What minimum information is required before I can calculate a payroll deduction?

For each type of payroll deduction calculation (Regular Salary/Pension/Bonus/Retroactive Pay/Commission), there are different required information fields that must be completed by the user before a payroll deduction calculation can be done. For all types of income except Commissions, the user must specify a Pay Period definition - i.e. weekly, bi-weekly, semi-monthly, etc. For ALL calculations, the user must also specify the employee's 'Province of Employment', Federal TD1 - Total Claim Amount and Provincial/Territorial TD1P - Total Claim Amount. For Commission income, the user must specify additional information from the commissioned employee's federal TD1X form. Any required information for a payroll deduction calculation will be highlighted in a yellow field with a bolded blue text label beside it. The user must ensure that valid information is provided in these required fields before clicking on the 'Calculate Deductions' button.
