Treasury’s consultation on modernising tax administration for trust and investment income reporting closed on 1 February 2026.

A key proposal is a new annual TFN withholding reporting cycle for trustees of closely held trusts and interposed entities, with a proposed start date of 1 July 2026.

What is being proposed

The consultation materials outline a modernised reporting model intended to improve data quality and reduce reconciliation issues across trust reporting.

For many trustees and advisers, the practical headline is that TFN withholding reporting for certain trust structures would move into a clearer annual cycle aligned with broader modernisation reforms.

ATO implementation signal

ATO’s Modernisation of Tax Administration Systems (MTAS) updates indicate this trust TFN withholding stream is part of MTAS Phase 2, with system messaging updates already being rolled out (including new PLS interaction messages from 23 February 2026).

That does not make every proposal law yet, but it is a strong operational signal that implementation planning is active.

Why this matters for trustees and advisers

If enacted, the changes would affect:

  • annual trust reporting workflows
  • onboarding controls for beneficiary and TFN withholding data
  • software and lodgment process settings
  • year-end review timelines for closely held trust groups

Practical steps now

Before 1 July 2026, trustees and tax teams should:

  • map current TFN withholding processes and responsible owners
  • test data capture quality for beneficiary details and withholding events
  • confirm software readiness with providers for MTAS-related changes
  • monitor Treasury outcomes and final legislation timing

What to watch next

  • Government response to consultation feedback
  • draft or introduced legislation for trust reporting reforms
  • ATO technical guidance and product readiness notices
