Hi rose68,

Thanks for reaching out to us! If you're trying to zero out the STP amounts previously lodged with the ATO, you can create an earnings reset event. 

Here's how: 

1. Go to Employees tab.
2. Select Reports and then select Single Touch Payroll.
3. Select the arrow dropdown icon next to Create Update Event, then select Create Earnings Reset Event.
4. Read the information box that explains the purpose of an earnings reset event, then select Continue.
5. Select the Financial Year, employing entity and, if applicable, the specific employees you wish to create a reset event for, then select Create.
6. The Earnings Reset Event will appear, with all earnings set to $0. This is what will be reported to the ATO once lodged.
7. Select Lodge with ATO.

However, if you're trying to zero out the opening balances of your employees you may need to create an ad hoc pay run. You can't enter negative figures when you enter amounts in Opening Balances section. 

Here's how to create an ad hoc pay run: 

1. Go to Employees tab.
2. Select New Pay Run. 
3. Enter pay run details and tick on Manually add employees to this pay run. 
4. Select Create.
5. Add employees. Once you've added them, click on the employee name to expand details.
6. From there, you can enter opening balances in negative figures.
7. Select Save and then Finalise pay run once you've confirmed all details are correct.
