No, a family trust does not automatically have an ABN. An ABN is only required if the trust is carrying on an enterprise under Australian law, such as running a business, leasing property on a commercial scale, or engaging in large-scale trading activities. Trusts that only hold passive investments, like shares or a single rental property, generally need only a Tax File Number (TFN) to meet their tax obligations.
When Does a Family Trust Need to Register for an ABN?
A family trust must register for an ABN only when it is carrying on an enterprise in Australia. Under the A New Tax System (Australian Business Number) Act 1999 (Cth), “enterprise” typically includes:
- Operating a business (e.g., trading, consulting, e-commerce, development projects).
- Leasing property on a commercial basis (e.g., multiple properties or activities with business hallmarks such as advertising, systems, and profit intent).
- Regular trading in investments where activity, scale, and systems resemble a business.
- Providing services to related entities for consideration (management fees, IP licences).
Registration is not usually required where the trust merely holds passive investments (e.g., a long-term share portfolio or a single residential rental with minimal activity). If the trust is required to register for GST (turnover at or above the GST threshold from taxable supplies), an ABN is needed first.
What Are the Benefits of a Family Trust Having an ABN?
Holding an ABN offers practical and legal benefits:
- Compliance with the ATO: Enables the trust to register for Goods and Services Tax (GST) where turnover exceeds the statutory threshold.
- Avoidance of withholding: Prevents other businesses from withholding tax at the top marginal rate when payments are made to the trust.
- Legitimacy in transactions: Confirms to banks, suppliers, and regulators that the trust is properly established and registered.
- Integration with tax obligations: Links with the trust’s Tax File Number (TFN) to streamline tax administration.
Family Trust ABN vs TFN for Tax Purposes
A family trust’s Tax File Number (TFN) is mandatory for tax return lodgement and reporting distributions to beneficiaries. An ABN, on the other hand, is only required if the trust is carrying on an enterprise. Both identifiers serve distinct purposes: the TFN ensures compliance with income tax reporting, while the ABN governs the trust’s business and GST obligations.
ATO Guidelines for Family Trust ABN Registration
The Australian Taxation Office (ATO) requires trustees to provide:
- A copy of the executed trust deed.
- Trustee details, including corporate registration where relevant.
- A declaration of the activities constituting the trust’s enterprise.
Once approved, the ABN is recorded on the Australian Business Register and linked to the trust’s TFN for all future dealings.
Family Trust ABN Requirements for Passive Income
Trusts deriving income solely from passive investments—such as dividends, interest, or one residential rental property—generally do not require an ABN. However, if the scale of activity indicates the carrying on of an enterprise (e.g., regular property development, large-scale leasing, or repeated commercial transactions), the ATO may classify the trust as a business and require ABN registration.
Consequences of a Family Trust Operating Without a Required ABN
If a trust carries on an enterprise without an ABN, the consequences include:
- Withholding obligations: Payers may be required to withhold tax at the top marginal rate.
- Penalties: The ATO may impose administrative penalties for non-compliance.
- Breach of trustee duties: Trustees have fiduciary obligations to comply with law. Failing to obtain an ABN when required may expose trustees to personal liability. In such cases, understanding find a good family law lawyer becomes essential, as professional guidance can help trustees manage risks and ensure compliance
Does a Discretionary Trust Need an ABN?
Not by default. A discretionary (family) trust needs an ABN only if it conducts an enterprise. If the trust’s activities are passive—for example, receiving franked dividends, bank interest, or rent from a single residential property without business indicators—a TFN is sufficient for tax reporting.
A discretionary trust should obtain an ABN where it:
- Runs a business or professional practice,
- Undertakes commercial property leasing or development,
- Charges for services (even to related entities), or
- Meets the GST registration threshold through taxable supplies.
Where the line between “passive investment” and “enterprise” is unclear, obtain written advice; misclassifying activity can lead to back-dated ABN/GST obligations, penalties, and interest.
Criteria for a Family Trust to Be Considered a Business for ABN Purposes
The ATO and the courts assess several indicia, including:
- The scale and repetition of activities.
- Whether activities are conducted in a commercial manner.
- Intention and expectation of profit.
- Level of organisation and record-keeping.
If these indicia are satisfied, the trust is considered to be carrying on a business and ABN registration becomes mandatory.
How to Apply for an ABN for a New Family Trust
Trustees must apply through the Australian Business Register, supported by:
- The executed trust deed.
- Identification details for the trustee(s).
- A description of the business activities.
Approval is often immediate, but in some cases the ATO may request additional verification.
Can a Family Trust Operate Without an ABN if Not Conducting a Business?
Yes. A family trust that only holds passive assets can operate lawfully without an ABN. In such cases, only a TFN is required to meet tax obligations.
What Activities Make a Family Trust Eligible for an ABN?
Activities that typically require an ABN include:
- Running a trading or professional business.
- Leasing multiple commercial or residential properties.
- Large-scale property development.
- Farming or agricultural operations undertaken commercially.
