We have changed out payroll software mid financial year. Our new software includes details of all previous payroll amounts for the financial year and the new payments that have occured after leaving Reckon. As a result employees have a duplicated income statement from both software systems. Reckon has reported via STP from July to December and the new software has reported from July to present. The ATO tell me I need to delete the amount initially reported via Reckon with an update event. How do I do this?
