Thanks for posting in the Community! If you are using Single Touch Payroll (STP) and wanted to lodge nil figures to the ATO, you can do so via an Earnings Reset Event:
Navigate to the Employees section.
Select the Reports tab and then select Single Touch Payroll.
Select the arrow drop-down icon next to Create Update Event, then select Create Earnings Reset Event.
This will create a nil lodgement that you can send to the ATO.
