URGENT HELP - SBR - Change of ATO Branch Numbers for STP

Help! Please,

The business that i work for is currently undergoing SBR - Small Business Restructuring.  

As a consequence our ATO Branch number changed from 001 to 004 on the 15 June.

Therefore, all pays processed after the 15 June - need to be allocated to new branch 004.

Unfortunately, I was not made aware of the changes until after 01 July 2025.

Therefore, two pays for 2024-2025 have been entered to the incorrect ATO Branch of 001

I have been advised to delete all of the pays entered to 001.

And re-enter to 004, for all pays processed since the 15 June 2025. 

Which i have done.

To do this - the only thing i did was change the Branch number in the MYOB - STP reporting (as advised by MYOB support).

Unfortunately, they are not showing in ATO Portal at Branch 004 ???

So perhaps i have not done this correctly.

At the moment - my STP 2024-2025 figures are a mess - with two pays missing - and staff annoyed because they cannot lodge their returns. 

Our Accountant has no idea how to fix it and the SBR Practitioners do not know either. 

I called MYOB and i don't think the nice person i spoke to really understood what i needed to do. 

I tried calling ATO and ..."they are experiencing a high demand of calls" and too busy for me just now 🙄

Perhaps - someone has been through this process and can point me in the right direction for correcting this mess.

Thank you,

Jo-Anne
