Special Disability Trusts in Australia: What They Are and How to Set One Up

For parents of children with significant disability, financial planning takes on a dimension that most financial advice doesn't prepare you for. The standard approaches — superannuation, family trusts, direct gifts — interact with Centrelink's means testing in ways that can inadvertently reduce your child's Disability Support Pension or complicate their eligibility for other support payments.

The Special Disability Trust (SDT) is a specific legal structure created under the Social Security Act to address exactly this problem. It allows families to set aside assets for the future care of a person with disability, with significant Centrelink concessions that wouldn't apply to ordinary trust arrangements.

What a Special Disability Trust Is

An SDT is a private trust established for the exclusive benefit of a person with a severe disability. Its sole purpose is to fund that person's reasonable care and accommodation needs — it cannot be used for general family purposes or benefit other family members.

Unlike other private trusts, assets held inside an SDT receive special treatment under Centrelink's means testing rules. This makes it a powerful tool for families who want to protect inherited wealth or accumulated assets without jeopardising the beneficiary's entitlement to the Disability Support Pension or other Centrelink payments.

The Asset Test Concession: How Much Can Be Held

The core financial benefit of an SDT is a significant asset test concession for the beneficiary. As of 2026, assets held in an SDT are exempt from the beneficiary's Centrelink asset test up to approximately $832,750 (this figure is indexed annually — always confirm the current limit with Services Australia).

What this means in practice: if a person with disability receives an inheritance or a family gift placed into an SDT, those assets are not counted against them for purposes of the DSP income and asset tests — up to the limit. Assets above the limit are assessed normally.

Without an SDT, receiving a significant inheritance or gift could push a DSP recipient's assets above the means testing threshold, reducing or eliminating their pension. The SDT structure prevents this.

The Gifting Concession for Parents and Immediate Family

There is a separate, equally significant concession for the family members who contribute to the trust. Normally, Centrelink treats gifts as a deprivation of assets — if a pensioner gives away money, Centrelink may still count those assets against their own means test for up to five years.

The gifting concession for SDTs provides an exemption from this deprivation rule for contributions made to an SDT by parents or immediate family. Combined gifts from parents of up to $500,000 over their lifetime are exempt from the Centrelink deprivation rules. This means parents who are themselves receiving a pension can contribute to an SDT for their child's future care without triggering an asset deprivation assessment.

Who Can Be a Beneficiary

To be eligible as an SDT beneficiary, a person must:

• Have a severe disability — specifically, their condition must be such that they are unlikely to ever be able to work for more than 7 hours per week at minimum wage
• Be an Australian resident
• Not already have an existing SDT

The severe disability threshold is assessed against criteria similar to those used for the Disability Support Pension's impairment tables. A letter from a treating specialist confirming the condition and its impact on work capacity is typically required when establishing the trust.

Importantly, SDT eligibility is not limited to people currently receiving the DSP — though in practice, the same conditions that qualify for DSP generally qualify for SDT eligibility.

What the Trust Can Fund

The SDT must be used exclusively for the beneficiary's reasonable care and accommodation needs. This includes:

• Daily care and support costs (support workers, in-home care, daily activities)
• Accommodation costs (rent, mortgage, modifications to a home for accessibility)
• Medical and health expenses
• Disability-related equipment and assistive technology

There is also a discretionary spending allowance — currently up to approximately $12,500 per year — that can be used for broader purposes including recreation, holidays, and personal development. This allowance recognises that a person's wellbeing extends beyond basic care and accommodation.

The trust cannot be used to benefit anyone other than the beneficiary. If funds are used for ineligible purposes, the SDT loses its concessional status.

Trustee Requirements

An SDT must have at least one of the following as a trustee:

• An immediate family member (parent, sibling, spouse)
• A legal personal representative
• A registered NDIS plan management provider (in some configurations)
• A trust company (professional trustee)

Many families use a family member as trustee — typically a parent initially, then a sibling when the parents are older or no longer able to act. Having a succession plan for the trustee role is important and should be built into the trust deed from the outset.

Trustees have legal fiduciary responsibilities. They must keep records, ensure funds are used only for eligible purposes, and file annual reports with Services Australia. If the trustee is not comfortable with these responsibilities, a professional trustee company can be appointed — at a cost that is borne by the trust.

How to Establish an SDT

Setting up a Special Disability Trust is a legal process that requires a solicitor experienced in disability and elder law. The general steps are:

Step 1: Confirm eligibility Obtain a letter from the beneficiary's treating doctor or specialist confirming that the person has a severe disability meeting the SDT criteria.

Step 2: Engage a solicitor The SDT must be established by a formal trust deed that complies with the legislative requirements under the Social Security Act and associated legislative instruments. Generic online trust documents will not suffice. The solicitor should be experienced in disability trusts specifically — not just general estate planning.

Step 3: Draft and execute the trust deed The deed must specify the beneficiary, the trustee(s), the purpose of the trust, and the terms under which funds can be distributed. It must include the required investment strategy provisions.

Step 4: Register the trust The SDT must be registered with Services Australia. This is what activates the Centrelink concessions — the trust has no special status until registration is confirmed.

Step 5: Fund the trust Assets can be transferred into the trust at establishment or contributed over time. Contributions from parents and immediate family benefit from the gifting concession described above.

When to Establish an SDT: Timing for School Leavers

The SDT is typically established at one of two points: when the beneficiary is approaching adulthood (mid to late secondary school, particularly once the DSP application is being considered), or later when a family member is updating their estate plans and wants to ensure inheritance doesn't affect the beneficiary's pension.

For families with a teenager approaching age 16 and beginning the DSP application process, it is worth consulting a solicitor and financial planner who specialises in disability about whether establishing an SDT now — or planning for one in the estate — is appropriate for your circumstances.

The interaction between the SDT, the NDIS, and the DSP is genuinely complex, and the financial planning decisions made during transition age have effects that last decades. A specialist financial planner with experience in disability financial planning — as distinct from a general financial planner — is worth engaging before making decisions about trust structures, estate planning, or superannuation arrangements for a child with disability.

For the broader transition planning picture — NDIS, Centrelink, employment, and housing — the Australia Post-Secondary Transition Roadmap includes a financial planning chapter covering the SDT, the DSP, and how these interact with NDIS funding in a coordinated way.
