How to use webTOD Canadian Payroll Tax Deduction Calculator – Middle Earth Technologies Customer Support

webTOD Canadian Payroll Tax Deduction Calculator is simple to use and can quickly calculate the required payroll tax deduction withholdings for most common payroll payments by Canadian employers, including Regular Wages & Salary, Pension, Bonuses, Retroactive Pay and Commission payments.

The calculator has two modes - Quick and Advanced:

Quick Calculator mode - use this for simple calculations that do not involve additional income or deduction items.
Advanced Calculator mode - use this for more complex calculations involving additional income or deduction items.

The default calculator mode is the 'Quick Calculator'. Quick mode will allow you to calculate payroll tax deduction amounts for all payroll payment types, but only includes data entry fields for basic calculations without any variables for taxable deductions or other tax credits that can be claimed. For example, a Regular Wages/Salary calculation in Simple Mode will only present data entry fields for the payroll payment date, the province of employment, the federal TD1 Claim Code, the provincial/territorial TD1P Claim Code, the number of pay periods in the year, and the Regular Wages/Salary amount for the current pay period.
