Tables on Diskette (TOD)

For easier and more precise payroll deduction calculations, use the Payroll Deductions Online Calculator (PDOC).

Tables on Diskette (TOD) - Effective January 1, 2010 - TOD 2010.2.12.1

What is TOD?

Tables On Diskette (TOD) is a stand-alone computer program that calculates the Canada Pension Plan (CPP); Employment Insurance (EI); and federal, provincial (except Quebec) and territorial tax deductions for all pay periods. TOD is usually updated, as tax changes occur, for January 1 and for July 1. TOD is produced to help reduce the paper burden for small businesses.

In TOD and in the publications T4032, Payroll Deductions Tables and T4008, Payroll Deductions Supplementary Tables, we use the mid-point of a salary range to determine the tax deductions.

If you use TOD to verify payroll deductions formulas, you must use the mid-point of a salary range. If you are an employee who is using TOD to check your deductions, the amounts determined by your employer may differ slightly from TOD's results.

The printed calculations created by the TOD application are not intended to be a statement of earnings and therefore should not be used as such. Please contact your employment standards representative to make sure that you meet the legislative requirements of your province or territory regarding the information that must appear in the statement of earnings.

For Quebec income tax, you can download the WinRAS program from the ministère du Revenu du Québec Web site.
