Hi mistyben,
You can transfer the BMS ID within the MYOB software. In the STP/Payroll Reporting Center, go to ATO settings, edit STP Business details, and on the prompt asking if you reported from a different payroll software, select 'yes'. Then you'll then be prompted to enter the previous BMS ID, which you can obtain from the ATO portal. Copy it, paste it into MYOB, and complete the setup. You should zero out the amount on the old payroll software and then finalize it with zero amounts, ensuring only the totals from the MYOB payroll remain.
I also hope that someone on the Community Forum here will share their ideas on this process.
Additionally, you can reach out to our support team for further assistance via Live Chat through our virtual assistant at MYOB Support or by submitting a support case via MYOB Account.
I hope this helps!
Regards,
Earl
