## Key Changes Coming In
Technology and compliance reforms in the **Modernisation of Tax Administration Systems (MTAS) Phase 2** will introduce several critical changes to trust reporting standards starting **1 July 2026**. ([softwaredevelopers.ato.gov.au](https://softwaredevelopers.ato.gov.au/MTAS220260121?utm_source=openai)) Key among them:
- **Mandatory reporting of beneficiary TFNs** for closely held trusts, embedded in trust return lodgment.
- New labels including a **closely held trust indicator**, and a **‘No TFN Provided’** option in the Statement of Distribution.
- Creation of a **pre-fill API** for trust distribution income via the ATO’s API Gateway to simplify data entry and improve accuracy.
## Who’s Impacted
- **Trustees and administrators** of closely held trusts (private trusts with limited beneficiaries), need to ensure beneficiary information is complete and accurate.
- **Tax practitioners and DSPs (Digital Service Providers)** who help prepare and submit trust returns.
- **Software providers** handling trust return forms and Statement of Distribution labels.
## Action Steps to Comply
- **By mid-2026**: Begin collecting beneficiary TFNs for all closely held trusts. If some beneficiaries don’t have TFNs, ensure you can flag that using the ‘No TFN Provided’ label.
- **Update systems & forms**: Liaise with software providers to ensure trust forms include the new labels, distributions, and are compatible with the pre-fill API.
- **Review trust deed & records**: Make sure deeds allow collection of TFNs, and that all distribution documentation is up to date.
## Example Scenario
Imagine *Greenland Family Trust* has five beneficiaries, one of whom has not provided a TFN. Under the new rules:
- GP (the trustee) must collect the missing TFN or flag ‘No TFN Provided’.
- When lodging the trust return after **1 July 2026**, the trust return must include:
- The beneficiary TFNs (or ‘No TFN Provided’ label).
- A closely held trust indicator.
- Correct Statement of Distribution-labelled sections with updated fields.
## Risks of Non-Compliance
- Missing or incorrect TFNs can lead to penalties or withholding obligations.
- Failing to use correct labels or flags may trigger manual reviews or queries by the ATO.
- Software incompatibility may lead to late filing or invalid returns.
## Tips for Smooth Transition
- Start collecting missing TFNs now (even before the official effective date).
- Arrange staff training for trust administration teams on the new return labels and beneficiary information collection.
- Engage with software providers early to ensure trust-preparing systems will comply with pre-fill APIs and embedded fields.
These reforms are part of a larger push to strengthen transparency and trust integrity in the tax system, improve data accuracy, and reduce avoidance risks. Stakeholders who prepare now will avoid headaches when the changes take effect.
