Modernisation of Trust Administration Systems (MTAS) working group

The Modernisation of Trust Administration Systems (MTAS) project is an ATO wide strategy to improve the quality, accuracy and integrity of annual income tax return information reported by trustees and beneficiaries.

The MTAS project will deliver improvements to the:

  • lodgment experience for trustees and beneficiaries and provide greater support to meet their reporting obligations
  • administration and processing of trust reporting obligations
  • ATO’s data-driven decision-making process including those which inform compliance and assurance activities.

The working group will discuss implementation of the funded changes the ATO will make in Tax Time 2024, as well as consult on future changes to trust and beneficiary reporting.


The ATO consultation framework underpins our consultation framework arrangements.
