Update 9 January 2026

This issue is fixed in Tax 2025.1 SP1 KB871497729 hotfix (Australia) release.

If you’ve installed 2025 Service Pack 1 (5.4.56/2025.1 SP1), when you lodge individual tax returns, in some cases they may be rejected with validation error CMN.ATO.IITR.730412.

This happens in individual tax returns if:

  • there is a Distribution received from Trust (dit) worksheet (Appendix 1) and

  • any balances reported in:

    • PP Income or

    • Non-PP income less capital gains, foreign income, MIS - Label U (Appendix 2).

This issue is fixed in Tax 2025.1 SP1 KB871497729 hotfix (Australia) release.

Workaround

If the return needs to be lodged urgently

  1. Move the tax return from AE/AO to Tax in MYOB Practice Compliance.

  2. Print a copy of the return to refer to when preparing the return in Tax.

  3. Delete the returns in AE or delete the returns in AO to avoid the returns being accidentally lodged twice.

  4. Lodge the return using Tax in MYOB Practice Compliance.

If the return doesn’t need to be lodged urgently

  1. Wait until we release a hotfix for this issue in mid-January before lodging the return again.

  2. Once you’ve installed the hotfix, move the returns to an in-progress status in AE/AO, complete the returns and then lodge them. You don’t need to make changes to the return.

  3. If the returns are rejected, lodge them again to ensure the data is refreshed.

  4. If the return is still rejected for the same error, contact us.
