guarantee a small amount (usually $10–$100) rather than holding shares
• Indigenous corporation — registered under the Corporations (Aboriginal and Torres Strait Islander) Act 2006 with ORIC

Advantages for NDIS providers

• Tax exemptions — registered charities are exempt from income tax; DGR (deductible gift recipient) status allows tax-deductible donations
• Grant eligibility — many government and philanthropic grants are only available to NFP or charitable organisations
• Community trust — participants and families may perceive NFPs as more mission-driven than for-profit providers
• Limited liability — incorporated associations and CLGs provide limited liability for members and officeholders

Disadvantages for NDIS providers

• More complex governance — boards, constitutions, member meetings, and reporting obligations under both associations/corporations legislation and ACNC (Australian Charities and Not-for-profits Commission)
• No profit distribution — profits cannot be distributed to members or directors; all surplus must be reinvested in the organisation's purpose
• Board recruitment — finding and retaining skilled board members can be challenging for small NFPs
• More key personnel — all board members are key personnel for NDIS registration purposes, requiring suitability assessments for each

Key Personnel Implications by Structure

Under Section 73F of the NDIS Act 2013, the NDIS Commission must be satisfied that a provider's key personnel are suitable to be involved in the provision of NDIS supports and services. Key personnel include members of the provider's governing body, executive officers, and any person with significant operational authority.

Suitability assessment details

Each key person must complete a statutory declaration covering:

• Criminal history (including spent convictions in some jurisdictions)
• History of personal insolvency or involvement with insolvent companies
• Any previous NDIS provider banning orders or compliance actions
• Any conditions, undertakings, or sanctions under state/territory disability services legislation
• Any relevant professional registration conditions or restrictions

The Commission may refuse registration if any key person has a relevant criminal history, a pattern of financial irresponsibility, or a history of non-compliance with disability services legislation.

Transitioning Between Structures

Many providers start as sole traders and later transition to a company structure as they grow. This is common, but it is not a simple name change — it requires careful planning.

Sole trader to company transition

1. Establish the company — register with ASIC, obtain a new ABN and TFN for the company
2. Notify the NDIS Commission — your sole trader registration cannot transfer to the company. The company must apply for registration as a new provider entity
3. Undergo a new audit — the new company entity will need its own certification audit
4. Transfer insurance — your sole trader insurance policies cannot simply be renamed. You need new policies in the company's name
5. Transfer service agreements — all participant service agreements need to be re-signed with the new company entity
6. Notify plan managers and the NDIA — invoicing and service bookings must be updated to the new ABN
7. Wind down sole trader registration — once the company registration is active, surrender your sole trader registration

Tax implications of transitioning

When you transfer a business from a sole trader to a company, there are potential capital gains tax, GST, and stamp duty implications. Some small business rollover concessions may apply under Division 122 and Division 152 of the Income Tax Assessment Act 1997. Engage a tax accountant who understands small business restructures before making the change.
