Summary
In Sage 50 Payroll, a tax refund is incorrectly calculated even though the employee hasn't paid any tax during the year.
Description
In v29.01 and above, a tax refund is calculated for an employee when you process negative pay. This occurs even though the employee hasn't paid any tax during the year.
Resolution
As you can only take a deduction from the gross pay available, as a workaround you'll need to rollback the employee then process their pay again with the correct values.
