Trusts Will Need TFNs for All Beneficiaries: Preparing for MTAS Phase 2 Changes
From 1 July 2026, closely held trusts must include the Tax File Number (TFN) of every beneficiary in their trust returns, increasing reporting obligations and compliance risks.

## Overview
Australia’s **Modernisation of Tax Administration Systems (MTAS) Phase 2** is introducing significant changes to how trusts, especially closely held ones, report distributions and beneficiary information. These changes will take effect from **1 July 2026**, and trustees need to prepare now to meet the new **dedicated reporting standards and obligations**. ([softwaredevelopers.ato.gov.au](https://softwaredevelopers.ato.gov.au/MTAS220260121?utm_source=openai))
## Key Changes
- **Mandatory TFN reporting**: Closely held trusts will be required to include the TFN of each beneficiary in their trust return lodgment. ([softwaredevelopers.ato.gov.au](https://softwaredevelopers.ato.gov.au/MTAS220260121?utm_source=openai))
- **New form labels**: Trust returns will include a “closely held trust indicator” and a “No TFN Provided” option in the Statement of Distribution. ([softwaredevelopers.ato.gov.au](https://softwaredevelopers.ato.gov.au/MTAS220260121?utm_source=openai))
- **Pre-fill API expansions**: A non-individual pre-fill API via the ATO API Gateway will be introduced, initially for trust distribution income, to improve accuracy and ease reporting. ([softwaredevelopers.ato.gov.au](https://softwaredevelopers.ato.gov.au/MTAS220260121?utm_source=openai))
## Who Is Affected
These changes mainly impact trustees of closely held trusts (trusts where the number of beneficiaries is limited, and often family or similar structures). Beneficiaries must ensure they have a TFN and make it available to trustees.
## Compliance Implications
- **Penalties risk**: Failing to supply beneficiary TFNs where required may lead to administrative or tax penalties.
- **Privacy considerations**: Trustees will need proper handling of TFNs and consider privacy/consent issues.
- **Data responsibility**: Correct reporting requires updated record-keeping systems and possibly software changes to capture required data. The pre-fill API may help reduce manual errors.
## Actionable Steps for Trustees
1. **Audit beneficiary list**: Confirm who is a beneficiary and ensure each has a valid TFN well before 1 July 2026.
2. **Review trust deed**: Ensure that the trust deed allows collection and disclosure of TFNs as required.
3. **Upgrade reporting systems**: If using software or engaging an accountant or trustee service, ensure tools support new labels and TFN reporting functions.
4. **Communicate with beneficiaries**: Provide clear notices to beneficiaries to submit TFNs ahead of the deadline.
5. **Use pre-fill API where possible**: Work with software providers to use the ATO’s new API services for trust distribution income to ensure accurate data.
## Example Scenario
Trustee of a small family trust has three beneficiaries. Only one has provided a TFN so far. Under the new rules, when lodging the trust return for the year ending 30 June 2026 (lodged in Tax Time 2027), the trustee must report:
- Beneficiary 1: Name + TFN
- Beneficiary 2: Name + "No TFN Provided" label if TFN not given
- Beneficiary 3: Name + TFN (if available)
Also, the “closely held trust indicator” field will need to be selected.
## Conclusion
The MTAS Phase 2 changes represent a **significant shift in trust reporting** in Australia, geared toward **greater transparency, integrity, and data accuracy**. Trustees and their advisors should begin planning immediately to adapt to these obligations. Missing TFNs or misreporting could now have material consequences.
