When you start a new Payrun, the amount the employee is paid, including any deductions or additions, depends on what's been set for the Employee.
Click "Employees" in the main menu and then select the employee you wish to edit and then choose the Pay Options tab.
These values will have come from the employer defaults when the employee was first created.
Here you set the basic amount that the employee is to be paid on every payrun. This value is automatically added to the payslip and used the Pay Code 'BASIC'
You have the option to set Leave Adjustments to manual or automatic.
If it's set as automatic then the amount the employee is paid will be automatically reduced to reflect any unpaid leave or statutory pay in the period.
If you set it to manual then you'll need ot manually reduce the basic pay on each payrun, however any Statutory pay that required will still be automatically added to the payslip.
Here you can set any additions or deductions that you want to automatically include on every payrun.
Just click the 'New Addition/Deduction' to create a new entry, although you may want to first create a new Pay Code.
This is where you set the Tax Code and National Insurance values for the employee.
You can also set an option to not pay Secondary NICs
This tab contains a number of options that don't neatly fit under the other tabs.
The Student Loan and Postgrad Loan fields are the only options here that affect the amount the employee is paid.
All the other options here determine what information is provided to HMRC on an FPS.
