Hi lisa68
These issues are notoriously difficult to fix. MYOB's Payroll Reporting Centre is very 'inflexible'.
The best advice I can give you is if you have not yet processed payroll in July 2023 - don't! Not until this issue is solved. Processing pay in July makes fixing BMD IS issues in 2023 impossible using MYOB.
You can't set your own BMS ID - this is set by MYOB and can only be viewed in the ATO portal or on the final employee's income statement. This is different to the SSID which is shown under ATO settings in the Payroll Reporting Centre.
The Payroll Reporting Centre will not normally show reports lodged by both Essentials and AccountRight. MYOB staff might be able to fix this for you.
If you are using Phase 2, removing termination details for employee who left in 2022/23 and then sending an Update Event should include ALL employees and correct all YTD as per the MYOB file. You could then re-enter the termination details and Finalise all employees if the figures are correct.
If the YTD details from the Essentials period were transferred to AccountRight, this would have caused duplication. The ATO treats each BMS ID as a separate payroll system. You would need to notify the ATO of the Previous BMS ID, this will allow the ATO to remove the original Essentials income statements.
With MYOB, this can only be done when 'migrating' to Phase 2, or by setting up for Phase 2 again. However due to MYOB's inflexible design, the Previous BMS ID will be reported for the current payroll year as in MYOB, which will be 2024 if you have processed pay in July. The ATO will reject this notification as it needs to be sent for the 2023 year.
If the Essentials YTD were not transferred to AccountRight, then is is just a case of working out how to Finalise the Essentials payroll. MYOB may allow you to still access this. If not, it will need to be finalised using different software such as STP Creator. This software is designed to be more flexible than MYOB as far as STP reporting goes, and can be handle fixing these sort of issues.
You have a complicated issue to deal with and might need to get competent guidance. If competent MYOB staff cannot help you, I can put you in contact with someone experienced in this very thing. It would not be a free service, though it might save some stress.
