  • webTOD calculates employee payroll deductions for Canada Pension Plan (CPP), Quebec Pension Plan (QPP), Employment Insurance (EI), Quebec Parental Insurance Plan (QPIP), and federal, provincial and territorial (including Quebec) income tax and will allow you to print out a simple Payroll Deductions Calculation results summary, showing your deduction calculations in a clear and easy-to-understand format.

  • You can use webTOD as an alternative to the Canada Revenue Agency (CRA) T4032 Payroll Deductions Tables and T4008 Payroll Deductions Supplementary Tables, or as an alternative to CRA Payroll Deductions Online Calculator (PDOC)webTOD also calculates Québec payroll deductions (CRA's PDOC calculator does not), so it can also be used as an alternative to Revenu Québec's winRAS program. 

  • Use webTOD to calculate Canadian payroll tax deductions on regular salary & wages, pension income, bonuses, retroactive pay increases and/or commission income payments.  webTOD will calculate payroll deductions for any payroll period frequency, including daily, weekly, bi-weekly, semi-monthly, monthly, quarterly and annual.

  • Why use webTOD? Simple - it's easier and quicker to use than looking up deduction amounts in the CRA Payroll Deduction Tables, and provides a more comprehensive, intuitive and user-friendly interface than CRA's PDOC and Revenu Québec's winRAS programs. webTOD will calculate Quebec payroll deductions, while CRA PDOC does not include calculations for Quebec, so webTOD combines two separate programs into one for Québec employers.

  • webTOD runs in most popular (Javascript-enabled) web browsers - so in most cases the only software you need is the web browser you already have installed! We update webTOD for changes in payroll deduction rates and formulas for you - so you never need to worry about whether you have the up-to-date version installed. webTOD is usually updated, as tax changes occur, for January 1 and July 1 each year.

  • Why not try it out?  It's free, it's easy, it's quick and it's accurate.  To use the calculator, simply click on the "Start Calculator" button above.

  • We hope you find webTOD a useful and effective tool. We welcome any feedback, comments, and suggestions regarding webTOD, so please feel free to contact us.
