Payroll Deductions Online Calculator

Use the Payroll Deductions Online Calculator (PDOC) to calculate federal, provincial (except for Quebec), and territorial payroll deductions. It will confirm the deductions you include on your official statement of earnings.

You assume the risks associated with using this calculator. The reliability of the calculations produced depends on the accuracy of the information you provide.

The Quebec provincial government administers its provincial income tax, Quebec Pension Plan (QPP), and Quebec Parental Insurance Plan (QPIP). To calculate provincial payroll deductions for Quebec, use the WebRAS and WinRAS program from Revenu Quebec.

What you need to know

To limit the risks you take when using PDOC, we recommend that you do the following:

Clear your cache

Clear your Internet browser cache and close the browser after you complete your calculations. Although we do not keep any of the information you enter, the information does remain in your session for up to 30 minutes of inactivity. Information stored within your browser could be viewed by others.

Create your own statements of earnings

Do not use your printed calculations as an official statement of earnings. An official statement of earnings must have certain information that the calculator does not include. Follow provincial or territorial employment standards to create complete statements of earnings.

What’s new

Updated tax rates, effective January 1, 2020.
The CPP formulas outlined in Chapter 7 of the T4127 have been updated with new rates due to the continued implementation of the enhancement.
Results page information from this calculator (PDOC) is now available in row format which allows it to be copied and pasted to spreadsheet or table.

Important Notice: The enhanced Basic Personal Amount (BPA), proposed on December 9, 2019 and outlined in the section “What’s new for January 1, 2020” of the T4127 Payroll Deductions Formulas guide, is now included and functional.

Please note that the CRA is providing time for employers and payroll service providers to make the system and procedure changes necessary to implement the proposed new federal Basic Personal Amount for 2020. As a result, your employer may be using a different federal Basic Personal Amount to calculate your pay. If this is the case, you may see a difference between your pay and the Payroll Deductions Online Calculator. This difference will be reconciled when you file your 2020 tax return.
