Trust tax debt: who actually owes it — trustee, directors or beneficiaries?

Who actually owes a trust's tax debt

Thousands of Australian businesses trade through a discretionary or family trust, often set up years ago on advice that it would "protect assets". Then a tax debt appears in the trust's activity statements and everyone asks the same question: who does the ATO actually chase?

The legal answer is clean: a trust is a relationship, not an entity. It cannot owe a debt. Every debt "of the trust" — the BAS debt, the PAYG withholding, the super guarantee charge — is legally a debt of the trustee, the person or company that carries on the business on the trust's behalf. The trust's ABN and GST registration sit with the trustee "as trustee for" the trust, and the ATO's assessments and demands are directed at the trustee.

So the first question in any trust debt problem is not "what does the deed say" — it's "who is the trustee, and is it a human or a company?" Everything flows from that.

The trustee's right of indemnity — and its limits

A trustee who properly incurs a debt running the trust's business is entitled to pay it from trust assets, or be reimbursed if they've paid it personally. This "right of indemnity" is the buffer between the trustee and personal loss — and creditors, including the ATO, can effectively stand in the trustee's shoes and reach trust assets through it.

The buffer works only as well as what sits behind it:

• If trust assets cover the debt, the trustee is protected in practice — the debt is paid from the trust and nobody's personal assets are touched.
• If trust assets fall short, the indemnity is worth only what the trust holds. The shortfall doesn't vanish — it rests with the trustee personally.
• If the trustee acted in breach of trust or outside its powers, the indemnity can be lost for those debts — liability without the buffer.

Individual trustees: fully personally exposed

If you are (or were) an individual trustee of a trading trust, the trust's tax debts are your personal debts, enforceable against your personal assets — home included — to the extent trust assets can't cover them. The ATO can use every tool it uses on a sole trader: garnishee notices, offsetting your refunds, court judgment, and ultimately bankruptcy. Retiring as trustee doesn't erase liability for debts from your time in the role. An individual trustee facing an unpayable trust debt is, in substance, in the same position as a sole trader with ATO debt — including, at the far end, the same options up to bankruptcy.

The corporate trustee wrinkle: enter the DPN

Most advisers use a company as trustee precisely to contain this liability — the debt sits in the corporate trustee, which typically owns nothing in its own right beyond its indemnity from trust assets. If the trust fails, the company fails, and in theory the humans walk away.

The theory has a large hole in it. The corporate trustee is still a company with directors, PAYG withholding, net GST and super obligations — which means the director penalty regime applies in full. The ATO can issue DPNs to the directors of the trustee company and make them personally liable for the trust business's unpaid PAYGW, GST and SGC, exactly as if the company traded in its own right. All the usual rules follow: 21 days from the date of the notice, remission through payment or an insolvency appointment for non-lockdown amounts, and lockdown treatment — payment only — where BAS ran more than 3 months late or SGC statements were lodged late.

Beneficiaries: generally safe — with two footnotes

The good news in most family trust collapses: beneficiaries are generally not liable for the trust's trading debts. Being named in a discretionary trust deed, or having received distributions in past years, doesn't make you a debtor of the ATO for the trust business's GST or PAYGW. Creditors' claims run against the trustee and, through the indemnity, against trust assets — not against beneficiaries' personal wealth.

Two footnotes keep that honest:

• Your own tax on trust distributions is your own debt. Beneficiaries pay income tax on trust income distributed to them. If distributions were made to you (even on paper, unpaid) and the tax wasn't covered, that assessment is yours — a personal income tax debt, separate from the trust's trading debts.
• Rare indemnity cases. In unusual structures — essentially a single adult beneficiary absolutely entitled to the trust who directed the show — courts have made beneficiaries indemnify the trustee. It almost never applies to an ordinary discretionary family trust, but "almost never" is not "never", so oddly-shaped trusts deserve advice.

If the trust's debt can't be paid

The options track the trustee's identity. A corporate trustee with a viable business may fit small business restructuring (liabilities under $1m, lodgments up to date, super paid) — which also remits non-lockdown DPNs if the practitioner is appointed within the 21-day window. A non-viable corporate trustee generally ends in liquidation, with the directors' residual exposure defined by the DPN rules. An individual trustee negotiates, pays, or looks at personal insolvency. And in every version, a payment plan can buy time but does not remit director penalties. If you're not sure where your structure lands, start here.
