Payroll Deductions Online Calculator
Notice to T4032/T4008 Users:
As mentioned in the T4032/T4008 Guide Section A, use the Payroll Deductions Online Calculator (PDOC) for the following situations:
- the employee reaches the Year’s Maximum Pensionable Earnings (YMPE) of $66,600 or;
- a payment of remuneration, if annualized by the number of pay periods in the cycle, is over the YMPE of $66,600
PDOC uses exact salary figures and accordingly calculates the deductions provided by the CPP additional contribution for all scenarios. For this reason, PDOC results takes precedence in the above situations.
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 program from Revenu Quebec.

- On March 3, 2022, amendments were made to Subsection 100 (3), paragraph 60 (e.1) of the Income Tax Regulation, ensuring Canada Pension Plan (CPP) additional contributions are treated as a deduction at source. Please note, this deduction is not displayed separately on the Result page. However, the deduction is used in the calculation of the federal and provincial tax.
