I paid an employee some travel reimbursement using an expense category, Now I need to take it back off them, how do I enter a negative expense amount?

Hi dee8,

While employee expense reimbursements are not able to be entered as a negative to 'reverse' them, in this instance you would amend the existing payrun showing the expense reimbursement:

1. Go to the Employees tab, then the Pay Runs tab and click on the payrun to open it.
2. Select the Pay Run Actions menu, then Unlock. Enter a note if required, then Unlock.
3. Click the employee's name to expand their earnings lines. When you hover your mouse over the Expense line, you will see small red X icon to the far right - select this to remove the line.
4. At the top of the page, select Finalise Pay Run.

This removes the expense reimbursement from payroll and also updates the journal exported to QuickBooks Online. Expense reimbursements are not reported to the ATO via STP so you will not need to redo the Pay Event or lodge an Update Event.
