How Do I Process Single Touch Payroll When Moving From Another Payroll Program?

The ATO offers several methods to switch payroll providers when it comes to Single Touch Payroll, as explained on the ATO website.

We recommend the Zeroing Out Method (if your previous software allows it):

1. Before you transfer the YTD (Year-to-Date) amounts to Lightning Payroll, send an Update Event from your previous software that shows all the YTD amounts for your employees as zero.
2. Transfer your employees' YTD amounts into Lightning Payroll via the Pays screen (recommended for accuracy), or by making a YTD adjustment: open the employee record, select the Year to Date tab, then click Adjust YTD Totals. See How Do I Enter Existing Year-to-Date Figures? for a full comparison of methods.
3. Start sending STP regularly through Lightning Payroll.

This will notify the ATO that you have made these changes.
